  • Дефинисање хидрауличког механизма истицања карстних подземних вода применом биваријантне анализе временских серија

    Вељко Мариновић (2022)
    Bivariate analysis was applied within the cross-correlation in time and the gain function as part of the cross-spectral function in the frequency domain, to the time series of precipitation and discharge of the Oko Bijela and Bosna karst springs in the period 2015-2020. Bivariate analysis showed a very fast reaction of the Oko Bijela spring and a reaction delay at the Bosna spring, which indicate a very weak amortization of the input signal within the Oko Bijela system and ...

  • Multi-Criteria Fuzzy-Stochastic Diffusion Model of Groundwater Control System Selection

    Dušan Polomčić, Zoran Gligorić, Dragoljub Bajić, Miloš Gligorić, Milanka Negovanović (2019)
    When considering data and parameters in hydrogeology, there are often questions of uncertainty, vagueness, and imprecision in terms of the quantity of spatial distribution. To overcome such problems, certain data may be subjectively expressed in the form of expert judgment, whereby a heuristic approach and the use of fuzzy logic are required. In this way, decision-making criteria relating to an optimal groundwater control system do not always have a numerical value. Groundwater control scenarios (alternatives) are identified through hydrodynamic ...

  • 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 ...

  • The ‘Umka’ landslide

    Uroš Đurić, Dragana Đurić, Miloš Marjanović, Biljana Abolmasov, Ivana Vasiljević (2024)
    We present an in-depth landslide map of the ‘Umka’ landslide near Belgrade, Serbia, at a scale of 1:5000. The map delineates elements at risk, primarily buildings and road infrastructure impacted by the landslide displacements of several cm per year, introduced during frequent reactivation stages. The Main map results from a survey of over 350 buildings and more than 7 km of state and local roads. The acquisition techniques included engineering geological field mapping, building survey, and visual interpretation of ...

  • Knowledge and Rule-Based Diacritic Restoration in Serbian

    Cvetana Krstev, Ranka Stanković, Duško Vitas (2018)
    In this paper we present a procedure for the restoration of diacritics in Serbian texts written using the degraded Latin alphabet. The procedure relies on the comprehensive lexical resources for Serbian: the morphological electronic dictionaries, the Corpus of Contemporary Serbian and local grammars. Dictionaries are used to identify possible candidates for the restoration, while the dataobtainedfromSrpKorandlocalgrammarsassistsinmakingadecisionbetween several candidates in cases of ambiguity. The evaluation results reveal that,dependingonthetext,accuracyrangesfrom95.03%to99.36%,whilethe precision (average 98.93%) is always higher than the recall (average 94.94%).

  • Uticaj voda Dunava na formiranje kvaliteta podzemnih voda u zoni Apatina

    Bojan Hajdin, Željko Kljajić, Vesna Ristić-Vakanjac, Milojko Lazić, Marina Čokorilo-Ilić (2018)
    Područje Apatina u proteklom periodu često je pominjano u razvojnim vodoprivrednim strategijama kao potencijalno perspektivna lokacija za izgradnju izvorišta duž obale Dunava, koje bi moglo da ima regionalni značaj. Ovim rešenjem trebao bi se prevazići problem lošeg kvaliteta vode za piće na celom području severne Bačke, tako što bi se kvalitet podzemne vode poboljšao zahvatanjem infiltriranih rečnih voda u priobalju Dunava.
