Enhancing UCA-ESPRIT for non-circular sources
2007 9th International Symposium on Signal Processing and Its Applications, 2007UCA-ESPRIT is a subspace-based algorithm that is applicable to uniform circular arrays (UCAs). It is a closed-form algorithm that provides automatically paired estimates of the azimuth and elevation angles of multiple farfield plane waves incident on the circular array. Work (M. Haardt and F.

Non-circular cross-section stellarators
Nuclear Fusion, 1976The magnetic surfaces and rotational transform of a stellarator with low poloidal-field wave number and elliptical minor cross-section have been computed numerically by utilizing a predictor-corrector code. The surfaces exhibit stagnation points the positions of which are related to the aspect ratio of the ellipse and the l-number of the configuration.

Non‐circular, non‐well‐founded set universes
Mathematical Logic Quarterly, 1993AbstractWe show that there are universes of sets which contain descending ϵ‐sequences of length α for every ordinal α, though they do not contain any ϵ‐cycle. It is also shown that there is no set universe containing a descending ϵ‐sequence of length On. MSC: 03E30; 03E65.

Non-circular wheels: Reuleaux and squares
Physics Education, 2011Circular wheels are so familiar on vehicles of all types that it is seldom realized that alternatives do exist. This short non-mathematical article describes Reuleaux and square wheels that, rolling along appropriate tracks, can maintain a moving platform at a constant height.

Sorption and desorption in non-circular cylinders
Transactions of the Faraday Society, 1970The sorption-desorption properties of cylinders with polygonal and rectangular cross-sections are examined. Emphasis is placed on the errors which might be incurred by the use of the commonly-adopted circular-cylinder assumption in the pore size distribution analysis of such materials.
