Clockwise vertical-axis rotation in the West Vardar zone of Serbia: Tectonic implications
The Vardar-Tethyan mega-suture between the Eurasian and Adria (Gondwana) margins comprises remnants of oceanic lithosphere of Neotethys and distal parts of the adjacent continental margins including unconformable Late Cretaceous sedimentary cover and Cenozoic igneous rocks of post-obduction age. This study provides kinematic constraints for displacements and rotations affecting the Serbian part of the West Vardar and Jadar-Kopaonik units after the closure of the Neotethyan (= Sava) Ocean. The targets of the paleomagnetic research were Late Cretaceous sediments representing an ...... 2 2 9 4 .4 5 .6 V ar ia b le U p p e r C a m p a n ia n 7 T o li ć q u ar ry 4 0 1 5 – 0 2 2 4 4 � 1 3 0 1 4 00 2 0 � 2 8 0 4 3 00 L im es to n e R ed 8 /8 3 5 9 .9 * 5 8 .0 * 2 7 1 3 .4 3 5 0 .1 4 6 .2 2 7 1 3 .4 3 2 2 /1 4 U p p e r C a m p a n ia n 8 L ip o v ic a q u ar ry ...

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 ...... or a geological event like landslide or earthquake. For evaluation standard measures were used, namely precision P = tp/(tp + fp), recall R = tp/(tp + fn), and F1-measure F = 2 · P · R/(P + R), where tp – true positive is the number of relevant documents retrieved, fp – false positive is the number ...
