Одређивање оптималних параметара цевовода за двофазни проток
Николина Ћурчић (2024)Eфикасно управљање протоком флуида је кључно за оптимизацију перформанси система и обезбеђивање оперативне сигурности. Двофазни ток, који подразумева истовремено присуство течне и гасне фазе унутар цевовода и измењивача топлоте, представља један од најсложенијих аспеката динамике флуида. Овај феномен намеће јединствене изазове који захтевају дубоко разумевање и прецизно планирање. Ефикасно управљање двофазним током није само кључно за одржавање ефикасности система, већ је и неопходно за спречавање потенцијалних проблема као што су повећана ерозија, неочекиване флуктуације притиска и ризици по безбедност.

BERT Downstream Task Analysis: Named Entity Recognition in Serbian
This paper compares different architectures and techniques for preparing named entity recognition (NER) models for the Serbian language via integrating BERT with spaCy. Models were trained to recognize seven different named entity types (persons, locations, organisations, professions, events, demonyms, and artworks), and are trained on the dataset containing Serbian novels published between 1840 and 1920, publicly available newspaper articles and sentences generated from the Wikidata knowledge base and Leximirka lexical database.

Tectonic evolution of the Vršac Mts. (NE Serbia): Inferences from field kinematic and microstructural investigations
The Vršac Mts. in NE Serbia represent the key area to investigate structural relations between the Northern Serbo-Macedonian Subunit and Supragetic Unit of the Dacia Mega-Unit. The geodynamic events during the Variscan orogeny in the Late Paleozoic colligated the two units and led to their metamorphic differentiation. The Late Cretaceous extension exhumed the medium-grade Serbo-Macedonian metamorphic rocks and structurally juxtaposed them against the low-grade metamorphosed basement of the Supragetic Unit along an E-dipping shear zone, which outcrops in the ...severna srpsko-makedonska subjedinica, supragetikum, kinematska analiza, multifazna ekstenzionalna deformacijaUroš Stojadinović, Nemanja Krstekanić, Bojan Kostić, Marija Ružić, Aleksa Luković .

Prioritization of strategic measures for strengthening the security of supply of the Serbian natural gas sector
To strengthen the security of supply of the Serbian gas sector, it is necessary to analyze the impact of planned strategic measures. The analysis involves the identification of the most influential threats to the security of natural gas supply and prioritization of the strategic measures for overcoming the consequences of threats. The proposed methodology is based on Fuzzy Analytic Hierarchy Process. The obtained weights for the identified threats and strategic measures are formed according to experts' judgments.

Геолошке карактеристике лежишта ватросталних глина „Лазине“
Давид Божић (2024)Овај дипломски рад бави се геолошким истраживањем и анализом лежишта ватросталних глина Лазине, које се налази у Србији. Ватросталне глине имају изузетно важну примену у индустрији, нарочито у производњи ватросталних материјала, као што су опеке и облоге које издржавају високе температуре. Циљ рада био је да се испита квалитативни састав и карактеристике глина и лежишта ,,Лазин'' процени економски значај лежишта, као и да се дефинишу потенцијали за експлоатацију и будућу производњу. Анализирана су геолошка својства терена, укључујући минералошки састав, ...... caommrasarbc ncna, m upepa/ie, ako cc HaBc;c Mc ayTopa Ha HaunH OJipebeH ojt crpaiic ayropa H naBaoia BHIICHIIC, SaK M y KoOMCpLMjanHe cBpxe.

Geonasleđe Golije i Peštera
Ljiljana V. Grujičić-Tešić (2017-09-01)Sprovedena istraživanja u ovoj studiji obuhvatila su izdvajanje, opis, evaluaciju i valorizaciju objekata geonasleđa u cilju razvoja istraživane oblasti sa stanovišta geonauka, geoturizma i geoekologije. Na izučavanom području objekti geonasleđa su evidentirani, interpretirani, vrednovani i kategorisani, dat je predlog promocije geoobjekata, i na kraju predložena dopuna inventara objekata geonasleđa Srbije.U protekle četiri godine, na kompleksu geotopa Golije i Peštera istražena su geološka svojstva stena (tip stene, starost, fosilni sadržaj, morfološke i hidrogeološke karakteristike itd.), na osnovu čega je bilo ...Ljiljana V.
