For commercial software in scientific and engineering computing,software licenses are needed when running them in high performance computing ***,there is a constraint for the number of software *** the traditional software licenses management approaches,there is a prominent *** jobs will fail immediately without available software ***,the existing job scheduling mechanisms mainly focus on hardware resources *** this paper,we propose a software licenses aware job scheduling and management approach on multi-clusters,which is a common scenario for current high performance computing *** on floating licenses and scheduling policies,the submitted jobs from multi-clusters requiring software licenses will be uniformly queued and scheduled.A co-scheduling mechanism is provided for the software licenses and hardware *** software and limited licenses can be shared and used efficiently on *** implemented and evaluated the approach in a real multi-clusters computing environment.

CVaR has more advantages, than the VaR as portfolio risk measurement tool, but with the calculation of VaR, the Monte Carlo simulation method of the CVaR is difficult, and the cost is high. The establishment of the system of distributed parallel algorithm can reduce costs and speed up the calculation, which is conducive to the promotion of the CVaR Monte Carlo algorithm.

firstly, the skewed image of examination paper is corrected by Hough transform, and then mathematical morphology methods are used to locate the frame lines in table. Then connected component analysis is utilized to locate the form region based on maximum area feature. Finally the form frame line is removed according to the vertical gradient, and the answer image is achieved by analyzing the coordinates of objects.

Semantic web is the future realization of the current web,in which resources are annotated with machine understandable meta-data,allowing the automation of tasks by employing these resources in their correct *** notable technologies have been specified by the World Wide Web Consortium(W3 C) for the application development lifecycle of semantic *** worldwide adoption of these technologies requires the development of secure semantic web *** the research community has proposed to define and integrate security standards to all phases of semantic web application *** this purpose the research community has reported some of the preliminary efforts in the form of XML Key Management(XKMS),Security Assertion Markup Language(SAML),XML Access Control Markup Language(XACML) and Platform for Privacy Preferences(P3 P).But there is a need to develop a security assessment benchmark for semantic web *** effective assessment of security of semantic web applications has been paid less attention so far in this *** this reason in this research work we propose some important features related to the development of a benchmark for secure semantic web application development that can effectively assess security of semantic web applications based on the survey of the security aspect of important semantic web languages ***,RDF,OWL and SPARQL/*** aim of the benchmark is to facilitate developers in building secure semantic web applications and provide security professionals to develop sophisticated security tools by effective performance evaluation.

This article summarizes the architecture and the characteristic of Flex technology as well as its advantage in handheld devices design, proposed the system framework of the handheld terminal based on Flex. Combined with the NewMap Server, using the RIA SDK and Flash AIR technolygy, map display on handheld devices is realized. Project experience justifies that appliction software based on Flex used in handheld terminals has an advantage of crossplatform.

Analysis of open type wharf berthing condition is a complex process. It is hardly to simulate the environment and test results, which are consistent with the actual situation with physical model. In this paper, ship-mooring test during mooring is conducted applying the Large Ship Maneuvering Simulation Platform on the basis of the hydrological, meteorological and underwater terrain data. Combined with actual situation and the experience since the dock put into operation, the safety ship mooring conditions and safety berthing measures during mooring are determined.

Pedestrian detection is a significant task in driver assistance systems. This paper presents an in-vehicle system for pedestrian detection. To speed up computation, we parallel implemented the state of the art detection algorithm on a NVIDIA GPU. The experiments demonstrate that our implementation can achieve accurate and real time detection.
