| 1 | Fast-moving target tracking based on mean shift and frame-difference methods显示文摘The mean shift tracker has difficulty in tracking fast moving targets and suffers from tracking error accumulation problem.To overcome the limitations of the mean shift method,a new approach is proposed by integrating the mean shift algorithm and frame-difference methods.The rough position of the moving target is first located by the direct frame-difference algorithm and three-frame-difference algorithm for the immobile camera scenes and mobile camera scenes,respectively.Then,the mean shift algorithm is used to achieve precise tracking of the target.Several tracking experiments show that the proposed method can effectively track first moving targets and overcome the tracking error accumulation problem. | Hongpeng Yin Yi Chai Simon X.

| 5 | A Novel Rolling Bearing Vibration Impulsive Signals Detection Approach Based on Dictionary Learning显示文摘The localized faults of rolling bearings can be diagnosed by its vibration impulsive signals.However,it is always a challenge to extract the impulsive feature under background noise and non-stationary conditions.This paper investigates impulsive signals detection of a single-point defect rolling bearing and presents a novel data-driven detection approach based on dictionary learning.To overcome the effects harmonic and noise components,we propose an autoregressive-minimum entropy deconvolution model to separate harmonic and deconvolve the effect of the transmission path.To address the shortcomings of conventional sparse representation under the changeable operation environment,we propose an approach that combines K-clustering with singular value decomposition(K-SVD)and split-Bregman to extract impulsive components precisely.Via experiments on synthetic signals and real run-to-failure signals,the excellent performance for different impulsive signals detection verifies the effectiveness and robustness of the proposed approach.Meanwhile,a comparison with the state-of-the-art methods is illustrated,which shows that the proposed approach can provide more accurate detected impulsive signals. | Chuan Sun Hongpeng Yin Yanxia Li Yi Chai | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，6： | 1 |
| 6 | A Novel Product Remaining Useful Life Prediction Approach Considering Fault Effects显示文摘In this paper,a novel remaining useful life prediction approach considering fault effects is proposed.The Wiener process is used to construct the degradation process of single performance characteristic with the fault effects.The first passage time based remaining useful life distribution is calculated by assuming fault occurrence moment is a random variable and follows a certain distribution.Expectation maximization algorithm is employed to estimate model parameters,where the fault occurrence moment is considered as a missing data.Finally,a Copula function is used to describe the dependence between the multiple performance characteristics and derive joint remaining useful life(RUL)distribution of product with the fault effects.The effectiveness of the proposed approach is verified by the experiments of turbofan engines. | Jingdong Lin Zheng Lin Guobo Liao Hongpeng Yin | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，11： | 0 |
| 7 | Parameter optimization and experiment of the negative pressure precision seed-metering device for wheat显示文摘In order to ensure the most reasonable distribution of wheat seeds in the field to improve seeding quality and uniformity,a set of negative pressure precision seed-metering device was designed,which shares a hollow shaft.Every seed-metering device can sow two rows of wheat.By the STAR-CCM+,the analysis of nephogram,vectogram and streamline graph showed that more ideal structural parameters of the seed-metering device are 0.5 mm width of the slit sucking seed(WSS),150-200 mm diameter of the seed-metering disc(DSD),2.0 mm axial depth of air chamber in the seed-metering disc(ADS),and arc-shaped cross-section shape of the ring groove sucking seed(CSGS).Single-factor test on the JPS-12 test-bed analyzed the influence of the CSGS,WSS,DSD,and ADS on the qualified index(Iq),multiple index(Imul),miss index(Imiss)and coefficient of variation of qualified seed spacing(CV).Through the orthogonal on the JPS-12 test-bed,it is found that the influence of vacuum negative pressure and seed-metering device shaft speed is significant on the Iq,Imiss and Imul.Based on these,the structural parameters of the seed-metering device were optimized.The DSD is 180 mm,the WSS is 0.7 mm,the ADS is 2.5 mm,and the CSGS is arc-shaped.The optimization seed-metering device was tested on the JPS-12 test-bed.The Iq is 86.66%,the Imiss is 5.09%,the Imul is 8.25%,and the CV is 24.50%.These testing results fully coincide with the standard JB/T 10293-2013 Specifications of single seed drill(precision drill).The seed-metering device meets fully the requirements for wheat precision seeding. | Yubo Feng Xiaoshun Zhao Jincai Li Huali Yu Hongpeng Zhao Baozhong Yin | 2024 | International Journal of Agricultural and Biological Engineering2024，17，1： | 0 |
