DRM-MD approach for bound electron states in semiconductor nano-wires
(Boundary Elements and Other Mesh Reduction Methods Xxix, 2007)
Using the boundary element dual reciprocity method-multi domain (DRM-MD), bound electron states and the corresponding wave functions in semiconductor quantum wires embedded in a matrix were considered. The single circular ...
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 ...
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 ...
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 ...
