Desing and Validation of a Light Inference System to Support Embedded Context Reasoning

Embedded context management in resource-constrained devices (e.g. mobile phones, autonomous sensors or smart objects) imposes special requirements in terms of lightness for data modelling and reasoning. In this paper, we explore the state-of-the-art on data representation and reasoning tools for embedded mobile reasoning and propose a light inference system (LIS) aiming at simplifying embedded inference processes offering a set of functionalities to avoid redundancy in context management operations. The system is part of a service-oriented mobile software framework, conceived to facilitate the creation of context-aware applications—it decouples sensor data acquisition and context processing from the application logic. LIS, composed of several modules, encapsulates existing lightweight tools for ontology data management and rule-based reasoning, and it is ready to run on Java-enabled handheld devices. Data management and reasoning processes are designed to handle a general ontology that enables communication among framework components. Both the applications running on top of the framework and the framework components themselves can configure the rule and query sets in order to retrieve the information they need from LIS. In order to test LIS features in a real application scenario, an ‘Activity Monitor’ has been designed and implemented: a personal health-persuasive application that provides feedback on the user’s lifestyle, combining data from physical and virtual sensors. In this case of use, LIS is used to timely evaluate the user’s activity level, to decide on the convenience of triggering notifications and to determine the best interface or channel to deliver these context-aware alerts.d

Desing of an Airport Surface Routing Evaluation Tool

There are many studies related with airport surface routing algorithms, based on different approaches and with different evaluation methods and metrics. So, the need of performing a balanced analysis and comparison using a common framework is evident. This paper presents an implementation of an evaluation tool for airport surface routing algorithms. The routing evaluation tool presented here is based in three basic pillars composed by the airport model, the model and generation of traffic and a comprehensive figure of merit function. The paper includes some example evaluations performed over Barajas Airport with representative traffic samples using several simple routing methods.

Technical criteria for the desing of foundation slabs and perimetral wall in difficult terrain in Madrid. Spain

This paper explains a procedure for the choice of ballast modules used for the design of direct continuous foundation in karst terrain. The presence of dangerous cavities is introduced in this procedure thereby evaluating risk failure. It also provides pertinent guidelines to direct the geotechnical survey of the terrain.

Desing and development of a robotic platform for the evaluation of search algorithms

Plant diseases represent a major economic and environmental problem in agriculture and forestry. Upon infection, a plant develops symptoms that affect different parts of the plant causing a significant agronomic impact. As many such diseases spread in time over the whole crop, a system for early disease detection can aid to mitigate the losses produced by the plant diseases and can further prevent their spread [1]. In recent years, several mathematical algorithms of search have been proposed [2,3] that could be used as a non-invasive, fast, reliable and cost-effective methods to localize in space infectious focus by detecting changes in the profile of volatile organic compounds. Tracking scents and locating odor sources is a major challenge in robotics, on one hand because odour plumes consists of non-uniform intermittent odour patches dispersed by the wind and on the other hand because of the lack of precise and reliable odour sensors. Notwithstanding, we have develop a simple robotic platform to study the robustness and effectiveness of different search algorithms [4], with respect to specific problems to be found in their further application in agriculture, namely errors committed in the motion and sensing and to the existence of spatial constraints due to land topology or the presence of obstacles.

Competencias genericas en ingeniería: un estudio comparado en el contexto internacional

En este trabajo se comparan las codificaciones de competencias del Plan de estudios de CDIO (Conceive, Desing, Implement and Operate systems in the enterprise and societal context) con las definidas por el Proyecto Tuning y las de IPMA (International Project Management Asociation). También se determina el tipo de aprendizaje más apropiado para lograr la adquisición de competencias en la formación de los ingenieros y se revisa la evolución de los programas de ingeniería industrial en Perú, España y EE.UU para definir las competencias específicas aplicables al caso peruano. La codificación de CDIO responde a los estándares de acreditación de ABET (Accreditation Board for Engineering and Technology) y las competencias del Proyecto Tuning son las definidas para Latinoamérica. Se comparan las competencias definidas en los estándares de acreditación ABET en el ámbito de las ingenierías, con las competencias internacionales según el modelo IPMA. Los resultados evidencian la necesidad de aplicar modelos holísticos que abarquen competencias técnicas, contextuales y de comportamiento en los planes de estudio de ingeniería, su pertinencia para la definición de programas de ingeniería en Latinoamérica y la posibilidad de definir un plan de estudios de ingeniería industrial con una estrategia de aprendizaje apropiada.

Estudio comparativo en el dimensionamiento de cimentaciones

El presente documento es el resultado de la participación de forma activa del autor en el equipo de la oficina de proyectos IDEAM S.A. encargada de realizar en U.T.E. con F.H.E.C.O.R. un manual de aplicación del Eurocódigo 7 a petición de la Dirección General de Carreteras del Ministerio de Fomento. El trabajo se ha centrado en la comparación entre las diversas formulaciones existentes para obtener la carga de hundimiento en cimentaciones superficiales, comparando los resultados de los distintos factores que participan en la formulación de los diferentes autores. De este modo el estudio ha servido para detectar algunas incongruencias entre las formulaciones clásicas de Brinch-Hansen y la formulación propuesta en el anexo D del Eurocódigo 7 (UNE-EN 1997-1) A sí mismo la investigación también se centra en las implicaciones que supone realizar el diseño de las cimentaciones superficiales utilizando para ello el método de los coeficientes parciales de seguridad y combinaciones de acciones mayoradas tal y como plantea el Eurocódigo 7 en lugar de realizar dicho diseño mediante el método de los coeficientes globales de seguridad y combinaciones características de acciones en la forma en que la tradición geotécnica española ha venido haciendo hasta la fecha. This document is the result of the active participation of the author in IDEAM SA, responsible for compiling a guide for the Eurocode 7 as a request by General Director of Hihways of the Fomento Ministry The work primarily focuses on the comparison between the different theories used to obtain the bearing capacity of shallow foundations and comparing the results of the multpile factors involved in the formulas designed by different authors Thereby, the present study has helped identify inconsistencies between the classical formulations of Brinch-Hansen and the proposed formulation in the Annex D of the Eurocode 7 (UNE- EN 1997-1) The investigation additionally focuses on the implications of shallow foundations desing by using the method of partial safety factors and the ULS combinations of actions instead of employing the design by the global safety factor method and SLS combinations of the actions.
