Plataforma Tecnológica Colaborativa Comunidad de Negocios San Antonio, Chile, red de aprovisionamiento local: OpenSupply

El proyecto que se quiere plantear es la creación de una Plataforma electrónica a través de la cual se pretende agrupar a los diferentes proveedores que intervienen en la cadena de abastecimiento de la comunidad logística de San Antonio, abriendo la posibilidad de participación de empresas grandes y pequeñas y más aun promoviendo la creación de las mismas por parte de los ciudadanos de la región, de esta manera, se eliminan las brechas asimétricas existentes entre la oferta y la demanda permitiendo que las empresas medianas y grandes accedan a ofertas y transacciones con empresas proveedoras medianas y pequeñas. Dicho proyecto, tiene como objetivo general el consolidar los procesos de abastecimiento implementados por las empresas a través de la organización y estandarización de los mismos mediante el uso del portal, planteado en el presente proyecto, como apoyo tecnológico. Existen dos conceptos básicos a analizar de manera teórica dentro del proyecto, el primero de ellos es el de clúster logístico-portuario, lo cuales son reconocidos como instrumentos importantes para el progreso del desarrollo industrial, innovación, competitividad y crecimiento, tomando como ejemplos a los puertos de Valencia y Long Beach en la ciudad de Los Ángeles. El segundo concepto es el de E-Procurement, el cual se desarrolla siguiendo los pasos básicos de una cadena de abastecimiento tradicional, sin embargo, lo que genera un cambio real dentro de los procesos es el hecho que los procesos de cotización y seguimiento de proveedores se van a llevar a cabo a través de una plataforma electrónica con base a las evaluaciones que se llevan a cabo por parte de las empresas demandantes de los productos o servicios ofrecidos por las compañías proveedoras. (Renko, 2011) De la misma manera, se tomaran varios proyectos de e-procurement desarrollados a nivel mundial como base comparativa y de apoyo para el presente proyecto tales como: HYDRA: Es un sistema que tiene su soporte en la web, el cual es orientado “en el medio” lo cual lo hace un sistema con una arquitectura híbrida, que posee tanto un diseño en capas como una estructura comprensiva para desarrollar integración de negocios, colaboración y monitoreo en la gestión de la cadena de suministro (Renko, 2011) IPT: BidNet ha proporcionado servicios de oferta de información a miles de proveedores y compradores de bienes en el ámbito gubernamental por más de 25 años. (Bidnet, 2013) E-BUYPLACE: E-buyplace.com es el 1° especialista en SupplierRelationship Management que ha desarrollado un original y singular SRM 100% a través de Internet. (e-buyplace, 2013) RosettaNet: La iniciativa RosettaNet anima a optimizar los procesos de la cadena de suministro mediante el establecimiento, implementación y promoción de estándares abiertos en el mercado e-Business (AQS, Advance Quality Solutions, 2002)

Application of computer-aided facilities management (CAFM) for intelligent buildings operation

Purpose – The purpose of this paper is to investigate the concepts of intelligent buildings (IBs), and the opportunities offered by the application of computer-aided facilities management (CAFM) systems. Design/methodology/approach – In this paper definitions of IBs are investigated, particularly definitions that are embracing open standards for effective operational change, using a questionnaire survey. The survey further investigated the extension of CAFM to IBs concepts and the opportunities that such integrated systems will provide to facilities management (FM) professionals. Findings – The results showed variation in the understanding of the concept of IBs and the application of CAFM. The survey showed that 46 per cent of respondents use a CAFM system with a majority agreeing on the potential of CAFM in delivery of effective facilities. Research limitations/implications – The questionnaire survey results are limited to the views of the respondents within the context of FM in the UK. Practical implications – Following on the many definitions of an IB does not necessarily lead to technologies of equipment that conform to an open standard. This open standard and documentation of systems produced by vendors is the key to integrating CAFM with other building management systems (BMS) and further harnessing the application of CAFM for IBs. Originality/value – The paper gives experience-based suggestions for both demand and supply sides of the service procurement to gain the feasible benefits and avoid the currently hindering obstacles, as the paper provides insight to the current and future tools for the mobile aspects of FM. The findings are relevant for service providers and operators as well.

