Energy consumption is a matter of common concern in the world today. Research demonstrates that as a consequence of the constantly evolving and expanding field of information technology, data centers are now major consumers of electrical energy. Such high electrical energy consumption emphasizes the issues of sustainability and cost. Against this background, the present paper proposes a power l...

This paper discusses non-intrusive electrical energy monitoring (NIEM) system in an effort to minimize electrical energy wastages. To realize the system, an energy meter is used to measure the electrical consumption by electrical appliances. The obtained data were analyzed using a method called multilayer perceptron (MLP) technique of artificial neural network (ANN). The event detection was imp...

Energy gives personal comfort to people, and is essential for the generation of commercial and societal wealth. Nevertheless, energy production and consumption place considerable pressures on the environment, such as the emission of greenhouse gases and air pollutants. They contribute to climate change, damage natural ecosystems and the man-made environment, and cause adverse effects to human h...

– Energy management embodies engineering, design, applications, operation, and maintenance of electrical power systems to provide optimal use of the electrical energy. The key element of the energy management process is the identification and analysis of energy conservation opportunities. This paper utilized the characteristic of a digital signal processor TMS320LF2407, a novel Wheel Robert ene...

Duplex and Triple Modular Redundancy (TMR) systems are used when a high-level of reliability is desired. Real-Time Systems for autonomous critical missions need such degrees of reliability, but energy consumption becomes a dominant concern when these systems are built out of high-performance processors that consume a large budget of electrical power for operation and cooling. Examples where ene...

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...

Since the power consumption of different electrical appliances in a household can be recorded by individual smart meters, it becomes possible to start considering in more details the interactions of the residents with those devices throughout the day. Appliances usages should not be considered as independent events, but rather as enablers for activities. In this work, we propose an automated me...

The energy consumptions in households and the energy resources used for fulfilling the energy needs have been changing in a quite short period of time. The present study aims to provide a background of the energy consumptions in Portugal in a European context. A significant part of the energy consumptions is related to buildings. It is estimated that buildings use about 40% of all the energy ne...

PROPOSAL Microsystems such as laptop computers, tablets, smart-phones, power electronics equipment, radio-frequency devices, and solid-state lighting are becoming an increasing part of our daily lives. The collective energy consumption by these devices, as well as the associated back-end equipment and facilities continues to grow rapidly and is a major concern for their sustained growth. Reduci...
