Polynomial identity testing (PIT) problem is known to be challenging even for constant depth arithmetic circuits. In this work, we study the complexity of two special but natural ...
tion problem in two steps. First, we formulate an abstract optimization problem for video streaming in wireless networks in general. This formulation exposes the important interact...
We construct a new mimetic tensor artificial viscosity on general polyhedral meshes. The tensor viscosity is designed as a discretization of the differential operator div (u) with...
The goal of this note is to generalize the topological gradient method, applied to restoration and classification problems for grey-level images, to color images. We illustrate ou...
General signal model for orthogonal-frequency-division multiple access cellular networks with multiple amplify-and-forward relays has been introduced. An optimization problem mini...
