Parkinson's disease management through ICT: the REMPARK approach

dc., 11/15/2017 - 20:11
Parkinson's disease management through ICT: the REMPARK approach Parkinson's Disease (PD) is a neurodegenerative disorder that manifests with motor and non-motor symptoms. PD treatment is symptomatic and tries to alleviate the associated symptoms through an adjustment of the medication. As the disease is evolving and this evolution is patient specific, it could be very difficult to properly manage the disease. The current available technology (electronics, communication, computing, etc.), correctly combined with wearables, can be of great use for obtaining and processing useful information for both clinicians and patients allowing them to become actively involved in their condition. Parkinson's Disease Management through ICT: The REMPARK Approach presents the work done, main results and conclusions of the REMPARK project (2011 - 2015) funded by the European Union under contract FP7-ICT-2011-7-287677. REMPARK system was proposed and developed as a real Personal Health Device for the Remote and Autonomous Management of Parkinson's Disease, composed of different levels of interaction with the patient, clinician and carers, and integrating a set of interconnected sub-systems: sensor, auditory cueing, Smartphone and server. The sensor subsystem, using embedded algorithmics, is able to detect the motor symptoms associated with PD in real time. This information, sent through the Smartphone to the REMPARK server, is used for an efficient management of the disease. Implementation of REMPARK will increase the independence and Quality of Life of patients; and improve their disease management, treatment and rehabilitation.

INTM 597 - Special projects

dc., 11/15/2017 - 19:54
INTM 597 - Special projects Laucirica, Jorge This paper is comprised in the entrepreneurship area and maps out the aspects that have to be taken into consideration to raise up the startup Waveland. Waveland is conceived to be the next Instagram for surf checking, an app that will enable surfers to discover in real time which are the surfing conditions in their favorite surf spots. The content of this report goes through the identification of a problem that hasn’t yet been solved by the industry. It is discovered a gap between the service that the already stablished competitors provide and what the users really need. This is explained in the first chapter of the report, the introduction. After that, the report goes about the market and competitors, the competitive advantage of Waveland, the go to market strategy, the profit formula and the organization that will manage the company. The project objective is to define the strategy that the entrepreneur should follow to start up this business as well as develop the first beta version of the app. The scope of the project is the first two years of business, which comprises launching the app in Basque country, stablish there, and then expand to the rest of Spain and nearer countries: France and UK. As a result of these last 9 months of work, I have come up with a roadmap to start that process, in which has been proved the feasibility of the project in economical, legal and strategic terms. Additionally, I have developed the first version of the app, available at iOS and Android.

Pluralistic ignorance: Conceptual framework, antecedents and consequences

dc., 11/15/2017 - 19:44
Pluralistic ignorance: Conceptual framework, antecedents and consequences Mendes, Alcindo; Lopez-Valeiras, Ernesto; Lunkes, Rogerio Joao Purpose: The aim of this paper is to present, in an integrated manner, the knowledge acquired about pluralistic ignorance in the fields of social psychology, sociology and business. Particularly, to identify the factors that work as antecedents of pluralistic ignorance, as well as its consequences, in various research contexts. Design/methodology: This integrative study on pluralistic ignorance was conducted with the Proknow-C method, which allows the construction of knowledge through a structured process of search and identification of a bibliographic portfolio. Findings: The major results include the literature review and the identification of research networks such as Allport, O'Gorman, Shamir and Miller in the field social psychology and Harvey, Buckley and Halbesleben in organizations. A systemic analysis showed how pluralistic ignorance is formed, and clarified the difference between perceptual and inferential ignorance. The systemic analysis resulted in a model with seven social comparison errors that can be seen as antecedents of ignorance and a framework with its consequences, divided into three categories: people's attitude, people's behavior and organizational capabilities. Research limitations/implications: As with every research review, identification and review of the literature depend on the authors' world view. One of the difficulties in researching pluralistic ignorance is that it is studied in different areas of knowledge and from different perspectives. Originality/value: The knowledge acquired throughout more than eight decades of research on pluralistic ignorance is fragmented into different perspectives. However, what was shown by the systemic analysis of the literature is that studies are more often geared toward psychosocial issues and it is still not very well known how the causes and consequences of pluralistic ignorance interact with the management processes in the organizational environment. This review presents a model for guiding the process of formation of pluralistic ignorance and a guiding framework for future research, as far as its consequences are concerned.

