Multiple-Criteria Decision-Making in Mine Development Planning
Sanja Bajić (2023)The Borska Reka ore deposit is an experimental location where developed methodologies have been applied. It is the largest ore body within the Bor mining complex, which has been the subject of numerous studies and analyses for more than three decades. The paper focuses on the application of FAHP and the VIKOR method to address ranking of alternatives and select the optimal mining method by means of fuzzy multicriteria optimization.Sanja Bajić.

Značaj izvodjenja Proktorovog opita na komunalnom otpadu
Komunalni otpad predstavlja jedan od ključnih problema današnjice. U Srbiji je najčešći vid odlaganja otpada na komunalne deponije i zbog toga je bitno ispravno i sigurno ga skladištiti. Zbijanje komunalnog otpada predstavlja jednu od osnovnih komponenti procesa odlaganja. Kako bi se što bolje predvidelo ponašanje komunalnog otpada neophodno je pre zbijanja na terenu laboratorijski odrediti maksimalnu suvu zapreminsku težinu i optimalnu vlažnost. U dosadašnjoj praksi u svetu za to se koristi standardizovan Proktorov opit. U radu će biti prikazani ...... projekat TR 36014 koji se finansira od strane Ministarstva prosvete, nauke i tehnološkog razvoja Republike Srbije. LITERATURA: Cox, J.

Model inteligentnog sistema adaptivnog upravljanja procesom prerade rude
Ivana M. Jovanović (2016-01-13)U oblasti procesa prerade rude, flotacijska koncentracija predstavlja jednu od najznačajnijih i najčešće primenjivanih metoda separacije korisnih od nekorisnih minerala. Samim tim, veoma je važno osigurati uspešan rad flotacijskog postrojenja kroz dostizanje zadovoljavajućih tehno-ekonomskih pokazatelja. Cilj upravljanja procesom flotacijske koncentracije je upravo optimizacija kvaliteta i iskorišćenja korisne komponente u koncentratu uz maksimizaciju profita. Shodno tome, istraživanja na polju modelovanja i upravljanja ovim procesom zauzimaju značajno mesto u praksi kontolnog inženjenringa.Teorijska istraživanja u okviru doktorske disertacije obuhvatila su analizu položaja ...flotacijska koncentracija, modelovanje, upravljanje, inteligentni sistem, soft kompjuting, fazi logika, veštačke neuronske mreže... network.

Dehydroicetexanes in sediments and crude oils: Possible markers for Cupressoideae
Hans Peter Nytoft, Geir Kildahl-Andersen, Sofie Lindström, Frode Rise, Achim Bechtel, Danica Mitrović, Nataša Đoković, Dragana Životić, Ksenija A. Stojanović (2019)Two previously unidentified dehydroabietane isomers were isolated from Miocene Serbian lignite and Rhaetian (Late Triassic) coaly mudstones from South Sweden and characterized using NMRspectroscopy as cis- and trans-dehydroicetexane. Both have a 9(10?20)-abeo-abietane or icetexane skeleton, consisting of a 6-7-6 tricyclic framework with seven carbons in ring B instead of the usual six in common diterpanes of the abietane-type. Dehydroicetexanes can be detected using GC-MS-MS in m/z 270?146 chromatograms without interference from dehydroabietane or other isomers. Dehydroicetexanes are often abundant ...Hans Peter Nytoft, Geir Kildahl-Andersen, Sofie Lindström, Frode Rise, Achim Bechtel, Danica Mitrović, Nataša Đoković, Dragana Životić, Ksenija A. Stojanović.
