Toroidal modeling of penetration of the resonant magnetic perturbation field [PDF]
, 2013 A toroidal, quasi-linear model is proposed to study the penetration dynamics of the resonant magnetic perturbation (RMP) field into the plasma. The model couples the linear, fluid plasma response to a toroidal momentum balance equation, which includes ...

Timoshenko beam effect in flexural resonant column tests
Soils and Foundations, 2019 Abstract Current methods for deriving Young’s modulus (E) from flexural resonant column tests do not account for the Timoshenko beam effect. Hence, the extent of the Timoshenko beam effect is investigated in this study using a series of numerical experiments performed by finite element program LS-DYNA.

Disentangling 2:1 resonant radial velocity orbits from eccentric ones and a case study for HD 27894 [PDF]
, 2015 In radial velocity observations, a pair of extrasolar planets near a 2:1 orbital resonance can be misinterpreted as a single eccentric planet, if data are sparse and measurement precision insufficient to distinguish between these models. We determine the

Experimental Study on Damping Ratio Characteristics of Loose Silty Fine Sand at Different Saturations [PDF]
长江科学院院报[Objective] Current research on the damping ratio evolution of silty fine sand under varying saturation conditions remains relatively limited, and in particular, systematic investigations revealing the mechanisms by which saturation variations influence ...

Radio-frequency impedance measurements using a tunnel-diode oscillator (TDO) technique
, 1999 A resonant method based on a tunnel-diode oscillator (TDO) for precision measurements of relative impedance changes in materials, is described. The system consists of an effective self-resonant LC-tank circuit driven by a forward-biased tunnel diode ...

Preliminary findings on the experimental investigation of the small-strain behaviour of Pizzoli silty sand [PDF]
E3S Web of ConferencesThe dynamic properties of soils play a crucial role in solving many geotechnical problems with special attention to earthquake engineering. In particular, the small-strain soil behavior should be accurately reproduced in geotechnical modelling to allow ...
