  • Keyword-Based Search on Bilingual Digital Libraries

    Ranka Stanković, Cvetana Krstev, Duško Vitas, Nikola Vulović, Olivera Kitanović (2017)
    This paper outlines the main features of Biblisha, a tool that offers various possibilities of enhancing queries submitted to large collections of aligned parallel text residing in bilingual digital library. Biblishsa supports keyword queries as an intuitive way of specifying information needs. The keyword queries initiated, in Serbian or English, can be expanded, both semantically, morphologically and in other language, using different supporting monolingual and bilingual resources. Terminological and lexical resources are of various types, such as wordnets, electronic ...

  • Strategic Environmental Assessment in the Application of Preventive Protection for Wind Farm Noise—Case Study: Maestrale Ring Wind Farm

    Boško D. Josimović, Aleksandar Cvjetić, Božidar Manić (2021)
    Determining the spatial position of wind turbines is the initial and most important phase in the development of a wind farm project. In this sensitive phase, all potential problems that may arise in the later stages of project development should be prevented by means of spatial and urban planning instruments. This makes it possible to achieve maximum use of the potential of wind in a particular space and, thus, fulfil the technical and economic requirements of the project while ...

  • The Fuzzy–AHP Synthesis Model for Energy Security Assessment of the Serbian Natural Gas Sector

    Aleksandar R. Madžarević, Dejan D. Ivezić, Miloš L. Tanasijević, Marija A. Živković (2020)
    Natural gas is used for the production of almost 20% of total energy today. The natural gas security of the Republic of Serbia is an urgent strategic, political and security issue. Serbia is one of the most vulnerable countries in Southeast Europe, because it only has one supply route. This study is a contribution to efforts to better understand the factors affecting energy security through the implementation of a new methodology based on the fuzzy–AHP synthesis model for measuring ...

  • Development and evaluation of fracture gradient curve model: a case study of south-central Kazakhstan

    Branimir Stanisavljevic, Vesna Karovic Maricic, Irena Isakov (2022)
    An accurate fracture gradient value is one of the most important issues in oil and gas well design and drilling. The value of a fracture gradient is a critical parameter for determining the drilling mud weight and selecting the proper depths for setting the casing in the planning process of drilling operations. This paper proposed the new curve model of fracture gradient for the south-central Kazakhstan (central Asia) region based on the analysis of leak-off test and format integrity ...

  • The shear strength evaluation of rough and infilled joints and its indications for stability of rock cutting in schist rock mass

    Dušan Berisavljević, Zoran Berisavljević, Svetlana Melentijević (2022)
    Construction of E75 highway section through Grdelica gorge was one of the most demanding projects realized in recent Serbian history. The alignment approximately 25 km long consists of several tens of bridges, two tunnels, three galleries and cuts with total length of 6 km. The alignment passes through highly anisotropic Palaeozoic schist rock formation of different weathering grades. This study focuses on shear strength properties of discontinuities, which are found to be the critical feature contributing to the occurrence ...

  • Energetska bezbednost sektora prirodnog gasa Srbije

    Aleksandar Madžarević, Predrag Jovančić, Miroslav Crnogorac (2023)
    U prve dve decenije 21. veka obezbeđivanje sigurnosti snabdevanja prirodnim gasom domaćeg tržišta bio je jedan od prioriteta razvoja energetike Srbije. Istovremeno, aspekt sigurnog snabdevanja bio je neizostavni deo slagalice stvaranja energetske bezbednosti. Izražena uvozna zavisnost je dominantna karakteristika sektora prirodnog gasa, tačnije, Republika Srbija je snažno zavisna od ruskog gasa, sa više od 80% uvezenih količina gasa, a do pre dve godine snabdevala se isključivo kroz jednu interkonekciju. U radu se razmatra aktuelna situacija u sektoru prirodnog ...

  • Available technological procedures for capturing CO2 in the industrial and power generation sectors

    Lola Tomić, Vesna Karović Maričić, Dušan Danilović, Branko Leković, Miroslav Crnogorac (2021)
    Climate change is a major environmental issue caused by anthropogenic emissions of greenhouse gases. Capturing CO2 and storing it in suitable geological formations is one of the main technological solutions that can provide mitigation of CO2 emission into the atmosphere. Capturing CO2 represents the first phase in process of carbon capture and storage, and includes the application of various technologies for the separation of CO2 produced in the energy and industrial sectors. There are four main systems for capturing ...

  • 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 ...

  • Tehno-ekonomska analiza varijanti sistema odvodnjavanja površinskog kopa Drmno od podzemnih voda do kraja eksploatacije

    Tomislav Šubaranović, Dušan Polomčić, Vladimir Pavlović (2018)
    Odvodnjavanje površinskog kopa Drmno od podzemnih voda je jedan od najznačajnijih podsistema u procesu eksploatacije u veoma zavodnjenoj radnoj sredini Kostolačkog basena uglja. Već od 2006. godine, Inovirani dugoročni program razvoja eksploatacije uglja predviđa izradu ekrana, pored zadržavanja postojećih standardnih metoda odvodnjavanja od podzemnih voda linijama bunara. Iako je kasnijim Glavnim rudarskim projektom, takođe, bila predviđena izrada ekrana, njegova realizacija nije započela. Na osnovu realnog sagledavanja postojeće projektne dokumentacije, početak izrade ekrana se predviđa od 2023. godine. ...

  • 100th Anniversary of the Carpathian-Balkan Geological Association (CBGA)

    Ljupko Rundić (2022)
    Током 22. конгреса Карпатско-балканске геолошке асоцијације (KБГА) одржаног у Пловдиву, Бугарска (7–11. Септембар, 2022) обележена je стогодишњица оснивања KБГА. Резолуција о оснивању „Карпатске геолошке асоцијације“ усвојена је на 13. Међународног геолошком конгресу у Бриселу, 19. августа 1922.године. То је био резултат ранијих напора и иницијативе Р. Кетнера (Чехословачка), Ј. Новака (Пољска), Г. Мунтеану Мургочија (Румунија) и В. Петковића (Југославија). Касније, после Другог светског рата, асоцијација мења назив у „Карпатско-балканска геолошка асоцијација (КБГА) “. Током протеклих 100 година, КБГА је ...

  • Komparativna analiza završnih kontura površinskog kopa Drmno

    Dejan Stevanović, Dragan Ignjatović, Tomislav Šubaranović, Mirjana Banković, Petar Marković (2022)
    Definisanje optimalne završne konture površinskog kopa od suštinskog je značaja za ostvarivanje strateških ciljeva u razvoju rudarskih projekata. Savremeni programski paketi i metode za optimizaciju granica kopa, zasnivaju se na pronalasku završne konture koja obezbeđuje maksimalan profit. U slučaju površinskih kopova uglja, kod kojih osim profita postoji i čitav niz dodatnih kriterijuma i strateških ciljeva, princip optimizacije granica prema profitu, najčešće nije u potpunosti primenjiv. Iz rog razloga za uspešno definisanje granica površinskih kopova, neophodno je sagledati čitavu lepezu ...
