Systematic Approach for the selection of monitoring technologies in CO2 geological storage projects. Application of multicriteria decision making

Geologic storage of carbon dioxide (CO2) has been proposed as a viable means for reducing anthropogenic CO2 emissions. Once injection begins, a program for measurement, monitoring, and verification (MMV) of CO2 distribution is required in order to: a) research key features, effects and processes needed for risk assessment; b) manage the injection process; c) delineate and identify leakage risk and surface escape; d) provide early warnings of failure near the reservoir; and f) verify storage for accounting and crediting. The selection of the methodology of monitoring (characterization of site and control and verification in the post-injection phase) is influenced by economic and technological variables. Multiple Criteria Decision Making (MCDM) refers to a methodology developed for making decisions in the presence of multiple criteria. MCDM as a discipline has only a relatively short history of 40 years, and it has been closely related to advancements on computer technology. Evaluation methods and multicriteria decisions include the selection of a set of feasible alternatives, the simultaneous optimization of several objective functions, and a decision-making process and evaluation procedures that must be rational and consistent. The application of a mathematical model of decision-making will help to find the best solution, establishing the mechanisms to facilitate the management of information generated by number of disciplines of knowledge. Those problems in which decision alternatives are finite are called Discrete Multicriteria Decision problems. Such problems are most common in reality and this case scenario will be applied in solving the problem of site selection for storing CO2. Discrete MCDM is used to assess and decide on issues that by nature or design support a finite number of alternative solutions. Recently, Multicriteria Decision Analysis has been applied to hierarchy policy incentives for CCS, to assess the role of CCS, and to select potential areas which could be suitable to store. For those reasons, MCDM have been considered in the monitoring phase of CO2 storage, in order to select suitable technologies which could be techno-economical viable. In this paper, we identify techniques of gas measurements in subsurface which are currently applying in the phase of characterization (pre-injection); MCDM will help decision-makers to hierarchy the most suitable technique which fit the purpose to monitor the specific physic-chemical parameter.

Survey on student motivation and approval of educational environment at Universidad Politécnica de Madrid within the European Higher Education area implementation

A recent study elaborated by Vicerrectorado de Ordenación Académica y Planificación Estratégica of Technical University of Madrid (UPM) defines the satisfaction of the university student body as "the response that the University offers to the expectations and demands of service of the students, considered in a general way ". Besides an indicator of academic and institutional insertion of the student, the assessment of student engagement allows us to adapt the academic offer and the extension services of the University to the real needs of the students. The process of convergence towards the European Higher Education Area (EHEA) raises the need to form in competitions, that is to say, of developing in our students capacities and knowledge beyond the purely theoretical-practical thing. Therefore, the perception and experience of the educational process and environment by the students is an important issue to be addressed to accomplish their expectations and achieve a curriculum accordingly to EHEA expectations. The present study aims to explore the student motivation and approval of the educational environment at the UPM. To this end a total of 97 students enrolled in the undergraduate program of Civil Engineering, Computer Engineering and Agronomic Engineering at UPM were surveyed. The survey consisted of 40 questions divided in three blocks. The first one of 20 questions of personal character in that they were gathering, besides the sex and the age, the degree of fulfilment, implication and dedication with the institution and the academic tasks. In the second block we identify 10 questions related to the perception of the student on the teaching quality, and finally a block of 10 questions regarding the Bologna Process. The students personal motivation was moderately high, with a score of 3.6 (all scores are provided on a 5-point scale), being the most valuable items obtaining a university degree (4,3) and the friendship between students (4,2). Any significant difference was shown between sexes (P=0.23) since the averages for this block of questions were of 3.7±0.3 and 3.5±0.4 for women and men respectively. The students are moderately satisfied with their graduate studies with an average score of 3,2, being the questions that reflect a minor satisfaction the research profile of the teachers (2,8) and the organization of the Schools (2,9). The best valued questions are related to the usefulness and quality of the degrees, with 3,5 and 3,4 respectively, and to the interest of the courses within the degree (3,4). For sexes, the results of this block of questions are similar (3.1±0.3 and 3.2±0.3 for men and women respectively=0.79). Also, there were no differences (P=0.39) between the students who arrange work and studies or do not work (3.1±0.2 and 3.2±0.3 respectively). In conclusion, students at UPM present an acceptable degree of motivation and satisfaction with regard to the studies and services that offer their respective Schools. Both characteristics receive the same value both for men and for women and so much for students who arrange work and studies as for those who devote themselves only to studying. In a significant way, students who are more engaged and are in-class attendants present the major degree of satisfaction.Overall, there is a great lack of information regarding the Bologna Process. In fact to the majority, they would like to know more on what it is, what it means and what changes will involve its implementation.

Location of bioelectricity plants in the Madrid Community based on triticale crop: a multicriteria methodology

This paper presents a work whose objective is, first, to quantify the potential of the triticale biomass existing in each of the agricultural regions in the Madrid Community through a crop simulation model based on regression techniques and multiple correlation. Second, a methodology for defining which area has the best conditions for the installation of electricity plants from biomass has been described and applied. The study used a methodology based on compromise programming in a discrete multicriteria decision method (MDM) context. To make a ranking, the following criteria were taken into account: biomass potential, electric power infrastructure, road networks, protected spaces, and urban nuclei surfaces. The results indicate that, in the case of the Madrid Community, the Campiña region is the most suitable for setting up plants powered by biomass. A minimum of 17,339.9 tons of triticale will be needed to satisfy the requirements of a 2.2 MW power plant. The minimum range of action for obtaining the biomass necessary in Campiña region would be 6.6 km around the municipality of Algete, based on Geographic Information Systems. The total biomass which could be made available in considering this range in this region would be 18,430.68 t.

