Information and communication technology plays an important role in addressing the world’s energy problem. Networked digital electricity meters (so-called smart meters), for instance, can provide households with real-time information on their electricity consumption and thus help them to conserve energy. Initial expectations on the saving potential of this technology were too optimistic, howeve...

We investigate power consumption of a mobile station with the power saving class of type 1 in the IEEE 802.16e. We deal with stochastic behavior of mobile station during not only sleep mode period but also awake mode period with both downlink and uplink traffics. Our methods for investigating the power saving class of type 1 are to construct the embedded Markov chain and the semi-Markov chain g...

As the workhorse of consumption and saving research for the past four decades, the life-cycle model has proved flexible and useful for examining a variety of questions. In a classic paper, Albert Ando and Franco Modigliani (1963 p. 56) stated a key assumption of the basic model: "[tlhe individual neither expects to receive nor desires to leave any inheritance." Although the authors contended th...

This paper offers an overview of the links between risk and consumption that are discussed in the theoretical literature and the empirical support these theories have received. In the theoretical literature we find two mechanisms whereby risk affects consumption. The first is precautionary saving. Greater risk regarding future income may lead to increased saving to create a buffer against poten...

Building energy consumption monitoring and management system plays a vital role in the advance of building energy conservation, because it offers abundant online real time data, which are mainly used to further analyze energy saving potential and put forward a feasibility methodology for implementation. In addition to its extreme importance in decreasing energy consumption and saving costs, the...

In order to reduce energy consumption of data centers while employing infrastructure resource effectively, a comprehensive resource management method using an improved online energy saving mapping algorithm for virtual machines of data centers is proposed. An intelligent feedback management framework is built for online resource optimization. We propose reinforcement learning and threshold base...

Saving of energy and time in drying of laundry directly depends upon the residual water content of the fabric at the end of the spinning cycle. If the amount of water left in the fabric is significantly reduced then the time and energy required to dry the fabric is less. Both these factors benefit the consumer and the national energy consumption. For the USA alone, the 30 % reduction in the res...

Energy consumption in caches is widely studied topic. The access to a cache line consumes energy. This paper proposes exclusive cache model that reduces the energy consumption over the tag cache model. The proposed model assumes two level exclusive cache with tag cache in level one. The tag cache consists of tag information of all cache levels. It is stored in cache in level one. An address is ...

Wireless sensor networks(WSNs) consists of a large number of wireless sensor nodes that have sensing, data processing and communication functionalities. WNSs are typically used to monitor a field of interest to detect movement, temperature changes, precipitation etc. Energy Consumption and Coverage are two major problems in wireless sensor networks. We implement our proposed scheme in NS-2 as a...

This paper examines how aversion to risk and aversion to intertemporal substitution determine the strength of the precautionary saving motive in a two-period model with Selden/Kreps-Porteus preferences. For small risks, we derive a measure of the strength of the precautionary saving motive which generalizes the concept of "prudence" introduced by Kimball (1990b). For large risks, we show that d...
