This paper examined the issue of access to higher education, the transformation of this process based on social demands and the principles of access policies. Admission processes in Latin American universities were analyzed and the different criteria, ways and mechanisms for the selection of students were assessed. Aspects related to Software Engineering methodologies and tools for the development of computer models and computer systems to support the admission process were investigated. Due to the importance of having a software to attend the constant improvement of the admission processes in the universities, special attention is given in this article to the principles of the object oriented design and to the use of patterns in this activity.

A computational model for the thumb was developed in order to evaluate the stresses and strains in the Trapeziometacarpal joint under physiological conditions. A reconstruction of the 3D geometry of the thumb was performed through image processing of computerized axial tomographies. Based on anatomical and functional analysis of the thumb, a computational model was generated to simulate the behavior of the joint under normal working conditions. The tendon forces and the distribution of stresses in the joint were obtained by means of mechanics analysis using the finite element method; these analyses were performed for regular usage conditions and specific anatomical grip positions.

A computational model of neuronal net closely related with the formation of equivalence classes is developed. First the formal pattern of the neuronal net is presented and then its operation and its direct relationship with the phenomenon of the formation of the equivalence classes and with the derived relationships are explained. Later on, the validation of the pattern is described carrying out several simulations allowing verification of the pattern so it is able to generate relationships not explicitly trained, these results being adjusted to the basic results of this investigation line. These simulations were carried out using a training of classic conditioning and a test phase by means of conditional discriminations. [ABSTRACT FROM AUTHOR]

A Structural Analysis was made in this work to determine the state of deformations and stresses for the vacuum press shell under normal operating conditions. Once the deformations and stresses distributions were known, a fatigue analysis was made to evaluate the convenience of future surface grinding operations. The maximum deflection calculated in the model was in accordance with the real setting for the couch roll crown currently in use, which secures a contact NIP that is approximately constant along the axial direction.
