Nowadays the Ad hoc network and WSN technologies are getting more and more public attentions and their applications increase rapidly and broadly. In this paper we present a mobile wireless network integration platform based on ARM9 and Linux OS which realizes the interconnection between WSN, ad-hoc network and TCP/IP network. The final results show that this platform realizes the expected goals and performs well in average time of response and transmit rate.
The 19th robotics program at the annual AAAI conference was held in Atlanta, Georgia, in July 2010. In this article we give a summary of three components of the exhibition: the Small-Scale Manipulation Challenge: Robo...

sciencecomputing environment dynamic construction based on virtualization technology can be benefit in performance isolation, on-demand creation and resource controls. This paper has focused on approach to sciencecomputing application environment provisioning based on virtualization technology. We propose a system model based on the features of sciencecomputing application and the key problem of provisioning is analyzed. Based on those works, a host capability rank strategy that can select the better performance host to deploy the virtual appliance is proposed. As the experiment shown, the algorithm can decrease the deployment time. As an additional result, we have observed that application runtime performance does have a linear increase on different application cases.

Sparse matrix-vector multiplication (SpMV) is the most important computational kernel, since its widely application in the scientific and engineering fields. In this paper, a series optimization methods of SpMV for CSR format have been approached. We focus on the underlying, paralleling and working set, and implement the library named as Combine Optimized SpMV for CSR format (COSC) which is the first CSR SpMV library combining with above optimization strategies and incorporates the optimizations such as explicit software pipelining, SIMDization, index compression, array padding and etc. Experiments show that the SpMV operation with optimization of COSC has average of 2.11 speedup while comparing with the non-optimized one. The implementation of COSC can be settled in SpMV and improve efficiency of hot spot.
