Elementos peatonales de las ciudades medias españolas : tipos, orígenes, relaciones y articulaciones

A través de esta tesis se busca aportar un análisis de los elementos peatonales que cubren las necesidades y las infraestructuras de apoyo al peatón, siendo un campo poco desarrollado en nuestro país a diferencia de otros como Dinamarca, Reino Unido, Alemania y Holanda, donde las actuaciones peatonales ejecutadas son tradicionales y muy exitosas. Se trata por tanto de un tema poco estudiado pero que adquiere singular importancia en estos años de búsqueda de nuevos modelos urbanos que eviten el derroche de recursos, y avancen hacia formas de movilidad más adecuadas a un mundo limitado y vulnerable. La investigación tiene un carácter eminentemente descriptivo cuyo principal valor es documentar y analizar sistemáticamente una realidad poco conocida, aportándose datos para entender el origen y desarrollo de las actuaciones peatonales. El propósito es ayudar a cimentar este campo en nuestro país, definiendo con precisión el estado de la cuestión geográficamente y dejando para un futuro una cartografía temática completa. El objeto general es estudiar y comprender los elementos peatonales de un número limitado de ciudades medias españolas, marcándose como objetivos específicos los siguientes: - Identificar y describir los principales elementos que conforman la red peatonal de las ciudades. ‐ Estudiar las tipologías espaciales dominantes, sus características y orígenes, pudiendo distinguir de un lado, las desarrolladas en la ciudad consolidada, como las actuaciones en los cascos antiguos; y por otro, las ejecutadas en la ciudad nueva a través de fórmulas arquitectónicas generalmente residenciales con espacios peatonales adjuntos. ‐ Analizar los referidos elementos para comprobar si han conformado redes de uso peatonal, si se han constituido articulando la ciudad como en el caso de los ejes lineales en las ciudades con río o mar, o si han influenciado el carácter del entorno en el que se han realizado, centrando el interés en los cascos históricos peatonalizados. ‐ Comprobar si hay actuaciones complementarias a los procesos de urbanización y mejora urbanística, así como la aprobación de ayudas y subvenciones para afrontar las mismas. ‐ Finalmente, describir y evaluar los procesos y procedimientos mediante los que se produce la peatonalización de determinadas áreas urbanas, los orígenes, los instrumentos y fechas de su puesta en marcha, aportando una cronología peatonal. La metodología comienza con la acotación de 22 ciudades españolas, capitales de provincia con una población entre 100.000 y 500.000 habitantes según los datos del INE del año 2009. La distribución es equilibrada con la selección de ciudades de costa, de interior, con río/ría, con carácter patrimonial, ciudades en islas, etc. El análisis de los elementos peatonales de estas urbes se realiza gracias a la gran resolución de las bases cartográficas públicas y privadas que hay en la actualidad en internet, especialmente con el uso de las herramientas de Google Earth y Google Maps en su versión “street view”, softwares que permiten un paseo virtual de cada ciudad detallándose con gran precisión las actuaciones peatonales. Las ciudades elegidas son: ‐ 11 ciudades costeras: Alicante, Almería, Bilbao, Cádiz, Castellón de la Plana, Huelva, Las Palmas de Gran Canaria, Palma de Mallorca, Santander, San Sebastián y Tarragona. ‐ 11 ciudades de interior: Albacete, Burgos, Córdoba, León, Lérida, Logroño, Oviedo, Murcia, Pamplona, Valladolid y Vitoria. Finalmente, por tener los porcentajes mas elevados de las áreas peatonales de sus casco histórico, se eligen 3 casos de ciudades representativas para un desarrollo peatonal en profundidad, seleccionándose Burgos, San Sebastián y Pamplona. Otros aspectos metodológicos interesantes a destacar, es la extensa documentación adquirida a través de las fuentes de Internet, sobre todo a la hora de desarrollar el último capítulo “Procesos de peatonalización de las ciudades españolas” centrado en las 3 ciudades elegidas. Se consulta las hemerotecas de periódicos locales, los boletines oficiales, las actas de los plenos de los Ayuntamientos y los documentos de planificación (Planes Generales, Planes Especiales, Planes y Proyectos Municipales, Planes de Movilidad), adquiriéndose una precisa información en cuanto a la cronología de las fechas y extensión del trabajo. Se complementa la metodología con las entrevistas a actores claves en el proceso peatonal, como el personal técnico de los Ayuntamiento y los técnicos redactores de los proyectos; y con la colaboración directa de los técnicos de los consistorios de las 3 ciudades seleccionadas, aportando todo tipo de información demandada. En la tesis, se introduce los elementos peatonales mediante el estudio de los espacios peatonales y los procesos de peatonalización existentes, a través del análisis de la literatura consultada aportándose información valiosa en cuanto a la definición de los modelos