An effective integrated-RBFN Cartesian-grid discretization for the stream function-vorticity-temperature formulation in nonrectangular domains [PDF]
This paper presents a new numerical collocation procedure, based on Cartesian grids and one-dimensional integrated radial-basis-function networks (1D-IRBFNs), for the simulation of natural convection defined in two-dimensional multiply-connected domains ...

Embedding Features in a Cartesian Grid
Grid-based mesh generation methods have been available for many years and can provide a reliable method for meshing arbitrary geometries with hexahedral elements. The principal use for these methods has mostly been limited to biological-type models where topology that may incorporate sharp edges and curve definitions are not critical.

On NUFFT-based gridding for non-Cartesian MRI [PDF]
For MRI with non-Cartesian sampling, the conventional approach to reconstructing images is to use the gridding method with a Kaiser-Bessel (KB) interpolation kernel. Recently, Sha et al. [L. Sha, H. Guo, A.W. Song, An improved gridding method for spiral MRI using nonuniform fast Fourier transform, J. Magn. Reson.

Euler Solution Using Adaptive Cartesian Grid With A Gridless Boundary Treatment
A quadtree-based adaptive Cartesian grid generator and flow solver were developed. The grid adaptation based on pressure or density gradient was performed and a gridless method based on the least-square fashion was used to treat the wall surface boundary

A simple Cartesian scheme for compressible multimaterials [PDF]
We present a simple numerical method to simulate the interaction of two non-miscible compressible materials separated by an interface. The media considered may have significantly different physical properties and constitutive laws, describing for example

Conditions for isonemal arrays on a Cartesian grid
AbstractThe concept of an isonemal binary array on a Cartesian grid is examined, and rules for constructing all such arrays are identified. Examples are included for the various possible constructions, and tables of compound twillins of periods six and eight are given.

The numerical treatment of curved boundary surfaces in an unfitted grid formulation for computational fluid dynamics [PDF]
In this thesis a new Cartesian cut-cell scheme has been presented which solves the in- compressible Navier-Stokes equations using a finite volume approach and a staggered grid.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
