Replica of the “Great Triangle Gold Nugget” Belonging to Belgrade University Collection, Gilded or Not?
... Belgrade in Serbia, has been holding over a hundred years the gypsum model of triangular shape that represents the replica of one of the world’s largest native gold nugget weighing 36.2 kg, known as “The Great Triangle”. Nugget model is golden metallic in colour with a shape similar to a rectangular ...
... Since the gold colour and shine remained the same, did not darken by the time it was assumed that the model is gilded. Material and method Chemical composition of the gypsum model surface was carried out in the Laboratory for SEM, Faculty of Mining and Geology, University of Belgrade ...
... the type and manner of material that was used for covering. Result and conclusion The data obtained by EDS analysis show that the gypsum model is covered with gold leaf, which was expected according to the macroscopic characteristic of the object. How many such gilded replicas of the ...Alena Zdravković, Maja Milošević, Ivana Jelić.

Ontološki model upravljanja rizikom u rudarstvu
Olivera Kitanović (2021)Rudarska proizvodnja obuhvata kompleksne tehnološke sisteme, što nameće potrebu za uspostavljanjem i unapređivanjem sistema upravljanja rizikom. Heterogenost i obim podataka neophodnih za upravljanje rizikom zahtevaju sistem koji ih na fleksibilan način integriše i omogućava njihovo optimalno korišćenje. Osnovni cilj ove disertacije je razvoj ontologije za domen rudarstva i na njoj zasnovanog modela za upravljanje rizikom. Njegova realizacija podrazumeva i implementaciju algoritama ekstrakcije informacija za popunjavanje ontologije, kao i odgovarajuće softversko rešenje. Razvoj modela obuhvata i značajno proširenje rudarskog korpusa, kao ...rudarstvo, rizik, upravljanje rizikom, procena rizika, ontologija, semantička mreža, ekstrakcija informacija, upravljanje znanjem, računarska lingvistika... što znači da klasa može imati više instanci jednog atributa. Kod relacionih modela, jedna instanca može imati samo jednu vrednost atributa. Svaka klasa, kao i svaka instanca jedne klase može se povezati sa drugim jezičkim resursima, domaćim ili stranim, a na slici je prikazano referenciranje rizika ...

Isti PrefixSpan algoritam koristi se i za ekstrakciju pravila za utvrđivanje različitih uzroka i njihovih potencijalnih uticaja na rizik, koristeći označeni niz uzroka i uticaja. Jezičkim pravilima pridružene su vrednosti koje se koriste ...
... Evaluacija je ukazala na obećavajuće rezultate automatizovane analize i identifikacije rizika (Dasgupta and Dey 2016). Primećeno je da pojava određenih jezičkih obrazaca vrsta reči igra važnu ulogu u određivanju faktora rizika i samih rizika.

Multi-Criteria Fuzzy-Stochastic Diffusion Model of Groundwater Control System Selection
When considering data and parameters in hydrogeology, there are often questions of uncertainty, vagueness, and imprecision in terms of the quantity of spatial distribution. To overcome such problems, certain data may be subjectively expressed in the form of expert judgment, whereby a heuristic approach and the use of fuzzy logic are required. In this way, decision-making criteria relating to an optimal groundwater control system do not always have a numerical value. Groundwater control scenarios (alternatives) are identified through hydrodynamic ...expert judgment, linguistic variables, fuzzy dynamic TOPSIS, hydrogeology, groundwater control system, open-cast mine, geometric Brownian motionDušan Polomčić, Zoran Gligorić, Dragoljub Bajić, Miloš Gligorić, Milanka Negovanović.
