Heart Failure Monitoring System Based on Wearable and Information Technologies

In Europe, Cardiovascular Diseases (CVD) are the leading source of death, causing 45% of all deceases. Besides, Heart Failure, the paradigm of CVD, mainly affects people older than 65. In the current aging society, the European MyHeart Project was created, whose mission is to empower citizens to fight CVD by leading a preventive lifestyle and being able to be diagnosed at an early stage. This paper presents the development of a Heart Failure Management System, based on daily monitoring of Vital Body Signals, with wearable and mobile technologies, for the continuous assessment of this chronic disease. The System makes use of the latest technologies for monitoring heart condition, both with wearable garments (e.g. for measuring ECG and Respiration); and portable devices (such as Weight Scale and Blood Pressure Cuff) both with Bluetooth capabilities

MIRACLE’s Hybrid Approach to Bilingual and Monolingual Information Retrieval

The main goal of the bilingual and monolingual participation of the MIRACLE team in CLEF 2004 was to test the effect of combination approaches on information retrieval. The starting point was a set of basic components: stemming, transformation, filtering, generation of n-grams, weighting and relevance feedback. Some of these basic components were used in different combinations and order of application for document indexing and for query processing. A second order combination was also tested, mainly by averaging or selective combination of the documents retrieved by different approaches for a particular query.

These experiments combine different basic techniques, linguistic-oriented and statistic-oriented, to be applied to the indexing and retrieval processes.

A Tele-Health Communication and Information System for Underserved Children in Rural Areas of Nicaragua

Millennium Development Goals point out the necessity of actively promoting maternal-child health care status, especially in underserved areas. This article details the development actions carried out between 2008 and 2011 in some rural communities of Nicaragua with the aim to provide a low-cost tele-health communication service. The service is managed by the health care center of Cusmapa, which leads the program and maintains a communication link between its health staff and the health brigades of 26 distant communities. Local agents can use the system to report urgent maternal-child health care episodes to be assessed through WiMAX-WiFi voice and data communications attended by two physicians and six nurses located at the health care center. The health and nutritional status of the maternal-child population can be monitored to prevent diseases, subnutrition, and deaths. The action approach assumes the fundamentals of appropriate technology and looks for community- based, sustainable, replicable, and scalable solutions to ensure future deployments according to the strategies of the United Nations.

A Model-Based Monitoring Architecture for Heterogeneous Enterprise Services and Information Systems

Runtime management of distributed information systems is a complex and costly activity. One of the main challenges that must be addressed is obtaining a complete and updated view of all the managed runtime resources. This article presents a monitoring architecture for heterogeneous and distributed information systems. It is composed of two elements: an information model and an agent infrastructure. The model negates the complexity and variability of these systems and enables the abstraction over non-relevant details. The infrastructure uses this information model to monitor and manage the modeled environment, performing and detecting changes in execution time. The agents infrastructure is further detailed and its components and the relationships between them are explained. Moreover, the proposal is validated through a set of agents that instrument the JEE Glassfish application server, paying special attention to support distributed configuration scenarios.

Knowledge Management and Information Systems based on Workflow Technology

Knowledge management is critical for the success of virtual communities, especially in the case of distributed working groups. A representative example of this scenario is the distributed software development, where it is necessary an optimal coordination to avoid common problems such as duplicated work. In this paper the feasibility of using the workflow technology as a knowledge management system is discussed, and a practical use case is presented. This use case is an information system that has been deployed within a banking environment. It combines common workflow technology with a new conception of the interaction among participants through the extension of existing definition languages.

Tools in Spanish Universities to facilitate the transmission from High School to University and their assessment.

Incoming students in the University have education deficiencies, so universities studies require a sound basis of scientific knowledge. In this project are analysed instruments to reinforcing knowledge in those areas related to the studies that students are about to embark on public Spanish universities. There are important differences among universities and, in each university there are great differences among titles. Initial courses (cursos cero) are widespread (in 50% of universities) that selfevaluation instruments (14 % of universities). It is necessary to improve diffusion of those instruments because it is not possible to evaluate them. So are proposed the next actuations: to make regular standard surveys for professors and students; to publish results of surveys; public universities should institutionalize their basic training offer and improve the dissemination of this offer especially through the web. This paper presents a questionnaire to assess student opinion about these tools. To analyze the effectiveness, and make an initial estimate of the evaluation of these tools, we conducted a pilot test of the questionnaire with 68 students at the University of Extremadura. The results of preliminary statistical analysis conducted on the pilot test indicate that the survey results are reliable. A global evaluation of both tools, with a scale of 1 to 5, gave an average score of 3.29 for initial courses and 3.41 for selfevaluation. The 72.9% of the students consider the "self assessment" more effective than the "initial course"

Transmission of digital chaotic and information-bearing signals in optical communication systems

A new proposal to have secure communications in a system is reported. The basis is the use of a synchronized digital chaotic systems, sending the information signal added to an initial chaos. The received signal is analyzed by another chaos generator located at the receiver and, by a logic boolean function of the chaotic and the received signals, the original information is recovered. One of the most important facts of this system is that the bandwidth needed by the system remain the same with and without chaos.

