Multiplierless discrete Fourier transform based on moments by LIU Zhen-bing, LIU Jian-guo, WANG Guo-you

“…A novel algorithm to perform Discrete Fourier Transform（DFT） multiplierlessly was proposed.First, by modular mapping and truncating Taylor series expansion, the DFT was expressed in the form of the product of the constants and discrete moments.Second, by performing appropriate bit operations and shift operations in binary system, the product could be transformed to some additions of integers.The proposed algorithm only involved integer additions and shifts because the discrete moments could be computed only by integer additions.The systolic VLSI was designed to perform the new algorithm, followed by complexity analysis.Compared with the state-of-the-art systolic structure, the proposed design was multiplierless and easier to implement with less hardware and time.The approach was also applicable to other discrete transforms.…”

Fault diagnosis based on sliding mode observer for formation of UAVs by Jun-peng SHI, Jian-wei LIU, Pu YANG, Bin JIANG

“…Under the directed network topology,formation of UAVs with leader-follower structure was studied.And a fault estimation method using distributed adaptive sliding mode observer was designed for actuator fault with unknown upper bound.First of all,for each network node,based on the directed network topology,relative output estimation error was introduced to show information exchanges between neighbouring nodes.And a corresponding sliding mode observer was constructed.Then the global error system was defined,and the stability and sliding mode reaching condition was proved by Lyapunov theory.At last,all the parameters to be designed were calculated by the linear matrix inequality toolbox,and the validity of the proposed method was verified by Matlab simulation.…”

Experimental Study on Shape and Discharge Capacity of Spillway of Yuyang Lake by LI Songping, JIA Wenbo, ZHAO Yuliang, ZHAO Xueping, CAI Yi

“…According to the actual operation of spillway of Yuyang Lake in Jiyuan City,this paper systematically studies the spillway shape,discharge capacity,flow pattern &velocity,pressure distribution,energy dissipation and scour prevention based on the hydraulic model test,and further optimizes the engineering design through the comparison test of different schemes.The test results show that the discharge capacity can meet the design requirements after the spillway inlet elevation is reduced;and the energy dissipation is improved after the stilling basin is changed from the secondary level to the first level,which can play a good role in protecting the downstream.In view of the phenomenon that the water flows through the top of the wall,reasonable suggestions are put forward to heighten the pier head at the inlet and the wing wall at the downstream of the spillway.…”

Cache replacement strategy based on content value by Dan HUANG, Rongfang SONG

“…The cache replacement mechanism is one of the important research issues of the content center network.Considering the limited cache space,the reasonable replacement of the cache content becomes a key factor affecting the overall performance of the network.Therefore,a cache replacement scheme based on content value was designed.Considering the dynamic popularity of content,the cost of caching,and the time of the most recently requested,a more realistic content value function was built,and an effective content storage and replacement scheme was designed based on the content value function.Specifically,when the cache space was insufficient,the existing cache contents were replaced according to the value from small to large.Simulation results show that compared with the traditional replacement algorithms LRU,LFU and FIFO,the proposed scheme effectively improves the content cache hit rate of network nodes and reduces the average hops of users’ content acquisition.…”
