16. Design da interação em ambientes virtuais : uma abordagem semiótica
Virtual environments, also called virtual reality systems, are computational enviromnents that incorporate a style of Human-Computer interaction in which the signs to which hmnan beings are exposed, are generated by the computer in accordance with the point of view" of an individual participant. Early directed to scientific applications and to high-cost simu

17. Simulation of thin strip continuous casting of steels / Simulação do lingotamento continuo de tiras finas de aços
It can be understood by process modeling the development of a quantitative or qualitative representation of the physical phenomena associated to the process. In this work, simulations concerning the twin roll continuous caster of steels process at IPT (Instituto de Pesquisas Tecnológicas do Estado de São Paulo) are performed. Two simulators were developed:

18. SYNTHESIS OF ELECTRONIC CIRCUITS FOR EVOLUTIONARY COMPUTING / SÍNTESE DE CIRCUITOS ELETRÔNICOS POR COMPUTAÇÃO EVOLUTIVA
This thesis investigates the application of evolutionary computing techniques in the synthesis of electronic circuits. Evolutionary computation encompasses a particular class of algorithm which employ some aspects of natural evolution as metaphors. Particularly, most of these algorithms borrow ideas from the natural selection, genetic material recombination

19. Modelagem hidrodinamica de um mecanismo pulso duplicador
Pulse duplicators simulators are useful devices in biomedical applications. They can simulate in vitro flow phenomena related to arterial blood flow such as: stenosis, aneurysms, bifurcations, vessel elasticity among others. The purpose of this work is two-fold: develop mathematicaltools to model and analyze pulse duplicators simulators and the propose a new

20. Agregacao de defeitos induzida pelo Al3+ Em solucões sólidas de fluoreto De cálcio com Yb3+ E La3+ / Aggregation defects induced by Al 3 + in solid solutions of calcium fluoride with Yb3 + and La3 +
Apresentamos, pela primeira vez, estudos empregando Simulações Computacionais Estáticas e TSPC e TSDC de soluções sólidas de CaF2 com AIF (de 0,004 a 0,05 mol%), YbF3 e LaF? (- 0,l moi%). Os espectros de TSDC revelaram que: i) abaixo de 270K, as amostras só com Yb3+, La3+ e as multidopadas possuem a banda dos dipolos 1(0(0/11e dos defeitos 1j0/1/21, e

21. SIMULAÇÃO DE REDES COM LINHAS DE TRANSMISSÃO E CARGAS / TRANSMISSION LINE MODEL
This thesis introduces a metodology for the simulation of transmission lines, power generators, interconnnections and loads, base don digital filtering models. These models make intensive use of digital equivalent network concepts in order to solve the computability problem of the digital filter. The result of this work is a system that represents the discre

22. A computational analysis of sequence features involved in recognition of short introns
Splicing of short introns by the nuclear pre-mRNA splicing machinery is thought to proceed via an “intron definition” mechanism, in which the 5′ and 3′ splice sites (5′ss, 3′ss, respectively) are initially recognized and paired across the intron. Here, we describe a computational analysis of sequence features involved in recognition of short
