Desarrollo metodológico de evaluación y aplicación de la sostenibilidad como base en los modelos educativos, para la evolución e innovación de la enseñanza de la arquitectura: modelo educativo de estudio México y España

La arquitectura y la construcción deben generar un bien común para la sociedad y medio ambiente, los arquitectos tienen la responsabilidad de mitigar muchos efectos negativos que se generan en esta profesión; esto no es posible si los estudiantes egresan con un conocimiento nulo sobre la arquitectura sostenible; por lo que surge la inquietud de desarrollar la presente tesis, con el objetivo de aportar de una forma sutil al desarrollo de la arquitectura compartiendo conocimiento para generar conocimiento, ya que la investigación que a continuación se desarrolla está enfocada al desarrollo de la arquitectura sostenible en el campo de la formación de los estudiantes, donde se pueda enlazar los nuevos requerimientos profesionales planteados desde la sostenibilidad. La formación del arquitecto ha intentado abordar el conocimiento humanístico, técnico, cultural, tecnológico, calculo estructural, instalaciones y construcciones; sin embargo, se ha dejado a un lado lo que abarca la arquitectura sostenible, como calidad de vida, diseño bioclimático, energías renovables, normativas sostenibles, economía viable, emisiones, contaminación y residuos generados, materiales, elementos constructivos sostenibles, mancha urbana, huella ecológica, impacto ambiental y análisis del ciclo de vida, entre otras estrategias o elementos. A través de la investigación científica y profunda que se ha realizado, se busca conformar el conocimiento sistemático que contribuya a la resolución de los problemas de nuestra sociedad, ambiente y educación, con la elaboración de un sistema metodológico de evaluación y aplicación de sostenibilidad en los modelos educativos. Para desarrollar el sistema de evaluación y aplicación, se desarrolla una metodología de investigación donde se justifica la necesidad de la creación de dicho sistema, en base al análisis de la situación actual del medio ambiente y la relación directa con la arquitectura, construcción y conocimientos adquiridos en la formación de los estudiantes de arquitectura, donde se demuestra la importancia de la educación de la arquitectura sostenible en el desarrollo de las sociedades. En base al análisis de metodologías y sistemas que evalúan la sostenibilidad de los edificios y los sistemas que evalúan la educación, se propone uno propio para evaluar las asignaturas de los modelos educativos en base a elementos sostenibles propuestos. La presente investigación se enmarca en una estrategia general de promover la evaluación y aplicación de la sostenibilidad en los modelos educativos de las escuelas de arquitectura a nivel internacional; como caso de estudio se evaluará el plan de estudios llamado Minerva, de la Benemérita Universidad Autónoma de Puebla en México, donde he realizado una estancia de investigación y la Escuela Técnica Superior de Arquitectura de la Universidad Politécnica de Madrid en España, donde he cursado el doctorado. ABSTRACT Architecture and construction must generate a common good for the society and environment, the architects have the responsibility of mitigating many negative effects that are generated in this profession; this is not possible if the students graduate with a void knowledge on the sustainable architecture that is why the concern for developing the present thesis, with the aim to contribute to the development of the architecture sharing knowledge to generate knowledge, seeing as the investigation that later develops is focused on the development of the sustainable architecture in about the student’s professional training, where it could connect the new professional requirements raised from the sustainability. The architect’s professional training has tried to approach the humanistic, technical, cultural, technological knowledge, structural calculation, fittings and constructions; nevertheless, there has been left aside what includes the sustainable architecture, as quality of life, design bioclimatic, renewable energies, sustainable regulations, viable economy, emission, pollution and generated, material residues, constructive sustainable elements, urban spot, ecological fingerprint, environmental impact and analysis of the life cycle, between other strategies or elements. Across the scientific and deep research that has been realized, it reaches to make up the systematic knowledge that he contributes to the resolution of the problems of our society, environment and education, with the production of a methodological system of evaluation and application of sustainability in the educational models. To develop the system of evaluation and application, there is a methodology of research where it justifies itself the need of the creation of the above mentioned system, on the basis of the analysis of the current situation of the environment and the direct relationship with the architecture, construction and knowledge acquired in the architecture student’s education, where there is demonstrated the matter of the education of the sustainable architecture in the development of the companies. Based on the analysis of methodologies and systems that evaluate the sustainability of the buildings and the systems that evaluate the education, there is one own proposes to evaluate the subjects of the educational models on the basis of sustainable proposed elements. The present research places in a general strategy of promoting the evaluation and application of the sustainability in the educational models of the schools of architecture worldwide; since case of study will evaluate the study plan called Minerva, of the Meritorious Autonomous University of It Populates in Mexico, where I have realized a stay of researching and the Technical Top School of Architecture of the Technical University of Madrid in Spain, where the PHD has been done.

