Control of substructure construction of railways in the Republic of Serbia
Контрола збијености природног тла (у ископу) или збијеног у насипу при изградњи саобраћајница представља један од основних облика контроле квалитета доњег строја. Код изградње брзих саобраћајница (аутопутеви и брза железница) приоритет је постизање високог нивоа контроле извршених радова. У циљу онемогућавања диференцијалног слегања (при изградњи насипа), или промене запремине услед допунског збијања материјала, које неминовно доводе до деформација, потребно је извршити оптимално збијање материјала. У оквиру овог рада приказује се техничка регулатива која регулише контролу збијености при изградњи железничке ...... polluted water (or other liquids), and according to the pollution protection solution.

Утицај промене нивоа подземне воде за услове плитког фундирања у крупнозрном тлу
Милана Мичета (2024)Подземне воде представљају изузетно важан природни ресурс, као и важну компоненту система, којим је представљено тло. У складу са тим, приликом пројектовања плитких темеља на крупнозрном тлу, односно приликом анализе граничне носивости и слегања, треба узети у обзир и утицај воде. Верује се да ниво подземне воде значајно смањује носивост тла, док се слегања значајно повећавају. Terzaghi (1943) је први сугерисао да се потапањем масе тла, његова носивост смањује за половину, док се слегање удвостручује.

Machine Learning and Deep Neural Network-Based Lemmatization and Morphosyntactic Tagging for Serbian
The training of new tagger models for Serbian is primarily motivated by the enhancement of the existing tagset with the grammatical category of a gender. The harmonization of resources that were manually annotated within different projects over a long period of time was an important task, enabled by the development of tools that support partial automation. The supporting tools take into account different taggers and tagsets. This paper focuses on TreeTagger and spaCy taggers, and the annotation schema alignment ......

Ograničenja primene optimizacionih algoritama u slučaju kopova
Proces optimizacije površinskih kopova, kao sastavni deo strateškog planiranja, veoma je važan sa stanovišta ostvarivanja maksimalnih efekata proizvodnje. To je složen zadatak koji vrlo često podleže vrlo strogim geometrijskim i drugim praktičnim rudarskim ograničenjima. Ova ograničenja u posebno su izražena na površinskim kopovima uglja, te u značajnoj meri mogu povećati stepen neizvesnosti rudarskog projekta, odnosno izazvati neželjena dejstva u pogledu profitabilnosti poslovanja.

Frequency and Length of Syllables in Serbian
Marija Radojičić, Biljana Lazić, Sebastijan Kaplar, Ranka Stanković, Ivan Obradović, Ján Mačutek, Lívia Leššová (2019)Basic analyses of several properties of syllables (the rank-frequency distribution, the distribution of length, and the relation between length and frequency) in Serbian is presented. The syllabification algorithm used combines the maximum onset principle and the sonority hierarchy.

Rock slope stability analysis under Hoek–Brown failure criterion with different flow rules
The stability analysis of homogeneous rock slope following the Hoek–Brown failure criterion under the hypothesis of different flow rules is performed based on limit equilibrium and finite element methods. The applied failure criterion is the generalized Hoek–Brown that can be introduced as a shear/normal function in analysis applying different flow rules. The results are compared with those obtained by the application of equivalent shear strength parameters of the Mohr–Coulomb criterion, considering that this is still the most widely used ...Kružna klizna površ, Huk-Braunov kriterijum loma, Kriterijum popuštanja, Smičuća/normalna funkcija, Nivo napona, Verovatnoća i parametarska analizaSvetlana Melentijević, Zoran Berisavljević, Dušan Berisavljević, Claudio Olalla Marañón .

Palaeoflora of Kamenica (Pranjani Basin, western Serbia)
Palaeofloras of the Paleogene in Serbia are relatively rare, especially in comparison with floras from Neogene sediments. Most Paleogene phytoas sociations from the territory of Serbia existed in a dry and warm climate. The youngest Paleogene phytoassociation originates from the Pranjani Basin (Western Serbia), locality Kamenica. The age of this palaeoflora is determined as Late Oligocene. This fossil plant assemblage is different from other Paleo gene phytoassociations.The palaeoflora from Kamenica is characterized with leaf imprints larger than in other ...... banks of the river and the margins of the lake basin. a significant number of samples in this locality belongs to pines: Pinus hepios (Plate 1 Fig. 5), Pinus palaeopentaphylla (Plate 1, Figs. 1, 3, 4, 7). vegetation elements of temperate climate are very rare, and represented only by a few imprints of ...

On the compatibility of lexical resources for NooJ
Lexical resources for many languages are provided for the NooJ linguistic development environment. Meta-data descriptions of morphosyntactic and semantic properties of these languages and their resources are a mandatory part of each language module. In this paper we analyze how well the meta-data actually describe resources for a chosen subset of languages and to what extent are they compatible across languages to support multilingual processing.

Rule-based Automatic Multi-word Term Extraction and Lemmatization
In this paper we present a rule-based method for multi-word term extraction that relies on extensive lexical resources in the form of electronic dictionaries and finite-state transducers for modelling various syntactic structures of multi-word terms.

Coupling of artificial intelligence methods in the development of hybrid intelligent systems
In this paper we present an approach which couples various artificial intelligence (AI) methods in the solution of complex problems that cannot adequately be solved by a single AI method. We argue that the resulting, hybrid intelligent systems (HIS) can be successfully implemented with the use of available AI software libraries. Different coupling methods are analyzed and a classification of hybrid systems based on the chosen method is given. Two case studies of hybrid systems used in mining engineering ...hibridni inteligentni sistemi, spregnuti sistemi, metode veštačke inteligencije, rudarske primene veštačke inteligencije...

Heavy metals in lignite and soil of Kostolac-Kovin coal basin, eastern Serbia - comparative analysis with selected cities in Serbia, region, Europe and world
Bogoljub Vučković, Bojan Dimitrijević (2023)The Kostolac-Kovin coal basin with an area of 320 km2, with 5 separate layers of coal and with a total of about 5.7 Bt of geological resources and reserves represents an exceptional potential for coal production in Serbia. The coal resources listed in this way are not fully exploitable, but they represent potential for consideration.

The different approaches in seismic stratigraphy interpretation
Dejan Radivojević (2018)U tekstu su prikazana dva osnovna pristupa u seizmostratigrafskoj interpretaciji. Prvi kao polaznu osnovu ima seizmičke sekcije, čija se interpretacija u kasnijoj fazi koreliše sa bušotinskim podacima. Drugi u prvoj fazi analizira podatke dobijene dubokim bušenjem koji se kasnije korelišu sa seizmičkim sekcijama. Prikazan je hronološki redosled i objašnjen postupak pri seizmostratigrafskoj interpretaciji oba pristupa. Ovakav način interpretacije omogućio je naftnim kompanijama detaljnije i preciznije sagledavanje geoloških odnosa, smanjenje rizika istraživanja i racionalnije projektovanje razradnih bušotina.seizmostratigrafija, istraživanje nafte i gasa, karakteristične seizmičke sekvence, seiz-mofacijalna analiza... razradnih bušotina. 5.
