Risk assessment is the base of software project risk management. According to risk assessment's objective and correlative literatures analysis, the risk assessment's criterion system is established in the paper. Then fuzzy linguistic multiple attribute decision making method is utilized to assess software project risk. The method estimates risk criteria values using linguistic terms based on triangular...
This paper discusses the methods of how to use the virtual instrument to dynamically demonstrate the physical processes. Applying the virtual instrument technique to physics demonstration experiment, using virtual instrument and multimedia technologies to physics demonstration experiment teaching , especially demonstrate some dynamic process of the physical experiment with this method solves the problems...
The design of the multifunctional portable vehicle tail gas detection system adopts virtual instrument technology based on computer. It utilizes portable computer and USB data collecting card to control the detection. So it can detect and record the vehicle tail gas in wide range accurately, and can count and analyze the component and content of the harmful gas. This system has such advantages as...
When targets fall in different types of clutter and noise background in High Frequency Surface Wave Radar (HFSWR), uniform detection algorithms always result in poor detection and tracking performances. To solve the problem, two methods are proposed in this paper by extracting the background features according to the probability distribution and the image characteristic of the spectrum map. The first...
