This paper is concerned with the theory of saving when consumers are not permitted to borrow, and with the ability of such a theory to account for some of the stylized facts of saving behavior. When consumers are relatively impatient, and when labor income is independently and identically distributed over time, assets act like a buffer stock, protecting consumption against bad draws of income. ...

High battery lifetime is important to the usabil-ity and acceptance of portable computers. In order to develop strategies to minimize power consumption , designers need a good picture of the total power consumption of a system. For this purpose , we indicate the power consumptions of a set of portable computers and how they are broken down among the components of those computers. Then, we use u...

Sustainable architecture is known as an important strategy in recent years and all around the world are cooperating to achieve this by use of natural elements. There are many examples of residential buildings in Iran s past and its traditional architecture that the architecture in the interim of paying attention to aesthetic issues and preserving the natural environment acts in a way that meets...

Predictors are used in many subfields of computer architecture to enhance performance. Accurate estimations of future system behavior allow to develop policies to improve system performance or reduce power consumption. These policies become more efficient if predictors are implemented in hardware and are able to provide quantified forecasts, i.e. providing more than binary forecasts. One of the...

Energy crisis, global warming and other environmental issues are what motivate researchers to find new strategies to reduce energy consumption in buildings. Recently, using phase change materials (PCM) in the building’s envelopes has drawn significant attention as an energy-saving method, which helps in increasing the building’s thermal capacity. In the present research, the effects of the ...

What role does the fourth retirement pillar of home ownership and private saving play in rich nations? Does this asset-based welfare spread the risks of retirement provision or does it distort consumption patterns and fail to improve the non-housing consumption of the elderly? Is it associated with more or less inequality of retirement consumption? This paper examines the role of home ownership...

In an effort to reduce the energy consumption of high performance computing centers, a number of new approaches have been developed in the last few years. One of these approaches is to switch hardware to lower power states in promising parallel application phases. A test cluster is designed with high performance computing nodes supporting multiple power saving mechanisms comparable to mobile de...
