The traditional correlation-based detector is optimal only for Gaussian data, but the Laplacian Probability Density Function (PDF) is more appropriate to model the coefficients in the Discrete Ridgelet Transform (DRT)...

The circular clique number of a graph G is the maximum fractional k/d suchthat G_d^k admits a homomorphism to G. In this paper, we give some sufficient conditions for graphswhose circular clique number equal the cliqu...

An r-circular coloring of a graph G is a map f from V(G) to the set of open unit intervals of an Euclidean circle of length r, such that f(u) ∩ f(v) = Ф whenever uv ∈ E(G). Circular perfect graphs are defined analo...
