    Full text link
    Nowadays agile software development is used in greater extend but for small organizations only, whereas MDA is suitable for large organizations but yet not standardized. In this paper the pros and cons of Model Driven Architecture (MDA) and Extreme programming have been discussed. As both of them have some limitations and cannot be used in both large scale and small scale organizations a new architecture has been proposed. In this model it is tried to opt the advantages and important values to overcome the limitations of both the software development procedures. In support to the proposed architecture the implementation of it on Online Polling System has been discussed and all the phases of software development have been explained.Comment: 14 pages,1 Figure,1 Tabl

    358 p.El sector de la biotecnología demanda innovación constante para hacer frente a los retos del sector sanitario. Hechos como la reciente pandemia COVID-19, el envejecimiento de la población, el aumento de las tasas de dependencia o la necesidad de promover la asistencia sanitaria personalizada tanto en entorno hospitalario como domiciliario, ponen de manifiesto la necesidad de desarrollar dispositivos médicos de monitorización y diagnostico cada vez más sofisticados, fiables y conectados de forma rápida y eficaz. En este escenario, los sistemas embebidos se han convertido en tecnología clave para el diseño de soluciones innovadoras de bajo coste y de forma rápida. Conscientes de la oportunidad que existe en el sector, cada vez son más las denominadas "biotech start-ups" las que se embarcan en el negocio de los dispositivos médicos. Pese a tener grandes ideas y soluciones técnicas, muchas terminan fracasando por desconocimiento del sector sanitario y de los requisitos regulatorios que se deben cumplir. La gran cantidad de requisitos técnicos y regulatorios hace que sea necesario disponer de una metodología procedimental para ejecutar dichos desarrollos. Por ello, esta tesis define y valida una metodología para el diseño y desarrollo de dispositivos médicos embebidos

    Computer Integrated Construction (CIC) systems are computer environments through which collaborative working can be undertaken. Although many CIC systems have been developed to demonstrate the communication and collaboration within the construction projects, the uptake of CICs by the industry is still inadequate. This is mainly due to the fact that research methodologies of the CIC development projects are incomplete to bridge the technology transfer gap. Therefore, defining comprehensive methodologies for the development of these systems and their effective implementation on real construction projects is vital. Requirements Engineering (RE) can contribute to the effective uptake of these systems because it drives the systems development for the targeted audience. This paper proposes a requirements engineering approach for industry driven CIC systems development. While some CIC systems are investigated to build a broad and deep contextual knowledge in the area, the EU funded research project, DIVERCITY (Distributed Virtual Workspace for Enhancing Communication within the Construction Industry), is analysed as the main case study project because its requirements engineering approach has the potential to determine a framework for the adaptation of requirements engineering in order to contribute towards the uptake of CIC systems

    Ontology engineering methodologies tend to emphasize the role of the knowledge engineer or require a very active role of domain experts. In this paper, a participatory ontology engineering method is described that holds the middle ground between these two 'extremes'. After thorough ethnographic research, an interdisciplinary group of domain experts closely interacted with ontology engineers and social scientists in a series of workshops. Once a preliminary ontology was developed, a dynamic care request system was built using the ontology. Additional workshops were organized involving a broader group of domain experts to ensure the applicability of the ontology across continuous care settings. The proposed method successfully actively engaged domain experts in constructing the ontology, without overburdening them. Its applicability is illustrated by presenting the co-created continuous care ontology. The lessons learned during the design and execution of the approach are also presented

    Contribution to Software Development Method based on Generalized Requirement Approach

    Requirements’ gathering is one of the first steps in the software development process. Gathering business requirements, when the final product requirements are dictated by a known client, can be a difficult process. Even if the client knows their own business best, often their idea about a new business product is obscure, and described by general terms that contribute very much to common misunderstandings among the participants. Business requirement verification when the requirements are gathered using text and graphics can be a slow, error-prone, and expensive process. Misunderstandings and omitted requirements cause the need for revisions and increase project costs and delays. This research work proposes a new approach to the business software development process and is focused on the client’s understanding of how the business software development process works as well as a demonstration of the business requirement practices during requirement negotiation process. While the current software development process validates the business requirement at the end of the development process, this method implementation enables business requirement validation during the requirement negotiation phase. The process of the business requirement negotiation is guided by a set of predefined questions. These questions are guidelines for specifying a sufficient level of requirement details for generating executable code that is able to demonstrate each requirement. Effective implementation of the proposed method requires employment of the GRA Framework. Besides providing guidelines for requirement specification, the Framework shall create executable and provide the test environment for a requirement demonstration. This dissertation implements an example framework that is built around a central repository. Stored within the repository is the data collected during the requirement negotiations process. Access to the repository is managed by a Web interface that enables a collaborative and paperless environment. The result is that the data is stored in one place and updates are reflected to the stakeholders immediately. The executable code is generated by the Generator, a module that provides general programming units that are able to create source code files, databases, SQL statements, classes and methods, navigation menus, and demo applications, all from the data stored in the data repository. The generated software can then be used for the business requirement demonstration. This method assumes that any further development process is built around the requirements repository, which can provide continuous tracking of implementation changes. Besides readily documenting, tracking, and validating the requirements, this method addresses multiple requirement management syndromes such as the insufficient requirements description details provision, the IKIWISI (“I’ll know it when I see it”) Syndrome, the Yes, But Syndrome (“That is not exactly what I mean”), and the Undiscovered Ruins Syndrome (“Now that I see it, I have another requirement to add”).

    Rapid advances in automation has disrupted and transformed several industries in the past 25 years. Automation has evolved from regulation and control of simple systems like controlling the temperature in a room to the autonomous control of complex systems involving network of systems. The reason for automation varies from industry to industry depending on the complexity and benefits resulting from increased levels of automation. Automation may be needed to either reduce costs or deal with hazardous environment or make real-time decisions without the availability of humans. Space autonomy, Internet, robotic vehicles, intelligent systems, wireless networks and power systems provide successful examples of various levels of automation. NASA is conducting research in autonomy and developing plans to increase the levels of automation in aviation operations. This paper provides a brief review of levels of automation, previous efforts to increase levels of automation in aviation operations and current level of automation in the various tasks involved in aviation operations. It develops a methodology to assess the research and development in modeling, sensing and actuation needed to advance the level of automation and the benefits associated with higher levels of automation. Section II describes provides an overview of automation and previous attempts at automation in aviation. Section III provides the role of automation and lessons learned in Space Autonomy. Section IV describes the success of automation in Intelligent Transportation Systems. Section V provides a comparison between the development of automation in other areas and the needs of aviation. Section VI provides an approach to achieve increased automation in aviation operations based on the progress in other areas. The final paper will provide a detailed analysis of the benefits of increased automation for the Traffic Flow Management (TFM) function in aviation operations
