Opšti tip stabilnosti stohastičkih funkcionalnih diferencijalnih jednačina / General decay stability of stochastic functional differential equations
(Универзитет у Нишу, Природно-математички факултет, 21-07-2014)
In this thesis, pth moment and almost sure stability on a general decay rate for
several types of stochastic functional differential equations were studied. By applying
Razumikhin method and Lyapunov method stability ...
Izračunavanje Hankelove transformacije nizova / Computation of the Hankel transform of sequences
(Универзитет у Нишу, Природно-математички факултет, 29-05-2014)
Hankel determinants (persymmetric, Turan determinants) have
been studying for a long time. Until now, many different
methods for computation of Hankel determinants have been
constructed. Also, those methods are applied on ...
Hemometrijska analiza rezultata hemijskih i bioloških istraživanja farmakološki značajnih biljaka / Chemometric analysis of chemical and biological studies of pharmacologically important plants
(Универзитет у Нишу, Природно-математички факултет, 30-09-2014)
Plants synthesize primary and secondary metabolites from simple molecules, among wich inorganic compounds are of great importance. Examining the extractability and solubility of the soil elements helps us explicate the ...
Vremenski nizovi sa negativnim celobrojnom vrednostima generisani zavisnim brojačkim nizovima / Time series with non-negative integer values based on dependent counting series
(Универзитет у Нишу, Природно-математички факултет, 24-12-2014)
New generalized thinning operators based on Bernoulli
sequences of dependent random variables are presented In
this thesis. Using these operators autoregressive models of
the first order with non-negative integer values ...
Strukturna karakterizacija CaMnOз nanoprahova dopiranih itrijumom i teorijsko modelovanje stabilnosti perovskitske strukture / Structural characterization of the yttrium doped camno3 nanopowders and theoretical modelling of the perovskite structure stability
(Универзитет у Нишу, Природно-математички факултет, 24-12-2014)
In the first part of dissertation structural, microstructural and phase analysis of
the nanopowders with the general formula Ca1-xYxMnO3 (0 ≤ x ≤ 1) were performed
using XRPD diffraction technique and Rietveld refinement. ...
Sinteza biodizela na aktiviranom katalizatoru na bazi CaO: optimizacija procesnih parametara i efekti korišćenja biodizela / Synthesis of biodiesel over activated cao-based catalyst: optimisation of process parameters and effects of using biodiesel
(Универзитет у Нишу, Природно-математички факултет, 25-12-2014)
The influence of the physicochemical properties of a series of
CaO catalysts activated at different temperatures on the
biodiesel production was investigated. These catalysts show
dissimilar yields in the transesterification ...
Permutacije sa ograničenjima / Restricted permutations
(Универзитет у Нишу, Природно-математички факултет, 21-07-2014)
In this thesis we study different methods of counting a large number of
combinatorial objects: permutations, variations, combinations, subsets, with
some additional restrictions. We have developed a completely new method
for ...
Uticaj dijamagnetnih dvovalentnih jona metala na autooksidaciju vicinalnih trihidroksilnih fenolnih jedinjenja u vodenim rastvorima / The influence of divalent diamagnetic metal ions on vicinal trihydroxy phenolic compounds autoxidation in aqueous solutions
(Универзитет у Нишу, Природно-математички факултет, 21-07-2014)
In this dissertation the influence of divalent diamagnetic
metal ions (Mg(II), Ca(II), Sr(II), Ba(II), Zn(II), Cd(II) and Pb(II))
on vicinal trihydroxy phenolic compounds autoxidation in
aqueous solutions was examined. ...
