Harmonic Growth—The Harmonic Number Applied to ROI, Business Scaling, Nth Plant Economics, Micro Combined Heat and Power (mCHP), Biorefineries, and Biochar Production

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Scaling is a topic of utmost importance in business. When to scale and how has been the subject of countless books and seminars. This paper looks at modular businesses that have income and costs directly proportional to the number of units.

NExT‐LF: A Novel Operational Modal Analysis Method via Tangential Interpolation

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Operational modal analysis (OMA) is vital for identifying modal parameters under real‐world conditions, yet existing methods often face challenges with noise sensitivity and stability. This study introduces NExT‐LF, a novel method that combines the well‐known Natural Excitation Technique (NExT) with the Loewner Framework (LF). NExT enables the

Monitoring of Corrosion Damage by Using iFEM Methodology

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Marine environment is a harsh environment that can cause major issues for marine structures while operating in this environment, including fatigue cracking and corrosion damage, which can yield catastrophic consequences, such as human life losses, financial losses, environmental pollution, and so forth.

Prediction of the Behaviour of Monopiles Under Drained Two‐Way Cyclic Lateral Loading in Sand

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The monopile is considered as one of the preferred geotechnical foundations for the offshore wind energy converter; therefore, its cyclic behaviour is one of the major concerns in the design. In the current design approaches, the prediction of two‐way cyclic behaviour mainly depends on empirical equations, in which the specific site conditions
