Izračunavanje verovatnoće greške po simbolu na bazi MGF metode korišćenjem Rician feding kanala za MFSK modulaciju / Calculating the probability of error per symbol on the basis of MGF method using Rician fading for MFSK
(Savez inženjera i tehničara Srbije, Beograd, 2014)
U ovom radu se analizira verovatnoća greške po simbolu za M-arnu ne-koherentnu frekvencijsku modulaciju (M-ary Frequency Shift Keying, MFSK) signala u ambijentu frekvencijsko-neselektivnog sporog Rician fadinga i prijemnika ...
Potential for improvement of comfort parameters in off-road vehicles of Serbian armed forces
(Strojarski Facultet, 2014)
The paper presents the comparative results of comfort parameter testing inside the cabin of Land Rover Defender off-road vehicles. The measurements were carried out on two vehicle models -110 GS Hard Top and 110 GS Soft ...
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 ...
Numerical modelling of crack propagation in friction stir welded joint made of aluminium alloy
(Elsevier Science Bv, Amsterdam, 2014)
In this work, fatigue crack propagation in thin-walled aluminium alloy structure with two friction stir welded (FSW) joints has been numerically modelled. Crack propagation in unstiffened part of the structure between two ...
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 ...

(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 ...
