Motivated by both cost savings and environmental concerns, managing energy in the home has become increasingly important. Though both user-driven and automated solutions have shown promise, a deeper understanding of the characteristics of energy usage behavior is necessary to inform the design of such systems. In this work, we present the results of a study that explores the insights and charac...

In this work, a three-node, two-way relaying network (TWRN) over a multi-carrier system is considered. The aim is to minimize total energy usage of such a multi-carrier TWRN with the constraint of rate requirements on both sides, with both the transmit energy usage as well as the receive energy usage into account. For comparison, two strategies including digital network coding (DNC) and physica...

Though rapid increase in energy consumption has become a global problem, most of the solutions developed to address it for residential consumers are based on qualitative studies conducted with small numbers of users, typically in the developed world. Recent work has begun to explore consumption practices, and motivations, barriers and other factors affecting energy consumption in urban India. H...

Energy usage is becoming a challenge for the design of next generation large scale distributed systems. This paper explores an innovative approach of profiling such systems. It proposes a DNA-like solution without making any assumptions on the running applications and used hardware. This profiling based on internal counters usage and energy monitoring allows to isolate specific phases during th...

abstract— data grids are an important branch of gird computing which provide mechanisms for the management of large volumes of distributed data. energy efficiency has recently emerged as a hot topic in large distributed systems. the development of computing systems is traditionally focused on performance improvements driven by the demand of client's applications in scientific and business ...

Smart meters report power usage at 15 minute intervals and, compared to monthly power bills, provide the users with a much finer resolution time series of energy usage. However, apart from identifying times of peak energy usage, these smart meters provide little actionable data for the user in terms of reducing their power costs. Our research involves the development of an intelligent metering ...

A total factor energy saving target ratio (ESTR) for seventeen APEC economies over 1991-2000 is computed in this paper. All nominal terms are transformed into real terms at the 1995 price level. The data envelopment analysis (DEA) approach is used to find the energy-saving target (EST) for APEC economies without reducing their maximum potential GDPs. Energy, labor, and capital are the three inp...

Energy consumption share in construction part and dependent industries is about 40 percent of total energy consuming in Iran which is significant compared to other industries such as transportation, agriculture and therefore is of important. As energy consumption reduction and material durability improvement leads to cost reduction from one hand and environment pollution reduction on the othe...
