Housing plans and urban rehabilitation in Spain, 1992-2012

This paper explores the urban rehabilitation projects promoted by the Spanish Government between 1992 and 2012 through housing plans. The analysis is based on the comparison of programmes and estimations gathered in these plans with actual housing production within this period in order to find the connection between sectoral housing planning and real estate cycles in these last twenty years. During the period under review, six state housing plans, that were mainly focused on the promotion of newly-constructed state-subsidised housing, were developed, including the Areas of Integrated Rehabilitation programmes (ARI programmes). In spite of the relevance and growing complexity of these programmes, these played a subsidiary role in the government housing policy and were insignificant regarding the whole real estate production in this period.

Evaluation of school plans

A model is presented for simulation and economic evaluation of school plans within the framework of city master planning. The model has been applied to plans for a Swedish city, Västerȧs, and some illustrative results are reported.

Enhancing Evacuation Plans with a Situation Awareness System Based on End-User Knowledge Provision.

Recent disasters have shown that having clearly defined preventive procedures and decisions is a critical component that minimizes evacuation hazards and ensures a rapid and successful evolution of evacuation plans. In this context, we present our Situation-Aware System for enhancing Evacuation Plans (SASEP) system, which allows creating end-user business rules that technically support the specific events, conditions and actions related to evacuation plans. An experimental validation was carried out where 32 people faced a simulated emergency situation, 16 of them using SASEP and the other 16 using a legacy system based on static signs. From the results obtained, we compare both techniques and discuss in which situations SASEP offers a better evacuation route option, confirming that it is highly valuable when there is a threat in the evacuation route. In addition, a study about user satisfaction using both systems is presented showing in which cases the systems are assessed as satisfactory, relevant and not frustrating.

Loose Coupling Based Reference Scheme for Shop Floor-Control-System/Production-Equipment Integration.

Acoplamiento del sistema informático de control de piso de producción (SFS) con el conjunto de equipos de fabricación (SPE) es una tarea compleja. Tal acoplamiento involucra estándares abiertos y propietarios, tecnologías de información y comunicación, entre otras herramientas y técnicas. Debido a la turbulencia de mercados, ya sea soluciones personalizadas o soluciones basadas en estándares eventualmente requieren un esfuerzo considerable de adaptación. El concepto de acoplamiento débil ha sido identificado en la comunidad de diseño organizacional como soporte para la sobrevivencia de la organización. Su presencia reduce la resistencia de la organización a cambios en el ambiente. En este artículo los resultados obtenidos por la comunidad de diseño organizacional son identificados, traducidos y organizados para apoyar en la solución del problema de integración SFS-SPE. Un modelo clásico de acoplamiento débil, desarrollado por la comunidad de estudios de diseño organizacional, es resumido y trasladado al área de interés. Los aspectos claves son identificados para utilizarse como promotores del acoplamiento débil entre SFS-SPE, y presentados en forma de esquema de referencia. Así mismo, este esquema de referencia es presentado como base para el diseño e implementación de una solución genérica de acoplamiento o marco de trabajo (framework) de acoplamiento, a incluir como etapa de acoplamiento débil entre SFS y SPE. Un ejemplo de validación con varios conjuntos de equipos de fabricación, usando diferentes medios físicos de comunicación, comandos de controlador, lenguajes de programación de equipos y protocolos de comunicación es presentado, mostrando un nivel aceptable de autonomía del SFS. = Coupling shop floor software system (SFS) with the set of production equipment (SPE) becomes a complex task. It involves open and proprietary standards, information and communication technologies among other tools and techniques. Due to market turbulence, either custom solutions or standards based solutions eventually require a considerable effort of adaptation. Loose coupling concept has been identified in the organizational design community as a compensator for organization survival. Its presence reduces organization reaction to environment changes. In this paper the results obtained by the organizational de sign community are identified, translated and organized to support the SFS-SPE integration problem solution. A classical loose coupling model developed by organizational studies community is abstracted and translated to the area of interest. Key aspects are identified to be used as promoters of SFS-SPE loose coupling and presented in a form of a reference scheme. Furthermore, this reference scheme is proposed here as a basis for the design and implementation of a generic coupling solution or coupling framework, that is included as a loose coupling stage between SFS and SPE. A validation example with various sets of manufacturing equipment, using different physical communication media, controller commands, programming languages and wire protocols is presented, showing an acceptable level of autonomy gained by the SFS.

Understanding sprint velocity fluctuations for improved project plans with Scrum: a case study

Starting from the documentation of high sprint velocity fluctuations in a Scrum project, this paper presents a thorough approach to identify the sources of issues arising in the context of Scrum implementation. Given that Scrum provides guidance on identifying process issues but not their root causes, various approaches are explored. This is of great relevance because Scrum defines project schedules relying heavily on sprint velocity and because it is the most widely used agile methodology. The findings provide a new approach to evaluate such fluctuations and establish a more realistic project assessment than what is currently defined by Scrum. In this respect, this paper contributes to improve the understanding of the software development process using this agile framework.

