Collaborative Engineering Paradigm Applied to the Aerospace Industry

Airbus designs and industrializes aircrafts using Concurrent Engineering techniques since decades. The introduction of new PLM methods, procedures and tools, and the need to reduce time-to-market, led Airbus Military to pursue new working methods. Traditional Engineering works sequentially. Concurrent Engineering basically overlaps tasks between teams. Collaborative Engineering promotes teamwork to develop product, processes and resources from the conceptual phase to the start of the serial production. The CALIPSO-neo pilot project was launched to support the industrialization process of a medium size aerostructure. The aim is to implement the industrial Digital Mock-Up (iDMU) concept and its exploitation to create shop floor documentation. In a framework of a collaborative engineering strategy, the project is part of the efforts to deploy Digital Manufacturing as a key technology for the industrialization of aircraft assembly lines. This paper presents the context, the conceptual approach and the methodology adopted.

Air Mines. Urban Space Station

Air Mines The sky over the city's port was the color of a faulty screen, only partly lit up. As the silhouette of nearby buildings became darker, but more clearly visible against the fading blur-filter of a background, the realization came about how persistent a change had been taking place. Slowly, old wooden water reservoirs and rattling HVAC systems stopped being the only inhabitants of roofs. Slightly trembling, milkish jellyfish-translucent air volumes had joined the show in multiples. A few years ago artists and architects seized upon the death of buildings as their life-saving media. Equipped with constructive atlases and instruments they started disemboweling their subjects, poking about their systems, dumping out on the street the battered ugliness of their embarrassing bits and pieces, so rightly hidden by facades and height from everyday view. But, would you believe it? Even ?old ladies?, investment bankers or small children failed to get upset. Of course, old ladies are not what they used to be. It was old ladies themselves that made it happen after years of fights with the town hall, imaginative proposals and factual arguments. An industry with little financial gains but lots of welcome externalities was not, in fact, the ground for investment bankers. But they too had to admit that having otherwise stately buildings make fine particulate pencils with their facades was not the worse that could happen. Yes, making soot pencils had been found an interesting and visible end product of the endeavor, a sort of mining the air for vintage writing tools one can actually touch. The new view from the street did not seem as solid or dignified as that of old, and they hated that the market for Fine Particulates Extraction (FPE, read efpee) had to be applied on a matrix of blocks and streets that prevented undue concentration of the best or worse solutions. It had to be an evenly distributed city policy in order for the city to apply for cleaning casino money. Once the first prototypes had been deployed in buildings siding Garden Avenue or Bulwark Street even fast movers appreciated the sidekick of flower and plant smell dripping down the Urban Space Stations (USS, read use; USSs, read uses) as air and walls cooled off for a few hours after sunset. Enough. It was all nice to remember, but it was now time to go up and start the lightweight afternoon maintenance of their USS. Coop discussions had taken place all through the planning and continued through the construction phase as to how maintenance was going to be organized. Fasters had voted for a pro, pay a small amount and let them use it for rent and produce. In the end some neighbors decided they were slow enough to take care and it was now the turn. Regret came periodically, sometimes a week before, and lasted until work actually started. But lately it had been replaced by anxiety when it needed to be passed over to the next caretaker. It did not look their shift was good enough and couldn?t wait to fix it. Today small preparations needed to be made for a class visit next day from a nearby cook school. They were frequenters. It had not been easy, but it shouldn?t have been that hard. In the end, even the easiest things are hard if they involve a city, buildings and neighbors. On the face of the data, the technicalities and the way final designs had been worked out for adaptation to the different settings, the decision of where to go was self evident, but organization issues and the ever-growing politics of taste in a city of already-gentrified-rodents almost put the project in the frozen orbit of timeless beautiful future possibilities. This is how it was. A series of designs by XClinic and OSS had made it possible to adapt to different building structures, leave in most cases the roof untouched and adapted a new technology of flexing fiberglass tubes that dissipated wind pressure in smooth bending.......

Desarrollo de una aplicación Web empresarial de ayuda a la producción de campañas publicitarias

La creación de esta aplicación web empresarial surge con la necesidad de optimizar el tiempo en el proceso de creación de una campaña publicitaria de email marketing. El objetivo principal de este trabajo es automatizar el proceso de validación de los campos de un formulario web. Un formulario web [6] es un documento digital en el que los usuarios introducen sus datos personales como nombre, apellido, dirección, documento de identidad, entre otros. Estos datos posteriormente serán procesados y almacenados en un base de datos para luego ser enviados al anunciante. El proceso de validación se refiere a la programación del formulario web en la parte del cliente usando tecnologías web como JavaScript y HTML5, para controlar que los datos introducidos por el usuario en el formulario, sean correctos. Cada campo de un formulario web tiene una validación específica que depende de varios factores, como son el país de lanzamiento de la campaña y el campo a validar. De esta forma dependiendo del tipo de validación se genera un fichero JavaScript con todas las validaciones de dicho formulario. Una de las finalidades de este trabajo es que cualquier usuario de la empresa pueda programar un formulario web, sin tener conocimientos previos de programación, ya que la programación se realiza de forma transparente al usuario. Este es un resumen básico de la aplicación web, sin embargo se debe tener en cuenta una serie de requisitos y parámetros para hacerlo más eficiente y personalizable dependiendo de las necesidades del producto final de cada campaña publicitaria. Todos estos aspectos se explicaran en detalle en los siguientes apartados. Este trabajo se realizó en el corporativo Media Response Group, para la empresa Canalmail S.L, situada en Alcobendas, supervisado por los tutores profesionales Daniel Paz y Jorge Lázaro Molina y por el tutor académico Rafael Fernández Gallego de la Universidad Politécnica de Madrid.---ABSTRACT---The creation of this enterprise Web application arises from the need to optimize the time in the process of creating an online advertising campaign. The main objective of this work is to automate the process of validating fields in a web form. A web form [6] is a digital document that users enter data such as name, surname, address, ID number among others. These data will subsequently be processed and stored in a database and then be sent to the client. These data will subsequently be processed and stored in a database and then be sent to the advertiser. This validation process refers to programming the online form on the client‟s side using web technologies such as JavaScript, HTML5 to control that the data entered by the user in this form are correct. Each field in a web form has a specific validation that depends on several factors; like being a nationwide launch of the campaign and validating data, thus depending on the type of validation a JavaScript file is generated with all validation web form. This file is integrated into the web form by calling the service. One purpose of this work is that any business user can program a web form, without prior knowledge of web programming, since programming is transparent to the user. This is a basic summary of the web application; however we must consider a number of requirements and parameters to make it more efficient and customizable depending on the needs of the end product of each advertising campaign. All these aspects are explained in detail in the following sections. This work was performed in the corporate Media Response Group, for the company Canalmail S.L, located in Alcobendas, supervised by professional tutors Daniel Paz and Jorge Lázaro Molina and PhD Assistant Lecturer at Universidad Politécnica de Madrid.