Contextualising change through a common strategy

European universities are currently going through a process of change in order to meet the common goals set for higher education by the European Commission. They are revising their educational models to adjust them to the guidelines of the ‘‘Bologna Process’’ and are devising an institutional strategy for its implementation. In practical terms, this means aligning former national degrees and diplomas to standard European Bachelor and Masters degrees and PhD doctorates, by creating acknowledged professional qualification benchmarks that also include adjusted course lengths and contents. This process, in the end, mostly affects academic staff members who have a fundamental role to play in carrying out the pedagogical reforms on the teaching front. Besides presenting a commentary on the institutional approach of one particular technical university in Spain, the purpose of this paper is to propose, from the authors’ point of view as lecturers, a strategy which has the potential to create a favourable atmosphere for carrying out such a reform. The article’s main objective is to highlight a series of action points which may serve to reinforce and advance the main institutional strategy by relying on the powerful influence of its academic staff members

Development of mathematical models to elaborate strategies, select alternatives and development of plans for adaptation of communities to climate change in different geographical areas including costs to implement it.

There is evidence that the climate changes and that now, the change is influenced and accelerated by the CO2 augmentation in atmosphere due to combustion by humans. Such ?Climate change? is on the policy agenda at the global level, with the aim of understanding and reducing its causes and to mitigate its consequences. In most countries and international organisms UNO (e.g. Rio de Janeiro 1992), OECD, EC, etc . . . the efforts and debates have been directed to know the possible causes, to predict the future evolution of some variable conditioners, and trying to make studies to fight against the effects or to delay the negative evolution of such. The Protocol of Kyoto 1997 set international efforts about CO2 emissions, but it was partial and not followed e.g. by USA and China . . . , and in Durban 2011 the ineffectiveness of humanity on such global real challenges was set as evident. Among all that, the elaboration of a global model was not boarded that can help to choose the best alternative between the feasible ones, to elaborate the strategies and to evaluate the costs, and the authors propose to enter in that frame for study. As in all natural, technological and social changes, the best-prepared countries will have the best bear and the more rapid recover. In all the geographic areas the alternative will not be the same one, but the model must help us to make the appropriated decision. It is essential to know those areas that are more sensitive to the negative effects of climate change, the parameters to take into account for its evaluation, and comprehensive plans to deal with it. The objective of this paper is to elaborate a mathematical model support of decisions, which will allow to develop and to evaluate alternatives of adaptation to the climatic change of different communities in Europe and Latin-America, mainly in especially vulnerable areas to the climatic change, considering in them all the intervening factors. The models will consider criteria of physical type (meteorological, edaphic, water resources), of use of the ground (agriculturist, forest, mining, industrial, urban, tourist, cattle dealer), economic (income, costs, benefits, infrastructures), social (population), politician (implementation, legislation), educative (Educational programs, diffusion) and environmental, at the present moment and the future. The intention is to obtain tools for aiding to get a realistic position for these challenges, which are an important part of the future problems of humanity in next decades.

Brain injury MRI simulator based on theoretical models of neuroanatomic damage

In order to improve the body of knowledge about brain injury impairment is essential to develop image database with different types of injuries. This paper proposes a new methodology to model three types of brain injury: stroke, tumor and traumatic brain injury; and implements a system to navigate among simulated MRI studies. These studies can be used on research studies, to validate new processing methods and as an educational tool, to show different types of brain injury and how they affect to neuroanatomic structures.

