The iterative property of inverse butterfly permutation network makes it possible to implement shift operation with simple routing algorithm, which has high application value in cryptography, digital image processing and other fields. Based on the inverse butterfly network, this paper proposes a subword shift unit, which integrates the operations of subword rotation shift, subword logical shift and...
Insulation monitoring is crucial to personal safety and equipment operation in the power distribution system. Recently, with the rapid development of distributed generators, the three-phase voltage-source PWM converter (VSC) is widely used as the bidirectional interface between the dc microgrids and the distribution networks. This paper presents the relationship between the response of insulation...
With the fast development of information and electronic technology, the digitized equipments are widely used in the troops. However, the power characteristic of the digitized equipment presents the pulsed state, named pulsed loads. There are typical characteristics of pulsed loads, e.g., the peak value of power is large but the mean value is small. Hence, the influence of pulsed load on power system...
The DC microgrid has the advantages of simpler control, higher power conversion efficiency and lower cost com pared with AC micro grid, which is the future development direction of smart grid. The method of autonomous control re quires no communication bus, it can improve reliability of the system and reduce the cost of the system. Therefore, this paper studies the key control problems of the autonomous...
Facing current on-orbit servicing tasks, a space arm-hand system is designed and developed in this paper. Firstly, through contrast and analysis, the arm configuration of non-biased elbow and spherical wrist is identified, and the space hand system adopts the five-fingered dexterous robot hand. Secondly, the 6-DOF space arm system is accomplished including humanoid links and two different types of...
Iron oxide sorbent is used as high temperature desulfurization sorbent due to high sulfur capacity, easy regeneration and recovery elemental sulfur. In this paper, the iron oxide based high-temperature sorbent was obtained by mixing iron oxide with calcium oxide, extrudating and calcinating. The sulfidation, reduction and regeneration performance for the prepared iron oxide based desulfurization sorbent...
