  • Risk Evaluation: Brief Review and Innovation Model Based on Fuzzy Logic and MCDM

    Stevan Djenadic, Milos Tanasijevic, Predrag Jovancic, Dragan Ignjatovic, Dejan Petrovic, Ugljesa Bugaric (2022)
    The risk assessment of engineering systems represents an important part of the quality of service and dependability. The existing methods for risk evaluation use crisp sets for rating partial indicators’ proposition and their cumulative products as an overall indicator. In this paper, existing FMEA and FMECA methods have been improved using the fuzzy expert system for calculating the risk priority number. The application of fuzzy logic allows the use of linguistic descriptions for risk analysis. In this way, the ...

  • A bilingual digital library for academic and entrepreneurial knowledge management

    Ranka Stanković, Cvetana Krstev, Biljana Lazić, Dalibor Vorkapić (2015)
    A generic knowledge management process of organization, storage and retrieval of knowledge can suitably be fitted in a digital library. In the digital and knowledge age digital libraries can be used in knowledge management to handle intellectual assets and support knowledge creation. A multilingual digital library either stores content in more than one language or provides multilingual query access to monolingual content. In Serbia 18 of 308 scientific journals regularly published are bi-lingual, with papers simultaneously being in English ...

  • 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 ...

    Postavljeni konceptualni model hidrogeotermalnog sistema Brusa sa širom okolinom testiran je primenom različitih hidrohemijskih i izotopskih metoda u cilju njegove verifikacije i karakterizacije. Rezultati su ukazali na atomsfersko poreklo geotermalnih fluida i na razviće primarnih rezervoara u okviru karbonatnih stena. Prvi rezervoar formiran je u okviru krečnjaka gornjotrijakse starosti, dok drugi rezervoar egzistira u okviru trijskaih mermera. Zone prihranjivanja locirane su u zapadnom delu terena. Sistemi gravitacionih raseda kontrolišu kretanje fluida u sistemu, dok proces jonske izmene dominira u ...

  • Pokazatelji recentne tektonske aktivnosti u speleološkim objektima Dževrinske grede (istočna Srbija)

    Ana Mladenović, Jelena Ćalić (2022)
    Sistem Timočkog raseda predstavljen je sistemom desnih transkurentnih raseda generalnog pružanja sever – jug, koji su bili aktivni u periodu oligocena i miocena u okviru Karpato-balkanskog orogena. Početak njihove aktivnosti vezuje se za rotaciju tektonskih jedinica Karpato-balkanida (Dacia Mega Unit) oko rigidne Mezijske jedinice. Aktivnost ovih transkurentnih raseda je akomodirala ovu rotaciju, pa se smatra da je kumulativno kretanje duž Timočkog raseda tokom perioda njegove aktivnosti bilo do 100 km. Usled kompleksnih tektonskih rotacija, rasedi ovog sistema doveli su ...

  • Utilizing sewage wastewater heat in district heating systems in Serbia: effects on sustainability

    Marija Živković, Dejan Ivezić (2021)
    Transformation of the heating sector is recognized as being essential for ensuring reliable and afordable energy services provided with reduced consumption of energy sources and diminished impact on the environment and less import dependency. The possibility of utilizing energy sources that otherwise would be wasted needs to be considered and treated as a big advantage of district heating systems. Despite many advantages, sewage wastewater heat is still a mostly unused resource at the global level and a totally unused ...
