Photopolymers are studied as holographic recording materials for recording computer-generated phase holograms. The recording was performed using a holographic copying process, in which the master is produced by means of a high resolution graphic device. To our knowledge it is…

Les nouveaux dispositifs de formation à distance représentent de nouvelles modalités de formation dans l’enseignement supérieur. Ces dispositifs impliquent l’utilisation d’environnements pédagogiques adaptés qui favorisent les situations de travail collaboratif. La collaboration au sein de ces outils résulte non seulement…

It has been suggested there is a knowledge base that surrounds the use of 3D modeling within the engineering design process and correspondingly within engineering design graphics education. While solid modeling receives a great deal of attention and discussion relative…

Recently, many individuals have been faced with a transfer of learning issue, surrounding the move from one 3-D CAD system to another.  The purpose of this research was to test the hypothesis that, with minimal instruction, users can transfer their…

Engineering and technical graphics professionals have seen major changes in the content and the way we teach our students (Clark & Scales, 2000).  Today, professionals going into fields related to engineering/technical graphics require a broader knowledge of differing forms of…

ROI (Region of Interest) in an image or video signal contains important information and may be used for access control at various qualities using multiresolution analysis (MRA). This paper proposes quality access control method of compressed color image by modulating…

Spatial ability research has been approached from several psychological vantages since its beginnings in the late 1800s. This contribution attempts a summation of spatial ability research, beginning with a historical vignette and a major section on each psychological approach including…

El diseño de programas de actualización profesional es un proceso complejo en el que se conjugan aspectos instruccionales, estructurales, organizativos y tecnológicos muy particulares. La estructura del programa, los modos de interacción facilitador-participante, la forma y estructura de los contenidos…

Le decept es entendido como la distancia entre las creencias de los individuos y el movimiento de la historia, la existencia de un tiempo individual y uno colectivo, conformada la primera en un movimiento soportado por la espera y el…
