Selección de un sistema de desinfección en proyectos de reutilización de las aguas residuales tratadas

[EN] Economic development often involves the need for additional water resources to carry out the new industrial or agricultural activities, or to supply the domestic, tourist and leisure activities demand. Moreover, this development usually leads to increased in population, which further increases the demand for water. In many places with arid or semiarid climate, this water scarcity leads to decreased water quality, even in areas with rainfall, the accumulation of demand in time and in space causes deficits, and produces social impact about the destination of available resources and damages to the environment. The reclaimed wastewaters are an unconventional source of water that has developed in recent decades. However, in order to reuse this resource, very important because of the quantity and the availability, appropriate technologies are required, specially an efficient disinfection system. This doctoral thesis presents an application of the Analytic Hierarchy Process (AHP) by integrating a Delphi process and combined with the VIKOR technique for selecting the best disinfection technology for treated wastewater reuse projects. The proposed methodology provides project managers a tool to evaluate problems with multiple criteria and multiple alternatives which involve non-commeasurable decision criteria, with expert opinions play playing a major role in the selection of these treatment alternatives. The alternatives have been evaluated for each of the criteria weighted according to the opinions of the experts consulted. Finally, the VIKOR method has been applied to determine a compromise solution, and to establish the stability of the results. Therefore, the expert system proposed to select the optimal disinfection alternative is a hybrid method combining the AHP with the Delphi method and the VIKOR technique, which is shown to be appropriate in realistic scenarios where multiple stakeholders are involved in the selection of a sustainable disinfection technique for wastewater reuse projects.[ES] El desarrollo económico suele implicar la necesidad de disponer de recursos hídricos adicionales para poder llevar a cabo las nuevas actividades industriales o agrícolas, o para abastecer la demanda correspondiente a las actividades domésticas, turísticas y de ocio. Además, este desarrollo conlleva habitualmente un aumento de población, lo que aún incrementa más la demanda de agua. En muchos lugares de clima árido o semiárido esta escasez de recursos hídricos ocasiona una disminución de la calidad del agua, incluso en lugares con lluvia suficiente la acumulación de la demanda en el tiempo y en el espacio crea deficiencias, y genera repercusiones sociales al respecto del destino de los recursos disponibles y su afectación al medio ambiente. Las aguas residuales regeneradas constituyen un recurso no convencional de agua que ha venido desarrollándose en los últimos decenios. No obstante, para poder proceder a reutilizar este recurso, de gran importancia por su volumen y disponibilidad, se requieren las tecnologías adecuadas y en particular unos sistemas de desinfección eficientes. Esta tesis presenta una aplicación del Proceso Analítico Jerárquico (AHP) mediante la integración de un proceso Delphi y combinado con la técnica VIKOR, para la selección de la mejor tecnología de desinfección en proyectos de reutilización y regeneración de aguas residuales tratadas. La metodología propuesta proporciona a los administradores de proyectos una herramienta para evaluar problemas con criterios múltiples y múltiples alternativas que implican criterios de decisión no cuantificables, con opiniones de expertos que juegan un papel importante en la selección de estas alternativas de tratamiento. Las alternativas han sido evaluadas para cada uno de los criterios, ponderados de acuerdo a las opiniones de los expertos consultados. Finalmente, se aplica el método VIKOR para determinar una solución de compromiso, y establecer la estabilidad de los resultados. Por tanto, el sistema experto propuesto para seleccionar la alternativa óptima de desinfección es un método híbrido que combina el procedimiento AHP con el método Delphi y la técnica VIKOR, y se muestra apropiado en escenarios realistas donde múltiples actores están involucrados en la selección de una técnica de desinfección sostenible en proyectos de regeneración de aguas residuales tratadas.[CA] El desenvolupament econòmic sol implicar la necessitat de disposar de recursos hídrics addicionals per a poder dur a terme les noves activitats industrials o agrícoles, o per a abastir la demanda corresponent a les activitats domèstiques, turístiques i d'oci. A més, aquest desenvolupament comporta habitualment un augment de població, la qual cosa encara incrementa més la demanda d'aigua. En molts llocs de clima àrid o semi àrid esta escassetat de recursos hídrics ocasiona una disminució de la qualitat de l'aigua, fins i tot en llocs amb pluja suficient l'acumulació de la demanda en el temps i en l'espai crega deficiències, i genera repercussions socials respecte d'això del destí dels recursos disponibles i la seua afectació al medi ambient. Les aigües residuals regenerades constituïxen un recurs no convencional d'aigua que ha vingut desenvolupant¿se en els últims decennis. No obstant això, per a poder procedir a reutilitzar aquest recurs, de gran importància pel seu volum i disponibilitat, es requerixen les tecnologies adequades i en particular uns sistemes de desinfecció eficients.

