Position and Velocity Estimation for Two-Inertia System with Nonlinear Stiffness Based on Acceleration Sensor

open access: yesSensors, 2015
In this paper, we consider the state estimation problem for flexible joint manipulators that involve nonlinear characteristics in their stiffness. The two key ideas of our design are that (a) an accelerometer is used in order that the estimation error ...

Uniqueness of signed measures solving the continuity equation for Osgood vector fields

open access: yes, 2008
Nonnegative measure-valued solutions of the continuity equation are uniquely determined by their initial condition, if the characteristic ODE associated to the velocity field has a unique solution. In this paper we give a partial extension of this result

Boundedness of Commutators of Marcinkiewicz Integrals on Nonhomogeneous Metric Measure Spaces

open access: yesJournal of Function Spaces, 2015
Let (X,d,μ) be a metric measure space satisfying the upper doubling condition and geometrically doubling condition in the sense of Hytönen. The aim of this paper is to establish the boundedness of commutator Mb generated by the Marcinkiewicz integral M ...

Locally Lipschitz Composition Operators in Space of the Functions of Bounded κΦ-Variation

open access: yesJournal of Function Spaces, 2014
We give a necessary and sufficient condition on a function h:R→R under which the nonlinear composition operator H, associated with the function h, Hu(t)=h(u(t)), acts in the space κΦBV[a,b] and satisfies a local Lipschitz condition.

Geometric conditions and existence of bi-Lipschitz parameterizations

open access: yesDuke Mathematical Journal, 1995
Let \(\Sigma\) be a locally compact set of Hausdorff dimension \(n\) in \(\mathbb{R}^{n+ m}\) and \(\zeta_0\) a point of \(\Sigma\). Set \[ \theta(r, \zeta)= \inf_L \{\textstyle{{1\over r}} D[Z\cap B(r, \zeta), L\cap B(r, \zeta)]\}, \] where the infimum is taken over all \(n\)-planes containing \(\zeta\), and \(D\) is the Hausdorff distance.

ON THE STRUCTURE OF THE OPERATOR COADJOINT ACTION FOR THE CURRENT ALGEBRA ON THE THREE-DIMENSIONAL TORUS

open access: yesНаучный вестник МГТУ ГА, 2017
For the current Lie algebra on the three-dimensional torus with non-standard Lie bracket some properties, in the case when the sum of adjoint and coadjoint operators on infinite-dimensional Lie algebra with scalar product has a finite norm are ...
