Parabolic partial differential equations (PDEs) are fundamental in modelling a wide range of diffusion processes in physics, finance and engineering. The numerical ...

In this paper, we investigate the use of ultra weak variational formulation to solve a wave scattering problem in near field optics. In order to capture the sub-scale features of waves, we utilize ...

Due to the chaotic nature of the atmosphere, weather forecasts, even with ever improving numerical weather prediction models, eventually lose all skill ...

The inverse chirp z-transform (ICZT) can be used with chirp contours that perform partial or multiple revolutions on the unit circle, according to engineers at Iowa State University. Last year, Iowa ...
