El reformado marco europeo regulador de las telecomunicaciones: ¿Un avance para el Mercado Único?

Tras un proceso que había durado cuatro años, en los días finales de 2009 se publicaron las normas que reforman el marco europeo regulador de las telecomunicaciones. El nuevo marco no introduce grandes novedades respecto al precedente de 2002 que adoptó un enfoque más acorde con las reglas generales de defensa de la competencia, basando la regulación en la definición y análisis de mercados relevantes. Este trabajo analiza estas normas, y de modo general la política sobre telecomunicaciones de la Comisión, y evalúa su eficacia de cara al progreso del mercado único. Mercado único que afronta otros obstáculos: cumplido el plazo de dieciocho meses para la transposición a los respectivos ordenamientos internos de las nuevas Directivas, sólo una minoría de Estados miembros había cumplido con dicha obligación.

The Role of Patents in the Advent of Web 2.0

Given the significant impact of Web 2.0-related innovations on new Internet-based initiatives, this paper seeks to identify to what extent the main developments are protected by patents and whether patents have had a leading role in the advent of Web 2.0. The article shows that the number of patent applications filed is not that important for many of the Web 2.0 technologies in frequent use and that, of those filed, those granted are even less. The conclusion is that patents do not seem to be a relevant factor in the development of the Web 2.0 (and more generally in dynamic markets) where there is a high degree of innovation and low entry barriers for newcomers.

Particle methods parallel implementations by GP-GPU strategies

This paper outlines the problems found in the parallelization of SPH (Smoothed Particle Hydrodynamics) algorithms using Graphics Processing Units. Different results of some parallel GPU implementations in terms of the speed-up and the scalability compared to the CPU sequential codes are shown. The most problematic stage in the GPU-SPH algorithms is the one responsible for locating neighboring particles and building the vectors where this information is stored, since these specific algorithms raise many dificulties for a data-level parallelization. Because of the fact that the neighbor location using linked lists does not show enough data-level parallelism, two new approaches have been pro- posed to minimize bank conflicts in the writing and subsequent reading of the neighbor lists. The first strategy proposes an efficient coordination between CPU-GPU, using GPU algorithms for those stages that allow a straight forward parallelization, and sequential CPU algorithms for those instructions that involve some kind of vector reduction. This coordination provides a relatively orderly reading of the neighbor lists in the interactions stage, achieving a speed-up factor of x47 in this stage. However, since the construction of the neighbor lists is quite expensive, it is achieved an overall speed-up of x41. The second strategy seeks to maximize the use of the GPU in the neighbor's location process by executing a specific vector sorting algorithm that allows some data-level parallelism. Al- though this strategy has succeeded in improving the speed-up on the stage of neighboring location, the global speed-up on the interactions stage falls, due to inefficient reading of the neighbor vectors. Some changes to these strategies are proposed, aimed at maximizing the computational load of the GPU and using the GPU texture-units, in order to reach the maximum speed-up for such codes. Different practical applications have been added to the mentioned GPU codes. First, the classical dam-break problem is studied. Second, the wave impact of the sloshing fluid contained in LNG vessel tanks is also simulated as a practical example of particle methods

Experimental study on the effective width of flat slab structures under dynamic seismic loading

This paper investigates the effective width of reinforced concrete flat slab structures subjected to seismic loading on the basis of dynamic shaking table tests. The study is focussed on the behavior of corner slab? column connections with structural steel I- or channel-shaped sections (shearheads) as shear punching reinforcement. To this end, a 1/2 scale test model consisting of a flat slab supported on four box-type steel columns was subjected to several seismic simulations of increasing intensity. It is found from the test results that the effective width tends to increase with the intensity of the seismic simulation, and this increase is limited by the degradation of adherence between reinforcing steel and concrete induced by the strain reversals caused by the earthquake. Also, significant differences are found between the effective width obtained from the tests and the values predicted by formula proposed in the literature. These differences are attributed to the stiffening effect provided by the steel profiles that constitute the punching shear reinforcement.

Análisis Empírico del Papel de las Competencias Generales en el Marco de los Estudios Superiores.

