the measured dynamometer card used to analyze working conditions of pumping units requires a large amount of manpower and material resources, and thus it is very necessary to develop a novel and simple method for the diagnosis of pumping conditions. In this paper, a patternrecognition algorithm is proposed for the classification of working conditions of oil wells based on electrical parameters. To this end, the data of electrical parameters are obtained by the acquisition system;according to the algorithm theories (logistic regression, support vector machine, principal components analysis) of patternrecognition in machine learning, the binary and multiple classifiers of condition diagnosis are used to realize the diagnosis of the working conditions of the oil wells based on electrical parameters. the improvement of the proposed algorithm has been verified by analytical and simulation results.

In this paper, a neural network system used for patternrecognition of partial discharge (PD) is described. the neural network is a three-layer artificial neural system with read forward connections, and its learning method is back propagation algorithm incorporating with an external teacher signal, Digital PD pulse signal can be obtained by a PD pulse digitized record system. Combination of the discharge magnitude, the phase angle of applied voltage at which PD occurs, and the numbers of pulse counts are taken as the input of the neural network system, After learning typical input patterns, the neural network may discriminate unknown patterns successfully. Some new results are given, and practical application of neural network for patternrecognition of PD in large turbine generators is also discussed.

In recent years ″software engineering″ has emerged as a discipline of programming. It includes the conceptualization, design, implementation, testing and modification of software systems. Related issues are languages, standards, distributed and parallel processing, and total programming environments. the fact that more than 80 percent of system development costs were in software rather than hardware helps one appreciate the importance of any effort to understand and enhance the software production process. Many patternrecognition projects involve fairly large software efforts. It makes sense not only for researchers to make use of the latest software tools and methodologies but also to anticipate future changes.
this study focuses on recognizing the travel modes and activity types in personal travel trajectory. Firstly the paper proposes a concept of trip-Activity chain pattern to describe the general form of travel trajector...

Humans interact socially withthe help of facial expressions. Even health states or pains are reflected through facial expressions and hence can be useful in healthcare. Here, a facial expression recognition system is proposed. the bandlet transform is performed on face image to generate quadtree. then on the output of bandlet transform centre symmetric - local binary pattern (CS-LBP) is applied. A feature vector of the image is generated by taking the histogram of CS-LBP. the support vector machine (SVM) is used to classify expressions in six categories. the experiments are performed using a publically available CK+ dataset. the initial results with LBP and CS-LBP are reported.
Automated analysis of facial expressions is one of the most interesting and challenging problems in many areas such as human-computer interaction. Facial images are affected by many factors, such as intensity, pose an...

there are many cases, where the image processing is performed using the neural network First, for good patternrecognition, the analysis of the suitable network model is very important. thus, our goal in this work was to develop the simulator for the universal neural network analysis and on the base of this analysis to create the suitable neural network for the image processing. On the base of this network we have also designed some base circuits, which will be used for the future implementation of the neuron/network on the chip. the idea is to use it for more complex chip, used as the silicon retina in the *** instructions give you basic guidelines for preparing papers for conference proceedings.
