Waste Map of the province of Castellón

Ponencia presentada en el XV Congreso Internacional de Ingeniería de Proyectos celebrado en Huesca, 6-8 de julio de 2011The problem of the ever-increasing generation of waste becomes more acute with inadequate environmental management, leads to environmental problems and highlights the ineffectiveness of society when using its resources. This paper presents a study to assess the current situation of generation and management of waste in the province of Castellon (Spain). The study involves the creation of an inventory of waste produced in each municipality in the province, including different waste categories and their breakdown by fractions. The destination of the different types of waste and the treatments applied to them are also determined. A Geographic Information System (GIS) is used to carry out this study. This enables the integration of spatial and alphanumeric information related to both the sources of waste generation and waste treatment facilities. The GIS enables geographical representation of the data collected on thematic maps, and provides tools for spatial analysis of these data. Spatial analysis is useful for locating problems in waste management and proposing strategies to improve the present situation. Finally, a web map viewer is developed in order to disseminate the results. The web viewer provides access to the digital maps on waste obtained from the study

Control de vuelo para seguimiento de trayectorias de un cuadricóptero simulado mediante ROS/Gazebo

Los cuadricópteros son uno de los robots aéreos más usados a día de hoy, más comúnmente conocidos como drones. A causa de esto, la investigación y desarrollo de sus tecnologías está en continuo crecimiento con el objetivo de conseguir vuelos cada vez más autónomos. Al tratarse de tecnologías de un elevado coste económico, en los primeros pasos de las investigaciones se hace uso de simuladores. Esta alternativa, además de suponer una ventaja a nivel económico, permite una experimentación más rápida y segura. Gazebo es uno de los simuladores más usados en el ámbito de la investigación robótica y el elegido para este proyecto. Para hacer posible su funcionamiento debe usarse ROS (Robot Operating System), cuya unidad fundamental son los nodos. Son sus ejecutables y se organizan en paquetes. A lo largo del trabajo se ha comprobado el potencial de su uso conjunto y con otros software muy usados en el ámbito de la ingeniería como Matlab.El objetivo de este proyecto es el control del vuelo de un cuadricóptero simulado siguiendo una trayectoria planificada. Para ello se han usado paquetes de ROS, hector quadrotor, que modelan el comportamiento de un dron genérico y su simulación. Para el control se ha desarrollado un módulo al que se supone la llegada externa de puntos planificados con una determinada separación temporal que constituyen la trayectoria. Un algoritmo calcula la velocidad a tomar por el dron en función de su posición y la planificación con una cierta periodicidad. Esta velocidad es comunicada al modelado del dron, quien efectúa los movimientos pertinentes.Las simulaciones llevadas a cabo comprueban el correcto funcionamiento del controlador implementado. El dron alcanza los objetivos en los tiempos esperados con movimientos suaves y controlados. Además con ellas se han establecido las características que han de tener los puntos planificados para que así sea. Tanto los resultados como el análisis previo de las funcionalidades del entorno de simulación pueden usarse en proyectos futuros con este mismo tipo de aeronaves.<br /

Vehicle Classification in Traffic Environments Using the Growing Neural Gas

Traffic monitoring is one of the most popular applications of automated video surveillance. Classification of the vehicles into types is important in order to provide the human traffic controllers with updated information about the characteristics of the traffic flow, which facilitates their decision making process. In this work, a video surveillance system is proposed to carry out such classification. First of all, a feature extraction process is carried out to obtain the most significant features of the detected vehicles. After that, a set of Growing Neural Gas neural networks is employed to determine their types. A qualitative and quantitative assessment of the proposal is carried out on a set of benchmark traffic video sequences, with favorable results.Universidad de Málaga.

The begomovirus Tomato leaf curl New Delhi virus is not seed-transmitted in melon

Transmission of plant viruses through seed can be one of the major factors contributing to long- distance dispersal through global trade of seeds and can have important ecological consequences for virus dissemination. Begomoviruses (genus Begomovirus, family Geminiviridae), and among them isolates of the species Tomato leaf curl New Delhi virus (ToLCNDV), cause significant yield losses in economically important crops worldwide. These viruses are horizontally transmitted in nature in a circulative and persistent manner by the whitefly Bemisia tabaci but in recent years several reports have raised the possibility of vertical transmission through seeds for some members of this genus. We have investigated the possible transmission by melon (Cucumis melo L.) seeds of a ToLCNDV isolate of the “Spain” strain, in three different melon cultivars (all susceptible to ToLCNDV). The presence of ToLCNDV in floral tissues and the detection of viral DNA in seeds reveals the seed-borne nature of this virus. However, grow-out studies conducted with the progeny of melon plants germinated from seeds collected from ToLCNDV-infected plants and evaluated at early (1 leaf) or at late (20 leaves) growth stages did not support the vertical transmission of ToLCNDV from seeds to the offspring.Universidad de Málaga.

Storm Gloria: sea state evolution based on in situ measurements and modeled data and its impact on extreme values

