Moment Theory for Weak Chebyshev Systems with Applications to Monosplines, Quadrature Formulae and Best One-Sided $L^1 $-Approximation by Spline Functions with Fixed Knots

SIAM Journal on Mathematical Analysis, 1977
The chief purpose of this paper is to present an alternative approach to results concerning the existence and uniqueness of monosplines which have a maximum number of zeros (the fundamental theorem of algebra for monosplines). In addition, we discuss the related problems of “double precision” quadrature formulae and one-sided $L^1 $-approximation by ...

Optimal control of linear fractional-order delay systems with a piecewise constant order based on a generalized fractional Chebyshev basis

Journal of Vibration and Control, 2022
This research studies optimal control of a new subclass of variable-order fractional delay systems whose its order is a piecewise constant function. This category of systems has not been discussed in the literature yet.

Comparative study of approximation using Lagrange and Hermite form of polynomial interpolations

2021 International Conference on Computing, Communication, and Intelligent Systems (ICCCIS), 2021
Interpolation means replacing complicated function by simple function which matches at distinct nodes in given interval. Best approximation depends on choice of calculating method, number of nodes and type of nodes.

A Group Theoretic Metric for Robot State Estimation Leveraging Chebyshev Interpolation

IEEE International Conference on Robotics and Automation
We propose a new metric for robot state estimation based on the recently introduced SE2(3) Lie group definition. Our metric is related to prior metrics for SLAM but explicitly takes into account the linear velocity of the state estimate, improving over ...

Polar Affine Arithmetic

ACM Transactions on Mathematical Software, 2019
Uncertainties practically arise from numerous factors, such as ambiguous information, inaccurate model, and environment disturbance. Interval arithmetic has emerged to solve problems with uncertain parameters, especially in the computational process ...
