    Ana S. Mladenović (2015-06-19)
    Циљ ове докторске дисертације био је реконструкција еволуције напонског пољаЗемљине коре у подручју Интерних Динарида у Србији током Алпске орогенезе.Истраживања за потребе решавања овог проблема су изведена у два дела. Првидео обухватао је анализу палеонапона на дефинисаном подручју истраживања,док се други део односио на анализу тренутно активног поља напона у овом делуБалканског полуострва. Истраживано подручје обухвата унутрашњи деоДинарског орогеног појаса, који се простире у централној и западној Србији. Собзиром на циљ истраживања, истраживано подручје је дефинисано тако даобухвата три ...

    Славко Тодић (2024)
    Овај завршни рад заснива се на испитивању могућности флотирања церузитне руде из лежишта Олово - БиХ. У циљу свеобухватног испитивања и добијања што прецизнијих резултата, у општем делу рада представљени су географски положај и историјат, како рудника, тако и општине Олово, затим геолошка грађа подручја, минерални састав лежишта и његове структурно-текстурне карактеристике. Такође, у овом делу рада дат је и кратак увид у минералошку анализу руде из лежишта Олово, те опште карактеристике корисних минерала церузита/англезита и калцита као основне некорисне ...

  • Using Lexical Resources for Irony and Sarcasm Classification

    Miljana Mladenović, Cvetana Krstev, Jelena Mitrović, Ranka Stanković (2017)
    The paper presents a language dependent model for classification of statements into ironic and non-ironic. The model uses various language resources: morphological dictionaries, sentiment lexicon, lexicon of markers and a WordNet based ontology. This approach uses various features: antonymous pairs obtained using the reasoning rules over the Serbian WordNet ontology (R), antonymous pairs in which one member has positive sentiment polarity (PPR), polarity of positive sentiment words (PSP), ordered sequence of sentiment tags (OSA), Part-of-Speech tags of words (POS) ...

  • Evaluation of the effects of wastewater heat pump integration into district heating systems by simulation

    Dejan Ivezić, Marija Živković, Dimitrije Manić, Aleksandar Madžarević, Boban Pavlović, Dušan Danilović (2023)
    The integration of wastewater heat pumps (using purified water) in district heating systems is analyzed in this paper. The simulation procedure is proposed to analyze the impacts of stochasticity of purified water temperature and flow to heat pump integration and operation. The analysis includes calculation of the daily and seasonal coefficient of performance, as well as fossil fuel savings and CO2 emission reduction due to wastewater heat pump use. The proposed procedure is implemented for the case study in ...

  • E-Connecting Balkan Languages

    Cvetana Krstev, Ranka Stanković, Duško Vitas, Svetla Koeva (2009)
    In this paper we present a versatile language processing tool that can be successfully used for many Balkan languages. This tool relies for its work on several sophisticated textual and lexical resources that were developed for most of Balkan languages. These resources are based on several de facto standards in natural language processing.

    Geophysical logging measurements for determining the condition of the rock mass on the dam profile and locating the predisposed directions of water circulation and loss from the reservoir were conducted in four boreholes distributed at a close distance. The survey was carried out in a typical karst terrain, which is an additional challenge for defining the geological model, especially in terms of water retention. That kind of data set provides an excellent opportunity for a new approach to analysis ...
