Accurate Boundary Conditions for Twin Boundary
Communications in Computational Physics, 2021In this paper a heterogeneous lattice with twin boundary is considered. The authors develop some accurate boundary conditions for treating the numerical boundary in the problem under consideration. These conditions include time history kernel (THK) treatment and matching boundary conditions (MBC).

Learning with Boundary Conditions
Neural Computation, 2013Kernel machines traditionally arise from an elegant formulation based on measuring the smoothness of the admissible solutions by the norm in the reproducing kernel Hilbert space (RKHS) generated by the chosen kernel. It was pointed out that they can be formulated in a related functional framework, in which the Green’s function of suitable differential

THE ‘NO BOUNDARY CONDITION’ OUTFLOW BOUNDARY CONDITION
International Journal for Numerical Methods in Fluids, 1997Summary: We use a one-dimensional model problem of advection-diffusion to investigate the treatment recently advocated by \textit{T. C. Papanastasiou, N. Malamataris} and \textit{K. Ellwood} [Int. J. Numer. Methods Fluids 14, No. 5, 587--608 (1992; Zbl 0747.76039)] to deal with boundary conditions at artificial outflow boundaries. Using finite elements

Generalized Boundary Conditions
The Physics of Fluids, 1970The concept of the generalized boundary condition is introduced, and stabilization of ion-sound waves and drift waves using such boundary conditions is demonstrated. The boundary consists of a two-dimensional, lumped-parameter transmission line in electrical contact with the plasma.

Chapter 2 extends the ideas presented in the previous chapter by situating a whole range of self-narratives on a spectrum involving more or less fully imagined forms of relationality between humans and other animals. With chapter 1 having provided a detailed reading of two particular case studies, chapter 2 uses a variety of texts—including memoirs and

Abstract The actual dynamics of fluid flows is highly dependent on the surrounding environment. This influence is described mathematically via the prescription of suitable boundary conditions. Boundary conditions play a crucial role since they select solutions which are compatible with external constraints.