En plena implantación de los nuevos planes de estudio de acuerdo al EEES, las universidades se enfrentan a un nuevo modelo educativo basado en competencias: competencias específicas y competencias generales. Las competencias específicas están asociadas a la adquisición y desarrollo de conocimientos de un área en particular, mientras que las competencias generales son transversales al plan de estudios y definen capacidades, habilidades y/o aptitudes que el alumno debe desarrollar para aplicarlas a lo largo de su carrera profesional. El objetivo de este trabajo es proporcionar una guía al docente sobre las posibles mejoras para tratar el mayor número de competencias generales satisfactoriamente. Concretamente, se ha analizado la manera en la que los docentes están promoviendo y desarrollando las competencias generales con el objetivo de detectar carencias, mejoras y necesidades. El análisis se ha realizado sobre el profesorado de la Titulación de Graduado en Ingeniería del Software de la Universidad Politécnica de Madrid.

Economics and forecast of energy consumption in NGN networks: the case of Spain

Reducing energy consumption is one of the main goals of sustainability planning in most countries. For instance in Europe, the EC established the objectives in the Communication “20 20 by 2020 Europe's climate change opportunity”.

On the economics of energy consumption in 4G networks: the case of Spain

Reducing energy consumption is one of the main challenges in most countries. For example, European Member States agreed to reduce greenhouse gas (GHG) emissions by 20% in 2020 compared to 1990 levels (EC 2008). Considering each sector separately, ICTs account nowadays for 2% of total carbon emissions. This percentage will increase as the demand of communication services and applications steps up. At the same time, the expected evolution of ICT-based developments - smart buildings, smart grids and smart transportation systems among others - could result in the creation of energy-saving opportunities leading to global emission reductions (Labouze et al. 2008), although the amount of these savings is under debate (Falch 2010). The main development required in telecommunication networks ?one of the three major blocks of energy consumption in ICTs together with data centers and consumer equipment (Sutherland 2009) ? is the evolution of existing infrastructures into ultra-broadband networks, the so-called Next Generation Networks (NGN). Fourth generation (4G) mobile communications are the technology of choice to complete -or supplement- the ubiquitous deployment of NGN. The risk and opportunities involved in NGN roll-out are currently in the forefront of the economic and policy debate. However, the issue of which is the role of energy consumption in 4G networks seems absent, despite the fact that the economic impact of energy consumption arises as a key element in the cost analysis of this type of networks. Precisely, the aim of this research is to provide deeper insight on the energy consumption involved in the usage of a 4G network, its relationship with network main design features, and the general economic impact this would have in the capital and operational expenditures related with network deployment and usage.

Un Primer Paso a la agilidad: Retrospectivas para el aprendizaje de la ingeniería del SW

En los últimos años la industria software demanda, cada vez más, ingenieros que posean conocimientos y experiencia en la aplicación de metodologías ágiles. Los principios y valores en los que se basan las metodologías ágiles fomentan la adquisición de competencias como la capacidad de organización, el trabajo en equipo, la comunicación, o el liderazgo, entre otras, denominadas en el marco del Espacio Europeo de Educación Superior (EEES) como competencias generales o transversales. Ambas razones justifican la adopción de las metodologías ágiles como métodos de aprendizaje activos, es decir, la implantación de metodologías ágiles durante el ciclo formativo del ingeniero software. Esta apuesta se ha materializado en el proyecto de innovación educativa Agile Learning - Aprendizaje Ágil, cuyos primeros pasos, resultados y lecciones aprendidas se presentan en este artículo.

Modelo de gestión por proyectos para el desarrollo local (MGPDL) en el marco de la nueva gestión pública. Aplicación a los distritos y barrios de la ciudad de Madrid