Design, modeling, and manufacturing of functionally graded sandwich panels

dc., 11/15/2017 - 19:35
Design, modeling, and manufacturing of functionally graded sandwich panels Riu Martínez, Josep Oriol Sandwich materials are structures made of two stiff skins and a softer lightweight core in between them. The function of the core is to separate the face sheets without significantly increasing the weight, thus increasing the moment of in- ertia of the structure. This makes sandwich structures convenient and eficient to resist bending and buckling loads while keeping a light weight, especially for applications where the weight is a critical factor (such as naval, aerospace, the transport industry and sporting equipment). For applications requiring resistance to impact loading (such as ship hulls, armors, helmets. . . ) sandwich materials have good capabilities in absorbing energy. The face sheets are designed to resist penetration/fracture, while the core is comprised of a material able to deform at a controlled level of stress providing isolation and damping of vibrations. The possible modes of failure of a sandwich panel are: face yielding or fracture, face and core indentation, face wrinkling (local buckling of the face sheets), core failure (usually in shear), and failure in the bonding between the core and the face sheets. This last one is the most diffcult to analyze because delamination is affected by the nature of the interface between the two ma- terials and also depends on the kind of adhesive being used. Oftentimes the adhesive is stronger than the core itself, so the bond is not a problem unless an interfacial crack appears which may propagate and separate the structure. Functionally graded materials (FGM) are characterized by the gradual vari- ation of the composition over the volume, which implies a gradual variation of the mechanical properties. This concept can be used in a sandwich struc- ture in order to enhance its performance and better tailor its properties. More precisely, the concept of FGM can be used in sandwich structures to im- prove the interface between the face sheets and the core, making it a smooth transition between materials, in order to mitigate the bonding failure and de- lamination at the interface. Multi-material Additive Manufacturing has created the opportunity of building structures that contain diferent materials with very dissimilar me- chanical properties integrated in the same body. This technology can allow manufacturing complex parts while controlling at a microscopic scale the lo- cal composition of the material being printed, which can be used to generate functionally graded materials. In this project, the device used is a Strata- sys Objet260 Connex3 which can print blending up to three diferent base materials in the same part, although only a two material gradation has been studied. The objective of this work is to design, manufacture, and model the me- chanical behavior of functionally graded sandwich beams, in order to obtain optimized combinations of stifness and damping. For this purpose, the vis- coelastic mechanical properties of the base 3-D printed materials (i.e. Ve- roCyan and TangoBlack+) have been obtained experimentally using varioustechniques. Three diferent designs of graded sandwich structures have been proposed and modeled: linear graded face sheets, quadratic graded face sheets and quadratic graded core.

Erstellung eines Simulationsmodells für pneumatische Lamellenmotoren

dc., 11/15/2017 - 19:18
Erstellung eines Simulationsmodells für pneumatische Lamellenmotoren Vidal Mas, Joan Zur Wandlung pneumatischer in mechanische Energie kommen Druckluftmotoren zum Einsatz. Es existieren verschiedene Bauformen wie z.B. Lamellenmotoren und Radialkolbenmotoren. Im Vergleich zu Elektromotoren haben die Luftmotoren ein höheres spezifisches Drehmoment. Sie sind robuster als andere Arten von Motoren und brauchen weniger Wartung. Die Möglich-keit, das Drehmoment und die Drehzahl nur mit dem Eingangsdruck und dem Abluftmassen-strom zu regeln, ist ein weiterer Vorteil. Die verschiedenen Bauformen unterscheiden sich ins-besondere durch ihr maximales Drehmoment wobei die Kolbenmotoren das höchste spezifische Drehmoment liefern. Ziel der Arbeit ist die Erstellung eines Lamellenmotormodells in Matlab/Simulink. Es wird ein mathematisches Modell für einen Motor mit einer veränderlichen Anzahl von Lamellen imple-mentiert. Außerdem werden die Reibung und auch die Leckage berücksichtigt. Es soll ein Mo-dell entwickelt werden, das die Variation von Parametern wie der Anzahl von Lamellen, des Eingangsdruck sowie des Ausgangsdrucks ermöglicht. Berechnet werden die Leistung, das Drehmoment und die Drehzahl des Lamellenmotors. Die Erstellung des Modells erfolgt in Matlab/Simulink. Vor den entsprechenden mathematischen Analysen und der Implementierung wird eine Literaturrecherche über den Stand der Technik von Lamellenmotoren und bisherige Simulationsansätze durchgeführt. Um die Überprüfung des Modells durchzuführen, wird das Drehmoment eines Lamellenmotors an einem Prüfstand in Abhängigkeit vom Versorgungsdruck und dem zugeführten Luftmassen-stromgemessen. Auf Basis der experimentellen Daten kann das erstellte Modell validiert wer-den.

