Потреба за израдом биланса и оценом расположивих резерви подземних вода Републике Србије
Природне карактеристике Србије, просторна дистрибуција ресурса водe и њихових корисника, као и међусобна интеракција коришћења, заштите вода, као и заштите од вода, условиле су да се подземне воде на читавој територији морају посматрати интегрално, јединствено, комплексно и рационално. Међутим, тренутно је у Републици Србији могуће дефинисати само одлике појединих издани и/или изворишта услед непостојања довољних података за свеобухватну анализу стања ресурса. За оцену притиска на квантитет ресурса подземних вода, што је обавеза према Оквирној директиви о водама ЕУ (ОДВ) ...Зоран Стевановић, Вељко Мариновић, Бранислав Петровић.

Present Situation and Alternative Water Supply Solutions for Northern Vojvodina (Serbia)
The northern part of the Autonomous Province of Vojvodina is situated in the central and southeastern sectors of the Pannonian Basin. Drinking water supply is provided by groundwater abstraction from depths of 60 to 200 m. The quality of that water is poor, especially due to high concentrations of arsenic which most water supply systems do not remove. Current planning documents call for the construction of large regional water supply schemes on the banks of the Danube and Tisa ...Bojan Hajdin, Vesna Ristić-Vakanjac, Dušan Polomčić.

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.

Sentiment Analysis of Serbian Old Novels
In this paper we present first study of Sentiment Analysis (SA) of Serbian novels from the 1840-1920 period. The preparation of sentiment lexicon was based on three existing lexicons: NRC, AFFIN and Bing with additional extensive corrections. The first phase of dataset refinement included filtering the word that are not found in Serbian morphological dictionary and in second automatic POS tagging and lemma were manually corrected. The polarity lexicon was extracted and transformed into ontolex-lemon and published as initial ...Ranka Stanković, Miloš Košprdić, Milica Ikonić Nešić, Tijana Radović.

Specific electrical conductivity in epikarst groundwater of the eastern Suva Planina mt.
Branislav Petrović (2022)The epikarst is a part of the karst outcrop that is located within the unsaturated zone and represents a complex point of contact and mixing of unconsolidated material from the terrain surface. The correct and complete perception of epikarst, its degree of development and the presence on the limestone terrain can be achieved with a multidisciplinary approach. The study area for the applied multidisciplinary research was the Eastern part of karst massif Suva Planina Mt. One important part of ...Branislav Petrović.

Estimating hydraulic parameters for the complex hydrodynamic models
Hydrodynamic models have usually been calibrated manually, by trial-and-error, with different values of hydraulic parameters and hydraulic characteristics of boundary conditions. This method of calibration and estimation of hydraulic parameters requires an extensive knowledge and experience of experts, but whether the resulting solution includes an optimal set of parameters still remains an open question. An optimization method founded upon the Gauss-Marquardt-Levenberg algorithm, along with PEST software based on that algorithm, introduces automation of model calibration with regularization, which substantially ...Dušan Polomčić, Dragoljub Bajić, Jelena Ratković, Bojan Hajdin.

Applicability of the risk ranking methodology designed for water reservoirs to tailings storage facilities
The risks associated with operating water reservoirs and tailings storage facilities (TSFs) are different because of their different purposes, methods of construction and operation, and characteristics of the materials impounded and their flow behaviour. Regardless of the differences, these two types of structures are often put in the same category when it comes to risk assessment and the application of relevant methodologies, which may result in unrealistic outcomes. In this paper we investigate whether it is possible to apply ...Dragana Nišić, Dinko Knežević, Aleksandar Cvjetić, Neda Nišić, Vladimir Jovanović.

Effect of natural gas composition on methane number: A case of gas reservoirs in Serbia
Natural gas is considered as the most environmentally acceptable fossil fuel, thus it is an alternative to petroleum derivate, dominantly used in internal combustion engines. Physical properties of a fuel as well as behavior during combustion process are affected by its composition. This article presents analysis of effect of natural gas composition on methane number (MN), conducted for natural gas deposits in Serbia. For empirically determination of MN: California air resources board (CARB) method and Linear and Anstalt für ...Marija Živković, Milica Ivić, Dejan Ivezić, Aleksandar Madžarević.

Transformer-Based Composite Language Models for Text Evaluation and Classification
Parallel natural language processing systems were previously successfully tested on the tasks of part-of-speech tagging and authorship attribution through mini-language modeling, for which they achieved significantly better results than independent methods in the cases of seven European languages. The aim of this paper is to present the advantages of using composite language models in the processing and evaluation of texts written in arbitrary highly inflective and morphology-rich natural language, particularly Serbian. A perplexity-based dataset, the main asset for the ...Mihailo Škorić, Miloš Utvić, Ranka Stanković.

Energetska bezbednost sektora prirodnog gasa Srbije
U prve dve decenije 21. veka obezbeđivanje sigurnosti snabdevanja prirodnim gasom domaćeg tržišta bio je jedan od prioriteta razvoja energetike Srbije. Istovremeno, aspekt sigurnog snabdevanja bio je neizostavni deo slagalice stvaranja energetske bezbednosti. Izražena uvozna zavisnost je dominantna karakteristika sektora prirodnog gasa, tačnije, Republika Srbija je snažno zavisna od ruskog gasa, sa više od 80% uvezenih količina gasa, a do pre dve godine snabdevala se isključivo kroz jednu interkonekciju. U radu se razmatra aktuelna situacija u sektoru prirodnog ...... paper also presents a new methodology for determining the impact of system readiness and the number of sources and directions of supply, as well as their mutual interaction, on the security of supply, and ultimately on the energy security of the Republic of Serbia.

Smanjenje sleganja plitkih temelja primenom mikrošipova
Slobodan Ćorić, Dragoslav Rakić (2021)Mikrošipovi su šipovi malog prečnika koji se grade tako što se u tlu specijalni postupkom formira bušotina koja se zatim armira i injektira. Njihov prečnik je najčešće 150 – 300 mm, a dužina može da bude i više desetina metara. Mikrošipovi mogu da se grade u svim vrstama tla i mogu da budu vertikalni i kosi. Oni se, stoga, koriste kao zamena za konvencionalne šipove i ankere. Primena mikrošipova u fundiranju predstavlja jedan savremeni način izgradnje i sanacije temelja/objekata. ...Slobodan Ćorić, Dragoslav Rakić.
