Engineering Proceedings, Volume 100, Issue 1

The 14th International Scientific Conference TechSys 2025—Engineering, Technologies and Systems was organized by the Technical University of Sofia, Plovdiv Branch, within the frame of “Science Days of Technical University of Sofia”...

In submitting conference proceedings to Engineering Proceedings, the volume editors of the proceedings certify to the publisher that all papers published in this volume have been subjected to peer review administered by the volume editors [...]

This study presents a comparative analysis between simulated results obtained using PVSol Expert software and real operational data from a functioning photovoltaic power plant (PVPP) located in Plovdiv, Bulgaria. The primary objective is to evaluate...

Global sequence alignment remains a fundamental technique in bioinformatics, yet its large-scale application is often limited by computational demands. In this work, we explore the impact of optimal global sequence alignment on sequence similarity by...

This article presents the design, development, and evaluation of an AI-based assistant tailored to support users in the application of the Specific Operations Risk Assessment (SORA) methodology for unmanned aircraft systems. Built on a customized lan...

System identification—originating in the 1950s from statistical theory—has since developed a wealth of algorithms, insights, and practical expertise. We introduce Kolmogorov–Arnold neural networks (KANs) as an interpretable alternat...

One of the crucial tasks for autonomous robots is learning to safely navigate through obstacles in real-world environments. An intelligent robot must not only perform the assigned task but also adapt to changes in its environment as quickly as possib...

This study provides a combined numerical and analytical investigation of fatigue crack growth in compact tension specimens made of 42CrMo4 steel. Through simulations in ANSYS Workbench (SMART Crack Growth module) and numerical modeling in MATLAB, the...

This paper discusses a new method and sensor for the detection of ultra-low masses, such as those of viruses and biomarkers. The sensor contains three microcantilevers with a common substrate that vibrates. The detection method processes phase-shifte...

This paper presents studies of a digital twin system. A conceptual model of the system is proposed to be used to control an industrial robot and can be integrated into different fields of application such as industry, manufacturing, farming, livestoc...
