Abstract Solar air heaters are seen as a promising option for reducing the building energy demand in particular when combined with heat pumps。 In this work, a modeling tool to predict the performances of heat pump driven by solar heater i...
The thermal modeling of a composite fuel consisting of continuous second phase in a ceramic (uranium oxide) matrix has been carried out with aid of detailed examination of the microstructure of the composite and the interface structure。 B...
Abstract Cobalt60 and 10 MeV proton irradiations have been carried out on n-buried channel frame transfer CCDs in order to study changes in charge transfer efficiency (CTE) and dark current for room tem rature, 1ps/pixel, readout conditions。...

摘要：移动自组织网络是一组形成没有任何固定的基础设施或中央管理的帮助下临时网络的无线移动设备。这些装置的特征在于以下特点;移动性，异质性，有限的电池功率。在这样的环...
Abstract-This paper presents a fully synthesizable digital controller for high-frequency low-power DC-DC switching mode power supply (SMPS)。 Key module of the digital controller is a Hybrid digital pulse-width modulator (DPWM), which take...
PLC Introduce Plc Introduction Programmable controller is the first in the late 1960s in the United States, then called Plc programmable logic controller (Programmable Logic Controller) is used to replace relays。 For the implementation of...
Abstract People in rural areas at present are still beyond the coverage of pure and fresh water for their daily usage。 However, these constraints offer an opportunity for green technology to embrace the peoples needs and shortages。 Vast...
ABSTRACT The objective of this study is the development of a computationally efficient CFD-based tool for finding optimal engine operating conditions with respect to fuel consumption and emissions。 The optimization algorithm employed is...
ABSTRACT Large Eddy Simulation (LES) with a flamelet time scale combustion model is used to simulate diesel combustion。 The flamelet time scale model uses a steady-state flamelet library for n-heptane indexed by mean mixture fraction, mix...
