Numerical prediction of nucleate pool boiling heat transfer coefficient under high heat fluxes
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
This paper presents computational fluid dynamics approach to prediction of the heat transfer coefficient for nucleate pool boiling under high heat fluxes. The 3-D numerical simulations of the atmospheric saturated pool ...
Effectiveness of quality management factors and differences in total factor productivity
(Inderscience Publishers, 2016)
Quality management (QM) programme often is not a measure of high organisational effectiveness and business performances, so it is of interest to explore the relation between QM critical factors and total factor productivity ...
Rapid multidisciplinary, multi-objective optimization of composite horizontal-axis wind turbine blade
(Institute of Electrical and Electronics Engineers Inc., 2016)
A fast and efficient process of integrated design (both aerodynamic and structural) of a composite horizontal-axis wind turbine (HAWT) blade is presented. Multi-objective optimization using a nondeterministic particle swarm ...
Statistical correlation between vibration characteristics, surface temperatures and service life of rolling bearings - artificially contaminated by open pit coal mine debris particles
(Elsevier Science Bv, Amsterdam, 2016)
Nowadays, two most often used methods for rolling bearings condition monitoring are thermographic inspection and vibrodiagno stic. However, analysis of the relevant literature has shown that so far there is no established ...
Metode za izračunavanje temperatura predgrevanja pri zavarivanju čelika povišene i visoke čvrstoće / Methods for calculating the preheat temperature welding the high strength steels
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2016)
Predgrevanjem čelika se smanjuje brzina hlađenja zone uticaja toplote, čime se izbegava pojava struktura sklonih nastanku hladnih prslina. Sa druge strane suviše mala brzina hlađenja, u ovoj zoni, dovodi do porasta metalnog ...
Analysis of the brachistochronic motion of a variable mass nonholonomic mechanical system
(Srpsko društvo za mehaniku, Beograd, 2016)
The paper considers the brachistochronic motion of a variable mass nonholonomic mechanical system [3] in a horizontal plane, between two specified positions. Variable mass particles are interconnected by a lightweight ...
Transportna svojstva pentacena, heksacena i njihovih BN analoga / Transport properties of pentacene, hexacene and their BN analogues
(Contemporary materials, 2016)
Istraživali smo transportna svojstva predstavnika acena, pentacena i heksacena i upoređivali ih sa transportnim svojstvima njihovih BN analognih struktura. Prelaz naelektrisanja sa jedne na drugu strukturu istražen je preko ...
Monitoring tribomehaničkog sistema preko sredstva za podmazivanje / Monitoring of tribomehanical systems through lubrication agents
(Nacionalno naučno društvo za poljoprivrednu tehniku, Novi Sad, 2016)
Monitoring stanja tribomehaničkih sistema ima veoma veliki značaj u razvoju teorije i prakse o trenju i habanju kao i teoriji podmazivanja. U savremenim tribomehaničkim sistemima se primenjuju različite fizičko hemijske i ...
Uticaj poremećaja u procesu ubrizgavanja goriva na radne procese u cilindrima dizel-motora / Vozdejstvie razrušenija v processe vpryska topliva na rabočie processy v cilindrah dizel'nogo dvigatelja / (francuski) Effet des perturbations dans le processus de l'injection de carburant sur le processus de travail chez les cylindres des moteurs diesel
(Vojnotehnički institut, Beograd, 2016)
Neujednačenost radnih procesa u cilindrima dizel-motora se može desiti iz više razloga. Dva najuticajnija faktora na ovu pojavu, a koji se odnose na poremećaje u procesu ubrizgavanja goriva, su: poremećaji u pogledu trenutnog ...
The evolution of the double-horse chariots from the bronze age to the Hellenistic times
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2016)
Light chariots with spoked wheels were developed initially in Syria or Northern Mesopotamia at about the beginning of the 2nd millennium B.C. and quickly propagated all over Middle East. The two-wheeled horsedrawn chariot ...
