First principles study of structural properties and electric field gradients in kaolinite
(Elsevier Science, 2019-03-01)
This work reports a gauge-including projected augmented waves (GIPAW) method study of the structural and electronic properties of kaolinite (Al2Si2O5(OH)4). Different equilibrium structures were determined, and the ...
Gradient-Based Cluster Space Navigation for Autonomous Surface Vessels
(Institute of Electrical and Electronics Engineers, 2014-01)
This paper presents an experimentally demonstrated gradient-based multirobot technique for adaptively navigating within a parameter field. To implement this technique, simultaneous measurements of the parameter are made ...
Analysis of long-term potential gradient variations measured in the Argentinian Andes
(Elsevier Science Inc., 2021-01)
Continuous measurements of the potential gradient are being recorded at the CASLEO astronomical observatory near to the Andes Mountain of Argentina, since 2010 (Latitude: 31°47.88′S, Longitude: 69°17.7′W, Altitude: 2552 ...
The GIPAW approach for the study of local structures and the electric field gradients at Cd and Ta impurity sites. Application to doped yttria ceramics
(Elsevier, 2020-01)
We report a first-principles study on the structural properties, the electronic structure and the hyperfine properties of the pure, Cd-, and Ta-doped yttria (Y2O3) using the Gauge-Including Projector Augmented Waves (GIPAW) ...
Swarm equatorial electric field chain: First results
(American Geophysical Union, 2015-01-13)
The eastward equatorial electric field (EEF) in the E region ionosphere drives many important phenomena at low latitudes. We developed a method of estimating the EEF from magnetometer measurements of near‐polar orbiting ...
