Considering its large scale mixed integer nonlinear structure, a hybrid algorithm based on Genetic Algorithm and decomposition algorithm is developed to solve it. The model is divided into thermal power dispatch and hydro power dispatch subproblems respectively by using reservoir volumes as genetic variables which consider the complex relationship between reservoirs. These two subproblems are independently solved according to their own characteristics. The simulation results reveal that comparing with GA the hybrid algorithm is an effective method with shorter computation time and higher precision.","PeriodicalId":386083,"journal":{"name":"2011 International Conference on Mechatronic Science, Electric Engineering and Computer (MEC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125908391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The digital oscilloscope receiver is applied to obtain in real-time the full waveform characteristics of acoustic emission signal during the column damage process. Using signal processing and passive monitoring technology, this article conducts crack development of real-time dynamic monitoring and evaluation on the damage process of the two specimens by the piezoelectric sensors. The experiment results show that the generation and development of the cracks are obviously companying with the acoustic emission phenomena. The energy accumulation process of the acoustic emission signal has obvious deference from the two specimens and shows basically the property of the cracks development.

It is characterized of less computation, and easy to be realized in real-time. Inter-frame global motion vectors were predicted by feature corners matching based motion estimation. The global camera motion was defined in terms of constant velocity motion models, and adaptive α-β filtering was employed to facilitate smooth operation. Experimental results for many video sequences show that the method can eliminate high frequency dithering, remain the meaningful motion of camera and realize real-time image stabilization satisfactorily.
