Experimental analysis of ultralight aircraft tyre behaviour under aircraft landing phase

open access: yesAviation, 2022
The aim of the research described in this paper is analysis of the deformation of the aircraft tyre subjected to static load. Based on the results of experimental tests with a different value of inflation pressure, favorable pressure conditions for use ...

On the determination of the deflection of the vertical by satellite altimetry

open access: yesMarine Geodesy, 1984
Abstract With the advent of satellite altimetry it has become possible to estimate the height of the marine geoid above the ellipsoid to an accuracy of better than 1 m. At a crossover of a satellite's ascending and descending tracks, altimeter data can be used to obtain two linearly independent estimates of the geoid's horizontal gradient.

The Ekman spiral for piecewise-uniform viscosity [PDF]

open access: yesOcean Science, 2020
We re-visit Ekman's (1905) classic problem of wind-stress-induced ocean currents to help interpret observed deviations from Ekman's theory, in particular from the predicted surface current deflection of 45∘.

The long-term mechanical performance of geogrid-reinforced soil retaining walls under cyclic footing loading

open access: yesCase Studies in Construction Materials, 2022
The soil behind the retaining wall may be subjected to various cyclic loadings, for example, machine vibration, traffic and earthquake loading. To reduce soil deformation and improve the stability of a soil retaining wall, geosynthetics have been widely ...
