Nonlinear regression analysis

open access: yes, 2023
Nonlinear regression analysis is a popular and important tool for scientists and engineers. In this article, we introduce theories and methods of nonlinear regression and its statistical inferences using the frequentist and Bayesian statistical modeling and computation.

Nonlinear Drillstring Dynamics Analysis [PDF]

open access: yesSIAM Journal on Applied Dynamical Systems, 2009
This paper studies the dynamical response of a rotary drilling system with a drag bit, using a lumped parameter model that takes into consideration the axial and torsional vibration modes of the bit. These vibrations are coupled through a bit-rock interaction law.

Nonlinear Analysis of Juxtacrine Patterns [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2001
Summary: We investigate a discrete mathematical model for a type of cell-cell communication in early development which has the potential to generate a wide range of spatial patterns. Our previous work on this model has highlighted surprising differences between the predictions of linear analysis and the results of numerical simulations.

On a coupled system of higher order nonlinear Caputo fractional differential equations with coupled Riemann–Stieltjes type integro-multipoint boundary conditions

open access: yesAdvances in Difference Equations, 2019
We study a coupled system of Caputo fractional differential equations with coupled non-conjugate Riemann–Stieltjes type integro-multipoint boundary conditions. Existence and uniqueness results for the given boundary value problem are obtained by applying

The Space of Functions with Tempered Increments on a Locally Compact and Countable at Infinity Metric Space

open access: yesAxioms, 2021
The aim of the paper is to introduce the Banach space consisting of real functions defined on a locally compact and countable at infinity metric space and having increments tempered by a modulus of continuity.
