A ghost-cell immersed boundary method for the shallow water equations on Cartesian grids: mass conservation and wetting and drying over variable topography
Yuta Yaegashi
A ghost-cell immersed boundary method is proposed for the two-dimensional shallow water equations with a variable bed (topography), solved with an explicit Godunov-type finite volu…
Analytical and numerical solutions to ergodic control problems arising in environmental management
Hidekazu Yoshioka, Motoh Tsujimura, Yuta Yaegashi
Environmental management optimizing a long-run objective is an ergodic control problem whose resolution can be achieved by solving an associated non-local Hamilton-Jacobi-Bellman (…
Stochastic impulse control of non-smooth dynamics with partial observation and execution delay: application to an environmental restoration problem
Hidekazu Yoshioka, Yuta Yaegashi
Non-smooth dynamics driven by stochastic disturbance arise in a wide variety of engineering problems. Impulsive interventions are often employed to control stochastic systems; howe…
A random observation-based management model of population dynamics and its ecological application
Hidekazu Yoshioka, Yuta Yaegashi, Motoh Tsujimura
A new stochastic control problem of population dynamics under partial observation is formulated and analyzed both mathematically and numerically, with an emphasis on environmental…
