Water Hydrogen Bonds Study by Opto-Magnetic Fingerprint Technique
(Polish Academy of Sciences, 2010)
Hydrogen bond has dual property, classical (electrostatic interaction based on Coulomb's law) and quantum (wave function based on Schrodinger equation). Since Planck's constant is one of the main criteria for decision which ...
Laser sheet scattering and the cameras' positions in particle image velocimetry
(Polish Academy of Sciences, 2007)
Simulations of laser sheet scattering by microparticles, based on the generalized Lorenz-Mie theory for the case of numerous random spatial distributions of scattering particles, were done, using the novel computational ...
Comparative analysis of hybrid composites based on A356 and ZA-27 alloys regarding their tribological behaviour
(Komunikácie – Communications, 2023)
The comparative analysis of the two hybrid composites, obtained by the compocasting process, based on A356 and ZA-27 alloys and reinforced with 10 wt. % SiC and 0, 1 and 3 wt. % graphite (Gr) is presented. Optimisation of ...
Rectified ethanol production cost analysis
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
This paper deals with the impact of the most important factors of the total production costs in bioethanol production. The most influential factors are: total investment costs, price of raw materials (price of biomass, ...
The characteristics of combustion process of diesel engine using vegetable oil methyl esters
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2015)
Biodiesel is one of the promising renewable, alternative, and environmentally friendly biofuels that can be used in Diesel engine with little or no modification in the engine. The present paper investigates the combustion ...
Numerical and experimental determination of stress concentration factor for a pipe branch model
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
The subject of this paper is testing of complex geometrical structures, i.e. stress analysis of a pipe branch model of A6 third pipeline at Hydropower Plant Perucica, Niksic. Analysis of pipe branch model stress distribution ...
Reduced Order Numerical Modeling for Calibration of Complex Constitutive Models in Powder Pressing Simulations
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
Numerical simulations of different ceramic production phases often involve complex constitutive models, with difficult calibration process, relying on a large number of experiments. Methodological developments, proposed ...
Numerical study on hygroscopic material drying in packed bed
(Brazilian Soc Chemical Eng, Sao Paulo, 2011)
The paper addresses numerical simulation for the case of convective drying of hygroscopic material in a packed bed, analyzing agreement between the simulated and the corresponding experimental results. In the simulation ...
Instability of equilibrium of nonholonomic systems with dissipation and circulatory forces
(SHANGHAI UNIV, SHANGHAI, 2011)
The paper discusses the equilibrium instability problem of the scleronomic nonholonomic systems acted upon by dissipative, conservative, and circulatory forces. The method is based on the existence of solutions to the ...
Laser Interaction with Material - Theory, Experiments and Discrepancies
(Polish Academy of Sciences, 2009)
The experimental treatment of chosen material with laser beams, starting from continuous wave up to fs pulses, produces the necessity to find the common and sophisticated theoretical approaches to interaction modeling. For ...
