Enseñanza (y aprendizaje) virtual de Geología por parte del alumno=Virtual education (and learning) of Geology by students

Una de las maneras más efectivas para asentar conocimientos se produce cuando, además de realizar un aprendizaje práctico, se intentan transmitir a otra persona. De hecho, los alumnos muchas veces prestan más atención a sus compañeros que al profesor. En la E.T.S.I. Minas de Madrid se ha llevado a cabo un programa de innovación educativa en asignaturas relacionadas con la Geología mediante nuevas tecnologías para mejorar el aprendizaje basado en el trabajo práctico personal del alumno, con la realización de vídeos en el medio físico (campo) en los que explican los aspectos geológicos visibles a diferentes escalas. Estos vídeos se han subido a las plataformas “moodle”, “facebook” y canal “youtube” donde compañeros, alumnos de otras Universidades y personas interesadas pueden consultarlos. De esta manera se pretende que, además de adquirir conocimientos geológicos, los alumnos adquieren el hábito de expresarse en público con un lenguaje técnico. Los alumnos manifestaron su satisfacción por esta actividad, aunque idea del rodaje de vídeos no resultó inicialmente muy popular. Se ha observado una mejora en las calificaciones, así como un incremento de la motivación. De hecho, los estudiantes manifestaron haber adquirido, además de los conceptos geológicos, seguridad a la hora de expresarse en público. Palabras clave: innovación educativa, nuevas tecnologías (TIC), Geología Abstract- Knowledge is gained by practice, but one of the most effective ways is when one tries to transmit it to others. Likewise, students pay more attention to their classmates than to teachers. In the Geological Engineering Department of the Madrid School of Mines, we have run an educational innovation program in courses related to Geology using new technologies (ITC) in order to increase the acquisition of geological knowledge. This program is designed mainly on the basis of individual and group work with video recordings in the field in which students explain geological concepts at various scales. These videos have been uploaded to the “Moodle”, “Facebook” and “YouTube” channel of the Madrid School of Mines, where other students from the same university or elsewhere can view them. Students acquire geological knowledge and the ability to address the general public using technical language. The realization of these videos has been warmly welcomed by students. Notably, they show increased motivation, accompanied by an improvement in grades, although at the beginning this program was not very popular because of student insecurity. Students have expressed that they learnt geological concepts but also gained confidence in public speaking using technical language

Development of a method of assessment of the problem-solving competence at the technical University of Madrid.

The competence evaluation promoted by the European High Education Area entails a very important methodological change that requires guiding support to help lecturers carry out this new and complex task. In this regard, the Technical University of Madrid (UPM, by its Spanish acronym) has financed a series of coordinated projects with the objective of developing a model for teaching and evaluating core competences and providing support to lecturers. This paper deals with the problem-solving competence. The first step has been to elaborate a guide for teachers to provide a homogeneous way to asses this competence. This guide considers several levels of acquisition of the competence and provides the rubrics to be applied for each one. The guide has been subsequently validated with several pilot experiences. In this paper we will explain the problem-solving assessment guide for teachers and will show the pilot experiences that has been carried out. We will finally justify the validity of the method to assess the problem-solving competence.

Characterization of a glycosylase family gene specifically expressed during winter dormancy in woody plants

Winter dormancy is the strategy used by perennial plants to survive the harsh conditions of winter in temperate and cold regions. This complex mechanism is characterized by cessation of the meristems activity, which is accompanied by the budset, the acquisition of a high tolerance to the cold temperatures and, in the case of deciduous trees, by the senescence and leaf abscission. In long-lived forest species, the length of the dormancy period limits the growing season, affecting wood production and quality. A Suppression Subtractive Hybridization (SSH) enriched in genes overexpressed during the process of winter dormancy in chesnut stems identified a DNA glycosylase gene. In order to study its role in the establishment and maintenance of the winter dormancy, a molecular characterization and seasonal expression were performed. Furthermore, we have obtained poplar transgenic plantlets overexpressing the chesnut gene.