Multicriteria decision analysis applied to cover crop species andcultivars selection

Cover crop selection should be oriented to the achievement of specific agrosystem benefits. The covercrop, catch crop, green manure and fodder uses were identified as possible targets for selection. Theobjective was to apply multi-criteria decision analysis to evaluate different species (Hordeum vulgareL., Secale cereale L., ×Triticosecale Whim, Sinapis alba L., Vicia sativa L.) and cultivars according to theirsuitability to be used as cover crops in each of the uses. A field trial with 20 cultivars of the five specieswas conducted in Central Spain during two seasons (October?April). Measurements of ground cover, cropbiomass, N uptake, N derived from the atmosphere, C/N, dietary fiber content and residue quality werecollected. Aggregation of these variables through utility functions allowed ranking species and cultivarsfor each usage. Grasses were the most suitable for the cover crop, catch crop and fodder uses, while thevetches were the best as green manures. The mustard attained high ranks as cover and catch crop the firstseason, but the second decayed due to low performance in cold winters. Mustard and vetches obtainedworse rankings than grasses as fodder. Hispanic was the most suitable barley cultivar as cover and catchcrop, and Albacete as fodder. The triticale Titania attained the highest rank as cover and catch crop andfodder. Vetches Aitana and BGE014897 showed good aptitudes as green manures and catch crops. Thisanalysis allowed comparison among species and cultivars and might provide relevant information forcover crops selection and management.

Relaciones entre los usos del suelo, las infraestructuras y la planificación: incidencia de la red viaria y el planeamiento en la aparición del terciario para el caso de la N-VI

Esta tesis examina el papel de la red viaria y el planeamiento urbanístico en la localización de las actividades terciarias. A partir de los años sesenta se produce una modificación de los patrones de comportamiento espacial de las actividades productivas. En la raíz de estos cambios está los procesos de globalización e internacionalización de la economía y un importante aumento de la utilización vehículos privados. Todo ello da lugar a una preocupación entre los profesionales por la identificación de variables en esa organización espacial, y por la búsqueda de modelos que mejorasen las condiciones de competitividad en el entramado urbano, reclamado también la formulación de conceptos diferentes, capaces de entender los cambios territoriales de la reestructuración permanente en que viven las economías capitalistas avanzadas. En este marco, hay un aumento importante de las actividades terciarias o proceso de terciarización; que es el principio basilar para la suburbanización de este sector. Consiste, en buena medida, en unas necesidades de descentralización y dispersión de las actividades terciarias por todo el territorio, con demandas de nuevos espacios para todo tipo de actividades empresariales. Se va así generando un espacio urbano complejo, con nuevas actividades, distintas de la residencial, y con tipologías edificatorias diferentes: centros comerciales, hipermercados, zocos o edificios de empresas dedicadas a servicios avanzados y altamente cualificados. Adquiere, por tanto, un fuerte protagonismo los espacios periféricos de las grandes ciudades. En la transformación de este territorio interviene el planeamiento urbanístico porque prevé la ocupación del suelo y la forma de uso. Y también la carretera considerada clave en el desarrollo histórico de la ciudad. Consecuentemente, se impulsan una plétora de nuevas líneas de investigación y nuevas formas de aproximación al estudio de las relaciones entre las infraestructuras viarias y los usos del suelo. El interés del proyecto de investigación es, por todo ello, estudiar en que medida la localización del terciario depende del planeamiento urbano y de las variaciones en la red viaria. Es decir, la hipótesis de este trabajo se puede enunciar diciendo que: en la aparición del terciario inciden dos variables, el planeamiento urbanístico y la red viaria; lógicamente siendo consciente de la dificultad intrínseca de separar algún parámetro y sus relaciones de un sistema funcional urbano. Centrando este enfoque sobre el caso particular del corredor de la carretera de La Coruña (N-VI) situado en el oeste de la Comunidad de Madrid. Es un ámbito suburbano que comprende los términos municipales de Las Rozas y Majadahonda, un segmento del municipio de Madrid (abarca los barrios de Aravaca, el Plantío y Valdemarín, y una pequeña superficie de la Casa de Campo, Ciudad Universitaria y El Pardo), y la mitad septentrional del municipio de Pozuelo de Alarcón. La conclusión general a la que se ha llegado es que se trata de un fenómeno complejo, en el que se detecta que: A) La aprobación de un nuevo Plan Urbanístico no supone un cambio inmediato en la evolución cuantitativa de la implantación de actividades terciarias en edificio exclusivo en el área de estudio. B) Se evidencia una relación directa entre la implantación de una nueva infraestructura de transporte o modificación de algún elemento importante y el crecimiento de la localización de actividades terciarias. C) Resulta difícil verificar que cuando confluyen mejoras o nuevas construcciones en la red viaria y una estrategia en el planeamiento dirigida a la ordenación e intervención del espacio terciario, el número de edificios terciarios aumente. ABSTRACT This thesis examines the role of road networks and urban planning in the location of tertiary activities. Since the sixties there is a modification of spatial behavior patterns of production activities. At the root of these changes is the process of globalization and internationalization of the economy and a significant increase in private car use. This leads to a concern among professionals in the identification of variables in the spatial organization, and the search for models that would improve the competitive conditions in the urban framework, also called for the formulation of different concepts, able to understand the changes territorial restructuring that live permanently in the advanced capitalist economies. In this context, there is a significant increase in tertiary activities or process outsourcing, which is the beginning basilar to the suburbanization of the sector. It consists, in large part, on the Needs of decentralization and dispersal of tertiary activities throughout the territory, demands for new spaces for all types of business activities. It is thus generating a complex urban area, with new activities, other than residential and with different building typologies: shopping malls, hypermarkets, souks and buildings of companies engaged in advanced and highly skilled services. Thus takes strong role peripheral areas of big cities. In the transformation of this region is involved in providing for urban planning land use and how to use. And the road is considered key in the historical development of the city. Consequently, they are promoting a plethora of new research and new ways of approaching the study of the relationship between road infrastructure and land use. The interest of the research project is, for all that, consider to what extent depends on the location of tertiary urban planning and changes in the road network. That is, the hypothesis of this work can be stated by saying that: the emergence of two variables affecting tertiary, urban planning and road network, of course being aware of the inherent difficulty of separating any parameters and functional relationships of an urban. Approach focusing on the particular case of the road corridor from La Coruña (N-VI) located in the west of Madrid. It is a suburban area comprising the municipalities of Las Rozas and Majadahonda, a segment of the city of Madrid (covering the districts of Aravaca, the planting and Valdemarín, and a small area of the Casa de Campo, Ciudad Universitaria and El Pardo) , and the northern half of the town of Pozuelo de Alarcón. The general conclusion has been reached is that this is a complex phenomenon, which is detected: A) The approval of a new Urban Plan is not an immediate change in the quantitative evolution of the implementation of tertiary activities in exclusive building in the study area. B) It shows a direct relationship between the introduction of a new transport infrastructure or amendment to an important and growing element of the location of tertiary activities. C) It is difficult to verify that when improvements or new construction come together in the road network and planning a strategy aimed at the management and intervention of third space, the number of commercial buildings increases.

