Dynamic changes to an architecture is an active area of research within the software architecture community. Architectures must have the ability to react to events and perform architectural changes autonomously. In this paper, we focus on dynamic architectures reconfiguration. Our principle is to use the agent architectural concept to achieve this functionality with respect to some quality attr...

Looking from an historical perspective, it can be seen that many civilizations have lived in the country and consequently produced many different cultures and architectural products. One of the oldest cities which contain such historical examples which have lived until present is Tabriz. Its traditional houses are the most important places to represent the life style of the past. Lack of recogn...

The integrity of complex software systems built from existing components is becoming more dependent on the integrity of the mechanisms used to interconnect these components and, in particular, on the ability of these mechanisms to cope with architectural mismatches that might exist between components. There is a need to detect and handle (i.e. to tolerate) architectural mismatches during runtim...

Cybersecurity attacks are a major and increasing burden to economic and social systems globally. Here we analyze the principles of security in different domains and demonstrate an architectural flaw in current cybersecurity. Cybersecurity is inherently weak because it is missing the ability to defend the overall system instead of individual computers. The current architecture enables all nodes ...

The strategic role of IT and its significance throughout the organization increases complexity, variety, and the need of change. Hence IT management must deal with uncertainties derived from different, conflicting and ever changing demands. In this sense Enterprise Architecture is playing an increasingly important role in improving IT management practice. If contemporary organizations do not su...

the feature of decorating curves in iranian arts, paintings, illumination, cover decorating, engraving carving sudoriferous cloth carpet and several decorations related to architecture including tile, stucco have principles and features of traditional designing. several types of figures of khatayi and ieslimi and their roles in combination and space besides having principles in proportion to gr...

This paper addresses the general area of computer architectures for safety-critical real-time applications. The maximum acceptable probability of failure for these applications ranges from about I O 4 to 1Oi0 per hour depending on whether it is a military or civil application. Typical examples include commercial and military aircraf fly-by-wire, full authority engine control, satellite and laun...

The paper introduces the formal description of a computing multi-agent system (MAS), its architecture and dynamics (sections 2–4). The optimal scheduling problem for the MAS as well as a way of its verification are presented in terms of such a model (section 5). A brief report of test results published previously in [13, 3, 4, 8] is contained in the section 6.

Intramembrane proteases hydrolyze peptide bonds within the membrane as a signaling paradigm universal to all life forms and with implications in disease. Deciphering the architectural strategies supporting intramembrane proteolysis is an essential but unattained goal. We integrated new, quantitative and high-throughput thermal light-scattering technology, reversible equilibrium unfolding and re...

The transmission and central representation of sensory cues through the accurate construction of neural maps is essential for animals to react to environmental stimuli. Structural diversity of sensorineural maps along a continuum between discrete- and continuous-map architectures can influence behavior. The mechanosensory lateral line of fishes and amphibians, for example, detects complex hydro...
