In order to improve the measurement performance of the seven-electrode conductivity sensor, this study focuses on the influence of the electrode spacing on the electric field distribution, current density, and polarisation effect, and explores the operating characteristics of the conductivity cell under different voltage electrode spacings through simulation and experimental validation, aiming to ...Show More
Aiming at the problem of insufficient response speed of the marine conductivity sensor, a method of designing a dynamic compensation filter model for dynamic compensation is proposed to improve the response speed of the sensor. The dynamic response curve of the sensor was measured by the marine sensor time constant measurement device, and the dynamic compensation filter model of the conductivity s...Show More
Efficiency is one of the key elements to characterize the performance of inverter-fed permanent magnet synchronous machines (PMSMs). However, it is challenging to establish an efficiency model that accurately characterizes the input-dependent efficiency uncertainty. Therefore, this article proposes to train a novel heteroscedastic Gaussian process regression (HGPR) model for quantifying the input-...Show More
Regular tunnel lining internal damage (TLID) inspection is very crucial for the railroad operation safety. However, traditional manual identification methods using ground penetrating radar (GPR) images suffer from limited accuracy and efficiency. Fortunately, CNN-based automatic inspection methods have the potential to replace manual inspections, offering improved precision and productivity. In th...Show More
Accurate estimation of state of health (SOH) is critical for the safe and efficient operation of lithium-ion batteries in electric transport tools. However, the random charge/discharge behaviors complicate online SOH estimation and discount estimation accuracy. To overcome this difficulty, this study presents an ensemble learning and voltage reconstruction-based SOH estimation framework through th...Show More
Accurate estimation of state of charge (SOC) is crucial for operation performance promotion of lithium-ion batteries. However, the variations of temperature and loading current directly impact the estimation accuracy of SOC. To fully account for these influences, this study proposes a hybrid compensation model and exploits an advanced algorithm for high-performance SOC estimation. First, a fractio...Show More
This study aims at investigating drivers’ risk perception ability. To achieve this objective, the risk sensitivity and risk judgment thresholds of drivers of different ages were calculated. Five scenarios of intersections with risks were established for the driving simulator experiment. The driving behavior data of fourteen younger drivers and fourteen elderly drivers during the risky event and th...Show More
