  • Geotechnical zoning of the terrain along the first section of E-80 highway in Serbia – SEETO route 7

    Dragoslav Rakić, Zoran Berisavljević, Irena Basarić, Snežana Bogdanović, Jovana Janković (2019)
    Part of E-80 highway that passes through Serbia (from the city of Nis to the administrative border Merdare) is 77 km long. The highway is divided into two sections: the first from Nis to Plocnik (39.4 km long) and the second from Plocnik to the administrative border with Kosovo. The route is designed through a typical plain and hilly terrain in which different geological units are dominant: crystalline schists, neogene sediments of foothills and quaternary sediments in the valley ...

  • Indexing of textual databases based on lexical resources: A case study for Serbian

    Ranka Stanković, Cvetana Krstev, Ivan Obradović, Olivera Kitanović (2015)
    In this paper we describe an approach to improvement of information retrieval results for large textual databases by pre-indexing documents using bag-of-words and Named Entity Recognition. The approach was applied on a database of geological projects financed by the Republic of Serbia in the last half century. Each document within this database is described by metadata, consisting of several fields such as title, domain, keywords, abstract, geographical location and the like. A bag of words was produced from these ...

  • Rock slope stability analysis under Hoek–Brown failure criterion with different flow rules

    Svetlana Melentijević, Zoran Berisavljević, Dušan Berisavljević, Claudio Olalla Marañón (2024)
    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 ...

  • Старење бунара у алувијалним срединама различитог степена оксичности

    Brankica Majkić (2013-09-27)
    Старење бунара настаје као последица процеса корозије и колмирања. Процесекорозије могуће је спречити уградњом филтерских конструкција од материјалаотпорних на корозију. Колмирање може да настане без обзира на врсту материјалаод кога се праве бунарске конструкције, а процесом може бити захваћенаприфилтарска зона па и зона саме водоносне средине. Из тог разлога тезa јеусмеренa на процесе који доводе до колмирања бунара и последицe опадањaкапацитета водозахватних објеката.

  • Litijum u mineralnim vodama Srbije – potencijalna lekovita svojstva

    Jana Štrbački (2022)
    Litijum je biološki aktivan mikroelement u ljudskom organizmu: u malim koncentracijama doprinosi pravilnom funkcionisanju pojedinih enzima, hormona i vitamina, dok se u većim, terapeutskim dozama, koristi za lečenje i prevenciju nekoliko psihijatrijskih poremećaja. Eksperimentalno je dokazano da su litijumske mineralne vode bioraspoloživi izvor ovog mikroelementa, u smislu obezbeđivanja njegovog preporučenog dnevnog unosa. Proučavanjem zakonomernosti raspodele litijuma u mineralnim vodama Srbije konstatovano je da barem 50 pojava sadrži koncentracije litijuma potrebne za unapređenje opšteg zdravstvenog stanja ljudi.

    Ispitivanja stena kao radne sredine, odnosno materijala sa kojim se gradi, na kome se gradi i u kome se gradi, svojom složenošću zahteva njeno svestrano izučavanje po velikom broju parametara. Zadatak Mehanike stena je da što bolje upozna ponašanje stenske mase i njenu otpornost na dejstvo pritiska, zatezanja i smicanja, kao i dinamičkih svojstava. Poznavanje navedenih parametara i njihova korelacija omogućavaju pouzdaniji izbor parametara za projektovanje danas sve zahtevnijih uslova kako podzemne, tako i površinske eksploatacije.

  • Back-arc underplating provided crustal accretion affecting topography and sedimentation in the Adria microplate

    Paolo Mancinelli, Vittorio Scisciani, Cristina Pauselli, Gérard M. Stampfli, Fabio Speranza, Ivana Vasiljević (2021)
    Supported by evidence of deep crustal sources for the observed magnetic anomalies in Central Italy and by outcropping gabbros in the Croatian archipelago, we model the observed gravity and magnetic anomalies in the Central Adriatic Sea and surroundings. We suggest that the major magnetic anomalies in the area are related to a wide underplating and propose that this volume represents the first stage of the back-arc Adria continental breakup in Early Permian times. During the Palaeotethys-Adria collision, underplating has ...

  • Frequency and Length of Syllables in Serbian

    Marija Radojičić, Biljana Lazić, Sebastijan Kaplar, Ranka Stanković, Ivan Obradović, Ján Mačutek, Lívia Leššová (2019)
    Basic analyses of several properties of syllables (the rank-frequency distribution, the distribution of length, and the relation between length and frequency) in Serbian is presented. The syllabification algorithm used combines the maximum onset principle and the sonority hierarchy. Results indicate that syllables behave similarly to words as far as mathematical models are concerned, but values of parameters in models for syllables are quite different from those for words.

Investigations on the level of syllables appear relatively rarely.9 In the situation described above, with a general syllable definition lacking, a scientist can apply language- specific rules for syllabification (e.g. using morpheme borders as one of the criteria ...

While the application of language-specific rules is not bad per se, if one wants to compare models, parameter values etc., a general approach to all languages under investigation is indispensable.
