Despite the many assumptions that usually surround the importance of science education for scientific practice, scholarship on the history of subject has been scattered and usually undertaken en route to other pursuits. In this research, I aim to bring to…

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…

Intentaremos mostrar la relación de dolor y placer en el arte, partiendo del dolor en Platón, y de las máximas “conócete a ti mismo” y “cuidado de sí”, porque el “conócete a ti mismo” es parte del proceso formativo. Según…

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…

Spatial relationships between two globose cacti (Mammillaria mammillaris (L) Karsten and Melocactus schatzlii Till & Gruber) and two dominant mimosoid shrubs (Acacia farnesiana (Willd.) L. and Prosopis julifora DC.) were evaluated in two habitats (cactus thicket and thornscrub) of a…

El presente ensayo tiene como propósito generar una aproximación teórica para fundamentar, desde una perspectiva
multidimensional, la evidente existencia de un circuito tetralógico: sujeto-empresa-universidad-contexto, en el que se construye «el conocimiento». Es así, como se plantea una investigación que usa…

Constraint-based modeling tools, as well as computer graphics tools in general, offer the user many choices in commands and techniques for creating graphics, which forces the user to have a strategy or plan as they proceed. The formulation of this…
