Corporate bonds, asset-backed securities and deferred checks in Argentina

We describe the evolution of three types of corporate securities in Argentina, namely, corporate bonds, asset-backed securities and deferred checks. Corporate bonds (obligaciones negociables) were legally authorized in 1988, and after a tax reform in 1991 they became an important financing vehicle. Asset backed securities (fideicomisos), legally created in 1995, have been issued since 1996. They typically bundle together small credits of a similar category. Deferred checks (cheques de pago diferido) exist since 1993, alongside standard checks. They can be negotiated on the exchange since 2003, and are akin to commercial paper. Corporate bonds have been overwhelmingly issued by large firms and banks, with an average issue size of 53 million dollars. Asset backed securities have an average value of 9 million dollars. Deferred checks are typically used by smaller firms, and those traded on the exchange of the Buenos Aires board of trade have an average value of 9 thousand dollars.private securities, corporate bonds, asset-backed securities, deferred checks

Silhouette-based human action recognition with a multi-class support vector machine

This paper has been presented at : 9th International Conference on Pattern Recognition Systems (ICPRS 2018)Computer vision systems have become increasingly popular, being used to solve a wide range of problems. In this paper, a computer vision algorithm with a support vector machine (SVM) classifier is presented. The work focuses on the recognition of human actions through computer vision, using a multi-camera dataset of human actions called MuHAVi. The algorithm uses a method to extract features, based on silhouettes. The challenge is that in MuHAVi these silhouettes are noisy and in many cases include shadows. As there are many actions that need to be recognised, we take a multiclass classification ap-proach that combines binary SVM classifiers. The results are compared with previous results on the same dataset and show a significant improvement, especially for recognising actions on a different view, obtaining overall accuracy of 85.5% and of 93.5% for leave-one-camera-out and leave-one-actor-out tests respectively.Sergio A Velastin has received funding from the Universidad Carlos III de Madrid, the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement no. 600371, el Ministerio de Economía, Industria y Competitividad (COFUND2013-51509) el Ministerio de Educación, cultura y Deporte (CEI-15-17) and Banco Santander

Database of corporate bonds from Argentina

This document describes the construction of a database of corporate bonds issued by firms in Argentina between 1989 and 2005. The database draws on two main sources, the Bolsa de Comercio de Buenos Aires and the Comisión Nacional de Valores, while some additional information comes from the Mercado Abierto Electrónico. In all, we collected information on 1356 corporate bonds, though there are some bonds that have fields with missing information. Our data basically covers the characteristics of the bonds at time of issue. That is, we do not have a detailed description of how the characteristics of those corporate bonds that defaulted in 2001/2002 and were subsequently renegotiated changed. Based on the data from the primary markets, we constructed a series with the total outstanding stock of corporate bonds over this period. The information in the database allows to calculate these stocks at the firm level.primary markets, corporate bonds, institutional framework

Estrés y técnica de arbitraje en baloncesto en función del género

El propósito de estudio ha sido conocer las diferencias en función del género en la intervención técnica del árbitro y las situaciones de estrés que se presentan durante un partido de baloncesto. La muestra consta de seis árbitros de categoría nacional (4 hombres y 2 mujeres), durante la celebración de un torneo internacional U-16. Para conocer las diferencias en la intervención técnica se ha empleado el instrumento IOVAB y para observar las diferencias en las situaciones de estrés el cuestionario LISEA. Los resultados muestran que no existen diferencias significativas en la intervención técnica, exceptuando los movimientos de árbitro de cabeza, donde las mujeres obtienen valores más elevados. Por contra, si se reflejan diferencias entre grupos en las situaciones de estrés. Las mujeres poseen valores más altos cuando se hace referencia al nombre de los entrenadores y jugadores, al puesto que ocupa cada equipo en la competición, al compañero de arbitraje, a la localidad y pabellón en el que arbitran y a la existencia o no de delegado de campo. Los resultados muestran la necesidad de realizar un programa de intervención para regular esta ansiedad antes y después de los partidos.The aim of this research was to determine the differences that may exist in the gender of the referee about the technical intervention and stressful situations during basketball matches. The subjects are six national referees (4 men and 2 women) officiating an international tournament U-16. IOVAB instrument has been used to calculate the differences in the technical intervention and LISEA questionnaire in order to observe differences in stress situations. The results show no significant differences in technical intervention, except the head referee movements, where the women performance is better. However, there are differences between groups in stressful situations. Women have higher values in reference to the name of the coaches and players, the position occupied by each team in the competition, the workmate referee, the place and stadium and the existence of field official. Results show the need to implement an intervention program to regulate the anxiety of the referees before and after the games

