Estudio comparativo de las herramientas MetaCASE bajo consistencia y refinamiento*
Las herramientas MetaCASE surgieron como una evolución de la tecnología CASE, para superar algunas de las limitaciones identificables en este tipo de tecnologías. Estas herramientas poseen mecanismos que permiten la creación y modificación de paradigmas de metamodelamiento, además de la adición de restricciones que se pueden emplear en chequeos de consistencia o transformaciones de refinamiento. En el artículo que aquí se presenta, se realiza un estudio comparativo de cinco herramientas MetaCASE (AToM3, DOME, GME, MetaEdit+ y UN-MetaCASE), tomando en cuenta dos puntos de vista: características generales y capacidades para la realización de chequeos de consistencia y transformaciones de refinamiento. El artículo concluye con un análisis comparativo de dichas herramientas

Capturing the Data Uncertainty Change in the Cocaine Consumption in Spain Using an Epidemiologically Based Model
A probabilistic model is proposed to study the transmission dynamics of the cocaine consumption in Spain during the period of 1995-2011. Using the so-called probabilistic fitting technique, we study if the model is able to capture the data uncertainty coming from surveys. The proposed model is formulated through a nonlinear system of difference equations whose coefficients are treated as stochastic processes. A discussion regarding the usefulness and limitations of probabilistic fitting technique in order to capture the data uncertainty of the proposed model is presented
Estudio comparativo de las herramientas MetaCASE bajo consistencia y refinamiento*
MetaCASE tools have emerged as an evolution of CASE technology, for the overcoming of limitations identified in CASE tools. MetaCASE tools have mechanisms for both creation and modification of metamodeling paradigms, in addition to constraints addition—useful in consistency checking or refinement transformations. In this paper, there was a comparative study done on five MetaCASE tools (AToM3, DOME, GME, MetaEdit+ and UN-MetaCASE), from two points of view: general features and capabilities for consistency checking and refinement transformations. We conclude with some comparative analysis of these tools.Las herramientas MetaCASE surgieron como una evolución de la tecnología CASE, para superar algunas de las limitaciones identificables en este tipo de tecnologías.

Procesado masivo y automático de trazas en redes celulares
The introduction of new services in mobile communications usually requires extensive evaluation campaigns. Even though new services and devices may have undergone conformance testing, it is important to ensure they do properly work in real live networks, where some parameters, signalling procedures or timer values may differ from those used in conformance testing. It is also important to diagnose error sources. This paper describes a tool that automatically analyses traces captured by the mobile terminal. Its design addresses two main challenges: the efficient handling of the large amount of information captured by the terminal and the extraction of relevant information from traces generated by different sources.Universidad de Málaga.

An experimental test of how parasites of predators can influence trophic cascades and ecosystem functioning
AbstractParasites can shape the structure and function of ecosystems by influencing both the density and traits of their hosts. Such changes in ecosystems are particularly likely when the host is a predator that mediates the dynamics of trophic cascades. Here, we experimentally tested how parasite load of a small predatory fish, the threespine stickleback, can affect the occurrence and strength of trophic cascades and ecosystem functioning. In a factorial mesocosm experiment, we manipulated the density of stickleback (low vs. high), and the level of parasite load (natural vs. reduced). In addition, we used two stickleback populations from different lineages: an eastern European lineage with a more pelagic phenotype (Lake Constance) and a western European lineage with a more benthic phenotype (Lake Geneva). We found that stickleback caused trophic cascades in the pelagic but not the benthic food chain. Evidence for pelagic trophic cascades was stronger in treatments where parasite load of stickleback was reduced with an antihelmintic medication, and where fish originated from Lake Constance (i.e., the more pelagic lineage). A structural equation model revealed that differences in stickleback lineage and parasite load were most likely to impact trophic cascades via changes in the composition, rather than overall biomass, of zooplankton communities. Overall, our results provide experimental evidence that parasites of predators can influence the cascading effects of fish on lower trophic levels with consequences on ecosystem functioning.</jats:p
