The objective of this paper is to compare the permanent magnet synchronous generator (PMSG) systems for wind turbines with the different drive trains and power ratings by design optimization. The comparison is mainly based on the cost and annual energy production (AEP) for a given wind climate. Firstly, the analytical models of the wind turbine, the 1-stage and 3-stage gearbox, the 3-phase radial-flux...
The exterior and interior displacements of the earth-rock dam are the important characters which can reflect its operation state. And it also has pivotal function in evaluating the quality of the project and judging whether the crack of the dam appears. The initial omission settlement is a popular problem in the observation of the earth-rock distortion. Because of the constructing schedule, the settlement...
As well known, because of the complicated watery environment and the limitation of the detecting method, recognizing the underwater target precisely is always a Gordian knot to all countries. In this paper, we designed a genetic-based classifier system (CS) which recognizes a target utilizes audio fingerprints. Audio fingerprint technology extracts some unique feature from a given sound clip, and...
