摘要：This paper analyzes the fuzzy variable structure control algorithms for delay systems and describes the compensation mechanism of the integral factor to the effect of the delay. Based on the linearized model of the congestion-avoidance flow-control mode of transmission control protocol (TCP), we present delay control algorithms for active queue management (AQM) and discuss the parameter tuning of the algorithms. The NS (network simulator) simulation results show that the proposed control scheme for the nonlinear TCP/AQM model has good performance and robustness with respect to the uncertainties of the round-trip time (RTT) and the number of active TCP sessions. Compared to other similar schemes, our algorithms perform better in terms of packet loss ratio, throughput and butter fluctuation.

摘要：Objective To evaluate the efficacy of Tuina(Chinese therapeutic massage)manipulation plus horse-riding squat exercise in treating knee osteoarthritis(KOA)and optimize the combining *** Based on a 2×2 factorial design,120 eligible KOA patients were randomized into a manipulation group(group A1B2),a manipulation plus horse-riding squat group(group A1B1),a sitting knee-adjustment group(group A2B2 group),and a sitting knee-adjustment plus horse-riding squat group(group A2B1),with 30 cases in each *** intervention was conducted three times a week,lasting for four *** Western Ontario and McMaster Universities osteoarthritis index(WOMAC)was taken as the major measure for efficacy evaluation(including three component scores,pain,stiffness,and daily function,and total score).Results The three component scores(pain,stiffness,and daily function)and the total score of WOMAC showed significant differences after the intervention in the four groups(P0.05).The extensor peak torque at 180°/s changed significantly in group A1B2 after treatment(P0.05).The main effect of manipulation showed significant in affecting the WOMAC pain and total scores(P<0.05).The main effect of horse-riding squat exercise showed significant in affecting the WOMAC pain and stiffness sco
