1. Use of remote control in the intraoperative telemetry of cochlear implant: multicentric study
Resumo Introdução: A avaliação convencional da telemetria neural e de impedâncias implica o uso do computador acoplado a uma interface, o software fornece o estímulo e a visualização das respostas. Recentemente, foi lançado um controle remoto (CR220®), que possibilita testes intraoperatórios com instrumental mínimo. Objetivo: Avaliar a concord�

2. Simulador didático para análise dos transientes de ondas de tensão em uma linha de transmissão similar à transmissão e reflexão de ondas eletromagnéticas
Abstract O modelo de educação nas últimas décadas passou por mudanças consideráveis do ponto de vista didático. Com o avanço da tecnologia, a velocidade de obtenção de informações aumenta e o uso de ferramentas que permitem a visualização dinâmica de conteúdos torna-se um forte aliado ao processo de ensino-aprendizagem. Este trabalho trata da

3. Numerical fundamentals and interactive computer graphics system for the nonlinear analysis of planar frames
Abstract Recent scientific and computational advances have facilitated the analysis of slender structural systems subject to instability. With the employment of more sophisticated numerical tools and algorithms, it is possible to accurately determine the critical points (limit and bifurcation loads) as well as the post-critical behavior of the structural sys

4. Diseño y Evaluación de una Trayectoria Hipotética de Aprendizaje para Intervalos de Confianza basada en Simulación y Datos Reales
Abstract This article discusses the design of a hypothetical learning trajectory to introduce the confidence intervals in a basic university course, from an informal perspective based on the use of data obtained from surveys and samples simulation. The trajectory consists of four activities and was evaluated as part of a first improvement cycle with a group

5. Efficacy Analysis of a Script-based Guide for EVAR Execution: is it Possible to Reduce Patient Exposure to Contrast, Operative Time and Blood Loss even when Advanced Technologies are not Available?
ABSTRACT INTRODUCTION: Despite the patient and medical staff exposure to radiation in endovascular aneurysm repair, the benefits of this abdominal aortic aneurysm type of surgical management are justfied by minor recovery time and hospitalization, as well as an option for patients not elected to conventional open repair. In this minimally invasive surgical

6. Visualização exploratória de dados volumétricos multivalorados variantes no tempo / Exploratory visualization of volumetric data multivalued time varying
Simulações por computador permitem reduzir custo e, muitas vezes, realizar experimentos que na vida real seriam impraticáveis, ou por questões ambientais (explosões nucleares), ou por fatores que estão fora do controle do ser humano (colisões entre estrelas). Entretanto, e muito difícil manipular e analisar as centenas de gigabytes, ou mesmo terabyte

7. Aprimoramento do algoritmo PQR-Sort para reordenação de matrizes binárias / Improved of PQR-Sort algorithm for binary matrices reordering
Algoritmos de reordenação são importantes para analise de dados matriciais, pois encontram automaticamente permutações de linhas e colunas que agrupam valores semelhantes em uma matriz, visando facilitar a busca visual por padrões e tendências nos dados. Alem disso, esses algoritmos tendem a reduzir a sobrecarga cognitiva do usuário, tendo em vista q

8. Determination of the Representative Elementary Volume for the study of sandstones and siltstones by X-Ray microtomography
X-Ray computerized microtomography (µ-CT) besides providing two-dimensional images (2-D) of the transversal sections of the sample, the biggest attraction of the methodology is the rendering of three-dimensional images (3-D), enabling a more real analysis of the porous structure of the rock. However, the reconstruction, visualization and analysis of such 3-

9. New tools for epidemiology: a space odyssey
Geographical Information Systems (GIS) facilitate access to epidemiological data through visualization and may be consulted for the development of mathematical models and analysis by spatial statistics. Variables such as land-cover, land-use, elevations, surface temperatures, rainfall etc. emanating from earth-observing satellites, complement GIS as this inf

10. Three-dimensional characterization of pores in Ti-6Al-4V alloy
The direct three-dimensional characterization of opaque materials through serial sectioning makes possible to visualize and better quantify a material microstructure, using classical metallographic techniques coupled with computer-aided reconstruction. Titanium alloys are used as biomaterials for bone implants because of its excellent mechanical properties,
