The Past, Present and Future of Structural Health Monitoring: An Overview of Three Ages

Strain, Volume 61, Issue 1, February 2025.
ABSTRACT This paper presents an overview of the discipline of structural health monitoring (SHM), organised in terms of three proposed ages. The first age is delineated by the prehistory of SHM and the period where nondestructing testing methods evolved into an organised set of principles built upon physics‐based models; this age ended when the model ...

Application of Circulation Controlled Blades for Vertical Axis Wind Turbines

Energies, 2013
The blades of a vertical axis wind turbine (VAWT) rotor see an inconsistent angle of attack through its rotation. Consequently, VAWT blades generally use symmetrical aerofoils with a lower lift-to-drag ratio than cambered aerofoils tailored to maximise ...

Optimizing a Novel Wind Turbine for Sub‐Saharan Africa: A Techno‐Economic and Multicriteria Evaluation

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
Wind energy has emerged as a key contributor to the global renewable energy mix, yet much of sub‐Saharan Africa (SSA) remains underutilized due to predominantly low wind speeds and the limitations of conventional horizontal‐axis wind turbines (HAWTs).
