Approximation of conic sections by weighted Lupaş post-quantum Bézier curves
Demonstratio Mathematica, 2022 This paper deals with weighted Lupaş post-quantum Bernstein blending functions and Bézier curves constructed with the help of bases via (p,q)\left(p,q)-integers. These blending functions form normalized totally positive bases.

Discrete characterizations of wave front sets of Fourier-Lebesgue and quasianalytic type [PDF]
, 2016 We obtain discrete characterizations of wave front sets of Fourier-Lebesgue and quasianalytic type. It is shown that the microlocal properties of an ultradistribution can be obtained by sampling the Fourier transforms of its localizations over a lattice ...

Some incidence theorems and integrable discrete equations
, 2004 Several incidence theorems of planar projective geometry are considered. It is demonstrated that generalizations of Pascal theorem due to M\"obius give rise to double cross-ratio equation and Hietarinta equation.

, 2015 In the manner of Apollonius of Perga, but hardly any modern book, we investigate conic sections as such. We thus discover why Apollonius calls a conic section a parabola, an hyperbola, or an ellipse; and we discover the meanings of the terms abscissa and

THE HYPERBOLOID OF REVOLUTION OF ONE NAPPE A RULED SURFACE GENERATING CONICS
Journal of Industrial Design and Engineering Graphics, 2013 The paper intends to underline the property of the hyperboloid of revolution of one nappe to generate on its surface, when it is cut by a plane, the three known conics (ellipse, hyperbola and parabola).Cutting this surface by a plane, we find the ...

PENGEMBANGAN MODUL IRISAN KERUCUT BERBANTUAN GEOGEBRA
Aksioma: Jurnal Program Studi Pendidikan Matematika, 2017 The aim of this research was to develop a conic section modul. The modul used GeoGebra in presenting material. This research used development model of Plomp, with three step including preliminary research, prototyping stage and assesment phase.

Molecular Oncology, EarlyView.Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Area Properties of Strictly Convex Curves
Mathematics, 2019 We study functions defined in the plane E 2 in which level curves are strictly convex, and investigate area properties of regions cut off by chords on the level curves.

Math Horizons, 2021 Circles, ellipses, parabolas, and hyperbolas are called conic sections because each of these curves arises as the boundary of a slice of a cone. Imagine slicing a solid cone of clay.