Evaluating alternative industrial network organizations and information systems

Purpose – The purpose of this paper is to present a simulation‐based evaluation method for the comparison of different organizational forms and software support levels in the field of supply chain management (SCM). Design/methodology/approach – Apart from widely known logistic performance indicators, the discrete event simulation model considers explicitly coordination cost as stemming from iterative administration procedures. Findings - The method is applied to an exemplary supply chain configuration considering various parameter settings. Curiously, additional coordination cost does not always result in improved logistic performance. Influence factor variations lead to different organizational recommendations. The results confirm the high importance of (up to now) disregarded dimensions when evaluating SCM concepts and IT tools. Research limitations/implications – The model is based on simplified product and network structures. Future research shall include more complex, real world configurations. Practical implications – The developed method is designed for the identification of improvement potential when SCM software is employed. Coordination schemes based only on ERP systems are valid alternatives in industrial practice because significant investment IT can be avoided. Therefore, the evaluation of these coordination procedures, in particular the cost due to iterations, is of high managerial interest and the method provides a comprehensive tool for strategic IT decision making. Originality/value – Reviewed literature is mostly focused on the benefits of SCM software implementations. However, ERP system based supply chain coordination is still widespread industrial practice but associated coordination cost has not been addressed by researchers.

A language exchange program: sustainability innovation in language and culture engagement

Spanish Educational Laws have been promoting the widespread use of English; as a result, Spanish Uni versities are looking for ways to give students more international training in order to prepare them for a future that will increasingly involve global problems and partnerships. Therefore, the Polytechnic University of Madrid, Spain (UPM), and the University of British Columbia, Okanagan, Canada (UBCO) have come together to offer opportunities for international collaboration and learning, thus facilitating virtual encounters among Spanish and Canadian students. The Language Exchange Program between the UPM and UBCO acts as a model for sustainability innovation in language and culture engagement as the students can interact with native speakers in communication tasks. This interdisciplinary initiative supports the latest methodological principles observed in the Common European Framework for Languages, such as autonomous and life-long learning, self-assessment and peer-assessment as well as the incorporation of new technologies to the learning process. Additionally the ‘virtual’ mobility is provided at no extra cost. This article presents the preliminary results of two virtual exchange programs that have been offering varied forms of study which are venue-independent, and have clearly expanded the range of scenarios for the students on both sides by promoting collaborative work and cultural exchange.

Development of Interactive Materials by Engineering Students Using the Descartes Applets.

In a degree course such as Forestry Engineering, the general teaching objectives consist of explaining and helping students to understand the principles of Mechanics. For some time now we have encountered significant difficulties in teaching this subject due to the students' lack of motivation and to their insufficient prior preparation for the topic. If we add to this the discipline's inherent complexity and the students' preconceptions about the subject, these teaching difficulties become considerable. For this reason a series of didactic activities have been introduced sequentially in the teaching of this subject. This work describes the methodology, procedure and results for the action of developing a work project in groups using Descartes software. The results of this experiment can be considered very positive. Some of the critical preconceptions for learning the subject can be corrected, and the tutoring process in the classroom contributes to an improvement in teacherstudent communication. Since this scheme was established, the number of students taking part each academic year has increased, and this is the group with the greatest percentage of passing scores.

Herramienta basada en vistas para la generación automática de anotaciones de fuentes RDF

