El propósito de este artículo es ofrecer una primera aproximación crítica a
la contribución de Hayden White a la teoría del conocimiento histórico. En la
primera parte, se presentan aquellos elementos de esa contribución que se consideran más genuinos y…

Modeling is one of the most important activities throughout any software development life cycle. Within object-oriented modeling, class generalization is a powerful, yet simple concept for abstracting commonalities between classes. Although, as classes evolved in the model, their semantics may…

This paper introduces the system simulation technique and looks for potential application in the biodiesel agribusiness. The simulation basics are presented. It's described the components of a simulation model, the models classification and the model construction process. Some uses in…

Characterizations of the containment of a convex set either in an arbitrary convex set or in the complement of a finite union of convex sets (i.e., the set, described by reverse-convex inequalities) are given. These characterizations provide ways of verifying…

This work describes a way to map complex and / or multivalued attributes from a visual query environment to relational databases, using XML. These attributes are usually produced after the application of integration methodologies, like ERC+, whenever exists in original…

The central thesis of this report is that human language is NP-complete. That is, the process of comprehending and producing utterances is bounded above by the class NP, and below by NP-hardness. This constructive complexity thesis has two empirical consequences.…

Determining an optimal schedule to minimize the completion time of the last job abandoning the system (makespan) becomes a very difficult problem when there are more than two machines in the flow shop. Due both to its economical impact and…

El problema que da origen a este desarrollo se debe a la dificultad que tienen los estudiantes al abordar el tema de la robótica utilizando los materiales bibliográficos y las explicaciones teóricas. Por este motivo, se pensó en un software…

The present article deals with some sociopolitical aspects completely
necessary to understand the current situation of Basque language.
After introducing some general aspects, conditions and development
of the process of linguistic standardization are taken into account in
the Basque territories…

Dynamic systems which undergo rapid motion can excite natural frequencies that lead to residual vibration at the end of motion. This work presents a method to shape force profiles that reduce excitation energy at the natural frequencies in order to…