peatonales, exponiéndose una breve historia de las peatonalizaciones. Destacan las publicaciones de los expertos europeos en la materia como los autores Carmen Hass-Klau, Rolf Monheim, Rob Krier y Collin Buchanan. En España, las actuaciones peatonales fueron tardías en el tiempo en comparación con el resto de Europa, con casi 40 años de retraso. Las referencias bibliográficas españolas en esta materia son escasas siendo las mas significativas las realizadas por Alfonso Sanz y por el profesor Julio Pozueta destacando una de sus últimas publicaciones “La ciudad paseable” describiéndose los elementos peatonales existentes en las ciudades, sirviendo como modelo y ejemplo para esta investigación. En base a lo anterior, se definen los elementos peatonales como aquellos espacios públicos libres de edificación que, por sus características y diseño, garantizan un confortable uso estancial, de tránsito peatonal y están expresamente reservados para ello. En la tesis se detectan y se especifican los siguientes elementos peatonales: las calles y plazas peatonales, las aceras y bulevares de una anchura superior a 8 metros, los paseos peatonales, los elementos de paso (tradicionales y mecánicos), espacios peatonales ligados a nuevas áreas residenciales, los soportales y pasajes peatonales con una anchura mínima de 4 metros, recintos feriales, espacios libres y zonas verdes y parques. Para cada una de las 22 ciudades seleccionadas se realiza un exhaustivo inventario de los anteriores elementos a través de fichas, aportando un gran número de proyectos individuales ejecutados en cada urbe. Esta información se recoge gráficamente en 2 fotoplanos, conformándose como herramientas fundamentales para esta investigación. El Fotoplano 1 se hace sobre la base de la ciudad del Google Earth diferenciándose las áreas peatonales y las zonas verdes. En el Fotoplano 2, y con el soporte anterior, se distinguen las tipologías persistentes y dominantes como son los grandes ejes peatonales, las redes peatonales locales y los elementos peatonales singulares. Finalmente, a partir de los 2 fotoplanos, se realiza la denominada “Huella peatonal” que destaca por su atractivo y pregnancia, algo de lo que el campo de lo peatonal es muy útil. A través de la huella se obtiene una rápida información al tener el plano dos colores, color naranja para lo peatonal (formado por las áreas peatonales y zonas verdes) y color negro para el resto el resto no peatonal. Toda esta documentación gráfica y descriptiva de los elementos peatonales de cada ciudad, queda ampliamente recogida en el Anexo de la tesis. La “Huella peatonal” se considera como el plano básico en la investigación obteniendo una percepción rápida, clara y visual del espacio peatonal de cada ciudad. Se arroja información morfológica con respecto a la distribución espacial, articulación, equilibrio, modulación, cohesión, concentración peatonal, etc. de cada una de las ciudades seleccionadas. A través de la huella se resuelve muchos de las cuestiones enmarcadas como objetivos de la tesis, comprobándose de forma general, que los elementos peatonales dentro de la trama urbana están desarticulados ya que no hay una estructura que module la ciudad como un conjunto cohesionado. Se localizan pequeñas redes conectadas entre sí, que de forma heterogénea, están dispersas por la ciudad. Se verifica que los elementos peatonales con mayor concentración y presencia en las ciudades analizadas son los ejes peatonales, los cascos históricos y los elementos peatonales en las nuevas áreas residenciales. En la investigación, además de estos 3 elementos mencionados, se analiza con mayor profundidad otros tipos que destacan por su persistencia y repetición en la “Huella peatonal” de cada una de las 22 ciudades, como son las plazas peatonales, los soportales y los elementos singulares peatonales: espacios tradicionales (recintos feriales, pasajes, puentes históricos), nuevos elementos peatonales (pasarelas peatonales, elementos mecánicos de paso), áreas peatonales entorno a edificios culturales y otros casos como los consistentes en la recuperación y transformación de edificaciones y construcciones urbanas de diferente uso y tipología, en nuevas áreas peatonales. Se aporta luz sobre su definición, localización, cronología, proporción, presencia y génesis, facilitando resultados de cada uno de ellos. De forma paralela, se obtiene información de índole cuantitativa a través de las mediciones de la huella, obteniéndose datos y porcentajes de extensión de la ciudad, de las zonas peatonales y de las zonas verdes, de los cascos históricos y de sus superficies peatonales, de los metros lineales de dichos cascos históricos y de sus calles peatonales. Se proporcionan ratios e índices que se consideran fundamentales para una mejor comprensión peatonal de cada urbe. Se establece una clasificación de las ciudades en cada uno de los ámbitos descritos, destacando las ciudades de Pamplona, San Sebastián y Burgos por arrojar las cifras peatonales más