Title: Identificación de la estructura urbana del Algarve (Portugal) mediante el valor de interacción Authors: Moix Bergadà, Montserrat; Faria de Deus, Raquel; Roca Cladera, Josep; Tenedorio, José Antonio Abstract: Muchos estudios tienen como referencia la ciudad, analizándola y comparándola desde diferentes perspectivas y para multitud de finalidades. La división administrativa, propia de cada territorio, sirve generalmente de unidad de partida, sin cuestionar el ámbito que abarcan las ciudades reales, su área de influencia, su estructura interna... lo cual dificulta la comparación entre realidades urbanas de distintos territorios, acentuándose cuando se trata de diferentes países. Aunque la metodología desarrollada a partir del Valor de Interacción permite delimitar la estructura urbana mediante las relaciones funcionales que se establecen entre el mercado de trabajo y el de residencia, la necesidad de obtener la escala local o urbana exige disponer de la matriz de movilidad obligada por trabajo para unidades administrativas pequeñas (el ámbito local). En el caso de Portugal los municipios, concelhos, son muy extensos y aunque existe una división inframunicipal, la freguesia, el Censo sólo registra los desplazamientos entre freguesia de residencia y concelho de trabajo. Así, este trabajo propone identificar el sistema urbano del distrito de Faro de Portugal a partir de las freguesias, estimando para ello los flujos originados por la movilidad obligada por trabajo entre estas entidades inframunicipales.

Title: Modelling shoreline sand waves: application to the coast of Namibia Authors: Falqués Serra, Albert; Van den Berg, Niels; Ribas Prats, Francesca; Caballeria Suriñach, Miquel Abstract: The SW coast of Africa (Namibia and part of Angola) features very long sandy beaches and a wave climate dominated by energetic swells from the SSW, therefore approaching the coast with a very high obliquity. Satellite images reveal that along that coast there are many shoreline sand waves with wavelengths ranging from 2 to 8 km. A more detailed study, including a Fourier analysis of the shoreline position, confirms a high spectral density concentration at these lengths scales. Also, it becomes apparent that at least some of the sand waves are dynamically active rather than being controlled by the geological setting. A morphodynamic model is used to test the hypothesis that these sand waves could emerge as free morphodynamic instabilities of the coastline due to the obliquity in wave incidence. It is found that the wave period, Tp, is crucial to establish the tendency to stability or instability, instability increasing for decreasing period, whilst there is some discrepancy in the observed periods. Model results for Tp = 7 s clearly show the tendency for the coast to develop free sand waves at 2 km wavelength within a few years, which migrate to the north at rates of 0.6-0.7 km/yr. For Tp = 8 s, instability is weaker and rather sensitive to other factors as the underlying bathymetry. In this case, the coast seems to be nearly at neutral stability so that sand waves originated from other mechanisms can propagate downdrift with little decay.

Title: Efficient margin adaptive scheduling for MIMO-OFDMA systems Authors: Moretti, Marco; Pérez Neira, Ana Isabel Abstract: In this paper we address the problem of margin adaptive scheduling in the downlink of an orthogonal frequency division multiple access (OFDMA) multiple-input multiple-output (MIMO) system. Optimal resource allocation in MIMO systems requires the joint optimization of: a) linear transmit and receive spatial filters, b) channel assignment and c) power allocation. This problem is not convex and its complexity becomes thus intractable already for small sets of users and subcarriers. To reduce the complexity of the problem at hand, we propose a novel heuristic strategy that partitions the users in different groups according to their average channel quality and addresses the original problem by solving a succession of lower-complexity allocation problems. The spatial dimension is employed to prevent multiple access interference from hindering the performance of the sequential allocation. To further reduce the complexity burden we introduce a linear programming formulation in combination with a waterfilling-based strategy to allocate channels and power to the groups of users. Numerical results and evaluation of the computational complexity show that, though suboptimal, in most cases the proposed algorithm manages to exploit in an original way the inherent multi-user diversity of multi-carrier systems to ease the task of resource allocation with a very limited performance loss from the theoretic optimum.

