Planning and Comunity Development: Case Studies, presents the findings of the inter-university Seminar held on 28?29 July 2011 and organized by researchers from the Technical University of Madrid and the University of California, Berkeley, who were fortunate to have the presence of the renowned Professor John Friedmann. Professors, researchers and PhD students from our research groups presented their works as scientific communications that were enriched by the debate among the different researches who attended the Seminar. All of them appear in the picture below in front of the gate of Haviland Hall at UC Berkeley. This book analyses the concept of planning and its evolution so far, leading to the conceptualization of governance as an expression of the planning practice. It also studies the role of social capital and cooperation as tools for the community development. The conceptual analysis is complemented by the development of six case studies that put forward experiences of planning and community development carried out in diverse social and cultural contexts of Latin-America, Europe and North America. This publication comes after more than 20 years of work of the researchers that met at the seminar. Through their work in managing development initiatives, they have learned lessons and have contribute to shape their own body of teaching that develops and analyses the role of planning in public domain to promote community development. This knowledge is synthesized in the model Planning as Working With People, that shows that development is not effective unless is promoted in continuous collaboration with all the actors involved in the process.

The agrifood industry, like other sectors, faces the ongoing challenge of improving their competitiveness in order to strengthen its market presence and cater to the growing global population. This research measures the competitiveness of the agrifood industry in the region of La Alcarria Conquense (Spain), in the framework of the evaluation of programs in the territory that have aimed at improving and enhancing this sector. Through building the competitiveness profiles (Porter, 1990) and cluster analysis we have identified six competitive strategy patterns in food companies in the region. In addition, we have analyzed each of the areas of competitiveness and we can identify the strengths and weaknesses of the sector, and identify recommendations for increasing the responsiveness of the territory. Among the defining characteristics are the lack of association, the limitation on payment systems or virtual absence of training and innovation. However, programs to support the sector are highly valued and reverse in the long-term viability of these companies.

El comportamiento dinámico de los puentes de ferrocarril, tanto convencional como de alta velocidad, constituye uno de los criterios de diseño más relevantes en la actualidad, puesto que bajo situaciones resonantes la amplificación dinámica que se produce puede llegar a ser muy elevada, no resultando válidas las metodologías utilizadas tradicionalmente. De igual forma, la amplificación dinámica suele llevar asociada la aparición de inestabilidades de la vía relacionadas con vibraciones excesivas de la capa de balasto, las cuales comprometen los estados límite de servicio de la estructura y por lo tanto no permiten garantizar el confort de los pasajeros. Para analizar el comportamiento dinámico de estructuras semi-enterradas en líneas de alta velocidad se decide llevar a cabo el presente Trabajo Fin de Máster en colaboración con la Subdirección de Ingeniería e Innovación de Adif. En este contexto, los objetivos principales de esta investigación comprenden la revisión del estado actual de conocimiento relativo a cálculo y evaluación dinámica, el análisis de tipologías de estructuras semi-enterradas de alguna de las líneas de alta velocidad gestionadas por Adif, así como la elaboración de distintos modelos numéricos de Elementos Finitos que permitan contrastar las medidas experimentales obtenidas en la campaña de instrumentación realizada. Por tanto, se realiza un estudio detallado del paso inferior seleccionado como representativo de la LAV Madrid - Barcelona - Frontera Francesa por medio de modelos numéricos en 2 y 3 dimensiones, desarrollados en FEAP v8.1 (2007). Estos modelos son calibrados en base a las aceleraciones máximas registradas en la campaña instrumental, así como al estudio del contenido frecuencial de cada uno de los sensores dispuestos. La resolución de los modelos se lleva a cabo por medio de una descomposición modal. Por último, en lo que se refiere a resultados obtenidos, destacar que los modelos desarrollados tras la calibración reproducen de forma fiel el comportamiento dinámico del paso inferior seleccionado bajo el eje activo de circulación. Así, se puede concluir que este tipo de estructuras semi-enterradas no se ven comprometidas ante la acción dinámica de las composiciones ferroviarias consideradas, tanto para las velocidades actuales de circulación como para previsibles incrementos de estas.

Rural communities in Cuenca (Spain) are characterized by a great social dislocation, mostly due to the low population density in these areas. In this way, the existence of groups of citizens able to be active agents of their development process is a critical aspect for any community-based development process in this Spanish region. The Institute of Community Development of Cuenca (IDC) has been working with this type of groups for the last 30 years focusing on the organizational empowerment of the rural communities. Main tools in this process have been the empowerment evaluation approach and the critical friend role when helping the groups to achieve their objectives and reinforcing them. This chapter analyses the empowerment process and how the critical friend role is nourished by the facilitator figure.

