Power transformer is one of the key electrical apparatus in power system and its reliability has directly correlation on the safety of power system. this paper presents anomaly recognition method of oil chromatographic data based on distributed computing, aiming at the existing problems that the study fails to use abnormal features of oil chromatographic data effectively to identify the abnormal and lack of the problem of identifying method for massive data anomaly. First, obtain the characteristics of abnormal data through the analysis of a large number of oil spectrum anomaly data sequence. then, Form anomaly recognition method. the method uses abnormal features of oil chromatographic data as judgment index of abnormal mode. If any abnormal pattern is met, the abnormal data can be identified. Abnormal recognition of transformer oil chromatographic data is realized on distributed computing platform. Accuracy rate of anomaly recognition is up to 89.3%. Experimental results show that this method is accurate and can be applied to distributed computing platform.

the B-Spline curve and surface provide an accurate tool to record object shape. We present a biometric identification system through hand geometry measurements by using B-Spline curves. We use 4 B-Spline curves to fit with fingers (except thumb) from a single hand image for a single person. then we store these 4 curves as well as other geometry measurements of the hand as the "signature" of that person into the database. By computingthe differences between the curves from database hand images and the curves from the query hand image using the point projection method, we are able to verify/identify the person by locating the closest database hand image to the query hand image.

this paper presents a novel approach for behavior recognition from video data. A biologically inspired action representation is derived by applying a clustering algorithm to sequences of motion images. To obey the temporal context, we express behaviors as sequences of n-grams of basic actions. Novel video sequences are classified by comparing histograms of action n-grams to stored histograms of known behaviors. Experimental validation shows a high accuracy in behavior recognition.

We have theoretically shown that multiferroic nanomagnets (consisting of a piezoelectric and a magnetostrictive layer) could be used to perform computing while dissipating similar to few 100 kT/bit at clock rates of similar to 1GHz [1,2,3]. they can act as memory elements [2], binary logic gates [3, 4] and associative memory for four state logic [5, 6]. the latter enables signal processing functions such as ultrafast image reconstruction and patternrecognition [7]. this talk will provide an overview of our research in modeling stress induced nanoscale magnetization dynamics, its application to ultra low energy hybrid spintronic/straintronics memory and information processing, and discuss preliminary experimental work in fabrication and experimental demonstration of these devices.

Scientific evidence has shown that long-term sedentary behaviour is detrimental to human health. therefore, a trend appears in the field of healthy lifestyle promotion that more attention is drawn to sedentary behaviour rather than only physical activity. However, technology-based mobile health intervention tools targeting reducing sedentary behaviour are still lacking. this paper aims to explore a solution for sedentary behaviour change through supporting action planning. Action planning can not only bridge the intention-behavior gap in controlled motivation processes, but also enforce the cue-behavior association in unconscious processes. We present a smartphone-based personal mobility pattern visualization, with which we expect the users can make better action plans. the interactive visualization integrates temporal and spatial patterns of personal sedentary and walking behaviour, to provide explicit hints on when, where, and how to reduce sedentary behaviour and increase daily steps. We also present our experimental design to evaluate the visualization-based intervention tool.

there are four main problems that limit application of patternrecognition techniques for recognition of abnormal cardiac left ventricle (LV) wall motion: 1) Normalization of the LV's size, shape, intensity level and position;2) defining a spatial correspondence between phases and Subjects;3) extracting features;4) and discriminating abnormal from normal wall motion. Solving these four problems is required for application of patternrecognition techniques to classify the normal and abnormal LV wall motion. In this work, we introduce a normalization scheme to solve the first and second problems. Withthis scheme, LVs are normalized to the same position, size, and intensity level. Using the normalized images, we proposed an intra-segment classification criterion based on a con-elation measure to solve the third and fourth problems. Application of the method to recognition of abnormal cardiac MR LV wall motion showed promising results.
