Permanent magnet (PM) machines have been widely used due to high torque density and high efficiency. However, PM machines have their inherent disadvantages, such as potential irreversible demagnetization due to winding terminal short-circuit failure. In this paper, the design concept of short-circuit fault-tolerance PM machine is proposed after exploring the instinct mechanism of magnetic field inside...
Mobile commerce (M-commerce) and radio frequency identification (RFID) are two major industries which everyone recognizes their contribution at the overall world economy. In order to have an integrated information system, the purpose of this paper is to integrate RFID technology with M-commerce so as to promote products and unique cross-selling to consumers, which can transform a traditional retail...
A comprehensive model is presented which enables the effects of ionizing radiation on bulk CMOS devices and integrated circuits to be simulated with closed form functions. The model adapts general equations for defect formation in uniform SiO2 films to facilitate analytical calculations of trapped charge and interface trap buildup in structurally irregular and radiation sensitive shallow trench isolation...
The results of this study showed that when excess hydrogen is introduced to gated bipolar devices in the radiation environment, the buildup of radiation-induced defects in device oxides and their annealing behaviors are dramatically changed due to hydrogen. The different annealing behaviors of oxide charge between hydrogen-rich and -depleted devices suggest that the defects contributing to the enhanced...
Several linear bipolar microcircuits commonly used in space have been selected to investigate whether hydrogen contamination has an impact on their total dose response. Results obtained from irradiations performed on the HSYE117 linear voltage regulator from Intersil and the AD590 temperature transducer from Analog Devices show a causal relationship between in-package hydrogen content and total dose...
One of the trends in performance appraisal is about modeling the work behaviors, and considerable researches show behavior process is an important factor contributing to the employee's total performance. Based on the contextual and task performance construct, we conduct a field research in Chinese engineering managers. The result shows the performance model consists of 3 dimensions: personal motivation,...
Mobile wireless telemedicine is the latest area that exploits novel advance in telecommunication technology which provides health care delivery to the inaccessible areas that are hampered by the limitation of the conventional telecommunication technologies. To provide intelligent and high quality monitoring services to patients, best-practice decision support to the professionals and cost-effective...
