El imperio Disney: La clave de su éxito.

Para este trabajo se ha realizado un documental donde se exploran varios puntos clave, sobre la base del gran éxito de la compañía Disney, a la vez que resuelve una gran pregunta: ¿Cómo lo han conseguido? ¿Cómo han conseguido estar presentes en la memoria de todo tipo de público? Preguntas que se van resolviendo a lo largo del documenta

A Constraint-based Model for Multi-objective Repair Planning

This work presents a constraint based model for the planning and scheduling of disconnection and connection tasks when repairing faulty components in a system. Since multi-mode operations are considered, the problem involves the ordering and the selection of the tasks and modes from a set of alternatives, using the shared resources efficiently. Additionally, delays due to change of configurations and transportation are considered. The goal is the minimization of two objective functions: makespan and cost. The set of all feasible plans are represented by an extended And/Or graph, that embodies all of the constraints of the problem, allowing non reversible and parallel plans. A simple branch-and-bound algorithm has been used for testing the model with different combinations of the functions to minimize using the weighted-sum approach.Ministerio de Educación y Ciencia DIP2006-15476-C02-0

Usabilidad Web: una necesidad para las bibliotecas; un derecho para los usuarios

It defines and develops websites usability issue: features, elements, principles and benefits that result from applying usability in interface design, content organization, user interaction, navigation and information retrieval. The following describes the User-Centered Design, DCU, and comprehensive process of applying the principles of usability to the real needs of users. Finally we offer some advice and recommendations to optimize the usability of the Web site of a unit of information

Molecular distribution of wastewater from a meat by-products processing company, treated using a batch system (SBR)

Biological treatments of wastewater depend on the characteristics of organic matter. The molecular weight fractionation of the various components of wastewater is of great importance as it helps to design appropriate treatment technologies. The purpose of this study was to evaluate the distribution of particle sizes present in two types of wastewater generated in a company that processes meat by-products and their respective mixtures. Evaluation was carried out before and after treatment using a discontinuous system in a Sequencing Batch Reactor (SBR). The analysis in the tributaries of the system showed thatmost of the parameters analyzed had a molecular weighthigher than 10,000 Da. The results of the effluents showedthat the SBR system is adequate to remove a high fraction of readily biodegradable organic matter, achieving aremoval order of 98.68%, 98.14% and 70.51% for COD,BOD 5 and NH4+ -N respectively
