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...

Blackwater, the wastewater stream with the highest sanitary and energy load, is increasingly seen as a resource within circular urban systems. This paper explores its valorization through anaerobic digestion and decentralized planning. Using Banja Luka as a case study, key energy, economic, and spatial thresholds for local treatment feasibility are...

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 ...

The paper examines the key factors shaping quality of life in contemporary apartments, in line with 21st-century needs, with a focus on the post-pandemic period. The COVID-19 pandemic altered housing patterns: during restricted mobility, the apartment took on the functions of home, work, recreation, and recovery, thereby redefining comfort criteria...

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...

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...

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 ...

Due to the decreasing resources of non-renewable fresh water and climate changes leading to more frequent intense rainfalls, designed solutions are desired to manage rainwater in accordance with the principles of blue-green infrastructure. This paper discusses four concepts of rainwater management for a warehouse hall using solutions such as drain...