Factibilidad tecnicoeconómica de la producción de tablas de surf ecoamigables

dc., 11/15/2017 - 19:18
Factibilidad tecnicoeconómica de la producción de tablas de surf ecoamigables Oliva Farriol, Jordi En este informe se desarrolla un modelo de negocio, basado en la producción de tablas de surf con materiales sostenibles, que pretende competir con la tecnología tradicional de la industria del surf. El análisis FODA realizado muestra la oportunidad en el mercado existente, destacando el hecho de que no existe un modelo de negocio similar en el país. La amenaza principal es el desconocimiento de los usuarios de tablas de surf acerca de la tecnología del producto. La propuesta de valor es atractiva y actual, siendo una de las fortalezas principales del proyecto de estudio. La misión y visión del proyecto se resumen en la intención de generar un cambio en la industria y en la concienciación ambiental del panorama de surf, actuando de forma local para conseguir un impacto global. Destaca la importancia de la Responsabilidad Social Corporativa en todas las decisiones de la empresa. El know-how desarrollado en un proyecto anterior, permite un sistema de manufactura que simplifica el proceso constructivo y por ende, una reducción notable de los costos. Mediante el modelo costos ad hoc para la producción de tablas con la tecnología alternativa propuesta se comprueban los costos de fabricación del producto El estudio de mercado determina la división de éste en 4 segmentos diferenciados: Principiante, Avanzado, Old School y Eco-friendly. Se apuesta por una estrategia de cobertura completa de todos estos segmentos y se presentan 6 productos diferentes para satisfacer la demanda: Shortboard, ShortClassic, Evolutiva, Midlength, Longboard y LongClassic. La estrategia corporativa define dos unidades estratégicas de negocios (UEN) dirigidas a dos grupos de segmentos diferentes. De esta manera se generan sinergias entre ellas y se consigue poder disfrutar de economías de escala. Son las líneas de negocio siguientes:  GKBoards: Esta UEN sigue una estrategia del especialista, dirigido al segmento Principiante, basada en el liderazgo en costes. Se elige la estrategia de dominación a través de los costes gracias a la ventaja competitiva interna de desarrollo de la tecnología.  Good Karma Surfboards: Se desarrolla en un océano azul ofreciendo un producto diferenciado. Los factores de competencia creados son los conceptos de responsabilidad social y sostenibilidad relacionados a una marca verde. La diferenciación también reside en el aumento de la vida útil del producto y la eliminación del protagonismo de los diseñadores de las tablas de surf. Se dirige la oferta a los segmentos Avanzado, Old School y Eco-friendly. 4 La estrategia de internacionalización se fija a largo plazo mediante la venta de licencias de fabricación a talleres locales de Chile Central. Su incorporación al mercado chileno dependerá de los ritmos de crecimiento de la marca en el país de origen. El análisis económico demuestra la viabilidad del proyecto obteniendo un VAN de 10.907,70€ y una TIR del 15,58% con un Payback de 4 años. Se proyecta una magnitud del proyecto de 19.746€ por lo que se la considera una baja inversión inicial. Esto permite mantener unos bajos costos fijos respecto a la competencia con tecnologías CNC. El punto de equilibrio se sitúa en 110 tablas anuales. Los diferentes análisis de sensibilidad demuestran la importante afectación de los precios de venta, el proyecto es viable hasta con una reducción del 5% de éstos. Se destaca la elevada sensibilidad de la variación de precios al resultado económico. Ésta se justifica con la elección de precios de venta ajustados, para poder competir con la industria tradicional. Se busca una diferenciación del producto igualando los precios de la competencia. Se consigue mediante la innovación del valor propuesta por la estrategia de océano azul. En cuanto a la afectación del Mix de la demanda, se fija en un 85% como máximo de producción de la familia de productos de GKboards, para la viabilidad del proyecto. Finalmente, el modelo de negocio planteado muestra la importancia de Entropy Resins como socio clave del desarrollo de este proyecto, cobrando parte del protagonismo en la estrategia de internacionalización. También se detallan las relaciones con cada segmento de clientes y el tipo de trato diferenciado para cada uno de ellos: trato personalizado para la línea Good Karma Surfboards e información a través de web para la línea GKBoards. En cuanto a recursos clave destacan la tecnología CNC y los conocimientos de técnicas de aplicación de composites. Se concluye que se trata de un proyecto que puede reportar grandes beneficios medioambientales a la industria del surf, impulsando el cambio de mentalidad en el consumo de sus productos. La apuesta por la sostenibilidad de esta empresa parte de la premisa “Piensa global, actúa local”.

