Stability of the Simplest Periodic Solutions in the Stuart–Landau Equation with Large Delay

open access: yesМоделирование и анализ информационных систем, 2015
We study the local dynamics of the Stuart–Landau equation with large delay in the neibourhood of periodic solutions. We find sufficient conditions of instability of periodic solutions and sufficient conditions of their stability.

Asymptotic estimations of the solution for a singularly perturbed equation with unbounded boundary conditions

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2022
The paper studies a two-point boundary value problem with unbounded boundary conditions for a linear singularly perturbed differential equation. Asymptotic estimates are given for a linearly independent system of solutions of a homogeneous perturbed ...

Hardness of SIS and LWE with Small Parameters [PDF]

open access: yes, 2013
The Short Integer Solution (SIS) and Learning With Errors (LWE) problems are the foundations for countless applications in lattice-based cryptography, and are provably as hard as approximate lattice problems in the worst case. An important question from both a practical and theoretical perspective is how small their parameters can be made, while ...

Apparent mass of small children: Modelling

open access: yes, 2007
Mass-spring-damper models are widely available for quantifying the whole-body vibration characteristics of primates, human adolescents and human adults, but no models have previously been developed for small children.

Post-manoeuvre and online parameter estimation for manned and unmanned aircraft [PDF]

open access: yes, 2013
Parameterised analytical models that describe the trimmed inflight behaviour of classical aircraft have been studied and are widely accepted by the flight dynamics community.

Small area estimation: new developments and directions

open access: yes, 2002
The purpose of this paper is to provide a critical review of the main advances in small area estimation (SAE) methods in recent years. We also discuss some of the earlier developments, which serve as a necessary background for the new studies. The review

A modified perturbation method in which the applicable range of a small parameter for the solution is extended much larger than that by the conventional perturbation method

open access: yesMechanical Engineering Journal, 2021
A modified perturbation method, in which the applicable range of a small parameter ε for the solution is extended larger than that by the conventional perturbation method, is applied to two simple heat transfer problems with temperature-dependent thermal

Reducing Friction with a Liquid Film on the Body Surface

open access: yesLubricants, 2018
A flow of a thin layer of liquid is simulated on a flat surface of a body located in a stream of air. Liquid film on the surface of the body reduces frictional resistance and can be used as a boundary layer control element.

Parameter Redundancy with Applications in Statistical Ecology [PDF]

open access: yes, 2014
This thesis is concerned with parameter redundancy in statistical ecology models. If it is not possible to estimate all the parameters, a model is termed parameter redundant.
