The paper deals with the well–posedness of the problem 8 >< >: utt −∆u = 0 in R× Ω, utt = kuν on R× Γ, u(0, x) = u0(x), ut(0, x) = v0(x) in Ω, where u = u(t, x), t ∈ R, x ∈ Ω, ∆ = ∆x denotes the Laplacian operator respect to the space variable, Ω is a bounded regular (C∞) open domain of RN (N ≥ 1), Γ = ∂Ω, ν is the outward normal to Ω, k is a constant. We prove that it is ill–posed if N ≥ 2, wh...

Let M either be a closed real analytic Riemannian manifold or a closed C∞-Riemannian surface. We estimate from below the volume of a nodal domain component in an arbitrary ball, provided that this component enters the ball deeply enough.

The article presents the steps required to reconstruct a 3D trajectory of a golf ball flight, bounces and roll in short game. Two video cameras were used to capture the last parts of the trajectories including the bounces and roll. Each video sequence is processed and the ball is detected and tracked until is stops. Detected positions from both video sequences are then matched and 3D trajectory...

Recently there has been great deal of interest in making system that enables an audience to view sports event from any arbitrary viewpoint. The rapid development of networks and computers will soon make it possible to provide a form of real-time video that allows the viewer to select any desired view of the action. This paper introduces a novel method for generating an arbitrary view of a scene...

After seven previous meetings between his Great Danes of Albany and the Owls of Southern Connecticut, Albany State head coach Bob Ford has learned to respect his team's annual out-of-state opponent. He has good reason. In the past, Mhniiy has held the upper hand over the Owls. The Danes lead the yearly series bcl» cm the two teams with a 5-2 advantage. Bu: tomorrow Albany will face a very diffe...
