AI Generative Topology Hallucination and Latent Defect Sensitivity

Mohamed Fayez Elnagar, Structural Consultant, Ph.D. Applicant at The University of Edinburgh, Forensic Engineer, Certified Expert at Ministry of Justice, ACI member. Email: drmfayez@proton.me

The utilization of AI-driven generative design and topology optimization algorithms allows structural engineers to create complex architectures with high material efficiency. By inputting boundary load cases, boundary conditions, and volume targets, neural networks remove under-stressed material, forming intricate conf...

Structural Thawing and Foundation Degradation in Permafrost Regions

Mohamed Fayez Elnagar, Structural Consultant, Ph.D. Applicant at The University of Edinburgh, Forensic Engineer, Certified Expert at Ministry of Justice, ACI member. Email: drmfayez@proton.me

The stability of civil infrastructure—including pipelines, transportation networks, and industrial facilities—constructed in sub-polar and arctic regions heavily relies on the mechanical stability of permafrost (permanently frozen ground). Traditionally, structural foundations were engineered assuming that the underlyi...

Size Effect and Brittle Fracture Vulnerability in Heavy Structural Steel Connections

Mohamed Fayez Elnagar, Structural Consultant, Ph.D. Applicant at The University of Edinburgh, Forensic Engineer, Certified Expert at Ministry of Justice, ACI member. Email: drmfayez@proton.me

The economic drive to optimize the design of mega-span bridges, industrial facilities, and the lower transfer stories of super-tall buildings has necessitated the use of heavy structural steel components and thick plate connections, often exceeding thicknesses of 100 mm. Traditional structural engineering paradigms ass...

Anisotropy and Shear Vulnerability in 3D-Printed Concrete Elements

Mohamed Fayez Elnagar, Structural Consultant, Ph.D. Applicant at The University of Edinburgh, Forensic Engineer, Certified Expert at Ministry of Justice, ACI member. Email: drmfayez@proton.me

The additive manufacturing of concrete components through robotic extrusion eliminates the need for traditional formwork, yet it introduces a pronounced mechanical anisotropy dilemma. When concrete filaments are deposited sequentially, the material properties diverge significantly along different directional axes. The...

Abschätzung der Empfangsqualität bei Smart Metern: Vergleich von Mobilfunk und Power Line Communication

Bernegger, Andreas

Ziel dieser Arbeit ist die Beantwortung der Frage, welche Kommunikationstechnologie für die Anbindung von Smart Metern im Versorgungsgebiet der Netz OÖ die höchste technische Eignung aufweist. Dazu wurden die beiden derzeit relevantesten Technologien Power Line Communication (PLC) und Point-to-Point (P2P) via Mobilfunk...

Supercritical Carbon Dioxide Curing Stresses and Microstructural Degradation

Mohamed Fayez Elnagar, Structural Consultant, Ph.D. Applicant at The University of Edinburgh, Forensic Engineer, Certified Expert at Ministry of Justice, ACI member. Email: drmfayez@proton.me

Accelerating the curing process of concrete by injecting carbon dioxide—specifically in its supercritical state (sCO2)—represents a revolutionary method to capture carbon permanently within building materials while rapidly achieving high early-age strength. During this process, the dissolved gas reacts with calcium sil...

Quantum Sensing Limitations and Electromagnetic Interference in Infrastructure Monitoring

Hydrogen Storage Vessel Fatigue and High-Pressure Degradation

Mohamed Fayez Elnagar, Structural Consultant, Ph.D. Applicant at The University of Edinburgh, Forensic Engineer, Certified Expert at Ministry of Justice, ACI member. Email: drmfayez@proton.me

The global shift toward a clean hydrogen economy requires the design and deployment of massive pressure vessels and composite-wrapped storage tanks to contain high-pressure or cryogenic liquid hydrogen. Unlike conventional natural gas or petroleum storage, hydrogen introduces unique mechanical and material challenges d...

What can prosodic transfer tell us about L2 prosody acquisition? Data from Brazilian Portuguese Learners of English

Thales Buzan

O presente trabalho investiga a aquisição da prosódia em segunda língua (L2), com foco na transferência prosódica do português brasileiro (PB) para o inglês, a partir de dados de produção e percepção de sentenças declarativas de foco amplo e perguntas totais neutras. O estudo tem como objetivos analisar (i) a produção...

Elastic Rebound and Dynamic Rockbursts in Ultra-Deep Geo-Structures

Mohamed Fayez Elnagar, Structural Consultant, Ph.D. Applicant at The University of Edinburgh, Forensic Engineer, Certified Expert at Ministry of Justice, ACI member. Email: drmfayez@proton.me

The construction of strategic mega-infrastructure—such as deep underground scientific laboratories, high-level radioactive waste repositories, and ultra-deep transit tunnels excavated at depths exceeding 3 to 5 kilometers beneath the Earth's surface—introduces a profound geotechnical and structural design dilemma: elas...
