This study focuses on special requirements on MOOC adoption of Chinese higher education student group (CHESG). Firstly the factors that will affect MOOC adoption of CHESG are analyzed based on the technology adoption model (TAM). Then structural equation model is built, and ten hypotheses are proposed. In the model, the correlations between perceived usefulness, perceived reputation, willingness to...
The Wireless Sensor Converge-cast Networks (WSCNs) are widely applied in many fields such as medical applications and environmental monitoring. The monitoring data are collected from the sensors and gathering toward the sink node. A coding aware routing scheme based on Connected Dominating Set is provided. Based on CDS, a coding condition, named Improved Coding Conditions (ICC), is defined with an...
In this pilot study, we have (i) examined the relative importance of ten factors that can be used for developing new training methods and materials to improve employees' awareness and skills to defend against cyber risks, and (ii) investigated the relationship between an explicit security policy at the organizational level and individual employee's behavior and beliefs toward cybersecurity issues...
Relying on the background of large section soil tunnel engineering, the numerical simulation on three excavation methods for soil tunnel including bench method, arch heading method and cross diaphragm were carried out. Results show that the arch heading method is confirmed as optimum for this project by comparative analysis. And then, according to the monitoring results of the arch heading method,...
The choice of locations for logistics facility has an influence not only on logistics cost but also on the level of customer service. However, traditional facility location models all lay emphasis on logistics cost and ignore the service level. To overcome this inefficiency, by considering the level of customer service, logistics facility location model based on reliability is presented. Then, a numerical...
The increasing speed mismatch between storage device and processor has fueled a search for new storage structures and retrieval mechanisms. This paper describes the design and prototype implementation of RSC, a reliable high-performance clustered storage system for multimedia applications. To achieve high reliability, we adopt a novel hierarchy management method to ensure the metadata security and...
MANET (mobile ad hoc network) is a collection of wireless mobile nodes forming a temporary communication network without the aid of any established infrastructure. Because mobile nodes are typically constrained by power and computing resources, a selfish node may not be willing to use its computing and energy resources to forward packets that are not directly beneficial to it, even though it expects...
The reliability can be enhanced by using single-phase reclosing, but when reclose to permanent faults, it is another surge on system. So there is necessity to study on the influence of reclosing sequence on transient stability margin. In the case that transient and permanent fault is not effectively identified, the influence of sequence and time of single-phase reclosing on transient stability margin...
