Why was the Washington consensus irresistible in Latin America Essay

For what reason was the Washington accord compelling in Latin America - Essay Example Inside the current globalized framework, the significance of universal political economy and the methods by which choices of financial significance are locked in, the general degree of importance is expanded. As an element of this, the accompanying investigation will connect with the peruser with a comprehension of why the â€Å"Washington Consensus† became so broadly acknowledged and settled upon by a reiteration of various Latin American nations. Albeit only referencing the Washington Consensus, and the determinants that it fundamentally forces, would be a compelling beginning, the examination will likewise incorporate with an inside and out conversation of every one of the 10 focuses which incites the Washington agreement as a methods for understanding a definitive fascination that such a large number of Latin American nations had to this specific monetary coordination and approach (Marangos, 2008). Further, the remarkable disadvantages and unsaid ineptitudes that the Washi ngton Consensus will likewise be examined concerning the manner by which partners inside this specific issue understand that it was to their greatest advantage to acknowledge the Washington agreement even with its implicit degree of downsides. ... cit level of comprehension regarding world issues, worldwide relations, and political hypothesis will essentially be locked in and ideally comprehended (Arestis, 2004). History/Background Firstly, before diving into a definitive method of reasoning behind why such a large number of Latin American nations decided to incorporate so completely and totally with Washington accord, it must be comprehended that key full scale financial factors all through Latin America incited and conjured a degree of more noteworthy collaboration and eagerness to endeavor an unexpected methodology in comparison to might have been understood that some other point ever (Babb, 2013). When of the 1980s, Latin America, notwithstanding a significant part of the remainder of the world, was all the while reeling from the financial repercussions of the worldwide disquietude that had existed for very nearly 10 years during the 1970s. Though the United States, and the remainder of the world so far as that is concerne d, felt the effect of the exceptional increment in fuel costs that occurred during the late 1970s and mid 1980s, the effect this had after creating countries were considerably increasingly significant (Duncan, 2003). This makes sense because of the way that the United States and other created countries had a degree of riches that could be utilized against an abrupt value vacillation as for an inelastic interest. What eventually incited the oil emergency during the 1970s had to do with the rising degrees of obligation, detachment of remote credit, and a limitation in worldwide exchange (Ruckert, 2006). Though the fuel emergency of the 1970s and mid 1980s was obviously of importance, it should additionally be comprehended that this specific issue was a huge contact with respect to creating countries around the globe; particularly Latin American nations. The justification behind this is because of the way that Latin

Current Events Roundup, September COLUMBIA UNIVERSITY - SIPA Admissions Blog We are currently in week four of the Fall 2018 semester, and its already been a busy four weeks for fellow Seeple students. Between the General Assembly this week, Alexandria Ocasio-Cortez visiting Columbia to speak with Professor Joseph Stiglitz and SIPAs Director of the Technologies Specialization, Anya Schiffrin, and the Rise of the Rest Entrepreneurship  Across America event, there have been plenty of things to discuss and attend. Below is a roundup of some notable September events: The UN General Assembly The UN General Assembly is certainly an eventful time in New York. Aside from the  bumper to bumper traffic and multiple street closures that take over Midtown East, it is one of the few instances where there is such a high concentration of world leaders in New York City at once. This is, of course, a significant point of interest for SIPA students, who in addition to taking geographic advantage are able to participate in the many intersections of SIPA and the United Nations, including classes and events. This year, the General Assembly has been an especially notable one, much of the conversations will center around three key issues: the Rohingya crisis, Syria, and the Iran Nuclear Deal. The UN Secretary General Antonio Guterres called for an implementation of the Paris climate change agreement. Coverage of the UN General Assembly has varied, but a few key moments have stood out, in particular, the President of The United States decision to not meet with Iranian President Hassan Rouh ani, among other things. Either way, SIPA students have been busy discussing the General Assembly and keeping a close eye as it will continue to be a key topic in classrooms through the semester. Alexandria Ocasio-Cortez visits Columbia University   On June 26th, 2018 Alexandria Ocasio-Cortez became a household name as a Congressional candidate who won the Democratic primary in New Yorks 14th Congressional District and beat the incumbent Congressman, Joe Crowley. On September 24th, 2018  she joined Columbia Business School Professor and Nobel Prize-winning economist Joseph Stiglitz and SIPAs Director of the Technologies Specialization, Anya Schiffrin at the Roone Arledge Auditorium at the Riverside Church for a discussion panel. Students were able to attend and ask questions. Much of the conversation centered around grassroots efforts and Ocasio-Cortez spoke of an increasingly mobilized progressive base and encouraged students to engage in on-campus activism. She also spoke to the Democratic partys increasing isolation of marginalized communities. She stated that it was important for Democrats to engage minority voters through a renewed commitment to their communities. SIPA students were also in attendance. The Rise of the Rest Entrepreneurship Across America   On September 12th, 2018 Dean Merit E. Janow, Steve Case, and Secretary Jacob J. Lew sat down for a fireside-chat discussion on entrepreneurship in America. Case, Chairman, and CEO of Revolution and the Co-founder of AOL talked about his Rise of the Rest initiative to support entrepreneurship across America. Secretary Lew spoke of policy changes to encourage entrepreneurship, improving immigration policies, for example, can promote entrepreneurship given the high percentage of immigrant founders. They also touched on the impact of a healthy economy on the development of ideas as long as ideas are strong and people are motivated, the health of the economy becomes less important. The fireside chat ended with a discussion on the regulation of online businesses is it possible to apply the same levels of regulations that are applied to brick and mortar businesses?

John Steinbecks Of Mice and Men Essay - 976 Words

John Steinbecks â€Å"Of mice and men† Of Mice and Men is set along the Salinas River a few miles south of Soledad in the fallen world of the Salinas Valley, which Steinbeck places east of Eden the Promised Land is only a painful and illusory dream. This land is populated by sons of Cain, men doomed to walk alone. One of the major themes that comes from this is loneliness, or fear of apartness. One of the themes of Of Mice and Men is that men fear loneliness, that they need someone to be with and to talk to who will offer understanding and companionship. Soledad is a Spanish word and translates into English as solitude or loneliness. This country is one of such loneliness that George and Lennie stand out sharply because they†¦show more content†¦It is impossible to live where they are so the safe place becomes a little home. Steinbeck is not only able to dramatize Lennies desire for the safe place through his love for the rabbits, but he is also able to define on a low level of consciousness that desire the most important aspect of their plans for Lennie is the attraction to soft, warm fur. This transfer from the farm to the rabbits is also important because it makes possible the theme of action. The dead mouse which Lennie carries in his pocket in the first chapter introduces this. As George talks about Lennies attraction to mice, it becomes clear that the rabbits will come to the same end crushed by Lennies simple, uncontrollable strength. The readers see a pattern after they read about how Lennie killed the mouse and the puppy. Also, Georges story that he tells twice about the girl with the red dress and the crushing of Curleys hand, the shooting of Candys dog, and the frequent appearances of Curleys wife contribute to this expectancy of patterns. All of these incidents are patterns of the theme of action and predict the fate of the rabbits and thus the fate of the dream of the safe place. Lennie asks George, Tell me like you done before, He repeated his words rhythmically, as though he had said them many times before. It is shown that even Lennie has heard it by his repeating the exact language.