Computing size-independent matrix problems on systolic array processors

dc., 11/15/2017 - 14:14
Computing size-independent matrix problems on systolic array processors Navarro Guerrero, Juan José; Llaberia Griñó, José M.; Valero Cortés, Mateo A methodology to transform dense to banded matrices is presented in this paper. This transformation, is accomplished by triangular blocks partitioning, and allows the implementation of silutions to problems with any given size, by means of contraflow systolic arrays, originally proposed by H.T. Kung. Matrix-vector and matrix-matrix multiplications are the operation considered here. The proposed transformations allow the optimal utilization of processing elements (PE's) of the systolic array when dense matrix are operated. Every computation is made inside the array by using adequate feedback. The feedback delay time depends only on the systolic array size. This work was supported by the Ministery of Education of Spain (CAYCIT) under Grant Number 2906-83 C03-03

Seguimiento del proceso constructivo del Hostal Belvillage Stepanyan, Ani I joined the company in June of 2016, thanks to the training contract offered by the university. Since then until now I have been able to complement my theoretical knowledge acquired during my degree with the practical training of the works. From my point of view, the practice is fundamental in our profession, that is why, having entered a construction company has allowed me to see for myself everything that involves a construction project from its beginning to the end, including after-sales services. I have learned that when it comes to building we are not only dedicated to that, we are also managers of our works, because apart from producing we have to achieve other objectives, and one of the most important is the control of costs. We have to get some benefits for the company, for that we have to know how to use the necessary and indispensable resources and keeping the planning. By working at the job site, it has taught me that the works are not identical to how they appear in the blueprints and at all times you can have unexpected incidences that you should find a quick and adequate solution for everyone.

Avaluació de diferents fonts de sucre per a la segona fermentació dels vins escumosos

