No single retargeting approach performs well on all images and all target sizes; therefore, hybrid algorithms are often considered as promising alternatives. However, most hybrid schemes are time consuming. In this paper, we propose a fast hybrid framework in which the Fast Content-Aware Image Distance (FCAID) is used to connect fast seam carving with neighboring probability constraints (FSc_Neip)...
The study is focused on the partial discharge detection of the gas insulated switch using ultra-high frequency (UHF) method. The radiated electromagnetic wave generated due to internal defect was measured by the self-made ultra-high frequency micro-strip antenna, based on which so as to determine whether if partial discharge will occur. In this article, we make effort in analyzing the exciting, transmission,...
Traditional formal method has been solved the problems of functional modeling and verification of Web service composition, but it could not effectively analyze and calculate the costs of the service composition. A minimum cost composition algorithm based on process algebra CSP is proposed. The algorithm first translates the XML format Web service composition description to CSP format formal description...
The control strategies of Switched Reluctance Motor (SRM) can be divided into current chopper control (CCC) angle position control (APC) and pulse width modulation (PWM). Because these methods have their advantages and disadvantages, a single control strategy is difficult to meet the needs. The paper applies current chopper control in low-speed, and adopts angle position control in high-speed. Using...
According to the theory of Voltage Source Converter (VSC) can control active power and reactive power simultaneously and independently, back-to-back VSC is applied to the synchronous parallel operation in power grids. Combined with the characteristic of UPFC circuit structure, this paper proposes a new scheme based on power transmission which can realize integrated functions of power system synchronization...
In this paper, the control strategy of transformer coupling three phase bridge type solid state fault current limiter (TC-SSFCL) is presented. It is validated in an experimental system. It's proved that the control strategy ensures TC-SSFCL has excellent control performance and current-limiting effectiveness in its normal startup, operation and current-limiting conditions. Issues faced by TC-SSFCL...
A compact Ka-band transceiver module with two channels has been developed. This transceiver module consists of two DRO resources, E-plane waveguide filter, coupler, power dividers, over 200 components and 15 MMICs which conclude one mixers, one frequency multiplier, one low noise amplifier, five amplifiers and seven switches, and has superior performance of switch rise-time and fall-time less than...
