Power consumption of modern datacenters is increasing rapidly. Databases, especially OLTPs, have become a major application at datacenters. Therefore, power-saving management for OLTP applications has become an important task for user budgets and datacenter operations. A recent report described that disk drives consume about 70% of total power of IT equipment when such large OLTP applications a...
For some people, social status seems to be a factor in saving electricity power. The aim of this study was to develop and validate an electricity-saving scale based on social status upgrading. In conducting this study, using the relevant theories, the scale was prepared. For investigating validity and reliability the opinion of experts, exploratory and confirmatory factor analysis, and Cronbach...
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...
In current scenario, there is a requirement of power saving in multimedia devices such as mobile and televisions. When we increase contrast in these devices, more power to be consumed by display panel. The PCCE algorithm has been developed a framework for power saving and contrast enhancement together in emissive displays. But this algorithm does not give proper results on noisy image due to un...
In IEEE 802.16, a Subscriber Station (SS) is battery powered with limited capacity. A SS can be made to operate for longer durations by deploying power saving features or by using relay stations. Multi-hop communication conserves power, but finding an optimal path to the destination is monotonous. Path stability indicates how stable a path is and how long it can support communication. Identifyi...
The design of a broadband cellular network demands powerful modulation and coding under the tight constraints of affordable modem complexity and low power consumption for the mobile terminal (MT). In order to increase battery life and allow low-cost mobile equipment to be effectively integrated in such a broadband system we propose the use of a low-rate separate signaling channel (SSC) on the p...
In this paper, we propose a protocol for routing in Bluetooth scatternets. The protocol uses the available battery power in the Bluetooth (BT) devices as a cost metric in choosing the routes. We evaluate the throughput performance as a function of packet arrival rate and number of piconets. A throughput of about 120 Kbps/piconet is shown to be achieved in a 5piconet scatternet. We propose two t...
this paper describes a study that starts with an analysis of typical energy demand profiles in a hospital setting followed by a case study of a combined cooling, heating, and power (cchp) generation system.cchp is an autonomous system that combines the generation of electrical, heating, and cooling energy.the driving units are two high-efficiency gas engines that produce electrical and heat ene...
Due to the increasing interest on renewable sources in recent years, the studies on integration of distributed generation to the power grid have rapidly increased. In order to minimize line losses of power systems, it is crucially important to define the size and location of local generation to be placed. Minimizing the losses in the system would bring two types of saving, in real life, one is ...
