Верификација етажних транспортера на угљеном систему – површински коп Дрмно
Тамара Андрејевић (2024)У савременом рударству, површински копови угља наилазе на различите проблеме које треба превазићи зарад добијања потребне количине угља. Као највећи потрошачи овог енергента јављају се термоелектране, где на основу овога можемо да закључимо колико су блиско повезани добра и континуирана производња на површинском копу и рад термоелектрана. Са циљем да се обезбеди стабилна и континуирана производња, потребно је да се направи добар одабир транспортера. У овом раду, за потребе верификације затезне чврстоће траке и снаге погона транспортера, коришћен је ......

The application of ArcGIS for assessing the potential of solar energy in urban area: The case of Vranje
In order to determine the solar energy potential for a specified location, it is crucial to consider the latitude, altitude, slope, terrain morphology, atmospheric conditions, etc. Such a complex calculation and mapping of solar energy can be done using the ArcGIS geoprocessing tool, named Area Solar Radiation (ASR). By using the ASR tool, supported with the adequate input data, it is possible to calculate the maximum solar radiation energy (irradiation) for a defined area and for a specified time ...... DEM. The analysis is designed only for local landscape scales, so it is generally acceptable to use one latitude value for the whole DEM. • Sky size - the resolution of the viewshed, sky map, and sun map rasters that are used in the radiation calculations (units: cells per side). These are ...Boban Pavlović, Milica Pešić-Georgiadis.

Classification of Terms on a Positive-Negative Feelings Polarity Scale Based on Emoticons
Mihailo Škorić (2017)The goal of this paper is to draw attention to the possibility of using emoticon-riddled text on the web in language-neutral sentiment analysis. It introduces several innovations in the existing framework of research and tests their effectiveness. It also presents a software tool especially made for that purpose, explains how it builds a database with sentimental value of terms and offers the user manual. Finally, it presents a software tool that tests the new database and gives some examples ...... docu- ment, but only the speed of its processing.

Extraction of Bilingual Terminology Using Graphs, Dictionaries and GIZA++
Branislava Šandrih, Ranka Stanković (2020)U nauci, industriji i mnogim istraživačkim oblastima, terminologija se brzo razvija. Najčešće, jezik koji je „lingua franca“ za većinu ovih oblasti je engleski. Kao posledica toga, za mnoga polja termini domena su koncipirani na engleskom, a kasnije se prevode na druge jezike. U ovom radu predstavljamo pristup za automatsko izdvajanje dvojezične terminologije za englesko-srpski jezički par koji se oslanja na usaglašeni dvojezični korpus domena, ekstraktor terminologije za ciljni jezik i alat za usklađivanje delova.

Palinomorfe sa lokaliteta Gostuška reka (Stara planina)
Ivan Rutović (2024)U radu su prikazani rezultati palinološkog istraživanja permsko-trijaskih sedimenata sa lokaliteta Gostuška reka. Palinološki kompleksi su detaljno analizirani, što je omogućilo morfološku, taksonomsku i paleoekološku identifikaciju palinomorfi. Istraživanje je pokazalo prisustvo velikog broja spora i polena golosemenica, dok je polen skrivenosemenica zastupljen u manjem procentu. Na osnovu paleoekoloških analiza, zaključeno je da je tokom formiranja sedimenata na lokalitetu vladala aridna klima, sa povremenim vlažnim fazama koje su omogućavale razvoj močvarne vegetacije....

Arsenopirit iz rudnih ležišta Šumadijsko-kopaoničke oblasti: paregeneza, sastav i produkti oksidacije
Ivana N. Jelić (2023)Arsenopirit, FeAsS je čest pratilac polimetaličnih orudnjenja Šumadijsko-kopaoničke oblasti. Jedan je od sulfida koji u najvećoj meri koncentriše zlato. Nepoželjan je u rudama jer njegovom oksidacijom na jalovištima može doći do oslobađanja arsena koji spada u elemente toksične za životnu sredinu. U okviru ovog doktorata sistematski su ispitivani arsenopiriti iz različitih stadijuma i tipova orudnjenja rudnih ležišta i mineralizacija Šumadijsko-kopaoničke oblasti (Rudnik, Sastavci, Trepča, Gokčanica – Drenjak i Rujak, Golijska reka i Jurija). Uzorci arsenopirita ispitivani su polarizacionom mikroskopijom ...... presence of native gold in arsenopyrite was determined only in the sulfide occurrences of Drenjak. Gold occurs mainly in the form of grains up to 20 um in size, both in arsenopyrite and in scorodite.