Assessment of Hydrogen as suistinable clean energy

The progressive depletion of fossil fuels and their high contribution to the energy supply in this modern society forces that will be soon replaced by renewable fuels. But the dispersion and alternation of renewable energy production also undertake to reduce their costs to use as energy storage and hydrogen carrier. It is necessary to develop technologies for hydrogen production from all renewable energy storage technologies and the development of energy production from hydrogen fuel cells and cogeneration and tri generation systems. In order to propel this technological development discussed where the hydrogen plays a key role as energy storage and renewable energy, the National Centre of Hydrogen and Fuel Cell Technology Experimentation in Spain equipped with installations that enable scientific and technological design, develop, verify, certify, approve, test, measure and, more importantly, the facility ensures continuous operation for 24 hours a day, 365 days year. At the same time, the system is scalable so as to allow continuous adaptation of new technologies are developed and incorporated into the assembly to verify integration at the same time it checks the validity of their development. The transformation sector can be said to be the heart of the system, because without neglecting the other sectors, this should prove the validity of hydrogen as a carrier - energy storage are important efforts that have to do to demonstrate the suitability of fuel cells or internal combustion systems to realize the energy stored in hydrogen at prices competitive with conventional systems. The multiple roles to meet the fuel cells under different conditions of operation require to cover their operating conditions, many different sizes and applications. The fourth area focuses on integration is an essential complement within the installation. We must integrate not only the electricity produced, but also hydrogen is used and the heat generated in the process of using hydrogen energy. The energy management in its three forms: hydrogen chemical, electrical and thermal integration requires complicated and require a logic and artificial intelligence extremes to ensure maximum energy efficiency at the same time optimum utilization is achieved. Verification of the development and approval in the entire production system and, ultimately, as a demonstrator set to facilitate the simultaneous evolution of production technology, storage and distribution of hydrogen fuel cells has been assessed.

Health and safety in the construction : subject pending to be included in the curriculum of architecture in Spain

The art of construction is a risky activity that directly affects the life and physical integrity of persons. Since the approval of Law 31/1995, of November 8, Prevention of Occupational Risks was the first legislation that established the current basis in all sectors and then transposed into Spanish law Directive 92/57/CEE called Royal Decree 1627/1997 of October 24, on minimum safety and health dispositions in construction works, measures have been proposed to develop a mixed body of scientific literature composed of researchers and professionals in the field of occupational safety and health, but even today there is still no clear and firm proposal, showing a lack of awareness in the occupational risk prevention and, therefore, a consolidation of the culture of prevention in society. Therefore, the technicians, who make up the building process, can incur in very high responsibilities, such as: Author of the project, Coordinator of Safety and Health during the preparation of the project and during the execution of works, Site Management: Site Manager. This involves the immediate creation of a general training in prevention for all architects starting when still studying, as well as specific training, appropriate and complementary to all the architects that will be devoted to the specialty of occupational safety and health in construction works. That is, first, we must make the responsible bodies aware of the urgent need to integrate risk prevention in the curricula of architecture and later in the continuing education of the profession. It is necessary that our teaching must conform to the laws on safety and health, due to the fact that the law recognizes our academic degrees and professional qualifications to perform functions in that area

Evolución y crisis de la región metropolitana de Madrid 1985-2007. Análisis de las diversas perspectivas para la transformación del gobierno urbano: una revisión crítica del planeamiento

