1. Use of an Artificial Neural Network-based Metamodel to Reduce the Computational Cost in a Ray-tracing Prediction Model
Abstract The purpose of this article is based on analyzing the use of RTQ3D (“quasi-3D” ray tracing technique) to produce the value of the initial electromagnetic fields or fitness for a hundred and sixty receivers according to the possible positions of two antennas to be distributed in a closed environment. The problem variables consist of the values of

2. Método para visualização de campos tensoriais tridimensionais baseado em rastreamento de partículas
Campos tensoriais arbitrarios s~ao uteis em diversas areas do conhecimento como a fsica, engenharias e areas da saude. Um dos principais interesses de prossionais destas areas e a investigac~ao de objetos colineares e coplanares representados pelos tensores. Esses objetos s~ao formados por subconjuntos estruturados de tensores presentes no campo e que captur

3. Integração de sistemas de partículas com detecção de colisões em ambientes de ray tracing / Integration of particle systems with colision detection in ray tracing environments
Encontrar um modo de criar imagens fotorealísticas tem sido uma meta da Computação Gráfica por muitos anos [GLA 89]. Neste sentido, os aspectos que possuem principal importância são a modelagem e a iluminação. Ao considerar aspectos de modelagem, a obtenção de realismo mostra-se bastante difícil quando se pretende, através de técnicas tradiciona

4. The structure of alfalfa mosaic virus capsid protein assembled as a T=1 icosahedral particle at 4.0-A resolution.
K. Fukuyama, S. S. Abdel-Meguid, J. E. Johnson, and M. G. Rossmann (J. Mol. Biol. 167:873-984, 1983) reported the structure of alfalfa mosaic virus assembled from the capsid protein as a T=1 icosahedral empty particle at 4.5-A resolution. The information contained in the structure included the particle size, protein shell thickness, presence of wide holes at

5. Asynchronous Synthesis of the Complementary Strands of the Reovirus Genome
The mechanism of replication of the double-stranded RNA genome of reovirus has been analyzed by tracing the fate of the parental double-stranded RNA genome and by determining whether the complementary strands, which comprise the progeny double-stranded RNA, are synthesized simultaneously or sequentially. The results indicate that the parental double-stranded

6. Nested Duplex PCR To Detect Bordetella pertussis and Bordetella parapertussis and Its Application in Diagnosis of Pertussis in Nonmetropolitan Southeast Queensland, Australia
A duplex PCR to detect Bordetella pertussis and Bordetella parapertussis was developed with the insertion sequences IS481 (B. pertussis) and IS1001 (B. parapertussis) and evaluated with specimens from 520 consecutive patients presenting with possible pertussis. No culture-positive–PCR-negative results occurred, giving the method a sensitivity of 100%. For
