Proactive Reliability Analysis for Electric Vehicles
Authors: Zhong Xiao Pin , Zeng Wen Wen
Published: August 2013

In this paper, a proactive strategy is proposed to analyze the system reliability in electric vehicles (EVs). The EVs system reliability is crucial and difficult to estimate because more electrical subsystems are employed such that the system is more complicated. Besides the component failure, we consider the uncertain dependency between components by using uncertain the logical structures of failure. The proposed method is theoretically based on the probabilistic graphical model. Therefore other tasks related to system reliability, such as fault diagnosis, can be converted to the inference problems of graphical model. Simulation examples demonstrate the effectiveness of our strategy.

Published: August 2013

The purpose of this study was to investigate the effects of human gait on air distribution in contagious isolation tent wards. The proposed contagious isolate tent wards were designed as the operating room for serious paroxysmal infectious patients. The three dimensions model of contagious isolation tent ward was reconstructed. Then, the computed fluid dynamical (CFD) methods were used to simulate and analyze the air distribution of contagious isolation tent ward. The dynamical meshes technology was employed to simulate the human gait. An experiment was implemented to measure air velocity of the proposed isolate tent ward. The results showed that the human gait motion affects air pressure, air velocity and contaminant distribution, while the impact on air temperature could be ignored. It was concluded that the impact of human gait or movements should be taken into account in air pollution control of contagious isolation tent wards.

Published: August 2013

By measuring the current-voltage (I-V) characteristics in the temperature range of 100 K to 300 K, mechanisms of the forward tunneling current and the reverse leakage current of GaN-based blue light emitting diodes are analyzed. For the forward current, both the temperature-independent current slope and an ideality factor larger than 2 are typical features of the defect-assisted tunneling mechanism. For the reverse leakage current, the linear relationship between I and (V+Vbi)1/2 indicates a hopping conduction mechanism at low bias, while the power law I-V relationship suggests that the space charge limited current dominates the reverse leakage current at high bias.

Influence of Al Composition on Donor Impurity States in Self-Formed GaAs-AlxGa1-xAs Quantum Rings
Authors: Wang Guang Xin , Duan Xiu Zhi
Published: August 2013

Based on the the effective mass approximation and variational approach, the donor impurity states confined in self-formed GaAs/AlxGa1-xAs quantum rings (QRs) are investigated theoretically. A uniform electric field is applied along the growth direction of the QR. The different effective masses in the different regions of the GaAs/AlxGa1-xAs QR are taken into consideration. Numerical results show that the binding energy of a donor impurity increases gradually, reaches a maximum value, and then decreases quickly to the special value as the QR height decreases. Given a fixed QR size, the binding energy increases for the impurity located at the center of the QR when the Al composition increases. In addition, it can also be found that when the applied electric field strength increases, the donor binding energy increases for impurities localized at the negative z axis of the QR; however, the donor binding energy decreases slightly for impurities located at the center and positive z axis of the QR.
