Researches on Knowledge Discovery in Databases (KDD) was initially oriented toward the definition of new pattern discovery models and the development of the corresponding algorithms. At present, research has focused on issues related to integrating KDD with database systems, to generate systems and tools for KDD whose architectures can be classified in one of three categories: loosely coupled, middly coupled and tightly coupled with a Database Management System (DBMS). In this paper a review of the state of the art on architectures for the process of integrating Knowledge Discovery with a DBMS is presented. It is part of the proposal doctoral research "New primitives SQL for Knowledge Discovery on tightly coupled architectures with a DBMS" that at the moment it is developed by the author of this paper in the program of Ph.D. in Engineering in Computer Science area of emphasis of University of Valley.

In this paper is presented the design and implementation of a ping-pong game on a 7x5 LED matrix based on a microcontroller system. Its implementation involves all processes in typical software development logic, which makes this application to be considered as a pedagogical tool for teaching basic programming content. The design from the perspective of engineering is presented, furthermore is detailed the diagram of the different stages of the system and the structure of the algorithm implemented in the microcontroller. The application allows increase the complexity of programming in so far that increase the conditions and restrictions of operation, generating greater capacity for analysis and alternative solutions.

This paper presents a methodology to reduce energy losses in primary distribution networks, considering a combined algorithm which involves the optimal reconfiguration of the system and phase balance. The mathematical model is nonlinear mixed integer, which takes into account the investment and operating costs of the network, subject to a set of technical constraints imposed by the system. To solve the problem of reconfiguration and phase balance algorithms are used Simulated Annealing and Ant Colony, respectively. The algorithm is tested on IEEE 37 node feeder. [ABSTRACT FROM AUTHOR]

A model for collision detection based on double hierarchical spherical representation is proposed in this paper: an outer spherical representation for detecting no-intersections and an inner spherical representation in order to improve the performance of the collision detector. The algorithm has been implemented. Several tests were conducted with convex polyhedral and the performance of the algorithm was evaluated in terms of the collision between inner spheres. The experimental results show that outer spheres have been useful to determine lack of intersection, whereas inner spheres are more efficient for detecting existence of intersection and for speeding up the process of detecting collision. Using inner spheres improve the general performance because it reduces the number of intersection tests between the faces of the polyhedral. [ABSTRACT FROM AUTHOR]
