Principal component analysis and multidimensional scaling of the morphological traits of olive clones
This study analyzed the morphological traits of the Žutica olive variety, assessing its variability through statistical methods. Principal component analysis (PCA) identified the first three components as having the greatest influence on the grouping of Žutica clones. Fruit and endocarp length, width, and weight, as well as pulp weight, were associated with PC1, while the shape index of both fruit and endocarp was linked to PC2. PC3 included the leaf shape index, internode length, pulp percentage,...

Radiation hazard indices associated with natural radioactivity in building materials in Montenegro
Abstract
Eleven building materials (95 samples in total) have been analyzed for 226Ra, 228Ra (232Th series), and 40K activity using High Purity Germanium (HPGe) spectrometry, and concentrations are found to be in the range (2.2–549), (0.3–161), and (2.7–1034) Bq kg−1, respectively. Statistical analyses showed a moderate positive linear correlation between 226Ra and 228Ra, and significant differences in the mean radionuclide concentrations among ceramic tile, brick, granite, and...

A Portable Solar-Powered Edge-AI System for Livestock Monitoring in Off-Grid Mountain Pastures: System Design and Field Validation
Highland pastures in Montenegro, known as katuns, are seasonal settlements without grid power or network coverage and which are located where conventional monitoring is unfeasible. This study presents a solar-powered, off-grid system for livestock and environmental monitoring. It integrates, into a single portable unit, a solar power station, an edge-AI computer, a camera, environmental sensors, a LoRaWAN gateway, and a cellular router for backhaul. All parts are pre-wired in a modular enclosure,...
