Processing of magnesium （Mg） matrix composites reinforced with low reinforcement content （up to 4-5 vol.%） of graphene nanoplates （GNPs） and silicon carbide （SIC） nanoparticles using bait milling and spark plasma sintering （SPS） is reported. Near full densification was observed for all the composite compositions at the sintering temperature of 450 ~C （soaking time of 5 min and applied pressure of 50 MPa）. Detailed analysis of the microstructure and mechanical and tribological （under dry sliding contact with alumina counter-face） properties with reinforcement content in Mg-GNP and Mg-SiC is presented. Mg-GNP and Mg-SiC composites reinforced with about 2 vol.% of reinforcement content exhibited significant improvement in microhardness and wear resistance as compared with Mg compacts.

传统的模块化多电平换流器(modular multilevel converter,MMC)的控制系统包括功率、电压控制等上层控制和控制环流的下层控制。直流系统可配合功率振荡抑制(power oscillation damping,POD)控制器为交流系统提供阻尼,但直流功率会根据POD控制器的输出而振荡。MMC桥臂电容器的能量可以用来平衡交流系统功率变化,从而保证直流功率的稳定。MMC的能量控制,可以控制环流电流的直流分量,从而灵活控制MMC桥臂电容器的能量。基于能量控制,该文设计一种能量补偿控制,数学分析MMC电容器上可利用的能量,并在PSCAD/EMTDC仿真平台上模拟MMC-HVDC为2机交流系统提供阻尼,可以验证能量补偿控制可以暂态解耦直流系统两端功率传输,从而将能量补偿控制用来解决嵌入式直流的3机系统使用传统POD控制方式时会导致振荡加剧的问题,证明采用能量补偿控制的必要性。

Novel high speed energy efficient square root architecture has been reported in this paper. In this architecture, we have blended ancient Indian Vedic mathematics and Bakhshali mathematics to achieve a significant amount of accuracy in performing the square root operation. Basically, Vedic Duplex method and iterative division method reported in Bakhshali Manuscript have been utilized for that computation. The proposed technique has been compared with the well known Newton-Raphson’s (N-R) technique for square root computation. The algorithm has been implemented and tested using Modelsim simulator, and performance parameters such as the number of lookup tables, propagation delay and power consumption have been estimated using Xilinx ISE simulator. The functionality of the circuitry has been checked using Xilinx Virtex-5 FPGA board.

In this paper,focus has been given to design and implement signed binary subtraction in quantum *** the type of operand may be positive or negative,therefore a novel algorithm has been developed to detect the type of operand and as per the selection of the type of operands,separate design techniques have been developed to make the circuit compact and work very *** separate methods have been shown in the paper to perform the signed *** results show promising for the second method in respect of ancillary input count and garbage output count but at the cost of quantum cost.
