Bayesian network (BN) classifiers with powerful reasoning capabilities have been increasingly utilized to detect intrusion with reasonable accuracy and efficiency. However, existing BN classifiers for intrusion detection suffer two problems. First, such BN classifiers are often trained from data using heuristic methods that usually select suboptimal models. Second, the classifiers are trained using...
Applications with a Graphical User Interface (GUI) front-end are ubiquitous, thus it is of great importance to assure the quality of such systems. Model-based GUI testing provides an effective mechanism for automated testing of applications with a GUI. However, most existing model-based GUI test generation techniques produce many infeasible (i.e., Broken) event sequences which are used as test cases...
Automated web service composition can largely reduce human efforts in business integration. We present an approach to fully automate web service composition without workflow or knowing the semantic meaning of atomic web service. The experiment results show that the accuracy of our composition method using Genetic Programming (GP), in terms of the number of times an expected composition that can be...
An important goal of automatic testing techniques, including random testing is to achieve high code coverage with a minimum set of test cases. To meet this goal, random testing researchers have proposed many techniques to generate test inputs and method call sequences that yield higher code coverage. However, most proposed random testing techniques are only suitable for toy systems, and they achieve...
A clock distribution scheme based on a zero-phase-clock-buffer (ZPCB) is presented. Each ZPCB generates an equal phase between its input and output by adjusting its resonant frequency to slightly higher than the clock frequency. A testchip fabricated in a 40 nm LP process measures sub-psec skew over 500 MHz and 800 MHz ranges, for a 5 GHz single-ended and a 15 GHz differential ZPCB, respectively.
