In this paper, we propose a new path planning algorithm based on the probabilistic roadmaps method (PRM), in order to effectively solve the autonomous path planning of mobile robots in complex environments with multiple narrow channels.The improved PRM algorithm mainly improves the density and distribution of sampling points in the narrow channel,
This study presents a simulation-based investigation into the application of a Cascade Proportional-Integral-Derivative (PID) combined with Linear Quadratic Regulator (LQR) control scheme for managing the complexities of a Nonlinear Flexible Inverted Pendulum System (NFIPS).The NFIPS, characterized by nonlinear dynamics and structural flexibility,
The COVID-19 pandemic has provided stiff challenges for planning and resourcing in health services in the UK and worldwide.Epidemiological models can provide simulations of how infectious disease might progress in a population given certain parameters.We adapted an agent-based model of COVID-19 to inform planning and decision-making within a health
The [Paris polyphylla Smith var.Yunnanensis (Franch.)
