Assessment of the accuracy of the crossed-cylinder aberroscope technique
Journal of the Optical Society of America A, 1998 Simulations of the optics of the Howland crossed-cylinder aberroscope technique show that errors in alignment, data collection, and analysis can lead to unexpected asymmetries of the determined aberrations in a rotationally symmetric system. In particular, coma can be incorrectly indicated.

Relaxation of residual stresses in a surface-hardened rotating cylinder under creep conditions [PDF]
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2022 A technique for calculating the relaxation of residual stresses in a cantilevered rotating cylinder after the procedure of surface plastic deformation under creep conditions has been developed, taking into account the effect of a stepwise change in the ...

Journal of Marine Science and Engineering, 2021 Flexible cylinders, such as marine risers, often experience sustained vortex-induced vibrations (VIVs). Installing helical strakes on a riser is the most widely used technique to mitigate VIVs. This study was inspired by the giant Saguaro Cacti which can

International Journal of Naval Architecture and Ocean Engineering, 2021 Vortex-Induced Vibration (VIV) is a major contributor to the fatigue damage of marine risers which are often arranged in an array configuration. In addition to helical strakes and fairings, studies have been strived in searching for possible VIV ...
