Optimization of multistage turbines using a through-flow code
(Professional Engineering Publishing Ltd, Bury St Edmunds, 2001)
Fast and accurate flow calculation and performance prediction of multistage axial flow turbines at design and off-design conditions were performed using a compressible steady state inviscid through-flow code with high ...
Two-component propellant grain for rocket motor combustion analysis and geometric optimization
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
The paper considers utilization of rocket motor propellant grains that consist of two propellants. The idea is to achieve approximately neutral burning using an outer surface inhibited cylindrical shape and complex contact ...
Kriterijum efikasnosti i optimizacija mase fragmenta projektila parčadnog dejstva / Efficiency criterion and optimization of fragment mass in fragmentation projectiles
(Univerzitet odbrane u Beogradu - Institut za naučne informacije, Beograd, 2003)
U radu se razmatra problem optimizacije mase parčadi koja nastaju fragmentacijom projektila parčadnog dejstva. Pokazano je da optimalna masa parčeta prvenstveno zavisi od njegovih kinetičkih karakteristika na cilju kao i ...
Optimisation of tensile stress of poly(lactic acid) 3D printed materials using response surface methodology
(Belgrade : Balkan Scientific Centre, 2022)
Three-dimensional printed plastic products developed through fused deposition modelling (FDM) take long-term mechanical loading in most industrial prototypes. This article focuses on the impact of the 3D printing parameters, ...
Upravljanje antropomorfnom robotskom rukom koristeći genetičke algoritme
(Beograd : Jugoslovensko društvo za mehaniku, 1997)
In this paper it is treated control of an anthropomorphic robot arm (ARA) with three of freedom. Analysis of multijoint coordination in humans is an important source of information for synthesis of dynamic patterns in ...

(Kraljevo : Faculty of Mechanical and Civil Engineering, 2011)
The use of truss constructions is frequent in mechanical engineering. This paper describes the procedures of construction and optimization for truss constrictions at the example of roof structure of the Hall. Frame ...
An Approach to Optimization of Warranty Policy – a Case Study
(Serbian Maintenance Association DOTS / European Federation of national Maintenance Societies EFNMS, 2012)
Product development risk increases more and more every day and one of the factors that affect this risk is product warranty. Warranty is a powerful marketing instrument for the manufacturer and at the same time a good ...
Numerical Investigation and Optimization of a Morphing Airfoil Designed for Lower Reynolds Number
(MDPI, 2024)
A novel concept of morphing airfoils, capable of changing camber and thickness, is proposed. A variable airfoil shape, defined by six input parameters, is achieved by allowing the three spinal points (at fixed axial ...
Optimizacija parametara tehničkih rešenja za mašinsko branje koštičavog i jagodičastog voća / Optimization of parameter of technical solutions for mechanical harvest of stone and berry fruit
(Univerzitet u Beogradu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Beograd, 2009)
Mašinko branje voća, prvenstveno koštićavog i jagodičastog voća predstavlja zahtevan zadatak zbog mogućeg oštećenja plodova pri kontaktu plodova sa granama, delovima mašine (uređaja), kao i pri padu na podlogu. U radu su ...