positivas encabezando la mayoría de las tablas clasificatorias. La peor ciudad valorada es Alicante, seguida según criterio, de Almería, Palma de Mallorca y Las Palmas de GC. En el capítulo final de la investigación, se eligen las ciudades de Burgos, San Sebastián y Pamplona como casos de estudio representativos. El objetivo es obtener un conocimiento más preciso en cuanto a su origen, cronología y procesos de las peatonalizaciones. Cada ciudad se compone de un cuadro cronológicos por etapas, desarrollándose de forma exhaustiva cada una de ellas, enunciadas normalmente, como instrumentos de planeamiento o proyectos de urbanización, acompañadas de los planos de las actuaciones peatonales. Al final de cada etapa se aportan datos de las cifras de las peatonalizaciones que se van realizando, con un cuadro numérico de localizaciones, superficie peatonal, superficie reurbanizada, longitud peatonal y el grado de peatonalización del casco histórico, además de los datos acumulados por etapa. De las conclusiones cruzadas de estas 3 ciudades, destaca la comprobación de la tendencia de ir peatonalizando los centros antiguos llegando incluso al 100% de calles peatonales en el caso de San Sebastián. No obstante, es difícil confirmar si el objetivo es una peatonalización global de los cascos, ya que son muchas las variables que afectan e influyen en el proceso peatonal de cada ciudad. Se coteja adicionalmente cómo se extiende la cultura peatonal desde el interior al exterior, mas allá de los cascos históricos hacia los ensanches próximos. En cuanto al origen de las peatonalizaciones, se concluye que no hay una concepción inicial y teórica marcada, a partir de la cual se va desarrollando la trama peatonal de cada ciudad. Se puede afirmar que los procesos peatonales ejecutados son variados y de diversa índole, sin poder precisar un hecho como causa principal. Según el momento y las circunstancias, las peatonalizaciones responden a distintas iniciativas promovidas por los comerciantes, por las administraciones locales o por los técnicos de planeamiento, con sus expertas aportaciones en los planes. Estos tres agentes actúan como impulsores de proyectos individuales peatonales que se van solapando en el tiempo. Como punto final de la tesis, se propone una serie de nuevas líneas de investigación que pueden servir como estudio adicional y complementario, respondiendo a aspectos tan relevantes como cuestiones de índole económica, social y de movilidad, fuertemente ligadas a las peatonalizaciones, tal y como se demuestra en la literatura consultada. ABSTRACT This thesis aims to analyse the pedestrian elements dealing with the needs and infrastructures that support pedestrians, as this is a field that is little developed in our country, in comparison to other regions such as Denmark, the United Kingdom, Germany and the Netherlands, where the pedestrian actions implemented are traditional and highly successful. Therefore, even though little research has been done about this topic, this field is increasingly important throughout these years of search for urban models intended to prevent the waste of resources and to develop new mobility ways, more adapted to a limited, vulnerable world. This research is essentially descriptive and it mainly aims to document and systematically analysed a scarcely known reality by providing data in order to understand the origin and development of pedestrian actions. This thesis intends to lay the foundations of this field in Spain, accurately defining the state of the art from a geographical point of view and preparing a full thematic map that may be used in the future. The overall aim is to study and understand the pedestrian elements of a limited number of Spanish medium-size cities, establishing the following specific goals: - To identify and describe the main elements comprising cities' pedestrian networks. - To study of special predominant typologies, their features and origins, with the possibility to, on the one hand, make a difference between the typologies developed in well-established cities, such as the actions in historic quarters, and, on the other hand, those implemented in new cities through generally residential architectural formulae with adjoining pedestrian areas. - To analyse the said elements in order to check whether they have resulted in pedestrian-use networks, whether they have been established by organising the city, such as the linear axes in coastal and riverside cities, or whether they have had an impact on the character of the areas where these elements have been implemented, focusing on pedestrian historic quarters. - Check whether there are actions supplementary to the urban development and urban improvement processes, as well as the approval of financial support and subventions to deal with these actions. - Finally, to describe and assess the processes and procedures by which the pedestrianisation of certain urban areas is carried out, the origins, the instruments and the date of their