  • Model upravljanja investicionim projektima otvaranja površinskih kopova uglja

    Cvjetko P. Stojanović (2015-04-27)

    Gubitak isplake predstavlja nekontrolisano isticanje bušaćeg fluida kroz formacije kao što su kaverne, pukotine, ili drugi slojevi. Tradicionalne metode procene gubitka isplake se zasnivaju na primeni seizmičkih podataka ili pronalasku „mesta“ gubitka isplake na osnovu raspoloživih podataka iz susednih bušotina. Međutim, ove metode procene nisu pouzdane.‘ U disertaciji je izvršena analiza i procena uticaja parametara bušenja, geoloških faktora, karakteristika formacije i fluida na gubitak isplake kao i na formiranje fraktura u formacijama. Uspostavljeni su modeli koji podrazumevaju proces obrade ...

  • Determining the Groundwater Balance and Radius of Influence Using Hydrodynamic Modeling: the Case Study of the Groundwater Source “Šumice” (Kikinda, Serbia)

    Dušan Polomčić, Dragoljub Bajić, Jelena Zarić (2015)
    A groundwater flow model was developed to simulate groundwater extraction from the public water supply source of the City of Kikinda. The hydrodynamic model includes the municipal groundwater source of Kikinda (Šumice and the Jezero Well), but also an extended area where there are groundwater sources that provide water supply to three factories: (MSK, TM and LŽT - Kikinda). Hydrodynamic modeling, based on the numerical method of finite differences will show the groundwater balance of the sources in the ...

  • From DELA Based Dictionary to Leximirka Lexical Database

    Biljana Lazić, Mihailo Škorić (2020)
    In this paper, we will present an approach in transforming Serbian language Morphological dictionaries from a DELA text format to a lexical database dubbed Leximirka. Considering the benefits of storing data within a database when compared to storing them in textual documents, we will outline some of the functionality that the database has made possible. We will also show how hand-made rules that use category labels lexical entries are marked with can be used to link lexical entries. ...

  • Development and Evaluation of Three Named Entity Recognition Systems for Serbian - The Case of Personal Names

    Branislava Šandrih, Cvetana Krstev, Ranka Stanković (2019)
    In this paper we present a rule- and lexicon-based system for the recognition of Named Entities (NE) in Serbian news paper texts that was used to prepare a gold standard annotated with personal names. It was further used to prepare training sets for four different levels of annota tion, which were further used to train two Named Entity Recognition (NER) sys tems: Stanford and spaCy. All obtained models, together with a rule- and lexicon based system were evaluated on ...

  • The challenges for Z-generation geologists

    Dejan Radivojević (2022)
    Nastupajuća generacija geologa suočava se sa nekim problemima koji su poznati i njihovim prethodnicima, ali takođe i sa do sada novim i nepoznatim izazovima. Činjenica da mnogi geologiju povezuju sa „prljavim“ industrijama u kojima će biti sve manje prilika za zaposlenje u vreme kada se teži čistoj vodi, zemljištu i vazduhu kao i to da je smatraju zastarelom u sadašnje vreme brzog tehnološkog razvoja dovela je do velikog pada interesovanja za studije geologije svuda u svetu. Neophodno je još ...

  • Енергетска транзиција система даљинског грејања - могућности и изазови

    Марија Живковић, Дејан Ивезић (2023)
    Највише енергије у зградама у Србији троши се на загревање простора. Због тога ће системи даљинског грејања имати важну улогу у процесу транзиције целокупног енергетског сектора. Мере и активности морају да буду усмерене и на потрошњу и производњу енергије. У раду је дат преглед потенцијала различитих обновљивих и алтернативних извора енергије, који се могу користити за производњу топлотне енергије. Приказани резултати су приказани са различитим нивоом детаљности, у зависности од расположивих података, а који могу да служе као ...