Application of NMR techniques for the evaluation of fruit internal quality and physical properties of food

Los alimentos son sistemas complejos, formados por diversas estructuras a diferentes escalas: macroscópica y microscópica. Muchas propiedades de los alimentos, que son importantes para su procesamiento, calidad y tratamiento postcosecha, están relacionados con su microestructura. La presente tesis doctoral propone una metodología completa para la determinación de la estructura de alimentos desde un punto de vista multi-escala, basándose en métodos de Resonancia Magnética Nuclear (NMR). Las técnicas de NMR son no invasivas y no destructivas y permiten el estudio tanto de macro- como de microestructura. Se han utilizado distintos procedimientos de NMR dependiendo del nivel que se desea estudiar. Para el nivel macroestructural, la Imagen de Resonancia Magnética (MRI) ha resultado ser muy útil para la caracterización de alimentos. Para el estudio microestructural, la MRI requiere altos tiempos de adquisición, lo que hace muy difícil la transferencia de esta técnica a aplicaciones en industria. Por tanto, la optimización de procedimientos de NMR basados en secuencias relaxometría 2D T1/T2 ha resultado ser una estrategia primordial en esta tesis. Estos protocolos de NMR se han implementado satisfactoriamente por primera vez en alto campo magnético. Se ha caracterizado la microestructura de productos alimentarios enteros por primera vez utilizando este tipo de protocolos. Como muestras, se han utilizado dos tipos de productos: modelos de alimentos y alimentos reales (manzanas). Además, como primer paso para su posterior implementación en la industria agroalimentaria, se ha mejorado una línea transportadora, especialmente diseñada para trabajar bajo condiciones de NMR en trabajos anteriores del grupo LPF-TAGRALIA. Se han estudiado y seleccionado las secuencias más rápidas y óptimas para la detección de dos tipos de desórdenes internos en manzanas: vitrescencia y roturas internas. La corrección de las imágenes en movimiento se realiza en tiempo real. Asimismo, se han utilizado protocolos de visión artificial para la clasificación automática de manzanas potencialmente afectadas por vitrescencia. El presente documento está dividido en diferentes capítulos: el Capítulo 2 explica los antecedentes de la presente tesis y el marco del proyecto en el que se ha desarrollado. El Capítulo 3 recoge el estado del arte. El Capítulo 4 establece los objetivos de esta tesis doctoral. Los resultados se dividen en cinco sub-secciones (dentro del Capítulo 5) que corresponden con los trabajos publicados bien en revistas revisadas por pares, bien en congresos internacionales o bien como capítulos de libros revisados por pares. La Sección 5.1. es un estudio del desarrollo de la vitrescencia en manzanas mediante MRI y lo relaciona con la posición de la fruta dentro de la copa del árbol. La Sección 5.2 presenta un trabajo sobre macro- y microestructura en modelos de alimentos. La Sección 5.3 es un artículo en revisión en una revista revisada por pares, en el que se hace un estudio microestrcutural no destructivo mediante relaxometría 2D T1/T2. la Sección 5.4, hace una comparación entre manzanas afectadas por vitrescencia mediante dos técnicas: tomografía de rayos X e MRI, en manzana. Por último, en la Sección 5.5 se muestra un trabajo en el que se hace un estudio de secuencias de MRI en línea para la evaluación de calidad interna en manzanas. Los siguientes capítulos ofrecen una discusión y conclusiones (Capítulo 6 y 7 respectivamente) de todos los capítulos de esta tesis doctoral. Finalmente, se han añadido tres apéndices: el primero con una introducción de los principios básicos de resonancia magnética nuclear (NMR) y en los otros dos, se presentan sendos estudios sobre el efecto de las fibras en la rehidratación de cereales de desayuno extrusionados, mediante diversas técnicas. Ambos trabajos se presentaron en un congreso internacional. Los resultados más relevantes de la presente tesis doctoral, se pueden dividir en tres grandes bloques: resultados sobre macroestructura, resultados sobre microestructura y resultados sobre MRI en línea. Resultados sobre macroestructura: - La imagen de resonancia magnética (MRI) se aplicó satisfactoriamente para la caracterización de macroestructura. En particular, la reconstrucción 3D de imágenes de resonancia magnética permitió identificar y caracterizar dos tipos distintos de vitrescencia en manzanas: central y radial, que se caracterizan por el porcentaje de daño y la conectividad (número de Euler). - La MRI proveía un mejor contraste para manzanas afectadas por vitrescencia que las imágenes de tomografía de rayos X (X-Ray CT), como se pudo verificar en muestras idénticas de manzana. Además, el tiempo de adquisición de la tomografía de rayos X fue alrededor de 12 veces mayor (25 minutos) que la adquisición de las imágenes de resonancia magnética (2 minutos 2 segundos). Resultados sobre microestructura: - Para el estudio de microestructura (nivel subcelular) se utilizaron con éxito secuencias de relaxometría 2D T1/T2. Estas secuencias se usaron por primera vez en alto campo y sobre piezas de alimento completo, convirtiéndose en una forma no destructiva de llevar a cabo estudios de microestructura. - El uso de MRI junto con relaxometría 2D T1/T2 permite realizar estudios multiescala en alimentos de forma no destructiva. Resultados sobre MRI en línea: - El uso de imagen de resonancia magnética en línea fue factible para la identificación de dos tipos de desórdenes internos en manzanas: vitrescencia y podredumbre interna. Las secuencias de imagen tipo FLASH resultaron adecuadas para la identificación en línea de vitrescencia en manzanas. Se realizó sin selección de corte, debido