Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)

open access: yesAdvanced Engineering Materials, EarlyView.
Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...

The Effect of Drill Rotational Speed on Drilling Resistance in Non-Destructive Testing of Concrete

open access: yesApplied Sciences
Drilling resistance (DR) measurement is a promising non-destructive technique for evaluating the mechanical properties of concrete. However, the reliability and repeatability of DR measurements are still limited by an insufficient understanding of how ...

A New Method for Determining Horizontal Impact Load Based on Rotational Speed of Aircraft Wheel in Landing Gear Drop Test

open access: yesMATEC Web of Conferences, 2017
The maximum horizontal impact load experienced by the aircraft landing gear wheel during landing is an important parameter in landing gear safety design and performance analysis. Using a non-contact photoelectric testing method, this paper experimentally

Apparent length of a rotating arc-line as a function of speed of rotation

open access: yesActa Psychologica, 1968
Abstract Magnitude estimates were obtained of 3, 6, 9 and 12 cm illuminated arcs rotating at 30, 45, 60 and 75 r.p.m. in a path of rotation twelve degrees from the point of fixation. The Ansbacher Shrinkage Effect was obtained, there being a tendency for greater shrinkage with increase in speed.

Position control under simultaneous limited torque and speed of a torque-driven nonlinear rotational mechanism [PDF]

open access: yes, 2016
"This paper deals with shaft displacement regulation (position control) of a torque-driven nonlinear gravity unbalanced mechanism under both prescribed bounded torque and speed. This is a novel control objective formulation for mechanisms.

On Critical Speeds Induced by Ball Bearings in Lower Rotating Speeds

open access: yesTransactions of the Japan Society of Mechanical Engineers, 1957
When single-row radial ball bearings are used, several critical speeds take place in a vertical shaft at certain rotating speeds lower than the major critical speed. When the bearing center line of both bearing pedestals is not in alignment and the shaft is not in a perfectly straight line, there is the possibility that these critical speeds occur. The

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...
