In order to evaluate the operational efficiency of the Internet Company in China, this paper constructed the index system of the efficiency evaluation at first. Then we appraise the overall efficiency and variation tendency about Internet Company of China Based on DEA method from cross section data and temporal patterns. At the same time this paper classifies the Internet Company into three typ...

In order to support the real-time collaboration between geographically distributed designers, the single-user application AutoCAD is required to be transformed transparently into groupware system by adopting fully replicated architecture. As the core issue to maintain the consistency of the distributed replicas, traditional consistency maintenance algorithms (such as Operation Transformation an...

Analog integrated circuit testing and diagnosis is a very challenging problem. The inaccuracy of measurements, the innnite domain of possible values and the parameter deviations are among the major diiculties. During the process of optimizing production tests, Monte Carlo simulation is often needed due to parameter variations , but because of its expensive computational cost, it becomes the bot...

Web information extraction, in particular web news extraction is an open research problem and it is a key point in NewsIR systems. Current techniques fail in the quality of the results, the high computational cost or the necessity of human intervention, all of them critical issues in a real system. We present an automated approach to news recognition and extraction based on a set of heuristics ...

Eight provinces in Thailand’s south tourism-related airports are expected to push for more significant airport expansion. In response the expansion of tourism industry each province southern region and increasing use services from people neighboring areas, problem eight consists inefficiency operating systems service management. The construction infrastructure projects that do not meet needs us...

The aim of this study is to perform a dynamic modelling and simulation of a Portuguese industrial integrated system in order to analyse the integration and feasibility of the different units, maximizing its efficiency and minimizing its environmental damage, and to study the effect of some operational and atmospheric conditions on the system. For this purpose it was built a dynamic model of the...