a que la vitrescencia puede desarrollarse en cualquier punto del volumen de la manzana. Se consiguió reducir el tiempo de adquisición, de modo que se llegaron a adquirir 1.3 frutos por segundos (758 ms por fruto). Las secuencias de imagen tipo UFLARE fueron adecuadas para la detección en línea de la podredumbre interna en manzanas. En este caso, se utilizó selección de corte, ya que se trata de un desorden que se suele localizar en la parte central del volumen de la manzana. Se consiguió reducir el tiempo de adquisicón hasta 0.67 frutos por segundo (1475 ms por fruto). En ambos casos (FLASH y UFLARE) fueron necesarios algoritmos para la corrección del movimiento de las imágenes en tiempo real. ABSTRACT Food is a complex system formed by several structures at different scales: macroscopic and microscopic. Many properties of foods that are relevant to process engineering or quality and postharvest treatments are related to their microstructure. This Ph.D Thesis proposes a complete methodology for food structure determination, in a multiscale way, based on the Nuclear Magnetic Resonance (NMR) phenomenon since NMR techniques are non-invasive and non-destructive, and allow both, macro- and micro-structure study. Different NMR procedures are used depending on the structure level under study. For the macrostructure level, Magnetic Resonance Imaging (MRI) revealed its usefulness for food characterization. For microstructure insight, MRI required high acquisition times, which is a hindrance for transference to industry applications. Therefore, optimization of NMR procedures based on T1/T2 relaxometry sequences was a key strategy in this Thesis. These NMR relaxometry protocols, are successfully implemented in high magnetic field. Microstructure of entire food products have been characterized for the first time using these protocols. Two different types of food products have been studied: food models and actual food (apples). Furthermore, as a first step for the food industry implementation, a grading line system, specially designed for working under NMR conditions in previous works of the LPF-TAGRALIA group, is improved. The study and selection of the most suitable rapid sequence to detect two different types of disorders in apples (watercore and internal breakdown) is performed and the real time image motion correction is applied. In addition, artificial vision protocols for the automatic classification of apples potentially affected by watercore are applied. This document is divided into seven different chapters: Chapter 2 explains the thesis background and the framework of the project in which it has been worked. Chapter 3 comprises the state of the art. Chapter 4 establishes de objectives of this Ph.D thesis. The results are divided into five different sections (in Chapter 5) that correspond to published peered reviewed works. Section 5.1 assesses the watercore development in apples with MRI and studies the effect of fruit location in the canopy. Section 5.2 is an MRI and 2D relaxometry study for macro- and microstructure assessment in food models. Section 5.3 is a non-destructive microstructural study using 2D T1/T2 relaxometry on watercore affected apples. Section 5.4 makes a comparison of X-ray CT and MRI on watercore disorder of different apple cultivars. Section 5.5, that is a study of online MRI sequences for the evaluation of apple internal quality. The subsequent chapters offer a general discussion and conclusions (Chapter 6 and Chapter 7 respectively) of all the works performed in the frame of this Ph.D thesis (two peer reviewed journals, one book chapter and one international congress).Finally, three appendices are included in which an introduction to NMR principles is offered and two published proceedings regarding the effect of fiber on the rehydration of extruded breakfast cereal are displayed. The most relevant results can be summarized into three sections: results on macrostructure, results on microstructure and results on on-line MRI. Results on macrostructure: - MRI was successfully used for macrostructure characterization. Indeed, 3D reconstruction of MRI in apples allows to identify two different types of watercore (radial and block), which are characterized by the percentage of damage and the connectivity (Euler number). - MRI provides better contrast for watercore than X-Ray CT as verified on identical samples. Furthermore, X-Ray CT images acquisition time was around 12 times higher (25 minutes) than MRI acquisition time (2 minutes 2 seconds). Results on microstructure: - 2D T1/T2 relaxometry were successfully applied for microstructure (subcellular level) characterization. 2D T1/T2 relaxometry sequences have been applied for the first time on high field for entire food pieces, being a non-destructive way to achieve microstructure study. - The use of MRI together with 2D T1/T2 relaxometry sequences allows a non-destructive multiscale study of food. Results on on-line MRI: - The use of on-line MRI was successful for the identification of two different internal disorders in apples: watercore and internal breakdown. FLASH imaging was a suitable technique for the on-line detection of watercore disorder in apples, with no slice selection, since watercore is a physiological disorder that may be developed anywhere in the apple volume. 1.3 fruits were imaged per second (768 ms per fruit). UFLARE imaging is a suitable sequence for the on-line detection of internal breakdown disorder in apples. Slice selection was used, as internal breakdown is usually located in the central slice of the apple volume. 0.67 fruits were imaged per second (1475 ms per fruit). In both cases (FLASH and UFLARE) motion correction was performed in real time, during the acquisition of the images.

