— Rigid body dynamics with contact constraints can be solved locally using linear complementarity techniques. However, these techniques do not impose the original constraints and...
A well-known result due to J. T. Stafford asserts that a stably free left module M over the Weyl algebras D = An(k) or Bn(k) − where k is a field of characteristic 0 − with ...
This paper revisits the classical problem of detecting interest points, popularly known as "corners," in 2D images by proposing a technique based on fitting algebraic sh...
—We describe a simple circuit, inspired by the human auditory system, which allows controllable supercritical stability in a sonar receiver. The receiver is held on the threshold...
— In this paper an appropriate four rotors helicopter nonlinear dynamic model for identi cation and control law synthesis is obtained via modelization procedure where several phe...
