Recognising and understanding the activities performed by people is a fundamental research topic in developing a wi de range of applications that would be societally beneficial. In this article, we present and discuss two research projects on human action recognition based on computer vision techniques. We also report an ongoing research project that focuses on learning human activities through low...
Sensitivity of soil erosion is the representative of the possibility of occurring soil erosion under natural conditions. Sensitivity evaluation of soil erosion is the reliable method to identify the highly sensitivity areas and evaluate the sensitivity degree in a particular area. This paper uses the revised universal soil loss equation (RUSLE) and GIS technique which has powerful space analysis functions...
In PaaS, the issue of resource provisioning becomes more challenging because a great number of applications share and compete for resources simultaneously. PaaS platform should be able to maximize the resources utilization, while satisfying the performance requirements of all applications. However on-line request workload can be fluctuated during the run time of applications and static resource allocation...
In order to ensure the security of the sharing service in grid, a dynamic authorization model based on trust mechanism is presented, which is based on role-based access control. In the model authorization is obtained while the trust worthiness of the bargainers exceeds the trade threshold; it also introduces the concepts of task and condition into the authorization model so that it can achieve dynamic...
By analyzing the problem of the current monitoring system, the design solutions of the integrated remote monitoring system based on Internet / GPRS is proposed. The system is integrated multiple monitoring ways and it can monitor multiple locations simultaneously. By phone software, short message and Web browser, users can view video, temperature and humidity, smoke, infrared intrusion and other information...
For the purpose of enhance the security of poor working in coal mine, it's important to study on the problem of location and tracking for keeping mining personnel and down hole equipments safe. We put forward wireless sensor network underground location algorithm which is based on the superposition of RSSI and DV-Hop. This algorithm makes up for the shortage of RSSI algorithm and DV-Hop algorithm...
