the pig growth environment is one key factor which affects breeding economic efficiency, this paper has developed distributed automatic control system of pig house environment based on fieldbus, the system includes the networks of CAN bus and Intranet and GPRS, remote users access the system server through browser to monitor the on-site controlling units,(More)
To analyze the in vivo effect of Escherichia coli Nissle 1917 (EcN) with different courses and different doses to Sprague–Dawley rats with trinitrobenzene sulfonic acid (TNBS)-induced colitis. The probiotic was orally administered with different courses of treatment (with or without pre-administration) and different doses (107–109 CFU/day) to Sprague–Dawley(More)
In this paper, an AC 2-degree freedom hybrid magnetic bearing (HMB) is proposed, which is driven by a 3-phase AC power inverter. The configuration and the operating principle producing magnetic suspension forces of the AC 2-degree freedom HMB are introduced. By using equivalent magnetic circuit method, the calculation formulas of magnetic suspension forces(More)
In order to solve the L2-L∞ control problem for a class of Markov jump systems subject to actuator saturation, a design method of the mode-dependent dynamic output feedback controllers is proposed.Based on stochastic stability for the closed-loop system, L2-L∞ dynamic output feedback controller is designed. The concept of domain of(More)
Markowitz proposed the theory of asset portfolio via a mean-variance model for security investment combination in 1952. The issue of security investment is still challenging till now. Intelligence algorithms were flourishing in resent years. Particle Swarm Optimization (PSO) is inspired by social behavior of bird flocking or fish schooling. It is(More)
