POST was developed cooperatively by the Purple Mountain Observatory and the National Astronomical Observatory of Japan from 1997 to 2000 [1]. Performance degradation occurred in the POST system after years of operation. So a through upgrade was carried out in 2014, which include hardware and software of the control system, servo system, bias supply power, chopper wheel, weather station, etc. The updated...
Test suite reduction aims at adequately testing all the test requirements with the least number of test cases. Through the coverage relationship between test requirements and test cases, test suite reduction problem can be converted into the standard optimization problem. Quantum evolutionary algorithm (QEA) is an intelligent algorithm based on quantum computation . In QEA, chromosomes are encoded...
Focusing on the software security risk assessment, this paper adopts the combination of the attack tree model analysis and the Bayesian Network analysis, which takes the advantage of both qualitative analysis and quantitative analysis to assess risks of software security. By the construction and pruning of the attack tree model, this method narrow down the scope of threats that are generated by software...
This article uses the graphics designer and the code editor of GL Studio combined with VC++6.0 to simulate the instruments which is based on a certain type aeroboat. This paper introduces the GL Studio software, its main function and its application in aeroboat simulation. This simulation result can real-timely shows the parameters (speed, altimeter and electrical quantity) of the aeroboat, and it...
As a newly software delivery model, software as a service, SaaS for short, is the best way for small and medium enterprise to adopt the newly technology. However trustworthiness is greatest challenge in the wide acceptance of SaaS. In the absence of trustworthiness in SaaS applications, data privacy is the primary and the most important issue for tenants. How to protect the data privacy when software...
