 ABSTRACT 

Memory space for storing the power quality signal are major concern due to penetration of novel power sources and highly sensitive loads in modern power system. Wavelet based data compression approach is presented in this paper for the automatic data reduction and signal analysis. Real time data of power quality signals have been processed with IEEE Power quality wave data, to deal with practical implementation. The method proposed, which can be processed in real-time, showing the potential in data reduction and accurate characterization of voltage power quality signal in power systems . 

KEYWORDS 

Power quality signals, Data compression, Wavelet analysis, Real time monitoring, Wavelet energy coefficient

AUTOMATIC CLASSIFICATION OF INSECTS USING COLOR-BASED AND SHAPE-BASED DESCRIPTORS  Siti N. A. Hassan, Nadiah S. A. Rahman, Zaw Zaw Htikeand Shoon Lei Win   Faculty of Engineering, IIUM, Kuala Lumpur, Malaysia  ABSTRACT  Entomology has been deeply rooted in various cultures since prehistoric times for the purpose of agriculture. Nowadays, many scientists are interested in the field of biodiversity in order to maintain the diversity of species within our ecosystem. Out of 1.3 million known species on this earth, insects account for more than two thirds of these known species. Since 400 million years ago, there have been various kinds of interactions between humans and insects. There have been several attempts to create a method to perform insect identification accurately. Great knowledge and experience on entomology are required for accurate insect identification. Automation of insect identification is required because there is a shortage of skil...
