We present, for the first time to our knowledge, results on the characterization of response of a dual resonance observed in the spectrum of a single long-period grating arcinduced in a B/Ge co-doped fiber to different physical parameters. The dual resonance is formed by two overlapping resonances corresponding to coupling of the core mode to symmetric and antisymmetric cladding modes. Therefore, these resonances may behave differently when strain, bending, torsion, or temperature is applied to the grating. We show that the bending, strain, and torsion sensitivities of the two resonances are very different, while the temperature sensitivities are almost the same. © 2008 IEEE.

Abstract
The European Space Agency (ESA) has created the Simulation Model Portability 2 (SMP2) standard with the purpose to provide a design solution for the project of Spacecraft Simulators. One element of the SMP2 standard is the metamodel Simulation Model Definition Language (SMDL). The design artefacts of a Spacecraft Simulator consist in descriptions of the business logic shared by a set of SMP2 models. This paper reports results from a study that considers the hypothesis to complement the model-driven design approach of the SMP2 standard with test-driven design techniques. The high-level abstractions of Spacecraft Simulators are used to carry out Model-Driven Development processes, while reusable pieces of software that can to be used by many SMP2 models are designed and developed following Test-Driven-Development. The tool capable to establish the dependencies between the source code produced by the two methodologies and mission specific source code is the GNU Build System.

Abstract
The internet in the last few years has changed the way people interact with each other. In the past, users were just passive actors, consuming the information available on the web. Nowadays, their behavior is the opposite. With the so-called web 2.0, internet users became active agents and are now responsible for the creation of the content in web sites like MySpace, Wikipedia, YouTube, Yahoo! Answers and many more. Likewise, the way people buy a product or service has changed considerably. Thousands of online communities have been created on the internet, where users can share opinions and ideas about an electronic device, a medical service or a restaurant. An increasing number of consumers use this kind of online communities as information source before buying a product or service. This article describes a web system with the goal of creating an online community, where users could share their knowledge about local services, writing reviews and answering questions made by other members of the community regarding those services. The system will provide means for synchronous and asynchronous communication between users so that they can share their knowledge more easily.

Abstract
The education of professional engineers has been mainly oriented towards the requirements of industry, although many graduates will start and end up working in service organizations. Services always involve interaction, either directly between people or using machines. Most services now require the use of technology, including self service machines, Internet and mobile equipments and may involve complex social and organizational issues. Although engineering programs have evolved in order to accommodate changes in the economy, new proposals must be taken into new graduate and postgraduate education. This paper proposes MESG1, a Master program in Services Engineering and Management compatible with the Bologna European framework. It is still a program to educate professional engineers, in the sense that graduates will be prepared to Conceive, Design, Implement and Operate (CDIO) complex value-added engineering systems. But MESG has a strong emphasis on: (i) understanding the innovative technologies now required for service provision, (ii) understanding the functional and the experience requirements of people using services, and (iii) management of the service CDIO process and understanding its value. Knowledge and experience about people and about business, in social-organizational environments, are important components in the advanced education of service engineers and managers.