implementation, providing a pedestrian timeline. The methodology starts by defining 22 Spanish cities, province capitals with a population ranging from 100,000 to 500,000 inhabitants, according to the data recorded by the Spanish Statistics Institute (INE) in 2009. The distribution of coastal, riverside and interior cities, as well as of patrimonial cities and cities in islands, etc. is well balanced. The analysis of the pedestrian elements of these cities is made with the great resolution of the public and private map databases that can be accessed on the Internet, especially using the "street-view" version of tools such as Google Earth and Google Maps, software applications that allow to go for a virtual walk in each city, providing highly precise details about the pedestrian actions. The following cities have been chosen: ‐ 11 coastal cities: Alicante, Almería, Bilbao, Cádiz, Castellón de la Plana, Huelva, Las Palmas de Gran Canaria, Palma de Mallorca, Santander, San Sebastián and Tarragona. ‐ 11 interior cities: Albacete, Burgos, Córdoba, León, Lérida, Logroño, Oviedo, Murcia, Pamplona, Valladolid and Vitoria. Finally, as they have the highest percentages regarding the pedestrian areas found in the historic quarters, 3 cities representing a deep pedestrian development have been chosen: Burgos, San Sebastián and Pamplona. Other significant methodological aspects are the many documents found from online sources, especially when preparing the last chapter: “Processes for the pedestrianisation of Spanish cities”, which focuses on the 3 cities chosen. Local newspaper and periodical libraries, official gazettes, the minutes of plenary sessions of councils and the zoning regulation documents (General Zoning Plans, Special Zoning Plans, Municipal Plans and Projects, Mobility Plans, etc.) have been consulted, obtaining accurate information regarding the timeline and the extension of the works carried out. The methodology is supplemented by interviews with key players in the pedestrianisation process, such as the technical staff in councils and the officers drafting and designing the projects, as well as with the direct collaboration by the officers of the councils of the 3 cities chosen, who provided all the information requested. The thesis introduces the pedestrian elements by studying pedestrian areas and existing pedestrianisation processes through the analysis of the literature consulted, providing valuable information for the definition of pedestrian models and showing a brief history and background of the pedestrianisation process. Remarkable papers published by some European experts in the field, such as Carmen Hass-Klau, Rolf Monheim and Collin Buchanan, are covered in the thesis. In Spain, the pedestrianisation actions were late in time in comparison to the rest of Europe, with at least 40 years of delay. The Spanish literature references in this field are limited. The most significant papers are those published by Alfonso Sanz and by Professor Julio Pozueta, with a special mention of one of his last works "La ciudad paseable" (The Walkable City), which describes the pedestrian elements found in the cities and is used a model and an example for this research. Based on the elements above, pedestrian elements are defined as those construction-free public areas that, due to their features and design, ensure the comfortable, convenient use of the spaces, characterised by pedestrian traffic and specifically reserved for this purpose. The thesis detects and specifies the following pedestrian elements: pedestrian streets and squares, pavements (sidewalks) and boulevards with a width exceeding 8 metres, pedestrian promenades, crossing elements (traditional and mechanical), pedestrian spaces linked to new residential areas, colonnades and pedestrian passages or narrow streets with a minimum width of 4 metres, exhibition sites, free spaces and green areas and parks. For each of the 22 cities chosen, a thorough inventory of the elements mentioned above has been made by using worksheets, providing a significant number of individual projects developed in each city. This information is graphically collected and displayed on 2 photomaps, resulting in tools essential for this research. Photomap 1 is made based on the city displayed by Google Earth, making a difference between pedestrian areas and green areas. On Photomap 2, using the tool mentioned above, a difference can be made between persistent and predominant typologies, such as the big pedestrian axes, the local pedestrian networks and singular pedestrian elements. Finally, the 2 photomaps are used in order to establish the so-called "pedestrian footprint", which is highlighted by its attractiveness and appeal, concepts for which the pedestrian field is very useful. With the pedestrian footprint, quick information can be obtained, since the map shows two colours: orange for pedestrian elements (made up of pedestrian areas and green areas) and black for the other non-pedestrian