English Abstract Generating and maintaining user access to resources like e-learning courses is a time and money consuming process for both, users and resource providers. In authentication and authorization infrastructures such as Shibboleth, PAPI and Liberty Alliance, home organizations authenticate their own users and provide a set of user information attributes to the resources they access, ...

Systems are becoming exceedingly complex to manage. As such, there is an increasing trend towards developing systems that are self-managing. Policy-based infrastructures have been used to provide a limited degree of automation, by associating actions to system-events. In the context of self-managing systems, the existing policy-specification model fails to capture the following: a) The impact o...

Positioned at the confluence between human/machine and hardware/software integration and backed by a solid proof of concept realized through several scenarios encompassing e-Securities, e-Health, and e-Logistics for global manufacturing and emergency response management, this work exploits latest advances in information and networking technologies to set a systematic framework for the design of...

The objective of this empirical study is to find ways that best support business performance through the alignment of organizational and technological infrastructures. Adapting Tapscott and Caston's infrastructure themes, the organizational infrastructure includes components such as common vision, cooperation, empowerment, adaptability and learning, and the technological infrastructure addresse...

and References AbstractThis paper analyzes the convergence of information technology infrastructures and traditionaleducational spaces and proposes flexible criteria for material-virtual, hybrid learning environments. Idevelop the concept of built pedagogy to account for the ways that built environments teach valuesthrough their constraints upon social action and interaction and...

Pervasive computing devices and communication infrastructures enable learning situations that occur in both the physical and the virtual world. However, deploying these pervasive situations is still a challenge for teachers. This paper presents GLUEPS-AR, a system for deploying learning designs across physical and web spaces, using mainstream Virtual Learning Environments, Web 2.0 artifacts and...

In this paper we propose an architecture of e-learning systems characterized by the use of Web Services and a suitable Middleware component. These technical infrastructures allow us to extend the system with new services as well as to integrate and reuse heterogeneous software e-learning components. Moreover, they let us better support the “anytime and anywhere” learning paradigm. �s a matter o...

Vehicular travel is increasing throughout the world, particularly in large urban areas. Therefore the need arises for simulating and optimizing traffic control algorithms to better accommodate this increasing demand. In this paper we study the simulation and optimization of traffic light controllers in a city and present an adaptive optimization algorithm based on reinforcement learning. We hav...
