  • Using gravity data to define structural correlation affecting the formation of Neogene basins

    Snežana Ignjatović, Ivana Vasiljević, Branisav Sretković, Milanka Negovanović (2023)
    A gravity survey can help to define the structural correlation in the study area. The structures that have influenced the development of Neogene basins can be defined using gravity data. By applying mathematical transformations to gravity data, the geological structures (faults, nappes, etc.) that impacted the formation of Neogene basins can be defined. We have taken the part of the Dinarides as the test region. The paper presents the results obtained using the procedure residual, vertical gradient, and total ...

  • Defining location and dip of magnetic anomaly sources applying mathematical transformation

    Snežana Ignjatović, Milanka Negovanović (2022)
    It is significant to define the location and dip of anomaly sources during the geophysical exploration (magnetic, gravity, electric, seismic, etc.). In this paper we presented results obtained during magnetic survey. Applying different method of mathematical transformations on magnetic data we can find the position (edge) and dip of magnetic anomaly sources. For successful solution of this problem, we used combination two method tilt derivative and upward continuation. The study area located in the eastern Serbia, north part of ...

  • Digitalizacija u rudarstvu: Kreiranje sistema za efikasno poslovno izveštavanje

    Stevan Đenadić, Aleksandar Mirković, Veljko Rupar (2024)
    Proces donošenja odluka u oblasti rudarstva i geologije uslovljen je blagovremenim posedovanjem kvalitetnih podataka i informacija. Kompleksnost rudarskih procesa nalaže prikupljanje podataka na dnevnom odnosno na smenskom nivou. Podaci kao takvi bez analitičkog pristupa nisu dovoljni. Kako bi pristup podacima bio brz i efikasan neophodno je posedovanje adekvatnog digitalnog rešenja uz adekvatne centralizovane baze podataka. U ovom radu je dat pregled trenutne pozicije rudarstva sa aspekta digitalne transformacije kao i predlog jednostavnog prototipa u obliku digitalnog sistema za poslovno ...

  • Linearization of Input Signal as a Necessary Tool in Stochastic Modeling of Karst Groundwater

    Veljko Marinović (2021)
    Modelling of karst hydrogeological systems is a very complicated task, bearing in mind that for a deterministic model one should know the internal physical processes of precipitation transformation into discharge, while for a stochastic model nonlinear dynamic systems such as karst should be simulated by linear regression equations. Stochastic models need linearization of input time series due to often large residual in the recession period. This occur because the model is not able to absorb single rain episodes, which ...

  • Definisanje strukturnih odnosa primenom postupka horizontalni gradijent

    Snežana Ignjatović, Ivana Vasiljević, Natalija Jovanović (2019)
    Različiti postupci matematičkih transformacija se mogu primeniti na gravimetrijskim i magne tometrijskim podacima, kako bi se na istražnom terenu definisali strukturno-tektonski odnosi. U radu su prikazani rezultati dobijeni korišćenjem postupka horizontalni gradijent i ukupni horizontalni gradijent na gravimetrisjkim podacima. Navedeni postupci su pomogli da se detektuju kontakti sa velikim padnim uglom (vertikalni ili subvertikalni kontakti), koji se mogu interpretirati kao rasedi.

  • Possibilities for Reduction of Energy-Related Air Pollution in Serbia - Exploring Energy Scenarios

    Marija Živković, Boban Pavlović, Dejan Ivezić, Aleksandar Mijatović (2023)
    Fossil fuels and biomass account for almost 93% of the total primary energy supply in Serbia. Meeting the energy needs of consumers implies a transformation of the chemical energy of fuels through combustion processes to obtain heat that can be utilized as such, or further transformed into mechanical or electrical energy. These processes have an undeniable impact on air pollution, even in cases of biofuels or hydrogen combustion. Possibilities for air pollution reduction are identified, both on the supply ...
