Multi-Criteria Fuzzy-Stochastic Diffusion Model of Groundwater Control System Selection
When considering data and parameters in hydrogeology, there are often questions of uncertainty, vagueness, and imprecision in terms of the quantity of spatial distribution. To overcome such problems, certain data may be subjectively expressed in the form of expert judgment, whereby a heuristic approach and the use of fuzzy logic are required. In this way, decision-making criteria relating to an optimal groundwater control system do not always have a numerical value. Groundwater control scenarios (alternatives) are identified through hydrodynamic ...expert judgment, linguistic variables, fuzzy dynamic TOPSIS, hydrogeology, groundwater control system, open-cast mine, geometric Brownian motionDušan Polomčić, Zoran Gligorić, Dragoljub Bajić, Miloš Gligorić, Milanka Negovanović.

Primena modela transporta idealne čestice na primeru razvoja Površinskog kopa Jakovačka Kumša
Hidrodinamičkim proračunima transporta „idealne“ čestice prikazan je uticaj eksploatacije peskova sa površinskog kopa „Jakovačka Kumša“ na beogradsko izvorište podzemnih voda. Potencijalnu opasnost od zagađenja podzemnih voda izvorišta za vodosnabdevanje čini skup različitih procesa koji se odvijaju na površinskom kopu. U radu je prikazano poređenje dva modela transporta idealne čestice. Prvi model se odnosi na analizu putanje i vremena putovanja idealne čestice od površinskog kopa do izvorišta za stanje pre otvaranja kopa, dok se drugi model odnosi na stanje kada ...upravljnje podzemnim vodama, zaštita podzemnih voda, hidrodinamički model, metoda praćenja „idealne“ čestice, modflow, modpathDušan Polomčić, Dragoljub Bajić, Vesna Ristić Vakanjac, Marina Čokorilo Ilić.

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.

Energetska tranzicija u domaćinstvima: analiza usaglašenosti Srbije sa paketom „Čista energija za sve Evropljane“ / Energy Transition in Households: Analysis of Serbia’s Compliance with the „Clean Energy for All Europeans“ Package
Zahvaljujući svojoj složenosti i heterogenosti, sektor domaćinstva predstavlja neizostavnu tačku u politikama energetske tranzicije. U Evropskoj uniji, potrošnja energije u domaćinstvima čini oko 26% finalne potrošnje energije, dok u Srbiji ovaj sektor ima najveći udeo u finalnoj potrošnji, što čini oko trećinu finalne potrošnje. Primenom mera energetske efikasnosti moguće je ostvariti značajne energetske uštede, što zajedno sa smanjenjem i supstitucijom upotrebe fosilnih goriva vodi manjem doprinosu klimatskim promenama i značajnom smanjenju zagađenja vazduha.

Available technological procedures for capturing CO2 in the industrial and power generation sectors
Climate change is a major environmental issue caused by anthropogenic emissions of greenhouse gases. Capturing CO2 and storing it in suitable geological formations is one of the main technological solutions that can provide mitigation of CO2 emission into the atmosphere. Capturing CO2 represents the first phase in process of carbon capture and storage, and includes the application of various technologies for the separation of CO2 produced in the energy and industrial sectors. There are four main systems for capturing ......

Selection of Artificial Lift Methods: A Brief Review and New Model Based on Fuzzy Logic
Miroslav Crnogorac, Miloš Tanasijević, Dušan Danilović, Vesna Karović Maričić, Branko Leković (2020)Artificial lift methods have applications in oil wells where oil production is no longer possible due to natural reservoir energy, so this necessary energy is added by introducing lift methods. In order to achieve optimum production, the selection of an artificial lift method is very important. This paper uses fuzzy logic as a mathematical and conceptual model for selection of the optimal artificial lift method. The outcome or IF-THEN rules, as the central part of the model, is based ......