Crystallization Definition

Crystallization is the solidification of atoms or molecules into a highly structured form called a crystal. Usually, this refers to the slow precipitation of crystals from a solution of a substance. However, crystals can form from a pure melt or directly from deposition from the gas phase. Crystallization can also refer to the solid-liquid separation and purification technique in which mass transfer occurs from the liquid solution to a pure solid crystalline phase. Although crystallization may occur during precipitation, the two terms are not interchangeable. Precipitation simply refers to the formation of an insoluble (solid) from a chemical reaction. A precipitate may be amorphous or crystalline. The Process of Crystallization Two events must occur for crystallization to occur. First, atoms or molecules cluster together on the microscopic scale in a process called nucleation. If the clusters become stable and sufficiently large, crystal growth may occur. Atoms and compounds can generally form more than one crystal structure (polymorphism). The arrangement of particles is determined during the nucleation stage of crystallization. This may be influenced by multiple factors, including temperature, the concentration of the particles, pressure, and the purity of the material. In a solution in the crystal growth phase, an equilibrium is established in which solute particles dissolve back into the solution and precipitate as a solid. If the solution is supersaturated, this drives crystallization because the solvent cannot support continued dissolving. Sometimes having a supersaturated solution is insufficient to induce crystallization. It may be necessary to provide a seed crystal or a rough surface to start nucleation and growth. Examples of Crystallization A material may crystallize either naturally or artificially and either quickly or over geological timescales. Examples of natural crystallization include: Snowflake formationCrystallization of honey in a jarStalactite and stalagmite formationGemstone crystal deposition Examples of artificial crystallization include: Growing sugar crystals in a jarProduction of synthetic gemstones Crystallization Methods There are many methods used to crystallize a substance. To a large degree, these depend on whether the starting material is an ionic compound (e.g., salt), covalent compound (e.g., sugar or menthol), or a metal (e.g., silver or steel). Ways of growing crystals include: Cooling a solution or meltEvaporating solventAdding a second solvent to reduce the solubility of the soluteSublimationSolvent layeringAdding another cation or anion The most common process is to dissolve the solute in a solvent in which it is at least partially soluble. Often the temperature of the solution is increased to increase solubility so the maximum amount of solute goes into solution. Next, the warm or hot mixture is filtered to remove undissolved material or impurities. The remaining solution (the filtrate) is allowed to slowly cool to induce crystallization. The crystals may be removed from the solution and allowed to dry or else washed using a solvent in which they are insoluble. If the process is repeated to increase the purity of the sample, it is called recrystallization. The rate of cooling of the solution and the amount of evaporation of the solvent can greatly impact the size and shape of the resulting crystals. Generally, slower is better: slowly cool the solution and minimize evaporation.

