Coupling of artificial intelligence methods in the development of hybrid intelligent systems
In this paper we present an approach which couples various artificial intelligence (AI) methods in the solution of complex problems that cannot adequately be solved by a single AI method. We argue that the resulting, hybrid intelligent systems (HIS) can be successfully implemented with the use of available AI software libraries. Different coupling methods are analyzed and a classification of hybrid systems based on the chosen method is given.

Debris-flow Susceptibility Assessment in Flow-R: Ribnica River Case Study
Debris flows are among the most dangerous erosional geohazards due to the fast rate of movement and long runout zones. Even though the initiation can be triggered in mountainous areas, inhabited and with steep slopes, their propagation and deposition can endanger not only buildings and infrastructure in the urbanized areas, but also threaten human lives. As these initiation areas usually represent unattainable terrains with rapid vegetation cover development, field observations and aerial photo analysis become high-demanding tasks. Consequently, medium-to-regional ...Ksenija Micić, Miloš Marjanović, Biljana Abolmasov .

Razvoj modela upravljanja cirkulacijom u postupku bušenja korišćenjem neuro fazi sistema zaključivanja
Seyed Ali S. Razeghi (2022)Gubitak isplake predstavlja nekontrolisano isticanje bušaćeg fluida kroz formacije kao što su kaverne, pukotine, ili drugi slojevi. Tradicionalne metode procene gubitka isplake se zasnivaju na primeni seizmičkih podataka ili pronalasku „mesta“ gubitka isplake na osnovu raspoloživih podataka iz susednih bušotina. Međutim, ove metode procene nisu pouzdane.‘ U disertaciji je izvršena analiza i procena uticaja parametara bušenja, geoloških faktora, karakteristika formacije i fluida na gubitak isplake kao i na formiranje fraktura u formacijama. Uspostavljeni su modeli koji podrazumevaju proces obrade ...Seyed Ali S. Razeghi. Razvoj modela upravljanja cirkulacijom u postupku bušenja korišćenjem neuro fazi sistema zaključivanja, Beograd : [S.

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. ...... all available geological, tectonic and other useful data. The 89 interpretation of VGG data is appropriate as long as all the limitations. of the applied method are considered. If that is the case, the information gained from VGG data can be valuable in different areas of exploration (S ...

Remedijacija otpadnih voda Rudnika prirodnim zeolitom
Igor Veličković (2024)U radu je razmatrano prečišćavanje otpadnih flotacijskih voda sa područja rudnika Rudnik prirodnim zeolitskim tufom sa planine Jastrebac. Prečišćavanje otpadnih flotacijskih voda sa područja rudnika Rudnik prirodnim zeoliskim tufom sa obronaka planine Jastrebac pokazala se veoma efikasnom. Naime, u tri otpadne flotacijske vode utvrđen je povišen sadržaj arsena, hroma, gvožđa, mangana, kao i nikla. Jednostavnim tretmanom zeolitskim tufom iz ovih voda uklonjeni su svi ovi elementi.

Pokazatelji recentne tektonske aktivnosti u speleološkim objektima Dževrinske grede (istočna Srbija)
Ana Mladenović, Jelena Ćalić (2022)Sistem Timočkog raseda predstavljen je sistemom desnih transkurentnih raseda generalnog pružanja sever – jug, koji su bili aktivni u periodu oligocena i miocena u okviru Karpato-balkanskog orogena. Početak njihove aktivnosti vezuje se za rotaciju tektonskih jedinica Karpato-balkanida (Dacia Mega Unit) oko rigidne Mezijske jedinice. Aktivnost ovih transkurentnih raseda je akomodirala ovu rotaciju, pa se smatra da je kumulativno kretanje duž Timočkog raseda tokom perioda njegove aktivnosti bilo do 100 km. Usled kompleksnih tektonskih rotacija, rasedi ovog sistema doveli su ...Ana Mladenović, Jelena Ćalić.

State and perspective of individual household heating in Serbia: A survey-based study
This paper presents the results of the household survey on individual household heating systems in Serbia. The survey was conducted in the period October to December 2020 with the participation of 1100 households with individual household heating systems. The information collected in the questionnaire can be separated into three main parts: basic household data, current heating system characteristics, and households’ perceptions and attitudes. The survey results provide unique and comprehensive information concerning individual household heating systems and the main ...Boban Pavlović, Dejan Ivezić, Marija Živković.

Steel Arch Support Deformations Forecast Model Based on Grey–Stochastic Simulation and Autoregressive Process
Relatively large deformations of the steel arch support in underground coal mines in the Republic of Serbia present one of the main problems for achieving the planned production of coal. Monitoring of the critical sections of the steel arch support in the underground roadways is necessary to gather quality data for the development of a forecasting model. With a new generation of 3D laser scanners that can be used in potentially explosive environments (ATEX), deformation monitoring is facilitated, while ...čelična podgrada, prognoza deformacija, vremenske serije, grey-stohastička simulacija, autoregresija, podzemni rudnik ugljaLuka Crnogorac, Suzana Lutovac, Rade Tokalić, Miloš Gligorić, Zoran Gligorić.
