High-Resolution Cooperate Density-Integrated Inversion Method of Airborne Gravity and Its Gradient Data

open access: yesRemote Sensing, 2021
Airborne (or satellite) gravity measurement is a commonly used remote sensing method to obtain the underground density distribution. Airborne gravity gradiometry data have a higher horizontal resolution to shallower causative sources than airborne ...

Structural joint inversion on irregular meshes

open access: yesGeophysical Journal International, 2019
SUMMARY Structural joint inversion of several data sets on an irregular mesh requires appropriate coupling operators. To date, joint inversion algorithms are primarily designed for the use on regular rectilinear grids and impose structural similarity in the direct neighbourhood of a cell only.

Function of ankle ligaments for subtalar and talocrural joint stability during an inversion movement – an in vitro study

open access: yesJournal of Foot and Ankle Research, 2019
Background The lateral ankle ligament complex consisting of the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL) and the posterior talofibular ligament (PTFL) is known to provide stability against ankle joint inversion.

Joint inversion of muon tomography and gravimetry - a resolving kernel approach [PDF]

open access: yes, 2014
Both muon tomography and gravimetry are geophysical methods that provide information on the density structure of the Earth's subsurface. Muon tomography measures the natural flux of cosmic muons and its attenuation produced by the screening effect of the

Dressed-State Approach to Population Trapping in the Jaynes-Cummings Model [PDF]

open access: yes, 1999
The phenomenon of atomic population trapping in the Jaynes-Cummings Model is analysed from a dressed-state point of view. A general condition for the occurrence of partial or total trapping from an arbitrary, pure initial atom-field state is obtained in ...

Joint sparsity-driven inversion and model error correction for radar imaging [PDF]

open access: yes, 2009
Solution of inverse problems in imaging requires the use of a mathematical model of the observation process. However such models often involve errors and uncertainties themselves. The application of interest in this paper is synthetic aperture radar (SAR)

Joint Inversion of Atmospheric Refractivity Profile Based on Ground-Based GPS Phase Delay and Propagation Loss

open access: yesAtmosphere, 2016
In this paper, we present a new estimation of the atmospheric refractivity profile combining the scattering signal (electromagnetic wave propagation loss) and the direct signal (phase delay). The refractivity profile is modeled using four parameters, i.e.
