Nowadays one can observe rapid development of various technologies supporting autonomic features and context-awareness of pervasive systems. And this is perfectly understandable as these features effectively increase the systems autonomicity. However, in the case of safety-critical realtime systems it becomes crucial to determine how the entire system performance is affected by the growth in complexity...
Several games nowadays try to improve the player immersion by representing human behavior as real as possible, generally using agent technologies to model non-player characters (NPCs). However, agent-based behavioral models representing the existing complexity of, for instance, a decision-making for a real life situation can become a very intensive computing task. For this reason, real-time simulation-based...
As services are dynamic discovered and bound in the open Internet environment, testing has to be exercised continuously and online to verify and validate the continuous changes and to ensure the quality of the integrated service-based system. During this process, testing strategies have to be adapted in accordance to the changes in the environment and target systems. Software agents are characterized...
The existing security defensive systems, which have limitations in many ways, can not adapt to the need of future network defense. In allusion to the problem, an intelligent security defensive software is designed. It has intelligent functions such as environment awareness, self-adaptation, dynamic reconstruction, and so on. Besides, the general realization methods are proposed herein.
This paper proposes an agent-based adaptive Architecture to extend Moodle in order to support instructional decisions and adaptive behaviour in engineering education. The paper describes the characteristics, functions, and interactions of the agents which take part in each module of the adaptive architecture. In addition, we describe the origin and function of ToDei, the proposed intelligent agent...
Architecture-centric system is the logical model about self-adaptive goal's achievement of software. Based on this concept, requirement service is the driven power, the strategy definition of self-learning and self-(decision-making) is viewed as inner evolution of architecture's business mechanism. Agent is the basic internetware granularity of architecture, it is to build an architecture-centric...
The modern sea combat is a typical complex adaptive system (CAS), involving a large number of subjective and qualitative factors, which is difficult to explore for many traditional methods. This paper adopts artificial life to establish a simulation system of modern anti-surface warfare of warship fleet to research the impact of the important subjective and qualitative factors on the warfare result...
This paper discusses architecture-centric concept. For its adaptive all-purpose demand, decision-making and belief mechanism of agent is put forward, whose logic relations will be built. According to self-adaptive agent network mechanism, fine-grained service and coarse-grained service defined specifically. By AA/TT engine's topology process, service clusters are selected and optimized as agent group,...
The construction industry has been facing a paradigm shift to (i) increase; productivity, efficiency, infrastructure value, quality and sustainability, (ii) reduce; lifecycle costs, lead times and duplications, via effective collaboration and communication of stakeholders in construction projects. Digital construction is a political initiative to address low productivity in the sector. This seeks...
Digital Earth (DE) is a virtual presentation of the planet based on geographic coordinate, and is an information system with tremendous amount of multiple resolutions and multiple scales data as shown in multiple dimensions. It can visualize the real earth and represent historical phenomena in digital way by using the large amount of data of the earth, and utilizing the computer techniques, image...
To develop more powerful and flexible Organizational Decision Support Systems (ODSS), after the introduction of abstract architecture of a federated MAS system with two types of agent, the architecture of AODSS with three layers has been presented. The core layer includes two kinds of agencies: Application Agency for the common applications of this system, and Decision Agency for performing the actual...
Information privacy is usually concerned with the confidentiality of personally identifiable information (PII), such as electronic medical records. Nowadays, Web services are used to support different applications which may contain PII, such as healthcare applications. Thus, the information access control mechanism for Web services must be embedded into privacy-enhancing technologies. Further as application...
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...
