Reconstruction of fiber reinforcement in epoxy-based composite
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear angineering, 2021)
Polymer matrix composites (PMCs) are very attractive materials due to a possibility to achieve versatile properties by combining with ceramic or metal reinforcement in different shapes and sizes. As a result, PMCs have ...
Influence of sintering temperature on the performance of titanium dioxide anode in Dye Sensitized Solar Cells with natural pigment hypericin
(Belgrade : ETRAN Society, 2020)
Dye Sensitized Solar cells (DSSC) are very attractive due to their low cost fabricating methods and used materials. One of the most important parts of the cells is the photoanode. Many semiconducting materials are used for ...
Incorporating a Lowpass Filter into a Very Wide Bandpass Filter to Suppress Harmonics
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear angineering, 2021)
This paper presents an algorithm for suppression of higher harmonics in response of the very wide bandpass filter (WBPF). Lowpass filter (LPF) is incorporated into the very wide bandpass filter to suppress harmonics. The ...

Application of copper electrodeposition processes in visualization of latent fingerprints obtained on various substrates
(Niš, Serbia : RAD Centre, 2022)
In this study, a basic sulfate electrolyte for electrochemical copper deposition and a sulfate electrolyte with additives to improve coating quality were used. It has been shown that for the visualization of latent ...
Povećanje preciznosti izrade 3D štampanih delova primenom iterativne metode
(Uniiverzitet u Beogradu - Mašinski fakultet, 2020)
Veoma veliki porast upotrebe 3D štampe u poslednje dve decenije posledica je niza benefita koje
ova proizvodna tehnologija nudi. U ovom radu analizirano je odstupanje geometrije štampanog modela u
odnosu na CAD model. ...
Impact of relaxation time of activated mixture on ceramics synthesis for electronics purposes / Uticaj vremena relaksacije aktivirane smeše na sintezu keramike za namenu u elektronici
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2020)
Due to its properties, cordierite, 2MgO·2Al2O3·5SiO2, is nowadays an attractive ceramic material
for various applications but with very high sintering temperature. Mechanochemical activation
of the initial components ...
Removal of arsenic(III) oxyanions from wastewater using aminosilane -modified natural and synthetic zeolite
(Croatia : Croatian Zeolites Association, 2021)
Silanization of the natural and synthetic zeolites as well as their use as adsorbents for removing arsenic(III) oxyanions from wastewater are the topic of this paper. Two types of zeolite were used: natural zeolite-clinoptilolite ...
Predikcija brzine na 3D štampaču primenom veštačkih neuronskih mreža
(Uniiverzitet u Beogradu - Mašinski fakultet, 2020)
U ovom radu, izvršena je analiza i predikcija brzina štampe u eksploatacionim uslovima. Postoje
odstupanja zadane brzine na štampaču od proračunate stvarne vrednosti. S tim u vezi, postoji i razlika u
vremenima izrade. ...
