Train energy saving problem investigates how to control train's velocity such that the quantity of energy consumption is minimized and some system constraints are satis ed. On the assumption that the train's weights on different links are estimated by fuzzy variables when making the train scheduling strategy, we study the fuzzy train energy saving problem. First, we propose a fuzzy energy ...

This paper considers a two period consumption-saving model in which future income is uncertain. If the future income is also ambiguous, in the sense of having multiple priors, then ambiguity attitudes also a¤ect the saving decision. Unlike one-period decision problems, ambiguity attitude does more than just distort the probabilities of the various priors. It also distorts the relative importanc...

We develop and test a simple model of limited attention in intertemporal choice. The model posits that individuals fully attend to consumption in all periods but fail to attend to some future lumpy expenditure opportunities. This asymmetry generates some predictions that overlap with models of present-bias. Our model also generates the unique predictions that reminders may increase saving, and ...

839 All Rights Reserved © 2013 IJARCET Abstract Wireless hosts are usually powered by batteries which provide a limited amount of energy. Therefore, techniques to reduce energy consumption are of interest. One way to conserve energy is to use power saving mechanisms. Power saving mechanisms allow a node to enter a doze state by powering off its wireless network interface when deemed reasonable....

A power-saving management for OLTP applications has become an important task for user budgets and datacenter operations. This paper presents a novel power-saving method for multiple disk drives based on knowledge of OLTP application behaviors. We report detail analysis of power consumption of disk drives and I/O characteristics of OLTP application. We then show experimental and simulation resul...

We observe that the state-of-the-art power-saving mechanisms (PSM) for IEEE 802.16e is neither optimal in terms of delay nor in terms of energy consumption. We propose a new PSM which achieves the optimality in terms of the average buffering delay without increasing energy consumption. In order to do so, we derive a formula which relates the average buffering delay to sleep intervals. Simulatio...

With each CMOS technology generation, leakage energy has been increasing at an exponential rate. Since modern processors employ large last level caches (LLCs), their leakage energy consumption has become an important concern in modern chip design. To address this issue, several techniques have been proposed. However, most of these techniques require offline profiling and hence, cannot be used i...

Poor families around the world spend a large fraction of their income on consumption of goods that appear to be useless in alleviating poverty, while saving at very low rates and neglecting investment in health and education. Such consumption patterns seem to be related to the persistence of poverty. We offer an explanation for this observation, based on a trade-off between conspicuous consumpt...
