Control of Vehicle Lateral Handling Stability Considering Time-Varying Full-State Constraints
Published 2025-04-01“…To address this issue, this paper proposes a lateral handling stability control method that considers time-varying full-state constraints. By constructing a time-varying symmetric Barrier Lyapunov Function (TS-BLF), this method imposes time-varying nonlinear constraints on both the sideslip angle and yaw rate, thereby ensuring full-state constrained stability control of vehicles under complex operating conditions. …”

Predicting Exposure to Dust Particles Using Spirometric Index and Perception Studies among Farmers in Selected Farm Settlements in Ogun State, Nigeria
Published 2021-02-01“…Abstract The link between agricultural activities and respiratory disease puts farmers at risk of exposure to particulate matter, potentially reducing lung function. Thus, this comparative cross-sectional work employed a spirometric index and perception studies by conducting interviews and on-the-spot lung function tests on 195 farmers living in seven farm settlements of Ogun State and 195 non-farmers living in other areas to assess the ambient levels of the suspended particulate matter and estimate the dust exposure among the first group. …”
