Abstract:

Extraordinary improvements in computing performance, density, and capacity have driven rapid increases in system energy consumption, motivating the need for energy-efficient performance. Harnessing the collective computational capacity of thousands of these systems can consume megawatts of electrical power, even though many systems may be underutilized for extended periods of time. At scale, powering and cooling unused or lightly loaded systems can waste millions of dollars annually. To combat this inefficiency, we propose system software, control systems, and architectural techniques t

Generators are widely used across the world as portable power units in case of power outages, used for emergency services and are also used in rural areas without access to electricity.

With operating conditions vastly different than that of automobile engines, they can be re-designed to operate much more efficiently as generator engines.

Waste sludge is frequently treated by anaerobic digestion to kill pathogens, generate methane gas and reduce odors so the sludge can be safely land applied. In an attempt to reduce sludge volumes and improve sludge dewatering properties, the use of thermal hydrolysis (TH), a sludge pretreatment method, has been adopted by numerous wastewater treatment plants, among them being the District of Columbia Water and Sewage Authority (DC WASA). The use of anaerobic digestion in collaboration with thermal hydrolysis has been shown to increase VS removal, COD removal and biogas production. The sludge

Abstract:

The need for heating and cooling in buildings constitutes a considerable part of the total energy use in a country and reducing this need is of outmost importance in order to reach national and international goals for reducing energy use and emissions. One important way of reaching these goals is to increase the proportion of renewable energy used for heating and cooling of buildings. Perhaps the largest obstacle with this is the often occurring mismatch between the availability of renewable energy and the need for heating or cooling, hindering this energy to be used directly.

Abstract:

碩士<br>大葉大學<br>機械工程研究所<br>88<br>In an engine cycle, combustion thermal efficiency is the most important factor to affect engine performance. How to convert the heat released from combustion into engine brake work efficiently is the main concern of an engine designer. This research looks into the conversion efficiency of an engine deeply by zero-dimensional model together with heat release analysis method. By changing the relevant parameters of engine combustion, such as efficiency parameter a, form factor m, crank angle of start of combustion, combustion duration angle and speed of e

碩士<br>中原大學<br>企業管理研究所<br>98<br>For the past decades, enterprises faced against an environment of air pollution, energy shortage and global warming. Consequently, government urged the enterprises to use renewable energy and energy savings on one hand and persuade the relevant industries to adopt green accounting on the other hand. The purpose of this study is to investigate the impact of the environment cost on the energy related industries and set a policy for efficiency evaluation. Specifically, this investigation the management of the thermal power plant, analyzes the influence of environmen

碩士<br>大葉大學<br>電機工程學系<br>102<br>This paper presents a new photovoltaic/thermal air collector. Using fin-type heat sink to be the substrate of photovoltaic module that increasing the cooling area and improving the cooling performance. Adding blower to increase the air flow and recover the waste heat in the same time. Using MATLAB/Simulink to design the model of new photovoltaic/thermal air collector. The ambient parameters are used to simulate the temperature, the photovoltaic efficiency and the thermal efficiency. Simulate results was found the average photovoltaic efficiency is 12.46%, the ave
