Informacioni sistem za osmatranje i praćenje sistema 'brana - akumulacija' / Information System for Observation and Monitoring the 'Dam - Reservoir' System
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, 1998)
U radu se razmatra problematika osmatranja i praćenja sistema 'brana - akumulacija', sa posebnim osvrtom na praćenje i ocenu kvaliteta vode u akumulacijama. Analiza sadašnjeg stanja pokazala je da opisana problematika kod ...
Problemi evakuacionih organa brane "Grlište" / Evacuation Structures for the Grlište Dam
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, 1998)
Nasuta brana "Grlište", izgrađena od kamenog nabačaja sa uzvodnim betonskim ekranom, nalazi se uzvodno od sela Grlište, a služi za snabdevanje vodom grada Zaječara. Evakuacija velikih vode ostvaruje se "baterijom šahtnih ...
Historical rainfall for urban storm drainage design
(Water Science and Technology, 1998)
Traditional design method for urban drainage systems is based on design storms and its major drawback is that frequencies of peak flows in the system are considered equal to frequencies of design storms. An alternative is ...
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 ...
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 ...
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 ...
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 ...
