Mathematical model of energy efficiency in internal spur gears
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
The impact of geometric parameters of teeth and lubricating oils to the efficiency of involute internal spur gears, when the transverse contact ratio is 2 lt epsilon(alpha) lt = 3, has been analyzed in this paper. The ...
Čovek koji je stvorio nacrtnu geometriju / The man who invented descriptive geometry
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2019)
Gaspar Monž je poznat kao otac moderne nacrtne i diferencijalne geometrije . Godine 1764. angažovan je da izradi detaljan nacrt utvrđenja u svom rodnom gradu i njegov rad je primetio jedan oficir iz vojne škole École Royale ...

Classification of Healthy and Cancer States of Colon Epithelial Tissues Using Opto-magnetic Imaging Spectroscopy
(Springer Heidelberg, Heidelberg, 2019)
Colorectal carcinoma (CRC) as a major health problem in industrialized countries is highly preventable and can be successfully treated in the early stages. However, incidence and mortality of CRC has increased over the ...
Effective wave slope coefficient of river-sea ships
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The effective wave slope is a fundamental concept in simplified 1-DOF roll models, and predicted roll motion strongly depends on the assumed effective wave slope coefficient. This is relevant to regulatory frameworks based ...
Theoretical study of AlN mechanical behaviour under high pressure regime
(Elsevier, Amsterdam, 2019)
Aluminum nitride (AlN) is a very important industrial and technological material due to its properties, e.g. high melting point, thermal conductivity, electrical resistivity, mechanical strength, and corrosion resistance. ...
Efficiency and power upgrade at the aged lignite-fired power plant by flue gas waste heat utilization: High pressure versus low pressure economizer installation
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
A substantial potential exists for the recovery of flue gas waste heat at aged coal-fired power plants. High and low pressure economizers (HPE, LPE) can be applied for this purpose. Two cases of the feedwater supply to the ...
