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...
Texture is an important property of fire smoke, which is a significant signal for early fire detection. This paper describes a method of analyzing the texture of fire smoke combining two innovative texture analysis tools, Wavelet Analysis and Gray Level Cooccurrence Matrices (GLCM). Tree-Structured Wavelet transform is used to represent the textural images and GLCM are used to compute the different...
Distributed software systems are characterized by increasing autonomy. They often have the capability to sense the environment and react to it, discover the presence of other systems and take advantage of their services, adapt and re-configure themselves in accordance with the internal as well as the global state. Testing this kind of systems is challenging, and systematic and automated approaches...
A generic test process should support all approaches "formal to informal" and mixed approaches within, and across, all test levels. But widely-accepted formal approaches, from current standards, certification syllabi and tools, have explicitly-defined test cases as the key underlying entity: not all real-life approaches use explicit test cases. Also, testing is maturing beyond merely "finding...
Due to the continuously growing possibilities provided by technology and its wider application, today's IT products are becoming more and more complex both from technical and managerial standpoints. Very often, multiple parties are involved in their development. Consequently, the organization of the integration and testing of these products gets increasingly complex. Organisations already encounter...
Software security testing tools and methodologies are presently abundant, and the question no longer seems to be "if to test" for security, but rather "where and when to test" and "then what?". In this paper we present a review of security testing literature, and propose a software security testing scheme that exploits an intra-organisational repository of discovered...
An important issue to the adoption of any enterprise architectural approach is the availability of tools to support the development, storage, presentation, analysis, improvement and evolution of enterprise architecture representations. As with enterprise architecture methodologies, enterprise architecture tools to support the architectural development process are still emerging. Most important software...