| 8 | Mechanisms of Myocardial Stunning in Stress-Induced Cardiomyopathy显示文摘Stress-induced cardiomyopathy,in contrast to acute myocardial infarction,is a type of acute heart failure characterized by reversible left ventricular dysfunction.Cardiac imaging primarily reveals left ventricle myocardial stunning,81.7%of which is apical type.Emotional or psychological stress usually precedes the onset of stress-induced cardiomyopathy,which is increasingly being recognized as a unique neurogenic myocardial stunning disease.To distinguish between acute myocardial infarction and acute viral or auto-immune myocarditis,this review summarizes specific mechanisms of myocardial stunning in stress-induced cardiomyopathy,such as calcium disorders,metabolic alterations,anatomical and histological variations in different parts of the left ventricle,and microvascular dysfunction. | Quanwei Pei Nadine Mbabazi Lina Zou Junpei Zhang Hongpeng Yin Bin Li Jiaxin Wang Weifa Wang Pengqi Lin Junjie Yang Dechun Yin | 2022 | Cardiovascular Innovations and Applications2022，7，3： | 0 |
| 9 | Role of Epicardial Adipose Tissue in Triggering and Maintaining Atrial Fibrillation显示文摘Atrial fibrillation is the most common arrhythmia leading to cardiogenic stroke.Without membranous sructure between epicardial adipose tissue and atrial myocardium,epicardial adipose tissue directly covers the surface of the atrial myocardium.The formation of an epicardial adipose tissue inflammatory microenvironment,fibrosis,infiltration by epicardial adipose tissue,autonomic dysfunction and oxidative stress are important mechanisms that trigger and maintain atrial fibrillation.Those mechanisms are reviewed herein. | Weifa Wang Yanfeng Tian Wei Wang Hongpeng Yin Dechun Yin Ye Tian | 2022 | Cardiovascular Innovations and Applications2022，7，3： | 0 |
| 10 | The Role of Sleep Deprivation in Arrhythmias显示文摘Sleep is essential to the normal psychological and physiological activities of the human body.Increasing evidence indicates that sleep deprivation is associated with the occurrence,development,and poor treatment effects of various arrhythmias.Sleep deprivation affects not only the peripheral nervous system but also the central nervous system,which regulates the occurrence of arrhythmias.In addition,sleep deprivation is associated with apoptotic pathways,mitochondrial energy metabolism disorders,and immune system dysfunction.Although studies increasingly suggest that pathological sleep patterns are associated with various atrial and ventricular arrhythmias,further research is needed to identify specific mechanisms and recommend therapeutic interventions.This review summarizes the findings of sleep deprivation in animal experiments and clinical studies,current challenges,and future research directions in the field of arrhythmias. | Wenlong Wang Hongpeng Yin Ge Sun Junpei Zhang Jingmei Sun Nadine Mbabazi Lina Zou Bin Li Pengqi Lin Quanwei Pei Xin Wang Penghe Wang Xuanrui Ji Xiufen Qu Dechun Yin | 2022 | Cardiovascular Innovations and Applications2022，7，3： | 0 |
| 11 | Termination of Recurrent Atrial Fibrillation by Superior Vena Cava Isolation: A Case Report显示文摘Background:Paroxysmal atrial fibrillation can be triggered by non-pulmonary vein foci,such as the superior vena cava.Here,we report the case of a patient with a 6-year history of paroxysmal atrial fibrillation who received cryoballoon ablation in 2012 but relapsed in 2014.He then received cardiac radiofrequency ablation,which successfully isolated the left pulmonary vein and superior vena cava,but the arrhythmia recently relapsed again.The tachycardia was finally successfully terminated by ablation on the free wall without recurrence during a 2-year following up.Conclusion:Superior vena cava isolation may not require ablation isolation with a full circle way and can be accomplished by ablating several connection points between the superior vena cava and the right atrium. | Hongpeng Yin Wenlong Wang Bin Li Xiufen Qu Shaojun Wang Dechun Yin | 2022 | Cardiovascular Innovations and Applications2022，7，3： | 0 |
| 12 | Enabling rechargeable Li-MnO_(2) batteries using ether electrolytes显示文摘A low-carbon future demands more affordable batteries utilizing abundant elements with sustainable end-of-life battery management.Despite the economic and environmental advantages of Li-MnO_(2)batteries,their applica-tion so far has been largely constrained to primary batteries.Here,we demonstrate that one of the major limiting factors preventing the stable cycling of Li-MnO_(2)batteries,Mn dissolution,can be effectively mitigated by employing a common ether electrolyte,1 mol/L lithium bis(trifluorometha-nesulfonyl)imide(LiTFSI)in 1,3-dioxane(DOL)/1,2-dimethoxyethane(DME).We discover that the suppression of this dissolution enables highly reversible cycling of the MnO_(2)cathode regardless of the synthesized phase and morphology.Moreover,we find that both the LiPF_(6)salt and carbonate solvents present in conventional electrolytes are responsible for previous cycling challenges.The ether electrolyte,paired with MnO_(2)cathodes is able to demonstrate stable cycling performance at various rates,even at elevated temperature such as 60℃.Our discovery not only represents a defining step in Li-MnO_(2)batteries with extended life but provides design criteria of electrolytes for vast manganese-based cathodes in rechargeable batteries. | Dawei Xia Hongpeng Gao Mingqian Li John Holoubek Qizhang Yan Yijie Yin Panpan Xu Zheng Chen | 2023 | SmartMat2023，4，5： | 0 |