What makes a building green Free Essays

string(57) " for Dryvit Wall System Steady State Thermal Analysis\)\." This paper explores what makes building material green. Green building materials are materials that have less impact on the environment, human health, economy and productivity as well. Since buildings have significant impacts of the environment, design professional have resolved to the use of green materials in building process so as to eliminate waste and to conserve the environment. We will write a custom essay sample on What makes a building green or any similar topic only for you Order Now Construction of buildings consumes a lot of energy use and also emits a lot of carbon dioxide in the environment. Construction also consumes a lot of raw material each year. Buildings made from green material are healthier, energy efficient than other buildings and more durable. This paper will concisely articulate what sustainability and green building products are. This paper will also determine and explore if a product is green. Lastly, this paper will evaluate the relative greenness of different products. Table of contents Introduction 4 What is Sustainability? 5 Exploration 7 Green Building Products 7 How to determine a green product 10 Implementation 12 Conclusion 21 Works Cited 22 What makes a building material Green? Introduction Construction of buildings has intense environmental, health, economic and productivity impacts. 20% of global energy use is from buildings. Buildings also emit 20% of carbon dioxide to the environment. For these reasons, many builders have resolved in the use of green building since it has financial, health and environmental benefits. Many countries that practise sustainability have also supported the green building movement. Statistics in the U. S. show that green building construction will rise from 2% in 2005 to 10% of the constructed buildings by the year 2010 and therefore the country will have save about $30. billion. The green building initiatives in the U. S. has established more that 80 green building programs both regionally and locally. The local governments are also involved in the promotion of the green building by creating innovating ways of supporting the programs (NACo Green Government Initiative 1). In Europe and North America, many architects are involved in designi ng sustainable designs also known as the green building designs. This is due to their clients’ demands and their recognition in protecting the environment. Globally, there is a lot of support form the people in establishing environmental friendly buildings (Pearce 129). There is need of financing low energy buildings so as to enhance performance. Governments should initiate more programs that enhance building of green buildings. This process will therefore eliminate the environmental hazards and increase global health standards while reducing costs (Baden et al. 8-1). The green building has made tremendous benefits globally. The initiative has help in the conservation of the environment, health and financial issues (NACo Green Government Initiative 1). What is Sustainability? Sustainability is being responsible to the world especially environment and in energy saving. Sustainability is a social program that helps in energy saving and other global protection of the environment. It deals with issues on the environment, economy and society (Langdon 6). In order for the building process to be sustainable, there is need of taking care of the environment, health issues and the finances of the society. Sustainability has led to the establishment of green buildings since it helps in the protecting the air we breath (Wiaderski 2). Green buildings prevent the particles such as Volatile Organic Compounds off-gassings, carcinogenic among other airborne particles from filling people’s lungs. Green building eliminates the use of paints and adhesives that emits these volatile organic compounds. The process of using green materials such as the Dryvit coatings and adhesives, which are water based helps in the elimination of the harmful chemicals in the environment (Wiaderski 3). Many hospitals and schools are being sustainable by using green materials in the constructions process. This has therefore helped in ensuring that people live in environments that are safe and healthy. For sustainability to be ensured, designers are now using green materials that are environmental friendly (Wiaderski 3). To ensure that there is sustainability, there are many building standards that have been introduced. For example the National-recognized green building rating standards have been established for the builders and designers to ensure that they are making buildings that are protect the environment and the health standards of the people (NACo Green Government Initiative 3). In sustainability, builders try to eliminate the use of fibreglass insulation and other such products in order to protect the human health standards. This is the reason why builders use the Dryvit system in insulation since it helps in the improvement of the quality of the air in building (Wiaderski 4). To ensure sustainability in green building construction and design, the major factors to consider are efficiency in energy and other resources. This is done by ensuring that the designed buildings should of low energy consumption. This is practical by the use of the Dryvit systems which adds a constant insulation layer on the exterior walls of a building. The Dryvit system also minimizes the thermal breaks of the building. This process of insulation of the exterior wall helps in energy conservation and it also improves the indoor air quality of a building. Insulation also helps in resisting bad weather conditions. Insulation of the exterior walls is also advantageous to the northern climates since it increase the temperature of the wall cavity which therefore helps in the minimization of the condensation process inside the cavity of the walls. This process is also advantageous to the southern climate since it helps in reducing the air infiltration therefore protecting the wall cavity by minimising the entry of the heavily saturated moist air. This helps in the reducing mold growth and condensation on the wall cavity (Wiaderski 4). A study conducted by Oak Ridge National Laboratories on the building material concludes that the Dryvit wall system is a building system that conserves energy of the wall system and therefore it was suggested that the system should be used in the commercial construction of the U. S. buildings (Kosny et al. Whole Wall Rating / Label for Dryvit Wall System Steady State Thermal Analysis). You read "What makes a building green" in category "Papers" For sustainability, designers need to use products that protect the economy of the people and the country. Green products are durable and they also don’t need be maintained and repaired constantly. One practical example is the use of the Dryvit syst ems which is adaptable. This systems’ repair and maintenance process does not need to be harshly removed nor does not require demolition (Wiaderski 5). The base coat of the green products has a reinforced mesh that is embedded on them to ensure durability and resistance for more than 30 years. Since the green products are durable and resistant, they have been found to be cost effective. For example the Dryvit systems have been found to be cost effective due to its durability and other advantageous aspects (Egan et al. Projected Life Cycle Cost of Exterior Insulation Finish Systems). There are green building practices that help in the sustainability. This includes the use of the indoor air quality. In this practice, the designers and the builders ensure that they make buildings that have quality indoor air systems. This practice involves concepts such as relationships of the ventilations and the indoor air. Other concepts include the use of the simple dose in building process and source identification. Other concepts include strategies and options of source control and design and operations of ventilation systems. There are other concepts such as the selection and specification of material and procedure of construction. Lastly, other concepts for best practices in the construction process include the maintenance, operation and renovations (Levin Best Sustainable Indoor Air Quality Practices in Commercial Buildings). Exploration Green Building Products Green building products are materials that have less or none impacts of the environment. These materials are not hazardous materials and they allow for the eradication of the other hazardous building products. There are many classifications of green products. In the classification of the green building products, the building products are evaluates using their negative and positive impacts and thereafter, the products with most positives are classified as a green product (Wilson Building Materials). There are products that fall into multiple classifications and others that fall into one classification. The classifications of the green products include durability, zero-gassing, toxicity, longevity and resource efficiency. Other classifications include environmental impacts and energy efficiency. Green products are building products with various environmental and cost benefits. Green products have long-term performance benefits (Wiaderski 2). Green products are combined with the building designs to help in the reduction of the negative environmental effects. Deign and building professions the use the green designs ensure that they give vigilant attention to the aspects that oversee the projects’ designs. Buildings made from green products are airtight and therefore keeps the buildings from interior and exterior contaminations. Constructions that use green materials ensure that there is a healthy environment to the people in the society (Wiaderski 2). The green products are classified in the category of energy rating, life cycle costs and health conditions (Wiaderski 4). The common features of the green buildings include the energy conservation in which include factors such insulation, mechanical equipment and efficient lights as well. The other feature include the utilization of solar energy in which factors such as space heating, cooling and water heating are considered. There is also the water conservation feature which ensures that there are fixtures of low consumption. Other features of the green products include the recycled material incorporation and materials with low emissions improved indoor air quality ventilation (Levin Best Sustainable Indoor Air Quality Practices in Commercial Buildings). The other features of the green products include the development sites that less destructive to the environments which include processes such as run-off control, water courses and other natural habitats preservations. The other feature is the treatment of the on-site waste water. There are also features such the use of refrigeration and fire systems that have compounds that reduce or eliminate ozone-depletion. The other feature include the use of life cycled materials and assessment of the building projects’ environmental impacts. The last feature of the green products is the use of recycled products (Levin Best Sustainable Indoor Air Quality Practices in Commercial Buildings). Green building materials are sustainable to the environment since they help in the improvement of the health standards of the people. These are recycled materials that are highly durable. These products are categorised in criteria such as the resource efficient products which include products such salvage products, post-consumer and pre-consumer products. This category also includes products such as waste agricultural materials. The green products also include product that are non toxic which include products such as the natural processed and non ozone-depletion products. This category also includes non hazardous products and other environmental protection products. The other category of the green products includes the energy and the water efficiency products which include products such heat reducing building components and energy conserving equipments. Other products include the energy renewable equipment and water conserving equipments (Port 3). The last category of the green products includes the safe and healthy built environment products. These products include the non-pollutant products and products that reduce the contamination spread. Other products that are in this category include the indoor pollutants removers’ products and products that are used in warning about health hazards. Other products include that are light improvers and help in the control of noise. Lastly, this category includes products that help in community well-being’s enhancement (Port 3). Homes that are made from green products are durable, healthier and more efficient that other home. Components of a green home include selection of strategic sites to reduce environmental impacts. The other component is designs that help in conserving water and energy and waste. The other components include designs that minimize usage of materials and therefore reduce the needs to maintain the homes. Homes made from the green materials possess components that are recycled and are therefore efficient to the energy conservation. These components also use sources that are renewable (NACo Green Government Initiative 1). Green products have been used by the USA’s Green Building Resource Centre. These products help in the conserving the energy, water and natural resources. The products also help in the protection of the indoor environment of the buildings (Levin 465-482). How to determine a green product Green products are determined by how they meet the requirements of the performance. These requirements include the factors such as being sufficient and durable. The other requirements of the performance include the strength predictability and stability. Other requirements are such as moisture, decay and bio-contamination resistance and have less cost compared to other products. The other requirement includes factors of being non-toxic and non-hazardous to the people around. Lastly, these products are able to be efficiently and effectively installed (Pearce 3). The other way to determine whether a product is green is by ensuring that the product is not negatively an impact to the ecosystems. In this way, one should ensure that the product is harvested sustainably and is also non-accumulative and non-toxic to the environment. Another way of determining the product id this category is by ensuring that the product is recyclable and is cost effective since it does not have to be repair and maintained. Products in this criterion also produce waste that can be reused and recovered (Pearce 4). Another way to determine the green products is by ensuring that the products are able to be renewed. In this criterion, the products are checked is they are renewable and if they can be harvested sustainably. The other things to consider are whether the products are materials that are closed loop. This means that the products should be checked whether they are reused or recycled. Other things to consider in this criterion are things such as whether the product is adaptable or reusable and also whether they are non-renewable. Lastly, the products are checked whether they use unsustainable material (Pearce 5). The other factors that determine whether a product is green include factors such as green products saves energy. In this factor the products are determined whether they help in the reduction of the heating and cooling loads. Other factors are whether the products use reduces energy levels. Lastly, the green products are products that can produce energy. Products can be determined as green products when they protect the natural resources. In this factor, the products are checked whether they have recycled content and whether they are made from agricultural waste. Products that use less material and are made from materials that are swiftly renewable also fall in this category. The products in this category are those that are made from managed forest and are also products that are salvaged (OFGEM A review of the Energy Efficiency Commitment 2002-2005). The other factor that can make a product green is when they can conserve water. The products include those that can conserve and consume less water. The other way to determine whether the products are green is by checking whether the products have contributed in the safety and healthiness of the indoor environment. In this way the products are determined whether that have effects on the indoors. Such products should not release and pollutants in the buildings. Products in this category do not remove pollutants in the indoor environment (Mendell 227-236). Lastly, products can be determined to be green when they reduce the impacts of buildings on the community. These products are those that moderate the storm water effects and also help in the provision of access to transportation modes that are alternatives to other transportation modes. These are also products that treat without the use of the chemicals and also do not components that deplete the ozone (Levin 173-175). Practical examples of the buildings and projects which are among the 10 winners of â€Å"What makes it green 2008 winners† that have been used in the illustration of the green products include the Bertschi School in Seattle WA which was helped the people in the area to minimize the usage of transportation. The other example is the Centre of Urban Waters project in the Tacoma that is used in storm water runoff reduction. The other illustration is of the Corvallis CoHousing project in the Corvallis which has ensure that the there is minimization of the use of the resources through sharing. There is also the illustration of Kitsap Sustainable Energy and Economic Development that encourages clean energy development (Dispenza Green Building Elements: What makes it Green? 