dissertation is ...
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 ...
Metode za rešavanje problema triangulacije poligona i njihova implementacija / Methods for solving the polygon triangulation problem and their implementation
(Универзитет у Нишу, Природно-математички факултет, 2013)
The dissertation includes new methods in order to increase the speed of generating polygon triangulation. The first method is based on the process of decomposing the Catalan numbers. The second method is based on the ...

(Универзитет у Нишу, Природно-математички факултет, 16-06-2017)
In this thesis, we analyzed some of the coherent effects – electromagnetically
induced transparency and spontaneously generated coherence – that can
appear in the interaction of the confined hydrogen atom with laser ...
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 ...
