Desarrollo de móvil teledirigido basado en ROS

EN los últimos años ha habido una creciente tendencia hacia el desarrollo de nuevas tecnologías que le permitan al usuario extender su experiencia y ampliar su percepción del entorno, haciendo de esto algo más cercano a la realidad de lo que era posible hace tan solo un par de décadas. El objetivo de este trabajo es crear una plataforma móvil teledirigida basada en el sistema operativo para robots ROS (Robot Operating System), que puede definirse como un mecanismo provisto de un sistema de automoción diferencial para desplazarse en entornos predeterminados y operado desde la distancia, la que a su vez ha sido pensada para el monitoreo de espacios. La realización del estudio se justifica por la necesidad de buscar una respuesta a £por qué teleoperar un robot móvil? Lo que ha resultado ser al hecho de que el usuario necesita ampliar su percepción del entorno cuando no le es posible ingresar a él, ya sea por sus dimensiones físicas (en derrumbes), que su integridad esté comprometida (al manipular o neutralizar explosivos), el desconocimiento de lo que podría enfrentar (en desastres naturales), o tan solo porque es más práctico en términos económicos, físicos o de tiempo (en la vigilancia de espacios). Este artículo se estructura en los siguientes apartados: el primer lugar un panorama general de la tecnología empleada. En segunda instancia la descripción del hardware y del software que componen la plataforma móvil teledirigida. A continuación, da cuenta del proceso de instalación y configuración hasta la puesta en marcha. Finalmente, se presentan las conclusiones y algunas proyecciones para futuros desarrollos, seguido de la bibliografía del trabajo.
Análisis y detección temprana de deserción estudiantil en UTN FRLP

RESUMEN La deserción es entendida como aquella situación a la que se enfrenta un estudiante cuando aspira y no logra concluir su proyecto educativo. Esto constituye una de las problemáticas de mayor preocupación en el sistema universitario, debido al aumento de su ocurrencia en los últimos años. En Argentina, se estima que en las universidades nacionales sólo el 12% de los estudiantes que ingresan se gradúa y si bien no hay datos oficiales para las instituciones privadas, se estima que un 30% concluye con éxito su carrera. Por este motivo, se plantea el diseño y desarrollo de un sistema informático para la detección y caracterización temprana de posibles desertores, como una propuesta metodológica que brinde un modelo explicativo de los principales factores causales de la deserción y su impacto en la institución. Asimismo se espera que este sistema sirva a tutores, docentes, equipo interdisciplinario y autoridades académicas como fundamento a partir del cual generar estrategias de intervención.
Video quality prediction for video over wireless access networks (UMTS and WLAN)

Transmission of video content over wireless access networks (in particular, Wireless Local Area Networks (WLAN) and Third Generation Universal Mobile Telecommunication System (3G UMTS)) is growing exponentially and gaining popularity, and is predicted to expose new revenue streams for mobile network operators. However, the success of these video applications over wireless access networks very much depend on meeting the user’s Quality of Service (QoS) requirements. Thus, it is highly desirable to be able to predict and, if appropriate, to control video quality to meet user’s QoS requirements. Video quality is affected by distortions caused by the encoder and the wireless access network. The impact of these distortions is content dependent, but this feature has not been widely used in existing video quality prediction models. The main aim of the project is the development of novel and efficient models for video quality prediction in a non-intrusive way for low bitrate and resolution videos and to demonstrate their application in QoS-driven adaptation schemes for mobile video streaming applications. This led to five main contributions of the thesis as follows: (1) A thorough understanding of the relationships between video quality, wireless access network (UMTS and WLAN) parameters (e.g. packet/block loss, mean burst length and link bandwidth), encoder parameters (e.g. sender bitrate, frame rate) and content
Issue Reorganization Using the Measure of Relevance