Salvador Dalí y el método paranoico-crítico, visión desde el psicoanálisis

Surrealismo y psicoanálisis, dos movimientos que buscaban liberar al sujeto de sus represiones, mantuvieron una relación cercana desde distintas perspectivas, la cual alcanzó su apogeo bajo la representación de sus principales referentes, Sigmund Freud, André Breton y Salvador Dalí. Este último se destaca por su deseo intenso de acercarse al analista austriaco, una vez se aproximó a la obra psicoanalítica, corriente de pensamiento que influiría en su obra artística y vida personal. En este sentido, se realiza una revisión sistemática de literatura con la intención de reconocer la influencia de la obra psicoanalítica en la vida y obra de Salvador Dalí. Se encontró que la relación entre la corriente de pensamiento y el artista español se ubica en el plano teórico y personal. Siendo admirador de las ideas psicoanalíticas, Salvador Dalí las incorpora como fundamento teórico del método paranoico-crítico, propuesta de creación artística, dando lugar a la paranoia como elemento sistematizador de la confusión.Surrealism and psychoanalysis, two movements that sought to free the subject of its repressions, maintained a close relationship from different perspectives, which reached its maximum under the representation of its main referents, Sigmund Freud, André Breton and Salvador Dalí. The latter stands for its intense desire to approach to the Austrian analyst, once he approached to the psychoanalytic work, trend of thought that influenced his artistic work and personal life. In this sense, a systematic review of literature was performed with the aim of recognizing the influence of the psychoanalytic work in the Salvador Dalí´s life and work. It was found that the relationship between this trend of thought and the Spanish artist is located in the theoretical and personal plane. Being an admirer of the psychoanalytical ideas Salvador Dalí incorporates them as theoretical foundation of the paranoiac-critical method, a proposal of artistic creation, giving place to paranoia as a systematizer element of confusion

Electroreactivity of isopropanol on platinum in acids studied by DEMS and FTIRS

The reactivity of isopropanol on polycrystalline Pt in acid solutions was investigated using in-situ Fourier transform IR spectroscopy (FTIRS) and on-line differential electrochemical mass spectrometry (DEMS). The electro-oxidation products are acetone and CO2; the former is observed when isopropanol is present in the bulk of the solution, and the latter is produced from strongly adsorbed species. Both bulk and adsorbed isopropanol electro-reduction yield propane. H-D exchange is observed during propane formation when the reaction takes place in a D2O + DCIO4 solution. This observation suggests the formation of adsorbates bonded to the surface through the C ∝ atom of the isopropanol molecule. FTIR spectra of adsorbed species show the presence of -CH3 and -COH groups. The most probable adsorbate structures are (CH3-C-CH3)Pt, (CH3-CH-CH3)Pt and (CH3-COH-CH3)Pt, presumably accompanied by (CH3-CO-CH3)Pt.Instituto de Investigaciones Fisicoquímicas Teóricas y AplicadasFacultad de Ciencias Exacta

A study on the performance of distributed training of data-driven CFD simulations

Data-driven methods for computer simulations are blooming in many scientific areas. The traditional approach to simulating physical behaviors relies on solving partial differential equations (PDEs). Since calculating these iterative equations is highly both computationally demanding and time-consuming, data-driven methods leverage artificial intelligence (AI) techniques to alleviate that workload. Data-driven methods have to be trained in advance to provide their subsequent fast predictions; however, the cost of the training stage is non-negligible. This article presents a predictive model for inferencing future states of a specific fluid simulation that serves as a use case for evaluating different training alternatives. Particularly, this study compares the performance of only CPU, multi-GPU, and distributed approaches for training a time series forecasting deep learning model. With some slight code adaptations, results show and compare, in different implementations, the benefits of distributed GPU-enabled training for predicting high-accuracy states in a fraction of the time needed by the computational fluid dynamics solver

