  • Tektonska evolucija istočne periferije timočke eruptivne oblasti

    Stefan Zujić (2024)
    U radu su predstavljeni rezultati proučavanja tektonskih i litostratigrafskih karakteristika istočnog oboda Timočke eruptivne zone. Zaključci o geološkim odnosima u okviru Timočke eruptivne oblasti i susednih geotektonskih jedinica izvedeni su na osnovu podataka prikuljenih tokom terenskih istraživanja i podataka dobijenih iz publikovanih radova. Rezultati rada ukazuju da je teren koji je bio tema ovog istraživanja, u strukturno-tektonskom smislu oblikovan tokom glavnih geodinamičkih događaja u okviru Karpato-balkanskog orogenog luka. Analizom strukturnog sklopa su utvrđeni glavni deformacioni događaji koji su predsavljeni ...

  • The ‘Umka’ landslide

    Uroš Đurić, Dragana Đurić, Miloš Marjanović, Biljana Abolmasov, Ivana Vasiljević (2024)
    We present an in-depth landslide map of the ‘Umka’ landslide near Belgrade, Serbia, at a scale of 1:5000. The map delineates elements at risk, primarily buildings and road infrastructure impacted by the landslide displacements of several cm per year, introduced during frequent reactivation stages. The Main map results from a survey of over 350 buildings and more than 7 km of state and local roads. The acquisition techniques included engineering geological field mapping, building survey, and visual interpretation of ...

  • Dehydroicetexanes in sediments and crude oils: Possible markers for Cupressoideae

    Hans Peter Nytoft, Geir Kildahl-Andersen, Sofie Lindström, Frode Rise, Achim Bechtel, Danica Mitrović, Nataša Đoković, Dragana Životić, Ksenija A. Stojanović (2019)
    Two previously unidentified dehydroabietane isomers were isolated from Miocene Serbian lignite and Rhaetian (Late Triassic) coaly mudstones from South Sweden and characterized using NMRspectroscopy as cis- and trans-dehydroicetexane. Both have a 9(10?20)-abeo-abietane or icetexane skeleton, consisting of a 6-7-6 tricyclic framework with seven carbons in ring B instead of the usual six in common diterpanes of the abietane-type. Dehydroicetexanes can be detected using GC-MS-MS in m/z 270?146 chromatograms without interference from dehydroabietane or other isomers. Dehydroicetexanes are often abundant ...

  • Late and post-collisional tectonic evolution of the Adria-Europe suture in the Vardar Zone

    Emő Márton, Marinko Toljić, Vesna Cvetkov (2022)
    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 ...

  • Machine learning based landslide assessment of the Belgrade metropolitan area: Pixel resolution effects and a cross-scaling concept

    Uroš Đurić, Miloš Marjanović, Zoran Radić, Biljana Abolmasov (2019)
    Improvements of Machine Learning-based landslide prediction models can be made by optimizing scale, customizing training samples to provide sets with the best examples, feature selection, etc. Herein, a novel approach, named Cross-Scaling, is proposed that includes the mixing of training and testing set resolutions. Hypothetically, training on a coarser resolution dataset and testing the model on a finer resolution should help the algorithm to better generalize ambiguous examples of landslide classes and yield fewer over/underestimations in the model. This ...

  • Просторни положај лежишта угља Ђурђевик: геофизичко-геолошки модел

    Синиша Арсеновић (2019)
    Лежиште угља Ђурђевик представља источни део Бановићког угљеног басена и припада северној страни босанске офиолитске зоне унутрашњих Динарида у чији састав улазе стене палеозојске, мезозојске и кенозојске старости. Језерска доњомиоценска угљоносна серија изграђена је од лапоровито-глиновитих седимената са једним слојем мрког угља. Дебљина угљеног слоја креће се у интервалу од 5 до 25 m са генералним правцем пружања СЗ - ЈИ и падом према ЈЗ.

  • Named Entity Recognition for Distant Reading in ELTeC

    Akcija COST „Udaljeno čitanje za evropsku književnu istoriju“, koja je počela 2017. godine, ima među svojim glavnim ciljevima stvaranje višejezične zbirke evropskih književnih tekstova (ELTeC) otvorenog koda. U ovom radu predstavljamo rad koji je obavljen na ručnom označavanju selekcije ELTeC kolekcije za imenovane entitete, kao i na proceni postojećih alata za prepoznavanje imenovanih entiteta u pogledu njihove sposobnosti da automatski urade takve anotacije. U poslednjem paragrafu se razmatraju zajedničke tačke između ove inicijative i CLARIN-a.
