We suggest a mathematical potential well with spherical symmetry and apply to the 1d Schrödinger equation. We use some well known techniques as Stationary Perturbation Theory and WKB to gain insight ...

Abstract: In this paper, we consider the H 2 (or Kalman)-filtering problem for discrete-time singularly-perturbed (two time-scale) nonlinear systems. Two types of filters, namely, i) decomposition and ...

Our recent evidence shows that vertical accelerations of the rider's centre of mass (CoM) are substantial when cycling off the saddle. These accelerations are caused by interaction forces between the ...