2008 Winners). Implementation The greenness of products can be evaluated from different perspectives for example according to their durability, stability, strength and speed. The greenness of products can be judged from the way a product or a material reduces its demand for landfills especially the cement company Ceratech in the U. S which makes use of recycled fly ash to manufacture Redimax cement. Ceratech, Inc a technology company for materials focuses in the enlargement and the commercialization of inventive green cement sustainable knowledge (Stone 1). The Romans used the volcanic ash (Pozzolan) which they mixed together with lime in order to manufacture the cement for constructing Coliseums, Pantheon and Pont du Gard Aqueduct in Southern France which are strong to date. Pozzolans include fly ash, timber ash, slag and residue from publicly consequential garbage which are blazed at elevated temperatures. The Ceratech Company uses fly ash in producing Redimax which is their cement for all household productions though it manufactures its cement locally by using Class N volcanic ash pozzolans to produce their cement. Fly residue, is a diaphanously alienated coal incineration derivative which is collected by electrostatic precipitators from the chimney gases. A rough calculation of 60% which equals to 42 M tons of fly ash is land filled in the U. S. per annum (Fanney et al Second International Green Building Conference and Exposition). There is a reduction in carbon footprint of concrete due to the replacement of Portland cement with fly ash since the production of a single ton of Portland cement gives production to roughly one ton of carbon dioxide. Ceratech technology of revolutionary cement is a footstep of change to the industry of construction by providing the cement which is environmental friendly and is engineered for its potency, momentum, permanence and its long-standing toughness. Fly ash which is a post industrial fritter away stream is utilised by Ceratech, in order to produce structural cement of high presentation worldwide encompassing of more than 90%materials from cast-off waste (Stone 3). The recycling process preserves the virgin material hence eliminating the mining of raw materials which are needed to produce Portland cement. It also reduces the emissions of carbon dioxide by making the replacement of Portla1nd cement to every ton of Portla1nd cement produced. World wide, Portland cement gives a contribution of 6% to 8% of all the gases of Carbon dioxide released per year (Consoli et al Guideline for Life-Cycle Assessment: A `Code of Practice’ Society of Environmental Toxicology and Chemistry). There is also the reduction of the energy consumed since the Ceratech Company is produced by the use of an amalgamation process of low energy powder against the calcining process of high temperatures. The Ceratech Company has done a careful manufacturing of their cement for the applications where strength, durability and strength are the preferred distinctiveness of a substance. There is competence of energy since their Pozzolanic cement requires 99% less energy to produce a corresponding amount of cement from Portland (CERATECH Green Sustainable Structural Building Material Technology: Driving Change through Innovative Thinking). The logistics behind the Redimax cement is that, it is shipped, handled, stored and batched like the Portland cement and it can either be transported by rail, truck or barge. Since the dangerous constituent of sustainable1 construction is durability, there is a designed subject to allow Ceratech maximizing the performance characteristics in order to come up with the constructing concrete which will last for long. The deterioration resistant of Redimax, low permeability does helps in resisting the establishment of the corrosive cell within the ma1trix of the concrete and in so doing there is eradication of characteristic costs which associate with the traditional corrosion performances of protection, coatings and sacrificial fundamentals. Hence there is extended cycle of the life of a construction. The strengths of green material can also result from its comprehensive strength since the cement concrete acquires rapid characteristic of hardening so that it gives an easy generation of more than five hours comprehensive strengths of 2,000 psi without any negative impact working time (CERATECH Green Sustainable Structural Building Material Technology: Driving Change through Innovative Thinking). The Sulfate Resistance of the cement evaluates the greenness of the product by examining its uniform density and extreme fine pore structure which increases its resistance to the penetration by water or substance. There is evaluation of greenness of products in terms of Improved Flexural Strengths whereby when they are associated with Redimax there is a typical of 15% to 18% compressive strengths of correspondence. There is an allowance of reduced loading stress from the cement in order to substrate for slab on grade work more effectively than the Portland cement concrete. The enhancement of flexural capabilities does provide for potential incorporation to longer spans fore important applications which are structural (CERATECH Green Sustainable Structural Building Material Technology: Driving Change through Innovative Thinking). The greenness of a product can be evaluated in terms of the expenses for instance the Ceratech construction expenses were reduced together with its direct and indirect value of the building project which leads\to the enhancement of the breadth of a company’ s exclusive cement distinctiveness. The construction costs include reduced labour costs which are as a result of the compression of the project schedule. The compression also diminished costs, for charter items such as shoring organization, formwork and special apparatus. There is also the reduction of eliminate issues which are in association with the rejected concrete due to the discharge requirement of water within a period of 90 minutes. The construction cost reduction leads to the reduced prices in material costs by as much as 30% (CERATECH Green Sustainable Structural Building Material Technology: Driving Change through Innovative Thinking). There is also operating costs which lead to the decrease of heating and cooling costs due to decrease on the whole thermal mass of the building. There is also outstanding confrontation to damage from the liquefying congeal, scaling and chemical assaults and the extension of the suitability for local, situation and centralized taxes by means of GREEN inducement curriculum. There is also maximized reduction on saleable space expenses for example the reduced size structural mechanism by means of greater square recording. The evaluation of the greenness of a product can be gauged in terms of the innova1tion, aesthetics and environmental leadership. Innova1tion can be observed from the superior mechanical properties in order to give allowance to the increase in the usable space by decreasing the column footprints, breadth of the slab, the height of the ceiling and the increased free distance lengths. There is also the increase of 30% in the increase fire charges. The other evaluation of greenness in innovation on innovation is the creation of blast dead set against structures, the rapid build dry piled block structures utilizing the innovatory and also the design storm resistant colossal stonework structures (CERATECH Green Sustainable Structural Building Material Technology: Driving Change through Innovative Thinking). There is also the environmental leadership which entails the requirement of the technology of the product company as either stonework block concrete. This will do away with a single ton of carbon dioxide gas for every 3 yards of concrete. The efficiency, strength and safety of a product can brought out thr3ough greenness by the example of the technology of Ceratech cement technology which exceeds ASTM-C-1600 in all the groupings of testing. Whereby increase in the power gives allowance for greater suppleness of design, efficiency and the general presentation of building. The greenness of the product can also be observed from the efficiency of the design for instance in the Ceratech Company whereby the ultra high strength hollow core floor board consent to greater free duration extensions. There is reduction of overall weight of building whereby columns which cross sections can be reduced by a nearly percentage of 40%. There is also reduction of rebar requirements. The strength of the product can bring out its greenness like in the case of Ceratech who have compressive strengths to 10,000 psi using standard mix designs with high early strengths to 2,000npsi in 6hours (CERATECH Green Sustainable Structural Building Material Technology: Driving Change through Innovative Thinking). The use of green building construction, is of great benefit to the consumers since it is efficient in energy, water and materials, it minimizes waste and pollution and creates a better indoor environment. Designing of buildings is aimed at humanizing interior excellence of the surrounding which can bring into being benefits for workplaces and the productivity of the workers as well as the landlords. A proficient green structure can be strong enticement when giving promotion to the charter of residential or marketable space. According to environmental protection agencies, deprived interior air quality is an environmental threat to a nation. Whereas sick building syndrome causes fatigue and illness which is brought about by poor designed ventilations and the presence of biological contaminations for instance molds, bacteria and pollens. The indoor air pollutants can be as a result of smoking of tobacco, building resources, products for beautifying, practices for clearing out, pest management, supplying, dust together with other activities such as cleaning and heating up (Stone 4). Due to poor green construction, there is a possibility of occupants complaining of several indications such headache, irritations in the eyes, nose and exasperation of the throats, dry coughs, itchy skin, wooziness and vomiting, difficulty in concentrating, exhaustion and sensitivity to scents. Relieve from the suffering, comes about after leaving the building. T he Sick Building Syndrome reduces the efficiency of the workers which may lead to increased non-attendance. Green construction indemnifies appropriate exposure to air, condensed particulate substance and substitutes to pollution of chemical as long as preservation and modifying activities work in performance with the intention of the established green materials and systems when the construction took place (Stone 4). The elements of design of a construction play an important role in eradicating interior contaminants. Therefore, there is an importance of integrating permanent entryway features for example grills or grates which will be used to capture dirt and particulate substance at all entryways with heavy traffic. The buildings should also include controls of tenants for airflow, temperature and lightning. The possible options have to include task lighting, operable windows and under-floor heating, aeration (ventilation) and air habituation (HVAC) arrangements with personal diffusers. There should be a possibility of the proposal of the building maximizing the quantity of proscribed daylight that can reach interior regions which are occupied. The prohibited day lighting involves reflective exteriors and disseminating elements which enable sunshine diffusion while taking control of frown. Additionally, light sensors should be installed to supplement the total amount of sunshine to supply desirable lighting levels for the necessary errands (Lippiatt 37-45). The relative greenness of a product can be evaluated from scrutinizing the construction resources, supplying, and other products such as air fresheners, clearing products and pesticides which in the end result can discharge contaminants more or less incessantly. Therefore, there is a proposal of Formaldehyde-free materials for floor covering, furniture, fortifications and upper limits, lagging and finishes, sub-flooring and en suite breakfronts. Preferably all the bonding agents and paints should not have any fillings of Volatile Organic Content (VOC) but instead ordinary and water-based coverings should be used. Low and no-discharge grounds and flooring finishes, natural coverings of the floor are of greatly preferred to conventional carpeting (Stone 5). An observation from United States Environmental Protection Agency (USEPA) the financial benefits of residential green building, there is a production of $200-$400 in annual savings in energy from the houses which are built to Energy Star. This are all on heating, cooling and water heater related costs. The durability of the green home construction interprets to additional savings on the preservations over the existence of a home (Internal Revenue Service Treasury and IRS Provide Guidance on Energy Credit to Home Builders). There is an important role which is played by the counties in educating the residents and builders of homes, about saving energy and obtainable refunds, recognitions and other funding support for green structure and projects for home development (Weitz et al. 5810-5849). The counties can give an action of Clearinghouse of information for builders and confidential citizens who have an interest of capitalizing on the benefits of investments of their green building schemes. The incentives of finance in order to build green, come in different forms including credits from taxes, for individual taxpayers, accelerating process of giving permission for homebuilders and rebates from both power and water companies for doing the setting up of resource competent attributes in a residence (Roodman et al A Building Revolution: How Ecology and Health Concerns are Transforming Construction). The available incentives and rebate programs available to landlords and homebuilders include the Federal Energy Policy Act Tax Incentives whereby this act of Federal Energy Policy Act 2005, presents the inducements of tax for both acquiring and installing competent energy productions in building. This proceed comprises of credits to builders and customers for green structure schemes, enhancements of energy economy home and solar energy organizations (Internal Revenue Service Treasury and IRS Provide Guidance on Energy Credit to Home Builders). On the national Ratings Certifications and Standards, the recognized national ratings, standards systems and certifications of green building can be exceptional gear for regions for employment when coming up with own residential curriculums for green building. There can be customization of national programs in accordance to the differences of the region while giving provision of approval framework on which counties can come up with their own advancement of green building. Therefore there is a widespread network which has provided allowance to the national programs to bring together case studies and al1 the best information practices from all through the U. S (EIA Analysis of 10% renewable Portfolio Standard). There are a number of green building ratings, certifications and standard programs which are countrywide well known and may be given a priority to come up with programs of green building. They include, LEED for homes which is a USGBC with a mission of advancing the revolution of the market of the environment which is constructs, increases and supervises the LEED for the rating systems of homes which were put into action in 2005 and gave provision to a tool for certifying homes that are given a design in order to be energy, water and efficient of resources and built with the health of future occupants being considered. There is also the Centre for Communities by Design whereby the American Institute of Architects (AIA) Centre for Communities by Design does provide support to the societies on sustainable planning through its curriculum of Sustainable Design Assistance Team. SDAT’s undertaking is to provide methodological support in order to hold up communities come up with the vision and the construction for a sustainable future (EIA Analysis of 10% renewable Portfolio Standard). Conclusion The discussion in the paper was based on the green building products and their sustainability of Construction. It seems that, in many cases, the best alternative of a design for interior surrounding quality gives a determination on the excellence of the general atmosphere. Therefore the elimination of air contamination in the indoor will be determined by the durability of the building material which will hence need lower quantities and less toxic chemicals for the maintenance and renovation (Levin Best Sustainable Indoor Air Quality Practices in Commercial Buildings). The paper focused on the implementation and exploration of the green products for construction. There is also the evaluation of the greenness of construction materials which can be evaluated in different ways including valuing the durability, stability, strength and speed of the materials (Levin Building Design and Material Selection). The greenness of products is judged from the way a product or a material reduces its demand for landfills especially the cement company Ceratech in the U. S which makes use of recycled fly ash to manufacture Redimax cement. There are also energy policy acts which are featured on the paper which focus on means of saving the energy (EIA Analysis of 10% renewable Portfolio Standard).