La Región Metropolitana de Madrid (RMM) ha sufrido una gran transformación urbana en el periodo 1985-2007, en el cual ha crecido la población, ha crecido fuertemente el cuerpo físico, pero sobre todo han crecido su coste y su consumo, lo que supone que se ha vuelto más insostenible. Para tratar de comprender esta evolución asimétrica se ensayan sucesivos modelos que tratan de explicar la transformación de la realidad a través de la articulación de las formas de poder y sus políticas asociadas dentro del contexto local-metropolitano. Si se compara la transformación urbana en el periodo 1985-2007 respecto a la registrada durante el desarrollismo previo al presente periodo democrático, se encuentran similitudes, como el amplio consumo de suelo, pero el modelo desarrollista se inscribe en otras lógicas y tiene otros parámetros de contexto y es congruente ya que las últimas décadas del Régimen Franquista se caracterizan por un importantísimo aumento poblacional que se correspondía con el fuerte crecimiento industrial de la RMM. Esa congruencia relativa se pierde en el periodo estudiado, a pesar de que en 1985, se aprueba el Plan General de Ordenación Urbana de Madrid centrado en la ciudad existente y con un crecimiento contenido, y que puede considerarse un modelo abortado. Tras numerosas transformaciones políticas, económicas, sociales y urbanísticas se llega a una situación opuesta a la prevista en el citado Plan. Más de veinte años después, en 2007, se presentan no solo síntomas de agotamiento del modelo finalmente adoptado, sino su quiebra dramática tanto en su dimensión inmobiliario-financiera como del espacio del bienestar. Es precisamente la supresión de los mecanismos de regulación lo que ha caracterizado la evolución de los modelos urbanos, en correspondencia con la desregulación de las actividades económicas y de los flujos de capital propios del modelo "neoliberal". La actual crisis financiera internacional, en especial en algunos países periféricos europeos como España, ha demostrado cómo las políticas económicas que se han llevado a cabo, fuera de toda regulación, han resultado insostenibles. Pero no se trata solo de una crisis económica. En el caso español, de todas las dimensiones de la crisis, destaca la dimensión urbana, o el auge y caída del ciclo inmobiliario, debido a la urbanización intensiva del territorio en relación con el circuito secundario de la acumulación capitalista, habiendo tenido especial incidencia en algunos territorios como la RMM. En la Región Metropolitana de Madrid la situación actual es de crisis urbana, causada principalmente por el divorcio entre las necesidades y la producción de ciudad, pues no se ha basado el crecimiento en la creación de nuevos hogares, u otras cuestiones demográficas, sino en la acumulación de capital a través del crecimiento de la ciudad. Además, dicho crecimiento está conformado por una expansión urbana descontrolada, con mayores requerimientos energéticos que el modelo compacto y complejo tradicional, lo que unido a la escala de los procesos, supone un sistema urbano progresivamente ineficiente. El caso de la RMM resulta paradigmático, ya que la región ha desempeñado un papel como laboratorio de nuevas formas de gobierno y planificación que han dado un mayor protagonismo al espacio, que ha entrado en las dinámicas centrales principalmente por el apoyo al crecimiento físico, a la vez que han confluido circunstancias específicas, como un nuevo impulso al centralismo, lo que ha potenciado ciertas políticas, como considerar la ciudad como motor de crecimiento económico y de competitividad en el concierto europeo y mundial de ciudades. El estudio del papel de la planificación y sus crisis en la sucesión de los modelos, muestra su función nuclear en la propia constitución de estos —es parte fundamental de su aparato de regulación— y su valor no solo para poder entender el periodo, sino para poder proyectar otro futuro urbano. Este enfoque conduce a establecer la relación del planeamiento con las diferentes crisis económicas en el periodo de estudio lo que permite diferenciar tres momentos de dicha relación: la planificación urbanística austera bajo la influencia de la crisis fordista, la salida de la crisis a través de la imposición de un modelo urbano basado en el sobreproducción de espacio urbano, y la entrada en una crisis inmobiliaria y de financiarización en relación a la adopción de un modelo multidimensionalmente insostenible. El análisis de este periodo es la base para apuntar perspectivas que permitan transformar el gobierno urbano hacia un modelo urbano más deseable, o mejor aún, otros futuros posibles, que se enmarcan dentro de la alternativa principal que supone la sostenibilidad. Madrid's Metropolitan Region (MMR) has undergone a major urban transformation in the period 1985-2007, where the population has grown up, the built environment has grown strongly, but mostly its cost and consumption have grown, which means that it has become unsustainable. To try to understand this evolution successive asymmetric models are tested in order to explain the transformation of reality through the articulation of forms of power and its associated policies in that localmetropolitan context. Comparing the urban transformation in the period 1985-2007 to the existing during developmentalism in the current predemocratic period, both have similarities in terms of land consumption, but the previous developmentalism model is part of another logics and has got other context parameters. It is consistent since the last decades of the Franco Regime was characterized by an important population increase that corresponded to strong industrial growth of the MMR. This relative consistency is lost during the study period, although in 1985, with the approval of the Master Plan of Madrid that was focused on the existing city, with a limited growth, and it may be considered an interrupted model. After numerous political, economic, social and urban changes, there is the opposite situation to that foresight under that Plan. Over twenty years later, in 2007, there are not only signs of exhaustion of the model which was finally adopted, but also its dramatic collapse in both real estate and financial dimension of space as well. The urban transformation under analysis has relaunched the hegemony of the sectors that rule the growth of the Madrid's Metropolitan Region and it is supported by decision making and financing of the different administrations with the passivity of the social stakeholders and citizens. This has meant the removal of regulatory mechanisms that have characterized the evolution of urban models, corresponding to the deregulation of economic activities and capital flows according to "neoliberal" model. The current international financial crisis, especially in some European peripheral countries like Spain, has shown how economic policies that have been carried out, without any regulation, have proven unsustainable. But it is not only an economic crisis. In the Spanish case, of all the dimensions of the crisis, it is the urban dimension that is highlighted, or the rise and fall of real estate cycle, due to intensive urbanization of the territory in relation to the secondary circuit of capital accumulation, having had a particular impact in some territories such as the Madrid's Metropolitan Region. In Madrid's Metropolitan Region there is the current situation of urban crisis, mainly caused by the divorce between needs and the city (space) production, because no growth has been based on creating new homes, or other demographic issues, but in the capital accumulation through growth of the city. Furthermore, this growth is made up of urban sprawl, with higher energy requirements than the traditional compact and complex one, which together with the scale of processes, is increasingly an inefficient urban system. The case of Madrid's Metropolitan Region is paradigmatic, since the region has played a role as a laboratory for new forms of governance and planning have given a greater role to space, which has entered the core dynamics supported mainly by physical growth, while specific circumstances have come together as a new impulse to centralization. This has promoted policies such as considering the city as an engine of economic growth and competitiveness in the international and the European hierarchy of cities. The study of the role of planning and crisis in the succession of models, shows its nuclear role in the constitution of these models is a fundamental part of its regulatory apparatus- and also its value not only to understand the period, but to anticipate to other urban future. This approach leads to establish the relationship of planning with the various crises in the study period, allowing three different moments of that relationship: the austere urban planning under the influence of Fordist crisis, the output of the crisis through imposition of an urban model based on the overproduction of urban space, and entry into a housing crisis and financialisation in relation to the adoption of a multi-dimensionally unsustainable model. The analysis of this period is the basis for targeting prospects that translate urban governance towards a more desirable urban model, or better yet, other possible futures, which are part of the main alternative that is sustainability.

