Abstract
The 2001/77/CE Renewable Energies European Directive together with Kyoto Protocol ratification supported by a government vision and strong objective on the reduction of external oil dependence put Portugal in the front line to achieve one of the highest wind energy penetrations within 10 years' time. This paper gives a summarized overview of the Portuguese technical approaches and methodologies followed in order to plan and accommodate the ambitious wind power goals to 2010/2013, preserving the overall quality of the power system.

Abstract
Due to data-driven application nature and its increasing complexity, developing its user interface can be a repetitive and time-consuming activity. Consequently, developers tend to focus more on the user interface aspects and less on business related code. In this paper, we're presenting an alternative approach to graphical user interface development for data-driven applications, that allows developers to refocus on the source code and concentrate their efforts on application core logic. The key concept behind our approach is the generation of concrete graphical user interface from a source code based model, which includes the original source code metadata and non-intrusive declarative language extensions that describes the user inter-face structure. Concrete user interface implementation will be delegated to specialized software packages, developed by external entities, that provides complete graphical user interfaces services to the application. When applying our approach, we're expecting faster graphical user interface development.

Abstract
The engineering of ubiquitous computing systems provides important challenges. Not least among these is the need to understand how to implement designs that create a required experience for users. The paper explores a particular class of such systems for built environments. In particular it is concerned with the capture of experience requirements and production of prototypes that create experience. The aim is to develop methods and tools for such environments to enable the creation of particular sorts of experience in users. An approach that combines the use of scenarios, personae and snapshots with the use of prototypes and models is described. The technique aims to elicit an understanding of the required experience of the system and then create a design that satisfies the requirements. © 2008 Springer Berlin Heidelberg.

Abstract
This paper presents an automatic system to extract and classify DNA profiles in a digital image. The system uses image segmentation and cumulative histogram analysis to identify both the number of layers in the image, and the number of profiles present in each layer. Once the individual profiles are located, their signatures are extracted and used to perform a hierarchical classification of the individual DNA profiles.

Abstract
This paper is part of a long-term effort to introduce precision viticulture in the region of Demarcated Region of Douro. It presents the architecture, hardware and software of a platform designed for that purpose, called MPWiNodeZ. A major feature of this platform is its power-management subsystem, able to recharge batteries with energy harvested from the surrounding environment from up to three sources. It allows the system to sustain operation as a general-purpose wireless acquisition device for remote sensing in large coverage areas, where the power to run the devices is always a concern. The MPWiNodeZ, as a ZigBee (TM) network element, provides a mesh-type array of acquisition devices ready for deployment in vineyards. In addition to describing the overall architecture, hardware and software of the monitoring system, the paper also reports on the performance of the module in the field, emphasising the energy issues, crucial to obtain self-sustained operation. The testing was done in two stages: the first in the laboratory, to validate the power management and networking solutions under particularly severe conditions, the second stage in a vineyard. The measurements about the behaviour of the system confirm that the hardware and software solutions proposed do indeed lead to good performance. The platform is currently being used as a simple and compact yet powerful building block for generic remote sensing applications, with characteristics that are well suited to precision viticulture in the DRD region. It is planned to be used as a network of wireless sensors on the canopy of vines, to assist in the development of grapevine powdery mildew prediction models.

Abstract
Electronic commerce is currently a world-wide phenomenon, with multiple impacts on the success and evolution of organizations of various business areas, due to its unique features that both challenge and revolutionize traditional entrepreneurial reasoning. However many enterprises have experienced difficulties with their e-commerce initiatives, either due to lack of information, or because of the innumerable difficulties found in the definition of an action plan. Recognizing the importance of a broad and deep understanding of the multiple aspects supporting and constraining e-commerce, a theoretical model that explains electronic commerce initiatives is proposed. The model was developed following a qualitative methodology known as Grounded Theory, whose purpose is to assist organizations in their e-commerce initiatives. The work led to the identification and description of factors that influence the adoption and exploitation of e-commerce in Portuguese organizations.