A Semantic Approach to Problem-Based Learning with Conceptual Models

El aprendizaje basado en problemas se lleva aplicando con éxito durante las últimas tres décadas en un amplio rango de entornos de aprendizaje. Este enfoque educacional consiste en proponer problemas a los estudiantes de forma que puedan aprender sobre un dominio particular mediante el desarrollo de soluciones a dichos problemas. Si esto se aplica al modelado de conocimiento, y en particular al basado en Razonamiento Cualitativo, las soluciones a los problemas pasan a ser modelos que representan el compotamiento del sistema dinámico propuesto. Por lo tanto, la tarea del estudiante en este caso es acercar su modelo inicial (su primer intento de representar el sistema) a los modelos objetivo que proporcionan soluciones al problema, a la vez que adquieren conocimiento sobre el dominio durante el proceso. En esta tesis proponemos KaiSem, un método que usa tecnologías y recursos semánticos para guiar a los estudiantes durante el proceso de modelado, ayudándoles a adquirir tanto conocimiento como sea posible sin la directa supervisión de un profesor. Dado que tanto estudiantes como profesores crean sus modelos de forma independiente, estos tendrán diferentes terminologías y estructuras, dando lugar a un conjunto de modelos altamente heterogéneo. Para lidiar con tal heterogeneidad, proporcionamos una técnica de anclaje semántico para determinar, de forma automática, enlaces entre la terminología libre usada por los estudiantes y algunos vocabularios disponibles en la Web de Datos, facilitando con ello la interoperabilidad y posterior alineación de modelos. Por último, proporcionamos una técnica de feedback semántico para comparar los modelos ya alineados y generar feedback basado en las posibles discrepancias entre ellos. Este feedback es comunicado en forma de sugerencias individualizadas que el estudiante puede utilizar para acercar su modelo a los modelos objetivos en cuanto a su terminología y estructura se refiere. ABSTRACT Problem-based learning has been successfully applied over the last three decades to a diverse range of learning environments. This educational approach consists of posing problems to learners, so they can learn about a particular domain by developing solutions to them. When applied to conceptual modeling, and particularly to Qualitative Reasoning, the solutions to problems are models that represent the behavior of a dynamic system. Therefore, the learner's task is to move from their initial model, as their first attempt to represent the system, to the target models that provide solutions to that problem while acquiring domain knowledge in the process. In this thesis we propose KaiSem, a method for using semantic technologies and resources to scaffold the modeling process, helping the learners to acquire as much domain knowledge as possible without direct supervision from the teacher. Since learners and experts create their models independently, these will have different terminologies and structure, giving rise to a pool of models highly heterogeneous. To deal with such heterogeneity, we provide a semantic grounding technique to automatically determine links between the unrestricted terminology used by learners and some online vocabularies of the Web of Data, thus facilitating the interoperability and later alignment of the models. Lastly, we provide a semantic-based feedback technique to compare the aligned models and generate feedback based on the possible discrepancies. This feedback is communicated in the form of individualized suggestions, which can be used by the learner to bring their model closer in terminology and structure to the target models.

Analytical models for the power subsystem and the attitude control subsystem of a microsatellite