Contemporary ICT and Engineering Issues

Question: Discuss about theContemporary ICT and Engineering Issues. Answer: Digital Business Digital Business is the process of creating new and improved business designs by the procedure of blurring out the physical and digital worlds.[1] Digital Business is a broad topic that caters the demands of digital customer and is an amalgamation of e-commerce, collaborative economy and APIs.[2] Digital Business refers to the set of methods and procedures that fulfill the customer vision by creating new values in the market and builds foundation capabilities that support the overall architecture.[3] I agree with the first definition as digital business is much more than e-business due to the presence of a number of components and entities belonging to the physical as well as the digital. It is rightly an amalgamation of both of these fields. I partially agree with definition two as the demands of the digital customers are definitely met by the digital business but it is way more than e-commerce or collaborative economy. It is a massive integration of things, people, ideas and strategies. I agree with definition three as the customer vision is met by the methods of digital business and it has definitely provided new values in the market and has provided the existing practices a complete transformation. Digital business is a real concept as the present era is an era of digital innovation and technologies. The customers and their demands also revolve around the digital media and methods. Digital business, thus, provides a set of methods that can achieve the same by integrating a number of physical ad digital entities. Internet of Things Internet of Things (IoT) is a network of objects that are connected together from various mediums and sources and function together in the presence of network which is mostly the Internet. IoT is a disruptive trend as it is set to introduce new value creation and value capture in the market. It disrupts the business models by succeeding a shift of mindset associated with customer needs, offering, and role of data, control points and capability development as well.[4] Big Data The three characteristics of Big Data are as described below: Volume Big data comprises of massive volume and huge chunks of data for a particular organization or an industry and comprises of structured, semi-structured and unstructured data. Velocity In the traditional practices, data was gathered with the aid of batch processes. However, Big Data allows gathering and collection to take place in real time and thus enhances the velocity of the entire process. Variety Format is no longer a constraint during data gathering, collection and analysis and the same is a prime characteristic of Big Data. It stores, handles, analyzes and manages varied data types and formats.[5] Social Media Web 1.0 Web 2.0 It is a readable phrase of the World Wide Web (WWW) It is the writable phrase of the World Wide Web (WWW) It comprises of flat data It comprises of interactive data It basically allows the users to provide information and does not support interactions It allows the users to freely interact with each other It includes informational portal as a prime capability and feature It includes information sharing, interaction , participation and collaboration as prime capabilities Example: Personal web sites Example: YouTube, Facebook, blogs[6] Cloud Computing Gartner has highlighted a number of myths that are associated with cloud computing. Out of the 10 myths that have been covered, one of them same that cloud is always about money. This is necessarily a myth as there are a number of services and platforms that are present over cloud for negligible price or even free of cost. There are multiple cloud based databases that can be downloaded and used for free. The money that is involved with cloud depends upon a lot many factors such as type of service required, aim of the service, primary goals, platform to be used and many others. Thus, this is rightly a myth and the money around the concept should never be taken for granted. References Cormode, G. and Krishnamurthy, B. (2008). Key differences between Web 1.0 and Web 2.0.

