Sensing coverage is a fundamental problem in sensors networks. Different from traditional isotropic sensors with sensing disk, directional sensors may have a limited angle of sensing range due to special applications. In this paper, we study the area coverage problem in directional sensor networks with the rotatable orientation for each sensor. We propose the optimal coverage in directional sensor networks...
Network Video Monitoring has been developed in the embedded field, however, current video surveillance is too expensive to limit use widely. The paper proposes a new method that ARM9 processor is hardware platform and embedded Linux system is software development, with USB camera as video gather. Using TCP/IP agreement realize network communication. The system inside embeds Web server so users can...
Based on the linear polarization method and the weak polarization method, a new on-line monitoring system for metal corrosion was developed, and the metal corrosion rate and polarization resistance was on-line measured and real-time displayed. Compared with the result obtained with a constant potential meter, the monitoring system have many advantages, such as stable performance, prompt measuring...
Business user oritented business process monitoring plays a key role for enterprises to improve business processes' visibility and responsiveness. Usually an end-to-end business process is implemented by heterogenous technologies and their combinations in a SOA enviroment, for instance: business process execution language (BPEL), J2EE and any other technologies which can leverage Web service as composition...
The lead-time for the retailer's inventory system may be changed with different suppliers in chinapsilas low technology industries. A multi-agent simulation system is proposed to simulate this category of dynamic supply chain. In the simulation system, the retailer's stock was controlled by (S, s) policy, and then four categories of supply chain scenarios were suggested. Four propositions were achieved...
