Proposal of new vibro-acoustic floor

MATEC Web of Conferences, 2018
Human perception of vibration could be the basic parameter in designing a new buildings located close to public transport. It is also one of parameter that is considered in diagnosis of building vibration.

Controlling multistability in a vibro-impact capsule system

Nonlinear Dynamics, 2017
This work concerns the control of multistability in a vibro-impact capsule system driven by a harmonic excitation. The capsule is able to move forward and backward in a rectilinear direction, and the main objective of this work is to control such motion in the presence of multiple coexisting periodic solutions.

Forward and backward motion control of a vibro-impact capsule system [PDF]

International Journal of Non-Linear Mechanics, 2015
A capsule system driven by a harmonic force applied to its inner mass is considered in this study. Four various friction models are employed to describe motion of the capsule in different environments taking into account Coulomb friction, viscous damping, Stribeck effect, pre-sliding, and frictional memory.

Mathematical modeling of the technological process of the rock destruction by a vibro impact device with a hydro pulse drive.

Trudy Odesskogo Politehničeskogo Universiteta, 2018
The high efficiency of the technological process of destruction of the rock with the help of vibration of shock loads has been proved. A high degree of intensification of the process of rock destruction is achieved by using the developed original design

The Vibro-Acoustic Characteristics Analysis of the Coupled System between Composite Laminated Rotationally Stiffened Plate and Acoustic Cavities

Applied Sciences
In order to study vibro-acoustic characteristics between composite laminated rotationally stiffened plate and acoustic cavities in the coupled system, first-order shear deformation theory (FSDT) and modified Fourier series are used to construct a unified

HOPF BIFURCATION OF A TWO-DEGREE-OF-FREEDOM VIBRO-IMPACT SYSTEM [PDF]

Journal of Sound and Vibration, 1998
The bifurcation problem of a two-degree-of-freedom system vibrating against a rigid surface is studied in this paper. It is shown that there exist Hopf bifurcations in the vibro-impact systems with two or more degrees of freedom under suitable system parameters.

Nonlinear Asymmetric Blood Oxygenation Level Dependent Responses in Somatosensory Cortex

Human Brain Mapping, Volume 47, Issue 5, 1 April 2026.
BOLD responses to increments and decrements in intensity of vibrotactile stimulation were asymmetric. Negative BOLD effects (decrements in signal) were smaller in amplitude and slower to peak compared with positive BOLD responses to increases of intensity. BOLD responses were nonlinear for changes in stimulus duration and intensity.

Integrating Biological Architecture and Biomaterial Function: Exploring the Native Hydrogel Structure of Brown Seaweed

Macromolecular Bioscience, Volume 26, Issue 4, April 2026.
This study explores the natural internal structure of brown seaweed and how it influences material behavior. By preserving and reassembling the seaweed's native architecture, hydrogels and foams with high liquid absorption, porosity, and shape recovery were created using minimal processing.
