Mitigating hydrate formation in onshore gas wells: A case study on optimization techniques and prevention
Gas wells, particularly those situated onshore, play a vital role in the global energy sector by supplying a significant portion of natural gas. However, operational challenges, notably gas hydrate formation, pose substantial issues, leading to complications such as flowline blockages and unexpected well shutdowns. Gas hydrates, crystalline structures resembling ice, ...Gas Well, Gas Hydrate Formation, Well Modeling, Well Performance Optimization, Choke Position Adjustments, Methanol InjectionMilica Ješić, Bojan Martinović, Stefan Stančić, Miroslav Crnogorac, Dušan Danilović.

Parallel Stylometric Document Embeddings with Deep Learning Based Language Models in Literary Authorship Attribution
This paper explores the effectiveness of parallel stylometric document embeddings in solving the authorship attribution task by testing a novel approach on literary texts in 7 different languages, totaling in 7051 unique 10,000-token chunks from 700 PoS and lemma annotated documents. We used these documents to produce four document embedding models using Stylo R package (word-based, lemma-based, PoS-trigrams-based, and PoS-mask-based) and one document embedding model using mBERT for each of the seven languages. We created further derivations of these ...Mihailo Škorić, Ranka Stanković, Milica Ikonić Nešić, Joanna Byszuk, Maciej Eder.

Анализа рада дисконтинуалног система на основу симулације утовара и транспорта целог површинског копа
Милош Јовановић (2024)У овом раду анализира се рад дисконтинуалног система утовара и транспорта на површинским коповима користећи софтверски пакет Haulsim. Циљ истраживања је побољшање ефикасности процеса транспорта и оптимизација коришћења ресурса. Симулација је спроведена за различите сценарије утовара и транспорта, укључујући варијације у броју возила, њиховој брзини, капацитету, као и рутама транспорта. Добијени резултати су показали значајне могућности за унапређење постојећих процедура и смањење трошкова.

Fault type assessment based on vertical gravity gradient anomalies – advantages and limitations
The type of dip-slip faults can be assessed based on the analysis of vertical gravity gradients. Theoretically, just a simple comparation of the gradient extreme values can give us an answer whether the fault is normal or reverse (thrust). Practical application of this method is far more complicated and the results depend on a number of parameters, such as a complexity of geological setting, the quality of gravity data, dip angle and displacement of the fault, density contrast, etc. ...... l Sciences, 50(1): 127-139.

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 ...... ‘(gold OR Au) AND (Bor OR Bor district)’. For evaluation standard measures were used, namely Precision P = tp/(tp+ fp), Recall R = tp/(tp+ fn), and F- measure F = 2 ·P ·R/(P +R), where tp – true positive is the number of relevant documents retrieved, fp – false positive is the number of non-relevant documents ...
... negative is the number of relevant documents that were not retrieved. During the evaluation ranked responses were offered to users, and the measures P and R were calculated for sets containing the first i choices of- fered, where i ∈ [1, 120] [8].

Effectiveness Analysis of Different Bucket-wheel Excavators
Coal production in open-pit lignite mines in the Republic of Serbia is performed with continuous work systems. In addition to coal production, the same systems are used for the exploitation of large quantities of overburden. According to the reliability concept, continuous systems are in linear connection. If the failure occurs in one part of the system, that will produce a downtime of the entire system. The initial and most important factor of continuous systems is the bucket-wheel excavator.

Specifičnosti fundiranja u lesnim naslagama – objekat Poreska uprava Zemun
Anja Dević (2024)U ovom završnom radu prikazani su literaturni podaci koji se odnose na geotehničke karakteristike terena izgrađenih od lesa na primeru šireg istražnog prostora, tzv. Zemunskog lesnog platoa, kao i rezultati detaljnih geotehničkih istraživanja na lokaciji objekta Poreske uprave Zemun. U prvom delu rada prikazani su uslovi nastanka karakteristične makroporozne strukture lesa i njen uticaj na fizičko-mehaničke karakteristike i stabilnost terena izgrađenih od lesa. Na osnovu analize i interpretacije rezultata detaljnih geotehničkih istraživanja na lokaciji objekta Poreske uprave Zemun prikazane su ...... — 5 ui i f O | [14 < [| < oO ul C r d — < ~ ILI r [) o 7 o _— i [} a E – [-:] o o o a + a o o [će] e Woeo JJo NI J saaay2a o y O š r v š č š č g g e j ! y o N o Y o g P e B R B r n e ı s n ı S B 8 Š Datum: novembar 2023 ...