Ocean data dissemination: new challenges for data integration

In the decade since OceanObs `99, great advances have been made in the field of ocean data dissemination. The use of Internet technologies has transformed the landscape: users can now find, evaluate and access data rapidly and securely using only a web browser. This paper describes the current state of the art in dissemination methods for ocean data, focussing particularly on ocean observations from in situ and remote sensing platforms. We discuss current efforts being made to improve the consistency of delivered data and to increase the potential for automated integration of diverse datasets. An important recent development is the adoption of open standards from the Geographic Information Systems community; we discuss the current impact of these new technologies and their future potential. We conclude that new approaches will indeed be necessary to exchange data more effectively and forge links between communities, but these approaches must be evaluated critically through practical tests, and existing ocean data exchange technologies must be used to their best advantage. Investment in key technology components, cross-community pilot projects and the enhancement of end-user software tools will be required in order to assess and demonstrate the value of any new technology.

Estudio sobre un sistema de radiocomunicaciones ferroviarias de acuerdo al paradigma 4G

No hay duda de que el ferrocarril es uno de los símbolos del avance tecnológico y social de la humanidad, y su imparable avance desde el primer tercio del Siglo XIX así lo atestigua. No obstante, a lo largo de gran parte de su historia se ha mostrado algo renuente a abrazar ciertas tecnologías, lo que le ha causado ser tachado de conservador. Sin embargo, en los últimos años, coincidiendo con el auge masivo de los trenes de alta velocidad, los metropolitanos y los tranvías, muchas tecnologías han ido penetrando en el mundo del ferrocarril. La que hoy nos ocupa es una de las que mayor valor añadido le ha proporcionado (y que probablemente le proporcionará también en el futuro): las comunicaciones móviles. Actualmente el uso de este tipo de tecnologías en el entorno ferroviario puede calificarse como de inicial o, por seguir la nomenclatura de las comunicaciones móviles públicas, de segunda generación. El GSM-R en las líneas de alta velocidad es un caso (aunque de éxito al fin y al cabo) que define perfectamente el estado del arte de las comunicaciones móviles en este entorno, ya que proporcionó un gran valor añadido a costa de un gran esfuerzo de estandarización; ha supuesto un importante salto adelante en el campo de la fiabilidad de este tipo de sistemas, aunque tiene unas grandes limitaciones de capacidad y graves problemas de escalabilidad. Todo hace pensar que en 2025 el sustituto de GSM-R deberá estar en el mercado. En cualquier caso, se debería abandonar la filosofía de crear productos de nicho, que son extraordinariamente caros, y abrazar las filosofías abiertas de las redes de comunicaciones públicas. Aquí es donde LTE, la última gran estrella de esta familia de estándares, puede aportar mucho valor. La idea subyacente detrás de esta Tesis es que LTE puede ser una tecnología que aporte gran valor a las necesidades actuales (y probablemente futuras) del sector del ferrocarril, no solamente en las líneas y trenes de alta velocidad, sino en las denominadas líneas convencionales y en los metros y tranvías. Dado que es un campo aún a día de hoy que dista bastante de estar completamente estudiado, se ha explorado la problemática de la propagación electromagnética en los diferentes entornos ferroviarios, como pueden ser los túneles de metro y la influencia de las estructuras de los trenes. En este sentido, se ha medido de forma bastante exhaustiva en ambos entornos. Por otro lado, dado que los sistemas multiantena son uno de los pilares fundamentales de los modernos sistemas de comunicaciones, se ha verificado de forma experimental la viabilidad de esta tecnología a la hora de implementar un sistema de comunicaciones trentierra en un túnel. Asimismo, de resultas de estas medidas, se ha comprobado la existencia de ciertos fenómenos físicos que pueden suponer una merma en la eficiencia de este tipo de sistemas. En tercer lugar, y dado que uno de los grandes desafíos de las líneas de alta velocidad está provocado por la gran celeridad a la que se desplazan los trenes, se ha explorado la influencia de este parámetro en la eficiencia global de una red completa de comunicaciones móviles. Por supuesto, se ha hecho especial hincapié en los aspectos relacionados con la gestión de la movilidad (traspasos o handovers Por último, a modo