On the conic section fitting problem
Adjusted least squares (ALS) estimators for the conic section problem are considered. Consistency of the translation invariant version of ALS estimator is proved. The similarity invariance of the ALS estimator with estimated noise variance is shown.

DESIGN AND ANALYSIS OF LOAD CHARACTERISTICSWITH A LARGE DIMENSION CONIC ULTRASONIC HORN
Jixie qiangdu, 2015 The inherent frequency of longitudinal vibration of a large section of conical horn was deduced by Rayleigh’ s approximate theoretical hypotheses,and the frequency of expression of correction is obtained. Effect of load on a large section of conical horn

Cone spline approximation via fat conic spline fitting
, 2006 Fat conic section and fat conic spline are defined. With well established properties of fat conic splines, the problem of approximating a ruled surface by a tangent smooth cone spline can then be changed as the problem of fitting a plane fat curve by a ...

Conic Section Pencil Given by two Double Points
, 2000 Prikazan je algoritam za određivanje koeficijenata u jednadžbi pramena konika kad je pramen zadan s četiri točke od kojih su dvije dvostruke. Da bi se moglo raditi s neizmjerno dalekim točkama uvedene su homogene koordinate.

Of the rectification of the conic sections [PDF]
Abstracts of the Papers Printed in the Philosophical Transactions of the Royal Society of LondonAbstract This, it is to be observed, is only the first part of a more extensive work, and relates merely to the rectification of the hyperbola. After a few strictures on the necessity of not relaxing in our endeavours to improve the method of fluxions, to which the author asserts few additions have been made since its first discovery
