Standing waves braneworlds [PDF]

International Journal of Modern Physics D, 2016
The class of nonstationary braneworld models generated by the coupled gravitational and scalar fields is reviewed. The model represents a brane in a spacetime with single time and one large (infinite) and several small (compact) spacelike extra dimensions.

Simulations and Experimental Analysis of a High Viscosity Inkjet Printing Device Based on Fabry–Pérot Resonator

Sensors, 2022
The study investigates the effect of changing various input parameters on the pressure responses at acoustic cavities of a droplet-based acoustic printing device consisting of a Fabry–Pérot (FP) resonator and a standing wave-source chamber.

Phase-Modulated Standing Wave Interferometer

Proceedings, 2020
Standing wave interferometers (SWIs) show enormous potential for miniaturization because of their simple linear optical set-up, consisting only of a laser source, a measuring mirror and two standing wave sensors for obtaining quadrature signals.

Diagnostic accuracy of the response to the brief tachycardia provoked by standing in children suspected for long QT syndrome

Heart Rhythm O2, 2021
Background: Adult long QT syndrome (LQTS) patients have inadequate corrected QT interval (QTc) shortening and an abnormal T-wave response to the sudden heart rate acceleration provoked by standing.

A paradigm shift in the quantification of wave energy attenuation due to saltmarshes based on their standing biomass

Scientific Reports, 2022
Most existing analytical and numerical models to quantify wave energy attenuation attributed to saltmarshes are based on the definition of a drag coefficient that varies with vegetation and wave characteristics and requires calibration, i.e., a case ...

Researched on the bias stability of the HRG affected by the temperature and the standing wave azimuth

Measurement + Control, 2020
The force-to-rebalanced control mode is the main operating mechanism of the HRG, and the standing wave azimuth of the resonator points to the 0° direction. But the bias of the HRG is very sensitive to the change of external physical field environment and

Dynamics of an acoustically trapped sphere in beating sound waves

Physical Review Research, 2021
A focused acoustic standing wave creates a Hookean potential well for a small sphere and can levitate it stably against gravity. Exposing the trapped sphere to a second transverse traveling sound wave imposes an additional acoustic force that drives the ...

Human Standing Posture Motion Evaluation by the Visual Simulation of Multi-Directional Sea-Waves

Sensors, 2022
Crew fatigue from standing posture motion, caused by ship motion, can lead to marine accidents. Therefore, the mechanism of fatigue in crew members ought to be elucidated.

Flutter and forced response of mistuned rotors using standing wave analysis [PDF]

, 1983
A standing wave approach is applied to the analysis of the flutter and forced response of tuned and mistuned rotors. The traditional traveling wave cascade airforces are recast into standing wave arbitrary motion form using Pade approximants, and the ...
