Nowadays, the wireless access network infrastructure is growing at an accelerated pace. In the current environment, which consists of a multitude of wireless networks, live migration of multimedia streaming between different type of connectivity offers important advantages for mobile users. In this paper we provide the description of an efficient mobility service architecture for multimedia environments. The proposed architecture handles multimedia streaming adaptation, session management and takes into consideration user profiles and a set of quality of service criteria. Session management in a mobile environment also implies that a handover mechanism must be used in order to ensure session continuity when a user moves from one network to another. Our architecture supports handover at the application layer which offers a better quality control than the majority of mobility solutions. In order to demonstrate the performance of our mobility solution, we analyze results from different test scenarios.

In this paper, we propose a theoretical framework (conceptualization and formalization) which seeks to model obesity as a process of transformation of one's own body determined by individual (physical and psychological), inter-individual (relational, i.e., relative to the relationship between the individual and others) and socio-cultural (environmental, i.e., relative to the relationship between the individual and his milieu) factors. Individual and inter-individual factors are tied to each other in a socio-cultural context whose impact is notably related to the visibility of any body being exposed on the public stage in a non-contingent way. The question we are dealing with in this article is whether such kind of social diseases, i.e., depending upon socio-environmental exposure, can be considered as "contagious". In other words, can obesity be propagated from individuals to individuals or from environmental sources over a whole population?

Nowadays we encounter an increasing need for electronic services that spans all over the services' taxonomy. E-services ease access to processes and resources that have implied a lot of administrative burden in the past. One of the most bureaucratic and conservative service areas is the administrative field. Our paper focuses on the solutions that we have developed in order to achieve the interoperability goals for pan-European administrative services based on existing PSCs (Point of Single Contact) developed in each EU country. The solution is based on a common specification that defines a layer that integrates the European administrative services on top of the functionality of the existing PSCs. The paper focuses the document model, a issue that determines the interoperability degree of the system.

With the increased focus on optimizing procurement processes, different procurement concepts have been developed. However, for these concepts no widely accepted best practice solutions exist. Furthermore, customers often impose specific conditions on suppliers. Thus implementations of these concepts are always different. Consequently suppliers cannot provide standardized services (e.g. Vendor Managed Inventory (VMI), Just-in-time or Just-in-sequence) to their customers, but have to be able to flexibly adapt these services to additional requirements. To address this, we developed an adaptable framework that includes all basic processes of these different procurement concepts, but furthermore being usable for individual distinctions. Therefore the supplier can provide services in a very flexible way by constructing them from the basic process steps. If these steps are supported by information and communications technology (ICT), further implementation decisions have to be made. To enable suppliers and customers to create an integrated model that reflects the process as well as the ICT level, we developed a business process modeling approach.

As mobile devices has become widely used, there is also an increasing economic interest in frameworks for service and product payment directly from mobile devices. Such a framework involves software applications running on the device itself. More importantly, the framework involves a flexible back-end in order to cover the wide range of possible transactions. The back end solution proposed in this paper consists in a generalized transaction engine which operates on abstract operations. The construction of the engine involves in the first stage the identification of the possible actors and operations which the system must support and in the second stage the formalization of a possible architecture for the engine itself.

Nowadays, Telecom service providers work in highly varied environment that includes cable television operators, Internet/Web-2.0 suppliers, and mobile/wireless services providers. Besides, end-user service personalization and short time-to-market are crucial characteristics to succeed. Thus, the main challenge for service providers is the implementation of a technical infrastructure that makes the information system simpler, more flexible, and open, while providing secure and reliable access to enterprise resources. Thus, we perform in this paper an analysis of capacities and requirements of a new platform, considering existing service providers' enterprise network architecture and future growth. Further, we (i) analyze the evolution of approaches and strategies in the Telco&IT landscape, also (ii) we categorize the requirements to service platforms and create an appropriate taxonomy. Finally, we examine the key features of a new architectural design based upon the concepts and components of the platform.

Product recommendation on electronic commerce Web sites becomes more important with the widespread use of Internet-based shopping. Collaborative filtering and content based filtering methods have been commonly used for this task by electronic commerce Web sites. These methods have several shortcomings, such as cold start problem, biased ratings problem or inaccurate recommendations. In order to produce effective and accurate recommendations, recent approaches utilize the semantic properties of data by integrating the domain ontology into the recommendation process. In these studies, the domain ontology covering only the types and properties of the product to be recommended is considered where the relational nature of the product data is omitted. However, the domain ontology of the features related to the product may also provide useful information during recommendation process. In this study, we focus on integrating the domain ontology of relational data into the recommendation process. We design a framework for an easy implementation of a recommendation system on relational data. Using this framework, we implement as a case study a recommendation model that recommends books to the users. We evaluated the performance of our model on real data obtained from a Turkish Internet book store. Our experimental results show that our proposed method can be effectively used for recommending items in relational data.

Proportional fairness has been shown to maximize the aggregate utility of rate control for elastic traffic in a resource sharing communication network, and has been applied to a broad range of resource allocation problems. For a refined analysis, however, the representation of proportional fairness as a relation between vectors with positive components will often not provide the level of detail that is needed. Therefore, we study the representation as a fuzzy relation, and propose several ways to specify a measure function to allocate a degree of (proportional) relatedness. The approaches are based on combinatorial aspects, especially size and number of related sub vectors, and geometric aspects, especially the minimum effort to change a vector to become related. A case study demonstrates that the introduced fuzzy fairness relations can be used to numerically evaluate the suitability of the maxmin fair state to represent the proportional fair state in a resource sharing network problem with maximum link capacities.
