As an antidote to the substandard tenement apartment, the ideal of the "small house" (Kleinhaus) was ubiquitous in housing debates in Germany before World War One. Denoting a modestly sized two-story family house aligned with the street, it had its origins in the Middle Ages, during which it was constructed to serve the humble domestic needs of urban craftsmen who lived and worked in thriving trade cities including Lübeck, Bremen, Hamburg, Augsburg, Nuremberg, and Ulm. For modern promoters of low-density alternatives to the tenement, the Kleinhaus was an ideal model for mass appropriation. Unlike foreign and untranslatable dwelling models like the "villa" and the "cottage," the Kleinhaus conveyed something that was both urban and quintessentially Germanic. It was thus enlisted by housing reformers to strengthen local cultural identity whilst raising the standards of the nation's housing stock. This article examines the significance of the Kleinhaus in fostering dialogue between the fields of architecture and planning, and considers its embeddedness in a wider project of cultural nationalism in pre-war Germany.

Historic Arab cities show a variety of origins and modernization patterns; these were conditioned on the one hand by external factors such as pre-existing settlements, deliberate locational choices and prevailing dynastic modernization and transformation, on the other hand by internal factors such as the morphological principles implied in individual architecture components and in genesis of the urban environment In this paper, we will try to highlight the socio-cultural aspects in the city structure context and their relations to the city morphology referring to the underlying shaping forces of urban form which, drawing on related, deep-rooted human attitudes, constitute the real agents of physical manifestation and are source of the non-material qualities transpiring through materials expressions. This presentation seeks to understand the significance of the city structure in different dimensions of urban environment.Understanding the interaction between underlying political, economic, socio-cultural forces as deep structure elements is an important aspect of research objectives. This paper also studies how physical or functional changes follow changes in the underlying forces among the modernization process and city structure regeneration.The approach to the research objectives is based on two methodologies:• Deductive: a theoretical investigation based on the properties of the city structure, definitions, principles of design, and the dilemma of achieving modernization is as much cultural as technical. This combines information from literature reviews and the ideas of key figures in the urban development field and the place-identity, social identity and identity process as theories for cultural models of the city.• Inductive: a study of Algiers as example of historical settlements that have undergone much change processes. The study looks to elicit the images of the city main structure to support the theoretical propositions of surface and deep structural city elements. The conclusion to this part is based on an analysis of the case study.The research concludes its conclusion through the theoretical and empirical work the socio- cultural aspect in the modernization process as a board and complex field.Moreover, it introduces the concept of City Structure as a new way to envisage urban Conservation studies.

