We use projection operators to address the coarse-grained multiscale problem in harmonic systems. Stochastic equations of motion for the coarse-grained variables with an inhomogeneous level of coarse graining in both time and space are presented. In contrast to previous…

Accurate and reliable neutron-capture cross-section data for actinides are necessary for the proper design, safety regulation, and precise performance assessment of transmutation devices such as Fast Critical Reactors or Accelerator Driven Systems. In particular, the…

En este trabajo se recogen dos de los problemas que aparecen a la hora de resolver numéricamente las ecuaciones de Navier-Stokes. La discretización en la variabletemporal en dichas ecuaciones nos conduce, en cada etapa de tiempo, a un problema de Burgers y un problema de Stokes…
The integral methods are extensively used for the kinetic analysis of solid-state reactions. As the Arrhenius integral function [p(χ)] does not have an exact analytical solution, different approximated equations have been proposed in the literature for performing the kinetic…

La comunidades autónomas españolas, una uez completado el traspaso de competencias en materia de promoción turistica por el Estado central, están realizando denodados esfuerzos por captar la mayor cuota posible del mercado turistico nacional e international. La aplicación de los…
To obtain a bigger number of mathematical and physical applications of the Santilli’s isotheory, the latest studies have shown the necessity of analyzing isotopic models which use non associative laws. The main goal of this paper is to give a generalization of the isotopic…

El presente trabajo intenta dar cuenta de la repercusión que sobre los niños tiene la separación y/o divorcio de sus padres así como el presenciar el maltrato doméstico sin ser víctimas directas. Tras una breve descripción de ambas situaciones, se explican las posibles…
El objetivo de nuestro estudio es, por un lado, avanzar en el conocimiento de las causas que pueden provocar un cambio en la alta dirección de la empresa, y, por otro, conocer los factores que pueden influir en el origen del sucesor, considerando algunas de las variables que…
The phase transition around the critical point in the evolution from spherical to deformed γ-unstable shapes is investigated in odd nuclei within the interacting boson fermion model. We consider the particular case of an odd j=3/2 particle coupled to an even-even boson core that…

TOC apareció en los años 80 y su funcionamiento se basa en la explotación las restricciones del sistema. TOC tiene una implementación a nivel operacional, conocida como el sistema DBR (Drum-Buffer-Rope) de control de la producción, el cual trata de sincronizar la entrada de los…
The incredible successfulness of the Internet has paved the way for an industry devoted to developing and running web services. Our main goal in this research project is to provide a framework for the agile development and maintenance of applications that build on them. In this…
Erosion mapping is essential for the knowledge of the distribution and geography of erosive processes as well as for its quantitative characterization. The methodology used in this paper is a basis for identifying areas with high erosion risk. It also makes possible to study the…
La revolución tecnológica de los últimos años, que permite la utilización de Internet como vehículo de transmisión de información financiera por parte de las compañías, conlleva la necesidad de que tal emisión se regule para que los usuarios externos puedan acceder con la…
The early stages of the infection of attached leaves and petioles of strawberry (Fragaria ×ananassa Duch. ‘Camarosa’) by Colletotrichum acutatum Simmonds were studied using scanning and transmission electron microscopy. Pre-penetration events of these tissues were similar, but…

Foe is probably not J.M. Coetzee's best known novel, although it is a text of great importance because of the way in which its political, literary and theoretical values are interrelated. The novel addresses a foundational myth of Western societies in the figure of Robinson…
We investigate the finite-size scaling exponents for the critical point at the shape-phase transition from U(5) (spherical) to O(6) (deformed γ-unstable) dynamical symmetries of the interacting boson model, making use of the Holstein-Primakoff boson expansion and the continuous…

Procuramos una solución en el ámbito lingüístico textual en aras de un nuevo discurso periodístico, para contribuir a la supervivencia del periodismo impreso en el entorno digital multimedia, mediante la captación pragmática de la atención del destinatario, lejos de toda fórmula…
Orthodox caliph cUmar emitted the first Muslim currencies. These had religious inscriptions..The coins of gold and copper of the Byzantine Empire, and the coins of silver of the Sasanian Empire were imitated. Later, the fifth Umayyad caliph, Abd al-Malik b. Marwan, reformed the…
The usual distance between pairs of vertices in a graph naturally gives rise to the notion of an interval between a pair of vertices in a graph. This in turn allows us to extend the notions of convex sets, convex hull, and extreme points in Euclidean space to the vertex set of a…

La promoción de la actividad empresarial se considera hoy en día un instrumento de primer orden para mejorar la competitividad y el grado de desarrollo de las economías. La educación empresarial se está erigiendo en una herramienta muy destacada en este sentido. Sin embargo…
We find a great number of works in marketing literature that study the effect moderator of the environment in the relationship among market orientation and performance. In spite of strong supports theoretical that has been developed on this issue, actually there are few empiric…
Nesta comunicação serão comentadas as vantagens de inserir na estratégia da empresa práticas de responsabilidade social motoras da eficiência empresarial, as quais serão também importantes como elementos dinamizadores do desenvolvimento da comunidade local. Neste sentido será…
El avance del periodismo digital está planteando ya la necesidad de encontrar nuevas fórmulas narrativas y formales específicas para cada medio, que no estén tan estrechamente ligadas a los diarios impresos como hasta ahora. La supervivencia de los actuales géneros…
Current P systems which solve NP–complete numerical problems represent instances in unary notation. In classical complexity theory, based upon Turing machines, switching from binary to unary encoded instances gen erally corresponds to simplify the problem. In this paper we show…
En este trabajo exponemos nuestra propuesta de plan docente adaptado al sistema europeo de créditos ECTS y la valoración de la experiencia piloto de la Diplomatura en Turismo de la Escuela Universitaria de Estudios Empresariales de la Universidad de Sevilla, tanto por parte de…
The motion of neutral particles with magnetic moments in an inhomogeneous magnetic field is described in a quantum mechanical framework. The validity of the semiclassical approximations which are generally used to describe these phenomena is discussed. Approximate expressions…

The EurOMA-sponsored THENEXOM network has been approved by the European Commission through its Socrates community action programme. THENEXOM’s short-term goal is to analyse the present state of Operations and Supply Chain Management in European universities and to identify…
El presente artículo, esbozo de una investigación más amplia, pretende analizar la transmisión y contenidos de los medios de comunicación y estudiar cómo se asumen éstos por parte de los receptores y observar también si los valores educacionales tradicionales son transmitidos o…
The main goal of this study is to develop a scientific method for designing a teaching methodology used in a basic digital signal processing (DSP) course. The proposed method is based on concept-mapping techniques, which applies multivariate statistic analysis to summarize the…
