Efeitos Visuais, uma Abordagem a Partir do Processamento Digital de Imagens
This article introduces the most important concepts of digital images and discusses how they are used to create visual effects. At the same time, it overviews various techniques of computer graphics and image processing for cinema and video. Visual effects production uses intensively geometrical modeling, computer visualization, digital image processing and, more recently, computer vision. The ...

The mechanisms for intraseasonal variability of the southern hemisphere (SH) winter are studied using a nonlinear non-divergent barotropic potential vorticity model on the sphere. The possibility of low frequency unstable modes induced by topography is examined to compare with the northern hemisphere (NH) case. According to this simple model for the SH winter the most important mechanism in cre...

The objective of this paper is to present some of the issues faced by those whose interest is to predict responses in poultry, concentrating mainly on those related to the prediction of voluntary food intake, as this should be the basis of models designed to optimise both performance and feeding programmes. The value of models designed to predict growth or reproductive performance has been impr...

Following the development of more accurate methods for lipid evaluation, various compounds have been discovered and studied as a way to improve and enrich diets to meet the animal requirements. Triglycerides are the major lipid component of diets and source of fatty acids that are used in the synthesis of important compounds as phospholipids. The fatty acids from phospholipids play a fundamenta...

Providing feed is a major input cost in beef production, hence improvements in the efficiency of feed utilisation will reduce the cost of production. Residual feed intake (RFI) is a measure of feed efficiency, and is defined as the difference between an animal's actual feed intake and its expected feed intake based on its size and growth. It is independent of the level of production, and the lo...
