Fuzzy stohastički model izbora sistema otvaranja podzemnog rudnika
Saša M. Jovanović (2016-05-16)Investiciono okruženje skopčano sa rudarskom industrijom je veoma svojstveno kada seuporedi sa okruženjima koje susrećemo u tipičnim proizvodnim industrijama. Neke odkarakterisitka rudarstva, koje su često naznačene kao jedinstvene su: visok intenzitetinvesticija, dugi predproizvodni periodi, visok rizik i neobnovljivost resursa.Investiranje u sistem otvaranja rudnika predstavlja dobar primer ireverzibilneinvesticije. Takva investicija zahteva pažljivu analizu, jer nakon njene realizacije ona sene može nadoknaditi bez značajnog gubitka vrednosti. Očigledno je da izbor sistemaotvaranja podzemnog rudnika pripada strateškom planiranju...Saša M. Jovanović.

Hypogene karst associated with igneous intrusions and its influence on the subsequent karst evolution in high mountains (Central Andes, Peru)
Carbonate rocks of Cretaceous age are wide spread in the Peruvian Andes. The studied area in the eastern part of the Cordillera Occidental, near a large igneous intrusion and a skarn deposit, exemplifies polygenetic and multi-phase karst development. Hypogene karstification is related to a hydrothermal activity associated with a magmatic event at ca. 11-9.7 Ma responsible for the emplacement of the nearby intrusion and related alteration of the carbonate rocks. It has resulted in deep-rooted, laterally isolated stair-case-rising shaft ...Alexander B. Klimchouk, Saša Milanović, Cristian Bittencourt.

Two approaches to compilation of bilingual multi-word terminology lists from lexical resources
In this paper, we present two approaches and the implemented system for bilingual terminology extraction that rely on an aligned bilingual domain corpus, a terminology extractor for a target language, and a tool for chunk alignment. The two approaches differ in the way terminology for the source language is obtained: the first relies on an existing domain terminology lexicon, while the second one uses a term extraction tool. For both approaches, four experiments were performed with two parameters being ...... input corpus (for text). • Additional filtering of results obtained by GIZA++: 12 B. Šandrih, C. Krstev and R.

Numerical modeling of Selanac debris flow propagation using SPH code
The Selanac debris flow is a very huge event triggered after extreme rainfall caused by Cyclone Tamara activity in the Republic of Serbia in May 2014. The Selanac case study was already modelling in different programs using Voellmy rheology assumptions like RAMMS software. In this paper research are focusing particularly on the process of debris flowing from initiation zone to main deposition area using Geoflow SPH two-phase model considering frictional rheology law. Main rheological parameters are back-calculated using also ...Jelka Krušić, Biljana Abolmasov, Miloš Marjanović, Manuel Pastor, Saeid M. Tayyebi .