The need to extract R&D keywords from issues and use them to retrieve R&D information is increasing rapidly. However, it is difficult to identify related issues or distinguish them. Although the similarity between issues cannot be identified, with an R&D lexicon, issues that always share the same R&D keywords can be determined. In detail, the R&D keywords that are associated with a particular issue imply the key technology elements that are needed to solve a particular issue. Furthermore, the relationship among issues that share the same R&D keywords can be shown in a more systematic way by clustering them according to keywords. Thus, sharing R&D results and reusing R&D technology can be facilitated. Indirectly, redundant investment in R&D can be reduced as the relevant R&D information can be shared among corresponding issues and the reusability of related R&D can be improved. Therefore, a methodology to cluster issues from the perspective of common R&D keywords is proposed to satisfy these demands. Keywords—Clustering, Social Network Analysis, Text Mining, Topic Analysis.
Simulation of quality of service mechanisms in the UMTS terrestrial radio access network

Supporting multiple traffic classes with different QoS (quality of service) constraints in third generation mobile systems is not a straightforward problem. This issue becomes critical at the access network interfaces, where transmission resources are usually expensive. One of the most important interfaces is the one that connects each base station with its controller, because there can be many instances of it. We have approached the dimensioning of this interface from the perspective of simulation, concretely for the UMTS (Universal Mobile Telecommunications System) access network. We have developed a simulation model capable of representing multi-service scenarios inside this particular UTMS interface. This tool can be fed with traffic of different types, representing the different traffic classes defined for UMTS, and is able to simulate traffic differentiation both at the ATM (Asynchronous Transfer Mode) and the AAL2 (ATM Adaptation Layer 2) level. We present simulation results showing how the simulator can aid us in the task of access network dimensioning with QoS constraints.
Nutrition in Prevention and Treatment of Alzheimer’s and Parkinson’s Diseases

The process of aging concerns every single person and is impossible to contain. This is a physiological process and can lead to many various diseases, including neurodegenerative ones. The European society is aging. It is estimated that in 2050, 30% of the European population will be over 65. In an aging society, geriatric diseases, such as Alzheimer’s and Parkinson’s diseases, pose an increasingly serious medical, social and economic problems. We are still looking for new methods of preventing and treating such diseases. However, it is possible to support the treatment with an appropriate diet. The ongoing research indicates a beneficial influence of such substances as mono and polyunsaturated fats (especially docosahexaenoic acid), antioxidant vitamins (vitamin C and E), glutathione, coenzyme Q10, turmeric, flavonoids and caffeine on the prevention and treatment of neurodegenerative diseases. The current study presents the results of the research of diets of patients with Alzheimer’s and Parkinson’s diseases and gives relevant recommendations (Piel. Zdr. Publ. 2015, 5, 2, 199–208).
Categorization of Sound Attributes for Audio Quality Assessment — A Lexical Study

For the evaluation of perceived quality in audio coding, two well-known subjective test methods, both of which are based on Basic Audio Quality (BAQ), are recommended by the International Telecommunication Union. Although a predictor of quality, BAQ is likely to be multidimensional. Listening tests can be used to evaluate other attributes that contribute to impairments created by coding. The goal of this study is to define categories of additional attributes, thereby providing a complement to the single BAQ metric. When quality attributes are sorted, there appears to be three groups: one related to space, a second related to defects, and a third split into timbre and quality.
First Person: New Media As Story, Performance, And Game

