  • Theory for classifying equivalences of unified modelling language activity diagrams

    Publication Year: 2008, Page(s):391 - 403

    Despite the fact that there has been a wide adoption of unified modelling language activity diagrams (UML ADs) for software development, research focusing on the equivalence notions of UML ADs is scarce. To address this area of concern, the author presents a sound theoretical foundation for UML ADs. Through the use of these formal definitions of UML ADs, the author propounds a method which classif...

  • The π measure

    Publication Year: 2008, Page(s):404 - 416
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (412 KB)

    A novel software measure, called the pi measure, used for evaluating the fault-detection effectiveness of test sets, for measuring test-case independence and for measuring code complexity is proposed. The pi measure is interpreted as a degree of run-time control and data difference at the code level, resulting from executing a program on a set of test cases. Unlike other well-known static and dyna... View full abstract»

  • Implementing a software measurement program in small and medium enterprises: a suitable framework

    Publication Year: 2008, Page(s):417 - 436
    Cited by:  Papers (4)

    The successful implementation of software measurement programs is not an easy task. Software measurement program implementations sometimes fail, and this failure is frequently caused by their definition: the measurement program does not provide the required information, the data required are difficult to obtain and so on. The definition of measurement programs is even less encouraging in small and... View full abstract»

  • Software reliability allocation of digital relay for transmission line protection using a combined system hierarchy and fault tree approach

    Publication Year: 2008, Page(s):437 - 445
    Cited by:  Papers (8)

    Digital relay is a special purpose signal processing unit in which the samples of physical parameters such as current, voltage and other quantities are taken. With the proliferation of computer technology in terms of computational ability as well as reliability, computers are being used for such digital signal processing purposes. As far as computer hardware is concerned, it has been growing stead... View full abstract»

  • Conflict-aware schedule of software refactorings

    Software refactoring is to restructure the internal structure of object-oriented software to improve software quality, especially maintainability, extensibility and reusability while preserving its external behaviours. According to predefined refactoring rules, we may find many places in the software where refactorings can be applied. Applying each refactoring, we may achieve some effect (quality ...

  • Types for task-based access control in workflow systems

    Publication Year: 2008, Page(s):461 - 473
    Cited by:  Papers (2)

    Task-based access control (TBAC) is a flexible security mechanism, which has been widely implemented in workflow management systems. In TBAC, permissions are assigned to tasks and users can only obtain the permissions during the execution of tasks. The authors aim at developing a method for formalising and analysing security properties of workflow systems under TBAC policy. To achieve this goal, t... View full abstract»