Diseño de un modelo de riesgo integral de incendios forestales mediante técnicas multicriterio y su automatización en sistemas de información geográfica : una aplicación en la Comunidad Valenciana

Los incendios forestales son la principal causa de mortalidad de árboles en la Europa mediterránea y constituyen la amenaza más seria para los ecosistemas forestales españoles. En la Comunidad Valenciana, diariamente se despliega cerca de un centenar de vehículos de vigilancia, cuya distribución se apoya, fundamentalmente, en un índice de riesgo de incendios calculado en función de las condiciones meteorológicas. La tesis se centra en el diseño y validación de un nuevo índice de riesgo integrado de incendios, especialmente adaptado a la región mediterránea y que facilite el proceso de toma de decisiones en la distribución diaria de los medios de vigilancia contra incendios forestales. El índice adopta el enfoque de riesgo integrado introducido en la última década y que incluye dos componentes de riesgo: el peligro de ignición y la vulnerabilidad. El primero representa la probabilidad de que se inicie un fuego y el peligro potencial para que se propague, mientras que la vulnerabilidad tiene en cuenta las características del territorio y los efectos potenciales del fuego sobre el mismo. Para el cálculo del peligro potencial se han identificado indicadores relativos a los agentes naturales y humanos causantes de incendios, la ocurrencia histórica y el estado de los combustibles, extremo muy relacionado con la meteorología y las especies. En cuanto a la vulnerabilidad se han empleado indicadores representativos de los efectos potenciales del incendio (comportamiento del fuego, infraestructuras de defensa), como de las características del terreno (valor, capacidad de regeneración…). Todos estos indicadores constituyen una estructura jerárquica en la que, siguiendo las recomendaciones de la Comisión europea para índices de riesgo de incendios, se han incluido indicadores representativos del riesgo a corto plazo y a largo plazo. El cálculo del valor final del índice se ha llevado a cabo mediante la progresiva agregación de los componentes que forman cada uno de los niveles de la estructura jerárquica del índice y su integración final. Puesto que las técnicas de decisión multicriterio están especialmente orientadas a tratar con problemas basados en estructuras jerárquicas, se ha aplicado el método TOPSIS para obtener la integración final del modelo. Se ha introducido en el modelo la opinión de los expertos, mediante la ponderación de cada uno de los componentes del índice. Se ha utilizado el método AHP, para obtener las ponderaciones de cada experto y su integración en un único peso por cada indicador. Para la validación del índice se han empleado los modelos de Ecuaciones de Estimación Generalizadas, que tienen en cuenta posibles respuestas correlacionadas. Para llevarla a cabo se emplearon los datos de oficiales de incendios ocurridos durante el período 1994 al 2003, referenciados a una cuadrícula de 10x10 km empleando la ocurrencia de incendios y su superficie, como variables dependientes. Los resultados de la validación muestran un buen funcionamiento del subíndice de peligro de ocurrencia con un alto grado de correlación entre el subíndice y la ocurrencia, un buen ajuste del modelo logístico y un buen poder discriminante. Por su parte, el subíndice de vulnerabilidad no ha presentado una correlación significativa entre sus valores y la superficie de los incendios, lo que no descarta su validez, ya que algunos de sus componentes tienen un carácter subjetivo, independiente de la superficie incendiada. En general el índice presenta un buen funcionamiento para la distribución de los medios de vigilancia en función del peligro de inicio. No obstante, se identifican y discuten nuevas líneas de investigación que podrían conducir a una mejora del ajuste global del índice. En concreto se plantea la necesidad de estudiar más profundamente la aparente correlación que existe en la provincia de Valencia entre la superficie forestal que ocupa cada cuadrícula de 10 km del territorio y su riesgo de incendios y que parece que a menor superficie forestal, mayor riesgo de incendio. Otros aspectos a investigar son la sensibilidad de los pesos de cada componente o la introducción de factores relativos a los medios potenciales de extinción en el subíndice de vulnerabilidad. Summary Forest fires are the main cause of tree mortality in Mediterranean Europe and the most serious threat to the Spanisf forest. In the Spanish autonomous region of Valencia, forest administration deploys a mobile fleet of 100 surveillance vehicles in forest land whose allocation is based on meteorological index of wildlandfire risk. This thesis is focused on the design and validation of a new Integrated Wildland Fire Risk Index proposed to efficient allocation of vehicles and specially adapted to the Mediterranean conditions. Following the approaches of integrated risk developed last decade, the index includes two risk components: Wildland Fire Danger and Vulnerability. The former represents the probability a fire ignites and the potential hazard of fire propagation or spread danger, while vulnerability accounts for characteristics of the land and potential effects of fire. To calculate the Wildland Fire Danger, indicators of ignition and spread danger have been identified, including human and natural occurrence agents, fuel conditions, historical occurrence and spread rate. Regarding vulnerability se han empleado indicadores representativos de los efectos potenciales del incendio (comportamiento del fuego, infraestructurasd de defensa), como de las características del terreno (valor, capacidad de regeneración…). These indicators make up the hierarchical structure for the index, which, following the criteria of the European Commission both short and long-term indicators have been included. Integration consists of the progressive aggregation of the components that make up every level in risk the index and, after that, the integration of these levels to obtain a unique value for the index. As Munticriteria methods are oriented to deal with hierarchically structured problems and with situations in which conflicting goals prevail, TOPSIS method is used in the integration of components. Multicriteria methods were also used to incorporate expert opinion in weighting of indicators and to carry out the aggregation process into the final index. The Analytic Hierarchy Process method was used to aggregate experts' opinions on each component into a single value. Generalized Estimation Equations, which account for possible correlated responses, were used to validate the index. Historical records of daily occurrence for the period from 1994 to 2003, referred to a 10x10-km-grid cell, as well as the extent of the fires were the dependant variables. The results of validation showed good Wildland Fire Danger component performance, with high correlation degree between Danger and occurrence, a good fit of the logistic model used and a good discrimination power. The vulnerability component has not showed a significant correlation between their values and surface fires, which does not mean the index is not valid, because of the subjective character of some of its components, independent of the surface of the fires. Overall, the index could be used to optimize the preventing resources allocation. Nevertheless, new researching lines are identified and discussed to improve the overall performance of the index. More specifically the need of study the inverse relationship between the value of the wildfire Fire Danger component and the forested surface of each 10 - km cell is set out. Other points to be researched are the sensitivity of the index component´s weight and the possibility of taking into account indicators related to fire fighting resources to make up the vulnerability component.

