Optimal selection of marine propellers based on Wageningen B-Series
This research focus on analysing the feasibility of applying the optimization method to the propeller selection. The basic design process is modelled as a constrained optimal problem. The objective function ( propeller performance ) is optimized subjected to constraints imposed by cavitation, required propeller thrust and available engine power

New approaches in tool path optimization of CNC punching machine by simulated annealing
Many researches have shown that tool-path time accounted for an average of 70% of the total production time in sheet metal punching. In this paper, the authours present simple but efficient approach to determine the optimun sequence in CNC punching manufacturing. The simulated annealing and dynamic programming are used to solve this problem.

Optimal Location of TCSC for Social Welfare Maximization in Deregulated Electricity Market
In a competitive electricity market, congestion leads to decreasing Social Welfare. Hence, congestion management, Social Welfare Maximization is one of the technical challenges for Independent System Operator (ISO). The congestion can be eliminated /alleviated by improving transfer capability of the network.

Automated architectural reconstruction using refsrence planes under convex optimization
In this paper, a method for the automated reconstruction of architectures from two views of a monocular camera is proposed. While this research topic has been studied over the last few decades, we contend that a satisfactory approach has not yet been devised. Here, a new method to solve the same problem with several points of novelty is proposed. First, reference planes are automatically detected using color, straight lines, and edge/vanishing...

This paper presents a new Fuzzy Logic approach for optimization field oriented control for induction motor to reduce power losses. Among the many loss minimization algorithms (LMA) for an induction motor, a loss modelbased approach has the advantages of fast response and high accuracy. However, the performance of the loss model controller (LMC) depends on the accuracy of the modeling of the motor drive and losses. The paper describes a fuzzy...
