1. A computational modeling method for root canal endoscopy using a specific CBCT filter: A new era in the metaverse of endodontics begins
Resumo Uma revolução tecnológica contemporânea deu início a uma nova era no metaverso da Endodontia, um mundo de possibilidades operacionais virtuais que utilizam uma réplica exata das estruturas naturais do complexo dentomaxilofacial. Este estudo descreve um método de modelagem computacional para a endoscopia do canal radicular, usando um moderno sof

2. Research on Sliding Mode Method about Three-Dimensional Integrated Guidance and Control for Air-to-Ground Missile
ABSTRACT Based on adaptive sliding mode-control and back-stepping design method, an integrated guidance and control method with less calculation is proposed, which is designed for air-to-ground missile during the terminal course in three-dimensional space. The model of the control system with nonlinear and coupling is simplified, then the integrated guidance

3. Viabilidade de aplicação de malhas virtuais na identificação de sistemas em malha fechada
A identificação de sistemas em malha fechada assume papel importante no contexto atual, já que reduz o custo operacional do processo de identificação no estágio de testes, evitando, por exemplo, a geração de produtos fora de especificação. Entretanto, requer uma série de cuidados especiais no tratamento dos dados a serem analisados para a obtenç�

4. MVC-RA: multiple views on coordinates environments up to reality / MVC-RA: múltiplas visões coordenadas em ambientes de realidade aumentada
This work aims to apply the characteristics of an augmented reality environment such as easy and intuitive interaction and large visualization space to the implementation, interaction and visualization of multiple coordinated data views. Multiple data views provide the user a better data analysis on different aspects. The coordination among multiple views re

5. Um estudo de percepção em ambiente simulado com realidade virtual exploratória / A study of perception in simulated environment with exploratory virtual reality
How do people perceive space simulated by virtual reality and can such resource can be used in the architectural design evaluation process? This is the question which guided this research. An earlier work verified that subjective questions (with a scale of values of efficiency) are less efficient to evaluate the user s perception in a simulated environment w

6. A Numerical and Experimental Evaluation of ERA and ERA/OKID for Mechanical Systems Identification / Avaliação numérica e experimental dos métodos ERA e ERA/OKID para a identificação de sistemas mecânicos
This work presents two algorithms of identification of state-space linear systems, as follows: ERA (Eigensystem Realization Algorithm), developed by Juang and Pappa (1985), and ERA/ OKID (Observer/ Kalman Filter Identification), by Phan et al. (1992). Both were conceived at the environment of Aerospace Engineering, where it was indispensable the appearance o

7. A Numerical and Experimental Evaluation of ERA and ERA/OKID for Mechanical Systems Identification / AvaliaÃÃo numÃrica e experimental dos mÃtodos ERA e ERA/OKID para a identificaÃÃo de sistemas mecÃnicos
Este trabalho apresenta dois algoritmos de identificaÃÃo de sistemas lineares em espaÃo de estados, quais sejam: o ERA (Eigensystem Realization Algorithm), desenvolvido por Juang e Pappa (1985), e o ERA/OKID (Observer/Kalman Filter Identification), por Phan et al. (1992). Ambos foram concebidos no ambiente da Engenharia Aeroespacial, onde se fazia impresc

8. Bounds for the rth characteristic frequency of a beaded string or of an electrical filter
The fundamental mode of vibration of a beaded string has a shape without change of sign. The rth higher normal mode of vibration has r changes of sign. Given any virtual shape of the string with r changes of sign, an algorithm is found that gives upper and lower bounds for the rth characteristic frequency as a function of the virtual shape. By making a certa

9. An in vitro model for immune control of chlamydial growth in polarized epithelial cells.
A polarized epithelial culture system and chlamydia-specific T-cell lines and clones were employed to investigate the ability and mechanisms by which T cells control the growth of chlamydiae in epithelial cells. Monolayers of polarized mouse epithelial cells were infected with the Chlamydia trachomatis agent of mouse pneumonitis (MoPn) and then exposed to an
