Determining the Availability of Continuous Systems at Open Pits Applying Fuzzy Logic
This work presents a model for determining the availability of continuous systems at open pits by applying fuzzy logic and fuzzy inference systems. The applied model was formed by the synthesis of independent partial indicators of availability. The model is based on an expert system for assessing the availability of continuous mining systems. The availability of the system, as a complex state parameter, is decomposed into the partial indicators, reliability, and convenience of maintenance, and the fuzzy compositions, used ...системи, континуални систем експоатације, површински коп, рударство, расположивост, фази логика, max–min композиција, min–max композицијаMiljan Gomilanović, Miloš Tanasijević, Saša Stepanović.

Modeliranje tehnoloških procesa u rudarstvu u uslovima nedovoljnosti podataka primenom teorije grubih skupova
Zoran M. Štirbanović (2015-07-01)Rudarstvo, a u okviru njega i priprema mineralnih sirovina, se odlikuje složenošću tehnoloških procesa što je posledica velikog broja uticajnih parametara. Samim tim je potrebno biti veoma obazriv prilikom donošenja odluka u oblasti rudarstva. U cilju što efikasnijeg funkcionisanja procesa, moguće je primeniti različite metode koje služe za pojednostavljenje procesa odlučivanja. Jedna od takvih metoda jeste i teorija grubih skupova. Ona predstavlja relativno novu matematičku teoriju koja je pogodna za razumevanje nepreciznih i nepotpunih podataka kao i za otkrivanje ...rudarstvo, priprema mineralnih sirovina, teorija grubih skupova, višekriterijumsko odlučivanje, flotacijsko jalovište, flotacijski kolektor, flotaciona mašina... i zavisnost: a) B' ⇒ B − B', gde je B’ redukcija od B.

Numerical Models of Debris Flows with Entrainment Analysis-Case Studies from the Republic of Serbia
The results of material entrainment analysis in RAMMS debris flow software, as well as numerical models of final flow heights for two case studies from the Republic of Serbia are presented. Both of debris flow cases started with initial sliding of huge volume block, prolonging to behave as flowing process. Results of the analysis showed that entrainment material affects final results of transportation model, runout distance, deposition area and volume of debris flow. In both cases entrainment volume is very ...Jelka Krušić , Biljana Abolmasov, Miloš Marjanović.

Assessment of spa mineral water quality from Vrnjačka Banja, Serbia: geochemical, bacteriological, and health risk aspects
Nebojša Đ. Pantelić, Simona Jaćimović, Jana Štrbački, Danijela B. Milovanović, Biljana P. Dojčinović, Aleksandar Ž. Kostić (2019)The goal of this study is to evaluate the quality of seven natural mineral water sources in the Vrnjačka Banja area used in the treatment of various diseases. The 24 macro- and microelements were determined by inductively coupled plasma optical emission spectrometry (ICP-OES). The results show that element content was within allowed limits of concentration, except for B, As, and Se. The evaluated content of these elements can be associated with geological and anthropogenic factors. The sample S6 contains ...Nebojša Đ. Pantelić, Simona Jaćimović, Jana Štrbački, Danijela B.

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.

Projection of SO2 emissions in coal power plants in Serbia
Aleksandar Madžarević, Predrag Jovančić, Stevan Đenadić, Filip Miletić, Miodrag Ristović, Miroslav Crnogorac (2023)The production of electricity in the countries of South-Eastern Europe (SEE) was mainly related to the use of coal, predominantly lignite. The total installed capacity of thermal power plants using coal in these seven countries is 17.813 MW, distributed in 31 thermoblocks. The mentioned plants are the dominant pollutant emitters in all observed countries. Data on the largest emitters in the countries of the European Union and a comparison with SEE countries were collected.