E.B. White's Prophetic 1948 Essay That Anticipated 9/11 In the first paragraph, drawn from the opening of Here Is New York, E.B. White approaches the city through a simple pattern of classification. In the next two paragraphs, taken from the end of the essay, White hauntingly anticipates the terror that would visit the city more than 50 years later. Notice Whites habit of putting keywords in the most emphatic spot in a sentence: the very end. This is an excerpt from Whites piece on New York first published in 1948.  Here Is New York also appears in Essays of E.B. White (1977). Here Is New York There are roughly three New Yorks. There is, first, the New York of the man or woman who was born there, who takes the city for granted and accepts its size, its turbulence as natural and inevitable. Second, there is the New York of the commuter - the city that is devoured by locusts each day and spat out each night. Third, there is New York of the person who was born somewhere else and came to New York in quest of something. Of these trembling cities, the greatest is the last - the city of final destination, the city that is a goal. It is this third city that accounts for New York’s high strung disposition, its poetical deportment, its dedication to the arts, and its incomparable achievements. Commuters give the city its tidal restlessness, natives give it solidity and continuity, but the settlers give it passion. Whether it is a farmer arriving from a small town in Mississippi to escape the indignity of being observed by her neighbors, or a boy arriving from the Corn Belt with a manuscript in his suitcase and a pain in his heart, it makes no difference. Each embraces New York with the intense excitement of first love, and each absorbs New York with the fresh eyes of an adventurer, each generates heat and light to dwarf the Consolidated Edison Company. The city, for the first time in its long history, is destructible. A single flight of planes no bigger than a wedge of geese can quickly end this island fantasy, burn the towers, crumble the bridges, turn the underground passages into lethal chambers, cremate the millions. The intimation of mortality is part of New York now; in the sounds of jets overhead, in the black headlines of the latest editions. All dwellers in cities must live with the stubborn fact of annihilation; in New York, the fact is somewhat more concentrated because of the concentration of the city itself, and because, of all targets, New York has a certain clear priority. In the mind of whatever perverted dreamer might loose the lightning, New York must hold a steady, irresistible charm. Selected Works by E.B.

The Roles of sport in Jamaica essays

The Roles of sport in Jamaica essays Jamaica has had more success, per year, in international track and field competition, than any other country. In our 1948 Olympic debut, Dr. Arthur Wint won our first Olympic and gold medal in the 400m. He along with the other members of the legendary relay team, Herb McKenley, Leslie Laing, and George Rhoden (gold medalists, 1952), set a standard that has been upheld by our athletes ever since. From Donald Quarrie (gold 200m, silver 100m, 1976) to David Weller (bronze cyclying, 1980) to Andrew Phillips (6th, 200m swimming medley, 1984) to Bert Cameron (silver, 400 relay, 1988), to Grace Jackson (silver, 200m, 1988), to Winthrop Graham (silver, 400m hurdles, 1992), Raymond Stewart, Juliet Cuthbert (silver, 100, 200m, 1992), Deon Hemmings (gold, 400 hurdles, 1996) and to the seemingly eternal queen of track, Merlene Ottey who has won more Olympic and IAAA medals than any other Jamaican. Most athletes began their careers at school track meets. The National Boys and Girls Championship (Champs') is a premier event for the high scholars and many past students who vigorously support their alma maters. The high standard of competition has made Champs' the first stop on the overseas college recruiting circuit. The Penn Relays High School Division could be called the Jamaica Relays because our youngsters dominate the field. Jamaican teams have, on several occasions, taken the top 3 positions in the 4x400 relays for high school boys. Some major sports that is still in Jamaica history are the following: cricket, we have been made proud by the achievements of George Headley, Michael Holding, Courtney Walsh, Jeffrey Dujon, Lawrence Rowe, Allan Rae, Maurice Foster, Jimmy Adams, Robert Samuels. Next was Football our torch was carried abroad by Lindy Delapenha, the first Jamaican to play in the English Premier League. Others like John Barnes (England/Newcastle) serve as inspiration to schoolboys participating in the fiercely contested DaCosta and M...

Corporate Social Responsibility Essay Example | Topics and Well Written Essays - 750 words

Corporate Social Responsibility - Essay Example In order to evaluate the CSR of multinational companies, some quality assurance organizations conduct surveys and determine which companies are most ethical in terms of doing businesses. Recently, on March 2012, Forbes released a list of most ethical companies of the world. In this paper, ethical evaluation of a large multinational business of hospitality industry has been provided which is Marriot International Hotels. Categories of CSR For CSR, companies are generally categorized in the three main categories. They include 1. Neutral CSR This category describes that companies possess neutral characteristics for practicing CSR obligations. Companies operating under this head are obliged for not lying, stealing or cheating, adhering to economic activities etc. A large number of companies fall under this category. 2. Negative CSR CSR Negative states that some companies for a certain period of time break the legal laws and act in negative ways. These practices often put the welfare of s ociety at stake. A recent example of such organization is British Petroleum. The case of oil spill of BP caused great danger to the environment and also ruptured the image of the company. 3. Positive CSR This category includes all those companies which satisfies a large number of stakeholders just like Marriot International. ... Marriot International Hotels have made profound progress in areas such as environmental and social, economic and sustainability.

Human Computer Interaction Assignment Example | Topics and Well Written Essays - 750 words

Human Computer Interaction - Assignment Example As society is growing increasingly attached and setting strong footing on a knowledge-based economy, there are excellent opportunities for people with disability to participate fully in the economic and social life of their communities. The realization of this scenario depends on what takes place to people with disabilities in using the new information technology systems and computers. Ensuring that the concerns and needs of students with all types of disability are well represented in planning. Joe is a professional peer counselor and motivational speaker. He is in his early 20’s and has attended college where he recently completed a diploma in Peer counseling and guidance. Joe is not able to us his eye sight since he is visually impaired and has actually attended a college that was catering for his sight needs. Joe is not yet a family man and volunteers in the local Nongovernmental Organization for the disabled and physically handicapped. He majorly plays the big brother role of encouraging the others and showing them that there is a cause to live for and that disability is not inability. The disability to be used in this scenario is visual disability. Individuals who have low vision, blind or have color blindness are referred to as visually impaired. Blind people need equivalents of text for the images on the website pages, since the screen reader technology that helps them cannot obtain information from images. Visually impaired persons may not find the mouse very useful since it requires eye and hand coordination. In place of the two they must navigate the website page using only the keyboard. For instance, the tab key moves the focus to the next item that a user needs to select. A screen reader announces the item name so that the user knows what to select and where to put focus on the page. The user will then hit the Enter key instead of using a mouse button.

