Oxidized Forms of Antiaromatic Oligomers of Biphenylene

Rsumen de la comunicaciónThe importance of antiaromatic molecules in Chemistry and more recently in material science is rising. In the particular case of applications in electronics, the antiaromatic skeleton offers the favorable situation of high energy (i.e., destabilized) occupied molecular orbitals allowing to ease oxidation, doping or electron transfer to form conductive and photo-active substrates.Universidad de Málaga.

3D human pose estimation from depth maps using a deep combination of poses

Many real-world applications require the estimation of human body joints for higher-level tasks as, for example, human behaviour understanding. In recent years, depth sensors have become a popular approach to obtain three-dimensional information. The depth maps generated by these sensors provide information that can be employed to disambiguate the poses observed in two-dimensional images. This work addresses the problem of 3D human pose estimation from depth maps employing a Deep Learning approach. We propose a model, named Deep Depth Pose (DDP), which receives a depth map containing a person and a set of predefined 3D prototype poses and returns the 3D position of the body joints of the person. In particular, DDP is defined as a ConvNet that computes the specific weights needed to linearly combine the prototypes for the given input. We have thoroughly evaluated DDP on the challenging 'ITOP' and 'UBC3V' datasets, which respectively depict realistic and synthetic samples, defining a new state-of-the-art on them.Comment: Accepted for publication at "Journal of Visual Communication and Image Representation

Shipbuilding 4.0 Index Approaching Supply Chain

The shipbuilding industry shows a special interest in adapting to the changes proposed by the industry 4.0. This article bets on the development of an index that indicates the current situation considering that supply chain is a key factor in any type of change, and at the same time it serves as a control tool in the implementation of improvements. The proposed indices provide a first definition of the paradigm or paradigms that best fit the supply chain in order to improve its sustainability and a second definition, regarding the key enabling technologies for Industry 4.0. The values obtained put shipbuilding on the road to industry 4.0 while suggesting categorized planning of technologies

Kilo-instruction processors: overcoming the memory wall

Historically, advances in integrated circuit technology have driven improvements in processor microarchitecture and led to todays microprocessors with sophisticated pipelines operating at very high clock frequencies. However, performance improvements achievable by high-frequency microprocessors have become seriously limited by main-memory access latencies because main-memory speeds have improved at a much slower pace than microprocessor speeds. Its crucial to deal with this performance disparity, commonly known as the memory wall, to enable future high-frequency microprocessors to achieve their performance potential. To overcome the memory wall, we propose kilo-instruction processors-superscalar processors that can maintain a thousand or more simultaneous in-flight instructions. Doing so means designing key hardware structures so that the processor can satisfy the high resource requirements without significantly decreasing processor efficiency or increasing energy consumption.Peer ReviewedPostprint (published version

Approach of the naval industry towards industry 4.0

One of the most relevant industrial sectors worldwide is the naval sector, being involved in multiple commercial activities. According to data from UNCTAD (United Nations Conference on Trade and Development) [1], it is important to have a large enough naval fleet to meet maritime needs. This includes the shipbuilding sector, which is responsible for the manufacture and repair of the different types of ships and structures in order to respond to the commercial activities that make up this industry

Monitorización de víctimas con manipuladores aéreos en operaciones de búsqueda y rescate

En este trabajo se presenta el primer dispositivo de monitorización de víctimas para su colocación automática con robots manipuladores aéreos. Se trata de un sistema sensorial distribuido para la evaluación de forma continua del estado de salud de víctimas de catástrofes. Se describen el sensor diseñado y el sistema de comunicaciones, así como la aplicación mediante la colocación del sensor basado en el uso de sistemas aéreos no tripulados (UAS) o robots manipuladores aéreos. El dispositivo de monitorización continua ofrece ventajas sobre el sistema de triage actual ya que permite obtener datos de la evolución de cada víctima. Recoge medidas de las constantes vitales de las víctimas, que son publicadas mediante protocolos de Internet de las Cosas (IoT) que permiten su procesado de forma remota. Además, posee métodos basados en aprendizaje profundo para la detección automática de la posición relativa de la muñeca del brazo de una persona con respecto al manipulador aéreo. Se han realizado experimentos preliminares de obtención de medidas y de colocación de sensores mediante una versión preliminar del sensor, cuyos resultados se incluyenUniversidad de Málaga.

ANÁLISIS DEL DESEMPLEO, LA MIGRACIÓN Y LA POBREZA EN MÉXICO

La mayoría de los movimientos poblacionales en todas las regiones geográficas del mundo, obedecen principalmente a motivaciones vinculadas con la búsqueda de mejores condiciones de vida. No obstante, en casi todos los casos el costo social de lograr que los hogares reciban lo necesario para sobrevivir es la ruptura familiar y la seguridad personal.Los graves problemas que están enfrentando las economías subdesarrolladas con bajo o nulo crecimiento económico, altas tasas de desempleo, elevado índice de migración y millones de habitantes en pobreza extrema. El objetivo del presente trabajo fue analizar el desempleo, la migración y la pobreza en México. El desempleo es uno de los problemas de la economía mexicana (según INEGI de 5.5%), le sigue la migración y la pobreza extrema. Debido al incremento del desempleo y los bajos salarios que tiene el país estimulan a las personas a emigrar. Aunado a lo anterior, en Estados Unidos de América la tasa de desempleo de los migrantes mexicanos se elevó de 8.0% a 12.0% (2009) aproximadamente, provocando una fuerte disminución en las remesas, lo que trae como consecuencia una baja en los ingresos de las familias que viven de dichas transferencias ocasionando que se agudice la pobreza en el país
