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. This ...Uroš Đurić, Miloš Marjanović, Zoran Radić, Biljana Abolmasov.

A multi-criteria approach for assessing the potential of renewable energy sources for electricity generation: Case Serbia
When assessing the potential of renewable energy alternatives for electricity generation, it is necessary to implement a multi-perspective approach that includes economic, technical, environmental, and socio-political criteria. For the evaluation of criteria and alternatives, the Fuzzy Analytical Hierarchy Process (FAHP) method is applied. The obtained weights are formed according to the values of energy indicators and expert judgments.

Utvrđivanje eksplotacionih učinaka sistema na otkrivci na površinskom kopu Tamnava-Zapadno polje primenom Fuzzy Topsis metode
Planiranoj proizvodnji uglja na površinskim kopovima prethodi nesmetano i kontinuirano otkopavanje otkrivke. Kako bi se obezbedila potrebna količina uglja, sistemi na otkrivci moraju uvek biti korak ispred u dinamici razvoja kopa. Velika produktivnost, visoki kapaciteti i dobar koeficijent vremenskog iskorišćenja, treba da budu odlika rada sistema putem kojih se vrši otkopavanje otkrivke. Kroz ovaj rad izvršena je analiza eksploatacionih učinaka za posmatrani period po smenama, kako bi se utvrdilo koja je od pomenutih smena ostvarila najbolje rezultate.Marko Lazić, Filip Miletić, Lazar Žujović.
