The method of intelligent fault diagnosis based on wavelet packet transform and support vector machine is presented. The key to fault diagnosis is feature extracting and fault classifying. According to the method, the energy of frequency bands after wavelet packet decomposition of the vibration signals is taken as the extracted features and input to support vector machine(SVM). Then, fault pattern...
There are important significance and social benefit of the application for real-time classification by using of the combination of GA, PCA and Improved SVM in a road ramp. The eight test points were put on the both sides of the road ramp, extracted feature vectors. The acoustic and seismic signals were used to research the classification in real-time. Because the dimension of feature vectors is too...
By 2050, about a third of the French population will be over 65. To face this modification of the population, the current studies of our laboratory focus on the monitoring of elderly people at home. This aims at detect, as early as possible, a loss of autonomy by objectivizing criterions such as the international ADL or the French AGGIR scales implementing automatic classification of the different...
