A Simulation Model of Administrative Buildings: Assessing Their Impact on Energy Performance

The construction sector is a complex industry whose growth and development are closely associated with overall economic expansion and the circular economy. Within this sector, Building Energy Simulation (BES) is widely employed to evaluate and compare the energy performance of pr...

Minimum Bisection Problem: Machine learning-based penalty parameter tuning for optimization on quantum annealers

The Minimum Bisection Problem is a fundamental NP-hard problem with applications in parallel computing, network design, and large-scale data processing. When formulated as a Quadratic Unconstrained Binary Optimization problem for quantum annealing, solution quality depends critic...

ESG and firm valuation: causal effects versus predictive relevance

Abstract This study examines the relationship between environmental, social, and governance (ESG) performance and firm valuation, with a particular emphasis on distinguishing between causal effects and predictive relevance. Using a panel dataset of publicly listed firms, the anal...

University Students’ Perceptions of Gamified Learning: A Comparison of Students with and Without Prior Experience

The growing integration of gamification and digital technologies in higher education has led to increasing interest in students’ perceptions of gamified learning environments. While existing research predominantly focuses on the effectiveness of gamification in enhancing motivati...

Comprehensive Design and Structural Verification of a Tubular Steel Metal–Hydride Storage Vessel for Hydrogen Separation and Storage

Hydrogen storage and separation remain major technical challenges limiting the broader implementation of hydrogen-based energy systems. Metal–hydride alloys offer a promising solution because they enable reversible hydrogen storage within their crystal structure and can selective...

Effects of Recycled ABS Content on Extrusion Stability, Diameter Variability, and Mechanical Response of Filaments for FFF/FDM Printing

This study addresses the production of 3D printing filament by extrusion from acrylonitrile butadiene styrene blends containing virgin and recycled material. The effect of recycled acrylonitrile butadiene styrene content on selected quality indicators was investigated, with parti...