Uncertainty Estimation for Performance Evaluation of a Confocal Microscope as Metrology Equipment

Both in industry and research, the quality control of micrometric manufactured parts is based on the measurement of parameters whose traceability is sometimes difficult to guarantee. In some of these parts, the confocal microscopy shows great aptitudes to characterize a measurand qualitatively and quantitatively. The confocal microscopy allows the acquisition of 2D and 3D images that are easily manipulated. Nowadays, this equipment is manufactured by many different brands, each of them claiming a resolution probably not in accord to their real performance. The Laser Center (Technical University of Madrid) has a confocal microscope to verify the dimensions of the micro mechanizing in their own research projects. The present study pretends to confirm that the magnitudes obtained are true and reliable. To achieve this, a methodology for confocal microscope calibration is proposed, as well as an experimental phase for dimensionally valuing the equipment by 4 different standard positions, with its seven magnifications and the six objective lenses that the equipment currently has, in the x–y and z axis. From the results the uncertainty will be estimated along with an effect analysis of the different magnifications in each of the objective lenses.

Three-dimensional mapping of real environments for cognitive robots navigation

Abstract The development of cognitive robots needs a strong “sensorial” support which should allow it to perceive the real world for interacting with it properly. Therefore the development of efficient visual-processing software to be equipped in effective artificial agents is a must. In this project we study and develop a visual-processing software that will work as the “eyes” of a cognitive robot. This software performs a three-dimensional mapping of the robot’s environment, providing it with the essential information required to make proper decisions during its navigation. Due to the complexity of this objective we have adopted the Scrum methodology in order to achieve an agile development process, which has allowed us to correct and improve in a fast way the successive versions of the product. The present project is structured in Sprints, which cover the different stages of the software development based on the requirements imposed by the robot and its real necessities. We have initially explored different commercial devices oriented to the acquisition of the required visual information, adopting the Kinect Sensor camera (Microsoft) as the most suitable option. Later on, we have studied the available software to manage the obtained visual information as well as its integration with the robot’s software, choosing the high-level platform Matlab as the common nexus to join the management of the camera, the management of the robot and the implementation of the behavioral algorithms. During the last stages the software has been developed to include the fundamental functionalities required to process the real environment, such as depth representation, segmentation, and clustering. Finally the software has been optimized to exhibit real-time processing and a suitable performance to fulfill the robot’s requirements during its operation in real situations.

