The stability of a light sail riding on a laser beam is analyzed both analytically and numerically. Conical sails on Gaussian beams, which have been studied in the past, are shown to be unstable in ...
In the annals of design, seashells have a great pedigree. They inspired ancient architects to add those graceful spiral flourishes to the tops of their Grecian columns. The nautilus shell influenced ...
Research shows ECC shells can transform RC beam-column joints, enhancing load capacity and energy dissipation, crucial for earthquake-resistant design.
