Specification of software architecture reconfiguration

In the past years, Software Architecture has attracted increased attention by academia and industry as the unifying concept to structure the design of complex systems. One particular research area deals with the possibility of reconfiguring architectures to adapt the systems they describe to new requirements. Reconfiguration amounts to adding and removing components and connections, and may have to occur without stopping the execution of the system being reconfigured. This work contributes to the formal description of such a process. Taking as a premise that a single formalism hardly ever satisfies all requirements in every situation, we present three approaches, each one with its own assumptions about the systems it can be applied to and with different advantages and disadvantages. Each approach is based on work of other researchers and has the aesthetic concern of changing as little as possible the original formalism, keeping its spirit. The first approach shows how a given reconfiguration can be specified in the same manner as the system it is applied to and in a way to be efficiently executed. The second approach explores the Chemical Abstract Machine, a formalism for rewriting multisets of terms, to describe architectures, computations, and reconfigurations in a uniform way. The last approach uses a UNITY-like parallel programming design language to describe computations, represents architectures by diagrams in the sense of Category Theory, and specifies reconfigurations by graph transformation rules.

A high level e-maintenance architecture to support on-site teams

Emergent architectures and paradigms targeting reconfigurable manufacturing systems increasingly rely on intelligent modules to maximize the robustness and responsiveness of modern installations. Although intelligent behaviour significantly minimizes the occurrence of faults and breakdowns it does not exclude them nor can prevent equipment���s normal wear. Adequate maintenance is fundamental to extend equipments��� life cycle. It is of major importance the ability of each intelligent device to take an active role in maintenance support. Further this paradigm shift towards ���embedded intelligence���, supported by cross platform technologies, induces relevant organizational and functional changes on local maintenance teams. On the one hand, the possibility of outsourcing maintenance activities, with the warranty of a timely response, through the use of pervasive networking technologies and, on the other hand, the optimization of local maintenance staff are some examples of how IT is changing the scenario in maintenance. The concept of e-maintenance is, in this context, emerging as a new discipline with defined socio-economic challenges. This paper proposes a high level maintenance architecture supporting maintenance teams��� management and offering contextualized operational support. All the functionalities hosted by the architecture are offered to the remaining system as network services. Any intelligent module, implementing the services��� interface, can report diagnostic, prognostic and maintenance recommendations that enable the core of the platform to decide on the best course of action.

Conference on Enabling Teachers for Entrepreneurship Education

The Conference on Enabling Teachers for Entrepreneurship Education (ENTENP2013) in Initial Teacher Education (ITE) will be held at the Guarda Polytechnic Institute (GPI) in Guarda on 7/8 June 2013. We expect delegates from all the Portuguese Higher Education Institutions and the EU Member States, as well as Pre-Accession Countries and countries participating in the Competitiveness and Innovation Framework Programme (CIP). ENTENP 2013 addresses to all practitioners from the area of teacher education and entrepreneurship education, but also the early stage adopters of education in entrepreneurship. The conference is jointly organized by Guarda Polytechnic Institute with the collaboration of Castelo Branco Polytechnic Institute, Viana do Castelo Polytechnic Institute and Universidade Nova de Lisboa and shall be hosted by the European Commission and GPI. The purpose of the event is to discuss burning questions and exchange good practice examples in the field of enabling teachers for entrepreneurship education and looking at possible areas of development and cooperation.
