Some Issues on Ontology Integration

The word integration has been used with different meanings in the ontology field. This article aims at clarifying the meaning of the word “integration” and presenting some of the relevant work done in integration. We identify three meanings of ontology “integration”: when building a new ontology reusing (by assembling, extending, specializing or adapting) other ontologies already available; when building an ontology by merging several ontologies into a single one that unifies all of them; when building an application using one or more ontologies. We discuss the different meanings of “integration”, identify the main characteristics of the three different processes and proposethree words to distinguish among those meanings:integration, merge and use

How to Find Suitable Ontologies Using an Ontology-based WWW Broker

Knowledge reuse by means of outologies now faces three important problems: (1) there are no standardized identifying features that characterize ontologies from the user point of view; (2) there are no web sites using the same logical organization, presenting relevant information about ontologies; and (3) the search for appropriate ontologies is hard, time-consuming and usually fruitless. To solve the above problems, we present: (1) a living set of features that allow us to characterize ontologies from the user point of view and have the same logical organization; (2) a living domain ontology about ontologies (called ReferenceOntology) that gathers, describes and has links to existing ontologies; and (3) (ONTO)2Agent, the ontology-based www broker about ontologies that uses the Reference Ontology as a source of its knowledge and retrieves descriptions of ontologies that satisfy a given set of constraints. (ONTO)~Agent is available at http://delicias.dia.fi.upm.es/REFERENCE ONTOLOGY

Modeling a complex production line using virtual cells

This chapter presents modeling and simulation of a complex multistage multiproduct production line with four closed loop networks configuration, which also act as a virtual cell. This allows for a greater understanding of the functions within the production line through the simplification of the production flow with the addition of buffers between the cells. Virtual cells are crucial in this instance due to the dynamic configuration, which could help production system designers in optimizing the complex configuration of production

Radio wave attenuation measurement system based on RSSI for precision agriculture: application to tomato greenhouses

Precision agriculture and smart farming are concepts that are acquiring an important boom due to their relationship with the Internet of Things (IoT), especially in the search for new mechanisms and procedures that allow for sustainable and efficient agriculture to meet future demand from an increasing population. Both concepts require the deployment of sensor networks that monitor agricultural variables for the integration of spatial and temporal agricultural data. This paper presents a system that has been developed to measure the attenuation of radio waves in the 2.4 GHz free band (ISM- Industrial, Scientific and Medical) when propagating inside a tomato greenhouse based on the received signal strength indicator (RSSI), and a procedure for using the system to measure RSSI at different distances and heights. The system is based on Zolertia Re-Mote nodes with the Contiki operating system and a Raspberry Pi to record the data obtained. The receiver node records the RSSI at different locations in the greenhouse with the transmitter node and at different heights. In addition, a study of the radio wave attenuation was measured in a tomato greenhouse, and we publish the corresponding obtained dataset in order to share with the research community

Juegos Arcade online sobre mapas reales

Este proyecto implementa juegos arcade, que se desarrollan sobre mapas reales. Están hechos para poder jugar de forma online, a través de internet. La información geográfica necesaria es obtenida de la página de la fundación OpenStreetMap. Es una fundación para crear mapas libre y editables, que cuenta con la colaboración desinteresada de los usuarios de la red. Tenemos dos opciones para elegir el lugar donde se expondrá el juego. Las opciones son: bien jugar sobre unos mapas descargados previamente al realizar la aplicación por los desarroladores, o bien de forma online elegir el lugar sobre el cual queremos jugar. Para esto último nos apoyamos en aplicaciones ofertadas por esta Comunidad como puede ser el namefinder. Nuestra aplicación ha sido desarrollada bajo el lenguaje de programación Java de la empresa Sun Microsystems. Se ha usado como entorno de programación Netbeans, de la misma empresa citada con anterioridad. El proyecto se divide en dos, siguiendo la arquitectura cliente-servidor. El servidor se encarga de toda la computación y el cliente es una página web para poder jugar sobre ella. Para llevar a cabo el cliente se ha usado un applet de Java, que no es más que un programa incrustado en un documento HTML. La conexión entre las dos partes del proyecto citadas se ha realizado a través de sockets. Se ha seguido un protocolo creado por nosotros para que las comunicaciones sean correctas. Los juegos arcades disponibles en la aplicación son: el comecocos, el pilla pilla, la serpiente y el pincha globos. [ABSTRACT] This project implements arcade games, which are developed on real maps. They are made for playing online, over network. The geographic information required is got from OpenStreetMap foundation´s web page. This foundation creates free geographic data, with the unselfish collaboration of network users. We have two options for choosing the place where we will play. The options are either to play on maps downloaded by the developers previously or to choose the place when you are using this application. For the latter we use applications offered by OpenStreetMap, for example namefinder. Our application has been developed under the Java programming language of Sun Microsystems. The programming environment used has been Netbeans, of the same company previously mentioned. This project is divided into two parts, carrying on the client-server architecture. The server does all computation meanwhile and the client is a web page for playing on it. A Java applet has been used for implementing the client, which is a program incrusted in a HTML document. The connection between the two parts of the project is made using sockets. The application use a protocol defined by us for correct communications. The arcade games available in the application are: pacman, the running-running, the snake and click-balloons

Lipid peroxidation: Production, metabolism, and signaling mechanisms of malondialdehyde and 4-hydroxy-2-nonenal

Lipid peroxidation can be described generally as a process under which oxidants such as free radicals attack lipids containing carbon-carbon double bond(s), especially polyunsaturated fatty acids (PUFAs). Over the last four decades, an extensive body of literature regarding lipid peroxidation has shown its important role in cell biology and human health. Since the early 1970s, the total published research articles on the topic of lipid peroxidation was 98 (1970–1974) and has been increasing at almost 135-fold, by up to 13165 in last 4 years (2010–2013). New discoveries about the involvement in cellular physiology and pathology, as well as the control of lipid peroxidation, continue to emerge every day. Given the enormity of this field, this review focuses on biochemical concepts of lipid peroxidation, production, metabolism, and signaling mechanisms of two main omega-6 fatty acids lipid peroxidation products: malondialdehyde (MDA) and, in particular, 4-hydroxy-2-nonenal (4-HNE), summarizing not only its physiological and protective function as signaling molecule stimulating gene expression and cell survival, but also its cytotoxic role inhibiting gene expression and promoting cell death. Finally, overviews of in vivo mammalian model systems used to study the lipid peroxidation process, and common pathological processes linked to MDA and 4-HNE are show
