Repair of cracks detected in cast components of vertical kaplan turbine rotor hub
(Institut za ispitivanje materijala, Beograd, 2019)
During the revitalization of the hydroelectric generating station A4 at the hydro power plant 'Djerdap 1', all of its parts are subjected to non-destructive testing. Cracks are detected in cast part of generator rotor hub, ...
Diesel production by fast pyrolysis of miscanthus giganteus, well-to-pump analysis using the greet model
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
In this paper "well-to-pump" environmental analysis of pyrolytic diesel from Miscanthus gigantheus is performed. The average annual yield of Miscanthus from III-V year of cultivation on 1 ha of chernozem soil in Serbia ...
Gap analysis and risk occurrence on the example of pressure transmitter's production processes
(Institut za istraživanja i projektovanja u privredi, Beograd, 2019)
Gap analysis represents a tool for raising the level of performances of products, processes and enterprise organization which is rarely used in risk management. This paper proposes the joint application of Gap and Pareto ...
Micromechanical modelling of ductile fracture - local approach
(Savez inženjera metalurgije Srbije, Beograd, 2019)
Micromechanical modelling of ductile fracture by using the local approach has been presented as the review of previously obtained results for welded joints made of low alloyed high strength steel. Experimental work was ...
Machine Learning Classification of Cervical Tissue Liquid Based Cytology Smear Images by Optomagnetic Imaging Spectroscopy
(Univ Osijek, Tech Fac, Slavonski Brod, 2019)
Semi-automated system for classification of cervical smear images based on Optomagnetic Imaging Spectroscopy (OMIS) and machine learning is proposed. Optomagnetic Imaging Spectroscopy has been applied to screen 700 cervical ...
Tačka najvećeg napona na konturi kvadratnog otvora u ploči / Hot spot along corner curvature of rectangular plate opening
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2019)
Koncentracija napona u uglu kvadratnog otvora u ploči je poznata činjenica. Najčešće se uzima da je najveća koncentracija napona u samom temenu ugla (na ugaonoj koordinati od 45 stepeni u slučaju kvadratnog otvora). ...
