Recovering the spatiotemporally dependent diffusion and advection coefficients in a pathway-based Keller--Segel model
Yu'an Li, Lingyun Qiu, Min Tang +3
We investigate an inverse coefficient problem for an augmented Keller--Segel model arising in the description of phototactic and chemotactic population dynamics. The spatiotemporal…
An Acoustic Inversion-Based Flow Measurement Model in 3D Hydrodynamic Systems
Jiwei Li, Lingyun Qiu, Zhongjing Wang +1
This study extends the flow measurement method initially proposed in [22] to three-dimensional scenarios, addressing the growing need for accurate and efficient non-contact flow me…
Sediment Concentration Estimation via Multiscale Inverse Problem and Stochastic Homogenization
Jiwei Li, Lingyun Qiu, Zhongjing Wang +2
We develop a multiscale framework for estimating sediment concentration in water flow from acoustic wave measurements. At the microscopic scale, the sediment distribution is modele…
Traceability of Water Pollution: An Inversion Scheme Via Dynamic Complex Geometrical Optics Solutions
Lingyun Qiu, Zhongjing Wang, Hui Yu +1
We investigate the identification of the time-dependent source term in the diffusion equation using boundary measurements. This facilitates tracing back the origins of environmenta…
Flow Measurement: An Inverse Problem Formulation
Jiwei Li, Lingyun Qiu, Zhongjing Wang +1
This paper proposes a new mathematical formulation for flow measurement based on the inverse source problem for wave equations with partial boundary measurement. Inspired by the de…
