(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
Analitički izraz za verovatnoće stanja u zavisnosti od vremena, jednokanalnog sistema masovnog opsluživanja sa neograničenim redom M/M/1, je izveden. Izraz je izveden nalaženjem granične vrednosti izraza za verovatnoće ...
Practical aspects of finite element method applications in dentistry
(Udruženje stomatologa Balkana, 2017)
The use of numerical methods, such as finite element method (FEM), has been widely adopted in solving structural problems with complex geometry under external loads when analytical solutions are unachievable. Basic idea ...
Uticaj radijusa tranzicije donji pojas-rebro na lokalne napone / The impact of the transition radius lower flange-web on local stress of monorail crane girder
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
Širokopojasne profile sa paralelnom konturom pojaseva, koji se danas dominantno koriste za izradu jednošinskih nosača dizalica, karakteriše relativno veliki radijus tranzicije konture pojasa u konturu rebra. Upravo zbog ...
A structural integrity model for hydrogen embrittlement of low carbon steel and the combined effect of help and hede mechanisms on macromechanical properties
(International Conference on Fracture, 2017)
A large number of contemporary studies about hydrogen embrittlement confirmed the multiple effects of hydrogen and activity of the different hydrogen embrittlement mechanisms in low carbon steels. However, critical evaluation ...
Fracture behaviour of S316L stainless steel thin plates
(International Conference on Fracture, 2017)
Experimental investigation was conducted on thin CT specimens made of S316L stainless steel, well known for good corrosion and reasonable fracture properties. Standard fracture mechanics testing is performed, and compared ...
Determination of hydraulic losses in the flow passage between the guide vanes and runner of the Kaplan turbine
(Taylor & Francis Ltd, Abingdon, 2017)
Hydraulic losses in the region between the guide vanes and runner of a Kaplan turbine are commonly either neglected or considered a part of the total guide vanes losses. This paper focuses on the determination of these ...
Thermal analysis of physical and chemical changes occuring during regeneration of activated carbon
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
High-temperature thermal process is a commercial way of regeneration of spent granular activated carbon. The paper presents results of thermal analysis conducted in order to examine high-temperature regeneration of spent ...
Energy regeneration in automated high bay warehouse with stacker cranes
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
Fully automated electrically powered stacker cranes are the most common transportation devices used in automated high bay warehouses. When high throughputs are attained, the amount of the electric energy used is high. ...
Numerical research of the compressible flow in a vortex tube using openfoam software
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
The work presented in this paper is dealing with numerical simulation of energy separation mechanism and flow phenomena within a Ranque-Hilsch vortex tube. Simulation of turbulent, compressible, highly swirling flow inside ...