elements. A significant part of these graphic, descriptive documents about each city's pedestrian elements can be found in the thesis appendix. The "Pedestrian Footprint" is regarded in the research as the basic map, obtaining a quick, clear and visual perception of each city's pedestrian space. This footprint provides morphological information regarding the space distribution, the organisation, the balance, the modulation, the cohesion, the pedestrian concentration, etc. in each of the cities chosen. The pedestrian footprint helps solve many of the questions established as the thesis goals, proving that, in general, the pedestrian elements are not organised in the urban plot, as there is no structure modulating the city as a properly linked set of elements. Small networks linked to each other and heterogeneously scattered all over the city are found. It has been verified that the pedestrian elements with the highest concentration and presence in the cities analysed are the pedestrian axes, the historic quarters and the pedestrian elements found in the new residential areas. Besides these 3 elements mentioned, the research analyses in depth other types that are remarkable due to their persistence and repetition in the "Pedestrian Footprint" of each of the 22 cities, such as the pedestrian squares, the colonnades and the singular pedestrian elements: traditional spaces (exhibition sites, passages, historic bridges), new pedestrian elements (pedestrian footbridges, mechanical crossing elements), pedestrian areas around cultural buildings and other cases such as those consisting of recovering and transforming building and urban constructions, intended for a wide range of purposes and of different types, into new pedestrian areas. This work puts light on the definition, location, timeline, proportion, presence and origin, providing results for each of these concepts. At the same time, quantitative information is obtained by measuring the footprint, getting data and percentages on the size of the city, the pedestrian areas and the green areas, the historic quarters and the pedestrian zones, the linear metres of such historic quarters and pedestrian streets. The footprint also provides ratios and rates that are considered as essential in order to better understand the pedestrian elements of each city. A classification of cities is established for each of the areas described, highlighting the cities of Pamplona, San Sebastián and Burgos, as they provide the most positive pedestrian figures and lead most of the classification tables or rankings. According to the criteria considered, the city with the worst values is Alicante, followed by Almería, Palma de Mallorca and Las Palmas de Gran Canaria. In the final chapter in the thesis, the cities of Burgos, San Sebastián and Pamplona are chosen as representative study cases. The aim is to gain more accurate knowledge regarding the pedestrianisation origin, timeline and processes. Each city comprises a chronological sequence made of stages, each of which is thoroughly developed and usually announced as zoning plans or urban development projects, accompanied by the plans of the pedestrian actions. At the end of each stage, data with the figures of the pedestrianisation projects are provided, including a numerical chart with locations, pedestrian area, redeveloped urban areas, pedestrian length and pedestrianisation degree in the historic quarter, as well as the data cumulated throughout each stage. In the crossed conclusions on the three cities, the trend of gradually pedestrianising the historic quarters (even reaching the 100% of the pedestrian streets as in San Sebastián) is verified. However, it is difficult to confirm whether the purpose is to reach an overall pedestrianisation of the historic quarters, since there are many variables that affect and influence each city's pedestrianisation process. In addition, the spread of the pedestrian culture from the internal areas to the external areas, beyond the historic quarters to the nearby expansion areas, is compared. Regarding the origin of pedestrianisations, the thesis comes to the conclusion that there is no initial or theoretical conception from which each city's pedestrian plot is developed. The pedestrian processes implemented are varied and diverse but no fact can be specified as the main cause. Based on the moment and circumstances, the pedestrianisation processes are due to different initiatives promoted by shopkeepers, by the local administrations or by the zoning officers, with their expert contributions to the plans. These three players promote and drive individual pedestrianisation projects that overlap in the course of time. Finally, new lines of research are put forwards, as they can be taken as an additional study and as a supplement to this research, dealing with aspects as significant as the economic, social and mobility factors, closely linked to the pedestrianisation processes, as proven in the literature consulted.

