  • Industrija 4.0 - koncept prediktivnog održavanja 4.0 (PdM 4.0) u rudarstvu

    Predrag Jovančić, Vesna Damnjanović, Dragan Ignjatović, Miloš Tanasijević, Stevan Đenadić (2019)
    Četvrtu industrijsku revoluciju – Industriju 4.0 karakteriše upotreba cyber-fizičkih sistema. Da bi se postigla optimalna strategija održavanja (ali i eksploatacije), neophodno je razviti sisteme koji podržavaju napredne inteligentne sisteme održavanja ili tehnologije pametnog održavanja. Iz toga su proizašli postulati Prediktivnog održavanja 4.0 (PdM 4.0) koji definišu veoma blisku budućnost u oblasti održavanja tehničkih sistema pa i rudarske opreme. PdM 4.0 uključuje iskorišćenje snage veštačke inteligencije za stvaranje stalnog uvida u otkrivanje uzroka i anomalija u radu opreme, koje se ...

  • Heavy metals in lignite and soil of Kostolac-Kovin coal basin, eastern Serbia - comparative analysis with selected cities in Serbia, region, Europe and world

    Bogoljub Vučković, Bojan Dimitrijević (2023)
    The Kostolac-Kovin coal basin with an area of 320 km2, with 5 separate layers of coal and with a total of about 5.7 Bt of geological resources and reserves represents an exceptional potential for coal production in Serbia. The coal resources listed in this way are not fully exploitable, but they represent potential for consideration. In this paper, we deal with the geochemical characteristics of coal seams and perform a comparative analysis of coal affectation on the environment. With ...

  • Determining the Availability of Continuous Systems at Open Pits Applying Fuzzy Logic

    Miljan Gomilanović, Miloš Tanasijević, Saša Stepanović (2022)
    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 ...

  • Sastav i teksture minerala FeO-Fe2O3-TiO2 sistema u vulkanskim stenama i porfirskim ležištima bakra Borske metalogenetske zone

    Aleksandar Luković (2021)
    Proces obrazovanja minerala iz sistema FeO-Fe2O3-TiO2 u uzorcima vulkanskih stena i porfirskih orudnjenja borske zone prikazan kroz pojavu magnetita/hematita i njihovih alteracija. Minerali ove zone su ispitivani optičkim metodama (odbijena i propuštena svetlost), SEM-EDS/BSD, XRPD, LA-ICP-MS metodama. Rezultati ispitivanja su, pored glavnih Fe – Ti oksida, otkrili prisustvo ferijskog ilmenita u hornblenda andezitima I vulkanske faze kao i magnetita sa većim koncetracija Cr u zoni zlotske magnetne anomalije.

  • The use of biological markers in determination of origin and type of organic matter in the Tisza river sediments

    Snežana Štrbac, Gordana Gajica, Aleksandra Šajnović, Nebojša Vasić, Ksenija Stojanović, Branimir Jovančićević (2013)
    The objective of the study was to determine the origin and type of organic matter (OM) of the Tisza recent sediments along the distance of 153 km through the territory of Serbia. For this purpose group organic-geochemical parameters and biomarker compositions were used. All samples contain approximately same amount of OM, which was deposited under uniform, slightly reducing conditions. Based on the distribution of n-alkanes, the origin and type of OM could not be precisely estimated. However, n-alkane patterns ...

  • Uticaj površinske obrade kamena na promenu primarne poroznosti

    Ana Radivojević (2024)
    Površinska obrada kamena je izuzetno bitna kod stena koje se koriste u izgradnji svih vrsta objekata. Površinskom obradom se direktno utiče, ne samo na estetska svojstva kamena nego i na njegove fizičko-mehaničke karakteristike. Cilj ovog završnog rada je analiza uticaja poliranja i rezanja kao tehnoloških procesa obrade na poroznost odabranih vrsta arhitektonsko-građevinskog kamena. Ispitivane stene su gabro „Nero Assoluto“, granit sa površinskog kopa „Ploče“, granit African Red, krečnjak sa lokaliteta „Skržut“ i krečnjak poznat pod nazivom „Sirogojno crveni“.

U našem delu sveta pojavljuju se u okviru ultrakalijskih provincija u Španiji, Italiji, Srbiji, Makedoniji i Turskoj. U Srbiji su zastupljeni ponajviše u zapadnim delovima zemlje, oko opština Ljubovija i Mali Zvornik, ali i u široj okolini Rudnika, Kopaonika i u istočnoj Srbiji. Mnoga ispitivanja sprovedena su u rudnom polju Veliki Majdan u zapadnoj Srbiji sa čije jugoistočne strane protiče Kolarička reka. Ovaj lokalitet ...

TMK je nastaotokom kontinuirane vulkanske aktivnosti, koja je trajala oko deset miliona godina iodvijala se generalno u tri faze (Zimmerman et al., 2008, Kolb et al., 2013, Banješević,2006). Pomeranje vulkanskog fronta je išlo od istoka ka zapadu (von Quadt et al., 2002,2003, 2007).

    Kostić N. Bojan (2021)
    Kontaktni metamorfizam gornjokrednih sedimentnih stena na planini Rudnik ispitivan je na uzorcima iz pet bušotina. Definisano je šest varijeteta krednih stena (protolita) koji čine dve litološke jedinice izgrađene od klastičnog, karbonatnog i klastično-karbonatnog materijala. Vulkanskom aktivnosti na Rudniku formirana su vulkanska tela koja se utiskuju duž slojevitosti sedimentnih stena, a neka ih presecaju u vidu dajkova. Starost ovog vulkanskog događaja određena je na 23.9 miliona godina. Ovaj miocenski vulkanizam doveo je do kontaktno metamorfnih promena sedimentnih stena i obrazovanja skarnova ...

  • A WordNet Ontology in Improving Searches of Digital Dialect Dictionary

    Miljana Mladenović, Ranka Stanković, Cvetana Krstev (2017)
    In this paper, we present a method for automatic generation of a digital resource, which connects all indirect synonyms of a dialect term to all indirect synonyms of a corresponding term in the standard language, aiming to improve the search of a digital dialect dictionary. The method uses SWRL rules defined in the Serbian WordNet ontology to identify sets of synonymous words. It also uses e-dictionaries to produce correct lemmas in standard language that users usually employ in searches. ...
