A model of piston impact and vibration for internal combustion engine noise reduction
In this paper a mathematical model is developed to study piston impact and cylinder liner vibration in internal combustion engines. The aim of this study is to assess the effect on cylinder liner response (and, therefore on piston-impact induced noise ...

We employ freeform printing of thermo‐responsive poly(2‐oxazoline) to directly fabricate suspended sacrificial vascular templates within Organ‐on‐a‐chip devices. This enables circular, perfusable channels down to 200 µm without post‐processing.

Hierarchically Porous Coatings for Cellulose Fibers by Core–Shell Particle Templating
Hybrid and functional core–shell particles comprising a silica core and a polymer shell were synthesized and used to develop a coating and etching process applied to a cellulose substrate. This resulted in highly porous, functional coatings on a cellulose membrane for further application in cellulose‐based adsorbers and advanced membrane technology ...

ABSTRACT Hydraulic manipulators exhibit strong coupling, pronounced nonlinearities, and significant modeling uncertainties, which hinder high‐precision motion control. This paper proposes a finite‐time disturbance observer–based nonlinear robust adaptive control (RAC‐FTDO) framework enhanced by a physically consistent dynamic parameter identification ...