Personalisation of intelligent homecare services adapted to children with motor impairments

Ambient Intelligence could support innovative application domains like motor impairments' detection at the home environment. This research aims to prevent neurodevelopmental disorders through the natural interaction of the children with embedded intelligence daily life objects, like home furniture and toys. Designed system uses an interoperable platform to provide two intelligent interrelated home healthcare services: monitoring of children¿s abilities and completion of early stimulation activities. A set of sensors, which are embedded within the rooms, toys and furniture, allows private data gathering about the child's interaction with the environment. This information feeds a reasoning subsystem, which encloses an ontology of neurodevelopment items, and adapts the service to the age and acquisition of expected abilities. Next, the platform proposes customized stimulation services by taking advantage of the existing facilities at the child's environment. The result integrates Embedded Sensor Systems for Health at Mälardalen University with UPM Smart Home, for adapted services delivery.

The development of a wind tunnel DAQ system by using Labview tools

This paper presents the experimental three-year learning activity developed by a group of teachers in a wind tunnel facility. The authors, leading a team of students, carried out a project consisting of the design, assembly and testing of a wind tunnel. The project included all stages of the process from its initial specifications to its final quality flow assessments, going through the calculation of each element, and the building of the whole wind tunnel. The group of (final year) students was responsible for the whole wind tunnel project as a part of their bachelor degree project. The paper focuses on the development of wind tunnel data acquisition software. This automatic tool is essential to improve the automation of the data acquisition of the wind tunnel facility systems, in particular for a 6DOF multi-axis force/torque sensor. This work can be considered as a typical example of real engineering practice: a set of specifications that has to be modified due to the constraints imposed throughout the project, in order to obtain the final result

El campo y la ciudad, áreas de reencuentro = The field and the city, areas of reunion

English Summary: Both in the remote origin of the city and the more recent one of urbanism as a remedial discipline conceived as a means of tackling with the urban and territorial impacts of industrialisation, the relatively balanced relation between town and country was a constant which endured until the progressive fragmentation and separation among the different areas of knowledge and action contributed to create a gap between them both, with disastrous consequences in environmental, social and economical terms. The tasks at hands from the perspective of integral sustainability is to promote a reunion throughout a new culture of territory. Resumen Tanto en los orígenes remotos de la ciudad como en los recientes del urbanismo como disciplina surgida para mitigar el impacto urbano y territorial del industrialismo, la relación relativamente equilibrada entre campo y ciudad fue una constante que se mantuvo hasta que la progresiva fragmentación entre áreas de conocimiento y de intervención contribuyó a un paulatino desencuentro entre ambos, de desastrosas consecuencias en términos sociales, ambientales y económicos. La tarea que se presenta desde la óptica de la sostenibilidad integral es propiciar el reencuentro a través de una nueva cultura del territorio

