Speleo‐morphology and tectonic processes – What can be seen in slowly deforming regions?
Ana Mladenović, Jelena Ćalić (2022)There are a lot of methods used to determine tectonic process active in a region, and they vary depending on the purpose of the research. However, a number of them cannot be used in slowly deforming regions, because the effects of active tectonic process on the rocks in such regions could be negligible. This is especially true for the recently active tectonics in such regions, since most of the recently active tectonic structures never reach the surface. Because of ...Ana Mladenović, Jelena Ćalić.

Indexing of textual databases based on lexical resources: A case study for Serbian
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 ...Ranka Stanković, Cvetana Krstev, Ivan Obradović, Olivera Kitanović.

Life Cycle Assessment of Individual Wood Biomass Heating Systems in Households
The use of solid fuels (wood biomass and coal) for heating of households continues to be common practice within European countries. Solid fuel combustion in households contributes more than 46% to total emissions of fine particulate matter. In this study, a life-cycle assessment (LCA) of firewood-based and pellet-based heating systems is performed. These two systems represent two different types of individual wood biomass heating systems. In the case of the firewood-based heating systems, it is analyzed a typical stove ...Boban Pavlović, Dejan Ivezić, Marija Živković.

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 ...Branislava Šandrih, Cvetana Krstev, Ranka Stanković.

Influence of geological substrate on runoff formation, a case study: small river catchments in southeastern Serbia of similar size and with comparable pluviographic regimes
Vesna Ristić Vakanjac, Veljko Marinović, Nikola Milovanović, Marina Čokorilo Ilić, Boris Vakanjac, Jugoslav Nikolić, Saša Bakrač (2022)We are witnessing climate change that is happening both, globally and, at the regionally - or local level. As a result of expected climate change in Southeast Europe, in the first place are the distributions of precipitation within the year (frequent extreme events are present) and then the increase in temperature, which already has a significant impact on evapotranspiration and runoff formed in a particular catchment area. In addition to climatic factors, the geological structure, i.e. the hydrogeological characteristics ...Vesna Ristić Vakanjac, Veljko Marinović, Nikola Milovanović, Marina Čokorilo Ilić, Boris Vakanjac, Jugoslav Nikolić, Saša Bakrač.

Adsorption and Polymerization of Aniline on Cu(II)-Montmorillonite: Vibrational Spectroscopy and ab Initio Calculation
Batch adsorption experiments in the presence of oxygen were performed to study the interlayer reactions of aniline on Cu(II)-montmorillonite in aqueous solutions. At concentrations below a critical value of CC ) 2.6 mmol dm-3 only a colored Cu(II)-aniline complex is formed, characterized by a stability constant of log(Kassoc/dm3 mol-1) ) 1.5. At concentrations beyond Cc aniline polymerizes yielding a dark brown product, which is identified by two vibrational spectroscopy techniques, attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy and ...M.

Digitalizacija u rudarstvu: Kreiranje sistema za efikasno poslovno izveštavanje
Proces donošenja odluka u oblasti rudarstva i geologije uslovljen je blagovremenim posedovanjem kvalitetnih podataka i informacija. Kompleksnost rudarskih procesa nalaže prikupljanje podataka na dnevnom odnosno na smenskom nivou. Podaci kao takvi bez analitičkog pristupa nisu dovoljni. Kako bi pristup podacima bio brz i efikasan neophodno je posedovanje adekvatnog digitalnog rešenja uz adekvatne centralizovane baze podataka.

Tehnike mekog računarstva u hidrogeologiji
Meko računarstvo predstavlja skup inteligentnih metoda koje se, za razliku od klasičnog računarstva, zasnivaju na približnom izračunavanju i zaključivanju. Ove metode imitiraju biološke procese kao što su neuroni u mozgu, evolucijski procesi i ljudska sposobnost zaključivanja, što omogućava efikasno rešavanje problema koje je teško rešiti tradicionalnim matematičkim i računarskim metodama. Tehnike mekog računarstva, poput veštačkih neuronskih mreža (ANN), fazi logike i adaptivnih neuro-fazi sistema zaključivanja (ANFIS), su široko korištene i pokazale su se pouzdanim i jednostavnim za simulaciju složenih ...Ivan Drakulić, Dušan Polomčić, Jelena Ratković, Dragoljub Bajić.

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