Aplicación lectora de datos públicos sobre DNIE

Con la llegada de la era de la información, viendo esta era como la necesidad de informatizar, registrar y tratar una gran cantidad de datos mediante la tecnología, se está dando el paso de diversos procesos burocráticos a medios tecnológicos cambiando el papel por los datos almacenados en las computadoras. El DNI electrónico permite a un individuo identificarse mediante un dispositivo donde se almacenan los datos de éste para poder identificarse unívocamente ante aquellos trámites que antaño costaban largos procesos burocráticos en papel. Sabemos que las aplicaciones software son aquellos módulos formado por un conjunto de programas y rutinas que permiten a los diferentes tipos de computadores realizar tareas de manera parcial o totalmente automáticas. Por ello este proyecto demuestra todo el proceso de creación de un módulo software, que cómo comentamos en el primer párrafo, permitiría sobrellevar otros tantos procesos burocráticos como sería la petición del DNI y posterior escritura a mano en distintas situaciones. Todo ello orientado desde un estricto análisis desde el punto de vista de la ingeniería del software. ABSTRACT Due to the fact that we’re in the era of information technology, and from the perspective that this era means to computerize register and treat a big quantity of data through technologic means, we are stepping into a process where all the bureaucracy is being transferred from paper to digital storage models. Hence, the electronic DNI allows the citizen to identify himself univocally against processes that back in time where made through tedious and heavy-paper-work processes. We know that software apps are modules conformed by a set of instructions and programs that make possible the execution of partially or totally automated tasks. That’s why this project shows the process of the creation of a software module (app) that, as we stated before, would allow overcoming many other bureaucratic processes like the request to write down the national identification number. All of it focused to a strict analysis from software engineering’s point of view.

Validación de sistemas constructivos de los cerramientos de la edificación mediante la aplicación de los métodos de decisión multicriterio : aplicación al catálogo de elementos constructivos del Código Técnico de la Edificación

