Modern cities face traffic congestion, inefficient use of resources, and pollution, challenges that are intensified by urbanization. The smart city concept, based on the application of the Internet of Things (IoT), enables more efficient management of urban infrastructure and improvement of the quality of life. This paper examines the application o...

This paper presents the applicability of video-based image processing techniques for discharge estimation in a laboratory channel. Surface velocities were determined using the optical flow (OF) method, and the corresponding discharge was estimated based on these measurements. The obtained results were compared with values measured using a discharge...

Low-enthalpy subgeothermal energy represents one of the most stable and environmentally friendly renewable energy sources for heating and cooling buildings. The efficiency of these systems largely depends on the geological and hydrogeological characteristics of the soil in which the geoprobes are installed in the case of the "soil-water" system or ...

Shallow geothermal energy remains underutilized in the Danube Region despite its potential to reduce fossil fuel dependency and support EU climate goals. The Danube GeoHeCo project addresses this gap by fostering transnational cooperation, aiming to promote hybrid ground-source heat pump (GSHP) solutions. Key outputs include Transnational Action Pl...

The Ibarac tunnel was excavated as part of the Rožaje bypass project in Montenegro. Nearly half of the excavation was carried out in glaciofluvial sediments consisting of brown sandy clay with gravel and rock fragments. As the original design did not anticipate tunneling through such deposits, the subsequent adoption of overly optimistic geotechnic...

This paper examines the historical evolution of computer-aided design (CAD) and building information modeling (BIM) software in architecture, civil engineering, and geodesy. The development of digital design technologies is analyzed through several key phases, from the early experimental CAD systems of the 1960s and 1970s to the expansion of person...

Green architecture is recognized not only for its environmental and social advantages but also for its financial and market benefits. The study combines a quantitative analysis of operational cost reduction and investment return with a qualitative assessment of property value and socio-economic impacts. Case studies and literature illustrate both m...

Nature-like fish passes are complex hydraulic–ecological systems whose performance is often assessed through fragmented monitoring approaches. This paper proposes an integrated KPI-based framework for the evaluation and classification of fish pass functionality, combining biological, hydraulic, and operational indicators within a structured m...

Urban heritage sites that have undergone radical spatial transformation present major challenges for conservation practice and urban planners. This paper examines the research methodology behind the revitalization project of the former Tutunović Podrum site in the Palilula municipality of Niš. Once the geometric and social centre of the dist...

In this paper, the authors address the inspection of concrete structures using ground-penetrating radar (GPR) scanning technology. The main idea is focused on the inspection of a concrete structure for the purpose of detecting reinforcement or objects with a circular cross-section. The analysis includes both dry and wet concrete, as well as metalli...
