Resonantly enhanced bound-continuum intersubband second harmonic generation in optimized asymmetric semiconductor quantum wells
(Physica E: Low-dimensional Systems and Nanostructures, 1999)
A systematic procedure applied to a step-asymmetric quantum well in order to maximize intersubband bound–continuum second-order susceptibility is described. The possibility is explored of obtaining resonantly enhanced ...
Modeliranje kvaliteta vode u jezerima i akumulacijama / Mathematical Modelling of Water Quality in Lakes and Reservoirs
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, 1994)
U radu je obrađena problematika matematičkog modeliranja ekoloških procesa u jezerima i akumulacijama. Prikazani su principi matematičkog modeliranja najbitnijih fizičkih, hemijskih i bioloških procesa koji utiču na kvalitet ...
Otkrivanje obrtnih konuseva zadatih ravnim presekom po elipsi i pravcem ravni kružnog preseka
(Jugoslovensko udruženje za nacrtnu geometriju i inženjersku grafiku, 1997)
Neka je poznata proizvoljna elipsa e i položaj ravni P kružnog preseka konusa. Na pravoj p ravni P, koja prolazi centrom elipse, postoji cirkularna involucija.kojom su određeni kružni preseci čitavog pramena konuseva koji ...
The self-consistent electronic structure of spherical semiconductor quantum dots including bound and free states
(Solid State Communications, 1997)
A self-consistent procedure for calculating the energy structure, wave functions and charge distribution in spherically symmetric semiconductor quantum dots is presented, that takes account of both bound and free electron ...
Modeliranje abiotičkih i biotičkih procesa u akvatorijama vodoprivrednih sistema / Modeling of Abiotic and Biotic Processes in Water Storage Reservoirs
(Institut "Mihajlo Pupin", Beograd, 1998)
Radi praćenja procesa koji se odvijaju u akvatorijama vodoprivrednih sistema (akumulacijama, retenzijama) neophodno je modeliranje abiotičkih i biotičkih procesa kojima se prognoziraju akcije, reakcije i koakcije na relaciji ...
Operatori ekspertnog sistema za ocenu bezbednosti brana / Operators of an Expert System for Safety Evaluation of Dams
(Univerzitet u Beogradu, Ekonomski fakultet, 1996)
U radu je prikazan specifičan i originalan način prevazilaženja odredjenih teškoća, koje se odnose na konkretne uslove vezane za stanje u oblasti bez-bednosti brana u Srbiji, koji ovu materiju svrstavaju u tzv. "fuzzy" ...
Affine Conform Planes as the Special Cases of General Collinear Planes
(Cracow University of Technology, Cracow, 1996., 1996)
General collinear planes whose double straight line is at infinity are affine collinear planes.
Affine collinear planes whose double points of collocation on the infinitely distant double straight line are the absolute ...
The Geometrical Loci of Laguerre’s points of Perspective elliptical Involuted Sets
(Cracow University of Technology, Cracow, 1996., 1996)
This paper discloses the proof, based on the space restitution, that geometrical loci of Laguerre's points of perspective elliptical involuted sets represent two circles. The exposed theorem is a contribution to the theory ...
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 ...