Paisaje de energías: conocimiento estético en el enfoque ambiental del proyecto

Desde hace ya varias décadas la praxis de la ecología ha venido reconociendo la necesidad de estudiar los múltiples sistemas de interacción del ser humano, como especie viva, y su entorno. Entidades espaciales como el paisaje geográfico son empleadas para delimitar sistemas territoriales operados por la sociedad, precisando campos concretos de su acción física, biológica y cultural. La ecología aborda así el conocimiento científico del territorio como asentamiento humano, rastrea sus patrones espaciales y analiza su compleja estructura funcional. En ese contexto, la transferencia de herramientas e instrumentos desde la ecología al ámbito proyectivo posee ya un bagaje de más de cinco décadas. Cada vez con más frecuencia el proyecto emplea parámetros, inventarios, fórmulas, indicadores y tecnologías que tratan de dar una respuesta ambientalmente adecuada a los condicionantes de contorno, por ejemplo aprovechando las condiciones climáticas en la optimización energética o proponiendo programas de usos del suelo que eviten perturbaciones en ecosistemas de interés. Con todo, en el momento presente surgen voces que, ante el dominio indiscutible de los enfoques netamente deterministas, tratan de recordar que los principios del pensamiento ecológico van más allá del mero control cuantitativo de los procesos biofísicos. Recuerdan que la etología demostró a principios del XX que el ser humano, como ser consciente, inviste una relación de intimidad con su entorno que supera tales perspectivas: a través de la correspondencia entre percepción y significación, entre lo físico y lo psíquico, entre interioridad y exterioridad, las personas abrazan la plenitud de aquello que les rodea en un acto de profunda conciliación afectiva. De tal ligadura de intimidad depende, sí o sí, y en toda su profundidad, la aceptación humana del entorno construido. A través de la noción de ambiente [Umwelt] se demuestra que la relación del hombre con su entorno es inseparable, bidireccional y coordinada y, por lo tanto, desde una posición coherente, la experiencia del espacio puede ser examinada a partir de la reciprocidad que constituyen, en continuidad, la persona y el lugar. De esta forma, la tesis dirige su objetivo principal a explorar y considerar, desde el proyecto, el significado y la influencia de la experiencia ambiental del espacio construido en la vida humana. Es más que probable que buena parte de los problemas de desafección del hombre con los paisajes transformados de su contemporaneidad tenga que ver con que tanto las intensidades de la experiencia y percepción humana, como la potestad interpretativa de sus productos culturales, incluyendo la arquitectura, han sido fuertemente reducidas. Ante este problema, la investigación toma como hipótesis la oportunidad que ofrece el pensamiento ecológico de reformular la experiencia estética como un acto de conocimiento, como un evento donde se da el encuentro físico y se construyen significados, donde se sancionan valores sociales y se mira hacia el futuro. Se ha de señalar que la presente tesis doctoral arranca en el Laboratorio de Paisaje del Grupo de Investigación Paisaje Cultural de la Universidad Politécnica de Madrid dirigido por Concha Lapayese y Darío Gazapo, y por tanto hace suyos para el estado del arte los principales conceptos e ideas bajo los que el trabajo teórico y práctico del grupo se viene orientando desde hace años: la consideración del paisaje como acontecimiento; la oscilación de la interpretación entre un paisaje específico y un paisaje genérico en un mundo globalizado; el reconocimiento de la experiencia estética del paisaje como una toma de conciencia social; y en definitiva, la reivindicación de la interioridad en el proyecto contemporáneo. La investigación profundiza en una línea de oportunidad que se abre al promover lo que se ha llamado un conocimiento por lo sentido como estrategia ambiental que permite contrarrestar mitos profundamente arraigados en las estructuras sociales. El primer paso en ese recorrido sería explorar ecológicamente el aporte de la experiencia estética; esto es, su consideración como forma de conocimiento específico. Resultaría pertinente impulsar la idea de la inmersión en el paisaje como fenómeno experiencial, sensual y corporal, y enfrentar, desde ahí, el problema de la aceptación social de lo nuevo y lo trasformado de acuerdo con el momento actual. La exploración sobre la afectividad en el ambiente no es, en cualquier caso, un asunto nuevo. Sin pretensiones de historiografía, dos momentos del siglo XX concentran el interés de la investigación. La primera se corresponde fundamentalmente con la segunda década del siglo, en relación a una serie de influencias que desde los avances científicos determinaron singulares aventuras del arte más experimental. La segunda se posiciona en el entorno de 1970, época en la que es conocido el interés que despertaron las cuestiones ambientales. En ambos casos se han estudiado aportaciones que desvelan conceptos determinantes en la definición de la experiencia estética como un evento de adquisición de conocimiento por lo sentido. Es conveniente adelantar el rol de centralidad que para la investigación tiene el concepto de energía, tal como el propio título subraya. La energía como realidad material y sensible es el sustrato que permite navegar por el principio de unidad epistemológica que subyace al pensamiento ecológico. Sus continuas referencias simbólicas, físicas y metafóricas entre los artistas estudiados no son un mero recurso iconográfico: mantienen inherente el principio de continuidad ambiental en el cual el ser humano y la inmensidad del cosmos navegan indisociables. Un discurso unificado y consistente sobre los aportes de la experiencia estética enfocada como forma de conocimiento por lo sentido hila la lectura histórica, conceptual y práctica de toda la investigación. Con ello se alcanza a hilvanar un diagrama conceptual, modelo de análisis proyectivo, que recoge ideas científicas, filosóficas y proyectivas. De alguna manera, el diagrama trata de dibujar, desde los principios del pensamiento ecológico, la correlación de continuidad que, vacilante, tensa, sutil y frágil se desplaza incesante e irresuelta entre