Redes sociales y consumidores: participación y construcción de imagen

This paper focuses on the “fan “ phenomenon on Facebook as the form used by consumers to express their interests, hobbies and personality, and how through such detachment to them, users participate in the process of building brand identity. This research is based on a survey between college students that analyzes the official profiles of well-known brands they follow. Studying college students behavior was preferred as this is the audience with a more developed familiarity with information and communication technologies as tools used to communicate and share contents. After exploring the official profiles users were following , we have analyzed the brands and product categories to which they belong, to understand which are the ones with the greatest draft in public preferencesLa presente investigación analiza el fenómeno “fan” en Facebook como una forma de manifestación de los usuarios de sus intereses, aficiones y personalidad, y cómo a través de dicha adscripción a unos u otros grupos los consumidores participan junto a otros usuarios en la construcción de la imagen de marca. El estudio ha trabajado sobre los perfiles oficiales de marcas renombradas, a los cuales se han adherido los estudiantes universitarios que componen la muestra. Se prefirió el análisis de dicho público por la familiaridad y el vínculo existente entre éste y las tecnologías de la información y la comunicación, como herramientas que emplea para comunicar y compartir. Así, a partir de la exploración de los perfiles oficiales de los que los usuarios eran seguidores, se han analizado las marcas y categorías de producto a las que pertenecen, para conocer cuáles son los sectores con mayor calado en las preferencias del públic

Final Report on the Evaluation of StratusLab Products

Over the course of the project, the project's software releases have been evaluated against identified requirements and against the needs of real users. Most of the formal requirements have been satisfied, with work in the second year concentrating on extentions to commercial applications, multi-platform support and sandboxing. Feedback from applications running on the StratusLab cloud can be grouped into four broad categories: Ease of Use, Integration & Operation, Better Informaton Flow, and High-Level Services. These categories provide a broad roadmap for the evolution of the StratusLab cloud distribution past the end of the project

Hybrid FE/ANN and LPR approach for the inverse identification of material parameters from cutting tests

Accuracy of numerical models based in finite elements (FE), extensively used for simulation of cutting processes, depends strongly on the identification of proper material parameters. Experimental identification of the constitutive law parameters for simulation of cutting processes involves unsolved problems such as the complex testing techniques or the difficulty to reproduce the stress triaxiality state during cutting. This work proposes a methodology for the inverse identification of the material parameters from cutting test. Two hybrid approaches are compared. One of them based on FE and artificial neural networks (ANN). The other one based on FE and local polynomial regression (LPR). Firstly, a FE model is validated with experimental data. Then, ANN and LPR are trained with FE simulations. Finally, the estimated ANN and LPR models are used for the inverse identification of material parameters. This identification is solved as an optimization problem. The FE/LPR approach shows good performance, outperforming the FE/ANN approach.The authors acknowledge the financial support of this work to the Ministry of Science and Education of Spain (under project DPI2008-06746).Publicad

Remifentanilo como analgésico para las versiones externas en la presentación podálica

