The authors describe their work on the massively parallel finite-element computation of compressible and incompressible flows with CM-200 CM-5 Connection Machines. Their computations are based implicit methods, implementations assumption that mesh is unstructured. Computations for flow problems involving moving boundaries interfaces achieved by using deformable-spatial-domain/stabilized-space-time method. Using special update schemes, frequency remeshing minimized to reduce projection errors...
Motivated by increasing the packet efficiency of pilot-based wireless communication, we derive accurate expressions channel-estimation minimal mean square error (MMSE) for finite blocklength communication over continuous fading. We used time vectorial representation and quantified dependence MMSE expression on various system parameters interest (e.g., size, fading rate, signal-to-noise ratio). It is shown that using conventional infinite-blocklength substantially undervalues channel...

Abstract Streamline‐upwind/Petrov–Galerkin finite element method is developed for buoyancy‐driven incom‐pressible flows with heat and mass transfer. The stabilized formulations are implemented in parallel using message passing interface libraries. To measure the accuracy of method, we solve a 2D numerical example natural convection at moderate to high Rayleigh numbers. 3D applications include dispersion smoke from chimney within stadium.

In this paper we will present a new computational approach to simulate free-surface flow problems efficiently. The finite element solution strategy is based on combination derived from fixed-mesh and moving-mesh techniques. Here, the simulations are Navier-Stokes equations written for two incompressible fluids where impact of one fluid other extremely small. An interface function with distinct values used locate position in regions near floating object, while mesh-moving move wave breaking...
