Abstract
Planning in education is a process that can determine the success of learning. This has major impact in engineering education, where students have to develop complex competences in order to make decisions that can influence the world and humankind. Teachers are reluctant regarding the effective practice of planning educational processes, identifying the lack of time and appropriate pedagogical training as main causes for the problem. Our aim is contribute to solve this problem. This paper presents the exploration of the capabilities of conceptualization of planning by the IMS-LD educational modelling language, through CADMOS authoring tool. To do so we used a learning object of a discipline of a Computer Engineering higher education course. Several specifications were made in CADMOS, based on different learning strategies common used in engineering education. The results show that IMS-LD and CADMOS can help and simplify the planning process for teachers, allowing them to implement changes, reuse and share planning products. Limitations were identified, but they do not preclude the use of the tool for planning.

Abstract
In this 21st century, Portugal faces substantial social challenges. The knowledge society requires citizens prepared and capable to face the challenge of a globalized and competitive economy, where the use and access of the technologies of information and communication assume a dominant position. The tasks of attending to the demands of this new model of social relationships have been showing the absence of a consolidated social answer. Despite the fact that Portugal has been showing indicators of significative increases of digital inclusion, a digital divide is still present. Thus, news literacies are required and new forms of illiteracy will consequently appear. Most countries in the European Union have been developing programs for strong networks of Public Libraries, as well as training people for accessing and using public information services. In Portugal only in the 80's was it possible to initiate the implementation of a net of Public Libraries with adequate infrastructures, what configures a serious delay for facing the defying situation described earlier. It is for that reason that is essential to understand and develop intervention strategies. This paper presents part of the results of a research project, supported by the Foundation for the Science and the Technology, which assess the level of informational skills of Portuguese students in the Higher and Secondary Education. The assessment, carried out in nine Portuguese cities, intends to evaluate the level of preparation presented by the students to face, not only the challenges of the information society, but also the incoming changes of a European Higher Education Area.

Abstract
ReFlO is a framework and interactive tool to record and systematize domain knowledge used by experts to derive complex pipe-and-filter (PnF) applications. Domain knowledge is encoded as transformations that alter PnF graphs by refinement (adding more details), flattening (removing modular boundaries), and optimization (substituting inefficient PnF graphs with more efficient ones). All three kinds of transformations arise in reverse-engineering legacy PnF applications. We present the conceptual foundation and tool capabilities of ReFlO, illustrate how parallel PnF applications are designed and generated, and howdomain-specific libraries of transformations are developed.

Abstract
A common problem in networking research and development is the duplicate effort of writing simulation and implementation code of network protocols. This duplication can be avoided through the use of fast prototyping development processes, which enable reusing simulation code in real prototyping and in production environments. Although this functionality is already available by using ns-3 emulation, there are still limitations regarding the additional packet processing that emulation introduces, which degrades the node’s performance and limits the amount of network traffic that can be processed. In this paper we propose an approach to reduce the performance problem associated with fast prototyping that consists in migrating data plane operations processing to outside of ns-3. In a well-designed network, most of the traffic should be data. By moving the data plane operations outside of ns-3 the overhead associated with this kind of traffic is greatly reduced, while control plane protocols may still be reused. In order to validate our proposed solution, we extended the Wireless Metropolitan Routing Protocol (WMRP) and Optimized Link State Routing (OLSR) protocols to use the developed architecture, tested their performance in real environments, and verified the amount of code reuse between the simulator and the real system.

Abstract
In this paper, we analyse the impact of spring temperature (ST) and soil water (SW) on wine production volume (WPV) for the period 1933 to 2013 in the Douro region. We employ a state-space regression model to capture possible structural changes in wine production caused by a change in ST and/or SW. We find that the ST explains about 65 % of the variability of WPV. In contrast, the summer SW level increases the R (adj)-square to 83 % and the Akaike criterion value was lower. We also find interesting dynamic properties of SW and ST. The immediate impact of an increase in SW is negative for WPV, while the SW that is in the ground, i.e. from the previous 2 and 3 years, have a positive effect on actual WPV. Moreover, the individual changes of ST and SW have similar dynamic impact on WPV. Our main finding is that climate change does not only change the variables in question but also the winegrape vineyards adding to the negative impact on WPV levels. As a result we observe a shift of the relative importance away from ST to SW.