Cache Memory: Definition and Function

Cache Memory: Definition and Function CACHE MEMORY Cache memory is random access memory (RAM) that a pc micro chip will access a lot of quickly than it will access regular RAM. because the micro chip processes knowledge, its initial within the cache memory and if it finds the information there (from a previous reading of data), it doesnt got to do the a lot of long reading of knowledge from larger memory. Cache memory is usually delineate in levels of closeness and accessibility to the micro chip. associate L1 cache is on identical chip because the micro chip. L2 is typically a separate static RAM (SRAM) chip. the most RAM is typically a dynamic RAM (DRAM) chip. In addition to cache memory, one will think about RAM itself as a cache of memory for disc storage since all of RAMs contents return from the disc at the start. once the processor has to scan from or write to a location in main memory, it initial checks whether or not a duplicate of that knowledge is within the cache. If so, the processor straightaway reads from or writes to the cache, that is far quicker than reading from or writing to main memory. a translation look aside buffer (TLB) wont to speed up virtual-to-physical address translation for each practicable directions and knowledge. Knowledge is transferred between memory and cache in blocks of mounted size, known as cache lines. once a cache line is derived from memory into the cache, a cache entry is made. The cache entry can embody the derived knowledge in addition because the requested memory location currently known as a tag. once the processor has to scan or write a location in main memory, it initial checks for a corresponding entry within the cache. The cache checks for the contents of the requested memory location in any cache lines that may contain that address. If the processor finds that the memory location is within the cache, a cache hit has occurred. WRITE POLICY: If knowledge is written to the cache, at some purpose it should even be written to main memory. A write policy determines however the cache deals with a write cycle. The 2 common write  policies area unit Write-Back and Write-Through. WRITE BACK POLICY In Write-Back policy, the cache acts sort of a buffer. That is, once the processor starts a write cycle the cache receives the information and terminates the cycle. The cache then writes the information back to main memory once the system bus is offered. This technique provides the best  performance by permitting the processor to continue its tasks whereas main memory is updated at a  later time. However, dominant writes to main memory increase the cache’s quality and  cost. WRITE THROUGH POLICY The second technique is that the Write-Through policy. because the name implies, the processor writes through the cache to main memory. The cache could update its contents, but the write cycle doesnt finish till the information is keep into main memory. This technique is a smaller amount advanced. The primary drawback with write-through caches is their higher write traffic as compared to write-back caches. a method to scale back this traffic is to use a coalescing write buffer, wherever writes to addresses already within the write buffer area unit combined. once a write misses within the write cache, the LRU entry is transferred to the write buffer to create area for the present write. In actual implementation, the write cache may be integrated with a coalescing write buffer. Write through policy is most prefererable in memory application than write back policy as a result of it embody the property of automatic update once any changes occur in cache block itll replicate into main memory. CONVENTIONAL 2 LEVEL CACHE Fig. 3illustrates the design of the two-level cache. solely the L1 knowledge cache and L2 unified cache area unit shown because the L1 instruction cache solely reads from the L2 cache. below the write through policy, the L2 cache continuously maintains the foremost recent copy of the information. Thus, whenever a knowledge is updated within the L1 cache, the L2 cache is updated with identical knowledge in addition. This ends up in a rise within the write accesses to the L2 cache and consequently a lot of energy consumption. The locations (i. e. , approach tags) of L1 knowledge copies within the L2 cache wont modification till the information area unit evicted from the L2 cache. The planned way-tagged cache exploits this reality to scale back the quantity of the way accessed throughout L2 cache accesses. once the L1 knowledge cache masses a knowledge from the L2 cache, the approach tag of the information within the L2 cache is additionally sent  to the L1 cache and keep during a new set of approach-tag arrays These way tags give the key data for the following write accesses to the L2 cache. In general, each write and browse accesses within the L1 cache may have to access the L2 cache. These accesses result in totally different operations within the planned way-tagged cache, as summarized in Table I. below the write-through policy, all write operations of the L1 cache got to access the L2 cache. within the case of a write hit within the L1 cache, only 1 approach within the L2 cache are going to be activated as a result of the approach tag data of the L2 cache is offered, i. e. , from the approach-tag arrays we are able to acquire the L2 way of the accessed knowledge. whereas for a write miss within the L1 cache, the requested knowledge isnt keep within the L1 cache. As a result, its corresponding L2 approach data isnt offered within the way-tag arrays. Therefore, all ways that within the L2 cache got to be activated at the same time. Since write hit/miss isnt proverbial a priori, the way-tag arrays got to be accessed at the same time with all L1 write operations so as to avoid performance degradation. Note that the way-tag arrays area unit terribly little and also the concerned energy overhead may be simply salaried for (see section). For L1 scan operations, neither scan hits nor misses got to access the way-tag arrays. this is often as a result of scan hits dont got to access the L2 cache; whereas for scan misses, the corresponding approach tag data isnt offered within the way-tag arrays. As a result, all ways that within the L2 cache area unit activated at the same time below scan misses. PROPOSED approach TAG CACHE we tend to introduce many new components: way-tag arrays, way-tag buffer, approach decoder, and approach register, all shown within the line. The approach tags of every cache line within the L2 cache area unit maintained within the way-tag arrays, set with the L1 knowledge cache. Note that write buffers area unit normally used in write through caches (and even in several write-back caches) to boost the performance. With a write buffer, the information to be written into the L1 cache is additionally sent to the write buffer. The operations keep within the write buffer area unit then sent to the L2 cache in sequence. This avoids write stalls once the processor waits for write operations to be completed within the L2 cache. within the planned technique, we tend to conjointly got to send the approach tags keep within the way-tag arrays to the L2 cache at the side of the operations within the write buffer. Thus, alittle approach-tag buffer is introduced to buffer the way tags scan from th e way-tag arrays. {a approach|how|some way|the way|the simplest way} rewriter is used to decode way tags and generate the alter signals for the L2 cache, that activate solely the specified ways that within the L2 cache. every approach within the L2 cache is encoded into the simplest way tag. {a approach|how|some way|the way|the simplest way} register stores way tags and provides this data to the way-tag arrays. IMPLEMENTATION OF WAY-TAGGED CACHE WAY-TAG ARRAYS Way tag arrays have approach tags of a knowledge is loaded from the L2 cache to the L1 cache, shown in Fig three. Note that {the knowledge|the info|the information} arrays within the L1 data cache and also the way-tag arrays share identical address from hardware. The WRITEH_W signal of way-tag arrays is generated from the write/read signal of {the knowledge|the info|the information} arrays within the L1 data cache as shown in Fig. 8. A UPDATE is management signal, obtained from the cache controller. once a L1 write miss, UPDATE are going to be declared and permit WRITEH_W to alter the write operation to the way-tag arrays (UPDATE=1 and WRITEH_W, See Table II). UPDATE keeps invalid and WRITEH_W =1, a scan operation to the way-tag arrays. During the scan operations of the L1 cache, the way-tag arrays dont got to be accessed and so, scale back energy overhead. to attenuate the overhead of approach tag arrays, the scale of a way-tag array may be expressed as Where SL1, Sline,L1 and Nway,L1 area unit the scale of the L1 knowledge cache, cache line size and variety of the ways that within the L1data cache severally. Bway,L2= may be a code. The way-tag arrays area unit operated in parallel with the L1 knowledge cache for avoiding the performance degradation. as a result of their little size, the access delay is far smaller than that of the L1 cache. WAY-TAG BUFFER Way-tag buffer is quickly stores the approach tags from the way-tag arrays within the L1 cache. its identical variety of entries because the write buffer of the L2 cache and shares the management signals with it. Note that write buffers area unit normally used, the information to be written into the L1 cache is additionally sent to the write buffer to boost the performance. This avoids write stalls once the processor waits for write operations to be completed within the L2 cache. When a write miss happens in L1 cache, all the ways that within the L2 cache got to be activated because the approach data isnt offered. Otherwise, solely the specified approach is activated. approach tag buffer is little in to avoid space overhead. Approach DECODER The operate of the approach rewriter is used to decode approach tags and generate the alter signal, that activate solely desired ways that in L2 cache. This avoids the extra wires and also the chip space is negligible. A write hit within the L1 cache, the approach decoder works as associate n -to- N decoder that selects one way-enable signal. For a write miss or a scan miss within the L1 cache, the approach decoder assert all way-enable signals, in order that all ways that within the L2 cache area unit activated. Approach REGISTER The approach tags for the way-tag arrays is Provided by approach register. A 4-way L2 cache is take into account, that labels â€Å"00†, â€Å"01†, â€Å"10†, andâ€Å"11†. This area unit keep within the approach register. once the L1 cache masses a knowledge from the L2 cache, the corresponding approach tag within the approach register is distributed to the approach-tag arrays by this way the corresponding way tags area unit keep in way-tag array. The planned approach-tagged caches way operates below totally different modes throughout scan and write operations. solely the approach containing the specified knowledge is activated within the L2 cache for a write hit within the L1 cache, operating the L2 cache equivalently a direct-mapping cache to scale back energy consumption while not performance overhead below the write-through policy. APPLICATION OF approach TAGGING IN PHASED ACCESS CACHES In this section, we are going to show that the thought of approach tagging may be extended to alternative low-power cache style techniques suchas the phased access cache [18]. Note that since the processor performance is a smaller amount sensitive to the latency of L2 caches, several processors use phased accesses of tag and knowledge arrays in L2 caches to scale back energy consumption. By applying the thought of approach tagging, any energy reduction may be achieved while not introducing performance degradation. In phased caches, all {ways|ways that|ways in that} within the cache tag arrays got to be activated to work out which approach within the knowledge arrays contains the specified knowledge (as shown within the solid-line a part of Fig. 8). within the past, the energy consumption of cache tag arrays has been unnoticed as a result of their comparatively little sizes As superior microprocessors begin to utilize longer addresses, cache tag arrays become larger. Also, high associativity is vital for L2 caches in bound applications. These factors result in the upper energy consumption in accessing cache tag arrays. Therefore, its become vital to scale back the energy consumption of cache tag arrays. the thought of approach tagging may be applied to the tag arrays of phased access cache used as a L2 cache. Note that the tag arrays dont got to be accessed for a write hit within the L1 cache (as shown within the dotted-line half in Fig. 9). {this is|this is often|this may be} as a result of the destination approach of knowledge arrays can be determined directly from the output of the approach decoder shown in Fig. 7. Thus, by accessing fewer ways that within the cache tag arrays, the energy consumption of phased access caches may be any reduced The operation of this cache is summarized in Fig. 9. Multiplexor M1 is used to get the alter signal for the tag arrays of the L2 cache. once the standing bit within the way-tag buffer indicates a write hit, M1 outputs â€Å"0† to disable all the ways that within the tag arrays. As mentioned before, the destination approach of the access may be obtained from the approach decoder and so no tag comparison is required during this case. Multiplexor money supply chooses the output from the approach decoder because the choice signal for the information arrays. If on the opposite hand the access is caused by a write miss or a scan miss from the L1 cache, all ways that area unit enabled by the tag array decoder, and also the results of tag comparison is chosen by money supply because the choice signal for the information arrays. Overall, fewer ways that within the tag arrays area unit activated, thereby reducing the energy consumption of the phased access cache. Note that the phased ac cess cache divides associate access into 2 phases; so, money supply isnt on the crucial path. Applying approach tagging doesnt introduce performance overhead as compared with the standard phased cache. Common or Shared LUT design A shared or common LUT design is planned to be applied in knowledge array management of this cache design. Since knowledge array in cache design is related to electronic device choice based mostly processor for knowledge accessing, we tend to area unit introducing associate shared LUT during which all knowledge data is loaded with table loader per is index and coefficients for knowledge finding and matching allocation throughout cache operations. thus knowledge array may be replaced by shared LUT design with effectively acts and reduces the whole power consumption of overall approach tag array cache design. From the fig. 7. the shared LUT design is divided in to four banks with several address related to it. If a processor has to access knowledge from bank three, itll directly access that data via its constant bit address by matching with table loader indexes. Hence a protracted looking method is proscribed to direct accessing technique through shared LUT design. Apart from banks it conjointly has SFU-Special practical Units in it. its connected to table loader. These SFU’s will access all the banks by having easy indexes like â€Å"000† the primary zero represents the quantity of SFU i. e SFU 0. thus the remainder 2 zero’s represents the bank constant. By bit matching, SFU simply connects with bank zero that contain relevant knowledge access in cache operations. If SFU0 and SFU one having values like â€Å"000† and â€Å"100† then confusion is cleared by higher priority portal. the upper priority is nothing however one that comes initial is allowed to access the information initial too. the remainder request signals accessed in  Ã‚  parallel at that time.

