Flexibility plays an important role in fish behaviors by enabling high maneuverability for predator avoidance and swimming in turbulence. In this paper, we present a novel, flexible fish robot equipped with distributed pressure sensors for flow sensing. The body of the robot is made of a soft, hyperelastic material that provides flexibility. The fish robot features a Joukowskifoil shape conduci...

This paper proposes a Flexible Power Electronic Transformer (FPET) for the application in the micro-grids. The low frequency transformer is usually used at the Point of Common Coupling (PCC) to connect the low voltage grid and utility network to each other. The conventional 50Hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. In this pap...

Flexible Alternating Current Transmission System (FACTS) devices can regulate the active and reactive power control as well as adaptive to voltage magnitude control simultaneously, because of their flexibility and fast control characteristics. Placement of these devices in suitable location can lead to control in line flow and maintain bus voltages in desired level and so improve voltage stabil...

Instead of using conventional flaps to generate torques, we explore the feasibility of applying micromachined sensors and actuators to control leading-edge vortices, and consequently, provide sufficient moments for flight control. By utilizing a “flexible skin” containing 64 micromachined shear stress sensors, instantaneous separation line on the leading edges can be detected. We applied microa...

This paper is concerned about the sequencing problems in pull production systems which are composed of one mixed-model assembly line and one flexible fabrication flow line with limited intermediate buffers. Two objectives are considered simultaneously: minimizing the total variation in parts consumption in the assembly line and minimizing the makespan in the fabrication line. The mathematical m...

Genetic algorithms (GAs) have been used widely for such combinatorial optimization problems as the traveling salesman problem (TSP), the quadratic assignment problem (QAP), and job shop scheduling. In all of these problems there is usually a well defined representation which GA's use to solve the problem. We present a novel approach for solving two related problems-lot sizing and sequencing-con...

This paper introduces some advanced genetic algorithms for a complex hybrid flexible flow line problem with a makespan objective that was recently formulated. General precedence constraints among jobs are taken into account, as are machine release dates, time lags and sequence dependent set-up times; both anticipatory and non-anticipatory. This combination of constraints captures many real worl...

The increasing growth in power demand and the penetration of renewable distributed generations in competitive electricity market demands large and flexible capacity from the transmission grid to reduce transmission bottlenecks. The bottlenecks cause transmission congestion, reliability problems, restrict competition, and limit the maximum dispatch of low cost generations in the network. The ele...

Improving ATC is important in the current deregulated environment of power systems. In this paper, ATC is computed using Continuous Power Flow (CPF) method considering line thermal limit and bus voltage limits. Flexible Alternating Current Transmission system (FACTS) can control magnitude of voltage, phase angle and circuit reactance and the load flow may be re-distributed to regulate bus volta...
