ABSTRACT For complete control of the building, a proper SCADA implementation and the optimization strategy has to be build. For better communication and efficiency a proper channel between the Communication protocol and SCADA has to be designed. This paper concentrate mainly between the communication protocol, and the SCADA implementation, for a better optimization and energy savings is derived to large scale industrial buildings. The communication channel used in order to completely control the building remotely from a distant place. For an efficient result we consider the temperature values and the power ratings of the equipment so that while controlling the equipment, we are setting a threshold values for FDD technique implementation. Building management system became a vital source for any building to maintain it and for safety purpose. Smart buildings, refers to various distinct features, where the complete automation system, office building controls, data center controls. ELC's are used to communicate the load values of the building to the remote server from a far location with the help of an Ethernet communication channel. Based on the demand fluctuation and the peak voltage, the loads operate differently increasing the consumption rate thus results in the increase in the annual consumption bill. In modern days, saving energy and reducing the consumption bill is most essential for any building for a better and long operation. The equipment - monitored regularly and optimization strategy is implemented for cost reduction automation system. Thus results in the reduction of annual cost reduction and load lifetime increase.

In any business environment companies experience challenges and competition. In this current worldwide economic crisis, the stakes are now higher. With every crisis comes opportunity. The best companies with the best methods and processes that create highest quality product for less money will have an extraordinary advantage over their less efficient, lower quality competition. The term ‘Lean’ describes how Toyota does business: fewer humans, less effort, less investment, fewer defects, less time to develop, less inventory. For companies that have truly understood and implemented these principles the effects are significant; but many others have failed Lean initiatives. What factors are necessary for a company to successfully adopt the processes proven by over 50 years of success in Toyota? Using both primary and secondary research, I compared attributes of four companies, three of which were successful, and one that did not make the conversion. Three main factors emerged, the Technical Factor -- knowing both your core business and having a deep understanding of Lean principles, the Management Factor -- strong leadership operating within Lean principles and with hands-on approach, and the Human Factor -- approaching the workforce with respect and employee engagement in problem-solving process. The following is a brief review of these factors and the tools and concepts that undergird them. / text

This dissertation consists of three essays on income risk and aggregate demand over the business cycle, each addressing an aspect of the Great Recession. The first chapter reframes the standard liquidity trap model to illustrate the costly feedback loop between idiosyncratic risk and aggregate demand. I first show that a liquidity trap can result from excess demand for precautionary savings in times of high uncertainty. Second, I show that the output and welfare costs of the ensuing recession depend crucially on how the drop in demand for output is translated into a reduction in demand for labor. Increased unemployment risk compounds the original rise in idiosyncratic productivity risk and reinforces precautionary motives, deepening the recession. Third, I show that increasing social insurance can raise output and welfare at the zero bound. I decompose these effects to distinguish the component unique to the liquidity trap environment and show that social insurance is most effective at the zero bound when it targets the type of idiosyncratic risk households face, which in turns depends on the labor market adjustment mechanism. The second paper offers a novel model of the connection between the consumer credit and home mortgage markets through an individual’s credit history. This paper introduces a novel justification for the home mortgage interest deduction. In an economy with both housing assets and consumer credit, the mortgage interest deduction is modeled as a subsidy for the accumulation of collateralizable assets by households who have maintained good credit. As such, the subsidy loosens participation constraints and facilitates risk-sharing. Empirical evidence and a calibration exercise reveal that the subsidy has a sizable impact on the availability of credit. The third paper assesses the role of policy uncertainty in the Great Recession. The Great Recession features substantial geographic variation in employment losses, a fact that is often presented as a challenge to uncertainty-based models of the downturn. In this paper we show that there is a substantial correlation between the distribution of employment losses and the increases in local measures of both economic and policy uncertainty. This relationship is robust across a wide range of measures. / Economics

The rebound effect refers to the phenomenon that energy savings from improvements in energy efficiency are lower than expected due to unintended second-order effects. Grasping specific mechanisms related to the rebound effect requires a good understanding of interactions between heterogonous agents on multiple markets. Otherwise, policies aimed at reducing energy use may render counter-expected and unforeseen consequences. In this paper, we propose a formal model, where technological change results from interactions on two markets: between consumers and producers in the market for final goods, and heterogeneous power plants in the electricity market. The analysis provides insights to the role of technological change, supply-demand coevolution, and status-driven consumption in explaining the rebound effect. The model is employed to compare effectiveness of economic policies aimed at reducing carbon emissions associated with production of consumer goods, namely: a tax on electricity and "nuclear obligations" to produce ten percent of electricity from nuclear energy.

