The problem of automatically fall detection of older people living alone is a popular research topic since falls are one of the major health hazards among the aging population aged 65 and above and the population of them in China is more than 100 million. In this paper, we present an automatic human fall detection framework based on video surveillance which can improve safety of elders in indoor environments...
The Delay/Disruption Tolerant Network (DTN) is characterized with intermittently connectivity and frequent partitions. Due to this, the DTN routing algorithm is very vulnerable to various kinds of malicious attacks. In this paper, combined with many other DTN forwarding approaches, we propose a multi-stage routing forwarding algorithm so as to further improve network throughput. To ensure the security...
Through analysing many teachers' WebQuest works and discussing the defects that exist in the design and application of the WebQuest model. Aiming at these deficiencies give the corresponding strategies, also hoping that through improvement makes WebQuest better able to adapt to the network explorative study.
Virtual manufacturing is introduced to the production process of E-Blocks of computer disk drives, which mainly includes the technologies of digital modeling, computer simulation and structural optimization. The Secondary development technology of CAD (computer aided design) is used to improve the efficiency of digital modeling. The trial period is cut down after the FEM (finite element method) is...
Back-propagation neural network model was developed to predict the coal and gas outburst. After trained, the artificial neural network model was used to predict the coal and gas outburst of several samples. Moreover, ANN model was also used to analyse the quantitative effects of influencing factors on the coal and gas outburst. The prediction performance of ANN model is satisfactory. The prediction...
We have undertaken a thorough measurement and modeling study of IPTV CDN traffic. We have collected and analyzed network-layer IPTV CDN traffic measurements and, based on the characteristics of IPTV CDN traffic, a traffic model has been developed and verified with NS-2 simulation. Our simulation results indicate that the proposed traffic model complies well with the real IPTV CDN traffic. We detail...
Cellular networks and ad hoc networks have been widely deployed to provide many different services for mobile users. Due to their complementary properties, integrating networks of cellular networks and ad hoc networks are about to employed in commercial applications. Hence, secure authentication systems are vital to support this architecture. In this study, we propose a secure authentication scheme...
