Analysis and implementation of fractional-order chaotic system with standard components

open access: yesJournal of Advanced Research, 2020
This paper is devoted to the problem of uncertainty in fractional-order Chaotic systems implemented by means of standard electronic components. The fractional order element (FOE) is typically substituted by one complex impedance network containing a huge

Model of layered pattern formation in binary igneous systems

open access: yesSolid Earth Sciences, 2021
Centimeter to meter-scale repetitive patterns in composition and texture are sometimes observed in igneous systems. Examples are found in layered intrusions and multi-shelled orbicular granites. These patterns may result from the action of nonlinear self-

The role of the bubble–bubble interaction on radial pulsations of bubbles

open access: yesUltrasonics Sonochemistry, 2021
Using a model that with or without considering the interaction between bubbles through the radiated pressure waves, numerical simulations of cavitation bubbles have been performed in order to study the effect of the bubble–bubble interaction on radial ...

Generative and self-supervised domain adaptation for one-stage object detection

open access: yesArray, 2021
Unsupervised cross-domain object detection has recently attracted considerable attention because of its ability to significantly reduce annotation costs. For two-stage detectors, several improvements have been made in feature-level adaptations.

Effect of roll press on consolidation and electric/ionic-path formation of electrodes for all-solid-state battery

open access: yesJournal of Power Sources Advances, 2021
This study investigated unpressed and pressed electrodes with the synchrotron radiation X-ray computed laminography (CL) technique to clarify the relationship between the packing structure formation of an electrode processed with a roll press and the ...

Assessment of the unsteady performance of a turbocharger radial turbine under pulsating flow conditions: Parametric study and modeling

open access: yesEnergy Conversion and Management: X, 2022
A characteristic of radial turbines for turbocharger applications subject to pulsating flow is the deviation of the turbine performance compared with corresponding continuous flow conditions, typically associated with gas-stand experiments.

Structure-property relationships of imperfect additively manufactured lattices based on triply periodic minimal surfaces

open access: yesMaterials & Design, 2022
Lattices based on triply periodic minimal surfaces (TPMS) have recently attracted increasing interest, but their additive manufacturing (AM) is fraught with imperfections that compromise their structural integrity.
