The complexity of transient electromagnetic scattering from objects in free space has been well known for years. Various scattering events, such as specular reflection, edge diffraction and creeping wave, increase the complexity. In this paper, a method in the view of the movement of free electrons to analyze the characteristics of transient pulses scattered from metal cylinder object both in near-field...
The stochastic nature of dielectric breakdown in MG/HK and poly-Si/SiON technologies is investigated. The voltage ramp stress (VRS) methodology was employed to demonstrate that the variability of the Weibull shape parameter, β·(n+1), diminishes with increasing sample size as predicted for a purely stochastic process. However, the V63 confidence limits remain essentially the same and do not follow...
In this paper, ATP-EMTP programme has been used to study on the lightning protection for the UHV substations during start-up operation mode, the researched result were given when the first tower which was nearest the substation was adopted shape A and shape B. The influence of the top hamper on outage rate due to shielding failure rate, and the a proper top hamper structure was proposed.
Through analyzing the concept and components of sports training process, the article concludes that the three-dimensional structure of the modern sports training process is systematically made up of time structure, content structure and control structure, each of them also has content system and internal relationship.
