In this paper, we study the optimal control problem for the demand-side of the smart grid under time-varying prices with general structures. We assume that users are equipped with smart appliances that allow delay in satisfying demands, and one central controller that makes energy usage decisions on when and how to satisfy the scheduled demands. We formulate a dynamic programming model for the control...
The paper introduces equipment of intelligent temperature detection of low-voltage arc-extinguishing chamber. The equipment is based on fiber grating sensor system. Temperature data of arc-extinguishing chamber are measured by experiment. Reducing electromagnetic interference by using fiber grating sensor in the temperature measurement. Data are analyzed by the finite element software, and plotted...
Analysis using ANSYS software, CSP component was reduced to two-dimensional model. In the thermal cyclic loading conditions using finite element simulating the stress and strain distribution of CSP components, obtained a dangerous solder joint of structural failure. The number of failure cycles about dangerous solder joint was predicted. Finally, introduced several analysis and evaluation method for...
An important problem in text mining is the automatic extraction of semantic relations. The paper provides a domain independent method for automatic extraction of part-whole relations in Chinese corpusa. The method consists of there phases. First, a set of lexico-syntactical patterns for part-whole relations are designed using known pairs of concepts encoding part-whole relations as seeds, and manually...
Measuring taxonomic similarity between words plays an important role in many semantic-based applications but still remains a challenging task today. We propose a new method which utilizes restrictive context matrices for this problem. We learn a set of special lexico-syntactic patterns automatically and use them to extract taxonomic related contexts of words from raw text. These restrictive contexts...
