Underground loading-haulage equipment selection with application of topsis method with different weighting methods of criteria
The choice of adequate mining machines is one of the most complex problems in the underground exploitation of mineral raw materials. The weight of such a decision is reflected in the high prices of these machines and the occurrence of even greater costs during their use if their choice was wrongly conceived. There are numerous examples from practice in which such decisions were made solely on the basis of comparing the prices of machines, without considering any of the ...utovarno-transportna mehanizacija, izbor, TOPSIS, entropija, standardna devijacija, težina kriterijumaVladimir Krivošić, Luka Crnogorac, Rade Tokalić.

Machine learning based landslide assessment of the Belgrade metropolitan area: Pixel resolution effects and a cross-scaling concept
Improvements of Machine Learning-based landslide prediction models can be made by optimizing scale, customizing training samples to provide sets with the best examples, feature selection, etc. Herein, a novel approach, named Cross-Scaling, is proposed that includes the mixing of training and testing set resolutions. Hypothetically, training on a coarser resolution dataset and testing the model on a finer resolution should help the algorithm to better generalize ambiguous examples of landslide classes and yield fewer over/underestimations in the model. This ...Uroš Đurić, Miloš Marjanović, Zoran Radić, Biljana Abolmasov.

Reciklaža i ponovna upotreba flotacijske jalovine rudnika „Rudnik“ u cilju osvajanja tehnoloških postupaka prerade sekundarnih sirovina u Srbiji – projekat iz programa Prizma (2024-2026) - REASONING
Dragan S. Radulović, Jovica Stojanović, Grozdanaka Bogdanović, Vladimir Simić, Milena Kostović, Vladimir Jovanović, Dejan Todorović, Branislav Ivošević (2023)Velike količine flotacijske jalovine stvaraju se u Srbiji (preko 20 Mt), kao i u svetu (20.000-25.000 Mt). Zbog zaostalih teških metala (Pb, Cu, Fe i Zn...) ona predstavlja potencijalno opasni otpad koji bi trebalo zbog vrednosti plemenitih i obojenih metala u njoj reciklirati. Na Rudniku „Rudnik“ svake godine se generiše oko 250.000 t, flotacijske jalovine, od 1953. god. oko 11 Mt. Naučno istraživačkim radom i obavljenim ispitivanjima u okviru Projekta-REASONING (2024.-2026.) dobiće se rezultati i osvojiće se nova inovativna rešenja ...Dragan S.

Two approaches to compilation of bilingual multi-word terminology lists from lexical resources
In this paper, we present two approaches and the implemented system for bilingual terminology extraction that rely on an aligned bilingual domain corpus, a terminology extractor for a target language, and a tool for chunk alignment. The two approaches differ in the way terminology for the source language is obtained: the first relies on an existing domain terminology lexicon, while the second one uses a term extraction tool. For both approaches, four experiments were performed with two parameters being ...Branislava Šandrih, Cvetana Krstev, Ranka Stanković.

Određivanje broja kamiona za transport jalovine na površinskom kopu „Šuplja Stijena“
Siniša Bujišić (2024)U radu će se govoriti o praktičnoj primeni programskog paketa Talpac za određivanje broja kamiona za transport jalovine na površinskom kopu „Šuplja Stijena“, kao i o ulozi i značaju ovog programa u savremenom rudarstvu. Na osnovu ulaznih podataka i informacija vezanih za Šuplju Stijenu, uz pomoć programskog paketa Talpac izvršeno je projektovanje transportnih trasa. Transportne trase projektovane su tako da obezbede siguran rad ljudstva i opreme, a optimizovane su po pitanju transportnih dužina i organizacije proizvodnje. Kako bi se ......
