Recent works in ubiquitous computing have addressed analysis of electric power for energy conservation by detailing and studying consumption of electrical appliances. We contribute with an approach to develop techniques for fingerprinting and monitoring consumption of electric power in households. The approach builds on previous works and employs three phases: feature extraction of attributes such as real power and current harmonic contents, event detection and patternrecognition. A load library is foreseen that stores appliance characteristics as corpus data for training and recognition. We report early findings achieved using a high definition sensor directly applied to the loads showing promising results but also challenges in event detection (smaller state transitions, challenges in detecting and pairing switch on and off events). These studies are important in order to be able to address opportunities of identifying and monitoring directly at the appliance level or sensing the total load of the network. Future applications include monitoring and detailing of loads in a "balance sheet" and context aware service with advice tips for energy users.
Extended fingerprint features such as pores, dots and incipient ridges have been increasingly attracting attention from researchers and engineers working on automatic fingerprint recognition systems. A variety of meth...

Real-time syntactic pattern recogniton imposes strict computing time constraints on new techniques developed. Recently, a method for an analysis of hand postures of the Polish Sign Language based on the ETPL(k) graph grammars (Flasinski: Patt. Recogn. 26 (1993);1-16;Theor. Comp. Sci. 201 (1998), 189-231) has been constructed. In order to make a system implemented more feasible for the users, a research into parallelization of a patternrecognition process has been led. Possible techniques of tasks distribution have been tested. It has allowed us to define an optimum strategy of parallelization. The results are presented in the paper.

Array-type tactile sensor is important for manipulating objects dexterously with a robotic *** have developed Universal Robot Hand with tactile sensors and other sensors, and proposed the genetic based tactile measurement in order to measure the tactile information efficiently. However, multicontact condition can not be recognized with this method. This paper proposes a multi-contact recognition method with arraytype tactile sensor for multiple objects manipulation. The validity of the proposed method shows through some experiments.
This paper presents a novel local feature descriptor, the Local Directional pattern (LDP), for recognizing human face. A LDP feature is obtained by computing the edge response values in all eight directions at each pi...

Technology Innovation has become the principal method for enterprises to survive in the competitive economic environment. This paper, by using the Product Life Cycle Theory, discusses the different technology innovation patterns that enterprises can adopt at different stages of the product life cycle. The paper thus develops a number of technology innovation strategies under those different patterns and further summarizes the choice factors that influence technology innovation patterns.
A new iris recognition system based on Wavelet Packet Analysis is described. The most unique phenotypic feature visible in a person's face is the detailed texture of each eye's iris. The visible texture of a p...

Finger vein patternrecognition is a biometric modality that uses features found in the blood vessel structure of the fingers. Vein pattern images are captured using a specialized infrared sensitive sen-sorsor which due to physical properties of the hemoglobin present in the blood stream give rise to a slight intensity difference between veins and tissue. We investigate five different contrast enhancement algorithms, which range from high to low computational complexity, and evaluate the performance by using five different quantitative contrast measuring methods.
Over the recent years, a great deal of effort has been made to age estimation from face images. It has been reported that age can be accurately estimated under controlled environment such as frontal faces, no expressi...
