Experiences Using an Open Source Sofware Library to Teach Computer Vision Subjects

Machine vision is an important subject in computer science and engineering degrees. For laboratory experimentation, it is desirable to have a complete and easy-to-use tool. In this work we present a Java library, oriented to teaching computer vision. We have designed and built the library from the scratch with enfasis on readability and understanding rather than on efficiency. However, the library can also be used for research purposes. JavaVis is an open source Java library, oriented to the teaching of Computer Vision. It consists of a framework with several features that meet its demands. It has been designed to be easy to use: the user does not have to deal with internal structures or graphical interface, and should the student need to add a new algorithm it can be done simply enough. Once we sketch the library, we focus on the experience the student gets using this library in several computer vision courses. Our main goal is to find out whether the students understand what they are doing, that is, find out how much the library helps the student in grasping the basic concepts of computer vision. In the last four years we have conducted surveys to assess how much the students have improved their skills by using this library.

Nutrición enteral en el estado nutricional del cáncer; revisión sistemática

Objetivo: identificar qué efecto provoca la nutrición enteral en el estado nutricional del cáncer. Método: se realizó una búsqueda con las palabras clave “Cancer” AND “Enteral Nutrition” AND “Supplementation” en cuatro bases de datos documentales: Pubmed, EBSCO, ProQuest y Web of Science. Criterios de inclusión: edad de la muestra, mayores de 18 años; el programa de intervención incluía dieta y empleo o no de suplementación nutricional; ensayos clínicos publicados entre enero de 2004 y diciembre de 2014, en revistas científicas indexadas. Resultados: se han analizado 660 artículos, de los cuales solo han sido incluidos un 2%. El 58% de los programas de intervención son aplicados fuera de España; el 84% de las intervenciones fueron llevadas a cabo en un ambiente hospitalario; el 58% de la muestra está formada por adultos mayores de 54 años; el 33% de las intervenciones fueron multidisciplinares y su duración oscila entre 1 y 4 años. Discusión: se han encontrado pocas intervenciones a nivel nacional y se diferencian en dos tipos: fórmula enteral polimérica exclusiva o mixta junto a inmunonutrición. Conclusión: la nutrición enteral frente a la parenteral y su introducción de forma precoz mejora el estado nutricional del paciente; las fórmulas poliméricas junto a la inmunonutrición ayudan a la reducción del tiempo de hospitalización; los parámetros analíticos se muestran como un patrón de medición a la hora de valorar la mejora en el estado nutricional de los pacientes con cáncer. Se recomienda aumentar la investigación en este campo, sobre todo en niños.

Agua, derecho de uso y utilidad en el regadío de tradición andalusí del Reino de Valencia

El origen de la normativa escrita sobre el uso de las aguas en el territorio peninsular levantino plantea diversas incógnitas. Las primera de ellas sobre los quienes fueron los protagonistas en la redacción y determinación de ese derecho. La segunda sobre el papel que la costumbre de los sarracenos desempeñó en la preservación de tradiciones jurídicas, mantenimiento de infraestructuras y gestión del agua. La tercera tiene que ver con el modo de aunar intereses de comunidades distintas desde el punto de vista religioso y jurídico sobre el derecho de uso de forma equitativa y proporcional a necesidades no necesariamente coincidentes. Lo cierto es que las fuentes conservadas sobre el proceso de reconquista y población siguen siendo una de las mejores referencias para despejar incógnitas y justificar la tradición y pervivencia de un derecho inmemorial y vigente en algunas de sus formas y manifestaciones, no solo en el marco levantino sino en otros muchos espacios de la cuenca mediterránea con idénticas características medioambientales y geo-climáticas.

Phraseological features in conversational routines: An integrative model of autonomy

This paper deals with the analysis of routine formulas according to their degree of independence in discourse, with the aim of establishing a gradual line which restructures Sphere III (Corpas 1996, Alvarado 2015) — where phraseological utterances belong. The system developed by Briz and the Val.Es.Co. Group (2003, 2014) will help us segment conversation and check that phraseological utterances show various degrees of independence, both in Peninsular Spanish and in Latin American Spanish, which will make it possible to restructure Sphere III. The methodology utilized corresponds to the phraseological and pragmatic approach, and the examples were extracted from the Corpus de Conversaciones Coloquiales of Briz and the Val.Es.Co. Group (2002), and from the Corpus Preseea (2014).