Electronic games have established a huge international market, significantly outselling non-digital games; people spend more money on The Sims than on "Monopoly" or even on "Magic: the Gathering. " Yet it is widely believed that the market for electronic literature -- predicted by some to be the future of the written word -- languishes. Even bestselling author Stephen King achieved disappointing results with his online publication of "Riding the Bullet" and "The Plant. " Isn't it possible, though, that many hugely successful computer games -- those that depend on or at least utilize storytelling conventions of narrative, character, and theme -- can be seen as examples of electronic literature? And isn't it likely that the truly significant new forms of electronic literature will prove to be (like games) so deeply interactive and procedural that it would be impossible to present them as paper-like "e-books"? The editors of First Person have gathered a remarkably diverse group of new media theorists and practitioners to consider the relationship between "story" and "game," as well as the new kinds of artistic creation (literary, performative, playful) that have become possible in the digital environment. This landmark collection is organized as a series of discussions among creators and theorists; each section includes three presentations, with each presentation followed by two responses. Topics considered range from "Cyberdrama" to "Ludology" (the study of games), to "The Pixel/The Line" to "Beyond Chat. " The conversational structure inspired contributors to revise, update, and expand their presentations as they prepared them for the book, and the panel discussions have overflowed into a First Person web site (created in conjunction with the online journal Electronic Book Review).
Effect of hormonal and non-hormonal treatment on reproductive efficiency and plasma progesterone, biochemical and macrominerals profile in postpartum anoestrus buffaloes.

Fifty two postpartum anoestrus Surti buffaloes selected through glynaeco-clinical examinations in three village co-operative societies of Panchmahal district were randomly divided into four groups. Group-A (n=14) was treated with oral supplementation of Chelated mineral mixture @ 30 g/day/animal for one month, Group-B (n=14) with Inj. inorganic phosphorus and Inj. vitamin AD3E 10 ml each, im at weekly interval for three consecutive week, Group-C (n=12) with Inj. GnRH (Receptal) 5.0 ml, im once and Group-D (n=12) served as untreated control. The effect of above treatments on reproductive efficiency and plasma profile of progesterone and various biochemical and macrominerals was studied at pre-treatment, at induced oestrus and 22nd day post-AI. Significantly higher oestrus induction response (83.33%), the highest conception rate (80.00%) and reproductive efficiency (66.66%) were observed for group-C GnRH treated buffaloes followed by group-B and A, and the values were lowest in control group-D. The mean plasma progesterone (ng/ml) levels were significantly (P<0.05) higher at day 22nd post-AI in all the groups compared to those at pretreatment and induced oestrus phase. The mean plasma protein level was significantly (P<0.05) higher at induced oestrus and 22nd day post-AI than at pre-treatment level in group-A (7.25 ± 0.22 and 7.31 ± 0.18 Vs 6.52 ± 0.31 g/dl). The mean total cholesterol levels (mg/dl) were non-significantly higher at induced oestrus and 22nd day post-AI than at pre-treatment level in all the groups. Plasma calcium levels were significantly (P<0.05) higher at induced oestrus and 22nd day post-AI than that at pretreatment level in group-B. Similarly the mean plasma inorganic phosphorus level was significantly higher at induced oestrus than the pre-treatment level in group-A. The mean plasma calcium and inorganic phosphorus levels at different stages showed non-significant differences in buffaloes of other groups. Results showed that, injection of GnRH had beneficial effect on reproductive performance of postpartum anoestrus buffaloes as compared to vitamin-mineral supplementation.
Abstract 21342: Angiotensin II Blockade and Beta-Blockade Combination Therapy Slows Down the Aortic Root Dilatation in Patients with Marfan Syndrome

Introduction: Beta-blockade, the standard treatment for Marfan syndrome (MFS), had limited effects in aortic root growth. Losartan, an angiotensin II blockade (ARB), had potential efficacy to prevent aortic root dilatation in an animal model of MFS. Hypotheses. Combination therapy with ARB and beta-blockade has synergic effects on attenuation of aortic root dilation in patients with MFS. Methods: A randomized, open-label, active control trial was conducted in National Taiwan University Hospital. From May 2007 to Jan 2010, twenty-eight patients (M/F: 12/16, 16.5 ± 6.6 years) diagnosed as MFS with recognized aortic root dilation (Z score >2.0) and under beta-blockade were enrolled and randomized into two groups. One group continued previous beta-blocker therapy. The other group received a combination therapy with beta-blocker and ARB. The study medication, Losartan, was prescribed with a starting dose and then titrated to an optimal dose in one to two weeks according to the resting heart rate and blood pres.

