The combined method for uncertainty evaluation in electromagnetic radiation measurement
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Electromagnetic radiation of all frequencies represents one of the most common and fastest growing environmental influence. All populations are now exposed to varying degrees of electromagnetic radiation and the levels ...
Procena integriteta zavarenih cevi / Assessment of the integrity of welded pipes
(Inženjersko društvo za koroziju, Beograd, 2014)
Predmet rada je analiza integriteta zavarenih cevi izrađenih od čelika API J55 visokofrekventnim kontaktnim zavarivanjem (VF). Eksperimentalna ispitivanja mehaničkih osobina osnovnog materijala su izvršena na cevima povučenim ...
The failure analysis of the star-separator of an aircraft cannon
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
This paper analyzes the causes of fracture of the double pipe aerial cannon stellate starseparator, which occurred during the fighting plane mission. The linear finite element method (FEM) is used to determine the stresses ...
Projektovanje unutrašnjeg prostora putničkog vozila / Designing interior space for drivers of passenger vehicle
(Savez inženjera i tehničara Srbije, Beograd, 2014)
U radu je dat pregled naših prethodnih istraživanja uz dodatna unapređenja, tako da je dokazana hipoteza da putničko vozilo još uvek nije ergonomski prilagođeno čoveku u dovoljnoj meri, posebno u delu unutrašnjeg prostora ...
Determination of the elements of production cycle time in serial production: the Serbian case
(Canadian Society for Mechanical Engineering, 2014)
A model for the stochastic determination of the elements of production cycle time is proposed and experimentally verified in this survey. The originality of the model as reflected in the idea of using a work sampling model ...
Višeciljna fazi optimizacija veličine i položaja piezoelektričnih aktuatora i senzora za upravljanje vibracijama bazirana na optimizaciji rojem čestica - deo 2 - numerička analiza / Multi-objective fuzzy optimization of sizing and location of piezoelectric actuators and sensors for vibration control based on the particle swarm optimization technique: Part 2: Numerical analysis
(Vojnotehnički institut, Beograd, 2014)
Ovo je drugi deo istraživanja višeciljne fazi optimizacije veličine i položaja piezoelektričnih aktuatora i senzora na tankozidnoj kompozitnoj gredi. Prvi rad je fokusiran na teorijskom modelu optimizacione tehnike za ...
The performance of pip-cascade controler in hvac system
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Primitive controllers used in the early version for HVAC systems, like the on-off (Bang-Bang) controller, are inefficient, inaccurate, unstable, and suffer from high-level mechanical wear. On the other hand, other controllers ...
Impact of choice of stabilized hysteresis loop on the end result of investigation of high-strength low-alloy (hsla) steel on low cycle fatigue
(Faculty of Metallurgy, 2014)
High strength low-alloy steel under low cycle fatigue at a certain level of strain controlled achieve stabilized condition. During the fatigue loading stabilized hysteresis loop is determined, which typical cycle of ...
Superplastic deformation of an x7093 al alloy
(Institute of Metals Technology, 2014)
We have investigated the superplastic deformation mechanism of a powder-metallurgy, high-zinc X7093 Al alloy. The objective was to examine the rate-controlling mechanisms that govern its superplastic deformation. The ...
Techno-economic analysis of heat exchangers with parallel helical tube coils
(Univ Osijek, Tech Fac, Slavonski Brod, 2014)
The paper deals with the investment and exploitation costs for shell and tube heat exchangers with parallel helical tube coils. The most common correlations for estimating prices of shell and tube heat exchangers found in ...