Storm Gloria, generated on January 17th, 2020 in the Eastern North Atlantic, crossed the Iberian Peninsula and impacted the Western Mediterranean during the following days. The event produced relevant damages on the coast and the infrastructures at the Catalan-Balearic Sea, due to extraordinary wind and wave fields, concomitant with anomalously intense rain and ocean currents. Puertos del Estado (the Spanish holding of harbors) has developed and operates a complex monitoring and forecasting system (PORTUS System), in collaboration with the Spanish Met Office (AEMET). The present work shows how Gloria was correctly forecasted by this system, alerts were properly issued (with special focus to the ports), and the buoys were able to monitor the sea state conditions during the event, measuring several new records of significant wave height and exceptional high mean wave periods. The paper describes, in detail, the dynamic evolution of the atmospheric conditions, and the sea state during the storm. It is by means of the study of both in situ and modeled PORTUS data, in combination with the AEMET weather forecast system results. The analysis also serves to place this storm in a historical context, showing the exceptional nature of the event, and to identify the specific reasons why its impact was particularly severe. The work also demonstrates the relevance of the PORTUS System to warn, in advance, the main Spanish Ports. It prevents accidents that could result in fatal casualties. To do so, the wave forecast warning performance is analyzed, making special focus on the skill score for the different horizons. Furthermore, it is demonstrated how a storm of this nature results in the need of changes on the extreme wave analysis for the area. It impacts all sorts of design activities at the coastline. The paper studies both how this storm fits into existing extreme analysis and how these should be modified in the light of this particular single event. This work is the first of a series of papers to be published on this issue. They analyze, in detail, other aspects of the event, including evolution of sea level and description of coastal damages

El impacto de la responsabilidad social empresarial en la gestión empresarial: algunas evidencias empíricas en pequeñas y medianas empresas españolas

The principal aim of this work has been to study the relevancy of what is known as social managerial or corporate responsibility (RSE), how this new philosophy strikes on the business management and to check in that degree the small and medium Spanish companies are taking up office or practising this new beginning of management and the motives that they stimulate. For it, there was realized an empirical study centred on the analysis of which they would be the conceptions and the basic reasons that handle the businessmen-managers and his influence in the promotion of internal and external actions of RSE. There was in use as procedure of obtaining of information a survey applied to a sample of 122 businessmen/managers belonging to small and medium companies. The results tend to reveal that the actions or practices of responsibility social of more strategic or advanced character are motivated by the possibility of obtaining helps or fiscal benefits, whereas the most philanthropic or traditional measures of the RSE would answer to criteria or reasons of improving the relations with the groups of interest or stakeholders as clients and workers.El principal objetivo de este trabajo ha sido estudiar la relevancia de lo que se conoce como responsabilidad social empresarial o corporativa (RSE), cómo esta nueva filosofía impacta sobre la gestión empresarial y verificar en qué grado las pequeñas y medianas empresas españolas están asumiendo o practicando estos nuevos principios de gestión y los motivos que las impulsan. Para ello, se realizó un estudio empírico centrado en el análisis de cuáles serían las concepciones y las razones básicas que manejan los empresarios/gerentes y su influencia en la promoción de acciones internas y externas de RSE. Se utilizó como procedimiento de obtención de datos una encuesta aplicada a una muestra de 122 empresarios/gerentes pertenecientes a pequeñas y medianas empresas. Los resultados tienden a revelar que las acciones o prácticas de responsabilidad social de carácter más estratégico o avanzado están motivadas por la posibilidad de obtener ayudas o beneficios fiscales, mientras que las medidas más filantrópicas o tradicionales de la RSE responderían a criterios o razones de mejorar las relaciones con los grupos de interés o stakeholders como clientes y trabajadores

Value Of [f-18]fdg-pet/ct and Ca125, serum levels and kinetic parameters, in early detection of ovarian cancer recurrence. Influence of histological subtypes and tumor stages

To assess the diagnostic accuracy of CA125, its kinetic values and positron emission tomography/computed tomography with 2-deoxy-2-[F-18]fluoro-d-glucose ([F-18]FDG-PET/CT), in relation with tumor characteristics for suspected recurrence of ovarian cancer. To evaluate the performance of CA125-related parameters as a selection criteria to perform a [F-18]FDG-PET/CT.A retrospective analysis of 69 [F-18]FDG-PET/CT for suspected recurrence of ovarian cancer was performed. All patients had 2 measurements of CA125, before PET/CT, to calculate kinetic values, as CA125vel (CA125vel = [CA125a - CA125b]/time) and CA125dt (CA125dt = [log(2) x time]/[logCA125a - CA125b]). Maximum standard uptake value (SUVmax) was calculated. The diagnostic accuracy was calculated for all the variables and the optimal cut-off value of each of them by the receiver-operating characteristics (ROC) analysis. All the tests were compared with tumor characteristics and clinical-radiological evolution during follow-up of at least 6 months.Fifty-five cases were diagnosed of recurrence (11 with CA125<35 U/mL), while 14 showed no disease (11 with CA125< 35 U/mL). All of them were correctly cataloged by PET/CT. CA125, CA125vel, and SUVmax showed higher levels in recurrent patients (mean 129.54U/mL, 24.58U/mL per mo, and 8.69g/mL, respectively) than in nonrecurrent (mean 20.35U/mL, 0.60U/mL per mo, and 0.64g/mL, respectively). No statistical differences in CA125dt were found. Patients with recurrence of high-grade serous carcinoma (HGSC) showed higher CA125 and CA125vel, without differences in the rest of subtypes and International Federation of Gynecology and Obstetrics stages. The ROC analyses for CA125, CA125vel, and CA125dt showed an area under the curve (AUC) of 0.873 (95% confidence interval [CI] 0.77-0.969), 0.903 (95% CI 0.813-0.994), and 0.727 (95% CI 0.542-0.913), respectively, with an optimal cut-off point of 23.95U/mL, 4.49U/mL per mo, and 3.36 months, respectively, while for the SUVmax the AUC was of 0.982 (95% CI 0.948-1.000), and the cut-off point of 2. Multivariate regression analysis identified CA125 and CA125vel as predictors of recurrence.[F-18]FDG-PET/CT is more accurate than the parameters obtained from the CA125 to detect early recurrence. CA125vel is the most suitable parameter, mainly in HGSC. Levels of CA125vel 4.49U/mL per mo facilitate earlier detection by the execution of a [F-18]FDG-PET/CT. The calculation of these parameters is independent of tumor stage at diagnosis
