Analysis of the approaches used for calculating involute splined couplings and the methods of considering their influence on the dynamic behavior of systems

Научный вестник МГТУ ГА, 2023
Spline couplings, due to their high reliability and strength parameters, are widespread not only in mechanical engineering. The ability to transmit high torque with a sufficiently long service life has led to the extensive use of these couplings in the ...

Wave Runup Prediction and Alongshore Variability on a Pocket Gravel Beach under Fetch-Limited Wave Conditions

Journal of Marine Science and Engineering, 2023
Most empirical equations used for wave runup predictions have been developed from measurements at straight sandy beaches in unlimited fetch environments.

Influence of Beach Slope on Morphological Changes and Sediment Transport under Irregular Waves

Journal of Marine Science and Engineering, 2023
This paper presents new data from large-scale wave flume experiments. It shows the beach profile evolution and sediment transport for two different bed slopes (1:15 and 1:25), and three irregular high-energy erosive wave conditions and one low-energy ...

Measurement of Oil Film Thickness Distribution between a Slipper and Swash Plate in Swash-Plate-Type Axial Piston Pumps

Tribology Online, 2022
In this study, slipper/swash plate sliding test rigs were developed to measure oil film thickness distribution. For this purpose, fluorescence measurement was performed with a sapphire glass swash plate and a light emitting diode as the light source. The

Observations of nonlinear run-up patterns on plane and rhythmic beach morphology [PDF]

, 2010
Application of non-linear forecasting and bispectral analysis to video observations of run-up over cuspate topography shows that these alongshore patterns in the morphology are accompanied by changes to the fundamental behaviour of the run-up timeseries.

A Conceptual Model for Spatial Grain Size Variability on the Surface of and within Beaches

Journal of Marine Science and Engineering, 2016
Grain size on the surface of natural beaches has been observed to vary spatially and temporally with morphology and wave energy. The stratigraphy of the beach at Duck, North Carolina, USA was examined using 36 vibracores (~1–1.5 m long) collected along a

An analytical model for bore-driven run-up [PDF]

, 2008
We use a hodograph transformation and a boundary integral method to derive a new analytical solution to the shallow-water equations describing bore-generated run-up on a plane beach.

Occasional essay: upper motor neuron syndrome in amyotrophic lateral sclerosis [PDF]

, 2020
The diagnosis of amyotrophic lateral sclerosis (ALS) requires recognition of both lower (LMN) and upper motor neuron (UMN) dysfunction.1 However, classical UMN signs are frequently difficult to identify in ALS.2 LMN involvement is sensitively detected ...

Storm Waves at the Shoreline: When and Where Are Infragravity Waves Important?

Journal of Marine Science and Engineering, 2019
Infragravity waves (frequency, f = 0.005–0.05 Hz) are known to dominate hydrodynamic and sediment transport processes close to the shoreline on low-sloping sandy beaches, especially when incident waves are large.
