Title: Performance of a spatial error correction technique in SMOS brightness temperature images Authors: Wu, Lin; Torres Torres, Francisco; Corbella Sanahuja, Ignasi; Duffo Ubeda, Núria; Martín Neira, Manuel Abstract: Soil Moisture and Ocean Salinity (SMOS) brightness temperature synthesized images are obtained after a comprehensive calibration and error correction procedure. However, the final images are still contaminated by small but non-negligible spatial errors: the so-called pixel bias. These errors have been found to be very stable in the SMOS Alias-Free Field of View (AF-FoV) and can be mitigated, to a large extent, by applying a multiplicative mask to the measured brightness temperatures at the antenna plane. This paper describes the procedure to upgrade this mask to cover SMOS Extended AF­ FoV.

Title: Sinopsis y notas de trabajo sobre autocad: inventario y propuestas Authors: Nogués Mañé, Carlos Abstract: En los últimos años de docencia he venido redactando cortas monografías para poner en orden mis propias ideas y fijar conclusiones sobre el funcionamiento de AutoCAD en sus distintas versiones, porque los manuales suelen pasar de puntillas sobre las cuestiones espinosas. También los recorridos transversales, sobre los diferentes temas que afectan a una cuestión o su evolución a lo largo de sucesivas versiones, son recomendables para contrarrestar la excesiva parcelación de las exposiciones sistemáticas. De todo este material, sólo una parte ha sido incluida en los apuntes de clase porque el resto es más bien letra pequeña sólo apta para especialistas, si bien podría ser útil su difusión aunque sólo fuera para evitar a sus potenciales lectores quemar muchas horas frente al ordenador: dado el mutismo o poca claridad de los manuales, la vía empírica es el único medio para alcanzar certezas. Como supongo que numerosos profesionales y docentes, con AutoCAD como herramienta habitual u objeto de estudio, deben compartir tales inquietudes y hábitos, presento un inventario de las 30 fichas realizadas hasta ahora, a disposición de cuantos acepten la filosofía del "quid pro quo". Incluyo la invitación a colaborar, por puro placer, en el diseño de un simulador de reactivo posicional de cursor. ABSTRACT During the past few years, in view of the tendency of manuals to pass quickly over difficult issues, I have written several short articles on the different versions of AutoCAD. Also, the excessive divisions used in most systematic presentations mean that a lateral overview, looking at the different themes that affect an issue or its evolution through successive versions, is advisab le and a welcome contrast. From all this material, only a small amount has been included in the class notes since the rest is really the small print which is only of interest to the expert. However, it could well be useful to publish it, if only to ensure that potential readers do not waste many hours glued to their compared screens: in view of the lack of clarity in the manuals, experience is the only way to arrive at certain results. As I suppose that many professionals and educators (who use AutoCAD as an everyday tool, or who study it) must share my concerns and methods, I am providing a list of the 30 files I have written so far. They are available to all those who accept the philosophy of "quid pro quo". I would also like to invite anyone who is interested in collaborating, for the pure pleasure of it, in the design of a cursor position reactor simulator.

Title: AutoCAD: adaptación de un bloque ortonormal 2d(3d) a un paralelogramo (paralelepípedo) dado Authors: Nogués Mañé, Carlos Abstract: Si se ha tenido la precaución de referir a un bloque 2D un cuadrado unitario ortogonal, será inmediato insertarlo de manera que éste se adapte a cualquier marco rectangular establecido en el dibujo. Sin embargo, la inmediatez desaparece si pretendemos encadenar inserciones de manera que, además de una combinación simple de escalado, giro y traslación, se halle implícita una transformación de cortadura: cuando el marco receptor sea un paralelógramo oblicuo. Porque está claro que si insertamos el bloque girado, convertimos la inserción en bloque y volvemos a insertar, esta vez con escalado no uniforme, la figura transformada del primitivo cuadrado de referencia será un paralelógramo, pero el problema es: dado un marco romboidal concreto, ¿con qué giro hay que realizar la primera inserción, y qué giro y factores de escala debemos aplicar a la segunda para que el cuadrado de referencia se ciña al marco? El problema se complica si queremos aprovechar el resultado de la primera inserción para adaptaciones a otros paralelógramos, creando un si stema no redundante de inserciones intermedias, pero se ha diseñado un programa AutoLISP que resu elve estas cuestiones en 2D, en 3D y puede operar con bloques con atributos, no sólo situados en el plano base sino ubicados y orientados libremente. ABSTRACT If we reference an orthogonal unit square to a 2D-block, the block can immediately be inserted in such a way that the orthogonal unit square adapts to any existing rectangular frame in the drawing. However, this immediacy is lost if we wish to perform a series of insertions in such a way that, in addition to a simple combination of scaling, rotating and translating, they implicitly include a shearing transformation when the receiving frame is an oblique parallelogram. This is because if we rotate the block and then insert it, convert the insertion into a block and reinsert (this time using a non-uniform scale factor), the figure resulting from this transformation of the original reference square will be a parallelogram. However, the question we wish to tackle is the following. Given a specific rhomboid frame, exactly what rotation do we need when making the first insertion, and what rotation and scale factors must we apply when inserting for the second time, in order to ensure that the reference square fits the frame exactly? The problem becomes more complicated if we wish to use the result of the first insertion and adapt it for other parallelograms, creating a non-redundant system of intermediate insertions. An AutoLISP program has been designe d which solves these problems in 2D and in 3D. Furthermore, it can cope with blocks that do not sit squarely on the flat base, but which are arbitrarily located and orientated.

