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 ...
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 ...
An approach to stimulation of dual drainage
(Elsevier Science LtdExeter, 1999)
The paper presents the development in the field of urban drainage modelling known as dual drainage - an approach to rainfall runoff simulation in which the numerical model takes into account not only the flow through the ...
MAC1MK
(Građevinski fakultet, Univerziteta u Beogradu, 1993)
Softver (program) MAC1MK namenjen je za proračun linijskog naglo i blago promenljivog neustaljenog tecenja u otvorenim tokovima. Koristi eksplicitnu shemu razdvojenih operatora MacCormack za sve profile razmatrane deonice ...
Experimental verification of the MacCormack numerical scheme
(Advances in Engineering Software, 1995)
One-dimensional and two-dimensional dam-break flow experiments, that had been performed on two original laboratory installations, were numerically simulated using the MacCormack explicit computational scheme. Accuracy and ...
