Evaluation of sand p–y curves by predicting both monopile lateral response and OWT natural frequency
Studia Geotechnica et Mechanica, 2022 Extending the use of the p–y curves included in the regulation codes API and DNV to design large-diameter monopiles supporting offshore wind turbines (OWTs) was unsuccessful as it resulted in an inaccurate estimation of the monopile behavior.

Simplified analysis of structures using applied element method [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2021 The Applied Element Method (AEM) is a numerical method of structural analysis. The degrees of freedom are located at the centroid of an element, which is rigid. In AEM, many pairs of springs are provided on the faces of the element. Although the AEM is

Improved two-dimensional cracked finite element for crack fault diagnosis
Computer Assisted Methods in Engineering and Science, 2017 In this paper the two-dimensional finite element with an embedded edge crack proposed by Potirniche et al. (2008) is improved further for crack depth ratios ranging up to 0.9 and for predicting the natural frequency of a cracked beam more accurately ...

Tuning of human modulation filters is carrier-frequency dependent [PDF]
, 2013 Recent studies employing speech stimuli to investigate 'cocktail-party' listening have focused on entrainment of cortical activity to modulations at syllabic (5 Hz) and phonemic (20 Hz) rates.
