Wind Technology: A Framework for the Evaluation of Innovations’ Impacts on the Diffusion Potential

This paper proposes a framework based on which innovations in wind power technologies can be evaluated from the standpoint of their contribution to diffusion expansion. The framework helps build up a missing link between the technical literature on innovations and policy-oriented contributions concerned with the diffusion potential of wind power in national energy systems. The ideas are applied for the evaluation of wind technology innovations adopted in Spain. The framework can help policy-makers prioritize their innovation objectives and funding, so as to support the adoption of innovations that deserve the highest priority, given the country’s resources and energy system characteristics

The CMS High Level Trigger

The CMS experiment has been designed with a 2-level trigger system: the Level 1 Trigger, implemented on custom-designed electronics, and the High Level Trigger (HLT), a streamlined version of the CMS offline reconstruction software running on a computer farm. A software trigger system requires a tradeoff between the complexity of the algorithms running on the available computing power, the sustainable output rate, and the selection efficiency. Here we will present the performance of the main triggers used during the 2012 data taking, ranging from simpler single-object selections to more complex algorithms combining different objects, and applying analysis-level reconstruction and selection. We will discuss the optimisation of the triggers and the specific techniques to cope with the increasing LHC pile-up, reducing its impact on the physics performance.Comment: PIC2013 conferenc

Gelfand-Zetlin polytopes and flag varieties

I construct a correspondence between the Schubert cycles on the variety of complete flags in C^n and some faces of the Gelfand-Zetlin polytope associated with the irreducible representation of SL_n(C) with a strictly dominant highest weight. The construction is based on a geometric presentation of Schubert cells by Bernstein-Gelfand-Gelfand using Demazure modules. The correspondence between the Schubert cycles and faces is then used to interpret the classical Chevalley formula in Schubert calculus in terms of the Gelfand-Zetlin polytopes. The whole picture resembles the picture for toric varieties and their polytopes.Comment: 16 pages, 2 figure

Study of charged-particle multiplicities with ALICE

The multiplicity measurements include the pseudorapidity density, $\rm{d}N_{\rm ch}/\rm{d}{\eta}$, and the probability distribution as a function of the number of charged particles, $\rm{P}(N_{\rm ch})$. ALICE has measured the multiplicities for three collision systems, for proton-proton, proton-lead and lead-lead collisions at Run 1 and 2 at the Large Hadron Collider. A selection of these results will be presented in these proceedings, concluding with an overview of new measurements planned.Comment: 3 pages, 4 figures.

Evaluación del uso de la comunicación para el desarrollo en las intervenciones de conflicto. Medir la paz en la comunicación participativa

The application of Communication for Development (C4D) in conflict prevention, conflict reduction and post-conflict reconstruction interventions is a relatively new field. International organisations that have begun to adopt new communication & media designs in their peace work are progressively offering a credible baseline to engage in the assessment of this practice. In this paper, I offer a short compendium of the evaluation frameworks I have developed through my empirical research on the impact of Communication for Development in Peacebuilding; this is presented alongside a number of reflections and followed by concluding considerations on the state of the field.La aplicación de la Comunicación para el Desarrollo (C4D) en la prevención y reducción de conflictos, así como en la intervención para la reconstrucción cuando estos no pueden ser evitados, es un campo relativamente nuevo. Las organizaciones internacionales que han rediseñado su comunicación y medios en su trabajo para la consecución de la paz nos están ofreciendo de forma progresiva una base de referencia fiable para participar en la evaluación de esta práctica. En este trabajo presento un breve compendio de los marcos de evaluación que he desarrollado a través de mi investigación empírica sobre el impacto de la Comunicación para el Desarrollo en la consolidación de la Paz; un estudio que viene acompañado de una serie de reflexiones y seguido por unas conclusiones finales sobre el estado en el que este campo se encuentra en la actualidad
