Lightweight, flexible and high-performance (high efficiency low reflection) electromagnetic interference (EMI) shielding materials are urgently needed to cope with the increasingly complex (EM) radiation environment. In this study, thermoplastic polyurethane/expanded graphite/silver (TPU/EG/Ag) composite foams three-dimensional (3D) isolated conductive network were successfully manufactured through combination of supercritical carbon dioxide (scCO2) foaming chemical deposition. This foam...
Abstract A minority carrier lifetime of 25.46 μs in a P-type 4H-SiC epilayer has been attained through sequential thermal oxidation and hydrogen annealing. Thermal can enhance the by reducing carbon vacancies. However, this process also generates clusters with limited diffusivity contributes to enlargement surface pits on 4H-SiC. High-temperature annealing effectively reduces stacking fault dislocation density. Moreover, electron spin resonance analysis indicates significant reduction...
The methodology for studying a tyre blow-out process using both experiments and simulations is presented in this paper. To achieve this, generator an experimental device are developed. Moreover, the static state implemented. Then, finite element model corresponding to established. results show that developed can effectively replicate sudden inflation pressure loss without inflicting permanent damage on structure. comparison between shows simulate phenomenon simulation analysis method correct...
A large number of cohesion measures based on method-attribute references have been proposed. However, virtually no attention has paid to the abstract representation that objectively depicts relationships among members a class. Specially, flow dependence relationship attributes, indirect and potential class members, direction are ignored. To address this problem, we first identifies four types basic uses member graph represent all dependences Then, measure for measuring cohesiveness is...
The Jinwan Offshore Wind Farm project in the Pearl River Estuary (PRE) is a new stressor for resident marine mammals there, especially Indo-Pacific finless porpoise. A broadband recording system was deployed Farm, before and during construction period, order to determine how porpoise responded pile driving activity. results showed that wind farm area an important habitat monitoring period. also avoidance behavior of There significant negative correlation between detection detection, time...
A minority carrier lifetime of 25.46 $\mu$s in a P-type 4H-SiC epilayer has been attained through sequential thermal oxidation and hydrogen annealing. Thermal can enhance the by reducing carbon vacancies. However, this process also generates clusters with limited diffusivity contributes to enlargement surface pits on 4H-SiC. High-temperature annealing effectively reduces stacking fault dislocation density. Moreover, electron spin resonance analysis indicates significant reduction vacancy...
Abstract A light-emitting-diodes (LEDs)-integrated silicon carbide (SiC) insulated gate bipolar transistors (LI-IGBT) is proposed in this paper. The novelty of the LI-IGBT depends on photogeneration effect III-nitride LEDs embedded poly-Si regions IGBT. Then, photogenerated carriers are formed JFET region and drift layer, indicating increase conductivity as compared with SiC IGBT hole-barrier layer (H-IGBT) charge storage (CSL-IGBT). static simulation results show that electron density at...

With the rapid development of Internet, integrated applications Web, database, CORBA and Java have offered three-tiered client/server application models a good computing environment implementation strategy. This paper briefly introduces this kind model based on discusses persistent object service for it. The describes in detail service's architecture model, interactive process components, main interface descriptions some considerations when implementing Finally, summary is supplied service.
A novel silicon carbide (SiC) insulated gate bipolar transistor with short super junction (SSJ-IGBT) is proposed in this article. The specific ON-resistance (RON,sp) of SSJ-IGBT decreased by 10.87% compared conventional IGBT (C-IGBT). Due to the fact that high doping N-pillar causes low resistance and improves conductivity modulation. P-well fully protected junction. Thus, a reduced corner field below 2 MV/cm can be achieved OFF-state. Furthermore, due SSJ structure, carriers drifted buffer...
When the wind speed is above rated value, output power of turbine should be maintained at value in order to prevent generation system from overheating.In addition, natural will fluctuate randomly a large range values, making traditional control effect not ideal.This paper presents novel H-infinity (H ∞ ) pitch strategy for Wind Turbine Generators (WTGs), which can make rotor and constant when changes range.In shorten response time reduce overshoot, specific solution, method combines H theory...
