An application of Groebner bases to planarity of intersection of surfaces
(Univerzitet u Nišu - Prirodno-matematički fakultet - Departmant za matematiku i informatiku, Niš, 2009)
In this paper we use Groebner bases theory in order to determine planarity of intersections of two algebraic surfaces in R3. We specially considered plane sections of certain type of conoid which has a cubic egg curve as ...
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 ...
Istraživanje geometrijskog predznanja studenata prve godine građevinskog fakulteta u Beogradu
(Novi Sad: Fakultet tehničkih nauka, 2006)
Na osnovu testa poznavanja elementarne geometrije koji je sproveden na početku šk. 2004/05 god, sa studentima građevinskog i geodetskog smera Građevinskog fakulteta u Beogradu izvršena je analiza ostvarenih rezultata. ...
Crtanje pravilnih poliedara u jednoj ortogonalnoj projekciji
(Jugoslovensko udruženje za nacrtnu geometriju i inženjersku grafiku, 2002)
Dovoljno je da samo u jednoj ortogonalnoj projekciji poznajemo 3 tačke jedne strane nekog pravilnog poliedra da bismo mogli da nacrtamo ostatak tela. Kako su strane pravilnih poliedara identični, pravilni poligoni, oko ...
Common right factor of skew polynomials / The Resultants of Non-Commutative Polynomials
(Matematički vesnik, 2008)
Let R = K[x; σ] be a skew polynomial ring over a division ring K. Necessary and sufficient condition under which common right factor of two skew polynomials exists is estab-lished. It is shown that the existence of common ...
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 ...
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 ...
