Prognoza operativne efikasnosti aktivnog podzemnog rudnika zasnovana na teoriji sivih sistema
Svetlana M. Štrbac-Savić (2016-06-10)Efikasnost predstavlja preduslov za opstanak svake rudarske kompanije, posebno u uslovima izuzetno konkurentnog trţišnog okruţenja kao što je to rudarska industrija. Efikasnost oznaĉava sposobnost kompanije da ispuni svoje kratkoroĉne ili dugoroĉne ciljeve. Operativna efikasnost se definiše kao odnos izmeĊu ulaznih parametara potrebnih za odvijanje proizvodnje i pokazatelja dobijenih proizvodnjom. U kontekstu rudarskog poslovanja, operativna efikasnost se odnosi na vreme potrebno da se mineralno dobro transformiše u novĉana sredstva.

Препреке декарбонизацији система даљинског грејања у Србији - ставови представника топлана
Производња топлоте у системима даљинског грејања у Републици Србији тренутно се заснива искључиво на процесима сагоревања, с доминантним уделом природног гаса из увоза. Иако су технологије за коришћење обновљивих и алтернативних извора енергије добро познате, њихова примена у системима даљинског грејања у Републици Србији још увек је занемарљива (око 2%). Како би се убрзао и олакшао процес транзиције ка обновљивим изворима енергије и разумело тренутно стање и перспектива, спроведена је анкета међу представницима топлана Србији. Циљ је био ...Марија Живковић, Дејан Ивезић, Бобан Павловић, Дејан Стојановић.

Modeliranje disperzije dimnih gasova iz termoelektrane Kostolac B
Bojan Živanović (2024)Bez hrane se može preživeti nedelju dana, bez vode svega nekoliko dana, međutim, bez vazduha se može preživeti najmanje, nekoliko minuta. Pitanje je kakav uticaj na zdravlje čoveka i okoline ima vazduh koji je lošeg kvaliteta, a kojem je skoro celokupno stanovništvo planete izloženo? Ovaj rad se bavi problematikom modeliranja disperzije dimnih gasova iz novog bloka B3 TE ,,Kostolac’’ B. Ključni momenti koji će biti predstavljeni jesu zagađenje, zdravstveni efekti, modeliranje disperzije i analiza dobijenih rezultata korišćenjem programa AERMOD. Analiziran ......

Geofizičko reflektivno sondiranje kao test integriteta betonskog šipa
Jovo Jakišić (2024)Temelj predstavlja izuzetno bitan element svakog građevinskog objekta. Zbog toga je neophodno poštovati odgovarajuće standarde, u projektovanju i izvođenju temeljne konstrukcije.Šipovi predstavljaju jedan od načina dubokog fundiranja tj. temeljenja. Za svaki izvedeni šip pojedinačno neophodno je izvesti kontrolu kvaliteta. Postoji više postupaka kojima je mogućeizvršiti kontrolu kvaliteta, a jedan od njih je test integriteta šipa malom silom, koji je prikazan u ovom radu.Ovaj postupak se izvodi seizmometrijskom metodom, postupkom refleksije, koji je definisan međunarodnim standardom ASTM D5882.Podaci koji su prikazani ......