Como punto de partida para el desarrollo de la Tesis, se mantiene la hipótesis de que es posible establecer métodos de evaluación global sobre el grado de utilidad de los sistemas constructivos correspondientes a los cerramientos de la edificación. Tales métodos habrían de posibilitar, de entre una serie finita de sistemas alternativos, cuáles de ellos son los objetivamente más adecuados para su selección en un entorno de decisión concreto, y habrían de permitir fundamentar la justificación objetiva de tal decisión. Paralelamente a esta hipótesis de carácter general, se planteó desde el inicio la necesidad de comprobación de una hipótesis de partida particular según la cual los sistemas constructivos basados en la utilización de componentes prefabricados, o procesos de puesta en obra con un alto grado de industrialización arrojarían valores de utilidad mayores que los sistemas tradicionales basados en la albañilería. Para la verificación de estas dos hipótesis de partida se ha procedido inicialmente a la selección de un conjunto coherente de doce sistemas de cerramientos de la edificación que pudiese servir como testigo de su diversidad potencial, para proceder a su valoración comparativa. El método de valoración propuesto ha entrado a considerar una serie de factores de diversa índole que no son reducibles a un único parámetro o magnitud que permitiese una valoración de tipo lineal sobre su idoneidad relativa, ni que permitiese establecer un grado de prelación entre los distintos sistemas constructivos alternativos de manera absoluta. Para resolver este tour de force o desafío metodológico se ha acudido a la aplicación de metodologías de valoración que nos permitiesen establecer de forma racional dicha comparativa. Nos referimos a una serie de metodologías provenientes en primera instancia de las ciencias exactas, que reciben la denominación de métodos de ayuda a la decisión multicriterio, y en concreto el denominado método ELECTRE. Inicialmente, se ha planteado la aplicación del método de análisis sobre doce sistemas constructivos seleccionados de tal forma que representasen de forma adecuada las tres categorías establecidas para caracterizar la totalidad de sistemas constructivos posibles; por peso, grado de prefabricación y grado de ventilación. Si bien la combinación de las tres categorías básicas anteriormente señaladas produce un total de 18 subcategorías conceptuales, tomamos finalmente doce subcategorías dado que consideramos que es un número operativo suficiente por extenso para el análisis propuesto y elimina tipos no relevantes. Aplicado el método propuesto, a estos doce sistemas constructivos “testigo”, se constata el mayor grado de utilidad de los sistemas prefabricados, pesados y no ventilados. Al hilo del análisis realizado en la Parte II de la Tesis sobre los doce sistemas constructivos “testigo”, se ha realizado un volcado de los sistemas constructivos incluidos en el Catalogo de Elementos Constructivos del CTE (versión 2010) sobre las dieciocho subcategorías definidas en dicha Parte II para caracterizar los sistemas constructivos “testigo”. Posteriormente, se ha procedido a una parametrización de la totalidad de sistemas constructivos para cerramientos de fachadas incluidos en este Catálogo. La parametrización sistemática realizada ha permitido establecer, mediante el cálculo del valor medio que adoptan los parámetros de los sistemas pertenecientes a una misma familia de las establecidas por el Catálogo, una caracterización comparativa del grado de utilidad de dichas familias, tanto en lo relativo a cada uno de los parámetros como en una valoración global de sus valores, de carácter indicativo. Una vez realizada una parametrización completa de la totalidad de sistemas constructivos incluidos en el Catálogo, se ha realizado una simulación de aplicación de la metodología de validación desarrollada en la Parte II de la presente Tesis, con el objeto de comprobar su adecuación al caso. En conclusión, el desarrollo de una herramienta de apoyo a la decisión multicriterio aplicada al Catálogo de Elementos constructivos del CTE se ha demostrado técnicamente viable y arroja resultados significativos. Se han diseñado dos sistemas constructivos mediante la aplicación de la herramienta desarrollada, uno de fachada no ventilada y otro de fachada ventilada. Comparados estos dos sistemas constructivos mejorados con otros sistemas constructivos analizados Se comprueba el alto grado de utilidad objetiva de los dos sistemas diseñados en relación con el resto. La realización de este ejercicio de diseño de un sistema constructivo específico, que responde a los requerimientos de un decisor concreto viene a demostrar, así pues, la utilidad del algoritmo propuesto en su aplicación a los procesos de diseño de los sistemas constructivos. La tesis incorpora dos innovaciones metodológicas y tres innovaciones instrumentales. ABSTRACT The starting point for the thesis is the hypothesis that it is possible to devise suitability degree evaluation methods of building enclosure systems. Such methods should allow optimizing appraisal, given a specific domain of decision, among a finite number of alternative systems, and provide objective justification of such decision. Along with the above mentioned general assumption, a second hypothesis whereby constructive systems based on the use of prefabricated components, or high industrialization degree work processes, would throw efficiency values higher than traditional masonry systems needed to be tested. In order to validate these two hypothesis a coherent set of twelve enclosure systems that could serve as a reference sample of their potential diversity was selected and a comparative evaluation was carried out. The valuation method proposed has considered several different factors that are neither reducible to a single parameter or magnitude that would allow a linear evaluation of their relative suitability nor allow to establishing an absolute priority ranking between different alternative constructive systems. In order to resolve this tour de force or methodological challenge, valuation methodologies that enable use establishing rational assessments were used. We are referring to a number of methodologies taken from the exact sciences field, usually known as aid methods for multi-criteria decision, in particular the so-called ELECTRE method. Even though the combination of the mentioned three basic categories result in eighteen conceptual sub categories, we are finally considering just twelve since we deem it adequately extended for the our intended purpose and eliminates non relevant instances. The method of analysis was initially applied to the set of twelve selected constructive systems is a way that they could represent adequately the three previously established categories set out to characterize all possible enclosure systems, namely weight, prefabrication degree and ventilation degree. Once the proposed method is applied to the sample systems, the higher efficiency of the prefabricated, heavy and not ventilated systems was confirmed. In line with the analysis in Part II of the thesis on the twelve chosen enclosure systems, it has done an uploading data of construction systems listed in the Catalogue of constructive elements of the CTE (version 2010) according the eighteen subcategories used in this part II to characterize the construction systems taken as sample. Subsequently, a parameterization of all enclosure facade systems included in this catalog has been undertaken. The systematic parameterization has allowed to set, by means of calculating the average values of the parameters of the systems belonging to the same family of those established by the Catalog, a comparative characterization of the efficiency degree of these families, both in relation to each parameter as to an overall evaluation of its values, in a indicative way. After the parameterization of all enclosure systems included in the Catalog, a simulation of validation methodology application developed in Part II of this Thesis has been made, in order to assess its consistency to the referred case. In conclusion, the development of a multi-criteria decision aid tool, applied to the CTE Catalog of constructive elements, has proved to be technically feasible and yields significant results. Two building systems through the application of the developed tool, a non-ventilated façade and a ventilated façade have been designed. Comparing these two improved construction systems with other building systems analyzed, we were able to assess the high degree of objective efficiency of the two systems designed in relation to the rest. The exercise of designing a specific enclosure system that meets the requirements of a particular decision-maker hence shows the suitability of the proposed algorithm applied to the process of enclosure systems design. This Thesis includes two methodological innovations and three instrumental innovations.

