The three doweled pieces of this unpainted wooden model can be arranged either as a rectangle or as an obtuse-angled triangle. Compare models 1985.0112.190 through 1985.0112.202.

In many classification scenarios, the data to be analyzed can be naturally represented as points living on the curved Riemannian manifold of symmetric positive-definite (SPD) matrices. Due to its ...

In this paper, new techniques are presented to either simplify or improve most existing upper bounds on the maximum-likelihood (ML) decoding performance of the binary linear codes over additive white ...
