Investigation of the Reoxidation and Material Behavior of Directly Reduced Pellets and Fines Under Simulated Rail Transport Conditions

open access: yessteel research international, EarlyView.
The study investigates the reoxidation behavior of DRI pellets (Midrex and H2‐reduced) under realistic conditions, considering the test parameters of temperature, humidity, storage duration, particle size (including fine fraction), and container geometry. The samples are analyzed based on mass changes.

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

open access: yesStructural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Assessing Capability Complexity Using Enterprise Architecture Framework

open access: yesSystems Engineering, EarlyView.
ABSTRACT This study proposes a structured and quantitative methodology to evaluate the holistic complexity of system‐of‐systems (SoSs), employing the Zachman Architecture Framework (ZAF) as its foundational analytical tool. A five‐phase analytical procedure is developed and empirically validated, encompassing: (1) refinement of complexity measures, (2)

FL‐Offshore: A Federated Learning Framework for Predictive Maintenance in Brazilian Offshore Production Scenario

open access: yesArtificial Intelligence for Engineering, EarlyView.
ABSTRACT Offshore oil production in Brazil relies on Floating Production Storage and Offloading (FPSO) units, where failures in rotating machinery motivate machine learning–based predictive maintenance. Centralised training is impractical due to privacy constraints, heterogeneous and highly imbalanced local datasets and unreliable satellite ...
