Evaluation of the effects of wastewater heat pump integration into district heating systems by simulation
Dejan Ivezić, Marija Živković, Dimitrije Manić, Aleksandar Madžarević, Boban Pavlović, Dušan Danilović (2023)The integration of wastewater heat pumps (using purified water) in district heating systems is analyzed in this paper. The simulation procedure is proposed to analyze the impacts of stochasticity of purified water temperature and flow to heat pump integration and operation. The analysis includes calculation of the daily and seasonal coefficient of performance, as well as fossil fuel savings and CO2 emission reduction due to wastewater heat pump use. The proposed procedure is implemented for the case study in ...Dejan Ivezić, Marija Živković, Dimitrije Manić, Aleksandar Madžarević, Boban Pavlović, Dušan Danilović.

Konceptualni model hidrogeotermalnog sistema šire okoline Brusa - geološki, geofizički i hidrogeološki uslovi / Conceptual model of hydrothermal system of Brus area - geological, geophysical and hydrogeological condition
Dejan Milenić, Ana Vranješ, Marinko Toljić, Ivana Vasiljević, Natalija Radosavljević, Matija Ognjanović (2024)Na širem području Brusa izvedena su naučna multidisciplinarna istraživanja za potrebe ocene geotermalnog potencijala sa zadatkom de9inisanja uslova formiranja geotermalnih i termomineralnih resursa. Interpretacijom podataka zaključeno je da je na predmetnom terenu formiran "hibridni" hidrogeotermalni sistem, koji sadrži elemente sistema u rov-strukturi i elemente konvektivnog hidrogeotermalnog sistema sa rezervoarom u pokrivaču granitoidne intruzije. Sistem čine dva nezavisna hidrogeotermalna rezervoara. Prvi rezervoar formiran je u gornjokrednim krečnjacima na dubini od oko 1550 m.

A Model for Determining Fuzzy Evaluations of Partial Indicators of Availability for High-Capacity Continuous Systems at Coal Open Pits Using a Neuro-Fuzzy Inference System
This paper presents a model for determining fuzzy evaluations of partial indicators of the availability of continuous systems at coal open pits using a neuro-fuzzy inference system. The system itself is a combination of fuzzy logic and artificial neural networks. The system availability is divided into partial indicators. By combining the fuzzy logic and artificial neural networks, a model is obtained that has the ability to learn and uses expert judgment for that learning. This paper deals with the ...системи, континуални системи експлоатације (роторни багер-транспортер-дробилично постројење), рударство, расположивост, меко рачунарство, фази логика, ANN, ANFISMiljan Gomilanović, Miloš Tanasijević, Saša Stepanović, Filip Miletić.

Laboratory testing of fly ash
Fly ash is one of the most common waste materials created by burning of coal. It is composed of smaller particles, consisting mainly of aluminosilicate glass, mullite and quartz, which are collected by electrostatic separators (filter) of gaseous products arising from the combustion of coal.
