Field Test on Buoyancy Variation of a Subsea Bottom-Supported Foundation Model
The bottom-supported foundation is the most important component of offshore platforms, as it provides the major support to the upper structure. The buoyancy of the bottom-supported foundation is a critical issue in platform design because it counteracts ...

Applicability of extended modified Archimedes’ law to various granular and intruder properties
The version of record of this article, first published in Computational Particle Mechanics (2025), is available online at Publisher’s website: https://doi.org/10.1007/s40571-025-01025-9. Although resistive force during intruder penetration into granular layers plays a crucial role in various applications, its underlying mechanisms remain insufficiently

Nonlinear impedance matching control for a submerged wave energy converter
The impedance matching control, also known as approximate complex conjugate control (ACC), is one of the main strategies for improving the capture of energy by point absorber wave energy converters. Such a strategy shapes the mechanical impedance related

A Study of the Properties of Electrical Insulation Oils and of the Components of Natural Oils
This paper presents a study of the electrical and non-electrical properties of insulating oils. For the correct choice of an electrical insulation oil, it is necessary to know its density, dynamic viscosity, dielectric constant, loss number and ...

Hole Diameter and Sinking Time of Water Clocks
Water clocks measure time by controlling the flow of water into a container. Ancient Persians used the sinking time of Fenjaans, bowls with holes in the center, as a metric for time.

Crystal and magnetic structure of hexagonal anisotropic polycrystalline ferrites SrFe12O19 obtained by radiation-thermal sintering [PDF]
Hexagonal anisotropic strontium ferrite has found wide application in the fabrication of permanent magnets, active media of UHF electronic devices, and photonics. The performance of hexagonal strontium ferrites depends largely on the synthesis technology.

Galilean Hydrostatic Paradox and Archimedes Law
A pedagogia tradicional tem subestimado a presença de certos mistérios e paradoxos no ensino da Física. Abordagens indutivistas ingênuas na educação em ciência têm também contribuído para que alguns importantes pressupostos teóricos sejam usualmente ignorados. Uma análise histórica, conceitual e experimental do desenvolvimento da Física pode contribuir

Buoyant force in a nonuniform gravitational field
When an arbitrarily-shaped body is fully immersed in a liquid in equilibrium, it gets from the liquid a non-null hydrostatic force known as buoyant force. It is an easy task to apply the divergence theorem to show that this force agrees to that predicted