El trabajo realizado en la presente tesis doctoral se debe considerar parte del proyecto UPMSat-2, que se enmarca dentro del ámbito de la tecnología aeroespacial. El UPMSat-2 es un microsatélite (de bajo coste y pequeño tamaño) diseñado, construido, probado e integrado por la Universidad Politécnica de Madrid (España), para fines de demostración tecnológica y educación. El objetivo de la presente tesis doctoral es presentar nuevos modelos analíticos para estudiar la interdependencia energética entre los subsistemas de potencia y de control de actitud de un satélite. En primer lugar, se estudia la simulación del subsistema de potencia de un microsatélite, prestando especial atención a la simulación de la fuente de potencia, esto es, los paneles solares. En la tesis se presentan métodos sencillos pero precisos para simular la producción de energía de los paneles en condiciones ambientales variables a través de su circuito equivalente. Los métodos propuestos para el cálculo de los parámetros del circuito equivalente son explícitos (o al menos, con las variables desacopladas), no iterativos y directos; no se necesitan iteraciones o valores iniciales para calcular los parámetros. La precisión de este método se prueba y se compara con métodos similares de la literatura disponible, demostrando una precisión similar para mayor simplicidad. En segundo lugar, se presenta la simulación del subsistema de control de actitud de un microsatélite, prestando especial atención a la nueva ley de control propuesta. La tesis presenta un nuevo tipo de control magnético es aplicable a la órbita baja terrestre (LEO). La ley de control propuesta es capaz de ajustar la velocidad de rotación del satélite alrededor de su eje principal de inercia máximo o mínimo. Además, en el caso de órbitas de alta inclinación, la ley de control favorece la alineación del eje de rotación con la dirección normal al plano orbital. El algoritmo de control propuesto es simple, sólo se requieren magnetopares como actuadores; sólo se requieren magnetómetros como sensores; no hace falta estimar la velocidad angular; no incluye un modelo de campo magnético de la Tierra; no tiene por qué ser externamente activado con información sobre las características orbitales y permite el rearme automático después de un apagado total del subsistema de control de actitud. La viabilidad teórica de la citada ley de control se demuestra a través de análisis de Monte Carlo. Por último, en términos de producción de energía, se demuestra que la actitud propuesto (en eje principal perpendicular al plano de la órbita, y el satélite que gira alrededor de ella con una velocidad controlada) es muy adecuado para la misión UPMSat-2, ya que permite una área superior de los paneles apuntando hacia el sol cuando se compara con otras actitudes estudiadas. En comparación con el control de actitud anterior propuesto para el UPMSat-2 resulta en un incremento de 25% en la potencia disponible. Además, la actitud propuesto mostró mejoras significativas, en comparación con otros, en términos de control térmico, como la tasa de rotación angular por satélite puede seleccionarse para conseguir una homogeneización de la temperatura más alta que apunta satélite y la antena. ABSTRACT The work carried out in the present doctoral dissertation should be considered part of the UPMSat-2 project, falling within the scope of the aerospace technology. The UPMSat-2 is a microsatellite (low cost and small size) designed, constructed integrated and tested for educational and technology demonstration purposes at the Universidad Politécnica de Madrid (Spain). The aim of the present doctoral dissertation is to present new analytical models to study the energy interdependence between the power and the attitude control subsystems of a satellite. First, the simulation of the power subsystem of a microsatellite is studied, paying particular attention to the simulation of the power supply, i.e. the solar panels. Simple but accurate methods for simulate the power production under variable ambient conditions using its equivalent circuit are presented. The proposed methods for calculate the equivalent circuit parameters are explicit (or at least, with decoupled variables), non-iterative and straight forward; no iterations or initial values for the parameters are needed. The accuracy of this method is tested and compared with similar methods from the available literature demonstrating similar precision but higher simplicity. Second, the simulation of the control subsystem of a microsatellite is presented, paying particular attention to the new control law proposed. A new type of magnetic control applied to Low Earth Orbit (LEO) satellites has been presented. The proposed control law is able to set the satellite rotation speed around its maximum or minimum inertia principal axis. Besides, the proposed control law favors the alignment of this axis with the normal direction to the orbital plane for high inclination orbits. The proposed control algorithm is simples, only magnetorquers are required as actuators; only magnetometers are required as sensors; no estimation of the angular velocity is needed; it does not include an in-orbit Earth magnetic field model; it does not need to be externally activated with information about the orbital characteristics and it allows automatic reset after a total shutdown of attitude control subsystem. The theoretical viability of the control law is demonstrated through Monte Carlo analysis. Finally, in terms of power production, it is demonstrated that the proposed attitude (on principal axis perpendicular to the orbit plane, and the satellite rotating around it with a controlled rate) is quite suitable for the UPMSat-2 mission, as it allows a higher area of the panels pointing towards the sun when compared to other studied attitudes. Compared with the previous attitude control proposed for the UPMSat-2 it results in a 25% increment in available power. Besides, the proposed attitude showed significant improvements, when compared to others, in terms of thermal control, as the satellite angular rotation rate can be selected to achieve a higher temperature homogenization of the satellite and antenna pointing.
