Uticaj voda Dunava na formiranje kvaliteta podzemnih voda u zoni Apatina
Područje Apatina u proteklom periodu često je pominjano u razvojnim vodoprivrednim strategijama kao potencijalno perspektivna lokacija za izgradnju izvorišta duž obale Dunava, koje bi moglo da ima regionalni značaj. Ovim rešenjem trebao bi se prevazići problem lošeg kvaliteta vode za piće na celom području severne Bačke, tako što bi se kvalitet podzemne vode poboljšao zahvatanjem infiltriranih rečnih voda u priobalju Dunava. Istraživanjima koja je Departman za hidrogeologiju, Rudarsko-geo¬loškog fakulteta vršio tokom poslednjih 13 godina na izvorištima za vodosnabdevanje grada ...Bojan Hajdin, Željko Kljajić, Vesna Ristić-Vakanjac, Milojko Lazić, Marina Čokorilo-Ilić.

The impact of temporal variability of groundwater levels on groundwater vulnerability maps in karst terrains – a case example of the Perućac spring catchment area
Groundwater vulnerability maps represent an essential tool for protecting karst groundwater resources. Vulnerability assessment is usually based on spatial evaluation of various parameters that affect the vulnerability degree and regulate the protection role of the unsaturated zone. Most of these parameters, like soil and geology conditions, are constant and do not change during the year or over several years. In contrast, some parameters, such as the groundwater level, depend on the variability of recharge conditions. By considering the variability ...Vladimir Živanović, Igor Jemcov, Nebojša Atanacković.

Optimizacija faznog razvoja Površinskog kopa Ciganuša – Škorac u cilju definisanja dugoročne dinamike eksploatcije
Definisanje dugoročne dinamike razvoja rudarskih radova koja je u potpunosti usaglašena sa strateškim ciljevima Investitora, veoma je zahtevan zadatak, koji vrlo često podrazumeva veliki broj ograničenja. Adekvatno definisana dinamika razvoja rudarskih radova treba da obezbedi dugoročne zahteve u pogledu kapaciteta, kvaliteta i raspodele resursa neophodnih za ispunjavanje strateških ciljeva, koji se po pravilu svode na ostvarenje maksimalnog profita. Uspešno definisanje dinamike eksploatacije (posebno kod metaličnih ležišta) u najvećoj meri zavisi od optimizacije faznog razvoja površinskog kopa, odnosno od pravilnog ...Dejan Stevanović, Petar Marković, Mirjana Banković, Milan Živković.

A Lexical Approach to Acronyms and their Definitions
In this paper we present a comprehensive approach to acronyms for Natural-Language Processing (NLP) of Serbian texts. The proposed procedure includes extraction of acronyms and their definitions that are usual Multi-Word Units (MWUs), shallow parsing of MWUs that enables MWU lemmatization and production of entries in morphological electronic dictionaries, both for MWU and acronyms, that are provided with grammatical, syntactic, semantic and domain information. This approach enables representation that reflects complex relations between acronyms and their definitions.... other words of the language. These new words can pose severe problems to many NLP applications because they represent the unknown words for them: applications based on machine learning techniques have not encountered them in training corpora, while those based on lexical resources do not have them ...

Production of morphological dictionaries of multi-word units using a multipurpose tool
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 ...electronic dictionary, Serbian, morphology, inflection, multi-word units, noun phrases, query expansion... and operates on the .NET platform.

Available technological procedures for capturing CO2 in the industrial and power generation sectors
Climate change is a major environmental issue caused by anthropogenic emissions of greenhouse gases. Capturing CO2 and storing it in suitable geological formations is one of the main technological solutions that can provide mitigation of CO2 emission into the atmosphere. Capturing CO2 represents the first phase in process of carbon capture and storage, and includes the application of various technologies for the separation of CO2 produced in the energy and industrial sectors.
