Evalution of concretes with standard and recycled raw materials for high temperature application
(Revista Romana de Materiale/ Romanian Journal of Materials, 2012)
Concrete undergoing thermal treatment before and during life-service can be applied as building material for thermal insulation in high-temperature plants. When such concretes are designed with secondary raw materials they ...
MSV sistem za obradu signala sa neutron-gama diskriminacijom u mešovitom polju / MSV signal processing system for neutron-gamma discrimination in a mixed field
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2012)
Na osnovu principa koji su proizišli iz Kempbelove teoreme, u ovom radu je urađena analiza nekih mogućnosti Kempbelovog MSV sistema za obradu signala. MSV mod je posebno pogodan za merenja koja se sprovode u mešovitom polju ...
Application of neural networks in determination of compressive strength of concrete
(Revista Romana de Materiale/ Romanian Journal of Materials, 2012)
This paper presents the optimization of concrete mixtures composition related to a physical property and the process of production of trial mix design by using the multi-layered feed-forward neural networks. This optimization ...
Osnove ispitivanja integriteta šipova s primerima iz prakse / Basis of pile integrity testing with few case histories
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2012)
U poslednjih nekoliko godina, ispitivanje integriteta ugrađenih šipova postalo je veoma popularno na gradilištima u našoj zemlji. Pri tom, posebno mesto zauzima zvučna metoda, 'Sonic Integrity Test' kao pouzdana, jeftina ...
Procena ponašanja zavarenog spoja HSLA čelika opterećenog na zamor primenom parametara mehanike loma / Assessment of the behaviour of fatigue loaded HSLA steel welded joint by applying fracture mechanics parameters
(Institut za ispitivanje materijala, Beograd, 2012)
U zavarenim spojevima, sa gledišta mehanike loma, se pretpostavlja prisustvo prslina, gde se onda vek s obzirom na zamor takvih konstrukcija sa prslinama procenjuje vremenom rasta prsline pod promenljivim opterećenjem. ...
Recovery of the damages of a welded steel structure of a coal-reloading bridge: Methodological approach
(Univerzitet u Novom Sadu - Fakultet tehničkih nauka, Novi Sad, 2012)
In present paper, the methodological approach to the analysis of the causes of failures and to recovery of the damages has been presented using, as an example, the fracture and damage of a welded steel structure of a ...
Removal of toxic metals from industrial sludge by fixing in brick structure
(Elsevier Sci Ltd, Oxford, 2012)
The aim of this study was to test utilization possibilities of industrial sludge in masonry industry, as well as risk of toxic elements leaching potential. Sludge is generated in a hot-dip galvanizing process after waste ...
Metodologija reparaturnog zavarivanja vratila turbina na hidroelektrani Đerdap 2 bez demontaže agregata

Na deset hidro-generatorskih jedinica 'Đerdap 2' ugrađene su horizontalne Kaplan turbine, nominalne snage 28 MW, izrađene u Rusiji. Posle 163411h rada (približno 22 godine) došlo je do loma vratila turbine agregata A6 u ...
Monte Carlo Analysis of the Influence of Different Packaging on MOSFET Energy Response to X-rays and Gamma Radiation
(Polish Acad Sciences Inst Physics, Warsaw, 2012)
Radiation sensing MOSFETs have found numerous applications as detectors or device components in radiation fields used in nuclear industry, medical applications and space research. Monte Carlo simulations of MOSFET energy ...
A new methodology for prediction of high-cycle contact fatigue for spur gears
(Univerzitet u Novom Sadu - Fakultet tehničkih nauka, Novi Sad, 2012)
High-cycle contact fatigue is a localized phenomenon that occurs in highly stressed grains of the material on or under the contact region. The contact zones of tooth flanks for meshed gears are subjected to contact fatigue ...