Understanding HCI policy in Spain in the context of acces

Spain pioneered policies related to disability and accessibility, especially in the physical environment. The first major piece of legislation was Act 13/1982 on the Social Integration of People with Disabilities. The law was published just a few years after the reinstitution of democracy in Spain in 1977 and the approval of the Spanish Constitution in 1978. Act 13/1982 is a general law that applies accessibility to social services and education, as well as to workplace and physical accessibility. This law targeted first and foremost the social integration of people with disabilities, and it was a significant success, especially in the field of employment, as it made it mandatory for private companies and public administrations to employ a certain percentage of persons with disabilities. This greatly increased the employability of people with disabilities, as highlighted in a document celebrating 30 years of Act 13/1982. Over the past 20 years, policy makers have also focused on accessibility to information and communication technologies (ICT), developing first the national computing accessibility standards and then specialized legislation. Initially, Spanish activities were mostly national but have now gained an international dimension. All these initiatives are strongly related to the discipline of human-computer interaction, as the key component of an accessible system is its user interface.

Dominance Measuring Method Performance under Incomplete Information about Weights.

In multi-attribute utility theory, it is often not easy to elicit precise values for the scaling weights representing the relative importance of criteria. A very widespread approach is to gather incomplete information. A recent approach for dealing with such situations is to use information about each alternative?s intensity of dominance, known as dominance measuring methods. Different dominancemeasuring methods have been proposed, and simulation studies have been carried out to compare these methods with each other and with other approaches but only when ordinal information about weights is available. In this paper, we useMonte Carlo simulation techniques to analyse the performance of and adapt such methods to deal with weight intervals, weights fitting independent normal probability distributions orweights represented by fuzzy numbers.Moreover, dominance measuringmethod performance is also compared with a widely used methodology dealing with incomplete information on weights, the stochastic multicriteria acceptability analysis (SMAA). SMAA is based on exploring the weight space to describe the evaluations that would make each alternative the preferred one.

This study discusses the optimisation of a selectiv e and differential medium which would facilitate the isolation of Schizosaccharomyces (a genus with a low incidence compared to other microorganisms) to select individuals from this genus for industrial purposes, especially in light of the recent approval of the use of yeasts from this genus in the wine industry by the International Organisation of Vine and Wine, or to detect the presence of such yeasts, for those many authors who consider them food spoilers. To this end, we studied various selective differential agents based on the main thephysiological characteristics of this species, such as its high resistance to high concentrations of sugar, sulfur dioxide, sorbic acid, benzoic acid, acetic acid or malo ethanolic fermentation. This selective medium is based on the resistance of the genus to the antibiotic actidione and its high resistance to inhibitory agents such as benzoic acid compared to possible microorganisms which can give rise to false positive results. Malic acid was used as a differential fact or due to the ability of this genus to metabolise it to ethanol, which allows detecting of the degradation of this compound. Lastly, the medium was successfully used to isolate strains of Schizosaccharomyces pombe from honey.

Preference intensity in MCDM when an additive utility function represents DM preferences

We propose a new method for ranking alternatives in multicriteria decision-making problems when there is imprecision concerning the alternative performances, component utility functions and weights. We assume decision maker?s preferences are represented by an additive multiattribute utility function, in which weights can be modeled by independent normal variables, fuzzy numbers, value intervals or by an ordinal relation. The approaches are based on dominance measures or exploring the weight space in order to describe which ratings would make each alternative the preferred one. On the one hand, the approaches based on dominance measures compute the minimum utility difference among pairs of alternatives. Then, they compute a measure by which to rank the alternatives. On the other hand, the approaches based on exploring the weight space compute confidence factors describing the reliability of the analysis. These methods are compared using Monte Carlo simulation.

