This paper describes the preliminary work of image separation between natural and artificial objects using fractal dimensions by noting that most of natural images have non-intege...
Recently, particular counterexamples were constructed to some theorems of a previous paper, concerning the global attractivity of the positive equilibrium for the delay equation _...
: In this paper we consider the edge ranking problem of weighted trees. We prove that a special instance of this problem, namely edge ranking of multitrees is NP-hard already for m...
In previous papers [1, 2], we proposed a subspace distance. However, whether the subspace distance satisfies the triangle inequality was left open. In this note, we give positive ...