Esta investigación presenta un modelo de gestión para el ámbito público local enmarcado en la Nueva Gestión Pública que aboga por una gestión más eficaz, eficiente y transparente, y que pone el acento en la consideración del administrado como cliente y en las capacidades gerenciales y de liderazgo de los directivos públicos por encima de la función burocrática clásica. Asumiendo el concepto de comunidad política, en el que los ciudadanos y los gobernantes son corresponsables de la concertación política y social, y se pone en valor el conocimiento de la sociedad civil para la toma de decisiones, este modelo se expresa a través de un plan de acción para el desarrollo local que incorpora la estrategia empresarial “gestión por proyectos”, entendidos éstos como todos los proyectos que recogen las necesidades e ideas de los afectados, y que de alguna manera contribuyen al cambio o ayudan a transformar la realidad para la mejora de la calidad de vida. La realidad objeto de estudio que inspira este modelo es el primer plan de inversiones llevado a cabo en los distritos madrileños de Villaverde y Usera. Las características propias de este plan fueron la voluntad y la habilidad de los poderes públicos para transformar una movilización social reivindicativa en un proceso de planificación como aprendizaje social, integrando a los ciudadanos en un innovador sistema de gestión de responsabilidad compartida. El resultado fue considerado un éxito, ya que se cumplió el objetivo de reequilibrio social y económico de ambos distritos con el conjunto de la ciudad de Madrid, gracias a las infraestructuras y equipamientos construidos, y a los programas sociales implementados. De hecho, al concluir el plan, los problemas que originaron la movilización social apenas tenían relevancia: droga (5%), falta de equipamientos (3%) y baja calidad de vida (5%). A raíz del aprendizaje de esta experiencia desarrollada durante el período 1998‐ 2003, se construyó una metodología de actuación que se ha materializado en los actuales Planes especiales de actuación en distritos y Planes de Barrio de la ciudad de Madrid. Las evaluaciones realizadas hasta ahora determinan que se está logrando una homogeneización territorial en la oferta municipal de bienes, servicios y equipamientos públicos, lo que contribuye a una mayor equidad económica y social, en definitiva, a una mejor calidad de vida. ABSTRACT This research presents a management model for the public sector local framed in the New Public Management that advocates a public management more effective, efficient and transparent, and that puts the accent on the consideration of the citizen as client and in managerial and leadership skills of public managers over the classic bureaucratic function. Embracing the concept of political community, in which citizens and governments are jointly responsible for the political and social dialogue, and highlights the knowledge of the civil society to the decision‐making, this model is expressed through an action plan for local development that incorporates the business strategy "management by projects', understood these as all the projects that reflected the needs and ideas of those affected, and that in some way contribute to the change or help to transform the reality for the improvement of the quality of life. The reality which is subject of study and inspires this model is the first investment plan carried out in the districts of Madrid Villaverde and Usera. The characteristics of this plan were the will and the ability of the public authorities to transform a social mobilization in a planning process as social learning, integrating to citizens in an innovative system of management of shared responsibility. The result was considered a success, since the target was met for social and economic balance of the two districts with the whole of the city of Madrid, thanks to the built infrastructure and equipment, and the social programs implemented. In fact, at the end of the plan, the problems that led to the social mobilization had little relevance: drugs (5 %), lack of equipment (3 %) and low quality of life (5 %). As a result of learning from this experience developed during the period 1998‐ 2003, was built a methodology of performance which has been materialized in the current plans for special action in districts and plans of neighborhood of the city of Madrid. The evaluations conducted until now determine that the plans are achieving a territorial homogenization in the municipal supply of goods, services and public facilities, which contributes to a better economic and social equity, ultimately, to a better quality of life.

How much energy will your NGN consume? A model for energy consumption in next generation access networks: The case of Spain

The contribution to global energy consumption of the information and communications technology (ICT) sector has increased considerably in the last decade, along with its growing relevance to the overall economy. This trend will continue due to the seemingly ever greater use of these technologies, with broadband data traffic generated by the usage of telecommunication networks as a primary component. In fact, in response to user demand, the telecommunications industry is initiating the deployment of next generation networks (NGNs). However, energy consumption is mostly absent from the debate on these deployments, in spite of the potential impact on both expenses and sustainability. In addition, consumers are unaware of the energy impact of their choices in ultra-broadband services. This paper focuses on forecasting energy consumption in the access part of NGNs by modelling the combined effect of the deployment of two different ultra-broadband technologies (FTTH-GPON and LTE), the evolution of traffic per user, and the energy consumption in each of the networks and user devices. Conclusions are presented on the levels of energy consumption, their cost and the impact of different network design parameters. The effect of technological developments, techno-economic and policy decisions on energy consumption is highlighted. On the consumer side, practical figures and comparisons across technologies are provided. Although the paper focuses on Spain, the analysis can be extended to similar countries.