Esta tesis presenta contribuciones en el campo de la planificación automática y la programación de tareas, la rama de la inteligencia artificial que se ocupa de la realización de estrategias o secuencias de acciones típicamente para su ejecución por parte de vehículos no tripulados, robots autónomos y/o agentes inteligentes. Cuando se intenta alcanzar un objetivo determinado, la cooperación puede ser un aspecto clave. La complejidad de algunas tareas requiere la cooperación entre varios agentes. Mas aún, incluso si una tarea es lo suficientemente simple para ser llevada a cabo por un único agente, puede usarse la cooperación para reducir el coste total de la misma. Para realizar tareas complejas que requieren interacción física con el mundo real, los vehículos no tripulados pueden ser usados como agentes. En los últimos años se han creado y utilizado una gran diversidad de plataformas no tripuladas, principalmente vehículos que pueden ser dirigidos sin un humano a bordo, tanto en misiones civiles como militares. En esta tesis se aborda la aplicación de planificación simbólica de redes jerárquicas de tareas (HTN planning, por sus siglas en inglés) en la resolución de problemas de enrutamiento de vehículos (VRP, por sus siglas en inglés) [18], en dominios que implican múltiples vehículos no tripulados de capacidades heterogéneas que deben cooperar para alcanzar una serie de objetivos específicos. La planificación con redes jerárquicas de tareas describe dominios utilizando una descripción que descompone conjuntos de tareas en subconjuntos más pequeños de subtareas gradualmente, hasta obtener tareas del más bajo nivel que no pueden ser descompuestas y se consideran directamente ejecutables. Esta jerarquía es similar al modo en que los humanos razonan sobre los problemas, descomponiéndolos en subproblemas según el contexto, y por lo tanto suelen ser fáciles de comprender y diseñar. Los problemas de enrutamiento de vehículos son una generalización del problema del viajante (TSP, por sus siglas en inglés). La resolución del problema del viajante consiste en encontrar la ruta más corta posible que permite visitar una lista de ciudades, partiendo y acabando en la misma ciudad. Su generalización, el problema de enrutamiento de vehículos, consiste en encontrar el conjunto de rutas de longitud mínima que permite cubrir todas las ciudades con un determinado número de vehículos. Ambos problemas cuentan con una fuerte componente combinatoria para su resolución, especialmente en el caso del VRP, por lo que su presencia en dominios que van a ser tratados con un planificador HTN clásico supone un gran reto. Para la aplicación de un planificador HTN en la resolución de problemas de enrutamiento de vehículos desarrollamos dos métodos. En el primero de ellos presentamos un sistema de optimización de soluciones basado en puntuaciones, que nos permite una nueva forma de conexión entre un software especializado en la resolución del VRP con el planificador HTN. Llamamos a este modo de conexión el método desacoplado, puesto que resolvemos la componente combinatoria del problema de enrutamiento de vehículos mediante un solucionador específico que se comunica con el planificador HTN y le suministra la información necesaria para continuar con la descomposición de tareas. El segundo método consiste en mejorar el planificador HTN utilizado para que sea capaz de resolver el problema de enrutamiento de vehículos de la mejor forma posible sin tener que depender de módulos de software externos. Llamamos a este modo el método acoplado. Con este motivo hemos desarrollado un nuevo planificador HTN que utiliza un algoritmo de búsqueda distinto del que se utiliza normalmente en planificadores de este tipo. Esta tesis presenta nuevas contribuciones en el campo de la planificación con redes jerárquicas de tareas para la resolución de problemas de enrutamiento de vehículos. Se aplica una nueva forma de conexión entre dos planificadores independientes basada en un sistema de cálculo de puntuaciones que les permite colaborar en la optimización de soluciones, y se presenta un nuevo planificador HTN con un algoritmo de búsqueda distinto al comúnmente utilizado. Se muestra la aplicación de estos dos métodos en misiones civiles dentro del entorno de los Proyectos ARCAS y AEROARMS financiados por la Comisión Europea y se presentan extensos resultados de simulación para comprobar la validez de los dos métodos propuestos. ; This thesis presents contributions in the field of automated planning and scheduling, the branch of artificial intelligence that concerns the realization of strategies or action sequences typically for execution by unmanned vehicles, autonomous robots and/or intelligent agents. When trying to achieve certain goal, cooperation may be a key aspect. The complexity of some tasks requires the cooperation among several agents. Moreover, even if the task is simple enough to be carried out by a single agent, cooperation can be used to decrease the overall cost of the operation. To perform complex tasks that require physical interaction with the real world, unmanned vehicles can be used as agents. In the last years a great variety of unmanned platforms, mainly vehicles that can be driven without a human on board, have been developed and used both in civil and military missions. This thesis deals with the application of Hierarchical Task Network (HTN) planning in the resolution of vehicle routing problems (VRP) [18] in domains involving multiple heterogeneous unmanned vehicles that must cooperate to achieve specific goals. HTN planning describes problem domains using a description that decomposes set of tasks into subsets of smaller tasks and so on, obtaining low-level tasks that cannot be further decomposed and are supposed to be executable. The hierarchy resembles the way the humans reason about problems by decomposing them into sub-problems depending on the context and therefore tend to be easy to understand and design. Vehicle routing problems are a generalization of the travelling salesman problem (TSP). The TSP consists on finding the shortest path that connects all the cities from a list, starting and ending on the same city. The VRP consists on finding the set of minimal routes that cover all cities by using a specific number of vehicles. Both problems have a combinatorial nature, specially the VRP, that makes it very difficult to use a HTN planner in domains where these problems are present. Two approaches to use a HTN planner in domains involving the VRP have been tested. The first approach consists on a score-based optimization system that allows us to apply a new way of connecting a software specialized in the resolution of the VRP with the HTN planner. We call this the decoupled approach, as we tackle the combinatorial nature of the VRP by using a specialized solver that communicates with the HTN planner and provides all the required information to do the task decomposition. The second approach consists on improving and enhancing the HTN planner to be capable of solving the VRP without needing the use of an external software. We call this the coupled approach. For this reason, a new HTN planner that uses a different search algorithm from these commonly used in that type of planners has been developed and is presented in this work. This thesis presents new contributions in the field of hierarchical task network planning for the resolution of vehicle routing problem domains. A new way of connecting two independent planning systems based on a score calculation system that lets them cooperate in the optimization of the solutions is applied, and a new HTN planner that uses a different search algorithm from that usually used in other HTN planners is presented. These two methods are applied in civil missions in the framework of the ARCAS and AEROARMS Projects funded by the European Commission. Extensive simulation results are presented to test the validity of the two approaches.

"Traditional approaches to space tend to view public space mainly as a shell or container, focussing on its morphological structures and functional uses and ignoring its ever-changing meanings, contested or challenged uses, and the fact that is an outcome of contextual and on-going dynamics between social actors, their cultures, and power relations. The key role of space in determining the structures of opportunities for social action, the fluidity of its social meaning and the changing degree of "publicness" of a space remains a highly neglected field of academic inquiry and professional practice. As Lefebvre identified, there are segmented and segmenting approaches to analysis and conceptualisation of space among (and within) academic disciplines, but particularly in architecture, planning and the social sciences. Four decades later, these dilemmas are still relevant. The editors believe that there is need and potential to further develop pedagogical tools that enable a more systematic reading of the micro-scale of everyday life, with its rhythms and fluidity of meanings"--

Traditional approaches to understand space tend to view public space mainly as a shell or container, focussing on its morphological structures and functional uses. That way, its ever-changing meanings, contested or challenged uses have been largely ignored, as well as the contextual and on-going dynamics between social actors, their cultures, and struggles. The key role of space in enabling spatial opportunities for social action, the fluidity of its social meaning and the changing degree of ""publicness"" of a space remain unexplored fields of academic inquiry and professional practice.
