Underground loading-haulage equipment selection with application of topsis method with different weighting methods of criteria
The choice of adequate mining machines is one of the most complex problems in the underground exploitation of mineral raw materials. The weight of such a decision is reflected in the high prices of these machines and the occurrence of even greater costs during their use if their choice was wrongly conceived. There are numerous examples from practice in which such decisions were made solely on the basis of comparing the prices of machines, without considering any of the ...utovarno-transportna mehanizacija, izbor, TOPSIS, entropija, standardna devijacija, težina kriterijumaVladimir Krivošić, Luka Crnogorac, Rade Tokalić.

Geotehnički uslovi rekonstrukcije Zavičajnog muzeja u Jagodini
Milan Tokanović (2024)U radu su prikazana geotehnička istraživanja za potrebe rekonstrukcije Zavičajnog muzeja Jagodina.Zavičajni muzej u ulici Kneginje Milice br.82 u Jagodini, ima ozbiljna oštećenja pojedinih delova konstrukcije koja su nastala na objektu tokom više od 80 godina eksploatacije.Kako bi se trajno rešio problem dinamičke stabilnosti i statičke održivosti konstruktivnog sistema objekta,neophodno je bilo definisanje geotehničkih uslova u zoni interakcije prirodne sredine i konstrukcije predmetnog objekta.Izvedena su terenska i laboratorijska ispitivanja na osnovu kojih su dobijene geotehničke podloge.

Machine learning based landslide assessment of the Belgrade metropolitan area: Pixel resolution effects and a cross-scaling concept
Improvements of Machine Learning-based landslide prediction models can be made by optimizing scale, customizing training samples to provide sets with the best examples, feature selection, etc. Herein, a novel approach, named Cross-Scaling, is proposed that includes the mixing of training and testing set resolutions. Hypothetically, training on a coarser resolution dataset and testing the model on a finer resolution should help the algorithm to better generalize ambiguous examples of landslide classes and yield fewer over/underestimations in the model.

Analiza softvera za projektovanje ESP sistema
Aleksandar Sredojević (2024)U momentu kada pritisak na dnu bušotine nije dovoljan da savlada ukupne gubitke pritisaka od dna bušotine do separatora, proizvodnja pomoću ležišne energije nije više moguća i bušotina prestaje sa eruptivnim radom. Kako bi ponovo omogućili proizvodnju fluida iz bušotine, potrebno je primeniti neke od mehaničkih metoda eksploatacije. Najprimenljivije mehaničke metode eksploatacije su: gas lift (GL), dubinske pumpe sa klipnim šipkama (SRP), električne uronjene centrifugalne pumpe (ESP), zavojne pumpe (PCP) i hidraulične pumpe (HP).

A Description of Morphological Features of Serbian: a Revision using Feature System Declaration
In this paper we discuss some well-known morphological descriptions used in various projects and applications (most notably MULTEXT-East and Unitex) and illustrate the encountered problems on Serbian. We have spotted four groups of problems: the lack of a value for an existing category, the lack of a category, the interdependence of values and categories lacking some description, and the lack of a support for some types of categories. At the same time, various descriptions often describe exactly the same ...... es XXII, Amsterdam-Philadelphie : Benjamins, pp. 341-367.

Kvartarni klastiti iz bušotine kod Aranđelovca (rasadnik Mladost)
Miroslav Radeta (2024)U ovom radu analizirani su kvartarni klastiti iz bušotine kod Aranđelovca IB 18-3, sa ciljem boljeg razumevanja njihovih sedimentoloških i litoloških karakteristika. Kvartarni sedimenti su prilično homogenog/uniformisanog sastava i čine ih finozrni klastiti (dominantno alevroliti) sa određenim procentom peskovite i glinovite frakcije. Oni su iskartirani u samoj povlati i debljina im je 27 m. U podini su gornjokredne karbonatne stene (krečnjaci, laporci, rekristalisali/mermerisani karbonati) i miocenski sediment predstavljeni raznovrsnim varijetetima klastično karbonatnih stena.

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 ...... ć, M.; Ivezić, D.; Jovančić, P.; Ćatić, D.; Zlatanovic, D.

Fuzzy expert analysis of the severity of mining machinery failure
Mining machinery failure is almost an everyday occurrence. Usually the failures bare certain consequences, which require additional financial costs to repair and restore the system to its operational state. The consequences are viewed through negative and damaging effects a failure has on the machine, health and safety of the employees, work environment, and on the environment. The removal of the consequences of the failure requires additional financial investment, which has a negative impact on the company’s business. In order ...Dejan V.

Utilizing sewage wastewater heat in district heating systems in Serbia: effects on sustainability
Marija Živković, Dejan Ivezić (2021)Transformation of the heating sector is recognized as being essential for ensuring reliable and afordable energy services provided with reduced consumption of energy sources and diminished impact on the environment and less import dependency. The possibility of utilizing energy sources that otherwise would be wasted needs to be considered and treated as a big advantage of district heating systems. Despite many advantages, sewage wastewater heat is still a mostly unused resource at the global level and a totally unused ...рекуперација топлоте из отпадних вода, систем даљинског грејања, топлотне пумпе, енергетске уштеде, емисија угљендиоксида, енергетска безбедност, Србија...
