The BWN-II problem specification involved a broadly defined design and operation problem for an existing network that has to be upgraded for increased future demands, and the addition of a new development area. The design decisions involved addition of new and parallel pipes, storage, operational controls for pumps and valves, and sizing of backup power supply. Design criteria involved hydraulic, water quality, reliability, and environmental performance measures. Fourteen teams participated in the Battle and presented their results at the 14th Water Distribution Systems Analysis conference in Adelaide, Australia, September 2012. This paper summarizes the approaches used by the participants and the results they obtained. Given the complexity of the BWN-II problem and the innovative methods required to deal with the multiobjective, high dimensional and computationally demanding nature of the problem, this paper represents a snap-shot of state of the art methods for the design and operation of water distribution systems. A general finding of this paper is that there is benefit in using a combination of heuristic engineering experience and sophisticated optimization algorithms when tackling complex real-world water distribution system design problems.
- PublicationQuantitative approach to assist neuroblastoma assessment by measuring I-123 mIBG uptake in scintigraphic images(International Society for Stereology & Image Analysis, 2015) Martínez Díaz, Rafael; Balaguer Guill, Julia; Sánchez Ruiz, Luis Manuel; Bello Arques, Pilar; Castel, Victoria; Rivas Sanchez, Antonio; Cañete Nieto, Adela; Falgás Lacueva, Marina; Loaiza Gongora, Jose Luis; Peris Fajarnes, Guillermo; Dpto. de Matemática Aplicada; Dpto. de Ingeniería Gráfica; Escuela Técnica Superior de Ingeniería del Diseño; Escuela Técnica Superior de Ingeniería Geodésica, Cartográfica y Topográfica; Área de Sistemas de la Información y las Comunicaciones; Centro de Investigación en Tecnologías Gráficas; Hospital Universitari i Politècnic La Fe; Universitat Politècnica de ValènciaWhole-body 123I-Metaiodobenzylguanidine (mIBG) scintigraphy is used as the primary image modality in neuroblastoma detection. It is the most sensitive and specific method for staging and response evaluation. Validated semi-quantitative scoring methods with low interobserver variability and high reproducibility have shown to be indispensable for the evaluation of response to therapy. However, low resolution, noise and acquisition difficulties, specially in children, make low definition scans. These facts increase observer dependent interpretations that limit assessment and complicate to put a scoring method succesfully into practice. It is essential to have an objective and reliable measure of response to test the activity of therapies. In this paper we propose the use of a quantitative observer-independent measurement of the strength of uptake to be used as an additional tool for assisting the International Society of Paediatric Oncology Europe Neuroblastoma Group (SIOPEN) semi-quantitative scoring method. This is the scoring method recommended by the SIOPEN Nuclear Medicine and Physics Committee, in collaborative work with the Children’s Oncology Group, as the standard one for acquiring and reporting diagnostic paediatric mIBG scans across Europe. Our proposed method is based on the ratio between the amount of specific uptake at tumours and the amount of non-specific uptake at SIOPEN anatomical sectors which has shown to be constant in all the scans of the patients.

Con estos datos, hemos realizado 5 estudios (4 self-Benchmark de cada aeropuerto y 1 peer-benchmark de todos juntos). Por medio de la herramienta matemática MACBETH donde hemos incluido la opinión de los especialistas. El trabajo previo a la parte práctica es un análisis de 25 artículos y una descripción detallada de las palabras clave. Para concluir, sacamos conclusiones de los resultados y se proponen mejoras del estudio.
- PublicationObjective Evaluation of the Width of Source Ensemble in Virtual Halls(American Society of Mechanical Engineers (ASME), 2012-08) Cerdá Jordá, Salvador; Giménez Pérez, Maria Alicia; Cibrián Ortíz de Anda, Rosa; Segura Garcia, Jaume; Montell Serrano, Radha Empar; Barba Sevillano, Arturo; Dpto. de Física Aplicada; Dpto. de Matemática Aplicada; Área de Sistemas de la Información y las Comunicaciones; Escuela Técnica Superior de Ingeniería Industrial; Escuela Técnica Superior de Ingeniería Informática; Ministerio de Ciencia e Innovación; Ministerio de Ciencia y Tecnología[EN] In this work, we study the effects of the width of the sound source in several acoustical virtual room models with different topologies, sizes and uses, calibrated with commercial software. To achieve this aim, a square distribution of sound sources with variable side length has been considered. We have auralized four channels of speech signal and musical signal in three different locations in each room. By using signal processing techniques, a comparison of multisource auralizations with the ones obtained from a single source in the middle of the stage is made. Also, the variations between the usual room parameters obtained from these simulations are analyzed, in order to show the effect of the hall in the objective evaluation according to the source width.
