	Niels Henrik Abel Summary
		Abel was born in Finnöy, on the southwestern coast of Norway, on August 5, 1802.
		Abel's father was appointed to a new parish in 1804, and the family moved to the town of Gjerstad, in southern Norway.
		Abel obliged, providing Crelle with a manuscript that described his proof that an algebraic solution to the general equation of the fifth and higher degrees was impossible.

	Abel Gance (1889-1981)
		Abel was raised by his maternal grandparents in the village of Commentry until he was eight.
		Abel Gance was a giant of cinema art, a genius whose artistic courage and humanist vision created masterpieces that inspired many other directors, from his silent film contemporaries in the 1920s to the French Nouvelle Vague of the 1950s and 1960s.
		Expressing these conflicts in his work, Abel Gance created films that are unique and timeless in their dynamic portrayal of the triumphs and dilemmas of humanity in its search for the ideal.

	Biography of Niels Henrick Abel
		Abel was unable to meet his financial needs so he had to rely on grants from the University, gifts from his math professors, and tutoring positions to help his family.
		Abel sent a paper on the quintic equation to Gauss, who was at that time the leading mathematician, but Gauss thought that it was "another of those monstrosities" and he never even read it.
		Abel was able to get his paper on elliptic function and integrals which included Abel's Theorem, presented to the French Academy of Sciences, that meant that if his work was accepted he would get a lot of recognition.

		Ionospheric profiling using the Abel inversion technique In the mid 1960’s, a group at the Stanford University and the Jet Propulsion Laboratory introduced the Abel inversion technique [Fjeldbo and Eshelman, 1969; Fjeldbo et al., 1971] to recover precise refractivity profiles from the observed bending angles induced by the atmosphere.
		The improved Abel inversion process through “compensated” TEC values The Microlab-1 spacecraft was equipped with single antenna that tracked all 24 GPS satellites in view of rising behind the Earth’s atmosphere and ionosphere at an angle less than ~60 degrees of the occultation plane out of the LEO orbital plane.
		In the simplest Abel inversion process the ionospheric electron density is assumed locally spherical symmetry and to be a function of the impact distance only as ne0(a) during each occultation measurement.

	DTA 1997 \| Elizabeth Abel
		Elizabeth Abel, Associate Professor of English, who specializes in feminist theory and modern fiction, is able to transform a classroom "into a genuinely open intellectual space," according to one of her colleagues.
		Abel joined the Department of English in 1982.
		When I encouraged her to work with those connections rather than trying to suppress them, she wrote an extraordinary thesis on photography's relation to time, death, and emotional instability, a thesis that drew connections never made before.

		Treating the narrow bandwidth trace and its quadrature trace as the real and imaginary parts of a "complex" trace permits the "instantaneous" amplitude of each narrow bandwidth trace to be compute.
		The result, upon inverse Fourier transforming, is that nfilt traces are created, with each trace representing a different frequency band in the original data.
		This is not a wavelet transform, but rather a redundant frame representation.

		Once this transform has been applied, the text can be compressed with a combination of Move to Front encoding followed by an entropy encoder.
		Transform is a BWT compressor written by Michael Bone.
		Implementing the BWT transform is nice and simple, but what you do with the transformed data is where all the action is. Traditionally, we use Move To Front followed by an entropy encoder.

		With a change of variables the Abel transform gives the projection of a 2-D distribution with circular symmetry.
		Thus the Abel inversion formula allows one to determine the radial dependence of such a distribution from its projection.
		The MAP method yields a smooth solution in regions where the signal-to-noise ratio is low while maintaining good spatial resolution in regions where it is high.

		Vesselin Drensky has posted a new preprint, "Invariants of unipotent transformations acting on noetherian relatively free algebras", to the arXiv.
		Abstract: The classical theorem of Weitzenboeck states that the algebra of invariants of a single unipotent transformation $g$ in $GL_m(K)$ acting on the polynomial algebra $K[x_1,...,x_m]$ over a field $K$ of characteristic 0 is finitely generated.
		Recently the author and C.K. Gupta have started the study of the algebra of $g$-invariants of relatively free algebras of rank $m$ in varieties of associative algebras.

		------------------------------------------------------ Abel's first notable work was a proof of the impossibility of solving the quintic equation by radicals (see Abel-Ruffini theorem.) This investigation was first published in 1824 in abstruse and difficult form, and afterwards (1826) more elaborately in the first volume of Crelle's Journal.

	Improvement of ionospheric electron density estimation with GPSMET occultations using Abel inversion and VTEC ...
		As it is known, the Abel transform has been proven to be a useful tool that offers the possibility to obtain vertical description of ionospheric electron density (among other neutral atmosphere parameters) through inversion of Global Positioning System (GPS) observations gathered by Low Earth Orbiters (LEO).
		This work is focused on extending the application of this technique to GPSMET data considering Vertical Total Electron Content.
		This approach shows how this information improves the results obtained in electron densities with respect to the traditional approach of Abel inversion that assumes spherical symmetry.

		I was wondering if anybody knew of any visual c++ code to transform an array of values into an array of radial densities (inverse Abel transform).
		Although I have never heard of this transform before, it sounds like an extremely easy thing to do.
		Iterate all elements of your array, for each element measure its "distance" from the center of the array and let the element value contribute to the "nearest" element in the vector of radial densities.
