Design of capacitive voltage divider for measuring ultrafast voltages
(Elsevier Sci Ltd, Oxford, 2018)
The aim of this paper is to consider and analyze design of capacitive voltage divider for measuring ultrafast voltage occurrence. Measuring pulse voltages by means of a capacitive divider in nanosecond range is affected ...
Exploring innovative solutions for aged concrete utilization: treatment of liquid radioactive waste
(Springer, New York, 2018)
In this study, the applicability of waste concrete as a sorbent material for the liquid radioactive waste management was considered. The sample was properly characterized in terms of mineralogical and surface composition, ...
Boundary-layer transition detection by thermography and numerical method around bionic train model in wind tunnel test
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
Methods of diagnosing aerodynamic characteristics are constantly developing in order to conduct the precise and energy efficient wind tunnel testing of transport vehicles in the prototype design early stages. This is of a ...
Calculation of the Archard's wear coefficient of the polymer-based composite sliding bearings
(Univerzitet u Novom Sadu - Fakultet tehničkih nauka, Novi Sad, 2018)
Prediction and calculation of wear of the mechanical components in contact is one of the most important tasks in modern engineering. Due to time consumptive experiments and quite expensive test rig, it became even more ...
Integrity assessment of turbine flat cover pipe
(Institut za ispitivanje materijala, Beograd, 2018)
The turbine flat cover pipe (dimension phi 219.1x12.7 mm, and material STPG-38) is tested and cracks are found. Determination of the required wall thickness for a pipe exposed to internal pressure is done according to EN ...
Pregled literature iz oblasti skladišnih sistema baziranih na šatl tehnologiji / A survey of literature on shuttle based storage and retrieval systems
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2018)
Prethodna decenija donela je pravi procvat u oblasti automatskih skladišnih sistema (SBS/RS) baziranih na šatl tehnologiji u mnogim industrijama. Njihova superiornost u odnosu na 'mini-load' automatske skladišne sisteme ...
Failure investigation and reparation of a crack on the boom of the bucket wheel excavator ERS 1250 Gacko
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Bucket wheel excavator ERs 1250 has been in operation for over 30 years in the Grae'anica-Gacko mining basin. It is operating in very hard working conditions due to exploiting very solid material, which has adverse effects ...
Effect of plasma hardfacing and carbides presence on the occurrence of cracks and microcracks
(Institut za ispitivanje materijala, Beograd, 2018)
Presented is the effect of plasma hardfacing (or just hardfacing) and carbides presence on the occurrence of cracks and microcracks in the welded layer. The reasons behind this phenomenon are analysed and explained. In ...
Modelling of creep behaviour of a rotating disc in the presence of load and variable thickness by using seth transition theory
(Institut za ispitivanje materijala, Beograd, 2018)
The purpose of this paper is to present study of creep behaviour of a rotating disc in the presence of load and thickness by using Seth's transition theory. It has been observed that a flat rotating disc made of compressible ...
Analysis of Comfort Parameters in Special Purpose Vehicles from Technological Development Point of View
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
The analysis of comfort parameters in the crew cabin space of two variants of the special purpose off-road vehicle is presented, taking technological development aspects into account. Tests of noise, vibration and heating ...