Title: Rehabilitación energética de edificios escolares en clima mediterráneo: caso de estudio, Barcelona Authors: Bosch González, Montserrat; Rodríguez Cantalapiedra, Inma; Álvarez del Castillo, Javier Abstract: necesidad de reducir el consumo energético se hace cada día más evidente, especialmente en Europa debido a su situación de dependencia energética de países externos a la Unión y también por razones relacionadas con el impacto ambiental y las emisiones asociadas. En este contexto, la rehabilitación energética de edificios es una línea de trabajo prioritaria que actúa sobre el parque edificado, y los edificios públicos deben ser un modelo o ejemplo para impulsar este tipo de actuaciones. Los centros docentes, con un potencial de ahorro muy importante y con unos consumos energéticos asociados básicamente a dos grandes conceptos, la iluminación y la climatización, pueden considerarse como un laboratorio de investigación en cuanto a eficiencia energética. A partir de las experiencias adquiridas durante más de 10 años se ha desarrollado una metodología de análisis para la intervención en edificios docentes en Barcelona con los siguientes objetivos: definir los indicadores estratégicos para identificar las oportunidades de ahorro, evaluar las posibles medidas de reducción de consumos a partir de la limitación de la demanda, analizar y dar contenido al papel de cada uno de los actores que intervienen en las estrategias de uso y gestión de los edificios escolares y establecer los criterios que deben considerarse para realizar las futuras intervenciones de rehabilitación energética. El método, como manera de pensar ordenadamente, ha de permitir optimizar los recursos y descubrir les rutas de trabajo que nos conduzcan al objetivo final: reducir el consumo energético del parque edificado

Title: Experimental study on resistance to cracking of bituminous mixtures using the Fénix Test Authors: Pérez Jiménez, Félix Edmundo; Botella Nieto, Ramón; Valdés Vidal, Gonzalo Abstract: The Road Research Laboratory of the Technical University of Catalonia (UPC) has developed a new tensile test called Fénix test. The objective of this test is to evaluate bituminous mixture crack behaviour. It is a simple procedure and has a low cost set up. The aim of this paper is to present Fénix test as a procedure to determine crack resistance through calculation of dissipated energy during the process. Test procedure and data analysis are shown for different types of mixtures. Variables studied were load application velocity, aging, binder type, binder content, test temperature and compaction temperature. As a result, authors found out that Fénix test is an effective procedure to determine mechanical properties regarding cracking resistance of bituminous mixtures.

Title: Boron diffused emitters passivated with Al2O3 films Authors: Masmitja Rusinyol, Gerard; Ortega Villasclaras, Pablo Rafael; López Rodríguez, Gema; Calle Martin, Eric; García Molina, Francisco Miguel; Martín García, Isidro; Orpella García, Alberto; Voz Sánchez, Cristóbal; Alcubilla González, Ramón Abstract: In this work we study the fabrication and characterization of boron diffused emitters using FZ c-Si(n) substrates. Emitter surface was passivated with Al2O3(25 nm thick) layers deposited by thermal atomic layer deposition ALD technique. This study covers a broad emitter sheet resistance Rsh range from 20 to 250 ?/sq using both polished and textured wafers. Emitter electrical quality was tested by means of lifetime measurements using quasi-stationary photoconductance QSS-PC method. Dark saturation emitter current densities Joe's were extracted from lifetime measurements resulting in Joe's values ranging from 10 to 150 fA/cm2 depending on Rsh. These results are in the-state-of-the-art in boron emitter passivation.

Title: ARBRES: Light-weight CW/FM SAR sensors for small UAVs Authors: Aguasca Solé, Alberto; Acevo Herrera, René; Broquetas Ibars, Antoni; Mallorquí Franquet, Jordi Joan; Fabregas Canovas, Francisco Javier Abstract: This paper describes a pair of compact CW/FM airborne SAR systems for small UAV-based operation (wingspan of 3.5 m) for low-cost testing of innovative SAR concepts. Two different SAR instruments, using the C and X bands, have been developed in the context of the ARBRES project, each of them achieving a payload weight below 5 Kg and a volume of 13.5 dm3 (sensor and controller). Every system has a dual receiving channel which allows operation in interferometric or polarimetric modes. Planar printed array antennas are used in both sensors for easy system integration and better isolation between transmitter and receiver subsystems. First experimental tests on board a 3.2 m wingspan commercial radio-controlled aircraft are presented. The SAR images of a field close to an urban area have been focused using a back-projection algorithm. Using the dual channel capability, a single pass interferogram and Digital Elevation Model (DEM) has been obtained which agrees with the scene topography. A simple Motion Compensation (MoCo) module, based on the information from an Inertial+GPS unit, has been included to compensate platform motion errors with respect to the nominal straight trajectory.

