Performance Characteristics of Newly Developed Real-Time Wave Measurement Buoy Using the Variometric Approach
Published 2024-11-01“…However, wave mean period disparities were observed partially because of sampling frequency differences. To validate this idea, we used Joint North Sea Wave Project (Jonswap) spectral waves as input signals, the bias characteristics of the mean periods of the spectral calculations were compared under conditions of identical input signals and gradient-distributed wind speeds. …”

Lived experiences of farmworkers from five U. S. states during the COVID-19 pandemic
Published 2025-06-01“…ObjectiveThe nexus of farmworker and COVID-19 peer-reviewed research has yet to be advanced by qualitative analysis that: (1) focuses on multiple dimensions of farmworker’s daily life and (2) uses a geographically diverse sample. The present data collection project fills this gap by using the National Center for Farmworker Health’s (NCFH) Farmworker COVID-19 Community Assessment (FCCA) Phase 2 dataset which contains a varied sample of farmworkers and local experts across selected counties in five states. …”

Efficient 3D imaging method of MIMO radar for moving target
Published 2019-07-01“…When compressive sensing (CS) was used to achieve sparse imaging of moving targets,the Doppler frequency caused by motion will increase the processing dimension,change the center frequency of echo and worsen the mutual coherence property of measurement matrix.In order to improve the three-dimensional (3D) imaging performance of MIMO radar for moving targets,an efficient method was proposed.In each dimension,the distribution information of targets was searched respectively and a new low-dimensional measurement matrix was reconstructed accordingly,so the targets’ area was narrowed down.At the same time,in order to optimize the mutual coherence property of measurement matrix,Bayesian method was used to optimize the velocity-dimensional projection matrix to reduce the strong mutual coherence brought by sampling of Doppler frequency,then the efficient sparse imaging could be achieved.The simulation results show that proposed method can improve the efficiency,accurate imaging performance with efficient.…”

渐开线塑料齿轮齿廓偏差影像法测量的不确定度和抽样检验统计特性
Published 2012-01-01“…Applying projection method,the involute plastic gear tooth profile deviation is measured.As plastic gear tooth profile is much influenced by mechanical stress and thermal stress in machining,thus causing more tooth profile strain,to reflect precisely the measuring result of plastic gear tooth profile deviation,and confirm the precision level of it,the rotation bias error,rotation division error,aiming indication error and repeating measuring error are appraised by A series uncertainty and B series uncertainty.Trough analysis by the statistic range controlling chart,a same conclusion is reached.Combining single tooth profile deviation measurement with random sampling inspection,the accuracy grade of plastic gear tooth profile deviation is confirmed,which is out of the national standard range of gear tooth profile accuracy grade.Thus,the tested plastic gear by machining is more used in display in laboratory than in industry.…”