- PublicationModelling with uncertainty the ideological evolution of a society with extreme groups(Universitat Politècnica de València, 2014-03-03T07:22:59Z) Tarazona Tornero, Ana Celia; Santonja Gómez, Francisco José; Villanueva Oller, Francisco Javier; Villanueva Micó, Rafael Jacinto; Facultad de Administración y Dirección de Empresas; Dpto. de Matemática Aplicada; Instituto Universitario de Matemática Multidisciplinar; Área de Sistemas de la Información y las ComunicacionesThe Basque Country is a northern Spanish region (Autonomous Community) where, from 1960¿s, there is a organization called ETA that wants to achieve its political goals by violent means. The Basque population is divided, mainly, into the ones who support or reject the ETA¿s political goals and its violent means. Also, the pressure of ETA and its supporters on the Basque population are present in the daily life. Taking into account the Basque scenario, in this PhD dissertation, we are interested in how the di¿erent groups of people defined by their attitude towards ETA evolve over the time, with two main aims: ¿ find out which the most relevant events that make changes in the attitude evolution are, ¿ taking into account the relation between ETA¿s supporters and ETA¿s member source, predict the attitude evolution in the next future in order to see if the supporters group wanes and, as a consequence, ETA also does. To do that, on one hand, we use elections and Euskobarometro data (Euskobaromero is a sociological statistical survey in the Basque Country), and then, we build the mathematical models assuming the hypothesis that the change of attitude, ideology or opinion may be socially transmitted. Therefore, classical techniques in epidemiology are used to build and study these models. On the other hand, we should not forget that we want to study a problem in Social Sciences, where data, coming from surveys, contain errors. Therefore, during the development of this dissertation it is necessary to use techniques to deal with uncertainty in the presented models. In fact, we use some, trying to avoid in each new technique the disadvantages that appear in the previous one. The structure of this PhD dissertation is as follows. In Chapter 1 we introduce the problem to be studied and make a historical overview of the PhD thesis. In Chapter 2 we summarise the main facts in the history of ETA that we consider relevant to the proper development of the present dissertation. A firstmodel is presented in Chapter 3. Here, we divide the population of the Basque Country depending on the political party they vote and classify the political parties respect to their opinion on the idea of ¿independence from Spain¿, one of the main goals of ETA. Thus, with data of general elections, we build a type-epidemiological model and use the Latin Hypercube Sampling technique to predict with uncertainty over the next election dates, the dynamics of the population respect to the idea of ¿independence from Spain¿. In the Chapter 4, Euskobarometro data about the ¿population attitude towards ETA¿ are used to build a model to find out if the ¿Law of Political Parties¿ (LPP) passed in Jun 2002 had e¿ect on the attitude towards ETA of the Basque Population. We use a bootstrapping technique to know if the di¿erences between the model prediction and Euskobarometro data after LPP are significative and quantify these di¿erences. In this case, bootstrapping is the technique that allows us to deal with the model uncertainty. In the Chapter 5, using the same model as in the Chapter 4 and Euskobarometro data about the population attitude towards ETA since May 2005, we predict with uncertainty the evolution dynamics of the groups providing a model confidence band prediction over the next few years. To do that we introduce a new computational technique to deal with the model uncertainty.
- PublicationPsychoacoustic parameters as a tool for subjective assessment in catering premises(Science and Engineering Publishing Company, USA, 2013) Segura Garcia, Jaume; Cerdá Jordá, Salvador; Montell Serrano, Radha Empar; Romero Faus, José; Cibrián Ortíz de Anda, Rosa; Giménez Pérez, Maria Alicia; Dpto. de Física Aplicada; Dpto. de Matemática Aplicada; Área de Sistemas de la Información y las Comunicaciones; Escuela Técnica Superior de Ingeniería Industrial; Escuela Técnica Superior de Ingeniería Informática; Ministerio de Ciencia e Innovación; Universitat de València[EN] Psycho-acoustic perception of an environment is an important factor in the assessment and subjective description of the soundscape. It determines the environmental impact on each of the individuals. The parameters associated with these models allow us to determine ratings of nuisance in each environment in order to make comparisons. In this paper, a description of various parameters of sound quality (loudness, sharpness, roughness, fluctuation strength and tonality) is made to assess the nuisance / pleasure models by Zwicker. A comparison with different kinds of restaurants is also made. The models involved are influenced by the acoustics of the premises.
