Interpolation sets in spaces of continuous metric-valued functions

Let $X$ and $M$ be a topological space and metric space, respectively. If $C(X,M)$ denotes the set of all continuous functions from X to M, we say that a subset $Y$ of $X$ is an \emph{$M$-interpolation set} if given any function $g\in M^Y$ with relatively compact range in $M$, there exists a map $f\in C(X,M)$ such that $f_{|Y}=g$. In this paper, motivated by a result of Bourgain in \cite{Bourgain1977}, we introduce a property, stronger than the mere \emph{non equicontinuity} of a family of continuous functions, that isolates a crucial fact for the existence of interpolation sets in fairly general settings. As a consequence, we establish the existence of $I_0$ sets in every nonprecompact subset of a abelian locally $k_{\omega}$-groups. This implies that abelian locally $k_{\omega}$-groups strongly respects compactness

Novel tuneable filter based on MZ and an amplified ring resonator for OFDM networks

IEEE Lasers and Electro-Optics Society. 1999 Annual Meeting. 8-11 November 1999. San Francisco, CAA novel reconfigurable fibre based tuneable filter is proposed. The module relies on a cascaded connection of Mach-Zehnders and an amplified fibre ring resonator. MHz range adjustable FHWM bandwidths and high crosstalk are achieved.Publicad

Internet of Things and Their Coming Perspectives: A Real Options Approach

Internet of things is developing at a dizzying rate, and companies are forced to implement it in order to maintain their operational efficiency. The high flexibility inherent to these technologies makes it necessary to apply an appropriate measure, which properly assesses risks and rewards. Real options methodology is available as a tool which fits the conditions, both economic and strategic, under which investment in internet of things technologies is developed. The contribution of this paper is twofold. On the one hand, it offers an adequate tool to assess the strategic value of investment in internet of things technologies. On the other hand, it tries to raise awareness among managers of internet of things technologies because of their potential to contribute to economic and social progress. The results of the research described in this paper highlight the importance of taking action as quickly as possible if companies want to obtain the best possible performance. In order to enhance the understanding of internet of things technologies investment, this paper provides a methodology to assess the implementation of internet of things technologies by using the real options approach; in particular, the option to expand has been proposed for use in the decision-making process

An ultra low-power hardware accelerator for automatic speech recognition

Automatic Speech Recognition (ASR) is becoming increasingly ubiquitous, especially in the mobile segment. Fast and accurate ASR comes at a high energy cost which is not affordable for the tiny power budget of mobile devices. Hardware acceleration can reduce power consumption of ASR systems, while delivering high-performance. In this paper, we present an accelerator for large-vocabulary, speaker-independent, continuous speech recognition. It focuses on the Viterbi search algorithm, that represents the main bottleneck in an ASR system. The proposed design includes innovative techniques to improve the memory subsystem, since memory is identified as the main bottleneck for performance and power in the design of these accelerators. We propose a prefetching scheme tailored to the needs of an ASR system that hides main memory latency for a large fraction of the memory accesses with a negligible impact on area. In addition, we introduce a novel bandwidth saving technique that removes 20% of the off-chip memory accesses issued during the Viterbi search. The proposed design outperforms software implementations running on the CPU by orders of magnitude and achieves 1.7x speedup over a highly optimized CUDA implementation running on a high-end Geforce GTX 980 GPU, while reducing by two orders of magnitude (287x) the energy required to convert the speech into text.Peer ReviewedPostprint (author's final draft

Natación (1915). Santiago Mestres Fossas

Este artículo resume el libro de Santiago Mestres Fossas titulado "Natación", escrito en 1915, apenas ocho años después del comienzo de la historia de la natación en España. Con este texto el autor no pretende enseñar a nadar, sino servir como soporte teórico y metodológico a aquellos que quieran acompañar a los que no saben nadar y a los nadadores más experimentados en su camino de aprendizaje y perfeccionamiento. Las cualidades esenciales de la natación, los estilos, los concursos, los juegos en el agua y una introducción al salvamento acuático son los temas que aborda el autor en este libro pionero en la natación española.This article is a review of Santiago Mestres Fossas' book intitled "Natación" , published in1915, just eigth years after the beginning of Spanish swimming History. The book was notoriented to teach those who do not swim, but to support their teachers, as well as the proficience swimmers. The main focuses are: essential swimming qualities, stiles, competitions, water games and introduction to lifesaving

Nuevos museos para la enseñanza del patrimonio cultural. El “museo vivo” de Historia del Arte

Este texto, a partir de la revisión de nuevas prácticas existentes en los museos en la actualidad, presenta un proyecto educativo innovador que parte del Departamento de Didácticas Específicas de la Universidad Autónoma de Madrid: “Museo Vivo de Historia del Arte”, que pretende ser, en el ámbito universitario, una herramienta útil para la enseñanza y aprendizaje de esta disciplina y de la Ciencias Sociales. Se basa en la creación de una colección de objetos contemporáneos y cotidianos indicativos de que el patrimonio está al alcance de nuestra mano. En este caso, en torno a la moneda y su capacidad de generar puntos de encuentro entre las matemáticas, el arte y las ciencias socialesUpon reviewing currently new practices in museums, this paper presents an innovative educational project that comes from the Specific Didactics Department from Universidad Autónoma de Madrid: Living Museum of Art History, which claims to be a useful tool for teaching and learning this subject and social sciences in the academic field. It is based on the creation of an everyday objects collection, which indicates that the heritage is at our fingertips. In this case, around the coin and its capacity to create meeting points among mathematics, art and social science
