Tracking contact transitions during force-controlled compliant motion using an interacting multiple model estimator [PDF]

open access: yes, 2001
This work concerns both monitoring of contact transitions and estimation of the unknown first-order geometric parameters during force-controlled motions. The robotic system is required to move an object among a sequence of contact configurations with the

Infinitesimal symmetries in contact Hamiltonian systems

open access: yes, 2021
In this paper, we extend the well-known Noether theorem for Lagrangian systems to contact Lagrangian systems. We introduce a classification of infinitesimal symmetries and obtain the corresponding dissipated quantities. We notice that in contact dynamics,

On Lie algebras of generators of infinitesimal symmetries of almost-cosymplectic-contact structures [PDF]

open access: yes, 2016
summary:We study Lie algebras of generators of infinitesimal symmetries of almost-cosymplectic-contact structures of odd dimensional manifolds. The almost-cosymplectic-contact structure admits on the sheaf of pairs of 1-forms and functions the structure ...

On derivative-dependent infinitesimal deformations of differentiable maps [PDF]

open access: yes, 1980
We study, by means of flows in jet bundles, infinitesimal deformations of germs of b∞ maps ƒ:Rn→Rm that depend on a finite number of derivatives of these maps.

CONFORMAL INFINITESIMAL TRANSFORMATIONS IN AN ALMOST r-CONTACT HYPERBOLIC PRODUCT MANIFOLD

open access: yesDemonstratio Mathematica, 1986
The authors give necessary and sufficient conditions for a vector field to be an infinitesimal conformal transformation in an almost r-contact hyperbolic manifold defined by \textit{K. K. Dube} and \textit{R. Niwas} [Demonstr. Math. 11, 887-897 (1978; Zbl 0402.53020)].

On Infinitesimal Projective Transformations of the Tangent Bendle With the Complete Lift of A Finsler Metric [PDF]

open access: yes, 2017
Let (M,g) be a Finsler manifold and TM0 its slit tangent bundle with the complete lift metric ~g.In this paper we prove that every infinitesimal complete lift projective transformation on (TM0,~g), is an infinitesimal affine transformation. Moreover, if (
