In online model-based testing, test execution is interleaved with test generation. Test cases should be generated and executed with minimal delay, while still achieving targeted coverage criteria quickly. Extensive model analysis in such case is not possible as any delays in choosing the next step will immediately impact the response times of test execution. The algorithms thus need to be as fast...
Combinatorial test design model consists of parameters, values and the associated constraints. This model is the input for test generators. In this paper we present a rule based approach for deriving combinatorial test design model from UML activity diagrams resulting from requirement analysis. We have explored this approach on few sample cases. Our initial results suggest that this automated approach...
Stochastic simulations are often sensitive to the source of randomness that characterizes the statistical quality of their results. Consequently, we need highly reliable Random Number Generators (RNGs) to feed such applications. Recent developments try to shrink the computation time by relying more and more General Purpose Graphics Processing Units (GPGPUs) to speedup stochastic simulations. Such...
Atmospheric effects are one of the important factors that affect the physical realism of the infrared (IR) scene generators. IR scene generators obtained by OpenGL library are used in the applications where performance is critical. Modeling atmospheric effects in the IR band using OpenGL's fog model approach is found in the literature. However, the related fog model needs parameters that are independent...
Present and future semiconductor technologies are characterized by increasing parameters variations as well as an increasing susceptibility to external disturbances. Transient errors during system operation are no longer restricted to memories but also affect random logic, and a robust design becomes mandatory to ensure a reliable system operation. Self-checking circuits rely on redundancy to detect...
MPSS simulates the behavior of a high traffic transaction processing system. An effective use of MPSS is the analysis of the impact of exclusive control of system resources over multiple processes. MPSS consists of a control process and multiple application processes. The control process is designed to simulate a transaction processing monitor. It initiates and oversees multiple application processes...
