Context awareness is an important issue in ambient intelligence to anticipate the desire of the user and, in consequence, to adapt the system. In context awareness, localization is very important to enable a responsive environment for the users. Focusing on this issue, this paper presents a localization system based on the use of Wireless...

Locating nodes is a fundamental problem in wireless networks with hundreds of devices deployed in a wide area. This is especially relevant for mobile nodes. Wireless sensor nodes are usually powered by small batteries, solar panels or piezoelectric generators, so that, and consequently, power consumption is the main constraint to deal with. But...

The localization of the sensor nodes is a fundamental problem in wireless sensor networks. There are a lot of different kinds of solutions in the literature. Some of them use external devices like GPS, while others use special hardware or implicit parameters in wireless communications. In applications like wildlife localization in a natural...

In a system formed by hundreds of sensors deployed in a huge area it is important to know the position where every sensor is. This information can be obtained using several methods. However, if the number of sensors is high and the deployment is based on ad-hoc manner, some auto-locating techniques must be implemented. In this paper we describe...

Industrial distributed control continues the move toward networks at all levels. At lower levels, control networks provide flexibility, reliability, and low cost, although perhaps the simplest but most important advantage is the reduced volume of wiring. Powered fieldbuses offer particular notable benefits in system wiring simplification....

Currently, wireless sensor networks (WSNs) are formed by devices with limited resources and limited power energy availability. Thanks to their cost effectiveness, flexibility, and ease of deployment, wireless sensor networks have been applied to many scenarios such as industrial, civil, and military applications. For many applications, security...

Determining the importance of different management areas in a company provides guidance about the needs of increasing the analysis and actions focuses in particular topic. To do it, it is necessary to decompose the management in a coherent set of specific management areas and provide a way that allows the company to determine the importance of...

El objetivo ha sido el diseño de un sistema de ayuda a la decisión para la planificación del servicio de recogida de residuos sólidos urbanos de una ciudad. El sistema recoge datos de sensores ubicados en algunos contenedores (volumen) y cada vez que se vacía un contenedor (peso). La principal novedad del sistema consiste en la obtención de un...

Head-related transfer function (HRTF) individualization can improve the perception of binaural sound. The interaural time difference (ITD) of the HRTF is a relevant cue for sound localization, especially in azimuth. Therefore, individualization of the ITD is likely to result in better sound spatial localization. A study of ITD has been...

The failures (known in the terminology of the Airbus DS Company as "incidences") in the test process of an aircraft create delays and costs for the company. Our team from the Electronic Technology Department (Spain) worked with the Airbus DS Company and developed a framework for incidence prediction from a data mining process. Specifically, the...

This paper presents a study of the most suitable ground test equipment for the Airbus A400M aircraft aimed at optimizing a design that combines portability, flexibility, and configurability. The study is based on current trends in the configuration of the different parts that are involved in the process of designing Aircraft Interface Modules...

One hundred development and certification ground tests must be performed before the A400M aircraft's first flight. Ground testing is an essential but also expensive process performed by the Airbus Defense and Space (Airbus DS) Company in the manufacturing cycle of an aircraft. This process involves the repetition of a large group of tests due...

Battery systems are extensively used in smart energy systems in many different applications, such as Frequency Containment Reserve or Self-Consumption Increase. The behavior of a battery in a particular operation scenario is usually summarized using different key performance indicators (KPIs). Some of these indicators such as efficiency...

Método de localización inteligente sobre redes de sensores inalámbricos que comprende un primer proceso distribuido, ejecutado en cada nodo que realiza una estimación de la posible localización del Tag; y un segundo proceso centralizado, que une todas esas informaciones parciales en una única solución.

The best way to obtain relevant information about the behaviour of animals is direct observation (of individuals). However, traditional close-up observations can interfere on the behaviour, and taking biometric measurements requires the capture of individuals, which also causes stress. This paper describes an automatic motoring system for birds...

Este trabajo pretende localizar visualmente la posición de paneles de una instalación termosolar para, en un procesado posterior, detectar y clasificar fallos en los mismos. Estas imágenes se consiguen gracias al vuelo de un dron sobre la planta fotovoltaica, este dron está dotado con una cámara termográfica que tomará las imágenes. Para...

In this paper we present a novel algorithm, implemented in a wireless sensor network environment, for the study of fire in a natural environment. This algorithm can offer two kinds of information: the risk of a fire and, in case of an active fire, the propagation direction of the flames and their velocity. This information is useful for fire...

The study of forest fires has been traditionally considered as an important application due to the inherent danger that this entails. This phenomenon takes place in hostile regions of difficult access and large areas. Introduction of new technologies such as Wireless Sensor Networks (WSNs) has allowed us to monitor such areas. In this paper, an...

En los últimos años estamos asistiendo a un creciente interés a nivel mundial por la conservación y protección de espacios de interés ecológico. La adquisición de datos en entornos naturales protegidos está siempre limitada a acciones que no perturben a los seres vivos del ecosistema; por este motivo, los investigadores deben enfrentarse a dos...

There is a growing demand to equip Smart Water Networks (SWN) with advanced sensing and computation capabilities in order to detect anomalies and apply autonomous event-triggered control. Cyber-Physical Systems (CPSs) have emerged as an important research area capable of intelligently sensing the state of SWN and reacting autonomously in...

This paper shows different issues found in the real implementation of either a WSN or its data exploitation system for an environmental monitoring application. A generic software architecture for interfacing both is proposed and tested on a real case.

Traditionally,Wireless SensorNetworks (WSNs) are used for monitoring an extensive area. In these networks, a centralized server is usually used to collect and store the sensor information.However, new distributed protocols allow connections directly to theWSN nodes without the need of a centralized server.Moreover, these systems are able to...
