Development and Evaluation of Three Named Entity Recognition Systems for Serbian - The Case of Personal Names
In this paper we present a rule- and lexicon-based system for the recognition of Named Entities (NE) in Serbian news paper texts that was used to prepare a gold standard annotated with personal names. It was further used to prepare training sets for four different levels of annota tion, which were further used to train two Named Entity Recognition (NER) sys tems: Stanford and spaCy. All obtained models, together with a rule- and lexicon based system were evaluated on ...... Recognition Models of Croatian and Slovene. Slovenščina 2(1):35–57.

Mogućnost korišćenјa toplotnih pumpi sa otpadnom toplotom iz postrojenјa za prečišćavanјe otpadnih voda kao toplotnim izvorom
U narednom periodu se planira izgradnja nekoliko desetina sistema za prečišćavanje otpadnih voda u većim gradovima u Srbiji. Iskustva iz postrojenja koja su trenutno u radu, pokazuju da bi prečišćena otpadna voda, s obzirom na protok i temperaturu, mogla da predstavlja značajan izvor obnovljive energije. U radu su prikazani primeri dobre prakse korišćenja ove energije u sistemima daljinskog grejanja u zemljama Evropske unije.

Efekti potencijalnog korišćenja postrojenja za preradu otpadnih voda kao energetskih izvora u sistemima daljinskog grejanja u Srbiji
Системи даљинског грејања постоје у 57 градова и општина у Србији и доминантно користе фосилна горива. У овим урбаним срединама су изграђени, или се планира градња система за пречишћавање отпадних вода. У раду је размотрена (са еколошког и енергетског аспекта) могућност додатног, енергетског коришћења топлоте пречишћене воде у СДГ, применом топлотних пумпи. На примеру Шапца је извршено поређење постојећег СДГ са системом који би применом топлотних пумпи искористио енергетски потенцијал система за пречишћавање отпадних вода.

Pleistocene rhinoceros from Bogovina Cave: the first report of Stephanorhinus hundsheimensis Toula, 1902 (Mammalia, Rhinocerotidae) from Serbia
Finds of Pleistocene rhinoceros are rare in Serbia, and only one species (the woolly rhinoceros Coelodonta antiquitatis Blumenbach, 1799) has been reported so far. The current paper presents the dental material of an extinct so-called Hundsheim rhinoceros, Stephanorhinus hundsheimensis Toula, 1902 from Bogovina Cave (East ern Serbia). Both the morphological and metric characteristics of the teeth are consis tent with the attribution to S. hundsheimensis. Unfortunately, the rhinoceros material originated from an uncertain geological context, so there is no ......

Evaluation of the effects of wastewater heat pump integration into district heating systems by simulation
Dejan Ivezić, Marija Živković, Dimitrije Manić, Aleksandar Madžarević, Boban Pavlović, Dušan Danilović (2023)The integration of wastewater heat pumps (using purified water) in district heating systems is analyzed in this paper. The simulation procedure is proposed to analyze the impacts of stochasticity of purified water temperature and flow to heat pump integration and operation. The analysis includes calculation of the daily and seasonal coefficient of performance, as well as fossil fuel savings and CO2 emission reduction due to wastewater heat pump use.
