Lost production costs of the overburden excavation system caused by rubber belt failure
(Polish Academy of Sciences Branch Lublin, 2012)
In this paper the average malfunction costs (lost production) of the overburden excavation system on the Tamnava - East field open-pit mine caused by the failure of belt conveyor rubber belts which work on the bucket wheel ...
Optimum design of thin-walled i-beam subjected to stress constraint
(Polish Society of Theoretical and Allied Mechanics, 2012)
This paper deals with the problem of optimization of a thin-walled open section I-beam loaded in a complex way, subjected to the bending, torsion and constrained torsion. A general case of bending moments about two centroidal ...
A model for gear shifting optimization in motor vehicles
(Transactions of Famena, 2012)
This paper presents an implemented idea for gear shifting optimization with the aim of fuel consumption minimization. A new combined theoretical and experimental approach has been developed using the On-Board Diagnostic ...
Photoinduced processes, radiation interaction with material and damages - material hardness
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2015)
Photo and nuclear radiation induced processes are considered through the interaction of radiation with semiconducting, metallic and other materials, including the scintillator materials. The improvement of component ...
Fruit flow calculation on the rotating sizing machines
(Strojarski Facultet, 2014)
This paper analyzes theoretically the motion and flow of eight fruit types, along rotating sizing machines. It starts from differential equation of fruit motion on a rotating disk of the sizing machine. A universal method ...
Improving structure dynamic behaviour using a reanalysis procedures technique
(Univ Osijek, Tech Fac, Slavonski Brod, 2013)
The present paper deals with the problem of improving dynamic characteristics for a sub-structure of bucket wheel excavator. The procedure is concerned with the analysis of the distribution of potential and kinetic energy ...
Effects of operation temperature on thermal expansion and main parameters of radial ball bearings
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2015)
The research of influence of operation temperature on the thermal expansion and main parameters of radial ball bearings is presented in this paper. The main bearing parameters are identified in accordance with the increasing ...
determining the reliability function of the thermal power system in power plant "nikola tesla, block b1"
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2015)
Representation of probabilistic technique for evaluation of thermal power system reliability is the main subject of this paper. The system of thermal power plant under study consists of three subsystems and the reliability ...
A new form of equations for rigid body rotational dynamics
(Strojarski Facultet, 2014)
In the paper, a new form of differential equations for rigid body attitude dynamics is obtained. Three s-parameters (modified Rodrigues-Hamilton parameters) and three angular velocity parameters are used as unknown variables. ...
Visual enhancement of microcalcifications and masses in digital mammograms using modified multifractal analysis
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2015)
Microcalcifications and masses, as breast tissue anomalies (deviations from observed background regularity), may be viewed as statistically rare occurrences in a mammogram image. After recognizing their principal common ...
