Towards the semantic annotation of SR-ELEXIS corpus: Insights into Multiword Expressions and Named Entities
Овај рад представља активности на развоју корпуса ELEXIS-sr, српском додатку вишејезичном анотираном корпусу ELEXIS-а, који се састоји од семантичких анотација и репозиторија значења речи. ELEXIS је паралелни вишејезични анотирани корпус на десет европских језика, који може да се користи као вишејезички репер за евалуацију европских језика са мање и средње развијеним ресурсима. Фокус овог рада је на вишечланим изразима и именованим ентитетима, њиховом препознавању у скупу реченица ELEXIS-sr и поређењу са анотацијама на другим језицима. Разматрају се први кораци ...Cvetana Krstev, Ranka Stanković, Aleksandra Marković, Teodora Mihajlov.

Navigacija budućnosti: poslovni rizici i prilike u rudarskoj industriji
Sektor rudarstva i metalurgije se globalno suočava sa brzo evoluirajućim okruženjem u 2024. godini, koje karakteriše jedinstvena međusobna zavisnost rizika i prilika. Sektor je u središtu globalne energetske tranzicije, uz rastuću potražnju za kritičnim mineralnim sirovinama poput litijuma, nikla i bakra, koji su od suštinskog značaja za tehnologije obnovljive energije i električna vozila. Međutim, ova sve veća odgovornost donosi brojne izazove, uključujući pojačanu pažnju na ekološke, društvene i upravljačke (ESG) faktore, fizičke i tranzicione rizike uzrokovane klimatskim promenama, i ...Petar Marković, Dejan Stevanović, Mirjana Banković, Vuk Lazić.

Analiza rada električnih centrifugalnih pumpi
Milica Stanojević (2024)Ovaj rad analizira rad električne centrifugalne pumpe (ESP) u naftnoj industriji, sa fokusom na problem taloženja kamenca (karbonatnih naslaga) unutar sistema. Električne centrifugalne pumpe (ESP) predstavljaju srce mnogih naftnih bušotina. Njihova visoka pouzdanost i sposobnost rada u zahtevnim uslovima čine ih neophodnim za stabilnu i kontinuiranu proizvodnju.Senzori igraju ključnu ulogu u praćenju rada ESP sistema i detekciji ranih znakova taloženja kamenca. Problem taloženja kamenca je izuzetno značajan, jer može dovesti do smanjenja efikasnosti pumpe, povećanja troškova održavanja, i dugoročnih zastoja ...... prezime i nastavno zvanje, član Prof. dr Dušan Danilović Rudarsko-geološki fakultet, Beograd 3.
