Random torque disturbances generated by magnetic bearings eccentric magnetic force have negative effects on the output torque precision of the magnetic suspended reaction flywheel(MSRFW). In order to eliminate the negative effects, dynamic models of flywheel system including motor and the buck DC-DC converter are established and a synergetic control approach for speed mode operation is presente...

Recent data showing that glucan stimulates defense reactions in plants through synthesis of resveratrol, led us to study the possible synergetic effects of a glucan-resveratrol complex on immune reactions in mice. We measured phagocytic activity, expression of CD4 marker on spleen cells, IL-2 secretion and antibody response. In all cases we confirmed the stimulatory effects of glucan. Resveratr...

Aim: The combination of different antimicrobial agents and subsequent synergetic effects may be beneficial in treatment of P. aeruginosa infections. The aim of the present study was to determine antibiotic susceptibility patterns of clinical isolates of P. aeruginosa and the effect of different antibiotic combinations against the multidrug-resistant (MDR), biofilm-producing bacterium P. aerugin...

Cache prediction for preemptive scheduling is an open issue despite its practical importance. First analysis approaches use simplified models for cache behaviour or they assume simplified preemption and execution scenarios that seriously impact analysis precision. We present an analysis approach for m-way associative caches which considers multiple executions of processes and preemption scenari...

In this paper, an almost new control approach called terminal synergetic control which works based on user defined manifold is applied to a nonlinear helicopter model. Stability analysis is convestigated using Lyapunov stability theory. Synergetic controller is applied to this nonlinear fifth-order helicopter model to control height and angle. Simulation results showed that it has faster and sm...

This paper presents a novel optical-electronic shape recognition system based on synergetic associative memory. Our shape recognition system is composed of two parts: the first one is feature extraction system (FES); the second is synergetic pattern recognition system (SPRS). Hough transform is proposed for feature extraction of unrecognized object, with the effects of reducing dimensions and f...

Biodiesel, produced by the transesterification of vegetable oils or animal fats with methanol, is a promising alternative diesel fuel. In this study, a series of strong base anion resins with different basicity, pore structure, degree of cross-linking, and particle size were investigated as heterogeneous catalysts for the transesterification of soybean oil with methanol. A trace amount of CH3ON...