A numerical and experimental study on energy saving solutions for mobile hydraulic machinery

Energy saving in mobile hydraulic machinery, aimed to fuel consumption reduction, has been one of the principal interests of many researchers and OEMs in the last years. Many different solutions have been proposed and investigated in the literature in order to improve the fuel efficiency, from novel system architectures and strategies to control the system to hybrid solutions. This thesis deals with the energy analysis of a hydraulic system of a middle size excavator through mathematical tools. In order to conduct the analyses the multibody mathematical model of the hydraulic excavator under investigation will be developed and validated on the basis of experimental activities, both on test bench and on the field. The analyses will be carried out considering the typical working cycles of the excavators defined by the JCMAS standard. The simulations results will be analysed and discussed in detail in order to define different solutions for the energy saving in LS hydraulic systems. Among the proposed energy saving solutions, energy recovery systems seem to be very promising for fuel consumption reduction in mobile machinery. In this thesis a novel energy recovery system architecture will be proposed and described in detail. Its dimensioning procedure takes advantage of the dynamic programming algorithm and a prototype will be realized and tested on the excavator under investigation. Finally the energy saving proposed solutions will be compared referring to the standard machinery architecture and a novel hybrid excavator with an energy saving up to 11% will be presented.

Conceptual Information Compression and Efficient Pattern Search

This paper introduces an encoding of knowledge representation statements as regular languages and proposes a two-phase approach to processing of explicitly declared conceptual information. The idea is presented for the simple conceptual graphs where conceptual pattern search is implemented by the so called projection operation. Projection calculations are organised into off-line preprocessing and run-time computations. This enables fast run-time treatment of NP-complete problems, given that the intermediate results of the off-line phase are kept in suitable data structures. The experiments with randomly-generated, middle-size knowledge bases support the claim that the suggested approach radically improves the run-time conceptual pattern search.

Relaciones de poder y memoria de un linaje. La intervención de la Casa de Moscoso en la Compostela de los siglos XIV-XVI

La ciudad ofrecía en la Baja Edad Media claras oportunidades para aquellos nobles que supieran situarse en el complejo juego de la política urbana y sus diversas instancias de poder. Para ello siempre se hace necesario contar con los apoyos sociales y físicos adecuados. La dinámica de enfrentamientos entre el Arzobispo de Santiago y el concello compostelano presenta un ejemplo inmejorable para valorar en su justa medida la inserción de la nobleza territorial en las relaciones de poder. Para abordar este caso se analizará la participación en la vida pública –también las revueltas urbanas– de la Casa de Moscoso tanto a través de su larga trayectoria de enfrentamientos con la Iglesia como mediante el estudio de su patrimonio urbano, incluyendo aquellos elementos relacionados con la creación de una memoria específica del linaje dentro de la ciudad.

Art-Map: concept of moving curatorial project and its practical realization in Aveiro

In this dissertation, I present the results of a project which aim was to find out and try an effective model of independent curatorial project executable in small and medium cities in Portugal. The concept of Moving Curatorial Project ARTMAP is a result of theoretical research and reflection about municipal exhibition spaces and possibility of presentation of the contemporary art in these spaces. To test if this curatorial project is realizable and if there are conditions to continue it, a first trial was implemented in Aveiro. A curated international exhibition, entitled “A Poética do Visual" occupied two municipal and two private gallery spaces and brought together 111 artists from 25 different countries. The art event was carried out in collaboration with the Municipality of Aveiro and the University of Aveiro, and involved several private cultural spaces in the city. This first experience showed that there are all conditions for the presentation of contemporary art in small and medium size locations in Portugal, and for this project to be replicated in other regions of the country.

Dynamic set pieces for CAMBADA team

Robotics is an emergent branch of engineering that involves the conception, manufacture, and control of robots. It is a multidisciplinary field that combines electronics, design, computer science, artificial intelligence, mechanics and nanotechnology. Its evolution results in machines that are able to perform tasks with some level of complexity. Multi-agent systems is a researching topic within robotics, thus they allow the solving of higher complexity problems, through the execution of simple routines. Robotic soccer allows the study and development of robotics and multiagent systems, as the agents have to work together as a team, having in consideration most problems found in our quotidian, as for example adaptation to a highly dynamic environment as it is the one of a soccer game. CAMBADA is the robotic soccer team belonging to the group of research IRIS from IEETA, composed by teachers, researchers and students of the University of Aveiro, which annually has as main objective the participation in the RoboCup, in the Middle Size League. The purpose of this work is to improve the coordination in set pieces situations. This thesis introduces a new behavior and the adaptation of the already existing ones in the offensive situation, as well as the proposal of a new positioning method in defensive situations. The developed work was incorporated within the competition software of the robots. Which allows the presentation, in this dissertation, of the experimental results obtained, through simulation software as well as through the physical robots on the laboratory.

