The body force in a three-dimensional Lame' system: identification and regularization

Dang Duc Trong, Phan Thanh Nam, Phung Trong Thuc

Let a three-dimensional isotropic elastic body be described by the Lamé system with the body force of the form $F (x, t) = ϕ (t) f (x)$ , where $ϕ$ is known. We consider the problem of det…

Determine the spacial term of a two-dimensional heat source

Dang Duc Trong, Alain Pham Ngoc Dinh, Phan Thanh Nam

We consider the problem of determining a pair of functions $(u, f)$ satisfying the heat equation $u_{t} - Δ u = φ (t) f (x, y)$ , where $(x, y) \in Ω = (0, 1) \times (0, 1)$ and the function $φ$ is…

Ice formation in the Arctic during summer: false-bottoms

Phan Thanh Nam, Alain Pham Ngoc Dinh, Pham Hoang Quan +1

The only source of ice formation in the Arctic during summer is a layer of ice called false-bottoms between an under-ice melt pond and the underlying ocean. Of interest is to give…
