Self-adaptive component-based architectures facilitate the building of systems capable of dynamically adapting to varying execution context. Such a dynamic adaptation is particularly relevant in the domain of ubiquitous computing, where numerous and unexpected changes of the execution context prevail. In this paper, we introduce an extension of the MUSIC(More)
Chlorophyll, primary production, zooplankton biomass and the species composition of phytoplankton and zooplankton were studied in 2003, after the Prestige shipwreck. The information obtained was compared to previous data series available for the area affected by the spill. A large data series on plankton variables for the N-NW Spanish coast existed, and(More)
Context management in pervasive computing environments must reflect the specific characteristics of these environments, e.g. distribution, mobility, resource-constrained devices, or heterogeneity of context sources. Although a number of context models have been presented in the literature, none of them supports all of these requirements to a sufficient(More)
Today software is the main enabler of many of the appliances and devices omnipresent in our daily life and important for our well being and work satisfaction. It is expected that the software works as intended, and that the software always and everywhere provides us with the best possible utility. This paper discusses the motivation, technical approach, and(More)
With the continuous improvement of device capabilities, mobile applications are becoming not only context-aware, but also self-adaptive. This new trend of applications are capable of tuning their behavior depending on changes observed in the surrounding environment. However, these adaptations are often restrained by the static features of the supporting(More)
This paper proposes an architecture, based on statistical machine translation, for developing the text normalization module of a text to speech conversion system. The main target is to generate a language independent text normalization module, based on data and flexible enough to deal with all situations presented in this task. The proposed architecture is(More)
Seasonal variations in phytoplankton and bacterial biomass along with rates of primary production, dissolved organic carbon (DOC) release, bacterial production, dark respiration and vertical particle flux were determined from December 1998 to September 1999 at a coastal station off A Coruña (NW Spain) affected by episodes of wind-driven upwelling. Maximum(More)
Ball screens are one of the most frequently used tactical behaviour in elite basketball games. The aim of the present study was to identify their predictors of success related to time, space, players, and tasks performed. The sample was composed of 818 ball screens corresponding to 20 close games (mean differences in score of 3.1 ± 0.8 points) randomly(More)
