  • Automatic construction of a morphological dictionary of multi-word units

    Cvetana Krstev, Ranka Stanković, Ivan Obradović, Duško Vitas, Miloš Utvić (2010)
    The development of a comprehensive morphological dictionary of multi-word units for Serbian is a very demanding task, due to the complexity of Serbian morphology. Manual production of such a dictionary proved to be extremely time-consuming. In this paper we present a procedure that automatically produces dictionary lemmas for a given list of multi-word units. To accomplish this task the procedure relies on data in e-dictionaries of Serbian simple words, which are already well developed. We also offer an evaluation ...

    Analiza mogućnosti korišćenja podzemnih voda za potrebe vodosnabdevanje stanovništva kao i za navodnjavanje vršena je na prostoru sliva reke Ralje. Istražni prostor veličine oko 280 km2 je obuhvatio veći deo sliva reke Ralje koji se administrativno nalaze na području grada Beograda. Podzemne vode su glavni izvor za vodosnabdevanje i navodnjavanje u ovom području. Seoska naselja nemaju urađenu komunalnu infrastrukturu pa predstavljaju značajan faktor za degradaciju kvaliteta podzemnih voda na ovom području. U periodu 2012-2014 godine prikupljeno je 100 uzorka ...

  • Fuzzy optimization in hydrodynamic analysis of groundwater control systems: Case study of the pumping station “Bezdan 1”, Serbia

    Dragoljub Bajić, Dušan Polomčić (2014)
    A groundwater control system was designed to lower the water table and allow the pumping sta-tion “Bezdan 1” to be built. Based on a hydrodynamic analysis that suggested three alternative solutions, mul-ticriteria optimization was applied to select the best alternative. The fuzzy analytic hierarchy process methodwas used, based on triangular fuzzy numbers. An assessment of the various factors that influenced the selec-tion of the best alternative, as well as fuzzy optimization calculations, yielded the “weights” of the alternativesand the ...

  • Rezultati ispitivanja parametara čvrstoće i dinamičkih svojstava mermera i mogućnost njihove korelacije

    Jelena Majstorović-Necković, Vladimir Čebašek, Veljko Rupar (2023)
    Ispitivanja stena kao radne sredine, odnosno materijala sa kojim se gradi, na kome se gradi i u kome se gradi, svojom složenošću zahteva njeno svestrano izučavanje po velikom broju parametara. Zadatak Mehanike stena je da što bolje upozna ponašanje stenske mase i njenu otpornost na dejstvo pritiska, zatezanja i smicanja, kao i dinamičkih svojstava. Poznavanje navedenih parametara i njihova korelacija omogućavaju pouzdaniji izbor parametara za projektovanje danas sve zahtevnijih uslova kako podzemne, tako i površinske eksploatacije. U ovom radu ...

  • Развој модела употребног квалитета помоћне механизације на површинским коповима лигнита

    Драгица Јагодић Крунић (2021)
    Тренутно стање помоћне механизације на површинским коповима лигнита је незадовољавајуће узроковано пре свега старошћу и неблаговременом заменом машима услед чега је расположивост недовољна а трошкови експлоатације и одржавања високи. Тренутно стање и захтеви који се постављају пред ове машине указују на неопходност оптимизације процеса управљања помоћном механизацијом. Одређивање оптималног времена замене и преосталих могућности је најодговорнији управљачки задатак који треба да буде заснован на свеобухватном сагледавању економских, техничких и других узрочно последичних веза.

    Harmonični ekonomski razvoj svake zemlje u velikoj meri zavisi od dostupnosti sirovina, naročito mineralnih sirovina. Obezbeđivanje njihove dovoljne količine na tržištu (ponude) je od vitalnog značaja za funkcionisanje različitih industrijskih grana koje proizvode različitu robu i opremu neophodnu za ispunjavanje životnih potreba stanovništva kao i za efikasnu poljoprivredu. Mineralne sirovine su neophodne za podršku ekonomskim aktivnostima na lokalnom, regionalnom, nacionalnom i međunarodnom nivou. Ovo su, istorijski, prve sirovine koje su počele da se koriste iz domaćih izvora, i u ...
