Different aspects of soft computing methods application for blasting in mining
Mining is a global industry that is of great importance for every product which is used by human. For mining, process efficiency, reducing production downtime, increasing profitability are all very important. Soft computing tehnologies (SC) are helping in the process of transforming the mining industry into a safer and more environmental friendly industry, but keeping in mind the financial aspect as well. In this paper some of fields of blasting activities in which the SC methods have been applicated, ...Katarina Urošević, Jelena Zakonović, Radmila Gaćina.

Determining the Groundwater Balance and Radius of Influence Using Hydrodynamic Modeling: the Case Study of the Groundwater Source “Šumice” (Kikinda, Serbia)
A groundwater flow model was developed to simulate groundwater extraction from the public water supply source of the City of Kikinda. The hydrodynamic model includes the municipal groundwater source of Kikinda (Šumice and the Jezero Well), but also an extended area where there are groundwater sources that provide water supply to three factories: (MSK, TM and LŽT - Kikinda). Hydrodynamic modeling, based on the numerical method of finite differences will show the groundwater balance of the sources in the ......

Geomorfološke posledice poplava 2014. godine u karstu Dževrinske grede (istočna Srbija)
The year 2014 was the year of extremely large floods in Serbia. The territories of municipalities Kladovo and Negotin, along the Danube course in Eastern Serbia, were among the worst affected, mostly by flash floods. The karst ridge of Dževrinska Greda, a typical contact karst and stripe karst environment formed within Upper Jurassic limestones, suffered significant morphological changes in terms of heavy washout of sediments on one hand (in fluviokarstic gorges and active cave passages), and on the other ...Jelena Ćalić, Dejan Jeremić, Ana Mladenović.

Knowledge Graphs in the Era of Large Language Models: Opportunities and Challenges
Pojava velikih jezičkih modela (eng. Large Language Models ili LLMs) je značajno uticala na oblast veštačke inteligencije, naročito u oblastima obrade prirodnog jezika i generisanju teksta. Međutim, ključno ograničenje ovih modela leži u nedostatku strukturiranog znanja i sposobnosti zaključivanja, što otežava njihovu primenu u stvarnom svetu, gde se zahteva tačnost iznetih činjenica i zaključivanje na osnovu konteksta. S druge strane, grafovi znanja nude primamljivo rešenje. Oni pružaju bogat izvor strukturiranog znanja, tako što predstavljaju entitete i njihove relacije u ...grafovi znanja, veliki jezički modeli, obrada prirodnog jezika, strukturirano znanje, kvalitet podataka, objašnjiva veštačka inteligencija, bezbednost sadržaja na internetuDanka Jokić, Ranka Stanković, Jelena Jaćimović.

Social-Emo.Sr: Emotional Multi-Label Categorization of Conversational Messages from Social Networks X and Reddit
U digitalnom okruženju južnoslovenskih jezika, analiza emocija u tekstovima na društvenim mrežama postaje sve važnija za razumevanje javnog mnjenja, kreiranje personalizovanog sadržaja i analizu međusobnih interakcija korisnika. U okviru ovog rada predstavljamo detaljnu metodologiju i rezultate označavanja korpusa na srpskom jeziku prema Plutčikovom modelu kategorizacije, koji prepoznaje osam osnovnih emocionalnih kategorija, kao što su radost, tuga, bes, strah, poverenje, gađenje, iščekivanje i iznenađenje.

Rezultati ispitivanja parametara čvrstoće i dinamičkih svojstava mermera i mogućnost njihove korelacije
Ispitivanja stena kao radne sredine, odnosno materijala sa kojim se gradi, na kome se gradi i u kome se gradi, svojom složenošću zahteva njeno svestrano izučavanje po velikom broju parametara. Zadatak Mehanike stena je da što bolje upozna ponašanje stenske mase i njenu otpornost na dejstvo pritiska, zatezanja i smicanja, kao i dinamičkih svojstava. Poznavanje navedenih parametara i njihova korelacija omogućavaju pouzdaniji izbor parametara za projektovanje danas sve zahtevnijih uslova kako podzemne, tako i površinske eksploatacije.

History of the development of the hydrodynamic model of the open pit mine “Drmno”, Serbia
With the creation of a hydrodynamic model, the need for it usually ceases until some next moment when the model needs to be updated and used for the set task for the necessary project documentation or dedicated studies. It is relatively rare that almost every year the model is improved and used for forecast calculations. The paper presents the basic characteristics and development of the hydrodynamic model of the open pit mine “Drmno” for 25 years.