Title: Testing a new submersible drill rig Authors: Romero, F.; Devincenzi, M.J.; Pérez Garcia, N.; Arroyo Alvarez de Toledo, Marcos; Deu, Amadeu Abstract: The paper describes the main features and initial underwater field-testing results of a remotely operated submersible drill rig designed to obtain continuous cores of soil and/or rock up to 6m long in water depths of 200m. The rig mast angle is hydraulically actuated covering 90° of altitude. This enables both a fully horizontal position used for deployment onto, and recovery of the rig from, the seabed, as well as a fully vertical position during coring. The frame is equipped with positioning and inclination sensors for accurate register of core orientation. Coring equipment with diameter of up to 133mm can be mounted in the rig, thus enabling the recovery of relatively large-diameter cores. The coring operation is fully instrumented and all the drill operation parameters such as torque, thrust, advance, injection rate and pressure are recorded. The equipment is deployable from a variety of platforms.

Title: Energy-efficiency and security issues in the Cisco Nexus virtual distributed switching Authors: Peterson, Benjamin; Ricciardi, Sergio; Nin Guerrero, Jordi Abstract: Virtualization technologies have brought with them the promise of increased security and energy saving. Such was the case with the Cisco Nexus virtual switching environment. However, possible security issues of this environment have not been evaluated and the achievable energy savings have not been quantified yet. In particular, it was necessary to investigate whether the security vulnerabilities existing in physical switches had persisted into the virtual environment. This paper provides an evaluation of the energy saving and an analysis of the security implications of the Cisco Nexus virtual distributed switching environment.

Title: Desarrollo de herramientas para la evaluación preliminar de la peligrosidad de corrientes detríticas Authors: Bregoli, Francesco; Bateman Pinzón, Allen; Medina Iglesias, Vicente César de; Hurlimann Ziegler, Marcel Abstract: Con el objetivo de proporcionar recomendaciones para la alerta temprana de fenómenos potencialmente desencadenantes de corrientes detríticas (“Debris Flow”), uno de los temas principales es la identificación preliminar de zonas de riesgo. Esta identificación es sustancialmente diferente de los mapas de riesgo que se suelen realizar por las autoridades de cuenca con el fin de dar una guía para planes de gestión del territorio. En el caso de alerta temprana, una identificación más aproximativa de las zonas de riesgo es suficiente. En esta perspectiva, los dos componentes del riesgo, peligrosidad y vulnerabilidad, se pueden estimar de una manera simplificada. En este trabajo se han desarrollado unas herramientas para la evaluación rápida de peligro por corrientes detríticas. Se han adaptado metodologías existentes y modelos simplificados y se ha llevado a cabo un útil paquete común de metodologías para una rápida evaluación de la peligrosidad. Se modelan tanto la iniciación como la propagación de corrientes detríticas. Uno de los requisitos del proyecto es definir una herramienta utilizable en diferentes contextos donde el nivel de detalle en los datos de entrada puede ser muy variado. Para lograr este objetivo se define un enfoque multinivel. La metodología se aplica en tres cuencas con características diferentes.

