Mine ventilation system planning using genetic algorithms
The most common problem in contemporary mining practice related to the planning and analysis of ventilation systems is the optimization of partially regulated air distribution in mine ventilation networks. This paper presents a two step optimization procedure for partly regulated air distribution in mine ventilation networks. The first step is the determination of air distribution in all branches using the well known Hardy-Cross method. In the second step the distribution and parameters of air flow regulators with minimum engaged ...coal, lignite, and peat; ventilation systems; coal mining; underground mining; ventilation; mathematical models; design; air flow; optimization; calculation methodsNikola Lilić, Ranka Stanković, Ivan Obradović.

Izdvajanje vode iz prirodnog gasa
Dejan Nedeljkov (2024)U radu je istaknuto važnost prirodnog gasa kao vitalna komponenta svetske energetike.Spada u najsigurnije,najčistije i najkorisnije fosilno gorivo. Sama pojava vode u vidu vlage u gasu je pokazatelj lošeg kvaliteta gasa. parametri koji mogu dovesti do lošeg kvaliteta prirodnog gasa kao pokazatelj je Wobbe index.U okviru istraživanja u master radu glavni problem funkcionisanja na KPG Paliću predstavlja vlaga u gasu,takođe se može zaključiti da kvalitet gasa zavisi od Wobbe indeksa odnosno, što je Wobbe veći, čistiji je gas, ili ...... separatora. !

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 ...... in Section 4. The paper ends with concluding remarks and an outline of future work in Section 5. 2.