A component- and connector-based approach for end-user composite web applications development

Enabling real end-user development is the next logical stage in the evolution of Internet-wide service-based applications. Successful composite applications rely on heavyweight service orchestration technologies that raise the bar far above end-user skills. This weakness can be attributed to the fact that the composition model does not satisfy end-user needs rather than to the actual infrastructure technologies. In our opinion, the best way to overcome this weakness is to offer end-to-end composition from the user interface to service invocation, plus an understandable abstraction of building blocks and a visual composition technique empowering end users to develop their own applications. In this paper, we present a visual framework for end users, called FAST, which fulfils this objective. FAST implements a novel composition model designed to empower non-programmer end users to create and share their own self-service composite applications in a fully visual fashion. We projected the development environment implementing this model as part of the European FP7 FAST Project, which was used to validate the rationale behind our approach.

Caracterización y análisis comparativo del comportamiento medioambiental de los materiales de aislamiento térmico utilizados en la envolvente del edificio, en función del sistema constructivo y de la situación geográfica

La construcción es uno de los causantes de mayor impacto ambiental y energético en el entorno. Por ello, los profesionales del sector deben empezar a cambiar la manera en la que diseñan la arquitectura, incorporando técnicas y parámetros sostenibles desde las primeras etapas del diseño, controlando la elección de los materiales y las soluciones constructivas. A través de las Declaraciones Ambientales de Producto (DAP) es posible conocer el perfil ambiental de los productos de la construcción, sin embargo, la mayoría de estos documentos solo poseen información de la etapa de producto (A1-A3) y de la etapa de fin de vida, contemplando solo un tipo de tratamiento (vertedero o incineración). Lo que propone esta investigación es generar información medioambiental del resto de las etapas del ciclo de vida relacionado con el producto, haciendo especial hincapié en la etapa de transporte (A4), puesta en obra (A5), transporte de obra a planta de tratamiento (C2) y etapa de fin de vida con vertedero e incineración. Para la realización de la investigación se ha generado un Inventario de Ciclo de Vida (ICV) con valores medios facilitados por las empresas. El ámbito de actuación es la península ibérica, considerándose un transporte en camión. La evaluación ambiental se ha realizado con la herramienta informática SimaPro (versión 7.3.3). Para los procesos que no han podido ser modelizados por falta de información, se ha recurrido a la base de datos Ecoinvent (versión 2.0). Las categorías de impacto analizadas son las contempladas en la UNE-EN ISO 15804+A1. Con esta investigación se propone una catalogación medioambiental del material de aislamiento térmico según los impactos asociados al transporte, puesta en obra y fin de vida del producto para que el prescriptor pueda escoger qué material es el más adecuado a incorporar en el proyecto, desde el punto de vista medioambiental. ABSTRACT _ Construction is one of the main causes of environmental and energy impacts in the environment. Therefore, the professionals of the sector should begin changing the way they design architecture, incorporating sustainable techniques and parameters from the first design stages, controlling the choice of materials and building solutions. It is possible to know the environmental profile of construction products through Environmental Product Declarations (EPD). However, most of these documents only provide information for the product stage (A1-A3) and the end-of-life stage, taking into account only one type of treatment (landfill or incineration). This research proposes the generation of environmental information for the rest of the life cycle stages related to the product, with particular emphasis on the transportstage (A4), construction installation (A5), transport from the construction site to the recycling facilities (C2) and end-of-life stage with landfill and incineration. A Life Cycle Inventory (LCI) has been generated for the development of the research, with mean values provided by the firms. The scope of action is the Iberian Peninsula, considering transport by lorry. The environmental assessment has been carried out with the SimaPro software (version 7.3.3). The Ecoinvent database (version 2.0) has been used for the processes that couldn’t be modelled due to lack of information. The impact categories analysed are those considered in standard UNE-EN ISO 15804+A1. This research proposes an environmental cataloguing of the thermal insulation material depending on the impacts associated with transport, construction installation and end-of-life of the product so that the prescriber might choose which material is the most suitable to implement in the project from an environmental point of view.