La videovigilancia : tecnologías actuales y aspectos sociopolíticos

En este Proyecto de fin de carrera titulado: LA VÍDEOVIGILANCIA: TECNOLOGÍAS ACTUALES Y ASPECTOS SOCIOPOLÍTICOS, tiene como objetivo hacer un estudio en los sistemas de Vídeovigilancia basado en cámaras-IP, con fines de seguridad, control o supervisión. Nos basaremos en exponer los sistemas Vídeovigilancia basados en cámara-IP actuales de ultima generación, cuya principal virtud de estos sistemas, es la comunicación con otros lugares, o espacios públicos como privados y poder visualizar tanto en vivo como en diferido lo que este pasando en ese lugar y en ese momento o haya pasado a través del protocolo de comunicación-IP. Se explicara desde el más básico al más complejo sistema de videovigilancia-IP, también explicaremos su puesta en practica mediante los múltiples interconexiones que estos conlleven. Llegando a este punto, se nos plantea las siguientes cuestiones que da origen a este PFC. Estos sistemas de Vídeovigilancia-IP, captan las imágenes por medio de las cámaras-IP, proporcionando su facilidad tanto de visionado/grabacion, como de control, ya que no es necesario estar presente e interactuando con otros sistemas digitales de diverso índole actuales, gracias al protocolo-IP. Estos sistemas-IP, tienen su puesta en práctica mediante las instalaciones requeridas ,estas podrán ser sencillas o muy complejas de todos los sistemas-IP. Debido al gran aumento masivo, las tecnologías actuales de diverso índole de cámaras-IP en materia de la vídeovigilancia en lugares públicos, y privados en nuestra sociedad actual, lo hace un medio particularmente invasivo y por ello resulta necesario tanto la concurrencia de condiciones que legitimen los tratamientos de datos de personas identificables, como la definición de los principios y garantías que deban aplicarse ya que estas, repercutirán sobre los derechos de las personas, lo que obligara a fijar ciertas garantías. Se nos plantea los casos en los que la captación y/o tratamiento de imágenes con fines de Vídeovigilancia que pertenezcan a personas identificadas o identificables, ha obligado a España, y según dispuesto por la Directiva 95/46/CE del Parlamento Europeo, a regularizar esta situación mediante la Ley Orgánica de Protección de Datos (LOPD) 15/1999 de 13 de diciembre, bajo los procedimientos del Estado español en materia sociopolítica, y dando vigor a esta ley, mediante la aprobación de la Instrucción 1/2006 de 8 de noviembre de 2006, cuyo máximo organismo es la Agencia española de Protección de Datos (AGPD). Una vez planteada la motivación y justificación del proyecto, se derivan unos objetivos a cumplir con la realización del mismo. Los objetivos del proyecto se pueden diferenciar en dos clases principalmente. Los objetivos principales y objetivos secundarios. Los objetivos principales de este PFC, nacen directamente de las necesidades planteadas originalmente en materia de Vídeovigilancia, tanto tecnológicamente basado en las cámaras-IP en la captación y/o tratamiento de imágenes, así como sociopolíticamente donde trataremos de describirlo mediante las indicaciones y criterios con casos prácticos y de cómo deben de aplicarse según la instrucción 1/2006 mediante la LOPD en materia de Vídeovigilancia, en cuanto a la protección de datos que puedan repercutir sobre el derecho de las personas. Por otra parte los objetivos secundarios, son la extensión del objetivo primario y son de orden cuantificador en este PFC, dando una explicación más exhaustiva del objetivo principal. ABSTRACT In this final year project, entitled: THE VIDEOSURVEILLANCE: CURRENT TECHNOLOGIES AND POLITICALSOCIALS ASPECTS, aims to make a study of video surveillance systems based on IP cameras, for security, control or supervision. We will rely on to expose the camera based video surveillance systems IP-current last generation, whose main virtue of these systems, is communication with other places, or public and private spaces and to view both live and time so this happening in that place and at that time or passed through-IP communication protocol. He explained from the most basic to the most complex-IP video surveillance system, also explain its implementation into practice through multiple interconnections that these entail. Arriving at this point, we face the following issues which gave rise to this PFC. These IP-video surveillance systems, captured images through IP-cameras, providing both ease of viewing / recording, as a control, since it is not necessary to be present and interacting with other digital systems such diverse today, thanks IP-protocol. These systems-IP, have their implementation through the facilities required, these can be simple or very complex all-IP video surveillance systems. Due to the large increase in mass, current technologies of different kinds of IP cameras for video surveillance in public places, and private in our society, it makes a particularly invasive and therefore attendance is necessary both conditions that legitimize data processing of identifiable people, as the definition of the principles and safeguards to be applied as these will impact on the rights of the people, which forced to set certain guarantees. We face those cases in which the uptake and / or image processing video surveillance purposes belonging to identified or identifiable, has forced Spain, and as required by Directive 95/46/EC of the European Parliament, to regularize this situation by the Organic Law on Data Protection (LOPD) 15/1999 of December 13, under the procedures of the Spanish State in sociopolitical, and giving effect to this Act, with the approval of the Instruction 1/2006 of 8 November 2006, the governing body is the Spanish Agency for Data Protection (AGPD). Once raised the motivation and justification for the project, resulting in meeting targets to achieve the same. Project objectives can be differentiated into two main classes, the main objectives and secondary objectives: The main objectives of this PFC, born directly from requirements originally raised for capturing both technologically imaging me and try to describe where sociopolitically, the details and criteria as case studies and should be applied according to the instruction 1 / 2006 by the LOPD on video surveillance system in terms of data protection that could impact on the right people. Moreover the secondary objectives are the extension of the primary and are of a quantifier in this PFC, giving a fuller explanation of the main objective.

Potencial de la producción de bioelectricidad de las Comarcas Agrarias de la Comunidad de Madrid en base a centeno y triticale

