Geostatički proračuni sanacije klizišta šipovima
U ovom radu su, polazeći od rezultata geotehničkih istraživanja, prikazani geostatički proračuni sanacije klizišta vertikalnim šipovima. Metodologija proračuna je složena, jer podrazumeva interakciju klizišta i stabilizirajućih šipova. Stoga se simultano analiziraju stabilnost klizišta i stabilnost šipova. Prilikom određivanja bočne otpornosti tla oko šipova koristi se metoda Brinč Hansena koja uzima u obzir trodimenzionalne uslove u tlu i može da se primeni u složenim geološkim uslovima koji su česti u Srbiji. Analize stabilnosti klizišta vrše se odgovarajućim metodama granične ravnoteže. ...sanacija klizišta, interakcija klizišta i šipa, bočna otpornost šipova, stabilnost klizišta i šipova... ov – vefftikalni napon na dubini 2 c — kohezija К K. - koeficijenti bočnog pritiska tla Dijagrami za određivanje kocficijenta K, i K. dati su na Slikama 2 i 3.

Improving Document Retrieval in Large Domain Specific Textual Databases Using Lexical Resources
Large collections of textual documents represent an example of big data that requires the solution of three basic problems: the representation of documents, the representation of information needs and the matching of the two representations. This paper outlines the introduction of document indexing as a possible solution to document representation. Documents within a large textual database developed for geological projects in the Republic of Serbia for many years were indexed using methods developed within digital humanities: bag-of-words and named ...... idf1k = log((N + 1)/dfk)), (c) nidfk = idfk/ log(N), (d) idf okapi = log((N − dfk + 0.5)/(dfk + 0.5)); 6. Calculating the document vector combined measure: (a) tf idf = tf · idf , and vector intensity int tf idf , (b) ltf = 1 + log(tf) and vector intensity int ltf , (c) tfc = tf idf/int tf idf , (d) ...

Interactions of Copper(II) Complexes of some Schiff base ligands with calf thymus DNA and bovine serum albumin
Joni prelaznih metala u kombinaciji sa različitim ligandima nude veliki broj mogućnosti za ispitivanje potencijalnih bioaktivnosti. Među jonima prelaznih metala, bakar je poznat kao endogeni metal za ljude, sa karakterističnim biološkim redoks aktivnostima i relativno jakim afinitetom za nukleobaze. Kompleksi bakra ispoljavaju svoju antitumornu aktivnost na nekoliko različitih načina, generišu veliku količinu ROS, što uzrokuje oksidativno oštećenje mitohondrija i biomakromolekula. Nađeno je da kompleksi bakra(II) imaju umeren do dobar afinitet vezivanja sa DNK, uglavnom putem interkalacije.Angelina Petrović, Aleksandar Mijatović, Rada Baošić, Jovana Bogojeski.

Using English Baits to Catch Serbian Multi-Word Terminology
In this paper we present the first results in bilingual terminology extraction. The hypothesis of our approach is that if for a source language domain terminology exists as well as a domain aligned corpus for a source and a target language, then it is possible to extract the terminology for a target language. Our approach relies on several resources and tools: aligned domain texts, domain terminology for a source language, a terminology extractor for a target language, and a ...aligned texts, word alignment, terminology extraction, electronic dictionaries, morphological inflection... bl io te ka na uč ni bi bl io te ka re se ar ch li br ar y 1, 3, 5, 6 ye s kn ji šk om u m ol jc u kn ji šk im ol ja c kn ji šk im ol ja c kn ji žn ic rv bo ok w or m 1, 3, 5, 6 ye s su ra zr eš av an je vi še zn ač no st i ra zr eš av an je vi še zn ač ...

Numerical modeling of Selanac debris flow propagation using SPH code
The Selanac debris flow is a very huge event triggered after extreme rainfall caused by Cyclone Tamara activity in the Republic of Serbia in May 2014. The Selanac case study was already modelling in different programs using Voellmy rheology assumptions like RAMMS software.

Development of Open Educational Resources (OER) for Natural Language Processing
In this paper we present the development of an online course at the edX BAEKTEL platform named “Lexical Recognition in the Natural Language Processing (NLP)”. It is based on the course of the same name for PhD studies at the University of Belgrade, Faculty of Philology. There are not many courses in Computational Linguistics (CL) on OER platforms, and there is none in Serbian either for CL or NLP. We have developed this course in order to improve this ...... language.

Upper Miocene depositional environments of the Kikinda-Mokrin High (Serbia)
Saša Ivanišević, Dejan Radivojević (2018)Exploration for oil and gas in mature areas, such as the Pannonian Basin, can benefit from reexamination of old data using more advanced modern workflows that focus on the temporal and spatial aspects of sediment deposition. Specifically, we apply a new environment of deposition model that interprets the Upper Miocene- Pliocene sediments as being deposited in a rapidly filling basin characterized by quick shelf edge progradation from the northwest toward the southeast. Reconstruction of this shelf edge trajectory reveals ...Saša Ivanišević, Dejan Radivojević.
