  • 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 ...

  • Održivi razvoj rudarskog sektora

    Vladimir Pavlović, Dragan Ignjatović, Tomislav Šubaranović (2022)
    Imajući u vidu sve veću zabrinutost za stanje životne sredine i socioekonomsku nejednakost, sektorska održivost bez obzira na privrednu delatnost, privlači sve veću pažnju kako globalno tako i lokalno. U tom smislu postoji konsenzus kod svih zainteresovanih strana da čovečanstvo treba da usvoji mere za promenu trenutno neodrživih obrazaca proizvodnje i potrošnje. Rudarska industrija igra fundamentalnu ulogu u ovom kontekstu, privlačeći pažnju kroz različite inicijative tokom poslednjih decenija. Neke od njih su čak i primenjene u praksi ali konsenzus ...

  • Pećina Peštera kod Laznice - primer razvića speleoloških objekata u zoni raseda (rasednoj breči)

    Mihajlo Mandić, Ana Mladenović (2022)
    Pećina Peštera se nalazi istočno od sela Laznica kod Žagubice. Iako lako pristupačna za posetioce i istraživače, do sada nije bila predmet detaljnijih istraživanja. Pominje se samo u prikazu arheološki interesantnih objekata okoline Žagubice, ali sa svedenim i uglavnom netačnim podacima o morfološkim karakteristikama. Speleološki značaj joj daje, pored relativno velikih dimenzija dvorane, njen razvoj u tektonski veoma oštećenoj zoni ukrštanja dva raseda što za posledicu ima potpunu dezintegraciju stenske mase u breču. Proces karstifikacije breče formira specifične morfološke ...

  • Karst groundwater quantity assessment and sustainability: the approach appropriate for river basin management plans

    Veljko Marinović, Zoran Stevanović (2019)
    As a result of the fact that karstified rocks can accumulate large amounts of high-quality groundwater, karst aquifer is considered, throughout the world, one of the most important types of aquifers. Due to their high permeability, but also vulnerability to pollution, these precious groundwater resources need to be properly evaluated and protected. Taking into account heterogeneity and complexity of the karst environment, it is difficult to propose a uniform algorithm for managing karst groundwater, which causes the necessity to ...

  • Rule-based Automatic Multi-word Term Extraction and Lemmatization

    Ranka Stanković, Cvetana Krstev, Ivan Obradović, Biljana Lazić, Aleksandra Trtovac (2016)
    In this paper we present a rule-based method for multi-word term extraction that relies on extensive lexical resources in the form of electronic dictionaries and finite-state transducers for modelling various syntactic structures of multi-word terms. The same technology is used for lemmatization of extracted multi-word terms, which is unavoidable for highly inflected languages in order to pass extracted data to evaluators and subsequently to terminological e-dictionaries and databases. The approach is illustrated on a corpus of Serbian texts from ...

  • Integrated energy planning approach for accelerating energy transition of households

    Boban Pavlović, Marija Živković, Dejan Ivezić (2023)
    The success of energy transition planning depends on several influential and variable factors that need to be considered and tracked in modeling to support policymakers. Expert-based energy models are mainly developed following the assumptions of experts and, in most cases, a limited number of stakeholders. This top-down modeling approach will provide satisfactory results in centrally managed energy sectors (electricity generation and distribution, district heating, etc.), where further decisions could be projected relatively precisely. However, the same approach will not ...