Medical imaging has become an absolutely essential diagnostic tool for clinical practices; at present, pathologies can be detected with an earliness never before known. Its use has not only been relegated to the field of radiology but also, increasingly, to computer-based imaging processes prior to surgery. Motion analysis, in particular, plays an important role in analyzing activities or behaviors of live objects in medicine. This short paper presents several low-cost hardware implementation approaches for the new generation of tablets and/or smartphones for estimating motion compensation and segmentation in medical images. These systems have been optimized for breast cancer diagnosis using magnetic resonance imaging technology with several advantages over traditional X-ray mammography, for example, obtaining patient information during a short period. This paper also addresses the challenge of offering a medical tool that runs on widespread portable devices, both on tablets and/or smartphones to aid in patient diagnostics.

Context. We report the infrared identification of the X-ray source 2XMM J191043.4+091629.4, which was detected by XMM-Newton/EPIC in the vicinity of the Galactic supernova remnant W49B. Aims. The aim of this work is to establish the nature of the X-ray source 2XMM J191043.4+091629.4 studying both the infrared photometry and spectroscopy of the companion. Methods. We analysed UKIDSS images around the best position of the X-ray source and obtained spectra of the best candidate using NICS in the Telescopio Nazionale Galileo (TNG) 3.5-m telescope. We present photometric and spectroscopic TNG analyses of the infrared counterpart of the X-ray source, identifying emission lines in the K-band. The H-band spectra does not present any significant feature. Results. We have shown that the Brackett γ H i at 2.165 μm, and He i at 2.184 μm and at 2.058 μm are significantly present in the infrared spectrum. The CO bands are also absent from our spectrum. Based on these results and the X-ray characteristics of the source, we conclude that the infrared counterpart is an early B-type supergiant star with an E(B − V) = 7.6 ± 0.3 at a distance of 16.0 ± 0.5 kpc. This would be, therefore, the first high-mass X-ray binary in the Outer Arm at galactic longitudes of between 30° and 60°.

We present an analysis of a series of four consecutive Chandra high-resolution transmission gratings observations, amounting to a total of 150 ks, of the Be X-ray source HD 119682 (=1WGA J1346.5–6255), a member of the new class of γ Cas analogs. The Chandra light curve shows significant brightness variations on timescales of hours. However, the spectral distribution appears rather stable within each observation and during the whole campaign. A detailed analysis is not able to detect any coherent pulsation up to a frequency of 0.05 Hz. The Chandra High Energy Transmission Gratings spectrum seems to be devoid of any strong emission line, including Fe Kα fluorescence. The continuum is well described with the addition of two collisionally ionized plasmas of temperatures kT ≈ 15 keV and 0.2 keV, respectively, by the apec model. Models using photoionized plasma components (mekal) or non-thermal components (powerlaw) give poorer fits, providing support for the pure thermal scenario. These two components are absorbed by a single column with N H = (0.20+0.15 –0.03) × 1022 cm–2 compatible with the interstellar value. We conclude that HD 119682 can be regarded as a pole-on γ Cas analog.

We present analysis of 100 ks contiguous XMM-Newton data of the prototypical wind accretor Vela X-1. The observation covered eclipse egress between orbital phases 0.134 and 0.265, during which a giant flare took place, enabling us to study the spectral properties both outside and during the flare. This giant flare with a peak luminosity of 3.92+0.42-0.09 × 1037 erg s-1 allows estimates of the physical parameters of the accreted structure with a mass of ~1021 g. We have been able to model several contributions to the observed spectrum with a phenomenological model formed by three absorbed power laws plus three emission lines. After analysing the variations with orbital phase of the column density of each component, as well as those in the Fe and Ni fluorescence lines, we provide a physical interpretation for each spectral component. Meanwhile, the first two components are two aspects of the principal accretion component from the surface of the neutron star, the third component seems to be the X-ray light echo formed in the stellar wind of the companion.

This multidisciplinary study concerns the optimal design of processes with a view to both maximizing profit and minimizing environmental impacts. This can be achieved by a combination of traditional chemical process design methods, measurements of environmental impacts and advanced mathematical optimization techniques. More to the point, this paper presents a hybrid simulation-multiobjective optimization approach that at once optimizes the production cost and minimizes the associated environmental impacts of isobutane alkylation. This approach has also made it possible to obtain the flowsheet configurations and process variables that are needed to manufacture isooctane in a way that satisfies the above-stated double aim. The problem is formulated as a Generalized Disjunctive Programming problem and solved using state-of-the-art logic-based algorithms. It is shown, starting from existing alternatives for the process, that it is possible to systematically generate a superstructure that includes alternatives not previously considered. The optimal solution, in the form a Pareto curve, includes different structural alternatives from which the most suitable design can be selected. To evaluate the environmental impact, Life Cycle Assessment based on two different indicators is employed: Ecoindicator 99 and Global Warming Potential.
