On the Modeling of Hysteretic Oscillations of Mechanical Systems [PDF]

Учёные записки Казанского университета: Серия Физико-математические науки, 2015
The paper considers nonstationary vibrations of mechanical systems with hysteretic dampers. To describe the hysteresis, a phenomenological approach is suggested, which is demonstrated on the problem of forced vibrations produced by the antigalloping ...

On Dynamic Stability of a Nonlinear Aeroelastic System

Известия Иркутского государственного университета: Серия "Математика", 2018
A nonlinear mathematical model of a device related to vibratory technology is considered. The device is intended for the intensification of technological processes, for example, the mixing process. The action of such devices is based on the vibrations of

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

Advanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Noncommutative Quantum Mechanics and rotating frames

, 2002
We study the effect of noncommutativity of space on the physics of a quantum interferometer located in a rotating disk in a gauge field background. To this end, we develop a path-integral approach which allows defining an effective action from which ...

Differential Efficacy of 2 Vibrating Orthodontic Devices to Alter the Cellular Response in Osteoblasts, Fibroblasts, and Osteoclasts

Dose-Response, 2018
Modalities that increase the rate of tooth movement have received considerable attention, but direct comparisons between devices are rare. Here, we contrasted 2 mechanical vibratory devices designed to directly transfer vibrations into alveolar bone as a

Innovating Aircraft Repair Processes: The Role of Digitalization in Sustainability

Advanced Engineering Materials, EarlyView.
This research explores how digitalization—by storing detailed non‐destructive testing data in structured DICONDE databases and creating a standard data model of the component—innovates aviation maintenance and repair processes. Coupled with a developed state‐based simulation model, it enables data‐driven, sustainable repair strategies that reduce waste,

Development of an ADL assistance apparatus for upper limbs and evaluation of muscle and cerebral activity of the user

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2014
This assistance apparatus for upper limbs was developed for patients who can control their fingers but they cannot lift up their arms themselves, for example myopathy and hemiplegic patients.

Qubit compatible superconducting interconnects

, 2017
We present a fabrication process for fully superconducting interconnects compatible with superconducting qubit technology. These interconnects allow for the 3D integration of quantum circuits without introducing lossy amorphous dielectrics.