En el presente trabajo se estudia la producción potencial de biomasa procedente de los cultivos de centeno y triticale en las seis comarcas agrarias de la Comunidad de Madrid (CM) y la posibilidad de su aplicación a la producción de bioelectricidad en cada una de ellas. En primer lugar se realiza un estudio bibliográfico de la situación actual de la bioelectricidad. Uno de los principales datos a tener en cuenta es que en el PER 2011- 2020 se estima que el total de potencia eléctrica instalada a partir de biomasa en España en el año 2020 sea de 1.350 MW, unas dos veces y media la existente a finales de 2010. Además, se comenta el estado de la incentivación del uso de biomasa de cultivos energéticos para producción de electricidad, la cual se regula actualmente según el Real Decreto-ley 9/2013, de 12 de Julio, por el que se adoptaron medidas urgentes para garantizar la estabilidad financiera del sistema eléctrico, y se consideran los criterios de sostenibilidad en el uso de biocombustibles sólidos. Se realiza una caracterización de las seis comarcas agrarias que forman la Comunidad Autónoma de Madrid: Área Metropolitana, Campiña, Guadarrama, Lozoya- Somosierra, Sur-Occidental y Vegas, la cual consta de dos partes: una descripción de la climatología y otra de la distribución de la superficie dedicada a barbecho y cultivos herbáceos. Se hace una recopilación bibliográfica de los modelos de simulación más representativos de crecimiento de los cultivos (CERES y Cereal YES), así como de ensayos realizados con los cultivos de centeno y triticale para la producción de biomasa y de estudios efectuados mediante herramientas GIS y técnicas de análisis multicriterio para la ubicación de centrales de bioelectricidad y el estudio de la logística de la biomasa. Se propone un modelo de simulación de la productividad de biomasa de centeno y de triticale para la CM, que resulta de la combinación de un modelo de producción de grano en base a datos climatológicos y a la relación biomasa/grano media de ambos cultivos obtenida en una experiencia previa. Los modelos obtenidos responden a las siguientes ecuaciones (siendo TN = temperatura media normalizada a 9,9 ºC y PN = precipitación acumulada normalizada a 496,7 mm): - Producción biomasa centeno (t m.s./ha) = 2,785 * [1,078 * ln(TN + 2*PN) + 2,3256] - Producción biomasa triticale (t m.s./ha) = 2,595 * [2,4495 * ln(TN + 2*PN) + 2,6103] Posteriormente, aplicando los modelos desarrollados, se cuantifica el potencial de producción de biomasa de centeno y triticale en las distintas comarcas agrarias de la CM en cada uno de los escenarios establecidos, que se consideran según el uso de la superficie de barbecho de secano disponible (25%, 50%, 75% y 100%). Las producciones potenciales de biomasa, que se podrían alcanzar en la CM utilizando el 100% de la superficie de barbecho de secano, en base a los cultivos de centeno y triticale, se estimaron en 169.710,72 - 149.811,59 - 140.217,54 - 101.583,01 - 26.961,88 y 1.886,40 t anuales para las comarcas de Campiña - Vegas, Sur - Occidental - Área Metropolitana - Lozoya-Somosierra y Guadarrama, respectivamente. Se realiza un análisis multicriterio basado en la programación de compromiso para definir las comarcas agrarias con mejores características para la ubicación de centrales de bioelectricidad en base a los criterios de potencial de biomasa, infraestructura eléctrica, red de carreteras, espacios protegidos y superficie de núcleos urbanos. Al efectuar el análisis multicriterio, se obtiene la siguiente ordenación jerárquica en base a los criterios establecidos: Campiña, Sur Occidental, Vegas, Área Metropolitana, Lozoya-Somosierra y Guadarrama. Mediante la utilización de técnicas GIS se estudia la localización más conveniente de una central de bioelectricidad de 2,2 MW en cada una de las comarcas agrarias y según el uso de la superficie de barbecho de secano disponible (25%, 50%, 75% y 100%), siempre que exista potencial suficiente. Para el caso de la biomasa de centeno y de triticale en base seca se considera un PCI de 3500 kcal/kg, por lo que se necesitarán como mínimo 17.298,28 toneladas para satisfacer las necesidades de cada una de las centrales de 2,2 MW. Se analiza el potencial máximo de bioelectricidad en cada una de las comarcas agrarias en base a los cultivos de centeno y triticale como productores de biomasa. Según se considere el 25% o el 100% del barbecho de secano para producción de biomasa, la potencia máxima de bioelectricidad que se podría instalar en cada una de las comarcas agrarias variaría entre 5,4 y 21,58 MW en la comarca Campiña, entre 4,76 y 19,05 MW en la comarca Vegas, entre 4,46 y 17,83 MW en la comarca Sur Occidental, entre 3,23 y 12,92 MW en la comarca Área Metropolitana, entre 0,86 y 3,43 MW en la comarca Lozoya Somosierra y entre 0,06 y 0,24 MW en la comarca Guadarrama. La potencia total que se podría instalar en la CM a partir de la biomasa de centeno y triticale podría variar entre 18,76 y 75,06 MW según que se utilice el 25% o el 100% de las tierras de barbecho de secano para su cultivo. ABSTRACT In this work is studied the potential biomass production from rye and triticale crops in the six Madrid Community (MC) agricultural regions and the possibility of its application to the bioelectricity production in each of them. First is performed a bibliographical study of the current situation of bioelectricity. One of the main elements to be considered is that in the PER 2011-2020 is estimated that the total installed electric power from biomass in Spain in 2020 was 1.350 MW, about two and a half times as at end 2010. Also is discussed the status of enhancing the use of biomass energy crops for electricity production, which is currently regulated according to the Real Decreto-ley 9/2013, of July 12, by which urgent measures were adopted to ensure financial stability of the electrical system, and there are considered the sustainability criteria in the use of solid biofuels. A characterization of the six Madrid Community agricultural regions is carried out: Area Metropolitana, Campiña, Guadarrama, Lozoya-Somosierra, Sur-Occidental and Vegas, which consists of two parts: a description of the climatology and another about the distribution of the area under fallow and arable crops. It makes a bibliographic compilation of the most representative crop growth simulation models (CERES and Cereal YES), as well as trials carried out with rye and triticale crops for biomass production and studies conducted by GIS tools and techniques multicriteria analysis for the location of bioelectricity centrals and the study of the logistics of biomass. Is proposed a biomass productivity simulation model for rye and triticale for MC that results from the combination of grain production model based on climatological data and the average relative biomass/grain of both crops obtained in a prior experience. The models obtained correspond to the following equations (where TN = normalized average temperature and PN = normalized accumulated precipitation): - Production rye biomass (t d.m./ha) = 2.785 * [1.078 * ln (TN + 2*PN) + 2.3256] - Production triticale biomass (t d.m./ha) = 2,595 * [2.4495 * ln (TN + 2*PN) + 2.6103] Subsequently, applying the developed models, the biomass potential of the MC agricultural regions is quantified in each of the scenarios established, which are considered as the use of dry fallow area available (25%, 50%, 75 % and 100%). The potential biomass production that can be achieved within the MC using 100% of the rainfed fallow area based on rye and triticale crops, were estimated at 169.710,72 - 149.811,59 - 140.217,54 - 101.583,01 - 26.961,88 and 1.886,40 t annual for the regions of Campiña, Vegas, Sur Occidental, Area Metropolitana, Lozoya- Somosierra and Guadarrama, respectively. A multicriteria analysis is performed, based on compromise programming to define the agricultural regions with better features for the location of bioelectricity centrals, on the basis of biomass potential, electrical infrastructure, road network, protected areas and urban area criteria. Upon multicriteria analysis, is obtained the following hierarchical order based on criteria: Campiña, Sur Occidental, Vegas, Area Metropolitana, Lozoya-Somosierra and Guadarrama. Likewise, through the use of GIS techniques, the most suitable location for a 2,2 MW bioelectricity plant is studied in each of the agricultural regions and according to the use of dry fallow area available (25%, 50% , 75% and 100%), if there is sufficient potential. In the case of biomass rye and triticale dry basis is considered a PCI of 3500 kcal/kg, so it will take at least 17,298.28 t to satisfy the needs of each plant. Is analyzed the maximum bioelectricity potential on each of the agricultural regions on the basis of the rye and triticale crops as biomass producers. As deemed 25% or 100% dry fallow for biomass, the maximum bioelectricity potential varies between 5,4 and 21,58 MW in the Campiña region, between 4,76 and 19,05 MW in the Vegas region, between 4,46 and 17,83 MW in the Sur Occidental region, between 3,23 and 12,92 MW in the Area Metropolitana region, between 0,86 and 3,43 MW in the Lozoya-Somosierra region and between 0,06 and 0,24 MW in the Guadarrama region. The total power that could be installed in the CM from rye and triticale biomass could vary between 18.76 and 75.06 MW if is used the 25% or 100% of fallow land for rainfed crop.
