A maximum cruising range is adversely affected by electric power consumption of auxiliary electric components for heating and cooling. Under the assumption that range anxiety is one of the main barriers to the electrification of an Electric Vehicle (EV). Considering a heating ventilation air-conditioner (HVAC) system as a non propulsion electrical hotel load consumed more energy that respect to time...
The structure transformation of ZnO thin films properties influenced by substrate temperature deposited by RF Magnetron Sputtering is presented. This project has been focused on electrical, optical and structural properties of ZnO thin films. The effect of variation substrate temperature at 200°C∼500°C on the ZnO thin films have been investigated. The thin films were examined using two point probe...
Retrieval of land surface emissivity and temperature from microwave brightness temperature data is a complex problem. The diurnal variation of temperature due to the diurnal cycle of solar radiation and weather conditions makes this problem even more challenging. In this paper, we use solar radiation in modeling the temporal variation of the brightness temperature state of the surface. Solar insolation...
This paper describes a technique to determine electrical test temperature of devices made of conventional packages like QFP and BGA as well as new packaging technologies such as system-in-package (SIP) and wafer level packages. It is based on the signal propagation delays that are sensitive to temperatures within the chip. The technique was applied to a QFP device, fabricated in 0.35 micron technology,...
This paper reports the effect of firing temperature on the physical properties of the Al2O3-SiO2 based LTCC materials for RF applications. Al2O3-SiO2 material in the form of tape was prepared using mixed oxide method. The prepared tape was than laminated and fired at different firing temperatures in the range of 840 to 960degC. The physical properties of all samples were fully characterized, such...
