Location based services are the hottest applications on mobile device nowadays. Indoor wireless position is the key technology to enable location based service to work well indoors, where Global Position System normally couldn't work. The main tendency of indoor wireless position is based on Bluetooth and RSSI (radio signal strength indicator). RSSI is the key parameter for wireless position. But...
A new and practical solution, Quantum-behaved Particle Swam Optimization (QPSO) algorithm, is applied to Aeroengine maximum thrust optimization implemented for some turbo fan engine. Simulation is carried out under different altitudes and velocities and shows that thrust can be increased by 7%~9%, 3%~5% more than by Particle Swam Optimization (PSO) algorithm. The influence of initial values on PSO...
