The ability to deal with the requirements and preferences of mesh clients and their applications is still left aside in the recent trends for Wireless Mesh Networks (WMNs). In this paper, we split a WMN into a multitude of logical networks through virtualization, each one appropriate to specific levels of context features, e.g., security and cost preferences, mobility, and applications' requirements...
This panel seeks to initiate a discussion within the modeling and simulation community about the way we teach conceptual modeling for simulation with the view of bringing about improvements. The challenge addressed is how to educate and equip the novice analyst to become a professional rather than letting him become an artist - being very much the current practice. The need for professionalism is...
Mobile context modeling is a process of recognizing and reasoning about contexts and situations in a mobile environment, which is critical for the success of context-aware mobile services. While there are prior work on mobile context modeling, the use of unsupervised learning techniques for mobile context modeling is still under-explored. Indeed, unsupervised techniques have the ability to learn personalized...
The high quality of relationship of business to business (B2B) can reduce risks and trade costs and attain double-win of each other. In B2B context, the customers of certification industry are taken as investigation object, the service quality's impacts on relationship quality is explored in this paper. On the basis of existing researches, four dimensions(process service capability, process interactive...
Ad hoc network is an essential means of communication in disaster scenes. Validation of new communication protocols for these networks requires exhaustive simulation runs because real life experiences can be performed exclusively during expensive civil protection exercises. The necessity of these simulations calls for realistic and reliable mobility models which take into account numerous aspects...
Software services, in the near future, will be deployed on mobile, resource-limited devices that communicate through heterogeneous B3G (Beyond 3rd Generation) networks. They shall adapt themselves according to context and requirement changes without degrading software-related QoS. Supporting the development and maintenance of such services involves languages, methods and tools: this is the main target...
Conversational Recommender Systems (CRSs) are intelligent E-commerce applications that engage online users in an interactive conversation, until their interaction goal is achieved. To this end, traditional CRSs employ a recommendation strategy that is pre-determined by the system designers and followed rigidly during the recommendation session. In a previous paper, we have introduced a new type of...
During the past decade, engineering moved into virtual spaces in the leading industries and product model became a medium between communicating engineers. This change motivated the authors of this paper to make a development on currently prevailing product representations where human intent, engineering objective are not included in product models. Lack of this decision background information makes...
Knowledge work in modern organizations is increasingly performed collaboratively by distributed teams. Such collaboration involves dynamically changing situations. Making the collaboration environment fit the needs of these situations is supported by system-initiated adaptation based on the user and team context. Adaptation in the collaboration environment may confuse the users, because they cannot...
This paper introduces a new modeling method for improved engineering processes in product modeling. The proposed modeling is intended to be implemented in current product lifecycle management (PLM) systems. It is relied upon the information content based product modeling as proposed earlier by the authors. In this modeling, human intent based engineering objective and contextual connection definitions...
Applications running on mobile devices are intensely context-aware and adaptive. Streams of context values continuously drive these applications, making them very powerful but, at the same time, susceptible to undesired configurations. Such configurations are not easily exposed by existing validation techniques, thereby leading to new analysis and testing challenges. In this paper, we address some...
Symbiotic simulation is a paradigm in which a simulation system and a physical system are closely associated with each other. This close relationship can be mutually beneficial. The simulation system benefits from real-time measurements about the physical system which are provided by corresponding sensors. The physical system, on the other side, may benefit from the effects of decisions made by the...
Process acquirement which is the core task of requirement elicitation, lays the foundation for the process modeling. This paper gives the formal description of business processes; additionally the formalized expression of the activity-related products in the C4ISR architecture framework is also given, from which, the elements required by business processes can be acquired. The approach of business...
Engineering requires vast amount of highly related information about products, production environments, application environments, etc. at development, production, application, and recycling of products in advanced computer systems. During lifecycle of product, engineers and other humans have influence on product information according to their role within a project team or outside of it. Short innovation...
Pervasive computing requires that devices must be context-aware in order to provide proactively adapted services to both user and applications according to the current context. Most of the proposed approaches of service adaptation in a pervasive computing system are either not context-aware or based on an inappropriate definition of context. In this paper we propose a context-aware dynamic service...
A model of a knowledge intensive service system is introduced to study knowledge sharing in these systems. Simulation experiments based on the model are conducted to relate particular aspects of knowledge creation and sharing to a metric of service performance. The results indicate that certain network configurations of knowledge sharing among the service provider agents have performance advantages...
Context is a significant factor in deciding the set of requirements relevant to a system (i.e., software product construction), the alternatives the system can adopt to satisfy these requirements, and the quality assessment of each alternative. By context we mean the conditions in the operating environment of an system that influences how the system should behave in different situations. However,...
The general concept of separation of concerns (SoCs) aims at reducing the complexity of systems by identifying and encapsulating different system properties into separate coherent modules. Aspect-oriented software development (AOSD) applies the notion of SOC to effectively deal with crosscutting concerns that may induce high complexity when implementing and evolving software systems. However, for...
Ontology mapping is a key technology to resolve interoperability between heterogeneous and distributed ontologies. So far, many efforts have been conducted to suggest ontology mapping model. The RFCA mapping model is one of them. In this paper, the problem of the reduction of formal context in the mapping process of the RFCA model is addressed, and a method using Attribute Reduction to enhance the...