Finalment, s'aplica el mètode VIKOR per a determinar una solució de compromís, i establir l'estabilitat dels resultats. Per tant, el sistema expert proposat per a seleccionar l'alternativa òptima de desinfecció és un mètode híbrid que combina el procediment AHP amb el mètode Delphi i la tècnica VIKOR, i es mostra apropiat en escenaris realistes on múltiples actors estan involucrats en la selecció d'una tècnica de desinfecció sostenible en projectes de regeneració d'aigües residuals tractades.Cuenca Ruiz, MA.

Sentiment Analysis of Twitter in Tourism Destinations

[EN] Given the importance of electronic word of mouth (eWOM), this paper analyses the content of messages generated by users related to a tourist destination and shared through Twitter. We propose three research questions regarding eWOM behaviour in Twitter focused on the expertise of the reviewer, sentiment analysis of a tweet and its content.In order to address those research questions we carry out text mining analysis by retrieving existing information on Twitter (over 1500 tweets) regarding to Venice as a tourist destination.Authors acknowledge financial support of research project UV-INV_AE19-1212255.Perez Cabañero, C.; Bigne, E.; Ruiz Mafe, C.; Cuenca, AC.

Are customer star ratings and sentiments aligned? A deep learning study of the customer service experience in tourism destinations

This study explores the consistency between star ratings and sentiments expressed in online reviews and how they relate to the different components of the customer experience. We combine deep learning applied to natural language processing, machine learning and artificial neural networks to identify how the positive and negative components of 20,954 online reviews posted on TripAdvisor about tourism attractions in Venice impact on their overall polarity and star ratings. Our findings showed that sentiment valence is aligned with star ratings. A cancel-out effect operates between the positive and negative sentiments linked to the service experience dimensions in mixed-neutral reviews

Selecting a sustainable disinfection technique for wastewater reuse projects

[EN] This paper presents an application of the Analytical Hierarchy Process (AHP) by integrating a Delphi process for selecting the best sustainable disinfection technique for wastewater reuse projects. The proposed methodology provides project managers a tool to evaluate problems with multiple criteria and multiple alternatives which involve non-commeasurable decision criteria, with expert opinions playing a major role in the selection of these treatment technologies. Five disinfection techniques for wastewater reuse have been evaluated for each of the nine criteria weighted according to the opinions of consulted experts. Finally, the VIKOR method has been applied to determine a compromise solution, and to establish the stability of the results. Therefore, the expert system proposed to select the optimal disinfection alternative is a hybrid method combining the AHP with the Delphi method and the VIKOR technique, which is shown to be appropriate in realistic scenarios where multiple stakeholders are involved in the selection of a sustainable disinfection technique for wastewater reuse projects.Curiel-Esparza, J.; Cuenca-Ruiz, MA.; Martín Utrillas, MG.; Cantó Perelló, J.

Innovation, Creativity and Entreprenaeurship Learning Outcomes in Higher Education

A major trend in higher education is the current shift towards improving students’ creativity and individual thinking. The aim of this shift is to bring students closer to the real world and the complex problems they will encounter outside formal education. Competencies describe what training participants should be able to do at the end of such training. This paper defines the learning outcomes associated with the innovation, creativity and entrepreneurship competency. This proposal draws on a review of the innovation and competencies literature and the expertise of selected staff. According to the literature review and the following analysis by the authors, the main indicators (key aspects) associated with the competency are as follows: seek opportunities, generate ideas, execute plans and add value. These indicators vary by educational level to reflect increasing complexity and difficulty in the learning outcomes at each stage of university education. This paper proposes learning outcomes and indicators associated with the competencies of innovation, creativity and entrepreneurship. It corresponds to the first essential step associated with the definition of a competency assessment.This research has been partially supported by: Project for educational improvement B019/14.

What drives the helpfulness of online reviews? A deep learning study of sentiment analysis, pictorial content and reviewer expertise for mature destinations

