Uticaj starosti i sastava komunalnog otpada na zbijanje
Bez obzira na mogućnost da se komunalni otpad koristi kao sirovina, u Srbiji je i dalje osnovni vid odlaganja na komunalne deponije. Iako je odlaganje na deponije prema hijerarhiji otpada najnepovoljnije rešenje, u odnosu na ranije formirana smetilišta i neuređene deponije, ipak se sistemski dolazi do prikupljanja podataka, što se može smatrati poboljšanjem prakse. Mehanička obrada komunalnog otpada zbijanjem predstavlja jednu od osnovnih metoda tretmana otpada. U radu će biti komentarisan uticaj sastava i starosti komunalnog otpada na parametre ...Jovana Janković Pantić, Dragoslav Rakić, Irena Basarić Ikodinović, Tina Đurić.

Late and post-collisional tectonic evolution of the Adria-Europe suture in the Vardar Zone
The Vardar Zone is a product of the Triassic-Jurassic opening of the Neotethys, Jurassic obduction, Late Cretaceous/Paleogene consumption of the oceanic crust and continental collision. During the last process, the Eastern Vardar Zone was thrust over the Central and eventually both onto the Western Vardar Zone. The present paleomagnetic and structural study provided new results from the first two zones in the Belgrade area. The younger set of data, together with published ones from the third zone, provide firm ...Emő Márton, Marinko Toljić, Vesna Cvetkov.

Parallel Stylometric Document Embeddings with Deep Learning Based Language Models in Literary Authorship Attribution
This paper explores the effectiveness of parallel stylometric document embeddings in solving the authorship attribution task by testing a novel approach on literary texts in 7 different languages, totaling in 7051 unique 10,000-token chunks from 700 PoS and lemma annotated documents. We used these documents to produce four document embedding models using Stylo R package (word-based, lemma-based, PoS-trigrams-based, and PoS-mask-based) and one document embedding model using mBERT for each of the seven languages. We created further derivations of these ...Mihailo Škorić, Ranka Stanković, Milica Ikonić Nešić, Joanna Byszuk, Maciej Eder.

Hidrogeohemijska valorizacija esencijalnih mikroelemenata mineralnih voda Srbije
Jana S. Stojković (2013-09-25)Mineralne vode još od davnina privlače pažnju ljudi i to kako u pogledu istraživanja iproučavanja, tako i u pogledu njihovog iskorišćavanja.

Knowledge and Rule-Based Diacritic Restoration in Serbian
In this paper we present a procedure for the restoration of diacritics in Serbian texts written using the degraded Latin alphabet. The procedure relies on the comprehensive lexical resources for Serbian: the morphological electronic dictionaries, the Corpus of Contemporary Serbian and local grammars. Dictionaries are used to identify possible candidates for the restoration, while the dataobtainedfromSrpKorandlocalgrammarsassistsinmakingadecisionbetween several candidates in cases of ambiguity. The evaluation results reveal that,dependingonthetext,accuracyrangesfrom95.03%to99.36%,whilethe precision (average 98.93%) is always higher than the recall (average 94.94%)....
