Wersync: A WEB-BASED PLATFORM FOR DISTRIBUTED MEDIA SYNCHRONIZATION AND SOCIAL INTERACTION

This paper presents Wersync, which is an adaptive and accurate web-based platform that enables distributed media synchronization and social interaction across remote users. By using Wersync, users can create or join on-going sessions for concurrently consuming the same media content with other remote users in a synchronized manner. Besides, social interaction is provided by sharing the navigation control commands and by integrating synchronized text chat channels. Additionally, two social presence mechanisms have been added to stimulate the participation of external users in on-going sessions on Wersync. By exclusively relying on standard web-based technologies, this platform can guarantee cross-network, cross-platform and crossdevice support, which is a key point in the current heterogeneous media delivery ecosystem

Persistent traffic offenders. Alcohol consumption and personality as predictors of driving disqualification

This paper explores the relevance of alcohol consumption and personality factors as predictors of driving disqualification. The aim of the study is to determine whether the behaviors of persistent offenders and their propensity for law-breaking are related to their characteristics and patterns of drinking. A sample of 358 drivers participated in the study: 126 non-offender habitual drivers, and 232 persistent traffic offenders disqualified from driving for serious or repeated traffic offenses, 127 of them after conviction, 105 without conviction (by accumulation of penalties). Participants were given a battery of tests measuring a set of explanatory personality and alcohol consumption factors. We used a cross-sectional study design and performed statistical analysis of variance and regression searching for differences among the groups. The results reveal group effects, with significant differences between traffic offenders and non-offenders, and between both categories of offenders, in a number of variables, including traffic violations that lead to demerit points and/or loss of a driver's license and crash involvement. Certain variables, including problem drinking, high levels of activity or excitement, penchant for thrill or sensation seeking, and propensity to hostility while driving, can accurately predict group membership. Alcohol disorders are the best predictors of disqualification from driving

Evaluating dolphin damage in trammel net fisheries in the Valencia region: Insights to improve management

[EN] Interactions between dolphins and trammel net fisheries have been described in the Mediterranean Sea as having negative consequences for both cetaceans and fishers. There is a need for studies that evaluate the economic costs caused by dolphins feeding from entangled fishes in trammel nets since most cetacean species involved in these interactions are endangered. This study aims to evaluate the economic impact of the interaction between dolphins and trammel nets fisheries in the coastal waters of the Valencian region in the western Mediterranean Sea. We conducted at-port visual inspections of nets from April 2018 to March 2019, which included 1,849 fishing operations with trammel nets, and we recorded damages to the net and catch and the value of the fishery. Thirty-two interactions were detected during the year of the study. The only observed species interacting was the common bottlenose dolphin. No bycatch of dolphins was reported. The interactions have been impacted seasonally and most of them took place in February and March. There were no significant differences in catch when comparing sets with and without depredation or damage in nets due to depredation by dolphins. Also on average, no differences were found in the value of the catch when comparing sets with or without damage caused by dolphins. The main cost to the fisher was the cost of repairing the nets. The estimated financial loss per vessel and year was €556 (95%CI: €303¿€809). This represents less than 1% of the total yearly income of each vessel in our area. We suggest implementing tools to economically compensate artisanal vessels for any damage caused by dolphins in order to avoid increasing the hostile feeling of fishers towards dolphins and to apply conservation measures to protect this cetacean species.Feliu-Tena, B.; Rodilla, M.; Pastor Gimeno, JI.; Abalo-Morla, S.; Bou-Cabo, M.; Belda, E.

Conducting Polymer–TiO2 Hybrid Materials: Application in the Removal of Nitrates from Water

