Preliminary impact assessment of No2 emission from a heating plant on air pollution: case of Zemun, Serbia
The aim of this paper is to provide a preliminary evaluation of the impact caused by NO2 emissions from a heating plant on the local air quality. To model the spatial distribution of NO2 emissions from the heating plant, the AERMOD model was employed. The evaluation was conducted by analyzing and contrasting the simulated NO2 concentration from the heating plant with the overall NO2 concentration recorded at the nearest monitoring station over the entire heating season. The study focused ...Boban Pavlović, Uroš Pantelić, Marija Živković, Dejan Ivezić.

Hybrid Model for Optimisation of Waste Dump Design and Site Selection in Open Pit Mining
Aleksandar Doderovic, Svetozar-Milan Doderovic, Sasa Stepanovic, Mirjana Bankovic, Dejan Stevanovic (2023)Waste management is an unavoidable technological operation in the process of raw material extraction. The main characteristic of this technological operation is the handling of large quantities of waste material, which can amount to several hundred million cubic metres. At the same time, this operation must comply with all administrative and environmental standards. Therefore, optimising waste rock management (particularly haulage and dumping) has the potential to significantly improve the overall value of the project. This paper presents a hybrid ...Aleksandar Doderovic, Svetozar-Milan Doderovic, Sasa Stepanovic, Mirjana Bankovic, Dejan Stevanovic.

Application of MCDA in the determination of optimal block size for open-pit modelling and mine planning
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 ...dimenzije minibloka, višekriterijumska analiza, AHP, modeliranje ležišta, planiranje na površinskim kopovimaPetar Marković, Dejan Stevanović, Milica Pešić Georgiadis, Mirjana Banković.

Against the tide: southeast to northwest shelf-edge progradation in the southeastern margin of Lake Pannon, Banat (Serbia and Romania)
In the late Neogene, the Pannonian Basin in Central Europe was filled with sediments when rivers from the Alps and Carpathians shed their sediment load into Lake Pannon. The most powerful source-to-sink system was that of the paleo-Danube, transporting sediments from the NW as far as the southeastern part of the lake. In the southeastern margin of the basin, however, local sedimentary systems worked in the opposite direction, against the “tide” of the prevailing N to S sediment transport. ...Dejan Radivojević, Miloš Radonjić, Lajos Tamás Katona, Imre Magyar.

Transition pathways of household heating in Serbia: Analysis based on an agent-based model
To explore pathways of the energy transition of household heating, an agent-based simulation model was developed for the case of the Serbian household sector. The model is focused on individual entities (households) with the objective to explore the effects of policy instruments on energy transition in households with individual heating systems. Empirically collected survey data were used as input for households’ attitudes towards sustainable heating. Simulations showed that the proposed instruments would lead to higher heating efficiency and less ...energetska tranzicija, modeliranje bazirano na agentima, sistemi grejanja, sektor domaćinstva, obnovljivi izvori energije, emisija CO2Boban Pavlović, Dejan Ivezić, Marija Živković.

Integrated energy planning approach for accelerating energy transition of households
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 ...Energetsko planiranje, Integrisano energetsko modeliranje, Energetska tranzicija, Domaćinstva, Individualno grejanje, LEAPBoban Pavlović, Marija Živković, Dejan Ivezić.

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.

Agent-based modeling as a support to an expert-based approach: Exploring individual heating systems transition
Expert-based energy scenarios are mainly developed following assumptions of experts and, in most cases, a limited number of stakeholders. Such an approach will provide satisfactory results in centrally managed energy sectors where further decisions could be envisaged relatively precisely (electricity production/distribution, district heating systems, etc.). The same approach will provide more uncertain outcomes of future energy structure in the household sector, where decisions related to consumption, selection of energy source, or application of specific technology are made by numerous ...Energetska tranzicija, Grejanje domaćinstava, Individualni sistemi grejanja, Energetsko planiranje, Integrisano energetsko planiranje, ABM, LEAP, SrbijaBoban Pavlović, Marija Živković, Dejan Ivezić.

Identification of the Best Available Renewable Energy Source for Electricity Production in Serbia
Around 2/3 of electricity production in Serbia originates from coal-fired thermal power plants. The most significant domestic coal deposits are lignite deposits, a type of low -quality coal that causes negative health, climate and environmental impacts during the combustion.

Komparativna analiza završnih kontura površinskog kopa Drmno
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.

Industrial Waste Heat Potential for Meeting Heat Demand in the Republic of Serbia
Dejan Ivezić, Marija Živković (2023)Finalna potrošnja energije u industrijskom sektoru čini skoro 25% finalne potrošnje energije u Republici Srbiji. Procenjuje se da je 50-70% potrošnje energije u industriji namenjeno proizvodnji toplotne energije u različitim industrijskim procesima. Deo proizvedene toplotne energije se nepovratno gubi kao energija odvedena u okolinu: prenosom toplote kroz zidove procesne opreme, dimnim gasovim, otpadnim vodama itd. Korišćenjem otpadne toplote povećava se efikasnost korišćenja primarne energije i smanjuje ukupna potreba za energijom. Otpadna toplota se može koristiti u samom industrijskom objektu ...Dejan Ivezić, Marija Živković.

Complex geophysical survey on solving the problem of water loss in the karst terrain reservoir
Branislav Sretković, Dejan Vučković (2023)Geophysical surveys in karst terrain are always a specific challenge. Each of them requires a careful consideration of the problem, specific conditions on the ground, the selection of adequate methods applicable in that specific and unique karst area. But they should have one thing in common: a complex approach and looking at the problem from wider to narrower, with a gradual narrowing of the investigation area, increasing the spatial precision and resolution of the obtained data. On the example of ...Branislav Sretković, Dejan Vučković.
