Comparative Insights Into the Degree of Conversion of a 3D‐Printed Photopolymer Occlusal Splint Resin Fabricated by Stereolithography and Masked Stereolithography Compared to Heat‐Polymerized Acrylics

open access: yesMacromolecular Materials and Engineering, EarlyView.
This study compares the degree of conversion (DC) of a three‐dimensionally (3D)‐printed photopolymer occlusal splint resin fabricated using stereolithography (SLA) and masked stereolithography (MSLA) printing technologies against conventional heat‐polymerized acrylic resins.

Toward accurate machine learning‐driven prediction of polymeric composites properties based on experimental data

open access: yesMaterials Genome Engineering Advances, EarlyView.
We employed AI models to leverage raw material and product grade information to predict polymer composite properties, utilizing advanced data representation methods to enhance model performance. Our model accurately predicts mechanical and thermal properties, including flexural strength, tensile yield strength, and thermal conductivity.

Dynamic Characteristics of Vibrating Flip‐Flow Screens Considering Material Impact Force

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Vibrating flip‐flow screens are widely used in the field of screening; its actual operation is affected by the impact force of materials, but existing research usually ignores this effect. Based on this background, considering the influence of material impact force and moment on vibrating flip‐flow screens, this paper develops a dynamic model ...

NExT‐LF: A Novel Operational Modal Analysis Method via Tangential Interpolation

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Operational modal analysis (OMA) is vital for identifying modal parameters under real‐world conditions, yet existing methods often face challenges with noise sensitivity and stability. This study introduces NExT‐LF, a novel method that combines the well‐known Natural Excitation Technique (NExT) with the Loewner Framework (LF). NExT enables the

Robust Control for Uncertain Vertical Electric Stabilization System With Flexible Nonlinearity Using Backstepping Idea

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT A robust control method for the uncertain vertical electric stabilization system (VESS) with flexible nonlinearity is proposed, and the mismatched uncertainty is considered and compensated based on the backstepping idea. First, based on evaluating the coupling effects of the flexible nonlinearity, the analytical dynamics model of the VESS is ...
