1. ESTIMATION OF PARAMETERS AND STATES USING A BAYESIAN PARTICLE FILTER FOR THE SULFATE ION ADSORPTION PROCESS IN A FIXED BED COLUMN
Abstract Ensuring that industrial effluents meet quality standards to be released into water bodies is still one of the major environmental concerns. Liquid phase adsoption in fixed bed collumns is one of the most known treatments. Measurements are needed to monitor the process. However, as they are often corrupted by noise from the measuring equipment, perf

2. INNOVATION SYSTEM IN AIR TRANSPORT MANAGEMENT
Abstract Identifying previous research subjects on innovation management in air transport provides not only updated references on new technologies in this industry, but also indicates which areas need to be prioritized in future research. A systematic literature review of publications in this field over the past decade, from 2005 to 2015, including 2016 publ

3. Percepção de risco no uso do equipamento de proteção individual contra a perda auditiva induzida por ruído
Resumo Embora existam muitas abordagens sobre a exposição ocupacional ao ruído, a análise da percepção individual do trabalhador e suas implicações sobre o seu comportamento constituem ainda um tema raramente abordado. Objetivando colaborar em minimizar esta lacuna, fez-se um levantamento do estado da arte das publicações que relacionam às vari�

4. Evaluation of the Residual Stress State of 42crmo4 Steel Sheets in a Production Line
The residual stress state of a mechanical component is an important factor in its production planning and in estimates of its lifecycle since it can be responsible for geometric distortions and degradation of fatigue properties. Therefore, the development of reliable methods for non-destructively quantifying these stresses remains in the interest of most man

5. Noise Source Distribution of Coaxial Subsonic Jet-Short-Cowl Nozzle
ABSTRACT: The noise source distribution of a short-cowl coaxial jet operating at different velocity ratios is described in this work. This was motivated by an ongoing research about noise prediction of coaxial jets through Acoustic Analogy with purposes of industrial engine application. This research has been carried out between Universidade Federal de Uberl

6. Controle ativo de ruído aplicado a dutos com propagação de modos acústicos de alta ordem via particionamento axial / Active noise control applied to ducts with propagation of high- order acoustic modes via partitioning axial
O controle ativo de ruído (CAR) aplicado a dutos onde existe a propagação de ondas planas tem sido alvo de vários estudos. Aplica-se, nesses casos, o controle ativo monocanal. Nos dutos com grandes seções transversais, a propagação acústica se dá com a presença dos modos de alta ordem. Nesses dutos é necessário o controle multicanal, o que leva

7. A wavelet-based approach for analyzing industrial stochastic textures with applications
Several continuous manufacturing processes use stochastic texture images for quality control and monitoring. Large amounts of pictorial data are acquired, providing important information about both the materials produced and the manufacturing processes involved. However, it is often difficult to measure objectively the similarity among industrial stochastic

9. Uma Metodologia para a Avaliação Virtual da Dose de Exposição ao Ruído no Ambiente de Trabalho / A Methodology for Virtual Evaluating Noise Dose Exposure in the Workplace
A permanência de pessoas em ambientes com níveis de ruído elevados pode causar comprometimentos orgânicos diversos, como hipertensão arterial, estresse, aumento da tensão muscular, incapacidade de concentração além de distúrbios auditivos temporários e permanentes. A perda auditiva induzida pelo ruído ocupacional (PAIRO) é a única patologia cau
