An Italian-Serbian Sentence Aligned Parallel Literary Corpus
This article presents the construction and relevance of an Italian-Serbian sentence-aligned parallel corpus, delving into the aligned sentences in order to facilitate effective translation between the two languages. The parallel corpus serves as a valuable resource for language experts, researchers, and language enthusiasts, fostering a deeper understanding of linguistic nuances and cultural expressions. By bridging the gap between Serbian and Italian, this corpus opens new avenues for cross-cultural communication and collaboration, and ultimately contributes to the improvement of language-related ...Saša Moderc, Ranka Stanković, Aleksandra Tomašević, Mihailo Škorić.

Electronic Dictionaries - from File System to lemon Based Lexical Database
In this paper we discuss some well-known morphological descriptions used in various projects and applications (most notably MULTEXT-East and Unitex) and illustrate the encountered problems on Serbian. We have spotted four groups of problems: the lack of a value for an existing category, the lack of a category, the interdependence of values and categories lacking some description, and the lack of a support for some types of categories. At the same time, various descriptions often describe exactly the same ...... generation of dictionary candidates, with their lexical and derivation variants.

Rock slope stability analysis under Hoek–Brown failure criterion with different flow rules
The stability analysis of homogeneous rock slope following the Hoek–Brown failure criterion under the hypothesis of different flow rules is performed based on limit equilibrium and finite element methods. The applied failure criterion is the generalized Hoek–Brown that can be introduced as a shear/normal function in analysis applying different flow rules. The results are compared with those obtained by the application of equivalent shear strength parameters of the Mohr–Coulomb criterion, considering that this is still the most widely used ...Kružna klizna površ, Huk-Braunov kriterijum loma, Kriterijum popuštanja, Smičuća/normalna funkcija, Nivo napona, Verovatnoća i parametarska analizaSvetlana Melentijević, Zoran Berisavljević, Dušan Berisavljević, Claudio Olalla Marañón .

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.

Mine ventilation system planning using genetic algorithms

The different approaches in seismic stratigraphy interpretation
Dejan Radivojević (2018)U tekstu su prikazana dva osnovna pristupa u seizmostratigrafskoj interpretaciji. Prvi kao polaznu osnovu ima seizmičke sekcije, čija se interpretacija u kasnijoj fazi koreliše sa bušotinskim podacima. Drugi u prvoj fazi analizira podatke dobijene dubokim bušenjem koji se kasnije korelišu sa seizmičkim sekcijama. Prikazan je hronološki redosled i objašnjen postupak pri seizmostratigrafskoj interpretaciji oba pristupa. Ovakav način interpretacije omogućio je naftnim kompanijama detaljnije i preciznije sagledavanje geoloških odnosa, smanjenje rizika istraživanja i racionalnije projektovanje razradnih bušotina.seizmostratigrafija, istraživanje nafte i gasa, karakteristične seizmičke sekvence, seiz-mofacijalna analiza...