This work is part of a broader, multi-year investigation of Maui Island’s freshwater resources. Maui Island faces multiple resource constraints, including water, land, energy, and capital, and these resource constraints could become relevant over the next forty years. Not only does Maui face potential changes to its water and other systems due to external factors beyond its control, like anthropogenic and other climate changes, but Maui also could make developmental choices that will impact how its resource systems interact. In particular, this work looks at Maui’s freshwater systems as they relate to energy, waste, and environmental systems. This report provides a foundation for future scenario analysis on the island that will aim to characterize potential synergies and hazards of choices like increased food production, local fuel production, and increased use of renewable energies. / text

The use of Kinetic Hydrate Inhibitors (KHI) is one of the optimum methods employed to control gas hydrate formation issues and provide flow assurance in oil and gas production systems. The application of this technology has several advantages to operators, including significant cost savings and extended life of oil and gas systems. This paper will highlight a specific case where a Major operator in the North Sea (UK sector) significantly reduced the cost of well intervention operations by applying a KHI in a subsea gas lift line. Considerable cost savings were realized by reducing volume of chemical required and this enabled the application to be performed from the FPSO eliminating the need for a dedicated Diving Support Vessel (DSV). Furthermore, the application of KHI also reduced manual handling and chemical logistics usually associated with this particular treatment. In order to prevent mineral scale deposition occurring in downhole tubing and near well bore and in the formation; scale inhibitor squeeze applications are standard practice. For subsea wells the fluids can be pumped down in to the well via gas lift lines. However, upon completion of previous scale squeeze operations at this particular location, hydrate formation was observed when a mixture of MEG and water was used following interventions via the gas lift line. By applying 1% KHI with a mixture of MEG and Water, the well was brought back into production following scale squeeze operations without hydrate formation occurring.

This thesis utilises the second fundamental law of capitalism in order to study the development of income inequality in Sweden, from the start of the 19th century to the beginning of the 21stcentury. The law is studied from a historical perspective (examination of national accounts as time series), and empirically analysed (regression analysis). The results retrieved indicate that the income diverging force of savings exceed the income converging force of growth (via income, innovation, and education). This means that income inequality is predicted to increase. The main conclusion drawn is that choosing whether to save or not on behalf of every individual affects the capital stock of the aggregate economy. When individual savings pile up the aggregate capital stock increases, and if this increase surpasses the growth in national income the capital-to-income ratio increases. This ratio is in a sense a measure of how capitalistic the country is. More income inequality is expected to be found the higher this ratio gets.

Pensionen är en viktig del av en individs framtida liv som mycket väl kan innebära skillnaden mellan ett lyckligt eller miserabelt liv som pensionerad. I vardagen kan vi höra om pensionen och var vi bör vända oss, vare sig det gäller media, affischer eller annan reklam, men vet vi tillräckligt för att kunna pensionsplanera? Denna kvantitativa studie använder sig av data från en norsk enkätundersökning på internet, för att ta reda på vilka faktorer som kan påverka individers pensionsplanering i form av privat sparande. Studien lyckas bekräfta en positiv relation mellan privat sparande och fyra variabler; årsinkomst, åldersgrupp, tankar kring pension samt sysselsättning. / The pension is an important part of an individual’s future life which could very well be the difference between a happy or a miserable life as a retired individual. In everyday life we hear about retirement and where we should turn, whether it is media, posters or other advertising, but do we know enough to be able to forge a retirement plan? This quantitative study uses data from a Norwegian internet based survey, to find out what factors can influence individuals’ retirement planning in the form of private savings. The study succeeds confirm a positive relationship between private saving and four variables; annual income, age cohort, thoughts on retirement and employment.