Novel application for exergy and thermoeconomic analysis of processes simulated with Aspen Plus

A visual basic application for Microsoft® Excel 2007 has been developed as a helpful tool to perform mass, energy, exergy and thermoeconomic (MHBT) calculations during the systematic analysis of energy processes simulated with Aspen Plus®. The application reads an Excel workbook containing three sheets with the matter, work and heat streams results of an Aspen Plus® simulation. The required information from the Aspen Plus® simulation and the algorithm/calculations of the application are described and applied to an Air Separation Unit (ASU). This application helps the designer when MHBT analyses are performed, as it increases the knowledge of the process simulated with Aspen Plus®. It’s a valuable tool not only because of the calculations performed, but also because it creates a new Excel workbook where the results and the formulae written on the cells are fully visible and editable. There is free access to the application and it has no protection allowing changes and improvements to be done.

Commonalities between networking in multiplayer computer games and negotiation processes in a future multi-layered Air Traffic Management (ATM) system

First, this paper describes a future layered Air Traffic Management (ATM) system centred in the execution phase of flights. The layered ATM model is based on the work currently performed by SESAR [1] and takes into account the availability of accurate and updated flight information ?seen by all? across the European airspace. This shared information of each flight will be referred as Reference Business Trajectory (RBT). In the layered ATM system, exchanges of information will involve several actors (human or automatic), which will have varying time horizons, areas of responsibility and tasks. Second, the paper will identify the need to define the negotiation processes required to agree revisions to the RBT in the layered ATM system. Third, the final objective of the paper is to bring to the attention of researchers and engineers the communalities between multi-player games and Collaborative Decision Making processes (CDM) in a layered ATM system

Estudios termodinámicos de los procesos de vitrificación en la crioconservación de germoplasma vegetal=Thermodynamic studies of vitrification processes in plant germplasm cryopreservation

En la actualidad, las técnicas de crioconservación poseen una importancia creciente para el almacenamiento a largo plazo de germoplasma vegetal. En las dos últimas décadas, estos métodos experimentaron un gran desarrollo y se han elaborado protocolos adecuados a diferentes sistemas vegetales, utilizando diversas estrategias como la vitrificación, la encapsulación-desecación con cuentas de alginato y el método de “droplet”-vitrificación. La presente tesis doctoral tiene como objetivo aumentar el conocimiento sobre los procesos implicados en los distintos pasos de un protocolo de crioconservación, en relación con el estado del agua presente en los tejidos y sus cambios, abordado mediante diversas técnicas biofísicas, principalmente calorimetría diferencial de barrido (DSC) y microscopía electrónica de barrido a baja temperatura (crio-SEM). En un primer estudio sobre estos métodos de crioconservación, se describen las fases de enfriamiento hasta la temperatura del nitrógeno líquido y de calentamiento hasta temperatura ambiente, al final del periodo de almacenamiento, que son críticas para la supervivencia del material crioconservado. Tanto enfriamiento como calentamiento deben ser realizados lo más rápidamente posible pues, aunque los bajos contenidos en agua logrados en etapas previas de los protocolos reducen significativamente las probabilidades de formación de hielo, éstas no son del todo nulas. En ese contexto, se analiza también la influencia de las velocidades de enfriamiento y calentamiento de las soluciones de crioconservación de plantas en sus parámetros termofísicos referente a la vitrificación, en relación su composición y concentración de compuestos. Estas soluciones son empleadas en la mayor parte de los protocolos actualmente utilizados para la crioconservación de material vegetal. Además, se estudia la influencia de otros factores que pueden determinar la estabilidad del material vitrificado, tales como en envejecimiento del vidrio. Se ha llevado a cabo una investigación experimental en el empleo del crio-SEM como una herramienta para visualizar el estado vítreo de las células y tejidos sometidos a los procesos de crioconservación. Se ha comparado con la más conocida técnica de calorimetría diferencial de barrido, obteniéndose resultados muy concordantes y complementarios. Se exploró también por estas técnicas el efecto sobre tejidos vegetales de la adaptación a bajas temperaturas y de la deshidratación inducida por los diferentes tratamientos utilizados en los protocolos. Este estudio permite observar la evolución biofísica de los sistemas en el proceso de crioconservación. Por último, se estudió la aplicación de películas de quitosano en las cuentas de alginato utilizadas en el protocolo de encapsulación. No se observaron cambios significativos en su comportamiento frente a la deshidratación, en sus parámetros calorimétricos y en la superficie de las cuentas. Su aplicación puede conferir propiedades adicionales prometedoras. ABSTRACT Currently, cryopreservation techniques have a growing importance for long term plant germplasm storage. These methods have undergone great progress during the last two decades, and adequate protocols for different plant systems have been developed, making use of diverse strategies, such as vitrification, encapsulation-dehydration with alginate beads and the dropletvitrification method. This PhD thesis has the goal of increasing the knowledge on the processes underlying the different steps of cryopreservation protocols, in relation with the state of water on tissues and its changes, approached through diverse biophysical techniques, especially differential scanning calorimetry (DSC) and low-temperature scanning electron microscopy (cryo-SEM). The processes of cooling to liquid nitrogen temperature and warming to room temperature, at the end of the storage period, critical for the survival of the cryopreserved material, are described in a first study on these cryopreservation methods. Both cooling and warming must be carried out as quickly as possible because, although the low water content achieved during previous protocol steps significantly reduces ice formation probability, it does not completely disappear. Within this context, the influence of plant vitrification solutions cooling and warming rate on their vitrification related thermophysical parameters is also analyzed, in relation to its composition and component concentration. These solutions are used in most of the currently employed plant material cryopreservation protocols. Additionally, the influence of other factors determining the stability of vitrified material is studied, such as glass aging. An experimental research work has been carried out on the use of cryo-SEM as a tool for visualizing the glassy state in cells and tissues, submitted to cryopreservation processes. It has been compared with the better known differential scanning calorimetry technique, and results in good agreement and complementary have been obtained. The effect on plant tissues of adaptation to low temperature and of the dehydration induced by the different treatments used in the protocols was explored also by these techniques. This study allows observation of the system biophysical evolution in the cryopreservation process. Lastly, the potential use of an additional chitosan film over the alginate beads used in encapsulation protocols was examined. No significant changes could be observed in its dehydration and calorimetric behavior, as well as in its surface aspect; its application for conferring additional properties to gel beads is promising.

