Abstract Background It has been suggested that extended high‐frequency audiometry (EHFA) might be more sensitive than conventional in detecting early signs of hearing impairment. However, this technique not adequately tested an occupational environment. We therefore investigated the usefulness method noise‐exposed workers. Methods compared frequency (0.25–8 kHz) and EHFA (9–18 184 98 non‐noise‐exposed Results Both methods showed significantly higher threshold levels (P < 0.05) workers for...
This article reports on the creation of an open database piezo-actuated and piezo-received guided wave signals propagating in a composite panel full-scale aeronautical structure. The closes bottom part wingbox that, along with leading edge, trailing wingtip, forms outer wing demonstrator approximately 4.5 m long from 1.2 to 2.3 wide. To create database, structural health monitoring system, composed software/hardware central unit capable controlling network 160 piezoelectric transducers...
This work presents a full three-dimensional finite-element multiphysics simulation of the conjugate heat transfer for gas sensing device composed by two-element array ultra low power (ULP) metal oxide semiconductor (MOX) sensors operated in miniaturized sampling chamber. The equation solid, Poisson electric potential and incompressible Navier-Stokes energy equations fluid have been solved coupled manner. Validation results has performed comparing simulated dissipated with set experimental...
Acoustic Emissions (AE) are at the basis of extremely accurate and reliable monitoring systems. Within SmartBench project, data regarding structural health components gathered in a database order to make safety integrated, operative smart. An modelling wave propagation is necessary requirement for proper design sensor networks as well interpretation. Numerical simulations transient behavior systems well-established this field but, on minus side, they very expensive terms computational time...
The aim of this paper is to present an acquisition system and experimental measurements a new micromachined Thermal Conductivity Detector (μTCD), applied downstream gas-chromatography (GC) system. We describe simple innovative electronics for sensor control data acquisition, outlining its resistance control, native imbalance compensation automatic gain (AGC) algorithm. Measurements sensitivity tests have been carried out by connecting our TCD the microfluidic section GC column commercial...

This paper discusses the objectives and early results of project PROAGE, funded by INAIL under Safara framework. The aim is to better control ageing equipment, quantify impact operating modes on system reliability, estimate their residual life adapt maintenance strategy, while respecting safety, regulation operational performance. Monitored systems in modern process plants can be seen as intelligent prognostics measure, control, alert personnel, detecting degradation mechanisms (such fatigue...
Structural Health Monitoring (SHM) systems based on ultrasonic guided waves and sensors permanently installed structures have the potential to decrease maintenance costs reduce risk of failures critical components in a chemical plant. Such systems, fact, can check health status structure, prompting interventions only when needed not at prescribed intervals. Moreover, they be used real time basis or activated remote for extemporary checks. The monitoring process consists two main steps: (i)...
