AN IMPROVED ALGORITHM FOR TIME DOMAIN AVERAGING BASED ON FRACTIONAL DELAY FILTERING
Published 2015-01-01“…For reducing the influence of truncation error on the accuracy of time domain averaging( TDA) induced by noninteger-period sampling,an improved algorithm of TDA based on fractional delay filtering( FDF) is presented.On the basis of analyzing the disadvantages of current methods of TDA and the characteristics of FDF,a presently improved method of signal truncation was used in the method to avoid the accumulation of truncation error and obtain a delay factor on each of the truncated signals,the reconstruction and resample for the truncated signals were implemented with FDF,and finally the arithmetic mean were computed after all of the truncated signals were added.The theoretical analysis and experimental results demonstrate that the method which fully makes using of the advantages of FDF on the change of delay factor,apparently reduces the truncation error of signals with non-integer-period sampling,and could obviously improve the accuracy of TDA without key-phase signal.…”

Thyroid nodule detection and influencing factors in male coal mine workers in Shanxi Province
Published 2025-05-01“…The results of logistic regression showed that the duration of exposure to occupational hazards for 11-20 years, 21-30 years, ≥31 years, average monthly working>26 days, and shift work were positively correlated with the detection of thyroid nodules (P<0.05), and the associated ORs (95%CIs) were 1.29 (1.01, 1.65), 1.55 (1.20, 1.99), 1.68 (1.26, 2.55), 1.19 (1.00, 1.40), and 1.15 (1.02, 1.29), respectively.ConclusionThe duration of exposure to occupational hazards, average monthly working days, and shift work are influencing factors of thyroid nodules. …”

Engagement factors affect academic success through study approaches among physical education and sport university students: a mediation analysis
Published 2025-02-01“…They completed surveys regarding their academic engagement, study approaches, and grade point average (GPA). Analyses of associations were conducted through linear regression analysis and mediation analysis.ResultsResults from the linear regression analysis showed correlations between academic engagement factors, study approach variables, and GPA, with higher GPA correlating with higher scores on behavioral engagement, cognitive engagement, surface theory task, and deep theory task, and with lower scores on surface practical task. …”

Clustering scheme of base stations cooperation based on maximizing the average system performance
Published 2012-11-01“…A novel clustering scheme based on maximizing average system performance was proposed.Firstly,according to the probability distribution of signal-to-interference-ratio (SIR)gain of base stations cooperation the average SIR gains were obtained.Then,the cluster structure was generated in the standard of maximizing the average system performance.Not only the average system performance was guaranteed but also the influence of CSI distortion was decreased,while the overall cost was reduced.Simulation results show that when the factors of CSI distortion and channel vibration both are 0.3,the proposed scheme provide a 0.7bit/s/Hz/cell increase of the average system performance compared with the benefit-tree clustering scheme.…”
