Značaj izvodjenja Proktorovog opita na komunalnom otpadu
Komunalni otpad predstavlja jedan od ključnih problema današnjice. U Srbiji je najčešći vid odlaganja otpada na komunalne deponije i zbog toga je bitno ispravno i sigurno ga skladištiti. Zbijanje komunalnog otpada predstavlja jednu od osnovnih komponenti procesa odlaganja. Kako bi se što bolje predvidelo ponašanje komunalnog otpada neophodno je pre zbijanja na terenu laboratorijski odrediti maksimalnu suvu zapreminsku težinu i optimalnu vlažnost. U dosadašnjoj praksi u svetu za to se koristi standardizovan Proktorov opit. U radu će biti prikazani ...... Geoenvironmental Engineering, Vol. 136, No. 8. 2010.

Geostatički proračuni sanacije klizišta šipovima
U ovom radu su, polazeći od rezultata geotehničkih istraživanja, prikazani geostatički proračuni sanacije klizišta vertikalnim šipovima. Metodologija proračuna je složena, jer podrazumeva interakciju klizišta i stabilizirajućih šipova. Stoga se simultano analiziraju stabilnost klizišta i stabilnost šipova. Prilikom određivanja bočne otpornosti tla oko šipova koristi se metoda Brinč Hansena koja uzima u obzir trodimenzionalne uslove u tlu i može da se primeni u složenim geološkim uslovima koji su česti u Srbiji. Analize stabilnosti klizišta vrše se odgovarajućim metodama granične ravnoteže. ...sanacija klizišta, interakcija klizišta i šipa, bočna otpornost šipova, stabilnost klizišta i šipova... 180 7 Н нег i и e = 20 / Д MO рњ О 80 – и јуч / — m __ ју /_„·–, / / рИ ти / з0г ___ __ —> 61.4 10 2 е 257 р K / — рИИИ li — 9.91 K 40 — 250 —y 36.8 q ___ 207 с и 5/ —_ — 5.88 20 | ——— — 24,5 — 15? _а ——— "C —— 17.6 / _— —|s e _J ___M00 __ ______„ljaž 2 РЖИ њ 10 — 5 7___ 40.2 / -_'__ ...Slobodan Ćorić, Dragoslav Rakić, Dušan Berisavljević.

Prioritization of strategic measures for strengthening the security of supply of the Serbian natural gas sector
To strengthen the security of supply of the Serbian gas sector, it is necessary to analyze the impact of planned strategic measures. The analysis involves the identification of the most influential threats to the security of natural gas supply and prioritization of the strategic measures for overcoming the consequences of threats. The proposed methodology is based on Fuzzy Analytic Hierarchy Process. The obtained weights for the identified threats and strategic measures are formed according to experts' judgments.

Rule-based Automatic Multi-word Term Extraction and Lemmatization
In this paper we present a rule-based method for multi-word term extraction that relies on extensive lexical resources in the form of electronic dictionaries and finite-state transducers for modelling various syntactic structures of multi-word terms. The same technology is used for lemmatization of extracted multi-word terms, which is unavoidable for highly inflected languages in order to pass extracted data to evaluators and subsequently to terminological e-dictionaries and databases. The approach is illustrated on a corpus of Serbian texts from ...... (2015). Automatic Construction of a TMF Terminological Database Using a Transducer Cascade. In Proc. of RANLP, pp. 17--23.

Improving efficiency of thermal power plants through mine coal quality planning and control
Главни циљ контроле квалитета угља у рудницима лигнита је снабдевање термоелектрана угљем чији квалитет мора да се креће унутар одређених квалитативних ограничења. Карактеристике угља могу да утичу на ефикасност, поузданост и расположивост како котла тако и јединица за контролу емисије. У овом раду аутори су презентовали интегрисану симулацију рударског процеса као нови приступ у истраживању променљивости калоричне вредности угља приликом експлоатације комплексног лежишта лигнита.

Determining the Groundwater Balance and Radius of Influence Using Hydrodynamic Modeling: the Case Study of the Groundwater Source “Šumice” (Kikinda, Serbia)
A groundwater flow model was developed to simulate groundwater extraction from the public water supply source of the City of Kikinda. The hydrodynamic model includes the municipal groundwater source of Kikinda (Šumice and the Jezero Well), but also an extended area where there are groundwater sources that provide water supply to three factories: (MSK, TM and LŽT - Kikinda).
