    Investigation of the Geometrical Deterioration Process of Tramway Superstructure Systems – A Case Study
    (2026) Jóvér, Vivien; Major, Zoltán; Németh, Attila; Sysyn, Mykola P.; Kurhan, Dmytro; Fischer, Szabolcs
    ENG: Tramway tracks deteriorate over time due to operational loads, environmental conditions, and structural factors. This study analyzes the geometric degradation of Budapest's tramway tracks using long-term measurements. Track gauge and longitudinal level were assessed with the TrackScan 4.01 instrument to evaluate deterioration across different superstructure types. Findings indicate that concrete slab tracks experience gauge widening, while embedded rail systems tend to narrow under similar conditions, with structural design playing a greater role than traffic intensity. Measurement limitations highlight the need for improved monitoring tools. These insights support more effective maintenance strategies, ensuring greater durability and sustainability.

    Optimization of Metal Can (bottle) Shapes for Maximizing Waste Container Capacity
    (2026) Titrik, Ádám; Kurhan, Dmytro; Sysyn, Mykola P.; Fischer, Szabolcs
    ENG: Effective waste management is key to creating more sustainable cities. This study explores a straightforward but impactful way to enhance waste collection efficiency – by optimizing the compaction of metal cans. Various methods of compressing metal containers, including hand and foot compression (middle, full diameter, and full height), were tested to see how much they could reduce the volume of these cans. Our simulations showed that full-height and full-diameter compression were the most effective, significantly increasing container capacity by minimizing empty space. This approach is not only practical but scalable, offering waste management operators a clear pathway to improving resource efficiency. Beyond the immediate benefits of reduced collection frequency and lower fuel consumption, this method contributes to broader sustainability goals by minimizing the carbon footprint associated with waste management. These findings have wide-ranging implications, from urban policy-making to everyday waste disposal practices, highlighting a simple yet transformative step toward a cleaner environment.