Simulating Metabolic Processes Using an Architecture Based on Networks of Bio-inspired Processors.

In this work, we propose the Networks of Evolutionary Processors (NEP) [2] as a computational model to solve problems related with biological phenomena. In our first approximation, we simulate biological processes related with cellular signaling and their implications in the metabolism, by using an architecture based on NEP (NEP architecture) and their specializations: Networks of Polarized Evolutionary Processors (NPEP) [1] and NEP Transducers (NEPT) [3]. In particular, we use this architecture to simulate the interplay between cellular processes related with the metabolism as the Krebs cycle and the malate-aspartate shuttle pathway (MAS) both being altered by signaling by calcium.

Laser Processes for Contact Optimization in c-Si Solar Cells

Solid State Lasers (SSL) have been used in microelectronic and photovoltaic (PV) industry for decades but, currently, laser technology appears as a key enabling technology to improve efficiency and to reduce production costs in high efficiency solar cells fabrication. Moreover, the fact that the interaction between the laser radiation and the device is normally localized and restricted to a controlled volume makes SSL a tool of choice for the implementation of low temperature concepts in PV industry. Specifically, SSL are ideally suited to improve the electrical performance of the contacts further improving the efficiency of these devices. Advanced concepts based on standard laser firing or advanced laser doping techniques are optimal solutions for the back contact of a significant number of structures of growing interest in the c-Si PV industry, and a number of solutions has been proposed as well for emitter formation, to reduce the metallization optical losses or even to remove completely the contacts from the front part of the cell. In this work we present our more recent results of SSL applications for contact optimization in c-Si solar cell technology, including applications on low temperature processes demanding devices, like heterojunction solar cells.

Double ion implantation and pulsed laser melting processes for third generation solar cells

In the framework of the third generation of photovoltaic devices, the intermediate band solar cell is one of the possible candidates to reach higher efficiencies with a lower processing cost. In this work, we introduce a novel processing method based on a double ion implantation and, subsequently, a pulsed laser melting (PLM) process to obtain thicker layers of Ti supersaturated Si. We perform ab initio theoretical calculations of Si impurified with Ti showing that Ti in Si is a good candidate to theoretically form an intermediate band material in the Ti supersaturated Si. From time-of-flight secondary ion mass spectroscopy measurements, we confirm that we have obtained a Ti implanted and PLM thicker layer of 135 nm. Transmission electron microscopy reveals a single crystalline structure whilst the electrical characterization confirms the transport properties of an intermediate band material/Si substrate junction. High subbandgap absorption has been measured, obtaining an approximate value of 104 cm−1 in the photons energy range from 1.1 to 0.6 eV.

