Abstract: Risk analysis techniques help to identify threats, problems and anomalies in processes and systems that may affect the health and safety of employees, the environment, equipment reliability and normative compliance. In this thesis, a stochastic risk analysis with Monte Carlo simulation applied to FMECA (Failure Modes, Effects and Criticality Analysis) was performed for a specific model of wind turbine located in the Alpha Ventus offshore wind Park. Monte Carlo simulations provide the decisionmaker with a range of possible outcomes and the probabilities of occurrences of these results, that are derived mainly from the uncertainty associated to the subjectivity of judgement from a group of experts. As a supplementary method to the stochastic FMECA, Risk Assessments Matrix (RAM) was also used for bivariate distributions of Severity and Occurrence of the identified failure modes. The results obtained were compared to the results that would be normally obtained with a conventional FMECA and RAM and will serve in future steps to develop Risk-Based Inspection plans for this model of wind turbine in this offshore wind park.

Abstract: One of the recurring problems in the construction industry is its recognised lack of productivity due to different factors, among which could be highlighted the fragmentation of the information flow between the different phases of the project life cycle and the difficulty in communication between the different stakeholders. To address this, the industry has reacted through the use of prefabrication and the implementation of new technologies such as Building Information Modelling. The aim is to improve both productivity, through mass customisation, and the flow of information between phases and stakeholders in the projects, through the use of software and platforms, which also give the possibility of automation with processes such as Generative Design. The dissertation investigates the use of these technologies in the area of prefabrication in construction, focusing on the current implementation of configurators and the associated automation that could be derived from their use for the development of projects. Taking a hybrid prefabrication system (wood and concrete) currently used by CASAIS company as a case study, the research seeks to develop a framework that exploits the modular characteristics of these systems, especially in the design phase. It is in this phase where it is possible to take advantage of the limited number of parameters of the prefabricated elements in automating the generation of design proposals and in obtaining information related to KPIs, which would, in turn, allow a more objective feasibility analysis during this first phase of the project. The indicated solution is, firstly, the proposal of a methodology to develop a configurator applied to the case study, which uses tools and/or platforms, that are currently present in the market related to BIM and the construction industry. Then the dissertation continues with the specific development of the section of the methodology corresponding to the generation of the computational model, and for this purpose visual programming is used, taking as initial information the relevant parameters and data to be obtained that are typical of the prefabrication system studied. The research seeks to make a contribution to the current progress in terms of productivity and information flow that has been developed in the construction industry with the implementation of prefabrication and BIM. With the use of configurators, associated with these new technologies, an incursion into automation methods is proposed, especially in the project gestation phases through Generative Design. Thus, by making use of the mass customisation possibilities offered by prefabrication systems and the integration of nonprofessional agents, (taking advantage of the ease of use of the configurators), a more integrated design process and a more objective decision-making process can be achieved, since it is based on more accurate data related to the feasibility of the projects.

En el mercado mundial del café, la calidad del grano (aroma, sabor, cuerpo y acidez) y su consistencia, son los factores más decisivos para los clientes que motivan a un comprador a pagar un precio determinado por un producto. Cuando se cumplen ambas condiciones: consistencia y calidad de café y se suma la cantidad con frecuencia, los clientes están dispuestos a pagar un precio superior y se puede lograr una diferenciación del mismo que representa un mayor ingreso y por ende, una mayor rentabilidad y competitividad de la industria cafetalera. Con esta óptica, el proyecto se localiza en Viotá, al sur occidente del Departamento de Cundinamarca, a 86 km de Bogotá y a 12 km de la carretera troncal que comunica el interior con el sur del país. Este emprendimiento consiste en el procesamiento de café cereza en café pergamino seco demostrando condiciones viables desde lo social, financiero, mercado, medio ambiente e ingeniería. La empresa tendrá dos frentes de trabajo; uno relacionado con una planta procesadora y otro con la fuerza comercial que genera el poder de negociación que necesitan los clientes

We carried out differential measurements of temperature and image motion in a convective Rayleigh-Bénard water tank to test the assumption of Kolmogorov turbulence. Careful selection of the experimental methodology is required to arrive at the agreement between theory and experiment.

Internet ha dado un nuevo sentido al término contenidos. Los contenidos han cobrado un nuevo valor, mayúsculo, y, en cambio, la mayoría de estos contenidos se acaban ofreciendo gratuitamente. ¿Cuál es la legislación aplicable, cómo se desarrollan y cómo se evalúan estos contenidos? Además, con internet el peso de usuario de los contenidos ha crecido y ahora quien los produce se preocupa por cómo los presenta.

Ahora que Internet se consolida como campo de investigación, este libro quiere desarrollar un análisis sociohistórico y crítico en torno a las principales metáforas que se han utilizado para estudiar la Comunicación Mediada por Ordenador: el ciberespacio, la comunidad virtual y la identidad virtual.

El libro introduce el concepto de interoperabilidad tecnológica y los principales ámbitos de aplicación, como son: comercio electrónico, administración electrónica, elearning, bibliotecas digitales, y otros.

En este libro se proporcionan algunas directrices y soluciones para que la producción de contenidos web sea correcta y eficiente, tanto desde el punto de vista empresarial como desde la perspectiva de los usuarios.

Cultura 2.0. Técnicas de investigación en entornos digitales, trata de desvelar las técnicas necesarias para introducirse en el apasionante mundo de las comunicaciones mediadas por ordenador y el magnífico escenario que se abre a las ciencias sociales. A través de las experiencias de investigación de los autores en el ciberespacio, se analizan los pros y los contras de cada método. Para comprender los entornos digitales, partimos de la herencia de la antropología clásica, son viejas técnicas para nuevos tiempos, técnicas especiales para trabajos especiales. Una nueva antropología para comprender al nuevo ser humano interactuando con la máquina.
