The influence of different short circuit (SC) test conditions, including bias voltages and case temperature, on the degradation of Silicon Carbide (SiC) MOSFETs performance is investigated. Sentaurus TCAD is utilized with the trap degradation model included in the simulations to assess the density of hot holes trapped in the gate oxide during this procedure. Simulation results demonstrate that higher...
Degradation test is an important technique to assess the failure time distribution of complex systems and high reliable products. The effectiveness of a degradation model depends strongly on the appropriateness of the model describing the degradation process. In this paper, a new degradation model is proposed, in which the characteristics of the widely-used stochastic process model and degradation...
The function of implantable glucose sensor is hindered by post-implantation effects such as biofouling and negative tissue responses both of which lead to permeability reducing fibrous encapsulation. Utilization of drug-eluting composite coatings based on dexamethasone-containing poly (lactic-co-glycolic) acid (PLGA) microspheres and poly (vinyl alcohol) (PVA) hydrogel matrix has been shown to suppress...
Image degradation is associated with many factors. We first give a brief introduction for the optical theory of defocused image, and then discuss the models of defocusing and introduce an effective way to calculate the PSF (Point Spread Function) of defocus. With the Gaussian model and degradation of defocus in parameter estimation, we propose a new method to reconstruct defocused image, which is...
