Uticaj zone loma iznad podzemne prostorije na opterećenje konstrukcije sa visećom podgradom / Impact of a failure zone above the underground roadway on rockbolting structure loading
(Institut za ispitivanje materijala, Beograd, 2015)
Research in this article presents development of model of strata interaction with roof support installed in bauxite. The main task of this research is modelling of rock degradation over the surface of underground roadway ...
Stress state around imperfections in welded joints
(Institut za ispitivanje materijala, Beograd, 2015)
Because of their geometry, welded joints can cause a local increase of stress. In the presence of imperfections in welded joints the local stress additionally increases and can lead to the formation of cracks. Cracks are ...
Vibration as deciding parameter during revitalization process for replacing the bucket wheel drive
(Jve Int Ltd, Kaunas, 2015)
After years of excavator`s operation in adverse conditions, one can expect a ratio between the bucket wheel drive and bucket wheel boom which may lead to impairment of structural integrity. Finite elements method is defined ...
An analysis of random mechanical failures of bucket wheel excavator
(Institut za ispitivanje materijala, Beograd, 2015)
In this article random mechanical failures of bucket wheel excavator at open cast mine "Tamnava Zapad" are analysed. Random mechanical failures of mining equipment may represent an important factor in coal production because ...
Zagađenje voda uzrokovano uljima koja potiču od sredstava za čišćenje i odmašćivanje / The degree of water pollution caused by oils from cleaners and degreasers
(Nacionalno naučno društvo za poljoprivrednu tehniku, Novi Sad, 2015)
U nizu tehnoloških procesa kao i za održavanje postrojenja korisie se sredstva za odmašćivanje i čićenje. Najveći deo tih sredstava nakon upotrebe završava u vodama pa moraju biti zadovoljeni uslovi propisani zakonima o ...
Numerical-experimental analysis of the foldable containers strength
(Univ Osijek, Tech Fac, Slavonski Brod, 2015)
This paper describes the numerical and the experimental methodology for analysis of plastic packaging strength characteristics that are representative of its strength in the real life. Numerical analysis was conducted by ...
Istraživanje novonastalih rizika kod pametnih dizalica - Projekat 'SPRINCE' u programu 'SAF€RA' / Emerging risks in smart process industry cranes survey: SAF€RA research project SPRINCE
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2015)
Savremene teorije fokusirane na istraživanje incidenata pokazuju da smanjenje udela ljudskih grešaka ne može da se postigne isključivo korekcijom ponašanja zaposlenih već zahteva izvesne inovacije koje im mogu pomoći u tom ...
Display probability of symbol errors for MQAM on Rician fading channel based on MGF method
(Univerzitet u Beogradu - Fakultet organizacionih nauka, Beograd, i dr., 2015)
We present a new method for calculating the probability of error per symbol (Symbol Error Probability, SEP) of M-ary Quadrature Amplitude Modulation (MQAM) over a slow, flat, identically independently distributed Rician ...
Experimental in-vitro bone cements disintegration with ultrasonic pulsating water jet for revision arthroplasty
(Strojarski Facultet, 2015)
The paper deals with the study of using the selective property of ultrasonic pulsating water jet for the disintegration of the interface created by bone cement between cemented femoral stem and trabecular bone tissue as a ...
Free vibration and buckling analysis of higher order laminated composite plates using the isogeometric approach
(Polish Society of Theoretical and Allied Mechanics, 2015)
This research paper presents a higher order isogeometric laminated composite plate finite element formulation. The isogeometric formulation is based on NURBS (non-uniform rational B-splines) basis functions of varying ...
