Planificador de recursos estratégicos para la gestión contable de las PYMEs
El objetivo principal de este proyecto de fin de carrera es el de presentar una de las líneas de
trabajo que desarrollamos en el marco de un convenio específico universidad-empresa. La
labor que venimos desarrollando desde hace algún tiempo parte de una necesidad, apenas
satisfecha en las pequeñas y medianas empresas (pymes). Concretamente, nos referimos al
tratamiento e implementación de herramientas informáticas de gestión integral como
herramientas de soporte en la gestión de las empresas de reducido tamaño. Dada la extensión de nuestro proyecto, este trabajo de fin de carrera se basa exclusivamente
en la puesta en práctica de planificadores de recursos estratégicos en el área de contabilidad
de una pyme. Por tanto, a lo largo de este texto mostraremos las distintas fases que hemos
llevado a cabo para adaptar e implantar una herramienta informática que facilite la gestión de
la actividad contable-financiera en una PymeEscuela Técnica Superior de Ingeniería IndustrialUniversidad Politécnica de Cartagen
Estudio analítico e influencia de la seguridad en buques mercantes y de pasaje
[Resumen]
Hoy en día la seguridad ha adquirido una importancia vital. La evolución que ha experimentado en el siglo XX en los buques mercantes y de pasaje, desde el trágico accidente del “Titanic” nos ha llevado a cotas altamente seguras, inimaginables hace apenas 50 años. El gran avance y la transferencia de tecnología a nivel global, nos permite construir buques seguros, en un entorno competitivo, sin renunciar a unos estándares mínimos. Al mismo tiempo, hay que inspeccionar continuamente el estado de los buques durante su vida útil, gestionando un mantenimiento adecuado. Para que todo esto produzca un resultado satisfactorio, una serie de organismos internacionales, administraciones nacionales, sociedades de clasificación, astilleros, equipos técnicos y otros, deben de velar para que la aplicación de las normas se cumpla. Dotando de seguridad al buque. Lo más importante que hay que preservar es la seguridad de la vida humana en el mar, la prevención de riesgos y el buen funcionamiento del sistema “buque”, evitarán en la medida de lo posible, el accidente marítimo. En el caso de que este se produzca, disponemos de dispositivos y de sistemas de rescate para salvar a las personas. Por si fuera poco trabajar en un entorno hostil, como es la mar, hay una serie de amenazas contra la seguridad que exigen unas medidas de protección, el terrorismo, el polizonaje y la piratería, acechan al marino y a las navieras en muchas zonas del mundo. Estos tres pilares son en los que enmarco esta investigación, que nos aportarán novedosos resultados, necesarios para la mejora de la seguridad.[Resumo] Hoxe en día a seguridade adquiriu unha importancia vital. A evolución que experimentou no século XX nos buques mercantes e de pasaxe, dende o tráxico accidente do "Titanic" nos levou a cotas altamente seguras, inimaxinables hai apenas 50 anos. O grande avance e a transferencia de tecnoloxía a nivel global, permítenos construír buques seguros, nun ámbito competitivo, sen renunciar a uns estándares mínimos. Ao mesmo tempo, hai que inspeccionar continuamente o estado dos buques durante a súa vida útil, xestionando un mantemento axeitado. Para que todo isto produza un resultado satisfactorio, unha serie de organismos internacionais, administracións nacionais, sociedades de clasificación, estaleiros, equipos técnicos e outros, deben de velar para que a aplicación das normas se cumpra. Dotando de seguridade o buque. O mais importante que hai que preservar é a seguridade da vida humana no mar, a prevención de riscos e o bo funcionamento do sistema "buque", evitarán na medida do posible, o accidente marítimo. No caso de que este se produza, dispoñemos de dispositivos e de sistemas de rescate para salvar as persoas. Por se fose pouco traballar nun ámbito hostil, como é o mar, hai unha serie de ameazas contra a seguridade que esixen unhas medidas de protección, o terrorismo, a polizonaxe e a pirataría, axexan o mariño e as navieiras en moitas zonas do mundo. Estes tres piares son nos que enmarco esta investigación, que nos achegarán novidosos resultados, necesarios para a mellora da seguridade.[Abstract] Nowadays the safety has become vital. The evolution that experimented in the 20th century in the merchant and passenger ships, since the tragic accident of the "Titanic" has led to highly safe, unimaginable heights just 50 years ago. The great advance and the transfer of technology to global level, allows to us to build safe ships, in a competitive area, without renouncing some minimum standards. At the same time, the state of the ships during his lifetime has to be inspected continuously, managing an adequate maintenance. So that all this causes a satisfactory result, a series of international organisms, national administrations, societies of classification, shipyards, technical staffs and others, they must watch so that the application of the norms is filled in. Endowing the ship with safety. The most important thing is to preserve the safety of life at sea, the prevention of risks and the good functioning of the system "ship", will prevent as much as possible, the maritime accident. In the event that this occurs, we have devices and rescue systems to save people. To make matters worse working in a hostile environment, such as the sea, there are a number of security threats that require protection measures, the terrorism, the stowaways and the piracy, threaten the marine and shipping in many parts of the world
