In this paper, optimal placement of Phasor Measurement Unit (PMU) using Global Positioning System (GPS) is discussed. Ant Colony Optimization (ACO), Simulated Annealing (SA), Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) are used for this problem. Pheromone evaporation coefficient and the probability of moving from state x to state y by ant are introduced into the ACO. The modifi...

Using Machine Learning and Integer Optimization to Help Improve Employment Outcomes of Resettled Refugees

this paper presents a fault location technique for transmission lines with minimum current measurement. this algorithm investigates proper current ratios for fault location problem based on thevenin theory in faulty power networks and calculation of short circuit currents in each branch. these current ratios are extracted regarding lowest sensitivity on thevenin impedance variations of the netw...

In this paper, a nominal sensor placement methodology for leak location in Water Distribution Networks is presented. To reduce the size and the complexity of the optimization problem a clustering technique is combined with the nominal sensor placement methodology. Some of the pressure sensor placement methods for leak detection and location in water distribution networks are based on the pressu...

Design hierarchy plays an important role in timing-driven placement for large circuits. In this paper, we present a new methodology for delay budgeting based timing-driven placement. A novel slack assignment approach is described as well as its application on delay budgeting with design hierarchy information. The proposed timing-driven placement flow is evaluated using an industrial place and r...
