Higher-order derivatives of rigid body dynamics with application to the dynamic balance of spatial linkages

open access: yesMechanism and Machine Theory, 2021
Dynamic balance eliminates the fluctuating reaction forces and moments induced by high-speed robots that would otherwise cause undesired base vibrations, noise and accuracy loss. Many balancing procedures, such as the addition of counter-rotating inertia

Tensor Methods for Minimizing Convex Functions with Hölder Continuous Higher-Order Derivatives [PDF]

open access: yesSIAM Journal on Optimization, 2019
In this paper we study p-order methods for unconstrained minimization of convex functions that are p-times differentiable (p ≥ 2) with n-Holder continuous p th derivatives. We propose tensor schemes with and without acceleration.

Chebyshev approximation and higher order derivatives of Lyapunov functions for estimating the domain of attraction [PDF]

open access: yesIEEE Conference on Decision and Control, 2017
Estimating the Domain of Attraction (DA) of non-polynomial systems is a challenging problem. Taylor expansion is widely adopted for transforming a nonlinear analytic function into a polynomial function, but the performance of Taylor expansion is not ...

open access: yesSymmetry, 2020
In the present paper, we deal with some general estimates for the difference of operators which are associated with different fundamental functions.

Computing high-order derivatives in compact integrated-RBF stencils [PDF]

open access: yes, 2022
In Mai-Duy and Strunin (Mai-Duy and Strunin, 2021), it was shown that the inclusion of nodal values of high-order derivatives in compact local integrated-radial-basis-function (IRBF) stencils results in a significant improvement in the solution accuracy.

Coefficients and higher order derivatives of cyclotomic polynomials: Old and new [PDF]

open access: yesExpositiones mathematicae, 2018
The $n^{th}$ cyclotomic polynomial $\Phi_n(x)$ is the minimal polynomial of an $n^{th}$ primitive root of unity. Its coefficients are the subject of intensive study and some formulas are known for them.

On Certain Classes of Multivalent Analytic Functions Defined with Higher-Order Derivatives

open access: yesMathematics, 2022
This paper examines two subclasses of multivalent analytic functions defined with higher-order derivatives. These classes of functions are generalizations of several known subclasses that have been studied in separate works.

Herglotz Variational Problems Involving Distributed-Order Fractional Derivatives with Arbitrary Smooth Kernels

open access: yesFractal and Fractional, 2022
In this paper, we consider Herglotz-type variational problems dealing with fractional derivatives of distributed-order with respect to another function.

Exploiting Higher-order Derivates in Convex Optimization Methods

open access: yes, 2023
Exploiting higher-order derivatives in convex optimization is known at least since 1970's. In each iteration higher-order (also called tensor) methods minimize a regularized Taylor expansion of the objective function, which leads to faster convergence ...

Bosonic Casimir Effect in an Aether-like Lorentz-Violating Scenario with Higher Order Derivatives

open access: yesUniverse, 2023
In this paper, we investigate the bosonic Casimir effect in a Lorentz-violating symmetry scenario. The theoretical model adopted consists of a real massive scalar quantum field confined in a region between two large parallel plates, having its dynamics ...
