Di-Zinc Aryl Complexes
Two new di-zinc aryl complexes, [LZn2Ph2] and [LZn2(C6F5)2], coordinated by a diphenol tetraamine macrocyclic ligand are prepared and fully characterized, including by single crystal X-ray diffraction experiments. The complexes'...

New method for tracking the movement of ionospheric plasma
A method to track the flow of plasma in the Earth's ionosphere is presented. This takes maps of total electron content (TEC) at various times, and by comparing them derives a map of bulk velocities. The method is a modification...

A comparison of the relative effect of the Earth’s Quasi-D.C. and A.C. electric field on Gradient Drift Waves in large-scale plasma structures in the polar regions
Radio signals traversing polar-cap plasma patches and other large-scale plasma structures in polar regions are prone to scintillation. This implies that irregularities in electron concentration often form within such structures....

Isolating the multipath component in GNSS signal-to-noise data and locating reflecting objects
A filter to separate the effect of multipath in Global Navigation Satellite System (GNSS) signal-to-noise ratio (SNR) data is presented. The filter removes multipath cleanly, and affects neither slowly varying trends (such as...

Polar-cap plasma patch primary linear instability growth-rates compared
Four primary plasma instability processes have been proposed in the literature to explain the generation of phase scintillation associated with polar-cap plasma patches. These are the Gradient Drift, Current Convective and...

Tomographic Imaging of Traveling Ionospheric Disturbances Using GNSS and Geostationary Satellite Observations
Abstract Traveling ionospheric disturbances (TIDs) are the manifestations of atmospheric gravity waves in the ionosphere. These disturbances have practical importance because they affect satellite navigation technologies such as...

Imaging of 3-D plasmaspheric electron density using GPS to LEO satellite differential phase observations
This paper outlines a new mathematical approach to imaging the electron density distribution in the high regions of the topside ionosphere and the plasmasphere from 800 km up to 20,200 km altitude using GPS measurements from low...

Reduction in the ionospheric error for a single-frequency GPS timing solution using tomography
Single-frequency Global Positioning System (GPS) receivers do not accurately compensate for the ionospheric delay imposed upon a GPS signal. They rely upon models to compensate for the ionosphere. This delay compensation can be...

Four-dimensional electrical capacitance tomography imaging using experimental data
Electrical capacitance tomography (ECT) is a relatively mature non-invasive imaging technique that attempts to map dielectric permittivity of materials. ECT has become a promising monitoring technique in industrial process...

A 12 year comparison of MIDAS and IRI 2007 ionospheric Total Electron Content
Data assimilation in conventional meteorological applications uses measurements in conjunction with a physical model. In the case of the ionised region of the upper atmosphere, the ionosphere, assimilation techniques are much...