Positional accommodative intraocular lens power error induced by the estimation of the corneal power and the effective lens position

Purpose: To evaluate the predictability of the refractive correction achieved with a positional accommodating intraocular lenses (IOL) and to develop a potential optimization of it by minimizing the error associated with the keratometric estimation of the corneal power and by developing a predictive formula for the effective lens position (ELP). Materials and Methods: Clinical data from 25 eyes of 14 patients (age range, 52–77 years) and undergoing cataract surgery with implantation of the accommodating IOL Crystalens HD (Bausch and Lomb) were retrospectively reviewed. In all cases, the calculation of an adjusted IOL power (PIOLadj) based on Gaussian optics considering the residual refractive error was done using a variable keratometric index value (nkadj) for corneal power estimation with and without using an estimation algorithm for ELP obtained by multiple regression analysis (ELPadj). PIOLadj was compared to the real IOL power implanted (PIOLReal, calculated with the SRK-T formula) and also to the values estimated by the Haigis, HofferQ, and Holladay I formulas. Results: No statistically significant differences were found between PIOLReal and PIOLadj when ELPadj was used (P = 0.10), with a range of agreement between calculations of 1.23 D. In contrast, PIOLReal was significantly higher when compared to PIOLadj without using ELPadj and also compared to the values estimated by the other formulas. Conclusions: Predictable refractive outcomes can be obtained with the accommodating IOL Crystalens HD using a variable keratometric index for corneal power estimation and by estimating ELP with an algorithm dependent on anatomical factors and age.

Pharmacopea de la Armada (1760), un libro singular para uso de los sanitarios navales del siglo XVIII

La Pharmacopea de la Armada, obra de Leandro de Vega, publicada en 1760 para uso de médicos y cirujanos de los buques y hospitales de la marina española a lo largo del siglo XVIII, está considerada como la primera farmacopea naval española. Su autor la define con un «catálogo de medicamentos pertenecientes a las enfermedades médicas», en definitiva un nomenclátor de fórmulas para la preparación de los medicamentos de mayor utilidad para los navegantes de la época, tanto de uso interno como externo. En el presente artículo se analiza en profundidad esta obra, reconocida su relevancia de fuente primaria, situándola en su contexto histórico, detallando el contenido de sus tratados, así como dando noticia biográfica de su autor e informando de la posición profesional y misión de sus destinatarios.

Cálculo del asiento elástico tridimensional de cimentaciones de rigidez variable en terrenos con una capa rígida inclinada

Las fórmulas basadas en la teoría de la elasticidad son ampliamente utilizadas para el cálculo de asientos de cimentaciones, ya que la totalidad de la normativa geotécnica recomienda su empleo. No obstante, estos métodos no cubren todas las situaciones geotécnicamente posibles ya que frecuentemente las condiciones geológicas son complejas. En este trabajo se analiza la influencia de la presencia de una capa rígida inclinada en los asientos elásticos de una cimentación superficial. Para ello se han resuelto 273 modelos tridimensionales no lineales de elementos finitos, variando los parámetros clave del problema: la inclinación y la profundidad de la capa rígida y la rigidez de la cimentación. Finalmente, se ha realizado un análisis estadístico de los resultados de los modelos y se ha propuesto una fórmula que puede ser utilizada en el cálculo de asientos por métodos elásticos, para tener en consideración la presencia de una capa rígida inclinada en profundidad.

Sediment and organic matter properties, and molecular formula from sampling locations in the Northern Black Sea

Remineralization of organic matter in reactive marine sediments releases nutrients and dissolved organic matter (DOM) into the ocean. Here we focused on the molecular-level characterization of DOM by high-resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) in sediment pore waters and bottom waters from contrasting redox regimes in the northern Black Sea with particular emphasis on nitrogen-bearing compounds to derive an improved understanding of the molecular transformations involved in nitrogen release. The number of nitrogen-bearing molecules is generally higher in pore waters than in bottom waters. This suggests intensified degradation of nitrogen-bearing precursor molecules such as proteins in anoxic sediments: No significant difference was observed between sediments deposited under oxic vs anoxic conditions (average O/C ratios of 0.55) suggesting that the different organic matter quality induced by contrasting redox conditions does not impact protein diagenesis in the subseafloor. Compounds in the pore waters were on average larger, less oxygenated, and had a higher number of unsaturations. Applying a mathematical model, we could show that the assemblages of nitrogen-bearing molecular formulas are potential products of proteinaceous material that was transformed by the following reactions: (a) hydrolysis and deamination, both reducing the molecular size and nitrogen content of the products and intermediates; (b) oxidation and hydration of the intermediates; and (c) methylation and dehydration.