Materials able to produce the reduction of nitrate from water without the need of a metal catalyst and with avoiding the use of gaseous hydrogen have been developed by combining the synergistic properties of titania and two conducting polymers. Polymerization of aniline and pyrrol on titanium dioxide in the presence of two different oxidants/dopants (iron trichloride or potassium persulfate) has been evaluated. The resulting hybrid materials have good thermal stability imparted by the titania counterpart, and a considerable conductivity provided by the conducting polymers. The capability of the hybrid materials of reducing aqueous nitrate has been assessed and compared to the catalytic hydrogenation of nitrate using a platinum catalyst supported on these hybrid synthesized materials. The mechanism of nitrate abatement implies adsorption of nitrate on the polymer by ion exchange with the dopant anion, followed by the reduction of nitrate. The electron transfer from titania to the conducting polymer in the hybrid material favors the reductive ability of the polymer, in such a way that nitrate is selectively reduced with a very low production of undesirable side products. The obtained results show that the activity and selectivity of the catalytic reduction of nitrate with dihydrogen in the presence of a platinum catalyst supported on the hybrid materials are considerably lower than those of the metal-free nanocomposites.Financial support from Generalitat Valenciana, Spain (PROMETEOII/2014/004) and Ministry of Economy and Competitivity (MAT2016-80285-P) is gratefully acknowledged.

Aprendizaje Basado en Proyectos en asignaturas de Ciclo de Vida del Producto en estudios de Máster de Diseño y Fabricación

[EN] The goal of this educational innovation is to introduce the Project-Based Learning (PBL) methodology in the first course of the University Master's Degree in Computer-Assisted Integrated Manufacturing and Design of the Polytechnic University of Valencia (Spain), which is considered a strategy of effective teaching for the acquisition of knowledge and skills that society is demanding from students. By applying this methodology, students are able to plan, implement and evaluate projects that have applications in the real world and that go beyond the mere presentation of knowledge by the teacher, very common in master classes. This innovation has aimed to develop related competencies, not only with teamwork, but also with skills and strategies for management, location, search and evaluation of information from electronic sources and management of specialized software. Although the PBL is a difficult methodology to apply in certain areas of Higher Education, the results obtained highlight the advantages that this type of methodology offers in subjects related to Design and Manufacturing Engineering, such as an optimal interaction between teachers and students or the creation of a positive learning environment in the classroom allowing a better teaching and learning process.[ES] El objetivo de esta innovación docente ha sido introducir en el primer curso del Máster Universitario en Diseño y Fabricación Integrada Asistida por Ordenador de la Universitat Politècnica de València la metodología de Aprendizaje Basado en Proyectos (ABP), la cual se considera una estrategia de enseñanza eficaz para la adquisición de los conocimientos y competencias que la sociedad demanda a los estudiantes. Al aplicar esta metodología los estudiantes planifican, implementan y evalúan proyectos que tienen aplicaciones en el mundo real y que van más allá de la mera exposición de conocimientos por parte del profesor. Esta innovación ha tenido como meta desarrollar competencias relacionadas, no solo con el trabajo en equipo, sino también con habilidades y estrategias de gestión, búsqueda y evaluación de información a partir de fuentes documentales electrónicas y manejo de software especializado. Aunque el ABP es una metodología difícil de aplicar en ciertas áreas de la Educación Universitaria, los resultados obtenidos resaltan las ventajas que ofrece este tipo de metodología en asignaturas relacionadas con la Ingeniería de Diseño y Fabricación como, por ejemplo una mejor interacción entre profesores y estudiantes o la creación de un ambiente positivo de aprendizaje en el aula.Feito Sánchez, N.; Belda González, R.; Megías Díaz, R.; Vila Pastor, C.

Effect of cold Ar plasma treatment on the catalytic performance of Pt/CeO2 in water-gas shift reaction (WGS)

The effect of Ar plasma treatment on the catalytic performance of Pt/CeO2 has been studied. The catalyst was activated using different procedures separately or in combination: calcination, reduction under pure H2 and cold Ar plasma treatment. The resulting materials were characterized by X-ray photoelectron spectroscopy, X-ray adsorption near edge structure and temperature-programmed reduction with H2. The resulting materials were tested in the water-gas shift reaction (WGS). It has been found that the combination of calcination, plasma and hydrogen treatments leads to a very active catalyst for WGS. Furthermore, the catalyst structure–performance relationship has been assessed. The plasma treatment generated electron-enriched Pt particles which show a very strong interaction with the ceria support. This favoured CO chemisorption and increased the reducibility of the support, which takes part in the WGS the reaction by favouring water splitting.Financial support from Generalitat Valenciana (project PROMETEOII/2014/004) and MINECO (Project MAT2013-45008-P) is gratefully acknowledged.
