  • Razvoj integralnog modela za optimizaciju diskontinualnog sistema proizvodnje na površinskim kopovima nemetala

    Miodrag Čelebić (2024)
    Izbor optimalne mehanizacije u diskontinualnom sistemu transporta je jedna od najvažnijih odluka koju treba donijeti prilikom projektovanja površinskih kopova. Pri izboru optimalne mehanizacije, uticaj ima veliki broj faktora, kako prirodnih – geoloških i ekoloških, tako i tehničkih, ekonomskih i socijanih. Neki od njih se mogu izraziti numerički, u određenim mijernim jedinicama, a neki opisno, lingvističkim varijablama, shodno uslovima koji vladaju na rudnim ležištima, a koje karakterišu visok stepen neizvjesnosti i neodređenosti kako prilikom istraživanja, tako i tokom procesa eksploatacije ...

  • Surface functional groups and degree of carbonization of selected chars from different processes and feedstock

    Marija Ilić, Franz-Hubert Haegel, Aleksandar Lolić, Zoran Nedić, Tomislav Tosti, Ivana Sredović Ignjatović, Andreas Linden, Nicolai D. Jablonowski, Heinrich Hartmann (2022)
    The knowledge ofthe structural and chemical properties of biochars is decisive for their application as technical products. For this reason, methods for the characterization of biochars that are generally applicable and allow quality control are highly desired. Several methods that have shown potential in other studies were used to investigate two activated carbons and seven biochars from different processes and feedstock. The chars were chosen to cover a wide range of chemical composition and structural properties as a hardness ...

  • Анализа рада дисконтинуалног система на основу симулације утовара и транспорта целог површинског копа

    Милош Јовановић (2024)
    У овом раду анализира се рад дисконтинуалног система утовара и транспорта на површинским коповима користећи софтверски пакет Haulsim. Циљ истраживања је побољшање ефикасности процеса транспорта и оптимизација коришћења ресурса. Симулација је спроведена за различите сценарије утовара и транспорта, укључујући варијације у броју возила, њиховој брзини, капацитету, као и рутама транспорта. Добијени резултати су показали значајне могућности за унапређење постојећих процедура и смањење трошкова. Дисконтинуални системи су сложени и захтевају пажљиву анализу како би се постигла максимална продуктивност и смањење ...

  • Granatski amfiboliti Bistrice

    Jovana Opančina (2024)
    Predmet ispitivanja ovog završnog rada su granatski amfiboliti Bistrice. Izvršena su petrografska i hemijska ispitivanja s ciljem da se odredi stepen metamorfizma, protolit ispitivanih stena i P-T uslovi nastanka. Ispitivani granatski amfiboliti geografski pripadaju Prijepolju, tačnije nalaze se na ulasku u Prijepolje, mesto Bistrica. Geološka građa obuhvata uglavnom mezozojske tvorevine među kojima se nalaze sedimentne, magmatske i metamorfne stene. Geološki procesi koji su doveli do stvaranja amfibolita su procesi subdukcije i obdukcije koji su se pretpostavljamo dešavali na većim ...

  • A Lexical Approach to Acronyms and their Definitions

    Cvetana Krstev, Duško Vitas, Ranka Stanković (2015)
    In this paper we present a comprehensive approach to acronyms for Natural-Language Processing (NLP) of Serbian texts. The proposed procedure includes extraction of acronyms and their definitions that are usual Multi-Word Units (MWUs), shallow parsing of MWUs that enables MWU lemmatization and production of entries in morphological electronic dictionaries, both for MWU and acronyms, that are provided with grammatical, syntactic, semantic and domain information. This approach enables representation that reflects complex relations between acronyms and their definitions.

  • Numerical Models of Debris Flows with Entrainment Analysis-Case Studies from the Republic of Serbia

    Jelka Krušić , Biljana Abolmasov, Miloš Marjanović (2021)
    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 ...

  • The optimization of auxiliary machinery in open-cast lignite mines: a case study of bulldozers

    Dragan Ignjatović, Predrag Jovančić, Stevan Đenadić, Ivan Janković, Ivica Ristović (2019)
    One of the most important prerequisites for the successful operation of the open-cast lignite mine is to carry out all the auxiliary works timely with the necessary quality. The most important and most commonly used auxiliary machines are bulldozers. Engaging time of bulldozers use is in direct relation with the coefficients of the time and capacity utilization of the continuous system for the excavation of coal and tailings, which indicates their importance. More than 100 bulldozers have been hired ...
