A specimen MPI application: N-Queens in parallel
: The generalized problem of placing n queens on an n-by-n board provides an "embarrassingly parallel" problem for parallel solution. This paper expands on the discussion...

Norm invariant discretization for sampled-data fault detection
In this paper, the problem of fault detection in sampled-data systems is studied. It is shown that norms of a sampled system are equal to the corresponding norms of a certain disc...

Visibility Computations: From Discrete Algorithms to Real Algebraic Geometry
We investigate visibility computations with moving viewpoints. The initial problems are of discrete and algorithmic nature, but even for simple classes of objects (such as balls an...
