Software Architecture modeling and representation is very important in software development process. Software Architecture provides high level view which is very useful in all phases of software life cycle. Component based software architecture is beneficial as it is useful for reusing system parts represented as components. Most of the existing object oriented systems do not have reliable soft...

During the last decade the continuous growth of the Web resulted in a significant development shift from simple types of software applications to distributed multi-tier web-based applications. In general, distributed systems are by nature more complex than centralized systems. As a result, the software engineering tasks of these systems are also complicated. Unlike traditional software applicat...

Pervasive computing can be defined as access to information and software applications anytime and anywhere. This form of computing is highly dynamic and disaggregated. Users are mobile and services are provided by collections of distributed components collaborating together. Recent advances in mobile computing, service discovery, and distributed computing are key technologies to support pervasi...

In order to reuse software, there needs to be software to reuse." One of the dilemmas that has prevented software developers from reusing software is the lack of software artifacts to use or the existence of artifacts that are di cult to integrate. Domain Speci c Software Architectures (DSSAs) have been proposed in order to address these issues. A DSSA not only provides a framework for reusable...

A framework for the next generation machinery monitoring and diagnostic systems is being addressed through the OSA-CBM development team. This framework employs the use of an open system architecture standard that uses a distributed software model approach. A distributed software model was selected due to the recent emergence of enabling software technologies and the benefits of the approach. In...

quantitative and model-based prediction of security in the architecture design stage facilitates early detection of design faults hence reducing modification costs in subsequent stages of software life cycle. however, an important question arises with respect to the accuracy of input parameters. in practice, security parameters can rarely be estimated accurately due to the lack of sufficient kn...

This paper describes the architecture fo r the distributed CAPS system (DCAPS). The system accomplishes distributed software prototyping with legacy module reuse. Prototype System Description Language (PSDL), the prototyping language, is used to describe real-time software in the DCAPS system. PSDL specifies not only realtime constraints, but also the connection and interaction among software c...

Integrating heterogeneous components to form a distributed system can manifest difficult interoperability problems among the components. Contributing to this problem is a lack of understanding of the underlying software architecture of the components, and, possibly, the distributed architecture in which they participate. Middleware to resolve these problems may be difficult to choose and implem...

UML and MSC are widely used by software practitioners. SDL is an ITU standard language for telecommunications software specification. It has a formal semantics, and is supported by several commercial tools, which allow for simulation and validation of SDL design specifications as well as automatic code generation from these specifications. In order to take advantages of the SDL available tools ...

A distributed fault tolerant system for real time process control based on an enhancement of the distributed recovery block is described. Coverage is provided for failures in hardware, system software, networks, and application software. Fault tolerance provisions are introduced at the system level and in application software using an architecture based on the distributed recovery block (DRB). ...