Goal detection using laser range finder for goalkeeper and striker from CAMBADA team

For a robot be autonomous and mobile, it requires being attached with a set of sensors that helps it to have a better perception of the surrounding world, to manage to localize itself and the surrounding objects. CAMBADA is the robotic soccer team of the IRIS research group, from IEETA, University of Aveiro, that competes in the Middle-Size League of RoboCup. In competition, in order to win, the main objective of the game it's to score more goals than the conceded, so not conceding goals, and score as much as possible it's desirable, thus, this thesis focus on adapt an agent with a better localization capacity in defensive and offensive moments. It was introduced a laser range finder to the CAMBADA robots, making them capable of detecting their own and the opponent goal, and to detect the opponents in specific game situations. With the new information and adapting the Goalie and Penalty behaviors, the CAMBADA goalkeeper is now able to detect and track its own goal and the CAMBADA striker has a better performance in a penalty situation. The developed work was incorporated within the competition software of the robots, which allows the presentation, in this thesis, of the experimental results obtained with physical robots on the laboratory field.

UTFORMNING AV GÅNG-, CYKEL- OCH MOPED-NÄT ANPASSAT FÖR ELCYKEL

Purpose: An increase in the number of pedelecs on Swedish roads is according to studies soon reality. This creates a need to adapt the bmp-grid (bike-, moped- and pedestrian-grid) to pedelecs for them to experience good security, accessibility and comfort while using it. The guidelines Swedish municipalities follow are VGU(Design of Roads and Streets) and the GCM-manual(Bike-, moped-, and pedestrian-manual) which currently do not take society’s future increase of pedelecs into account. VGU and the GCM-manual are tools that are commonly used during planning and design of roads and streets. The aim of the thesis is to use current advice and recommendations on how to adapt the bmp-grid to the pedelec and with this complete current guidelines for bmp-infrastructure. Method: The document-analysis is made on current federal documents that have an impact on bmp-design. Scetch-suggestions were then developed from the author’s personal improvement suggestions and from advice and recommendations gathered during the document-analysis and the theoretical framework. Findings: It was discovered that if the bmp-grid’s design allow bikes traveling up to 30km/h and has a good standard for bicycles according to VGU, then the infrastructure generally fulfil the needs of the pedelec. Altough there are still areas in VGU that needs complements. This need to be done on the design-guidelines so they can aid the adaption of the infrastructure to the pedelec during the planning- and design process. Necessary steps according to the result is to give clearer notifications on bmp-design, issue guidelines for choosing DTS, motivate minimal widths on roads, categories bikers and pedestrians into separate groups, give out more detailed descriptions of when separation of bikers and pedestrians should be done and also to specify different types of bike-users. When taking needs and claim of the pedelec into consideration the result shows that: adaption of the whole bmp-grid to the pedelec is not possible, to simplify priorities the bmp-grid needs to be divided into different sections, space should be taken from the car-traffic, solutions with mixed-traffic and bike-fields for pedelecs can be used in low-speed areas, larger opportunities to connect towns to increase commuting with bicycles appeared with the pedelec. Implications: After examining current guidelines regarding the design of the bmp-grid and gathering opinions on this from interviews the conclusion is that several areas in VGU needs completion. The following are recommendations on how to take the pedelec into consideration during the design-process:• Connect towns and urban-areas with bmp-grids to make use of pedelecs capacity.• Where there is not enough space for both cars and separated pedelec- and bike lanes the speed for car-traffic can be lowered to 30km/h. This creates opportunities with mixed-traffic or bike-lanes.• The width of existing roads and streets are often greater than what’s described in VGU. They can be made smaller to free space on roads for bicycle-infrastructure.• To prioritize which parts of the bmp-grid that needs design to allow pedelecs the bmp-grid can be divided into main- and local grid. The main grid should be design with consideration to the needs and claim of the pedelecs. Limitations: The limitation of the study lies in that none of the interviews where done with employees in any of the bigger municipalities in Sweden. This gives the study a general application in small- to middle-sized cities but not in bigger cities.Keywords: elcykel, ebike, pedelec, utformning, cykel, infrastruktur, infrastructure, society, planering, utformning, säkerhet, fordonstyp

