In industry, software testing and coverage-based metrics are the predominant techniques to check correctness of software. This paper addresses automatic unit test generation for programs written in C/C++. The main idea is to improve the coverage obtained by feedback-directed random test generation methods, by utilizing concolic execution on the generated(More)
Program analysis using abstract interpretation has been successfully applied in practice to find runtime bugs or prove software correct. Most abstract domains that are used widely rely on convexity for their scalability. However, the ability to express non-convex properties is sometimes required in order to achieve a precise analysis of some numerical(More)
Software model checking and static analysis have matured over the last decade, enabling their use in automated software verification. However, lack of scalability makes these tools hard to apply. Furthermore, approximations in the models of program and environment lead to a profusion of false alarms. This paper proposes DC2, a verification framework using(More)
C++ Exceptions provide a useful way for dealing with abnormal program behavior, but often lead to irregular interprocedural control flow that complicates compiler optimizations and static analysis. In this paper, we present an interprocedural exception analysis and transformation framework for C++ that captures the control-flow induced by exceptions and(More)
Modern object-oriented programming languages such as C++ provide convenient abstractions and data encapsulation mechanisms for software developers. However, these features also complicate testing and static analysis of programs that utilize object-oriented programming concepts. In particular, the C++ language exhibits features such as multiple inheritance,(More)
The activity of the lateral pterygoid muscle has been regarded to be related to the pathological condition of the temporomandibular joint (TMJ) in the craniomandibular disorders. Because the lateral pterygoid muscle is a deep muscle, a needle electrode is necessary for EMG recordings. The purpose of this study was to establish a non-invasive method for the(More)

BACKGROUND Sandblasting particles which remain on the surfaces of dental restorations are removed prior to cementation. It is probable that adhesive strength between luting material and sandblasting particle remnants might exceed that with restorative material. If that being the case, blasting particles adhere to sandblasted material surface could be(More)
