Traditional software testing methods combined with probabilistic models cannot measure and assess dependability for software that requires very high reliability (failure rate < 10 /hour) and availability (>0.999999). This 6 paper proposes a novel approach, drawing on findings and methods that have been described individually but have never been combined, applied in the late testing phase or ear...

Management, be it multi-access, resource, mobility or network management, is a key aspect in the design, deployment and operation of current and future networks. The challenges that mobile network management faces today are increasingly associated with the multiplicity of operating environments. For instance, heterogeneous resource sharing, dealing with a larger variety of user profiles, and op...

Mass Customization may be deployed in many different fashions depends on the nature of product characteristics, market segments, and their respective business environments. General trend shifts from personalize crafted, mass produced, to mass customized products throughout recent decades have evolved to unequal influences on today’s customizable product configurations. Life cycle durations and ...

The Web services paradigm offers numerous potential benefits to the health care area. These include interoperability, portability, scalability, and compliance with universal standards. However, development of large-scale Web services applications in health care is relatively scarce. Multiple challenges are slowing the diffusion of information technology practices in health care, starting with t...

Information overload is a well documented problem in many application domains. A way of addressing this problem is by creating user profiles and by filtering out all irrelevant information while presenting the users only with information that matches their interests. Our focus is on the spatial domain. We follow an implicit profiling approach by logging users’ mouse movements as they interact w...

This report presents a novel game-theoretical framework to model the evolution of spectrum markets that consists of multiple spectrum/network operators that provide wireless access to users. It integrates models about the channel, mobility, user preference, network operators (providers), infrastructure deployment, user distribution, and price-adaptation mechanisms. Providers aim to maximize the...

Intermediaries are software entities, deployed on hosts of the wireline and wireless network, that mediate the interaction between clients and servers of the World Wide Web. In this paper we present a survey of intermediaries, focusing on systems beyond simple caching proxies. We classify different intermediary systems into three categories, based on their functionality and focus: First, we inv...

A UML profile for a system or an application is a standard means for expressing the semantics of this system or application using a set of predefined extensions to UML. UML profiles allow all stakeholders of a system to share a common graphical notation and vocabulary, and permit more precise specifications and better documentation on how to use and customize systems. In this paper we present a...
