In this paper we introduce SeTGaM, a Model-Based Regression Testing (MBRT) approach based on UML/OCL behavioral models. SeTGaM is a test selection and classification approach that also generates new tests to cover new functionalities of a new version of a system. We extract the behavior of the system from guards/transitions of state charts or pre/post conditions in operations of class diagrams to...
Summary form only given. Magneto-hydrodynamic simulations provide a powerful tool for improving our understanding of the complex physical processes underlying the behavior of wire array Z-pinches. With the advent of large scale parallel computing and three dimensional models, it is now becoming possible to model the entire plasma volume with sufficient resolution to capture the important physical...
Summary form only given. Development of a predictive computational model for wire array z-pinches has been inhibited by the 3D nature of the dynamics. We have developed a 3D computational model for simulating cylindrical wire array z-pinches. In lieu of trying to simulate individual wires in the array from the beginning of the initiation phase, which is computationally impractical, we have incorporated...
