Modeliranje naglo promenljivih otvorenih tokova / Modelling of free-surface discontinuous flows
(Zadužbina Andrejević, 1999)
Osnovna karakteristika naglo promenljivih otvorenih tokova je postojanje velikih gradijenata dubine i protoka. Ove nagle lokalne promene osnovnih veličina toka nastaju kao posledica specifičnih graničnih uslova (spoljašnjih ...
Continuum electron wavefunction shifts in semiconductor quantum dot
(Solid State Phenomena, 1998)
In this paper, the mathematical model for electron wavefunction shifts in the continuum part of the electronic spectrum of a GaAs-Al0.3Ga0.7As based semiconductor quantum dot (QD) is presented. The electron states in the ...
GAMOD
(Građevinski fakultet, Univerziteta u Beogradu, 1994)
Softver (program) GAMOD namenjen je proračunu gubitaka vode usled infiltracije. Zasniva se na Grin-Emptovom nelinearnom modelu infiltracije.
Influence of the self-consistent potential on absorption cross section in semiconductor quantum dot
(Solid State Phenomena, 1998)
In this paper the intersubband optical absorption cross sections are calculated for spherically symmetric semiconductor quantum dot (QD), made of GaAs-Al0.3Ga0.7As with the influence of the accumulated charge in the well ...
Bound-continuum intersubband transition based optical nonlinearities in semiconductor quantum wells
(Solid State Phenomena, 1998)
The possibility is explored of obtaining resonantly enhanced nonlinear optical susceptibilities in semiconductor quantum wells with two bound states and the resonant state in continuum as the third state. This would ...
Intersubband resonant third harmonic generation in asymmetric semiconductor quantum wells
(Solid State Phenomena, 1998)
Possibilities for the systematic optimization of step-graded ternary alloys based quantum wells, in respect to third order nonlinear susceptibility ar resonance, are discussed. The use of this method is exemplified on the ...
Preisach Model for Cyclic Bending of Elastoplastic Beams
(Elsevier, 1996)
In the present paper, the Preisach model, already successfully implemented for the problem of axially loaded members, has been extended to the cyclic bending of elasto-plastic beams. Starting from Hooke's and St. Venant's ...
CAMPREL: A New Adaptive Conformal Cartographic Projection
(American Congress on Surveying and Mapping, 1997)
The theoretical basis of CAMPREL is discussed. Previously derived partial, differential second- order equations describing the conformal mapping of a rotational ellepsoid onto a plane, and the contour conditions formulated ...
A simple solution for a crack reinforced by bands
(Engineering Fracture Mechanics, 1989)
The paper represents a simple approximate solution for a crack reinforced by elastic bands (springs). The obtained results for the stress intensity factor are compared with the exact solutions for the case of infinitely ...
A contribution to the analysis of box beams with deformable cross section
(Journal of Constructional Steel Research, 1988)
This paper compares the simplified theory of thin-walled box beams with deformable cross section given by Sedlacek with the more accurate approach proposed by Kollbrunner and Hajdin. Single-cell, simply supported box girders ...
