  • Geotehnički aspekti izgradnje visećeg pešačkog mosta u Starom gradu u Užicu

    Zoran Berisavljević, Miloš Marjanović, Uroš Đurić (2023.)
    U radu su prikazani rezultati geotehničkih istraživanja za potrebe izgradnje visećeg pešačkog mosta preko klisure reke Đetinje u Užicu. Predviđeno je da most, sistema prednapregnute trake, omogući prelaz pešacima sa desne dolinske strane na stranu Starog grada, koja je opasana strmom liticom (cca. 40 m visine). Za potrebe formiranja geotehničkog modela i strukturnog sklopa krečnjačke stenske mase korišćen je postupak fotogrametrijskog snimanja dronom. Predviđeno je da se zatežuća sila (od oko 30 MN), koju most prenosi na obalni stub, ...

  • The oil industry and climate changes

    Dejan Radivojević (2020)
    Uprkos tome što je problem klimatskih promena poznat dugi niz godina i dalje veliki broj ljudi poistovećuje pojam vremenskih prilika sa klimom ne uzimajući u obzir različitu dužinu njihovog trajanja. U medijima se vrlo često mogu naći katastrofična predviđanja vezana za zagrevanje naše planete usled neodgovornog ponašanja čoveka. Sa druge strane geolozi znaju da je tokom geološke prošlosti naše planete bilo mnogo toplijih intervala od današnjih kao i da ti intervali nisu neminovno rezultovali masovnim izumiranjem živog sveta već su ...

  • Adaptive neuro-fuzzy prediction of operation of the bucket wheel drive based on wear of cutting elements

    Filip Miletić, Predrag D. Jovančić, Milos Milovančević, Dragan Ignjatović (2020)
    The capacity of the rotor excavator depends largely on the operation of the subsystem for digging. There is a great contribution to the correct and sharp teeth when the capacity is the highest. In the function of time, the teeth become clogged due to abrasive wear, or changes in their geometric shape. To analyze the bucket wheel drive in depend on wear of the cutting elements in this study adaptive neuro fuzzy inference system (ANFIS) approach was implemented. ANFIS ...

  • Modeliranje buke u zoni površinskog kopa Ljubija ležišta Ciganuša - Škorac

    Teodora Kaličanin (2024)
    Svaki neželjeni zvuk u prirodi se može definisati kao buka. Buka svakodnevno utiče na ljude i predstavlja pretnju po ljudsko zdravalje. Zbog toga su nastale mnoge metode za merenje, proračun i saniranje ovog problema.Tema ovog završnog rada master studija je modeliranje buke u zoni površinskog kopa ''Ljubija''. Opisani su pojam buke i zvuka kao osnov za kasnije iznesene podatke, kao i tipovi i različiti izvori buke. Prikazane su metode merenja buke i uređaji koji se u tom procesu koriste. Obrađen ...

  • Analiza primenjenih metoda za transport parafinske nafte

    Dunja Milojević (2024)
    Sadržaj parafina u nafti ima dominantan uticaj na svojstva parafinskih nafti. Taloženje parafina, odnosno taloženje čvrstih čestica parafinskog voska, predstavlja ozbiljan globalni problem tokom proizvodnje i transporta sirove nafte. Samo taloženje voska zavisi od termodinamičkih faktora, poput temperature, pritiska i sastava nafte. Transport nafte cevovodima je uobičajeni proces transporta u naftnoj industriji. Kada prilikom cevovodnog transporta parafinske sirove nafte, dođe do prekida protoka i hlađenja nafte ispod temperature stinjavanja, parafini će kristalisati, pri čemu će doći do, geliranja celokupne transportovane ...

  • The different approaches in seismic stratigraphy interpretation

    Dejan Radivojević (2018)
    U tekstu su prikazana dva osnovna pristupa u seizmostratigrafskoj interpretaciji. Prvi kao polaznu osnovu ima seizmičke sekcije, čija se interpretacija u kasnijoj fazi koreliše sa bušotinskim podacima. Drugi u prvoj fazi analizira podatke dobijene dubokim bušenjem koji se kasnije korelišu sa seizmičkim sekcijama. Prikazan je hronološki redosled i objašnjen postupak pri seizmostratigrafskoj interpretaciji oba pristupa. Ovakav način interpretacije omogućio je naftnim kompanijama detaljnije i preciznije sagledavanje geoloških odnosa, smanjenje rizika istraživanja i racionalnije projektovanje razradnih bušotina.