Title: Multiport small integrated antenna impedance matrix measurement by backscattering modulation Authors: Monsalve, Beatriz; Blanch Boris, Sebastián; Romeu Robert, Jordi Abstract: A method to characterize small antennas in their actual operating conditions is presented. The proposed procedure is based on the radar cross section (RCS) measurement technique using backscattering modulation. A theoretical description of the measurement setup based on the signal flow graph representation is presented. The experimental validation includes the measurement of one and two port antennas, as well as the measurement of a small integrated antenna. Results show how the effect of the environment on the antenna impedance can be adequately measured with the proposed system.

Title: Decomposed radio access network over deployed passive optical networks using coherent optical OFDM transceivers Authors: Fabrega Sanchez, Josep Maria; Svaluto Moreolo, Michela; Chocol, Marcin; Junyent Giralt, Gabriel Abstract: In this paper, it is proposed to take advantage of the deployed passive optical network (PON) infrastructure by overlaying a decomposed radio access network (RAN) using a very dense WDM. Coherent optical orthogonal frequency-division multiplexing technology is investigated for achieving the desired narrow channel spacings while minimizing the impact on the performance of legacy equipment. A practical implementation is evaluated using simulations. Within the analyzed configurations, a trade-off is found between time-division multiplexed (TDM)-PON and RAN performance. The optimum balance is found for additional losses in the TDM-PON path of less than 1 dB, ensuring simultaneous service to a maximum of 145 metro cells together with the PON customers and within a reach of 24 km.

Title: Structural transitions of nylon 47 and clay influence on its crystallization behavior Authors: Morales Gámez, Laura Teresa; Casas Becerra, María Teresa; Franco García, María Lourdes; Puiggalí Bellalta, Jordi Abstract: Basic diffraction data on nylon 47 pointed out a peculiar structure of hydrogen bonds along two directions. Nylon 47 showed reversible polymorphic transitions during heating/cooling processes that were analyzed by real time synchrotron WAXD experiments. Results indicated that nylon 47 had a first structural transition at low temperature, followed by a gradual Brill transition towards a pseudohexagonal packing. Nylon 47 crystallized from the melt giving rise to spherulites with different characteristics than those attained with conventional even-even nylons. Interestingly, spherulites crystallized at low supercooling underwent a reversible change in birefringence with temperature. This was due to the reversible structural changes caused by temperature variations and the flat on lamellar morphology. Intercalated and exfoliated nanocomposites based on nylon 47 were prepared by solution intercalation and melt mixing using Cloisites 25A and 30B. The influence of the final silicate layer morphology on the hot crystallization behavior was investigated. Crystallization rates of the neat polymer and its two nanocomposites were significantly different, mainly due to variations in the primary nucleation

Title: Spencer–Attix water/medium stopping-power ratios for the dosimetry of proton pencil beams Authors: Gomà, Carles; Andreo, Pedro; Sempau Roma, Josep Abstract: This paper uses Monte Carlo simulations to calculate the Spencer-Attix water/medium stopping-power ratios (sw, med) for the dosimetry of scanned proton pencil beams. It includes proton energies from 30 to 350 MeV and typical detection materials such as air (ionization chambers), radiochromic film, gadolinium oxysulfide (scintillating screens), silicon and lithium fluoride. Track-ends and particles heavier than protons were found to have a negligible effect on the water/air stopping-power ratios (sw, air), whereas the mean excitation energy values were found to carry the largest source of uncertainty. The initial energy spread of the beam was found to have a minor influence on the sw, air values in depth. The water/medium stopping-power ratios as a function of depth in water were found to be quite constant for air and radiochromic film - within 2.5%. Also, the sw, med values were found to have no clinically relevant dependence on the radial distance - except for the case of gadolinium oxysulfide and proton radiography beams. In conclusion, the most suitable detection materials for depth-dose measurements in water were found to be air and radiochromic film active layer, although a small correction is still needed to compensate for the different sw, med values between the plateau and the Bragg peak region. Also, all the detection materials studied in this work - except for gadolinium oxysulfide - were found to be suitable for lateral dose profiles and field-specific dose distribution measurements in water