interioridad y exterioridad. ABSTRACT Over the last few decades ecological practice has come to acknowledge a need for studying the multiple systems of interaction between the human being - inasmuch as it is a living species - and its environment. Spatial entities such as the geographic notion of landscape have been used to delimitate the territorial systems operated by society and to describe in detail specific fields of its physical, biological and cultural action. Ecology has thus managed to address the scientific knowledge of the territory as a human settlement, tracking its spatial patterns and analysing its complex functional structure. In this context, the transfer of tools and instruments from the field of ecology to that of design has a tradition already going back more than fifty years. Increasingly more often, design makes use of parameters, inventories, formulas, indicators and technologies to give an environmentally sound response to contour conditions: for instance, taking advantage of the local climate for the optimisation of energy consumption or proposing land uses that avoid disturbing valuable ecosystems. Yet in the present day some voices have arisen that, against the uncontested domination of purely positivistic approaches, are trying to draw attention to the fact that the principles of ecological thought go beyond mere quantitative control of biophysical processes. They point out that, in the early 20th century, ethology proved that the human being, as a conscious entity, invests itself into a relationship of intimacy with its environment that surpasses such perspectives: through the correspondences between perception and signification, between physical and psychological or between inside and outside, people embrace the entirety of their surroundings in an action of deep affective conciliation. It is on this link of intimacy that - fully and unquestionably - human acceptance of the built environment depends. Through the notion of environment [Umwelt] it can be proven that the relationship between the human being and its environment is inseparable, bidirectional and coordinated; and that, therefore, from a coherent position the experience of space can be examined through the reciprocity constituted continuously by person and place. Thus, the main goal in this thesis is to explore and acknowledge, from the standpoint of design, the meaning and influence of the environmental experience in human life. It is extremely likely that many of the issues with mankind’s alienation from the transformed landscapes of the present day arise from the fact that both the intensity of human perception and experience and the interpretive capacity of its cultural products –including architecture - have been greatly reduced. Facing this issue, research has taken as hypothesis the opportunity offered by ecological thought of reformulating aesthetic experience as an act of knowledge – as an event where physical encounter takes place and meanings are constructed; where social values are sanctioned and the path towards the future is drawn. This notwithstanding, the present thesis began in the Landscape Laboratory of the Technical University of Madrid Cultural Landscape Research Group (GIPC-UPM), led by Concha Lapayese and Darío Gazapo; and has therefore appropriated for its state of the art the main concepts and ideas that have been orienting the practical and theoretical work of the latter: the understanding of landscape as an event, the oscillation of interpretation between a specific and a generic landscape within a globalised world; the acknowledgement of the aesthetic experience of landscape as a way of acquiring social awareness; and, all in all, a vindication of interiority in contemporary design. An exploration has been made of the line of opportunity that is opened when promoting what has been termed knowledge through the senses as an environmental strategy allowing to counter myths deeply rooted in social structures. The first step in this path would be an ecological exploration of the contribution of the aesthetic experience; that is, its consideration as a type of specific knowledge. It would be pertinent to further the idea of immersion into the landscape as an experiential, sensual and corporeal phenomenon and, from that point, to face the issue of social acceptance of what is new and transformed according to the values of the present day. The exploration of affectivity in the environment is not, at any rate, a new topic. Without aspiring to make a history of it, we can mark two points in the 20th century that have concentrated the interest of this research. The first coincides with the second decade of the century and relates to a number of influences that, arising from scientific progress, determined the singular adventures of the more experimental tendencies in art. The second is centred around 1970: a period in which the interest drawn by environmental matters is well known. In both cases, contributions have been studied that reveal crucial concepts in defining the aesthetic experience as an event for the acquisition of knowledge through the senses. It is necessary to highlight the role of centrality that the concept of energy has throughout this research, as is evident even in its title. Energy as a material, sensitive reality is the substrate making it possible to navigate through the principle of epistemological unity underlying ecological thought. The continuous symbolic, physical and metaphorical references to it among the artists studied here are not a mere iconographic source: they remind of the inherency of the principle of environmental continuity within which the human being and the immensity of cosmos travel indissociably. A unified, consistent discourse on the contributions of the aesthetic experience addressed as knowledge through the senses weaves together the historic, conceptual and practical reading of the whole research. With it, a conceptual diagram is constructed – a model of design analysis – gathering together scientific, philosophical and design ideas. Somehow, the diagram tries to draw from the principles of ecological thought the correlation of continuity that, vacillating, tense, subtle and fragile, shifts incessantly and unresolved between interiority and exteriority.
