Terrestrial height anomalies are compared with anomalies derived from Global Geopotential Models (GGMs) developed within the GOCO initiative. The analysis examines the influence of epoch differences on geometric heights. Terrestrial anomalies are determined from ellipsoidal heights obtained by GNSS and from precise levelling data. Ellipsoidal heigh...

In the modern world, automatic classification of buildings from orthophoto images has become critical task in various domains, including urban planning, geographic mapping and infrastructure change monitoring. Traditional building detection methods rely on manual procedures or classical image processing algorithms, which often lead to limited accur...

The Knićanin–Čenta subcatchment area, located in Central Banat, is a fertile agricultural region whose water regime is significantly influenced by the water levels of the surrounding rivers—the Danube, Tisa, Begej, as well as the Karaš canal. During May and June 2019, while the TurkStream gas pipeline was under construction, the ...

This study presents a seismic capacity assessment of a reinforced concrete structure in central Banja Luka, Bosnia and Herzegovina, using nonlinear dynamic analysis in OpenSees under Python environment. Site specific soil conditions, characterized by dynamic amplification factors of approximately 1.2, are incorporated into the analysis. Structural ...

This article provides a practical framework for the application of ultra-high-performance fiber-reinforced concrete (UHPFRC) in road bridges. Most of these bridges, constructed with reinforced or prestressed concrete according to mid-20th-century European practices, now face significant durability challenges. The rehabilitation of existing bridges ...

The application of seismic design codes is crucially important for the seismic safety of the built environment developed in earthquake prone regions. However, there are also buildings built before the introduction of seismic design codes. Seismic risk assessment is a useful process which can help identify the seismic safety of the urban regions wit...

The photogrammetric survey of buildings is a beneficial process to obtain accurate 3D data for facade inspection. It allows more straightforward monitoring of the state of the facade over time. An orthomosaic with an average ground sampling distance of 2.1 mm is created using close-range unmanned aerial vehicle photogrammetry. Ground control points...

EU Tunnel Directive 2004/54/EC aims to ensure a minimum level of safety for users in road tunnels in the Trans-European Road Network. EU member states are required to develop, at national level, their own detailed methodology for tunnel risk assessment. Along with that, ADR as the UN regulation in the field of dangerous good transportation by road,...

This study examines how parts of the public space that offer the possibility for standing contribute to vibrancy during public events. The aim of the paper is to investigate how different arrangements of temporary structures affect the positions of potential zones for standing and, therefore, the vibrancy of public spaces. Using Trg Slobode (Libert...

It has been observed that in earthquake-affected areas, structures with a configuration classified as torsionally irregular are more prone to damage than regular structures. Modern seismic provisions have introduced criteria for determining if the structure is torsionally sensitive and guidelines for designing them. Eurocode 8 prescribes criterion ...