dc., 11/15/2017 - 13:18
Avaluació de diferents fonts de sucre per a la segona fermentació dels vins escumosos Angles Munne, Guillem Cava is a very characteristic product of Catalunya, and in order to produce cava the "champenoise" method is used. This method consists on provoking a second fermentation in the bottle. Parting from a base wine, and with the addition of yeast Saccharomyces cerevisiae addition of a source of sugar (sucrose or concentrate grape juice). The overall objective of this is to develop a natural sparkling wine using "tiratge" liqueur made with raw sugar, honey or concentrated white grape and compare it with the sparkling wine made with "tiratge" liqueur made with white sugar (sucrose) which is the most common source of sugar used in the production of cava In order to make this product, we parted from the same "peu de cuba" and the same base wine, but making four different runs with each source of sugar and a total of 12 bottles for each source. Their fermentative evolution was analyzed during the first month after bottling; the yeast population, pressure and residual sugars present in the bottles after 3 months; finally, after 10 months of aging in the bottle, a physico-chemical analysis (pH, total acidity, degree of alcohol, total polyphenol index, and color intensity) and a sensorial analysis has been done. The different sources of sugar studied have presented a proper fermentation, obtaining sparkling wines with significant differences from the point of view of physic-chemical, and acceptable ones from a sensory perspective. We can say that sugar sources like raw sugar, honey and concentrated grape juice are viable options for the production of natural sparkling wines.; El cava és un producte molt característic de Catalunya, i per tal d'elaborar-lo s'utilitza el mètode "champenoise". Aquest mètode consisteix en provocar una segona fermentació en botella partint d'un vi base mitjançant l'adició de llevats Saccharomyces cerevisiae i una font de sucre (sacarosa o most concentrat). L'objectiu general del treball és elaborar vi escumós natural utilitzant licor de tiratge preparat amb sucre morè, o mel, o most concentrat no rectificat i comparar-lo amb el cava elaborat amb licor de tiratge preparat amb sucre blanc (sacarosa), que és la font de sucre més utilitzada en l'elaboració del cava. Per tal de realitzar aquest treball s'ha partit d'un mateix peu de cuba i d'un mateix vi base, fent quatre tiratges diferents amb cada font de sucre i un total de 12 ampolles per cada font. D'aquetes s'ha analitzat l'evolució fermentativa durant el primer mes desprès del tiratge; la població de llevats, pressió i sucres residuals que presenten als tres mesos en ampolla; i finalment, amb deu mesos d'envelliment en ampolla, s'ha procedit al desgorjat i posterior anàlisis fisicoquímic (pH, acidesa total, grau alcohòlic, índex de polifenols totals i intensitat colorant) i anàlisis sensorial. Les diferents fonts de sucres estudiantes han presentat una correcta fermentació, obtenint vins escumosos amb diferències significatives des del punt de vista fisicoquímic i acceptables des del punt de vista sensorial. Es pot afirmar que les fonts de sucre estudiades com sucre de canya morè, mel i most concentrat són opcions viables a considerar en l'elaboració de vins escumosos naturals.; El Cava es un producto muy característico de Catalunya, i para elaborarlo se usa el método "champenoise". Este método consiste en provocar una segunda fermentación en botella partiendo de un vino base y la adición de levaduras Saccharomyces cerevisae i una fuente de azúcar (sacarosa o mosto concentrado). El objetivo general del trabajo es elaborar un vino espumoso natural utilizando licor de tiraje preparado con azúcar moreno, miel o mosto concentrado de uva blanca i compararlo con el cava elaborado con un licor de tiraje preparado con azúcar blanco (sacarosa) que es la fuente de azúcar más utilizada en la elaboración del cava. Para poder realizar este trabaje se ha partido de un mismo pie de cuba y de un mismo vino base, haciendo cuatro tirajes diferentes con cada fuente de azúcar y un total de 12 botellas por cada fuente. De estas se ha analizado la evolución fermentativa durante el primer mes después del tiraje; la población de levaduras, presión y azúcares residuales que contienen las botellas a 3 meses de embotellado; finalmente, a los 10 meses se ha procedido a un análisis fisicoquímico (pH, acidez total, grado alcohólico índice de polifenoles totales e intensidad colorante). Las diferentes fuentes de azúcar estudiadas han presentado una correcta fermentación, obteniendo vinos espumosos con diferencias significativas des del punto de vista fisicoquímico y aceptables desde un punto de vista sensorial. Se puede afirmar que las fuentes de azúcar estudiadas como el azúcar moreno, la miel y el mosto concentrado son opciones viables para la elaboración de vinos espumosos naturales.

Deriving specifications of embeddings in recursive program design

dc., 11/15/2017 - 12:55
Deriving specifications of embeddings in recursive program design Roselló Balanyà, Celestí; Balcázar Navarro, José Luis; Peña Marí, Ricardo The design of recursive functions is a well-studied subject. Design methods require a specification to start with, however, when an embedding design is attempted at, it is not clear how the specification of the embedding relates to that of the initial function. We propose a method for deriving specifications of embeddings. We show how other known formal methods, such as loop derivation or program transformation, can be related to our method in a clear fashion. The use of embedding to enhance the efficiency of programs is also discussed.
