    Abstract: In order to preserve more image details and enhance its robustness to noise for image segmentation, an improved fuzzy c-means algorithm (FCM) for image segmentation is presented by incorporating the local spatial information and gray level information in this paper. The modified membership function and clustering center function are more mathematic... Show More

    Abstract: This paper presents a few aspects regarding the analysis of some dynamic regimes of asynchronous motors supplied at variable frequency. In this purpose, in the first part of the paper, there are detailed the Simulink blocks of a program for simulating the operation of driving systems with static converters with precomputed commutation moments. Then... Show More