Title: Mitigation of the finger loading effect in handset antennas Authors: Anguera Pros, Jaume; Andujar, Aurora; Camps, Albert; Puente Baliarda, Carles; Picher, Cristina Abstract: The effect of the human body over the radiation of handset antennas is a critical issue that have to be considered to ensure a good handset antenna performance. Among the human body effect, the finger is of particular interest since it is usually placed over the antenna area which may cause detuning and/or reduction of the efficiency. To mitigate the finger loading effects, a novel handset antenna consisting of two small antennas distributed along the ground plane is proposed. The distributed antenna system is compared with a single antenna having a broadband matching network, so both designs feature enough bandwidth to cover the GSM850 (824-890MHz) and GSM900 (880-960MHz) communication systems. The finger effect is analyzed in terms of efficiency using a phantom hand. Efficiency is measured for different finger locations concluding that the distributed antenna system is more robust to the finger loading effect.

Title: White dwarf mergers and the origin of R coronae borealis stars Authors: Lorén Aguilar, Pablo; Longland, Richard Leigh; José Pont, Jordi; García-Berro Montilla, Enrique; Althaus, Leandro G.; Isern-Fontanet, J. Abstract: We present a nucleosynthesis study of the merger of a 0.4 M? helium white dwarf with a 0.8 M? carbon-oxygen white dwarf, coupling the thermodynamic history of Smoothed Particle Hydrodynamics particles with a post-processing code. The resulting chemical abundance pattern, particularly for oxygen and fluorine, is in qualitative agreement with the observed abundances in R Coronae Borealis stars.

Title: OSPF-TE extensions for green routing in optical networks Authors: Wang, Jiayuan; Ricciardi, Sergio; Manolova Vasileva, Anna; Ruepp, Sarah; Careglio, Davide; Dittmann, L. Abstract: This paper proposes extensions to the OSPF-TE protocol to enable green routing in GMPLS-controlled optical networks. Simulation results show a remarkable reduction in CO 2 emissions by preferring network elements powered by green energy sources in the connection routing.

Title: A novel condition monitoring scheme for bearing faults based on Curvilinear Component Analysis and hierarchical neural networks Authors: Delgado Prieto, Miquel; Cirrincione,, Giansalvo; García Espinosa, Antonio; Ortega Redondo, Juan Antonio; Henao, Humberto Abstract: Mostly the faults in electrical machines are related with the bearings. Thus, a reliable bearing condition monitoring scheme able to detect either local or distributed defects are mandatory to avoid a breakdown in the machine. So far, the research has been carried out mainly in the detection of local faults, such as balls and raceways faults, but surface roughness is not so reported. This paper deals with a novel and reliable scheme capable to detect any fault that may occur in a bearing, based on EXIN Curvilinear Component Analysis, CCA, and Neural Network. The EXIN CCA, which is an improvement of the Curvilinear Component Analysis, has been conceived for data visualization, interpretation and classification for real time industrial applications. The effectiveness of this condition monitoring scheme has been verified by experimental results obtained from different operation conditions.

Title: Transactional access to shared memory in StarSs, a task based programming model Authors: Gayatri, Rahulkumar; Badia Sala, Rosa Maria; Ayguadé Parra, Eduard; Lujan, M; Watson, I. Abstract: With an increase in the number of processors on a single chip, programming environments which facilitate the exploitation of par- allelism on multicore architectures have become a necessity. StarSs is a task-based programming model that enables a flexible and high level programming. Although task synchronization in StarSs is based on data flow and dependency analysis, some applications (e.g. reductions )require locks to access shared data. Transactional Memory is an alternative to lock-based synchronization for controlling access to shared data. In this paper we explore the idea of integrating a lightweight Software Transactional Memory (STM) library, TinySTM , into an implementation of StarSs (SMPSs). The SMPSs run- time and the compiler have been modified to include and use calls to the STM library. We evaluated this approach on four applications and observe better performance in applications with high lock contention.

Title: The next city: low density territories in the metropolitan area of Barcelona Authors: Sotoca García, Adolfo; Massuet, Maria Abstract: In 2010 the Metropolitan Territorial Plan of Barcelona (PTMB) was approved. The plan is conceived as a strategic tool where some more specific and detailed planning will be framed in the next future. Some of the themes and challenges the detailed planning will be addressed to are here for the first time considered, since the scale the plan covers has been never approached before. For the first time the low density developments in this territory are faced as a whole phenomenon that needs to be readdressed. The Plan defines the “Specialized Residential Areas to Restructure” (AERR) which are low density residential areas in the form of continuous large-scale urban settlements, usually placed on steep areas, where physical conditions are critical to residential uses. These areas will be subject to further planning committed with the improvement the basic living conditions of its physical environment. This paper announces the description of these strategic lines which were applied in form of analysis over the AERR. The goal of the research is to obtain some useful criteria for further renewal of low density territories in the metropolitan area of Barcelona.
