The rapid development phases and extremely short turnaround time of Web applications make it difficult to eliminate their vulnerabilities. Here we study how software testing techniques such as fault injection and runtime monitoring can be applied to Web applications. We implemented our proposed mechanisms in the Web Application Vulnerability and Error Scanner (WAVES)-a black-box testing framework for automated Web application security assessment. Real-world situations are used to test WAVES and to compare it with other tools. Our results show that WAVES is a feasible platform for assessing Web application security. (c) 2005 Elsevier B.V.

We use an optimization technique to accurately locate a distorted grid structure in a microarray image. By assuming that spot centers deviate smoothly from a checkerboard grid structure, we show that the process of gridding spot centers can be formulated as a constrained optimization problem. The constraint is equal to the variations of the transform parameter. We demonstrate the accuracy of our algorithm on two sets of microarray images. One set consists of some images from the Stanford Microarray Database; we compare our centers with those annotated in the Database. The other set consists of oligonucleotide images, and we compare our results with those obtained by GenePix Pro 5.0. Our experiments were performed completely automatically.
