Development of an Integrated Model for Open-Pit-Mine Discontinuous Haulage System Optimization
Miodrag Čelebić, Dragoljub Bajić, Sanja Bajić, Mirjana Banković, Duško Torbica, Aleksej Milošević, Dejan Stevanović (2024)The selection of the optimal equipment for discontinuous haulage systems is one of the most important decisions that need to be made when an open-pit mine is designed. There are a number of influencing factors, including natural (geological and environmental), technical, economic, and social. Some of them can be expressed numerically, in certain units of measure, while others are descriptive and can be stated by linguistic variables depending on the circumstances of the project. These factors are characterized by ...Miodrag Čelebić, Dragoljub Bajić, Sanja Bajić, Mirjana Banković, Duško Torbica, Aleksej Milošević, Dejan Stevanović.

Improving Document Retrieval in Large Domain Specific Textual Databases Using Lexical Resources
Large collections of textual documents represent an example of big data that requires the solution of three basic problems: the representation of documents, the representation of information needs and the matching of the two representations. This paper outlines the introduction of document indexing as a possible solution to document representation. Documents within a large textual database developed for geological projects in the Republic of Serbia for many years were indexed using methods developed within digital humanities: bag-of-words and named ...Ranka Stanković, Cvetana Krstev, Ivan Obradović, Olivera Kitanović.

Geotehnički uslovi izgradnje tunela „Debelo brdo“ na autoputu E-80 Niš - Pločnik
Tunel „Debelo brdo“ nazvan je po najizraženijem relјefnom obliku na ovoj drugoj deonici autoputa E-80 Niš – Pločnik. Osnovnu geološku građu na lokaciji tunela čini Mio-Plioceni kompleks heterogenog litološkog sastava. Izgradnja tunela je predviđena delom u otvorenom iskopu dužine 240 m, a delom sa podzemnim iskopom dužine 190 m. U zoni tunela, padina je okarakterisana kao uslovno stabilna, pa bi neadekvatna zasecanja mogla da izazovu klizanja terena.

Late and post-collisional tectonic evolution of the Adria-Europe suture in the Vardar Zone
The Vardar Zone is a product of the Triassic-Jurassic opening of the Neotethys, Jurassic obduction, Late Cretaceous/Paleogene consumption of the oceanic crust and continental collision. During the last process, the Eastern Vardar Zone was thrust over the Central and eventually both onto the Western Vardar Zone. The present paleomagnetic and structural study provided new results from the first two zones in the Belgrade area. The younger set of data, together with published ones from the third zone, provide firm ...Emő Márton, Marinko Toljić, Vesna Cvetkov.

Модел померања терена услед утицаја рударских радова на основу радарских сателитских снимака
Зоран Гојковић (2023)Површински коп, као систем који обезбеђује енергетску стабилност или снабдевање сировинама које су од изузетне важности за привредни напредак, својим функционисањем утиче на околна насељена места. Међу бројним аспектима овог утицаја, може се издвојити издвојити и анализирати утицај вертикалних и хоризонталних померања која се јављају на површи терена. Мониторинг вертикалних и хоризонталних померања површи терена околних насељених места треба да има што бољу временску резолуцију (временски период између праћења деформација) како би се вертикална и хоризонтална померања контролисала и ...Зоран Гојковић.

Copper minerals flotation in flotation plant of the "rudnik" mine
У флотационој фабрици рудника "Рудник" користи се јединствена технологија директне селективне флотације у циљу добијања селективних концентрата олова, бакра и цинка. Технолошки процес је веома осетљив на тзв. "селективност", јер је присутан губитак појединих метала кроз селективне концентрате. Циклус флотације бакарних минерала посебно је осетљив на селективност, па понекад у бакарном концентрату постоји већи садржај минерала олово и цинка, што се пенализује. У овом раду приказани су резултати лабораторијских истраживања могућности смањења садржаја галене и цинка у бакарном концентрату ...Predrag Lazić, Đurica Nikšić, Branislav Miković, Rudolf Tomanec.

On the compatibility of lexical resources for NooJ
Lexical resources for many languages are provided for the NooJ linguistic development environment. Meta-data descriptions of morphosyntactic and semantic properties of these languages and their resources are a mandatory part of each language module. In this paper we analyze how well the meta-data actually describe resources for a chosen subset of languages and to what extent are they compatible across languages to support multilingual processing. We show that there is place for improvement in both directions.Ranka Stanković, Miloš Utvić, Duško Vitas, Cvetana Krstev, Ivan Obradović.

Mechanosynthesis and structural characterization of nanocrystalline Ce1–Y O2– (x=0.1–0.35) solid solutions

For thefirst time, complementary information on both the long-range and short-range structural features of mechanosynthesized Ce1–xYxO2–δ, obtained by Rietveld analysis of XRD data and Raman spectroscopy, is provided. The lattice parameters of the as-prepared solid solutions decrease with increasing yttrium content.