INTRODUCCIÓN:En el 3-4% de los embarazos a término, el feto se encuentra en presentación podálica, lo que en la mayoría de los centros en nuestro país, es indicación de cesárea. Cualquier maniobra destinada a reducir la tasa de estas intervenciones quirúrgicas en nuestros hospitales, debería ser tenida muy en cuenta. La versión cefálica externa (VCE) es una maniobra recomendada y muy efectiva para convertir estas presentaciones en cefálicas, aunque es bastante dolorosa para la madre. El objetivo de este estudio es evaluar la eficacia y la seguridad del remifentanilo al compáralo con placebo para el tratamiento del dolor en las VCE.MÉTODOS: Ensayo clínico doble ciego, aleatorizado, controlado y paralelo. Se incluyeron a todas las gestantes de 36 y 41 semanas, con presentación no cefálica, que cumplían criterios de inclusión en el estudio. Tras la firma del consentimiento informado las pacientes fueron aleatorizada para recibir: Paracetamol 1g endovenoso seguido de remifentanilo en perfusión continua a 0,1 mcg/kg/min, más bolos a 0,1 mcg/kg o Paracetamol 1g endovenoso seguido de placebo. El objetivo principal, el dolor tras el procedimiento se determino según la escala verbal numérica (EVN). RESULTADOS: Se reclutaron 60 pacientes (29 grupo control, 31 grupo intervención). Se observaron diferencias en el EVN al final del proceso (p=0,005) con una media de 6,5±2,4 en el grupo control, y de 4,7±2,5 en el grupo intervención. Sin embargo en el EVN a los 10 minutos (p=0,054) no se observan diferencias. La tasa de éxito global fue del 49%. En el grupo que recibio remifentanilo se observaron 2 casos de nauseas y vómitos, y uno de somnolencia que se resolvió espontáneamente. En el grupo control se observaron 4 casos: 2 nauseas y vómitos, 1 bradicardia fetal y 1 mareo.CONCLUSIONES: La administración de analgesia endovenosa con remifentanilo en perfusión continua y bolos de rescate a demanda en las VCE, disminuye significativamente el dolor de las mujeres en las VCE, con un buen perfil de seguridad.Departamento de Biología Celular, Histología y Farmacologí

Service Orchestration on a Heterogeneous Cloud Federation

During the last years, the cloud computing technology has emerged as a new way to obtain computing resources on demand in a very dynamic fashion and only paying for what you consume. Nowadays, there are several hosting providers which follow this approach, offering resources with different capabilities, prices and SLAs. Therefore, depending on the users' preferences and the application requirements, a resource provider can fit better with them than another one. In this paper, we present an architecture for federating clouds, aggregating resources from different providers, deciding which resources and providers are the best for the users' interests, and coordinating the application deployment in the selected resources giving to the user the impression that a single cloud is used

Influence of tool geometry and numerical parameters when modeling orthogonal cutting of LFRP composites

The first objective of this paper is to analyze the influence of mesh size and shape in finite element modeling of composite cutting. Also the influence of the level of energy needed to reach complete breakage of the element is considered. The statement of this level of energy is crucial to simulate the material behavior. On the other hand geometrical characteristics of the tool have significant influence on machining processes. The second objective of the present work is to advance in the knowledge concerning tool geometry and its effect in composite cutting. A two-dimensional finite element model of orthogonal cutting has been developed and validated for Glass LFRP composite, comparing with experimental results presented in scientific literature. It was demonstrated that both numerical parameters and tool geometry influence the predicted chip morphology and machining induced damage.The authors are indebted for the financial support of this work, to the Ministry of Science and Innovation of Spain (under Project DPI2008 06746)Publicad

Multi-objective optimization analysis of cutting parameters when drilling composite materials with special geometry drills

The cutting tool geometry is strongly influencing damage induced during drilling of composite materials. The searching of new and optimum geometries reducing the damage on the laminates is still a challenge for the scientific community and industry. This study focuses on drilling woven CFRP laminates with four different tool geometries, analyzing the influence of the cutting parameters on the cutting forces and delamination damage. The work is divided in three phases; the first phase carries out a full factorial design of experiments conducted to quantify the significance of each process parameter as well as its interaction, on the generation of delamination at the hole entry and exit as well as the thrust force and torque. The second phase uses the response surface methodology (RSM) to establish the relationships between each output variable and the input variables based on ANOVA results. Finally, a multi-objective optimization strategy has been presented using the fitting equations to select optimum ranges of design parameters that can minimize collectively the aforementioned output variables. Ultimate objective is the process improvement toward negligible defects during drilling of woven CFRP composites.The researchers are indebted to the Ministerio de Economía y Empresa de España (Projects DPI2017-89197-C2-1-R and DPI2017-89197-C2-2-R) for the financial support which permitted to conduct part of this work as well as the Ministerio the Ciencia, Innovación y Universidades (Juan de la Cierva program with the reference FJCI-2017-34910