eCharacter: una herramienta libre para la creación de personajes 3D

eCharacter es una herramienta de software libre que permite la personalización de modelos 3D para su inclusión en videojuegos. Ofrece al usuario la posibilidad de crear nuevos personajes partiendo de varios modelos base mediante una herramienta sencilla de usar, flexible e intuitiva. El proyecto trata de reducir los costes de creación de recursos artísticos para videojuegos, simplificando de esta manera el proceso de desarrollo. Aunque eCharacter puede utilizarse en la creación de personajes para una gran variedad de videojuegos, inicialmente está diseñada y optimizada para prototipado rápido y para su aplicación en proyectos de bajo coste. Por ello se ha diseñado eCharacter para su posible integración con otras herramientas de creación de juegos, especialmente aquellas orientadas al ámbito de la educación y dirigidas a usuarios sin conocimientos extensivos en el campo del desarrollo y la programación de videojuegos. Los videojuegos tienen cada vez más repercusión en la sociedad, y hoy en día, es una industria que está en auge. El uso de los videojuegos no sólo se limita al ocio sino que se está extendiendo a otros campos como el de la salud y la educación en los que los presupuestos de creación de los juegos normalmente son mucho más limitados. Por este motivo, cada vez están surgiendo más herramientas para crear videojuegos, muchas de ellas gratuitas y libres, de una manera sencilla y rápida para el usuario. Este tipo de herramientas, supone un gran ahorro económico para los usuarios que necesitan crear un videojuego simple y que no disponen ni de conocimientos técnicos ni de recursos económicos para realizarlo. Sin embargo, uno de los principales problemas a los que se exponen los usuarios de estas plataformas libres y gratuitas es la obtención de recursos artísticos de alta calidad. Aunque la red proporciona multitud de recursos para obtener modelos 3D, sigue siendo complejo encontrar personajes 3D animados que se ajusten a las necesidades de proyectos no dirigidos al género de acción. Es ahí donde eCharacter pretende ser una contribución significativa, proporcionando a la comunidad una aplicación libre que permite crear de una manera sencilla y gratuita diferentes modelos 3D animados, según las necesidades de los usuarios y que sea fácilmente integrable con otras herramientas. Además tanto eCharacter como todos los recursos gráficos que incluye son gratuitos, permitiendo al usuario facilitarle la tarea en el proceso de creación de los modelos sin que le suponga coste alguno. [ABSTRACT] eCharacter is free software that allows customization of 3D models for video games. It provides the user with a simple and flexible tool to create personalized animated characters for video game development. The project aims to help cut down development costs for creation of art assets for video games, making the whole development process simpler, easier and affordable to more people. Although eCharacter can be used to create characters for a wide range of video games, it has been optimized for applications in rapid prototyping and low cost projects. eCharacter has been designed for easy integration with other games creation tools, especially those that are oriented to education and target users that are not professionals in videogame development and programming. Video games are undoubtedly a consolidated sector of the entertainment industry and have gained deep social acceptance. Moreover, the use of video games is not limited to leisure any more. Instead, it is spreading to other fields like education or health. In this kind of fields the budget for video games creation is more limited. Consequently, there are increasingly more free software tools becoming available for creating video games quickly and easily. This kind of tools are extremely useful for users who need to create simple video games and they have neither the experience nor the financial resources to do it. However, it is still problematic to gather high quality art assets, especially for some types of assets. Although the web is full of sources of 3D models and other art designs for games, free 3D animated models are still scant and they are not always compatible with free software technology. In this case is where eCharacter aims to contribute back to the community with free application that allows creating different 3D animated models and that can be easily integrated with other tools

Reproduction in Goats

Reproductive activity of the goat begins when the females reach puberty, which happens at 5 months of age. The ovarian or estrous cycle is the period between two consecutive estrus. It is also the time that lasts the development of the follicle in the ovary, until rupture occurs and ovulation takes place, which coincides with the appearance of estrus. This chapter will describe the physiological and endocrinological bases of estrus in the goat. Likewise, factors affecting the presence of estrus and ovulation will be described. At another point, synchronization of estrus and ovulation, factors affecting the presence of estrus and external symptoms of estrus, will be described. To achieve synchronization of estrus or induction of ovulation within or outside the breeding season, it may be necessary to manage light hours, male effect, and/or use of hormones. The importance of artificial insemination is described, as well as the current situation of this technique worldwide. Currently, the techniques of artificial insemination in goats have been limited worldwide, due to the lack of resources of producers and trained technicians. The techniques of artificial insemination with estrous synchronization programs and ovulation with current research results will be described
