Electronic structure and electron distribution in an inverse superatom calculated by self-consistent method
(Microelectronics Journal, 1990)
A full self-consistent procedure, applied to an inverse superatom strucuture is described. It is shown, both numerically and theoretically, that the electron concentration is large, but not maximal, the point of maximum ...
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 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 ...
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 ...
Hysteretic Behavior of Elastic-plastic Beams Subjected to Cyclic Bending
(Jugoslovensko društvo za mehaniku - JDM, 1993)
In this paper, Preisach model for hysteresis behavior of elastic-plastic materials is extended to cyclic bending of beams.
Numeričko modeliranje tokova koje karakteriše nagla lokalna promena dubine i protoka / Numerical modelling of discontinuous flows
(Građevinski fakultet Univerziteta u Beogradu, 1998)
Discontinuous flows are the flows in which large gradients arise in both the flow
depth and the discharge due to specific external and/or internal boundary conditions. With
reference to the discontinuity and through the ...
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" ...
