Abstract Purpose To examine the effect of diabetes, duration and blood glucose on speech-, low/mid-, high-frequency hearing loss. Methods In this cross-sectional study, 2821 participants aged 20–87 years in China National Health Survey were included. Diabetes was defined as valid fasting (FBG) ≥ 7.0 mmol/L, a self-reported history diabetes or use anti-diabetic medications. Speech-(500, 1000, 2000, 4000 Hz), low/mid- (500, 1000 2000 (4000, 6000, 8000 Hz) loss pure tone average responding...
The impact of land use changes caused by urban sprawl on water quality since the 1970s in northern Georgia, USA is studied examining spatial and temporal relationships between indicators 43 watersheds through geographic information system (GIS) statistical analyses. GIS analyses are used to delineate using Digital Elevation Models for sampling sites derive such as land, forest, agricultural wetland each watershed. Statistical examine, quantify, compare find good predictors response...
Small-diameter stainless steel pipes find widespread application in nuclear power systems. In order to detect surface axial wear defects that may occur during their service life, a circular fully enclosed probe has been developed for inspecting these small-diameter pipes. The is composed of periodic permanent magnet (PPM) and racetrack-shaped coil. Through the optimised design PPM structure, two probes were devised excite single flexural torsional modes, respectively. Furthermore, employing...
To address the challenges of automatic detection caused by variation surface normal vectors in automotive steering knuckles, an method based on ultrasonic phased array technology is herein proposed. First, a point cloud model workpiece was constructed using distance measurement, and Gaussian-weighted principal component analysis used to estimate cloud. By utilizing vectors, water layer thickness during detection, incident angle sound beam, probe pose information corresponding precisely...
Aluminum/rigid polyurethane foam composite plates (ARCPs) are widely used for thermal insulation. The interface debonding generated during manufacturing degrades the insulation performance of an ARCP. In this study, ARCP, a plate with porous and damped layer rigid (RPUF), was detected using A0 mode Lamb wave electromagnetic acoustic transducers (EMATs). low energy transmission coefficient at caused by large impedance difference between aluminum RPUF made detection difficult. Based on these...
This study developed new procedures to loosely integrate an air dispersion model, AERMOD, and a geographic information system (GIS) package, ArcGIS, simulate from stationary sources in the Bronx, New York City, for five pollutants: PM(10), PM(2.5), NO(x), CO, SO(2). Plume buffers created model results were used as proxies of human exposure pollution they modified commonly fixed-distance proximity by considering realities dispersion. The application plume confirmed that higher asthma...
Path planning is a fundamental method in solving mazes or moving robots traversing through open fields with obstacles. Q-learning model-independent reinforcement learning method, which can be utilized path optimization for multi-robot collaboration system. However, the efficiency of traditional algorithm relatively low because adopted random exploration policy. In this paper, Boltzmann Policy based proposed and applied into problem Multi-robot The composed two parts, are grid-based that...
According to the Lenz's Law, eddy-current essentially exists in MFL (magnetic flux leakage) testing due relative movement between steel pipe and excitation coil, apparently affecting signals with speed rising. Hence, co
To further simplify the bolt stress measurement process, feasibility of using a dual-mode electromagnetic acoustic transducer (EMAT) that excites both longitudinal and shear waves is investigated to achieve rapid accurate measurement. The propagation characteristics cylindrical guided in rod are studied by semi-analytical finite element (SAFE) model. Through combination theoretical formula simulation, nonuniform distribution axial directly used calculate time flight without building any...
Periodic permanent magnet(PPM) electromagnetic acoustic transducers (EMATs) are commonly employed for axial defect inspection in pipelines. However, the lowest-order shear horizontal waves (SH0) guided have difficulties distinctly differentiating internal and external defects. To enhance signal-to-noise ratio resolution, a unidirectional transducer (EMAT) based on Circumferential Lamb (CLamb waves) is developed. Through structural parameter optimization excitation frequency adjustment,...
