Metodologija proračuna sanacije klizišta šipovima
Klizišta u Srbiji, u najvećem broju slučajeva, jako zavise od geoloških uslova u terenu i svako klizište ima svoje specifičnosti koje moraju da se odrede geotehničkim istraživanjima. Stoga su u radu prvo prikazane osnovne karakteristike klizišta u Srbiji, kao i postupci njihovog istraživanja. Zatim su prikazani proračuni sanacije klizišta vertikalnim šipovima. Metodologija proračuna je složena, jer podrazumeva interakciju klizišta i stabilizirajućih šipova. Prilikom određivanja bočne otpornosti tla oko šipova koristi se metoda Brinč Hansena koja uzima u obzir trodimenzionalne ...klizišta, geotehnička istraživanja, bočna nosivost šipova, interakcija klizišta i šipa, analiza stabilnostiSlobodan Ćorić, Dragoslav Rakić, Stanko Ćorić, Dušan Berisavljević.

Estimating hydraulic parameters for the complex hydrodynamic models
Hydrodynamic models have usually been calibrated manually, by trial-and-error, with different values of hydraulic parameters and hydraulic characteristics of boundary conditions. This method of calibration and estimation of hydraulic parameters requires an extensive knowledge and experience of experts, but whether the resulting solution includes an optimal set of parameters still remains an open question. An optimization method founded upon the Gauss-Marquardt-Levenberg algorithm, along with PEST software based on that algorithm, introduces automation of model calibration with regularization, which substantially ...Dušan Polomčić, Dragoljub Bajić, Jelena Ratković, Bojan Hajdin.

Effect of natural gas composition on methane number: A case of gas reservoirs in Serbia
Natural gas is considered as the most environmentally acceptable fossil fuel, thus it is an alternative to petroleum derivate, dominantly used in internal combustion engines. Physical properties of a fuel as well as behavior during combustion process are affected by its composition.

Uticaj starosti i sastava komunalnog otpada na zbijanje
Bez obzira na mogućnost da se komunalni otpad koristi kao sirovina, u Srbiji je i dalje osnovni vid odlaganja na komunalne deponije. Iako je odlaganje na deponije prema hijerarhiji otpada najnepovoljnije rešenje, u odnosu na ranije formirana smetilišta i neuređene deponije, ipak se sistemski dolazi do prikupljanja podataka, što se može smatrati poboljšanjem prakse.
