  • Application of MCDA in the determination of optimal block size for open-pit modelling and mine planning

    Petar Marković, Dejan Stevanović, Milica Pešić Georgiadis, Mirjana Banković (2021)
    The process of creating a geological block model as the basis for a further detailed design and planning of mining operations is a very responsible task. Errors made during this initial process are transferred to all other phases of the mining project. Certainly, one of the most important decisions for the modelling process is the choice of the appropriate size of the blocks that form the model itself. The determination of the optimal block size is not a simple ...

  • Analysis Of the Process Of Carbon Capture Utilization And Storage In Underground Reservoirs

    John Nyame (2024)
    The importance of mitigating the effects of global climate change has necessitated an in-depth exploration of innovative strategies to reduce carbon dioxide (CO2) emissions. Among these strategies, Carbon Capture, Utilization, and Storage (CCUS) has emerged as a promising and transformative solution. This master thesis delves into the diverse realm of CCUS processes, aiming to unravel the positives challenges, and opportunities within this dynamic field. The analysis begins with a systematic examination of carbon capture technologies, encompassing post-combustion, pre-combustion, and oxy-fuel combustion ...

  • Parametri zbijanja komunalnog otpada određeni različitim laboratorijskim metodama

    Jovana M Janković Pantić, Dragoslav R Rakić, Irena G Basarić Ikodinović, Tina D Đurić, Snežana Bogdanović (2021)
    Zbijanje komunalnog otpada predstavlja jednu od osnovnih faza korišćenja komunalne deponije. Zbog toga je kao i kod drugih nasutih građevina, veoma korisno odrediti parametre zbijanja: maksimalnu suvu zapreminsku težinu (dmax) i optimalnu vlažnost (wopt). Dobijeni rezultati mogu da posluže prilikom projektovanja kapaciteta deponije kao i prilikom definisanja obradivosti otpada. U dosadašnjoj praksi najčešći način određivanja parametra zbijanja je standardna metoda (Proktorov opit) koja se koristi u mehanici tla, uz eventualnu redukciju energije zbijanja. Međutim, različiti tretmani komunalnog otpada na ...

  • Natural two-dimensional pyrophyllite: Nanoscale lubricant, electrical insulator and easily-machinable material

    Borislav Vasić, Radoš Gajić, Ivana Milošević, Žarko Medić, Marina Blagojev, Marko Opačić, Aleksandar Kremenović, Dejan Lazić (2022)
    Pyrophyllite, with the chemical formula Al2Si4O10(OH)2, is a naturally occurring and abundant van der Waals mineral belonging to the group of phyllosilicates. It is very soft, layered crystal used for sculpting and an excellent electrical and thermal insulator aimed for the operation at high pressure and temperature. Here, for the first time, two-dimensional (2D) pyrophyllite obtained by both mechanical and liquid phase exfoliation is presented and investigated at the nanoscale. The layered structure provides low friction coefficient of around ...

  • Oдређивање броја камиона за транспорт руде на површинском копу Шупља стијена

    Грујичић Стефан (2024)
    Транспорт на површинским коповима се одвија паралелнпо са осталим процесима екаплоатације. Како не би долазило до непредвиђениих трошкова, потребно је усагласити све системе производње. Димензионисање адекватног транспортног система обезбеђује максималну продуктивност механизације и профитабилну експлоатацију. Чињеница да трошкови транспорта заузимају знатан део укупних трошкова иде у прилог томе да је одређивање потребног броја камиона за превоз откопаног материјала од великог значаја.

  • Tektonska evolucija ugljevičkog basena (Bosna i Hercegovina)

    Slobodan Dragić (2024)
    U radu je prezentovana šira slika tektonske evolucije ugljevičkog basena, kao i Dinarida uopšte. Prikazani su litostratigrafski odnosi istraživanog područja, kao i kratak pregled tektonskih jedinica koje se nalaze u domenu basena. Najveća pažnja posvećena je kinematskoj analizi rasjednih struktura i interpretaciji podataka u svjetlu tektonske evolucije basena. Ugljevički basen zapunjen je oligocensko-miocenskim sedimentima, a njegovu osnovu grade paleozojsko-mezozojske formacije. Najstarije tvorevine na ovom području su permski sedimenti.

  • Frequency and Length of Syllables in Serbian

    Marija Radojičić, Biljana Lazić, Sebastijan Kaplar, Ranka Stanković, Ivan Obradović, Ján Mačutek, Lívia Leššová (2019)
    Basic analyses of several properties of syllables (the rank-frequency distribution, the distribution of length, and the relation between length and frequency) in Serbian is presented. The syllabification algorithm used combines the maximum onset principle and the sonority hierarchy. Results indicate that syllables behave similarly to words as far as mathematical models are concerned, but values of parameters in models for syllables are quite different from those for words.

Bratislava, Slovakia e-mail: livia.lessova@fmph.uniba.sk 8 It is quite common that there are several definitions of a linguistic unit (cf. e.g. Crystal, 2008, pp. 521-523 for word, p. 367 for phrase, and pp. 432-433 for sentence).

  • Determination of Mechanical Properties of Altered Dacite by Laboratory Methods

    Veljko Rupar, Vladimir Čebašek, Vladimir Milisavljević, Dejan Stevanović, Nikola Živanović (2021)
    This paper presents a methodology for determining the uniaxial and triaxial compressive strength of heterogeneous material composed of dacite (D) and altered dacite (AD). A zone of gradual transition from altered dacite to dacite was observed in the rock mass. The mechanical properties of the rock material in that zone were determined by laboratory tests of composite samples that consisted of rock material discs. However, the functional dependence on the strength parameter alteration of the rock material (UCS, intact ...

    Експлоатација нафте и гаса кључна је за задовољење глобалних енергетских потреба. Различите методе се користе за ефикасно вађење тих природних ресурса из земљe. Механичке методе експлоатације, које укључују различите врсте пумпи и компресора, играју значајну улогу у овом процесу. У нафтној индустрији, ефикасно вађење нафте и гаса зависи од избора одговарајуће технологије пумпања. Две од најраспрострањенијих технологија су дубинске пумпе са клипним шипкама (енгл.
