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 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…

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…
