Geološko-geofizički model dela Timočkog magmatskog kompleksa
Snežana M. Ignjatović (2014-06-30)Timočki magmatski kompleks (TMK) u geotektonskom smislu pripada KarpatoBalkanidimaistočne Srbije, koji su deo Tekijsko-Dakijske jedinice. TMK je nastaotokom kontinuirane vulkanske aktivnosti, koja je trajala oko deset miliona godina iodvijala se generalno u tri faze (Zimmerman et al., 2008, Kolb et al., 2013, Banješević,2006). Pomeranje vulkanskog fronta je išlo od istoka ka zapadu (von Quadt et al., 2002,2003, 2007). Ovaj kompleks pripada tetijskom evroazijskom metalogenetskom pojasu usvetu poznat po ležištima bakra i zlata (Janković, 1990).U doktorskoj disertaciji su prikazani rezultati ...Timočki magmatski kompleks, aeromagnetska istraživanja, gravimetrijskaistraživanja, 2D geološko-geofizički model, Valja Strž, magmatsko telo... jy ca cBrrM rrpr,rJro3r4Ma upe4ao/ra caM y erreKrpoHcrorvr $oprr,rary [oro.4HoM 3a rpaj no apxr.rBr,rp ame.

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.

On the compatibility of lexical resources for NooJ
Lexical resources for many languages are provided for the NooJ linguistic development environment. Meta-data descriptions of morphosyntactic and semantic properties of these languages and their resources are a mandatory part of each language module. In this paper we analyze how well the meta-data actually describe resources for a chosen subset of languages and to what extent are they compatible across languages to support multilingual processing. We show that there is place for improvement in both directions....

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%).... extension in the hierarchy tree ( ”Y”), extension only by subclass relations (”L”), etc. In every step, automatically derived concepts in the category description can be edited. For example, the music category can be described with the single concept Musical artY , where Y means full expansion to lower ...
