Contact forces between roller and cage pocket in cylindrical roller bearings (Consideration based on dynamic behavior between roller and cage)

open access: yesNihon Kikai Gakkai ronbunshu, 2022
When rolling bearings are used under light loads and high rotational speeds, their life may be determined by cage wear rather than raceway flaking. Under these operating conditions, the life and reliability of the bearings can be improved by reducing ...

Formulation of Impulsive Ecological Systems Using the Conformable Calculus Approach: Qualitative Analysis

open access: yesMathematics, 2023
In this paper, an impulsive conformable fractional Lotka–Volterra model with dispersion is introduced. Since the concept of conformable derivatives avoids some limitations of the classical fractional-order derivatives, it is more suitable for applied ...

Impulse Oscillometry

open access: yesAdvances in Respiratory Medicine, 2019
Pulmonary function testing involves a battery of tests from the simple pulse oximetry to the cardiopulmonary exercise testing. Impulse oscillometry (IOS) is one of the newly described pulmonary function tests. It is based on the old principle of forced oscillatory technique modified and refined as per research and advances. It involves the use of sound

On Impulsive Delay Integrodifferential Equations with Integral Impulses [PDF]

open access: yesMediterranean Journal of Mathematics, 2020
The present research paper is devoted to investigate the existence, uniqueness of mild solutions for impulsive delay integrodifferential equations with integral impulses in Banach spaces. We also investigate the dependence of solutions on initial conditions, parameters and the functions involved in the equations.
