Analiza softvera za projektovanje ESP sistema
Aleksandar Sredojević (2024)U momentu kada pritisak na dnu bušotine nije dovoljan da savlada ukupne gubitke pritisaka od dna bušotine do separatora, proizvodnja pomoću ležišne energije nije više moguća i bušotina prestaje sa eruptivnim radom. Kako bi ponovo omogućili proizvodnju fluida iz bušotine, potrebno je primeniti neke od mehaničkih metoda eksploatacije. Najprimenljivije mehaničke metode eksploatacije su: gas lift (GL), dubinske pumpe sa klipnim šipkama (SRP), električne uronjene centrifugalne pumpe (ESP), zavojne pumpe (PCP) i hidraulične pumpe (HP).

Uslovi formiranja oticaja reke Crnice
Andjelija Glogovac (2024)Sliv reke Crnice zauzima područje centralnog dela Srbije, između opštine Paraćin na zapadu, Sisevačkog basena na istoku, sliva Ravanice na severu i Jovaničke reke na jugu.Režimski parametri sliva reke,površine od 289 km2 kontrolišu se na hidrološkoj stanici Paraćin, dok su sa ciljem analize režima i uticaja padavina na formiranje oticaja preuzeti podaci o padavinama sa meteorološke stanice Ćuprija.Na razmatranom području dominantnu ulogu ima karsni tip izdani, koga karakteriše nestabilan režim u u pogledu oscilacija izdašnosti i nivoa podzemnih voda ...... strmim, skoro vertikalnim otsecima. Na severu se strmo završava na levoj obali Grze, gde je Grza prosekla Jako spušteni krečnjački kamalj Ilinica, (Marković, 1954).

Using Lexical Resources for Irony and Sarcasm Classification
The paper presents a language dependent model for classification of statements into ironic and non-ironic. The model uses various language resources: morphological dictionaries, sentiment lexicon, lexicon of markers and a WordNet based ontology. This approach uses various features: antonymous pairs obtained using the reasoning rules over the Serbian WordNet ontology (R), antonymous pairs in which one member has positive sentiment polarity (PPR), polarity of positive sentiment words (PSP), ordered sequence of sentiment tags (OSA), Part-of-Speech tags of words (POS) ......