Los destinos turísticos se ven cada vez más afectados por la información relacionada con los viajes que se comparte a través de las redes sociales. Basándose en teorías de proceso dual sobre cómo los individuos procesan la información, este estudio examina el papel de las rutas de procesamiento de información central y periférica en la formación de las percepciones de los consumidores sobre la utilidad de las reseñas en línea de destinos maduros. Llevamos a cabo un proceso de dos pasos para abordar la utilidad percibida del contenido generado por el usuario, un análisis de sentimiento utilizando técnicas avanzadas de aprendizaje automático (aprendizaje profundo) y un análisis de regresión. La base de datos constaba de 2023 comentarios publicados en TripAdvisor sobre dos atracciones culturales icónicas de Venecia, la Plaza de San Marcos (una atracción abierta y gratuita) y el Palacio Ducal (que cobra una tarifa de entrada). Usando técnicas de aprendizaje profundo, con regresión logística, primero identificamos qué factores influyeron en si una revisión recibió un voto de "útil". En segundo lugar, seleccionamos aquellas reseñas que recibieron al menos un voto útil para identificar, a través de una regresión lineal, los determinantes significativos del comportamiento de voto de los usuarios de TripAdvisor. Los resultados mostraron que la experiencia del revisor influye tanto en las atracciones gratuitas como en las de pago, aunque el impacto de las señales centrales (polaridad del sentimiento, subjetividad, contenido pictórico) difiere para ambas atracciones. Nuestro estudio sugiere que se debe mirar más allá de las calificaciones individuales y enfocarse en el análisis de sentimientos de las reseñas en línea, que se basan en la naturaleza de la atracción (gratis o de pago).Tourist destinations are increasingly affected by travel-related information shared through social media. Drawing on dual-process theories on how individuals process information, this study examines the role of central and peripheral information processing routes in the formation of consumers' perceptions of the helpfulness of online reviews of mature destinations. We carried out a two-step process to address the perceived helpfulness of user-generated content, a sentiment analysis using advanced machine-learning techniques (deep learning), and a regression analysis. The database was 2023 comments posted on TripAdvisor about two iconic Venetian cultural attractions, St. Mark's Square (an open, free attraction) and the Doge's Palace (which charges an entry fee). Using deep-learning techniques, with logistic regression, we first identified which factors influenced whether a review received a “helpful” vote. Second, we selected those reviews which received at least one helpful vote to identify, through linear regression, the significant determinants of TripAdvisor users' voting behaviour. The results showed that reviewer expertise is influential in both free and paid-for attractions, although the impact of central cues (sentiment polarity, subjectivity, pictorial content) differs for both attractions. Our study suggests that managers should look beyond individual ratings and focus on the sentiment analysis of online reviews, which are shown to be based on the nature of the attraction (free vs. paid-for)

Project-based learning using scientific poster as a tool for learning and acquisition of skills in physics subjects of engineering bachelor’s degrees

This article shows the experience of working on project-based learning using scientific posters, on the study of the mass geometry of matter, with students of various Physics subjects of Degrees in Engineering of the School of Design Engineering of the Polytechnic University of Valencia. The development of this work has been carried out with a dual purpose: on the one hand, to improve the teachinglearning process of mass geometry; and, on the other hand, to improve the acquisition of skills by students. This matter, which is studied in the Physics subjects of the first year of the degree, forms part of the basis of the studies of resistance of materials and theory of mechanisms of subsequent courses. The inclusion of two sessions of laboratory practices, as an extension of the work carried out in the theory and classroom practice sessions, has allowed us to study more deeply the theoretical concepts of mass geometry and their application to a real project, improving the learning by the students. In addition, the presentation of the project through the scientific poster has facilitated the acquisition of cross-curricular competencies such as application and practical thinking, teamwork, effective communication, and critical thinking

ATLAS TileCal read-out driver system production and initial performance results

8 pages, 9 figures.-- ISI Article Identifier: 000251744500005The ATLAS Hadronic Tile Calorimeter detector (TileCal) is an iron-scintillating tiles sampling calorimeter designed to operate at the Large Hadron Collider accelerator at CERN. The central element of the back-end system of the TileCal detector is a 9U VME Read-Out Driver (ROD) board. The operation of the TileCal calorimeter requires a total of 32 ROD boards. This paper summarizes the tests performed during the ROD production and the results obtained. Data processing is performed in the ROD by digital signal processors, whose operation is based on the use of online algorithms such as the optimal filtering algorithm for the signal amplitude, pedestal and time reconstruction and the online Muon tagging algorithm which identifies low transverse momentum muons. The initial performance of both algorithms run during commissioning is also presented in this paper.This work was supported by the Spanish Technology and Science Commission under project FPA2003-09220-C02-02.Peer reviewe

Algorithms for the ROD DSP of the ATLAS hadronic Tile Calorimeter

10 pages, 10 figures.-- ISI Article Identifier: 000253651100003.Final full-text version available at: http://ific.uv.es/tical/doc/2007_02_12_JINST_2_T02001.pdfIn this paper we present the performance of two algorithms currently running in the Tile Calorimeter Read-Out Driver boards for the commissioning of ATLAS. The first algorithm presented is the so called Optimal Filtering. It reconstructs the deposited energy in the Tile Calorimeter and the arrival time of the data. The second algorithm is the MTag which tags low transverse momentum muons that may escape the ATLAS muon spectrometer first level trigger.Comparisons between online (inside the Read-Out Drivers) and offline implementations are done with an agreement around 99% for the reconstruction of the amplitude using the Optimal Filtering algorithm and a coincidende of 93% between the offline and online tagged muons for the MTag algorithm. The processing time is measured for both algorithms running together with a resulting time of 59.2 μs which, although above the 10 μs of the first level trigger, it fulfills the requirements of the commissioning trigger (~ 1 Hz). We expect further optimizations of the algorithms which will reduce their processing time below 10 μs.The authors acknowledge the help of Oleg Solovyanov, Giulio Usai, Sasha Solodkov, Tomas Davidek and the whole TileCal community.Peer reviewe
