Dimensional accuracy and experimental investigation on tensile behavior of various 3D printed materials
(The Military Technical Institute, Belgrade, Serbia, 2020)
Additive manufacturing (AM) or 3D printing is becoming very popular in the aerospace and defense industry
because of its ability to manufacture complex parts at a low price. Fused deposition modeling (FDM) is one of the ...
Theoretical Study of σ-hole Bonding between Selenium Atoms in Crystal Structures of Organoselenium Compounds
(Stellenbosch, South Africa : Department of Chemical and Polymer Science at Stellenbosch University, 2020)
Non-covalent interactions involving selenium atoms are of great importance in chemistry and biochemistry due to the prominent role of selenium-containing molecules (like Se-antioxidants and selenoenzymes) in different ...
Fluorination as a Driving Force in Crystal Structures
(Commission on Quantum Crystallography of IUCr, 2020)
The results of the crystallographic analysis in combination with quantum chemical calculations have
shown that fluorination of organic compounds causes an increase in the proton-donating ability and a
decrease in the ...
Implementacija aditivne proizvodnje u Lean koncept / Implementation of additive manufacturing in the lean concept
(Uniiverzitet u Beogradu - Mašinski fakultet, 2020)
U ovom radu prikazan je značaj aditivne proizvodnje u okviru Lean koncepta. Koncept definiše sedam
vrsta proizvodnog otpada, dok Lean proizvodnja podrazumeva uklanjanje tog otpada. Aditivna proizvodnja

Cerium-cysteine complex inhibitor for aluminium alloy AA7075-T6
(Belgrade : Military Technical Institute, 2020)
Aluminium AA7075 alloy with its low density and good mechanical properties, widely responds to the
requirements of aerospace, navy, and defense industries. However, corrosion is the most common problem that affects
the ...
Instability region in models of nonlinear reaction systems. The Stoichiometric Network Analysis
(Serbian academy of nonlinear sciences, 2020)
Stability analysis of reaction systems is described by the application of the Stoichiometric Network Analysis to the three-variable-autocatalator. Although simple, this model is complex enough to describe complex forms of ...
Laser techniques and couplings with other techniques in contemporary problem solving in theory and practice
(Academy of Sciences and Arts of the Republic of Srpska / Академија наука и умјетности Републике Српске, 2020)
Problems of today, pro et contra of new breakthroughs in high frequencies and pandemics, seem to have called for even more complex correlations and couplings of the fields: science, empiria (practice), mass-media in mastering ...
Forced periodic reactor operation: Analysis of process and forcing parameters exploiting the nonlinear frequency response method
(WILEY-VCH, 2020)
Continuous chemical reactors are mostly operated under steady-state conditions. However, theoretical studies reveal that forced periodic operation (FPO) can lead to better performance. To predict and optimize FPO, the ...
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. ...
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. ...
