Metodología para la resolución de problemas de optimización

El presente proyecto tiene como objetivo evaluar una metodología para la resolución de problemas de optimización. Para ello se utiliza el formalismo de modelado de Redes de Petri Coloreadas para representar un Sistema de Eventos Discretos, que describirá el problema de optimización a resolver. El caso de estudio a optimizar en este proyecto se conoce como Tiempo de Tránsito de Pasajeros, y se define como el tiempo que tarda un pasajero con escalas en recorrer el trayecto que va desde la puerta de embarque de llegada hasta la puerta de embarque de salida asignada.

A multi-perspective approach to performance anxiety in music students

AbstractPerforming publicly has become increasingly important in a variety of professions. This condition is associated with performance anxiety in almost all performers. Whereas some performers successfully cope with this anxiety, for others it represents a major problem and even threatens their career. Musicians and especially music students were shown to be particularly affected by performance anxiety.Therefore, the goal of this PhD thesis was to gain a better understanding of performance anxiety in university music students. More precisely, the first part of this thesis aimed at increasing knowledge on the occurrence, the experience, and the management of performance anxiety (Article 1). The second part aimed at investigating the hypothesis that there is an underlying hyperventilation problem in musicians with a high level of anxiety before a performance. This hypothesis was addressed in two ways: firstly, by investigating the association between the negative affective dimension of music performance anxiety (MPA) and self-perceived physiological symptoms that are known to co-occur with hyperventilation (Article 2) and secondly, by analyzing this association on the physiological level before a private (audience-free) and a public performance (Article 3). Article 4 places some key variables of Article 3 in a larger context by jointly analyzing the phases before, during, and after performing.The main results of the self-report data show (a) that stage fright is experienced as a problem by one-third of the surveyed students, (b) that the students express a considerable need for more help to better cope with it, and (c) that there is a positive association between negative feelings of MPA and the self-reported hyperventilation complaints before performing. This latter finding was confirmed on the physiological level in a tendency of particularly high performance-anxious musicians to hyperventilate. Furthermore, the psycho-physiological activation increased from a private to a public performance, and was higher during the performances than before or after them. The physiological activation was mainly independent of the MPA score. Finally, there was a low response coherence between the actual physiological activation and the self-reports on the instantaneous anxiety, tension, and perceived physiological activation.Given the high proportion of music students who consider stage fright as a problem and given the need for more help to better cope with it, a better understanding of this phenomenon and its inclusion in the educational process is fundamental to prevent future occupational problems. On the physiological level, breathing exercises might be a good means to decrease - but also to increase - the arousal associated with a public performance in order to meet an optimal level of arousal needed for a good performance.

Evolution of ascariasis in humans and pigs: a multi-disciplinary approach

The nematode parasite Ascaris lumbricoides infects the digestive tracts of over 1.4 billion people worldwide, and its sister species, Ascaris suum, has infected a countless number of domesticated and feral pigs. It is generally thought that the putative ancestor to these worms infected either humans or pigs, but with the advent of domestication, they had ample opportunity to jump to a new host and subsequently specialize and evolve into a new species. While nuclear DNA markers decisively separate the two populations, mitochondrial sequences reveal that three major haplotypes are found in A. suum and in A. lumbricoides, indicating either occasional hybridization, causing introgression of gene trees, or retention of polymorphism dating back to the original ancestral species. This article provides an illustration of the combined contribution of parasitology, archaeoparasitology, genetics and paleogenetics to the history of ascariasis. We specifically investigate the molecular history of ascariasis in humans by sequencing DNA from the eggs of Ascaris found among ancient archeological remains. The findings of this paleogenetic survey will explain whether the three mitochondrial haplotypes result from recent hybridization and introgression, due to intensive human-pig interaction, or whether their co-occurrence predates pig husbandry, perhaps dating back to the common ancestor. We hope to show how human-pig interaction has shaped the recent evolutionary history of this disease, perhaps revealing the identity of the ancestral host.

Construcción y explotación de un almacén de datos para el análisis de información inmobiliaria

El objetivo de este Trabajo Final de Carrera (TFC) es consolidar los conocimientos adquiridos a lo largo de nuestros estudios de Ingeniería Técnica en Informática de Sistemas. Es un documento que contiene el enunciado de un problema del mundo real, que se describe, desgrana, analiza, etc, y que al final se detalla la solución técnica final escogida. Este Trabajo Final de Carrera, a partir de ahora TFC, está enmarcado dentro del área de Almacenes de Datos, utilizando el siguiente software: ORACLE EXPRESS v10.2.0.1 y SQL DEVELOPER. La empresa inmobiliaria Un Techo para Todos, tiene un catalogo de inmuebles de España y Andorra. Necesitan un sistema de información que le permita comparar diferentes zonas, tipos de pisos y precios, para intentar ser más eficientes ajustando la oferta y la demanda, y por consiguiente obteniendo mayores beneficios. El principal problema que nos plantean es que aunque disponen de mucha información, esta no la tienen integrada en un sistema informático optimo( lo tienen en unas hojas de Excel), por lo que no pueden sacarle el rendimiento adecuado.