These are the three pillars that framed this research, which will bring us new results needed to improve safety
Dimensionality reduction methods for machine translation quality estimation
The final publication is available at Springer via http://dx.doi.org/10.1007/s10590-013-9139-3[EN] Quality estimation (QE) for machine translation is usually addressed as a regression problem where a learning model is used to predict a quality score from a (usually highly-redundant) set of features that represent the translation. This redundancy hinders model learning, and thus penalizes the performance of quality estimation systems. We propose different dimensionality reduction methods based on partial least squares regression to overcome this problem, and compare them against several reduction methods previously used in the QE literature. Moreover, we study how the use of such methods influence the performance of different learning models. Experiments carried out on the English-Spanish WMT12 QE task showed that it is possible to improve prediction accuracy while significantly reducing the size of the feature sets.This work supported by the European Union Seventh Framework Program (FP7/2007-2013) under the CasMaCat project (grants agreement no. 287576), by Spanish MICINN under TIASA (TIN2009-14205-C04-02) project, and by the Generalitat Valenciana under grant ALMPR (Prometeo/2009/014).González Rubio, J.; Navarro Cerdán, JR.; Casacuberta Nolla, F.

A comparison between experimental and theoretical excitation functions for the O+ + H2 (4A'') system using trajectory calculations over a wide energy range
The O++H2 prototypic ion-molecule reaction was recently studied in our group using the quasiclassical trajectory method on a ground model potential‐energy surface of the system inferred from both experimental and theoretical information and reasonable assumptions, fitted using a London-Eyring-Polanyi-Sato surface modified to include an ion-induced‐dipole interaction term. The theoretical results previously reported agreed rather well with the available experimental information. In view of the latest experimental findings, we present in this contribution the results of new trajectory calculations on the above‐mentioned surface, covering a wide range of relative translational energies of reactants. The accord between the experimental determinations and the present theoretical evaluations is excellent at relative energies below 1.0 eV, while for higher energies the potential‐energy surface, even though still yielding reasonably good results, provides a worse agreement. The observed discrepancies should be attributed either to the too attractive character of the surface or to the interfering influence of the competing O++H2→O+H2+ charge‐transfer process
The importance of water in traditional gypsum works
Until the second half of the 20th century, the traditional architecture of the Iberian Peninsula was directly linked to the resources available in its immediate surroundings, naturally diversification the built heritage throughout the territory. In its gypsiferous areas, we find a great versatility of construction systems in which the main binder used is traditional gypsum, although this material has been forgotten in the 20th and the 21st century architecture, meanwhile industrial gypsum currently plays a secondary role in the construction sector. Gypsum, like any traditional binder, is a material that is particularly sensitive to the amount of water with which it is mixed, which will be strongly linked to the technique of application, among other technological parameters. Thus, the final performance of the product is, among other things, a consequence of this water/gypsum ratio, as Francisco Arredondo states in some of his works. In them, the behaviour of an industrial gypsum is analysed as a function of the mixing water, relating it in turn to other parameters such as compressive strength, water absorption and bulk density. The aim of this work is to study the influence of the mixing water on the physical and mechanical properties of different traditional plasters, taking into account previous studies, the diversity of traditional uses of gypsum and current application techniquesPeer ReviewedPostprint (published version
