SQL Injection Vulnerability (SQLIV) is one of the topmost serious threats to web applications. Penetration test is one of the most important approaches to detect SQLIV. The test case generation issue critically affects the effectiveness of penetration test. Thus, research on the approaches to improve coverage and efficiency of test case generation process in SQLIV penetration test is of great importance...
SSD (Solid State Disk) is reconsidered as the next storage device, an alternative to the HDD (Hard Disk Driver). The read/write performance and energy consumption are main aspects to the users. In our experiment, we recognize that the performance and energy consumption of SSD, based on NAND Flash, are mostly related with the file system and block I/O scheduler. In order to gain higher performance...
Workflow simulation is a valid technique backing up process improvement. To this day, workflow model simulation is still a weak segment. Based on the research on workflow simulation technique, this issue carries out a way of business process simulation based on workflow, and offers the realization of workflow simulation mechanism supporting business process based on virtual running environment, finds...
The adsorption reduction mechanism and main chemical reactions were analyzed. After that, a Lean NOx Trap (LNT) model based on Simulink was constructed in this paper. Grounded on our calculation results, precisely control of the transition between rich and lean combustion mode was obtained. And also, the ratio of rich burn duration to lean burn duration had a significant effect on the NOx emissions...
In this paper, a small signal model of hysteretic current mode control with variable frequency and fixed hysteretic band is presented, based on three terminal averaged switch cell of buck converter in continuous current mode. This model reveals that the averaged current is the control target of hysteretic control. And phase lag of current loop with high switching frequency is quite small that makes...
One of the characteristics of ad-hoc networks is their mobility. What pattern each node moves will have a significant impact on the performance of ad-hoc networks. Through analyzing and comparing the performances of four mobility models such as RW, RPGM, FW, MH in sparse ad-hoc networks, it indicates that the impact on the performance of networks is remarkably different when the nodes move in different...