de cierre de la Tesis, se ha tratado de identificar los futuros servicios de comunicaciones que aportarán más valor a las explotaciones ferroviarias, así como los requisitos que supondrán para las redes de comunicaciones móviles. Para los casos antes enunciados (propagación, sistemas multiantena, movilidad y desafíos futuros) se proporcionan las contribuciones ya publicadas en revistas y congresos internacionales, así como las que están enviadas para su revisión. ABSTRACT There is almost no doubt that railways are one of the symbols of the technological and social progress of humanity. However, most of the time railways have been somewhat reluctant to embrace new technologies, gaining some reputation of being conservative. But in the last years, together with the massive boom of high speed lines, subways and trams all over the world, some technologies have broken through these conservative resistance. The one which concerns us now is one of the most value-added (both today and in the future): mobile communications. The state-of-the-art of these technologies in the railway field could be called as incipient, or (following the mobile communications’ notation) ‘second generation’. GSM-R, the best example of mobile communications in railways is a success story that shows perfectly the state-of-the-art of this field: it provided a noticeable mark-up but also required a great standardization effort; it also meant a huge step forward in the reliability of these systems but it also needs to face some scalability issues and some capacity problems. It looks more than feasible that in 2025 the alternative to GSM-R should be already available. Anyway, the vision here should be forgetting about expensive niche products, and embracing open standards like public mobile communications do. The main idea behind this Thesis is that LTE could be a technology that provides a lot of added value to the necessities of the railways of today and the future. And not only to highspeed lines, but also to the so-called conventional rail, subways and tramways. Due to the fact that even today, propagation in tunnels and influence of car bodies is far from being full-studied, we measured in a very exhaustive way the EM propagation in these two environments. Also, multiantenna systems are one of the basic foundations of the modern communications systems, so we experimentally verified the feasibility of using such a system in a train-towayside in a tunnel. Moreover, from the measurements carried out we proved the existence of some physical phenomena that could imply a decrease in the performance of these multiantenna systems. In third place, we have explored the influence of high-speed in the whole performance of the network, from the mobility management point-of-view. This high-speed movement is one of the most relevant challenges for the mobile communications networks. The emphasis was placed on the mobility aspects of the radio resource management. Finally, the Thesis closure is an identification of the future communication services that could provide a bigger addition of value to railways, and also the requirements that imply to mobile communications networks. For all the previous for scenarios depicted before (propagation, multiantenna systems, mobility and challenges) we provide some contributions already published (or submitted for revision or still in progress) on publications and international conferences.

Data driven graphical applications:a fluid approach

The inclusion of high-level scripting functionality in state-of-the-art rendering APIs indicates a movement toward data-driven methodologies for structuring next generation rendering pipelines. A similar theme can be seen in the use of composition languages to deploy component software using selection and configuration of collaborating component implementations. In this paper we introduce the Fluid framework, which places particular emphasis on the use of high-level data manipulations in order to develop component based software that is flexible, extensible, and expressive. We introduce a data-driven, object oriented programming methodology to component based software development, and demonstrate how a rendering system with a similar focus on abstract manipulations can be incorporated, in order to develop a visualization application for geospatial data. In particular we describe a novel SAS script integration layer that provides access to vertex and fragment programs, producing a very controllable, responsive rendering system. The proposed system is very similar to developments speculatively planned for DirectX 10, but uses open standards and has cross platform applicability. © The Eurographics Association 2007.

