Abstract: In this article, an inexpensive beam homogenizer is designed to transform the laser beam with irregular intensity into a uniform square beam with a large size, thus eliminating the ...

This is a finite volume (toy) toolbox for chemical/petroleum engineers. Right now, it can solve a transient convection-diffusion equation with variable velocity field/diffusion coefficients. The ...

Abstract: This letter shows that the description of signal sampling operation that uses a weighted Dirac comb plays only a supporting role. It must be supplemented with a relation that transfers this ...
