Prostorna interpretacija Hugelschaffer-ove konstrukcije jajaste krive
(Niš: Faculty of Architecture and Civil Engineering in Niš; Serbian Society for Geometry and Graphics (SUGIG), 2008)
Konstrukcija jajaste kubne krive Hügelschäffer-ovom metodom, zasniva se na konstrukciji elipse metodom koncentričnih krugova različitih radijusa, a i b, koji odgovaraju parametrima elipse. Načinjen je pokušaj da se prostornom ...
Konstruktivna obrada hiperboličke spirale kao centralne projekcije cilindrične zavojnice
(Novi Sad: Fakultet tehničkih nauka, 2006)
Centralna projekcija cilindrične zavojnice jeste ravna transcedentna kriva, u najopštijem slučaju. U određenim slučajevima, ta kriva će biti upravo spiralna kriva. U specijalnom slučaju, kada se osovina cilindra poklapa ...
Univalency and convolution results associated with confluent hypergeometric functions
(Houston Journal of Mathematics, 2009)
Given the confluent hypergeometric functions Φ(a; c; z), we
place conditions on a and c to guarantee that zΦ(a; c; z) will be in two sub-
classes of univalent functions. In addition, we obtain conditions to obtain
some ...
Two methods of quantum well profile optimization for maximal nonlinear optical susceptibilities
(Physical Review B, 2001)
Two different approaches for the optimization of the quantum well profile are proposed and discussed. One is the multiparameter procedure, based on the inverse spectral theory (IST) and supersymmetric quantum mechanics ...
Multiparameter optimization of optical nonlinearities in semiconductor quantum wells by supersymmetric quantum mechanics
(Physics Letters A, 2001)
The multiparameter procedure of semiconductor quantum well profile optimization, using the supersymmetric quantum mechanics, is described and explored. The method generates families of isospectral potentials that depend ...
About planar sections of a type of egg curve based conoid
(Novi Sad: Faculty of Sciences, University of Novi Sad - Department of Mathematics and Informatics, 2009)
Starting from a type of conoid which is based on a cubic egg curve obtained by Hügelschäffer’s construction, it is considered a possible occurrence of related type of conoid, which would include conic curve as a part of ...
Polynomial Interpolation Problem for Skew Polynomials
(Applicable Analysis and Discrete Mathematics, 2007)
Let R = K[x;δ] be a skew polynomial ring over a division ring K. We introduce the notion of derivatives of skew polynomial at scalars. An analogous definition of derivatives of commutative polynomials from K[x] as a function ...