Durante los últimos años, el imparable crecimiento de fuentes de datos biomédicas, propiciado por el desarrollo de técnicas de generación de datos masivos (principalmente en el campo de la genómica) y la expansión de tecnologías para la comunicación y compartición de información ha propiciado que la investigación biomédica haya pasado a basarse de forma casi exclusiva en el análisis distribuido de información y en la búsqueda de relaciones entre diferentes fuentes de datos. Esto resulta una tarea compleja debido a la heterogeneidad entre las fuentes de datos empleadas (ya sea por el uso de diferentes formatos, tecnologías, o modelizaciones de dominios). Existen trabajos que tienen como objetivo la homogeneización de estas con el fin de conseguir que la información se muestre de forma integrada, como si fuera una única base de datos. Sin embargo no existe ningún trabajo que automatice de forma completa este proceso de integración semántica. Existen dos enfoques principales para dar solución al problema de integración de fuentes heterogéneas de datos: Centralizado y Distribuido. Ambos enfoques requieren de una traducción de datos de un modelo a otro. Para realizar esta tarea se emplean formalizaciones de las relaciones semánticas entre los modelos subyacentes y el modelo central. Estas formalizaciones se denominan comúnmente anotaciones. Las anotaciones de bases de datos, en el contexto de la integración semántica de la información, consisten en definir relaciones entre términos de igual significado, para posibilitar la traducción automática de la información. Dependiendo del problema en el que se esté trabajando, estas relaciones serán entre conceptos individuales o entre conjuntos enteros de conceptos (vistas). El trabajo aquí expuesto se centra en estas últimas. El proyecto europeo p-medicine (FP7-ICT-2009-270089) se basa en el enfoque centralizado y hace uso de anotaciones basadas en vistas y cuyas bases de datos están modeladas en RDF. Los datos extraídos de las diferentes fuentes son traducidos e integrados en un Data Warehouse. Dentro de la plataforma de p-medicine, el Grupo de Informática Biomédica (GIB) de la Universidad Politécnica de Madrid, en el cuál realicé mi trabajo, proporciona una herramienta para la generación de las necesarias anotaciones de las bases de datos RDF. Esta herramienta, denominada Ontology Annotator ofrece la posibilidad de generar de manera manual anotaciones basadas en vistas. Sin embargo, aunque esta herramienta muestra las fuentes de datos a anotar de manera gráfica, la gran mayoría de usuarios encuentran difícil el manejo de la herramienta , y pierden demasiado tiempo en el proceso de anotación. Es por ello que surge la necesidad de desarrollar una herramienta más avanzada, que sea capaz de asistir al usuario en el proceso de anotar bases de datos en p-medicine. El objetivo es automatizar los procesos más complejos de la anotación y presentar de forma natural y entendible la información relativa a las anotaciones de bases de datos RDF. Esta herramienta ha sido denominada Ontology Annotator Assistant, y el trabajo aquí expuesto describe el proceso de diseño y desarrollo, así como algunos algoritmos innovadores que han sido creados por el autor del trabajo para su correcto funcionamiento. Esta herramienta ofrece funcionalidades no existentes previamente en ninguna otra herramienta del área de la anotación automática e integración semántica de bases de datos. ---ABSTRACT---Over the last years, the unstoppable growth of biomedical data sources, mainly thanks to the development of massive data generation techniques (specially in the genomics field) and the rise of the communication and information sharing technologies, lead to the fact that biomedical research has come to rely almost exclusively on the analysis of distributed information and in finding relationships between different data sources. This is a complex task due to the heterogeneity of the sources used (either by the use of different formats, technologies or domain modeling). There are some research proyects that aim homogenization of these sources in order to retrieve information in an integrated way, as if it were a single database. However there is still now work to automate completely this process of semantic integration. There are two main approaches with the purpouse of integrating heterogeneous data sources: Centralized and Distributed. Both approches involve making translation from one model to another. To perform this task there is a need of using formalization of the semantic relationships between the underlying models and the main model. These formalizations are also calles annotations. In the context of semantic integration of the information, data base annotations consist on defining relations between concepts or words with the same meaning, so the automatic translation can be performed. Depending on the task, the ralationships can be between individuals or between whole sets of concepts (views). This paper focuses on the latter. The European project p-medicine (FP7-ICT-2009-270089) is based on the centralized approach. It uses view based annotations and RDF modeled databases. The data retireved from different data sources is translated and joined into a Data Warehouse. Within the p-medicine platform, the Biomedical Informatics Group (GIB) of the Polytechnic University of Madrid, in which I worked, provides a software to create annotations for the RDF sources. This tool, called Ontology Annotator, is used to create annotations manually. However, although Ontology Annotator displays the data sources graphically, most of the users find it difficult to use this software, thus they spend too much time to complete the task. For this reason there is a need to develop a more advanced tool, which would be able to help the user in the task of annotating p-medicine databases. The aim is automating the most complex processes of the annotation and display the information clearly and easy understanding. This software is called Ontology Annotater Assistant and this book describes the process of design and development of it. as well as some innovative algorithms that were designed by the author of the work. This tool provides features that no other software in the field of automatic annotation can provide.

Proposal for the Management of temporal and semantic components of Geographic Information

This poster raises the issue of a research work oriented to the storage, retrieval, representation and analysis of dynamic GI, taking into account The ultimate objective is the modelling and representation of the dynamic nature of geographic features, establishing mechanisms to store geometries enriched with a temporal structure (regardless of space) and a set of semantic descriptors detailing and clarifying the nature of the represented features and their temporality. the semantic, the temporal and the spatiotemporal components. We intend to define a set of methods, rules and restrictions for the adequate integration of these components into the primary elements of the GI: theme, location, time [1]. We intend to establish and incorporate three new structures (layers) into the core of data storage by using mark-up languages: a semantictemporal structure, a geosemantic structure, and an incremental spatiotemporal structure. Thus, data would be provided with the capability of pinpointing and expressing their own basic and temporal characteristics, enabling them to interact each other according to their context, and their time and meaning relationships that could be eventually established

Infrastructure and Workflow for the Formal Evaluation of Semantic Search Technologies

This paper describes an infrastructure for the automated evaluation of semantic technologies and, in particular, semantic search technologies. For this purpose, we present an evaluation framework which follows a service-oriented approach for evaluating semantic technologies and uses the Business Process Execution Language (BPEL) to define evaluation workflows that can be executed by process engines. This framework supports a variety of evaluations, from different semantic areas, including search, and is extendible to new evaluations. We show how BPEL addresses this diversity as well as how it is used to solve specific challenges such as heterogeneity, error handling and reuse
