Influence of the time-varying gear mesh stiffness on the vibration response of a spur gear pair

open access: yes, 2014
Health monitoring is an essential part of preventive maintenance on gearboxes. This process involves the observation of the operation of gearboxes using an array of sensors to pick up important vibration signals which can be further processed to extract ...

Thermoplastic Dielectric Coatings for Flexible Electrodynamic Dust Shields: Structural and Functional Performance

open access: yesAdvanced Materials Interfaces, EarlyView.
Thermoplastic attachment is introduced as a scalable surface coating strategy to improve the durability and dielectric reliability of flexible electrodynamic dust shields. By embedding chemically modified reduced graphene oxide (CMrGO) electrodes within thermoplastic laminates, mechanical degradation, abrasion damage, and vacuum‐induced electrical ...

Bilayered PEDOT:PSS–Collagen Scaffolds as Functional Architectures for Tissue Engineering

open access: yesAdvanced Materials Interfaces, EarlyView.
A bilayered scaffold integrates collagen and PEDOT:PSS as distinct yet interconnected 3D matrices, preserving their fibrillar and conductive characteristics. Spatial compartmentalization enables independent tailoring of each domain while maintaining mechanical stability and compatibility with electrochemical monitoring, providing a multifunctional ...

Reducing Interfacial Separation Force in High‐Speed Constrained‐Surface Projection Stereolithography Using a Dual‐Modulus Silicone Release Film

open access: yesAdvanced Materials Interfaces, EarlyView.
A dual‐modulus silicone release film creates distributed stress concentrations at high‐/low‐modulus boundaries, triggering multi‐site crack initiation and rapid interfacial detachment. The architecture lowers the peak separation force by 97.6%, shortens detachment time, and enables stable continuous projection stereolithography at 720 mm h−1, offering ...

Expected optimal feedback with Time-Varying Parameters [PDF]

open access: yes
In this paper we derive, by using dynamic programming, the closed loop form of the Expected Optimal Feedback rule with time varying parameter. As such this paper extends the work of Kendrick (1981, 2002, Chapter 6) for the time varying parameter case ...
