Numerical analysis of anchored bored piles in fractured rock masses
(ICE Publishing, 2015)
Grdelicka gorge, through which upcoming Motorway E-75 will pass by, is made of very old rock masses, influenced by strong tectonic forces and severe physical, chemical and erosion processes. The oldest and most frequents ...
Irreversible changes of vacuum circuit breakers' dielectric strength as a result of current breaking operation
(Institute of Electrical and Electronics Engineers Inc., 2015)
In the vacuum switching element, current breaking operations cause the changes of the electrodes' surface by means of the following mechanism: 1 - cathode erosion (during the movement of electric arc's cathode spot); 2 - ...
Characteristics' optimization of gas-filled surg arresiers by using gas mixtures
(Institute of Electrical and Electronics Engineers Inc., 2015)
The increasing trend of electronic components' miniaturization makes them unresisting to overvoltage occurrences. Therefore, it is necessary to pay special attention to overvoltage protection at the low-voltage level. ...
The parameters of the free electrons gas spectrum of noble gases mixture at small pressures and inter-electrode distances
(Institute of Electrical and Electronics Engineers Inc., 2015)
Strictly speaking, electrically uncharged and electrically charged gas mixtures can approach the Maxwell's specter in the context of low-ionized mono-atomic mixtures within a weak electric field. The parameters of the ...
The correlation and regression between the pre-breakdown current and breakdown voltage of the vacuum switchgear in dependence of switching operation
(Institute of Electrical and Electronics Engineers Inc., 2015)
Determining the correlation and regression is a statistical method applied when several random variables are simultaneously being measured on the same statistical sample and if their interdependency is being investigated. ...
The construction of capacitive voltage divide for measuring ultrafast pulse voltage
(Institute of Electrical and Electronics Engineers Inc., 2015)
The problem of pulse voltage measurements in the nanoseconds range has become of great importance with ongoing problems related to the construction of pulse fusion generators as well as with simulations of electromagnetic ...
The influence of illumination parameters on the performances of color sorting machines
(Scientific Proceedings XII International Congress "Machines, Technologies, Materials" 2015, 2015)
The color recorded in the image is not an inherent value of observed object, because it is also influenced by the illumination properties, as well as geometry and surfaces of neighboring objects. Numerous studies have ...
Microstructural characterization of WC and CrC based coatings applied by different processes
(Associations of Metallurgical Engineers of Serbia - AMES, 2015)
Numerous mechanical structures and assemblies have frequent outages
because of wear of machine parts due to the effects of abrasion and erosion.
There are several methods to protect parts from wear and one of them is ...
Role of hydroelectric power plant in development of Uzice and Bajina Basta settlements
(Faculty of Mechanical Engineering, University of Belgrade, 2015)
This paper demonstrates the link between the construction of hydroelectric power plant and the development of settlements in the surrounding area. The influence of electrification and industrialization in urban restructuring ...
A simple digital imaging method for the analysis of the color of food surfaces
(Faculty of Mechanical Engineering, University of Belgrade, 2015)
Compared to manual inspection, which is inconsistent and subjective, sorters are able to assure product quality and food safety by more effectively identifying and removing defects and foreign material, while at the same ...
