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: 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: 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: Real-time multimedia monitoring in large-scale wireless multimedia sensor networks: research challenges Authors: Cesana, Matteo; Redondi, Alessandro; Tiglao, Nestor; Grilo, Antonio; Barceló Ordinas, José María; Alaei, Mohammad; Todorova, Petia Abstract: Wireless Sensor Networks (WSNs) have enjoyed dramatic developments over the last decade. The availability of CMOS cameras and microphones enlarged the scope of WSNs paving the way to the development of Wireless Multimedia Sensor Networks (WMSN). Among the envisaged WMSN applications, Real-time Multimedia Monitoring constitutes one of the most promising. However, the resource requirements of these applications place difficult challenges in terms of network lifetime and scalability. This paper starts by identifying the main characteristics and requirements of Real-time Multimedia Monitoring applications and then highlights key research directions that may help to overcome those challenges.

Title: A two-dimensional architecture for end-to-end resource management in virtual network environments Authors: Wang, Ning; Zhang, Yi; Serrat Fernández, Juan; Gorricho Moreno, Juan Luis; Guo, Tao; Hu, Zheng; Zhang, Ping Abstract: In recent years, various network virtualization techniques have been proposed for flexibly supporting heterogeneous services over virtual network platforms. However, systematic views on how virtual network resources (VNRs) can be practically managed in such open environments has been missing till now. To fill the gap, we present in this article a two-dimensional architecture for end-to-end VNR management from distinct viewpoints of service providers and network providers. The horizontal dimension of VNR management allows SPs to bind VNRs rented from heterogeneous NPs to form unified end-to-end service delivery platforms. The vertical dimension of VNR management enables NPs to perform cost-efficient allocation of VNRs to requesting SPs, but without necessarily forcing themselves to collaborate with each other. Such a VNR management architecture will complement existing network virtualization platforms in accelerating the realization of virtual resource sharing in the future Internet business marketplaces.

Title: REMS: the environmental sensor suite for the Mars Science Laboratory rover Authors: Gómez Elvira, J.; Armiens, C.; Castañer Muñoz, Luis María; Domínguez Pumar, Manuel; Genzer, M.; Gómez, Francisco; Haberle, Robert M.; Harris, Aiden M.; Jimenez Serres, Vicente; Kahanpää, H.; Kowalski, Lukasz; Lepinette, A.; Martín, Jacques Wesley; Martínez Frías, Jesús; McEwan, I.; Mora, L.; Moreno, Jose C.; Navarro, S.; De Pablo, M.A.; Peinado, V.; Peña, A.; Polkko, J.; Ramos, Miguel; Renno, Nilton O.; Ricart, Jordi; Richardson, M.; Rodríguez Manfredi, José Antonio; Romeral, Julio; Sebastián, Eduardo M.; Serrano, Jaime; De La Torre Juárez, Manuel; Torres, Jose Antonio; Torrero, F.; Urquí, R.; Vázquez, L.; Velasco, T.; Verdasca, J.; Zorzano, M.P.; Martín Torres, Javier Abstract: The Rover Environmental Monitoring Station (REMS) will investigate environ- mental factors directly tied to current habitability at the Martian surface during the Mars Sci- ence Laboratory (MSL) mission. Three major habitability factors are addressed by REMS: the thermal environment, ultraviolet irradiation, and water cycling. The thermal environment is determined by a mixture of processes, chief amongst these being the meteorological. Ac- cordingly, the REMS sensors have been designed to record air and ground temperatures, pressure, relative humidity, wind speed in the horizontal and vertical directions, as well as ultraviolet radiation in different bands. These sensors are distributed over the rover in four places: two booms located on the MSL Remote Sensing Mast, the ultraviolet sensor on the rover deck, and the pressure sensor inside the rover body. Typical daily REMS observa- tions will collect 180 minutes of data from all sensors simultaneously (arranged in 5 minute hourly samples plus 60 additional minutes taken at times to be decided during the course of the mission). REMS will add significantly to the environmental record collected by prior missions through the range of simultaneous observations including water vapor; the ability to take measurements routinely through the night; the intended minimum of one Martian year of observations; and the first measurement of surface UV irradiation. In this paper, we describe the scientific potential of REMS measurements and describe in detail the sensors that constitute REMS and the calibration procedures

