In this paper, we present an architecture-based approach for modeling software reliability. Our approach aims at modeling reliability on various software infrastructures and in any stage of software life cycles. To this end, we utilize characteristics of architectural styles to capture non-uniform behaviors of software embodying heterogeneous architecture.(More)
We present a dependence model based on which an efficient slicing algorithm is applied to compute forward slices for impact analysis and for regression test selection. The dependence model not only captures control and data dependence relationships, but also depicts dependence between components and their execution contexts. The model is constructed in a(More)
Component-based software development facilitates software reuse and promotes productivity and quality. Although much work has been proposed for building component-based systems, techniques of testing component-based systems have not been well developed. In this paper, we present a technique for component-based software in integration testing. Our approach(More)
OBJECTIVES The purpose of this study was to determine the sonographic performance in pathologically proven cases of nasopharyngeal carcinoma and its involvement in the parapharyngeal space. METHODS The study included 58 patients being treated for suspected nasopharyngeal carcinoma detected by routine nasopharyngoscopy who underwent pathologic biopsy.(More)