The underlying theory is summarized and simulation results are presented to show that one power-electronic converter operated in the current-source mode can be used to provide sufficient data to estimate all the parameters of the model, including the mutual coupling inductances between the rotor circuit and the two stator circuits. Laboratory results are presented, along with the constraints imposed in the measurement process. <<ETX>>
Fenotipos de sibilância em idade pré-escolar. Factores de risco para persistência, orientações para o diagnóstico e utilidade clínica

A asma e a sibilância recorrente, nas suas diferentes expressoes fenotipicas, estao entre as patologias mais comuns em idade escolar, mas tambem entre as mais dificeis de abordar pela escassez de sintomatologia, que pode traduzir diferentes diagnosticos e sobretudo diferentes prognosticos. Nas ultimas decadas assistiu- se a uma grande evolucao do conhecimento, resultado em grande parte de estudos longitudinais, como o de Tucson, que permitiram a separacao de diferentes fenotipos de sibilância e a melhor compreensao dos diversos factores envolvidos: geneticos, ambientais e de desenvolvimento pulmonar e das vias aereas. Apesar da melhor caracterizacao fenotipica, a abordagem diagnostica e terapeutica da sibilância em idade pre-escolar mantem-se dificil, sobretudo na aplicacao individual do conhecimento. Trata-se duma entidade heterogenea, cujo prognostico a longo prazo varia desde a recuperacao total, na maior parte dos casos, ate ao diagnostico de asma ou perturbacao irreversivel da funcao pulmonar. Neste artigo reveem-se a epidemiologia da sibilância em idade pre-escolar, os fenotipos mais frequentemente utilizados e factores de risco, e enuncia-se a problematica da abordagem diagnostica no doente individual. Neste grupo etario, a sibilância recorrente ou persistente associada a atopia e com evolucao para asma e a sibilância precoce, transitoria associada a infeccoes virais, sao as formas mais frequentes de apresentacao e esta e a classificacao fenotipica que parece emergir com maior relevância na orientacao terapeutica e prognostica.

Analysis of Protein–RNA Interactions with Single‐Nucleotide Resolution Using iCLIP and Next‐Generation Sequencing

Post-transcriptional regulation of gene expression is controlled by the unique composition and spatial arrangement of RNA-binding proteins (RBPs) on individual transcripts. Therefore, understanding post-transcriptional regulation requires precise and comprehensive binding site maps for RBPs. UV cross-linking and immunoprecipitation (CLIP) is a state-of-the-art technique for generating such maps on a genome-wide scale. However, data complexity is often limited and the resolution of the resulting maps is confined to approximately 30 nucleotides. This, in turn, complicates the identification of individual binding sites. We recently described individual-nucleotide resolution CLIP (iCLIP) - an approach that both increases data complexity and allows binding site detection at single-nucleotide resolution. Here, we present the latest version of our iCLIP protocol, discussing critical aspects and recent modifications. © 2012 Wiley-VCH Verlag GmbH & Co. KGaA. All rights reserved.

USING EXTERNAL SOURCES TO IMPROVE RESEARCH TALK RECOMMENDATION IN SMALL COMMUNITIES

In academic research communities, a typical way to spread ideas or seek for collaboration is through research talks, which might be presented at departmental colloquia or might be in given at conferences. Given a large number of research talks, with some of them happening in parallel, it becomes increasingly harder to focus on those of that are of most interest. To solve this problem, talk recommendation systems can help academics identify the most useful talks among many. This dissertation investigates methods to improve research talk recommendations, both for conference attendees and for faculty and students at a research university. More specifically, the focus of this thesis is the use of external information about user interests as a way to address the challenges of having limited data about target users. The thesis examines several kinds of external sources such as user home page, bibliography, external bookmarks, and user profiles from external information systems and explores impact of this information on the quality of talk recommendation in a general situation and in a cold-start context. For this study, the dissertation uses data from two existing talk recommendation systems, CoMeT and Conference Navigator 3, and an academic paper search system, SciNet.
