Abstract: In this paper, item (S2) of Section 3, page 464, should read2 ϕ(q,t)=0,ψ(q,q̇,t)=0, with ϕ(q0,0)=0,ϕ̇(q0,0)=0, and ψ(q0,q̇0,0)=0.

Abstract: In this paper we develop an analytical set of equations to describe the motion of discrete dynamical systems subjected to holonomic and/or nonholonomic Pfaffian equality constraints. These equations ...

Abstract: Suppose imprecise observations are made on imprecisely defined nonlinear processes, and one wishes to estimate the state of the process at certain fixed instants of time lying within the interval ...

Abstract: This paper presents the general form of the explicit equations of motion for mechanical systems. The systems may have holonomic and/or nonholonomic constraints, and the constraint forces may or ...

Abstract: Since its inception about 200 years ago, Lagrangian mechanics has been based upon the Principle of D’Alembert. There are, however, many physical situations where this confining principle is not ...