Monroe Clock Company

Assignment #1 The problem that is brought to our attention would be an argument between Monroe Company executives. Jim, the Ceo, believes that the product should use plant wide manufacturing overhead, which brings the retail sale of the product to $29. 40/per unit. Meanwhile frank, the Sale Manager, believes the product should not absorb the entire manufacturing overhead and be based off the variable cost it incurs and sold at $16. 00/per unit.The issue occurs when deciding whether to choose between variable costing, not including fixed cost, which is usually acceptable on small orders, or choosing absorption costing which includes a portion of the fixed costs. Of course choosing between the two different costing approaches makes a big difference in this case. One keeps the product above market price while the other cuts the competitors prices by 20%. With out thinking you would go with cutting competitors prices and still gaining sales.What to keep in mind is using the variable cost ing approach you aren’t accounting for the manufacturing overhead that the new timer is incurring. It is possible that the new timer isn’t incurring much overhead considering it is simply a new addition to the old timer. The modifications to create the new addition are simple and at low cost because the resources are already there. They did not have to create or purchase a new warehouse because they already had recently purchased one and were going to use it regardless.Other than the initial set up cost of approximately $20000 for tables, lighting and small tools, the other overhead cost would already be accounted for and the new incurred overhead cost would not go beyond the relevant range of fixed cost.. One thing not accounted for in the calculations is the location of the new warehouse. There will clearly be transportation cost because one warehouse is in Texas and the other in Pennsylvania.Of course we don’t know which warehouse will be used but still a cos t to consider. With the new timer absorbing the full manufacturing overhead cost it would of course increase the price of the product almost doubling it but does not run the risk of creating a product that actually has them loosing money in the long run. The variable costing approach of course will create sales and revenue in the short run but in the long run can possibly create losses by not accounting for all the cost actually incurred.My conclusion (due to space restriction) would be to use the variable costing approach due to everything mentioned and one more determining factor. The forecasted sales projection is 50 000 units. At this production level advertising would be $50 000 regardless of how many units they sale. By using the cheaper pricing you are creating a better chance of you getting those sales and after you sell a unit past 50 000 you will be creating more profit because the budget of sales, which is $1. 00 per unit, would be divided among more units.
