Projecte realitzat en el marc d'un conveni entre l’empresa Unit4 i la UAB. Unit4 es dedica a oferir solucions ERP per la gestió global de les empreses i serveis associats. El concepte de distribució dins de l’empresa es tradueix al paquet d’objectes (taules, formularis, classes, etc...), que s’entreguen al client i que solen contenir o bé versions inicials o bé algunes actualitzacions de versions ja existents. Aquest sistema és utilitzat per tots els sectors de l’empresa i la seva realització actual és completament manual. El projecte es centrarà en realitzar un conjunt d’eines per facilitar les diferents tasques implicades en la generació de distribucions.

Herein we report an analysis of an Oxfordian (Upper Jurassic) paleoreef located in the Swiss Jura Mountains. The paleoreef is located in a Middle Oxfordian transitional interval in which sedimentation switched from marl-dominated to carbonate-dominated deposits. The paleoecosystem is composed of four successive fossil communities characterized by microsolenid corals and organisms that specialized in suspension feeding. Carbon isotopes measured from echinoid spine carbonates exhibit a positive trend from similar to 1.0 parts per thousand to 2.5 parts per thousand in delta(13)C values from the base to the top of the paleoreef. Comparison of delta(13)C curves with organic matter and belemnites shows different patterns not compatible with a global variation of the carbon cycle. Similar fossil assemblages and stratigraphic sequences identical in age are found along the continental margin of the Tethys-Atlantic Ocean. This biolithostratigraphic succession corresponds to increasing delta(13)C values of marine and biogenic carbonates, to the transition from marl-dominated to carbonate-dominated deposits, and to the development of carbonate platforms, which together suggest a change in the carbon cycling regime within the Tethys-Atlantic Ocean system.

Predictive species distribution modelling (SDM) has become an essential tool in biodiversity conservation and management. The choice of grain size (resolution) of environmental layers used in modelling is one important factor that may affect predictions. We applied 10 distinct modelling techniques to presence-only data for 50 species in five different regions, to test whether: (1) a 10-fold coarsening of resolution affects predictive performance of SDMs, and (2) any observed effects are dependent on the type of region, modelling technique, or species considered. Results show that a 10 times change in grain size does not severely affect predictions from species distribution models. The overall trend is towards degradation of model performance, but improvement can also be observed. Changing grain size does not equally affect models across regions, techniques, and species types. The strongest effect is on regions and species types, with tree species in the data sets (regions) with highest locational accuracy being most affected. Changing grain size had little influence on the ranking of techniques: boosted regression trees remain best at both resolutions. The number of occurrences used for model training had an important effect, with larger sample sizes resulting in better models, which tended to be more sensitive to grain. Effect of grain change was only noticeable for models reaching sufficient performance and/or with initial data that have an intrinsic error smaller than the coarser grain size.

Aquest projecte presenta un estudi per a la implantació d’un Enterprise Resource Planning (ERP) en una empresa de muntatges elèctrics. Per a això es mostra una primera part teòrica on es dóna a conèixer tot el que comporta el terme ERP i el seu procés d'implantació. A continuació s'estudien els requeriments i necessitats de l'empresa objecte de l'estudi. Per a finalitzar, s'estudien tres solucions existents el mercat actual de ERP’s i es selecciona la que millor s'adapta a les necessitats i requeriments en vistes a una hipotètica implantació.

Purpose of reviewThis review provides information and an update on stereotactic radiosurgery (SRS) equipment, with a focus on intracranial lesions and brain neoplasms.Recent findingsGamma Knife radiosurgery represents the gold standard for intracranial radiosurgery, using a dedicated equipment, and has recently evolved with a newly designed technology, Leksell Gamma Knife Perfexion. Linear accelerator-based radiosurgery is more recent, and originally based on existing systems, either adapted or dedicated to radiosurgery. Equipment incorporating specific technologies, such as the robotic CyberKnife system, has been developed. Novel concepts in radiation therapy delivery techniques, such as intensity-modulated radiotherapy, were also developed; their integration with computed tomography imaging and helical delivery has led to the TomoTherapy system. Recent data on the management of intracranial tumors with radiosurgery illustrate the trend toward a larger use and acceptance of this therapeutic modality.SummarySRS has become an important alternative treatment for a variety of lesions. Each radiosurgery system has its advantages and limitations. The 'perfect' and ubiquitous system does not exist. The choice of a radiosurgery system may vary with the strategy and needs of specific radiosurgery programs. No center can afford to acquire every technology, and strategic choices have to be made. Institutions with large neurosurgery and radiation oncology programs usually have more than one system, allowing optimization of the management of patients with a choice of open neurosurgery, radiosurgery, and radiotherapy. Given its minimally invasive nature and increasing clinical acceptance, SRS will continue to progress and offer new advances as a therapeutic tool in neurosurgery and radiotherapy.

La investigación Condiciones para una arquitectura radical se ha desarrollado en el marco de la beca FI 2009-12; y también incluye una beca de movilidad BE-DGR 2009 por un período de seis meses de 2010 en Princeton University School of Architecture. Condiciones para una arquitectura radical tiene un objetivo general: trabajar las relaciones entre límite, experiencia y comunidad a partir de dos pilares: arte y tecnología. Son tres familias de conceptos y sus articulaciones complejas en el espacio común: para definir en última instancia, otros procesos posibles de gestión en la ciudad. La lucha ideológica está en pensar cual debería ser el futuro de las ciudades. El objetivo concreto de la tesis es la búsqueda de herramientas para abrir nuevos espacios en la ciudad donde materializar un cambio social y urbano. Para entender esta aproximación la investigación indaga en los momentos de acercamiento y simbiosis de la arquitectura a las tesis del arte y la tecnología: una mirada atenta a las condiciones de contexto. Se explora el cruce de algunas ideas emancipadoras que se formularon en diferentes momentos de la cultura - desde las vanguardias históricas hasta ahora- en los que se intuyó la importancia del sistema abierto -el paso del objeto al proceso- y su trasposición en arquitectura: una arquitectura y un urbanismo open source; son episodios en los que ha existido un cuestionamiento de las fronteras disciplinares y un interés por la apropiación convivencial de lo público. Algunas de aquellas ideas pueden repetirse en el contexto activo de unas nuevas condiciones.