Aproximación a la arquitectura popular en la Mancha Baja. El caso de Manzanares

La tesis se compone de una primera parte introductoria, en la que se recogen las distintas opiniones y definiciones de la arquitectura “popular”, el estado de la cuestión, comentando los artículos y publicaciones realizados sobre la Mancha. La segunda parte profundiza en aspectos generales previos al análisis edificatorio central de la tesis, con los siguientes capítulos: -Estudio de los condicionantes físicos, históricos, socio-económicos y culturales de la comarca de la Mancha Baja. Acotando el territorio. -Una visión general sobre la arquitectura tradicional de la provincia de Ciudad Real, por comarcas. -Un estudio de las distintas tipologías edificatorias tradicionales, con ejemplos en la comarca manchega. -El análisis de materiales constructivos, elementos y sistemas utilizados en las construcciones tradicionales en la Mancha Baja. La tercera parte, desde la premisa de la representación gráfica, apoyado en un anexo con dibujos de ciento treinta y siete edificios populares de Manzanares y comarca, estudia: El trazado urbano y las casas de Manzanares; desde los levantamientos de plantas, alzados y secciones, emplazamiento en la manzana y fotografías, se realiza una descripción completa, con noventa y seis ejemplos. Además de llegar a las conclusiones derivadas del análisis de estas edificaciones, los objetivos pretendidos con este estudio serían también: Realizar un primer trabajo aproximativo, desde la visión arquitectónica, de la arquitectura tradicional manchega. Recopilar toda la información existente que pueda relacionarse con la arquitectura popular en la comarca, y citar los escritos y publicaciones de referencia para posteriores estudios. Se estudia la geomorfología, el clima, el territorio, la economía, la sociología, etc…, para obtener una información clave, además de los materiales, técnicas constructivas y morfología de las edificaciones. Se destaca el apartado de los edificios preindustriales tradicionales, como molinos de viento, de agua, palomares, pósitos y bodegas con el análisis de varios ejemplos, por su importante presencia en las poblaciones. Por último se desarrolla un amplio bloque sobre bibliografía de arquitectura popular, la consultada y la general. La arquitectura popular de la mancha baja es tapial cubierto de teja árabe, cerrada al exterior, pero abierta a grandes patios, de planta baja y cámaras altas, con elementos auxiliares de protección y acceso, que revisten la aparente simplicidad volumétrica de estos complejos, viviendas-almacén. Con un complejo programa tanto agrícola como doméstico. De gran protección frente al clima, con escasa decoración, esquemas espaciales primitivos y con mayor envergadura estructural en las dependencias agropecuarias. Una arquitectura que mezcla el uso doméstico y el productivo, pero que al evolucionar aumenta su diferenciación. Edificios que mantienen las mismas cualidades estéticas, repitiendo formas y volúmenes, pero de peculiares configuraciones espaciales, se repiten los materiales y técnicas constructivas, así como elementos arquitectónicos con pocas variaciones, pero no existen dos conjuntos similares. No podemos utilizar un ejemplo como modelo de casa manchega. Evoluciona de la casa bloque, básica y primitiva, con ejemplos escasos en las poblaciones más deprimidas, a la casa compleja, donde se separan con claridad las dependencias agropecuarias de las vivideras. Evoluciona de una casa rural, con los mismos esquemas, ya se ubique en el campo o en núcleos de población, a la casa urbana, entre medianerías, en la que se puede encontrar una transformación paralela, desarrollándose programas domésticos, más especializados, mezclados con arquitecturas cultas, con programas que reflejan las nuevas necesidades de la sociedad urbana del siglo XX. ABSTRACT The thesis is composed of a first part that is collected as introducing different views and definitions of popular architecture, the state of affairs, commenting on articles and publications carried out at the Mancha. The second part explores general issues before the main urban analysis of the thesis, with the following chapters: -A study of the geographic, historical, socio-economic and cultural conditions of the region of the Mancha Baja. Delimiting the territory -A tour with an overview of the province of Ciudad Real by regions. -A study of the different traditional building types, with examples in the region from the Mancha. -The Analysis of building materials, components and systems used in traditional buildings in the Mancha Lower The third part studies from the premise of the drawing: The urban planning of the towns to study and houses of Manzanares, from the execution of plans, elevations and sections, sites in the blocks, old photographs, a full description is made, covering a wide range of examples, highlighting the “evolution during the twentieth century, in its last quarter, buildings of popular character “, which is the ultimate aim of the thesis. In addition to reaching the conclusions drawn from the analysis cards of these buildings, the objectives pursued with this study would be also: This paper is the realization of a first rough work from the architectural vision of traditional architecture from the Mancha. To Search a work method for approaching the popular architecture, other than those made so far by other studies of historians, engineers and sociologists, with the graphical representation and the buildings would be studied like living organisms that evolve over time. To collect all the current information that It can be able to connect itself with the popular architecture in the region, and cite the writings and publications of reference for future studies. Geomorphology, climate, topography of the place is studied to obtain a key information about materials, construction techniques and morphology of the buildings. A section is opened to study the case of traditional industrial buildings like windmills, flour mill, pigeon lofts, public granary, threshing floor and cellars with the analysis of several examples; its importance is highlighted in the urban plan of the town. Finally a large block of popular literature on architecture is developed, consulted for work is distinct from the general existing on the subject. The popular architecture from the Mancha is built of rammed earth and roofs inclined of Arabic tiles, the buildings are closed to the outside, but they are open around large courtyards, and ground floor and camera high, with additional elements of protection, they are opened to patios. The manor has a complex program on agricultural and domestic activity. Large climate protection, poor decoration, quite primitive in shaping living spaces, and more structural scale in storage and processing units of agriculture-related products, mainly wine, cereal and to a lesser extent oil. These architecture combines the domestic and productive use, but which will evolve and they are distinguishing, both enclosed spaces such as courtyards. The buildings keep the same aesthetic qualities because they repeat shapes and volumes, but they maintain their spatial configuration individually; the materials, building techniques and architectural elements are repeated with slight variations, but there aren´t two identical houses. This architecture evolved from the block, basic and primitive house, with few examples in the most deprived towns, to the complex house, where agricultural units are clearly separated of domestic rooms. It developed from a country house (with the same patterns) whether it is located in the countryside or in the towns, to an urban house, in which we can find a parallel transformation, developing domestic programs, more specialized, mixed with cultivated architectures, with programs that reflect the changing needs of urban society of the twentieth century.
