The restructuring of the electricity industry has spawned the introduction of new independent grid operators (IGOs), typically called transmission system operators (TSOs); independent system operator (ISOs); or regional transmission organizations (RTOs), in various parts of the world. An important task of an IGO is congestion management (CM) and pricing.(More)
Although architecture-based self-adaptation has been widely used, there is still little understanding about the validity and tradeoffs of incorporating it into real-world software-intensive systems which already feature built-in adaptation mechanisms. In this paper, we report on our experience in integrating Rainbow, a platform for architecture-based(More)

This deliverable details the application scenarios for which DVC may bring major benefits, highlighting the expected advantages for each scenario. In particular, the functionalities usually identified in the literature as DVC strengths, such as error resilience, encoder-decoder complexity tradeoff, low-power encoder consumption, but also coding efficiency(More)
Architecture-based self-adaptation is considered as a promising approach to drive down the development and operation costs of complex software systems operating in ever changing environments. However, there is still a lack of evidence supporting the arguments for the beneficial impact of architecture-based self-adaptation on resilience with respect to other(More)
This paper describes the design and implementation of a system for managing the tagging of traffic, in order to create detailed personal and applicational profiles. The ultimate goal of this separation is to facilitate the task of traffic auditing tools, namely in their struggle against botnets. The architecture was designed for domestic or enterprise(More)
Complex software-intensive systems are increasingly relied upon for all kinds of activities in society, leading to the requirement that these systems should be resilient to changes that may occur to the system, its environment, or its goals. Traditionally, resilience has been achieved either through: (i) low-level mechanisms embedded in the implementation(More)
Editor's Note:In this issue, we feature a range of applications with potential to impact our everyday lives. The first two reports are related to this issue's theme, proposing sensor-based systems for energy management and eldercare. Also featured are three automotive computing proposals, which offer solutions for activity promotion, path prediction, and(More)
Crystalline 1:1 inclusion complexes with beta-cyclodextrin (beta-CD) and the sodium salt of nimesulide (4-nitro-2-phenoxymethanesulfonanilide), and the sodium salt of the derivative 2-phenoxymethanesulfonanilide, have been prepared by co-precipitation from aqueous solution. The presence of true inclusion complexes was supported by elemental analysis,(More)
This paper holds as its core objective the report of the research developed towards the conceptualisation and prototyping of an Information Visualisation system capable of providing a quick and accurate view of the set of data collected by the SAPO Broker web service regarding access activity in the SAPO news website. SAPO Broker, a real-time monitoring(More)