RANKING DEL BIENESTAR SEGÚN CATEGORÍAS URBANAS EN LA ARGENTINA (2001)

Existe una estrecha relación entre bienestar y escala urbana. Considerando una combinación ponderada de indicadores socioeconómicos y ambientales tenemos que las Aglomeraciones de Tamaño Intermedio (ATIS) grandes (entre 400.000 y 999.999 habitantes) poseen el mayor nivel de bienestar, seguidas por las ATIS medias (entre 50.000 y 399.999). Las ciudades grandes (más de un millón de habitantes) recientemente se ubican en un tercer escalón. Cruzando la escala urbana y la región se evidencian mejor estas diferencias. La mejor conjunción corresponde a las ATIS medias patagónicas, mientras que la peor es la que reúne a las ATIS medias del Nordeste Argentino (NEA). Es decir que, más allá de la jerarquía urbana como factor de diferenciación, también deben considerarse los contextos regionales para intentar dimensionar más ajustadamente las diferencias del bienestar en Argentina. ABSTRACT A very close relationship exists between well-being and urban scale. If we consider a weighted combination of socioeconomic and environmental indicators, we find that bigger middle-sized cities (ATIS in Spanish) of between 400,000 and 1,000,000 inhabitants have the highest level of well-being, followed by middle ATIS, or cities, of 50,000 to 400,000 in population. The largest cities, those with a population of more than 1,000,000 ranked third. However, these differences are better evidenced by crossing urban scale and region. In other words, beyond urban hierarchy as a differentiation factor, the regional context must also be considered to more accurately gage differences in well-being.

Thermal performance optimization of building aspect ratio and south window size in five cities having different climatic characteristics of Turkey

The aim of the study is to establish optimum building aspect ratios and south window sizes of residential buildings from thermal performance point of view. The effects of 6 different building aspect ratios and eight different south window sizes for each building aspect ratio are analyzed for apartments located at intermediate floors of buildings, by the aid of the computer based thermal analysis program SUNCODE-PC in five cities of Turkey: Erzurum, Ankara, Diyarbakir, Izmir, and Antalya. The results are evaluated in terms of annual energy consumption and the optimum values are driven. Comparison of optimum values and the total energy consumption rates is made among the analyzed cities.

Middle aged wasps mate through most of the year, without regard to body size, ovarian development and nestmateship: a laboratory study of the primitively eusocial wasp Ropalidia marginata

We studied the mating behaviour of the primi-tively eusocial wasp Ropalidia marginata and the factors that may influence sperm transfer. By introducing a male and a female R. marginata into ventilated transparent plastic boxes, we were able to observe mating behaviour, and it involved mounting and short or long conjugation of the wasps. Dissection of female wasps after the observation indicated that long conjugation is a good behavioural predictor of sperm transfer. This finding makes it possible to obtain mated females without dissecting them every time. We tested the effect of age, season, relatedness, body size and female's ovarian status on mating. Under laboratory conditions, mating success declined rapidly below and above the ages 5-20 days. Within this age range mating success was significantly low in December compared to other months tested. There was no nestmate discrimination, and there was no influence of male and female body size or of the ovarian state of the female on the probability of sperm transfer.

Meta-analysis of the influence of experimental design on effect size in peer tutoring outcomes in elementary, middle and high school settings.

A meta-analysis was undertaken on a form of cooperative learning, peer tutoring. The effects of experimental design on outcomes were explored, as measured by Effect Size (ES). 185 studies were included in the meta-analysis. Highest ES were reported for quasi-experimental studies. ES reduced as experimental design moved from single pre-test factor matched, to multiple-factor matched randomized controlled trials. ES reduced when designs used standardised, rather than self-designed measures, The implications for future meta-analyses and research in cooperative learning are explored.

The influence of experimental design on the magnitude of the effect size -peer tutoring for elementary, middle and high school settings: A meta-analysis

A meta-analysis was undertaken on a form of cooperative learning, peer tutoring. The effects of experimental design on outcomes were explored, as measured by Effect Size (ES). Forty three articles with 82 effect size studies were included in the meta-analysis. Highest ES were reported for quasi-experimental studies. ES reduced as experimental design moved from single pre-test factor matched, to multiple-factor matched randomized controlled trials. ES reduced when designs used standardised, rather than self-designed measures. The implications for future meta-analyses and research in cooperative learning are explored.
