1. ABS~CT Tradition image retrieval methods use primq fea~, such as coIour, shape and tetie, in indetig and retrieval. However, Mteratia and our e~eriment show that no one feature can perform consistently over a variety of imagw. Some aspects of the images have not been eqloited. We propose a-feature using geometrid @don) transform for the stiarity(More)
A Mobile Wireless Sensor Network consisting of a large amount of tiny sensors with low-power can be an effective tool for gathering data in a variety of environments. The data collected by each sensor is transmitted to a single processing center that uses all data to determine characteristics of the environment. Sensors deployed in all kinds of areas on a(More)
This article focuses on the object-oriented software process. It compares three most popular software processes: RUP (Rational Unified Process), OPEN (Object-oriented Process, Environment and Notation), and OOSP (Object-oriented software process); then it carries out an Enhanced RUP based on the advantages of OPEN and OOSP. By setting up a simple model, it(More)
1 Project Description Software defined radio (SDR) is quite useful as a flexible implementation of WLAN transceiver in wireless networks. It provides a programmable testbed for innovations in both Medium Access Control (MAC) and physical (PHY) layer network protocols, whereas traditional simulation based method is considered broken in terms of its reality.(More)
It is difficult for security experts to generate polymorphic signatures by using traditional string mining and matching techniques. A semantic-aware method is presented to generate a kind of two-level signature that includes both polymorphic semantics and string patterns. It first analyzes the characteristics of polymorphic engines and categorizes the data(More)
