In this paper, we propose to design a mobile agent execution environment, based on the bare coordination media. To do this, we discuss two ways to enhance a coordination medium. First, we introduce a way to add system specific non-functional behaviour (such as performance, security) to the medium, in order to add dynamism to the otherwise fixed coordination laws. Our current research focuses on...

Workflows (Wfs) are a major enabling technology for ecommerce. In our research, a Combined Negotiation (CN) is modeled and enacted using Wf technology. The modeling task captures the sequencing of the individual negotiations as well as the dependencies between them, and the enacting task runs the model. A CN support system (CONSENSUS) is used by the user to perform both tasks. Supporting dynami...

Care pathways are excellent tools for the standardization of care delivery and the improvement of clinical efficiency. The high dynamism and unpredictability of the clinical environment require pathways to be adaptable to the deviations that may arise during their execution. In this work we present a methodology for the identification, monitoring, detection and managing of these deviations. Suc...

In exploring the evolution of Iranian architecture from prototypes to the present day, Qajar architecture is an important part of Iranian architecture history. The importance of this era's architecture is because large changes in conceptual and physical context occurred slowly in Iranian architecture during this time. These changes, especially from the Nasserian period (the second Qajar era), h...

The flexibility and dynamism of ubiquitous computing systems have a strong impact on the way their security can be achieved, reaching beyond traditional security paradigms like perimeter security and communication channel protection. Constant change of both the system and its environment demand adaptive security architectures, capable of reacting to events, evaluating threat exposure, and takin...

The current paper presents a semi-automated method for evaluating SOAs called SOAQE. This method corrects defects observed so far such as lacks of pertinence and accuracy for evaluation results. SOAQE takes as a starting point the McCall model, describing software quality, which led to an international standard for the evaluation of software quality (ISO 9126). This model is organized around th...

Networks of the future will be characterized by a variety of computational devices that display a level of dynamism not seen in traditional wired networks. Because of the dynamic nature of these networks, resource discovery is one of the fundamental problems that must be solved. While resource discovery systems are not a novel concept, securing these systems in an efficient and scalable way is ...

In this paper the orchestration of wearable sensors with human computation is explored to provide map metadata for blind navigation. Technological navigation aids for blind must provide accurate information about the environment and select the best path to reach a chosen destination. Urban barriers represent dangers for the blind users. The dynamism of smart cities promotes a constant change of...

We consider a team of agents that are required to coordinate their actions in order to maximize a global objective. Our domains are characterized by uncertainty, dynamism, and distributed information. Determining appropriate actions becomes quite difficult, especially as the number of agents and the coupling between them increases. This paper discusses five contributions toward the goal of coor...

In the present economy, business-to-business (B2B) relationships are usually long-termed and characterised by a high degree of mutual preexisting trust. With the advent of the Internet economy, E-Services marketplaces will provide an infrastructure where B2B relationships will be set up in a highly dynamic fashion. The increased dynamism of the marketplace introduces issues of lack of trust amo...