WSRF-based modeling of clinical trial information for collaborative cancer research

The CancerGrid consortium is developing open-standards cancer informatics to address the challenges posed by modern cancer clinical trials. This paper presents the service-oriented software paradigm implemented in CancerGrid to derive clinical trial information management systems for collaborative cancer research across multiple institutions. Our proposal is founded on a combination of a clinical trial (meta)model and WSRF (Web Services Resource Framework), and is currently being evaluated for use in early phase trials. Although primarily targeted at cancer research, our approach is readily applicable to other areas for which a similar information model is available.

INTAMAP: an interoperable automated interpolation web service

INTAMAP is a web processing service for the automatic interpolation of measured point data. Requirements were (i) using open standards for spatial data such as developed in the context of the open geospatial consortium (OGC), (ii) using a suitable environment for statistical modelling and computation, and (iii) producing an open source solution. The system couples the 52-North web processing service, accepting data in the form of an observations and measurements (O&M) document with a computing back-end realized in the R statistical environment. The probability distribution of interpolation errors is encoded with UncertML, a new markup language to encode uncertain data. Automatic interpolation needs to be useful for a wide range of applications and the algorithms have been designed to cope with anisotropies and extreme values. In the light of the INTAMAP experience, we discuss the lessons learnt.

Lessons learned from INTAMAP, an interoperable web service for the real-time interpolation of environmental variables

Interpolated data are an important part of the environmental information exchange as many variables can only be measured at situate discrete sampling locations. Spatial interpolation is a complex operation that has traditionally required expert treatment, making automation a serious challenge. This paper presents a few lessons learnt from INTAMAP, a project that is developing an interoperable web processing service (WPS) for the automatic interpolation of environmental data using advanced geostatistics, adopting a Service Oriented Architecture (SOA). The “rainbow box” approach we followed provides access to the functionality at a whole range of different levels. We show here how the integration of open standards, open source and powerful statistical processing capabilities allows us to automate a complex process while offering users a level of access and control that best suits their requirements. This facilitates benchmarking exercises as well as the regular reporting of environmental information without requiring remote users to have specialized skills in geostatistics.

INTAMAP: the design and implementation of an interoperable automated interpolation web service

INTAMAP is a Web Processing Service for the automatic spatial interpolation of measured point data. Requirements were (i) using open standards for spatial data such as developed in the context of the Open Geospatial Consortium (OGC), (ii) using a suitable environment for statistical modelling and computation, and (iii) producing an integrated, open source solution. The system couples an open-source Web Processing Service (developed by 52°North), accepting data in the form of standardised XML documents (conforming to the OGC Observations and Measurements standard) with a computing back-end realised in the R statistical environment. The probability distribution of interpolation errors is encoded with UncertML, a markup language designed to encode uncertain data. Automatic interpolation needs to be useful for a wide range of applications and the algorithms have been designed to cope with anisotropy, extreme values, and data with known error distributions. Besides a fully automatic mode, the system can be used with different levels of user control over the interpolation process.

Developing a forest data portal to support multi-scale decision making

Forests play a pivotal role in timber production, maintenance and development of biodiversity and in carbon sequestration and storage in the context of the Kyoto Protocol. Policy makers and forest experts therefore require reliable information on forest extent, type and change for management, planning and modeling purposes. It is becoming increasingly clear that such forest information is frequently inconsistent and unharmonised between countries and continents. This research paper presents a forest information portal that has been developed in line with the GEOSS and INSPIRE frameworks. The web portal provides access to forest resources data at a variety of spatial scales, from global through to regional and local, as well as providing analytical capabilities for monitoring and validating forest change. The system also allows for the utilisation of forest data and processing services within other thematic areas. The web portal has been developed using open standards to facilitate accessibility, interoperability and data transfer.
