Low Profile Multi-Band Antenna for Mobile Communications

In this paper, the design of low profile antennas by using Electromagnetic Band Gap (EBG) structures is introduced. Taking advantage of the fact that they can behave as Perfect Magnetic Conductor (PMC), it is shown that these structures exhibit dual band in-phase reflection at WLAN (Wireless Local Area Network) bands, the 2.4 GHz and 5.2 GHz bands. These structures are applied to PIFA (Planar Inverted-F Antenna) and the results show that it is possible to obtain low profile PIFA's

QoS-based surrogates selection and service proposal formulation in offloading environments

Resource constraints are becoming a problem as many of the wireless mobile devices have increased generality. Our work tries to address this growing demand on resources and performance, by proposing the dynamic selection of neighbor nodes for cooperative service execution. This selection is in uenced by user's quality of service requirements expressed in his request, tailoring provided service to user's speci c needs. In this paper we improve our proposal's formulation algorithm with the ability to trade o time for the quality of the solution. At any given time, a complete solution for service execution exists, and the quality of that solution is expected to improve overtime

IoT for Energy-Efficiency: connecting a serious game with energy metering in the EnerGAware project

The Internet of Things (IoT) emerged with the potential to change our daily lives and the way we interact and operate with our environment. However, in practice, IoT mixes a multitude of devices and subsystems, which are required to work together to provide the user with the expected quality of service. This leads to considerable development challenges, which are exacerbated by the speed of development and heterogeneity of IoT devices. This communication describes an IoT solution being implemented in the setting of a serious game application, connected to real homes energy consumption. The solution follows a publish-subscribe architecture to decouple the components of the system.info:eu-repo/semantics/publishedVersio

The EnerGAware Middleware Platform

IECON 2017, 43rd Annual Conference of the IEEE Industrial Electronics Society (IES). Beijing, China.More and more cyber-physical systems and the internet of things push for a multitude of devices and systems, which need to work together to provide the services as required by the users. Nevertheless, the speed of development and the heterogeneity of devices introduces considerable challenges in the development of such systems. This paper describes a solution being implemented in the setting of a serious game scenario, connected to real homes energy consumption. The solution provides a publish-subscribe middleware which is able to seamlessly connect all the components of the system.info:eu-repo/semantics/publishedVersio

La colaboración del autor en la conservación y restauración del arte contemporáneo: la escultura "A taberna", de Jaime Azinheira

La conservación y restauración del arte contemporáneo presenta desafíos distintos de aquellos del arte antiguo. Las obras de autor vivo tiene el cliente como interlocutor pero la opinión del autor debe también ser considerada en la definición de las varias dimensiones de intervención. El autor o los propietarios de los derechos de autor pueden ser facilitadores del proceso, contribuyendo con información sobre materiales y técnicas, prioridades de preservación o con la colaboración directa en las operaciones de restauración. La escultura A Taberna es una obra de autoria de Jaime Azinheira, creada en 1984 por ocasión de su trabajo final de carrera y forma parte de la colección del Museu de Arte Contemporânea da Bienal de Cerveira, en Portugal. Se compone de varias piezas de yeso y sisal modeladas con espátulas y raspadores, unidas con los mismos materiales y su estructura está hecha con ripias de madera reutilizadas y dispuestas según sus dimensiones interiores. La policromía estaba costituída por pigmentos aglutinados en goma-laca y álcohol etílico. La degradación de los materiales y el estado de conservación en que la obra se encontraba se debían a las inadecuadas condiciones de exposición, transporte y almacenaje a lo largo de 25 años.Tópico 2: Conservación y restauración de pinturas, cueros, textiles y metales

Timing Analysis Methodology

This chapter focuses on the analysis of the timing behavior of software applications that expose real-time (RT) requirements. The state-of-the-art methodologies to timing analysis of software programs are generally split into four categories, referred to as static, measurement-based, hybrid, and probabilistic analysis techniques. First, we present an overview of each of these methodologies and discuss their advantages and disadvantages. Next, we explain the choices made by our proposed methodology in Section 5.2 and present the details of the solution in Section 5.3. Finally, we conclude the chapter in Section 5.4 with a summary.info:eu-repo/semantics/publishedVersio
