This paper presents a parameter study for optimum rotor geometrical parameter combinations of a refrigeration helical twin screw compressor with four commonly used lobe combinations and five different length/diameter ratios and wrap angles. The volumetric and indicated efficiencies of the compressor are important. So also are other factors such as rotor deflection, bearing load, bearing life an...

The aim of this paper is computing of the optimum duty cycle and inductance using Genetic Algorithm to minimize tracking error and operating costs by means of a new current reference. Such a current reference is able to share the responsibilities in power quality deterioration between supply and customer, making the filter to deliver a current with a lower harmonic content, which means a lower ...

This paper introduces a new way for obtaining the optimum solution of prior parameters in survival analysis. Firstly, we give the definition of deviation limit, and discuss a property of prior parameters. Secondly, we present a method for obtaining the optimum solution of prior parameters with exponential distribution. Finally, we deal with a real data set, through which we can see that the pre...

The finding a maximum or a minimum function problem under some constraint conditions are called optimization problem. Almost every engineering design problem can be formulated as optimum problems. Solving the optimum problem requires the computation of the global maxima or minima of the objection function. Many heuristic intelligent algorithms had been developed and adapted to several optimal d...

Ant Colony System (ACS) is a distributed (agentbased) algorithm which has been widely studied on the Symmetric Travelling Salesman Problem (TSP). The optimum parameters for this algorithm have to be found by trial and error. We use a Particle Swarm Optimization algorithm (PSO) to optimize the ACS parameters working in a designed subset of TSP instances. First goal is to perform the hybrid PSO-A...
