    Artículo sobre detección de caídas con redes neuronales profundasOwing to the effects of falls on quality of life of the elderly, automatic fall detection systems (FDS) have become a key research topic in the ambit of telecare. This works assesses the performance of convolutional neural networks when they are applied to identify fall accidents in a wearable FDS provided with a tri-axial accelerometer. The evaluation of the detection algorithm is carried out by employing a benchmarking repository with a wide set of traces captured from a wide group of volunteers that executed a programmed series of Activities of the Daily Living (ADLs) and emulated falls. Results show that the CNN can properly distinguish both types of movements with a success rate (specificity and sensitivity) around 99%.Universidad de Málaga.

    A benchmark suite for evaluating the performance of the WebODE Ontology Engineering Platform

    Ontology tools play a key role in the development and maintenance of the Semantic Web. Hence, we need in one hand to objectively evaluate these tools, in order to analyse whether they can deal with actual and future requirements, and in the other hand to develop benchmark suites for performing these evaluations. In this paper, we describe the method we have followed to design and implement a benchmark suite for evaluating the performance of the WebODE ontology engineering workbench, along with the conclusions obtained after using this benchmark suite for evaluating WebODE

    SEALS: Semantic Evaluation At Large Scale

    Recently, the Semantic Web community has seen an explosion of semantic technologies coming not only from research institutions but also from small and large companies. This explosion raises diculties for early adopters since, with a move from research to industry, semantic technologies must meet new require ments that may have not been considered before and existing requirements may become stricter

    Perspectives in Semantic Interoperability

    This paper describes the problem of semantic technology interoperability from two different perspectives. First, from a theoretical perspective by presenting an overview of the different factors that affect interoperability and, second, from a practical perspective by reusing evaluation methods and applying them to six current semantic technologies in order to assess their interoperability

    Interoperability results for Semantic Web technologies using OWL as the interchange language

    Using Semantic Web technologies in complex scenarios requires that such technologies correctly interoperate by interchanging ontologies using the RDF(S) and OWL languages. This interoperability is not straightforward because of the high heterogeneity in Semantic Web technologies and, while the number of such technologies grows, affordable mechanisms for evaluating Semantic Web technology interoperability are needed to comprehend the current and future interoperability of Semantic Web technologies. This paper presents the OWL Interoperability Benchmarking, an international benchmarking activity that involved the evaluation of the interoperability of different Semantic Web technologies using OWL as the interchange language. It describes the evaluation resources used in this benchmarking activity, the OWL Lite Import Benchmark Suite and the IBSE tool, and presents how to use them for evaluating the OWL interoperability of Semantic Web technologies. Moreover, the paper offers an overview of the OWL interoperability results of the eight tools participating in the benchmarking: one ontology-based annotation tool (GATE), three ontology frameworks (Jena, KAON2, and SWI-Prolog), and four ontology development tools (Protégé Frames, Protégé OWL, SemTalk, and WebODE)

    The Semantic Web technology needs to be thoroughly evaluated for providing objective results and obtaining massive improvement in its quality; thus, the transfer of this technology from research to industry will speed up. This chapter presents software benchmarking, a process that aims to improve the Semantic Web technology and to find the best practices. The chapter also describes a specific software benchmarking methodology and shows how this methodology has been used to benchmark the interoperability of ontology development tools, employing RDF(S) as the interchange language

    Diseño y acondicionamiento acústico y electroacústico de una sala de proyecciones en 3D

    Full text link
    Este proyecto está orientado al diseño y el acondicionamiento de una sala de cine siguiendo las normas establecidas por el SMPTE. El primer paso a realizar será el diseño de la sala en el cual habrá que tener en cuenta la distribución de los asientos dentro de la misma, el dimensionado de la pantalla que servirá para establecer la forma y dimensiones del recinto, así como la correcta ubicación del proyector. Posteriormente se realizará el acondicionamiento acústico del cine, con la elección de los diferentes materiales que permitan la obtención de un tiempo de reverberación óptimo. A continuación se procederá a la selección de los equipos electroacústicos más adecuados y a su colocación a lo largo de la sala para posteriormente realizar un estudio de todos los parámetros de esta para garantizar la perfecta escucha dentro de la misma. Se elegirán, al igual que se ha hecho con los elementos electroacústicos, los equipos de video específicos, teniendo en cuenta el sistema de proyección 3D utilizado y se procederá a su instalación dentro de la sala. Se indicará de forma independiente cual será el esquema de conexionado correspondiente a cada una de las partes, tanto de audio como de video. Todos los equipos y parámetros ajustables de la sala, tanto de audio como de video, se realizaran siguiendo las recomendaciones establecidas por el SMPTE para una correcta visión y escucha, así como también el diseño de la sala. Para llevar a cabo todo lo anteriormente descrito se utilizara el programa de simulación EASE 4.3 con él que se ajustaran los parámetros más significativos para verificar que la sala cumple con las condiciones de escucha que determina la norma. Todo esto irá acompañado de un presupuesto detallado de cada uno de los equipos y materiales utilizados, así como de los costes derivados de la mano de obra. Se adjuntarán también los planos de la sala donde se indicarán todas las medidas establecidas a lo largo del proyecto. Para la realización de estos se utilizara el programa de diseño Google SkechUp. Por último se facilitarán las hojas de características de cada uno de los equipos instalados en la sala para conocer sus especificaciones y modo de funcionamiento. Abstract This project is orientated at designing and conditioning a cinema according to standards set by the SMPTE. First of all, the cinema hall needs to be designed, taking into consideration seat distribution and screen dimension, in order to establish the shape and dimensions of the room and the correct location for the projector. Later the acoustic conditioning of the cinema is covered, with the choice of appropriate materials in order to permit an optimum reverberation time. The next step is the selection of the most appropriate electro-acoustic equipment and its positioning throughout the room. A study is then carried out of all the parameters to ensure perfect hearing in the cinema. Then the specific video equipment is chosen, bearing in mind the 3D projection system used and is installed in the theatre. A wiring diagram is indicated for each element used, for both audio and video. All equipment and adjustable parameters of the room, both audio and video, are made according to the recommendations established by the SMPTE for correct viewing and listening, as is the design of the cinema. To carry out the steps described above the EASE 4.3 simulation program is used. This program adjusts all significant parameters to verify that the room complies with the listening conditions determined by the standard. A detailed budget is included for all equipment and materials used, as well as the labour costs. Plans of the room, showing all measurements taken during the project are indicated. This is done using the Google SkechUp program. Finally data sheets are provided for each piece of equipment installed in the room detailing specifications and operating mode
