For the purpose of high reliability and low cost when distributed computing system is developed, an architecture description language based on software reliability evaluation for distributed computing systems (REAL) is proposed in this paper. Its main purpose is used to describe the software architecture of distributed computing system in order to evaluation reliability of a given architecture. It...
This paper applies Grid Computing techniques to 3D CAD system selection and collaborations. The paper first proposes a software architecture based on Grid Computing,then describes the data structures and XML based methods to describe 3D CAD grid resources. Next, it presents a solution to share data between different 3D CAD systems, and a Globus based software prototype implementation is given.
Cloud/Grid environments are characterized by a diverse set of technologies used for communication, execution and management. Service Providers, in this context, need to be equipped with an automated process in order to optimize service provisioning through advanced performance prediction methods. Furthermore, existing software solutions such as GNU Octave offer a wide range of possibilities for implementing...
Nowadays, we are in the information society in which it is important to exchange knowledge that supports the research process; on the other hand, it is evident the multilingualism limitations that established in these processes. This fact makes us think and makes us see the need to create mechanisms to include everyone in the global context; in this paper is presented the current status about research...
The establishment of IT-supported processes within organizations requires the integration of existing distributed legacy applications. Therefore, Web services can be generated as wrappers to flexibly integrate existing distributed legacy applications using a standardized interface. Existing approaches mostly focus on the technical issues of the integration using Web services and do not support the...
A global information model (GIM) is to describe all the engineering information across a service-oriented system design. GIM includes both business and design information of the systems. Business information is the involved services, service providers, service requestors, business objects, and business processes. Design information is the relationships and rules in developing service-oriented systems...
Service technology proposes a loosely-coupled integration and composition of any service functionalities, exposed by XML-based interfaces and composed using standards such as BPEL. Nevertheless, as cross-organizations are swiftly competing, the rigid character as well as the ad-hoc deployment using these standards is still hindering the large-scale application of this service paradigm. This contribution...
Our approaches forth the UML's behavior model as a premise, because defined events of an object in a sequence diagram orderly mean user scenarios with functional requirements, which can be managed for later engineered works. Therefore, we'll construct the meta architecture for a mathematical basis with various levels of abstraction in requirements, and then propose the process model that defines the...
This article proposes a model of car-to-car networks based on an adaptive self-organization overlay network. Car-to-car network is one of the promising ways to deliver the information and services among cars in order to increase the safety and reduce the traffic congestion. However, conventional works focus on the low-level communication protocols. Little works are done on the model and its nature...
Over the last decade, a large number of Method Engineering (ME) approaches have been developed to adapt information system methods (ISM) to specific situations of projects at hand. However, ME has not been yet, widely spread in the professional world. Our belief is that limitations such as the lack of standards, the proposal of proprietary solutions and an excessive emphasis on engineering issues...
ADAPT is a tool that aims at easing the task of evaluating dependability measures in the context of modern model driven engineering processes based on AADL (Architecture Analysis and Design Language). Hence, its input is an AADL architectural model annotated with dependability-related information. Its output is a dependability evaluation model in the form of a Generalized Stochastic Petri Net (GSPN)...
Systems verification requires first to model the system to be verified, then to formalize the properties to be satisfied, and finally to describe the behaviour of the environment. This last point, known as the proof context, is often neglected. It could, however, be of great importance in order to reduce the complexity of the proof. The question is then how to formalize such a proof context. This...
Groupware systems are closely related with factors which define organization and knowledge of the group. Taking into account these factors are very variable, development and management processes of these systems are complex and need adaptable infrastructure which guarantees their correct evolution. From this need, we propose AGORA as a layered architecture for building flexible cooperative applications...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
Current fashion systems to interconnect large software architectures are moving toward SOA based solutions. This new paradigm for designing system can be improved, in our opinion, by using semantics. Semantics can a play a main role in boosting interoperability thanks to current technologies to express knowledge and to describe semantic Web services (SWS). This paper tackles the provision of a Software...