Analysing the complexity of the model-based decision making processes within the industrial management context

PURPOSE The decision-making process plays a key role in organizations. Every decision-making process produces a final choice that may or may not prompt action. Recurrently, decision makers find themselves in the dichotomous question of following a traditional sequence decision-making process where the output of a decision is used as the input of the next stage of the decision, or following a joint decision-making approach where several decisions are taken simultaneously. The implication of the decision-making process will impact different players of the organization. The choice of the decision- making approach becomes difficult to find, even with the current literature and practitioners’ knowledge. The pursuit of better ways for making decisions has been a common goal for academics and practitioners. Management scientists use different techniques and approaches to improve different types of decisions. The purpose of this decision is to use the available resources as well as possible (data and techniques) to achieve the objectives of the organization. The developing and applying of models and concepts may be helpful to solve managerial problems faced every day in different companies. As a result of this research different decision models are presented to contribute to the body of knowledge of management science. The first models are focused on the manufacturing industry and the second part of the models on the health care industry. Despite these models being case specific, they serve the purpose of exemplifying that different approaches to the problems and could provide interesting results. Unfortunately, there is no universal recipe that could be applied to all the problems. Furthermore, the same model could deliver good results with certain data and bad results for other data. A framework to analyse the data before selecting the model to be used is presented and tested in the models developed to exemplify the ideas. METHODOLOGY As the first step of the research a systematic literature review on the joint decision is presented, as are the different opinions and suggestions of different scholars. For the next stage of the thesis, the decision-making process of more than 50 companies was analysed in companies from different sectors in the production planning area at the Job Shop level. The data was obtained using surveys and face-to-face interviews. The following part of the research into the decision-making process was held in two application fields that are highly relevant for our society; manufacturing and health care. The first step was to study the interactions and develop a mathematical model for the replenishment of the car assembly where the problem of “Vehicle routing problem and Inventory” were combined. The next step was to add the scheduling or car production (car sequencing) decision and use some metaheuristics such as ant colony and genetic algorithms to measure if the behaviour is kept up with different case size problems. A similar approach is presented in a production of semiconductors and aviation parts, where a hoist has to change from one station to another to deal with the work, and a jobs schedule has to be done. However, for this problem simulation was used for experimentation. In parallel, the scheduling of operating rooms was studied. Surgeries were allocated to surgeons and the scheduling of operating rooms was analysed. The first part of the research was done in a Teaching hospital, and for the second part the interaction of uncertainty was added. Once the previous problem had been analysed a general framework to characterize the instance was built. In the final chapter a general conclusion is presented. FINDINGS AND PRACTICAL IMPLICATIONS The first part of the contributions is an update of the decision-making literature review. Also an analysis of the possible savings resulting from a change in the decision process is made. Then, the results of the survey, which present a lack of consistency between what the managers believe and the reality of the integration of their decisions. In the next stage of the thesis, a contribution to the body of knowledge of the operation research, with the joint solution of the replenishment, sequencing and inventory problem in the assembly line is made, together with a parallel work with the operating rooms scheduling where different solutions approaches are presented. In addition to the contribution of the solving methods, with the use of different techniques, the main contribution is the framework that is proposed to pre-evaluate the problem before thinking of the techniques to solve it. However, there is no straightforward answer as to whether it is better to have joint or sequential solutions. Following the proposed framework with the evaluation of factors such as the flexibility of the answer, the number of actors, and the tightness of the data, give us important hints as to the most suitable direction to take to tackle the problem. RESEARCH LIMITATIONS AND AVENUES FOR FUTURE RESEARCH In the first part of the work it was really complicated to calculate the possible savings of different projects, since in many papers these quantities are not reported or the impact is based on non-quantifiable benefits. The other issue is the confidentiality of many projects where the data cannot be presented. For the car assembly line problem more computational power would allow us to solve bigger instances. For the operation research problem there was a lack of historical data to perform a parallel analysis in the teaching hospital. In order to keep testing the decision framework it is necessary to keep applying more case studies in order to generalize the results and make them more evident and less ambiguous. The health care field offers great opportunities since despite the recent awareness of the need to improve the decision-making process there are many opportunities to improve. Another big difference with the automotive industry is that the last improvements are not spread among all the actors. Therefore, in the future this research will focus more on the collaboration between academia and the health care sector.