Title: Exponentiated Weibull model for the irradiance probability density function of a laser beam propagating through atmospheric turbulence Authors: Barrios, R.; Dios Otín, Víctor Federico Abstract: Many distributions have been proposed to model the probability density function of irradiance fluctuations. The most widespread models nowadays are the Lognormal (LN) and Gamma–Gamma (GG) distributions. Albeit these models comply with the actual PDF data most of the time, neither of them works in all scenarios and, depending on the conditions, one of the two have to be chosen. In this paper, a new model is presented resulting in the exponentiated Weibull (EW) distribution, along with a physical justification for the appearance of the model. Previously published data are used to compare the new model with the LN and GG distributions. Results suggest that the EW distribution is the better fit for data under all aperture averaging conditions and weak-to-strong turbulence regime.

Title: A taxonomy and survey of SCTP research Authors: Budzisz, Lukasz; Garcia, Johan; Brunstrom, Anna; Ferrús Ferré, Ramón Antonio Abstract: The Stream Control Transmission Protocol (SCTP) is a relatively recent general-purpose transport layer protocol for IP networks that has been introduced as a complement to the well-established TCP and UDP transport protocols. Although initially conceived for the transport of PSTN signaling messages over IP networks, the introduction of key features in SCTP, such as multihoming and multistreaming, has spurred considerable research interest surrounding SCTP and its applicability to different networking scenarios. This article aims to provide a detailed survey of one of these new features—multihoming—which, as it is shown, is the subject of evaluation in more than half of all published SCTP-related articles. To this end, the article first summarizes and organizes SCTP-related research conducted so far by developing a four-dimensional taxonomy reflecting the (1) protocol feature examined, (2) application area, (3) network environment, and (4) study approach. Over 430 SCTP-related publications have been analyzed and classified according to the proposed taxonomy. As a result, a clear perspective on this research area in the decade since the first protocol standardization in 2000 is given, covering both current and future research trends. On continuation, a detailed survey of the SCTP multihoming feature is provided, examining possible applications of multihoming, such as robustness, handover support, and loadsharing.

Title: JPSearch: new international standard providing interoperable framework for image search and sharing Authors: Yoon, Kyoungro; Kim, Youngseop; Park, Je-Ho; Delgado Mercè, Jaime; Yamada, Akio; Dufaux, Frederic; Tous Liesa, Rubén Abstract: For the last 15 years, there have been various research and great advances in the field of content-based search and retrieval of images. In this paper, we present an overview of the JPSearch Standard, which is a recently published set of international standards providing interoperable framework for image search and sharing. The JPSearch standard is composed of six parts, which are Part 1: System framework and components, Part 2: Registration, identification and management of schema and ontology, Part 3: Query format, Part 4: File format for metadata embedded in image data (JPEG and JPEG 2000), Part 5: Data interchange format between image repositories, Part 6: Reference software. The Part 1 provides motivation and overview of the JPSearch framework. The Part 2 supports interoperability among various metadata specifications and social tagging using the specification of core metadata and translation rule description language. The Part 3 provides powerful image query language for interoperability among multiple image databases. The Part 4 specifies a file format based on JPEG and JPEG 2000 file format in which arbitrary number of metadata description of a image can be embedded. The Part 5 supports interoperability in interchanging images with metadata between image repositories. Finally, the Part 6 provides reference and utility softwares based on which the JPSearch compliant systems can be easily developed. In this paper, summaries and usage examples for each part of the JPSearch standard are presented.
