To study the dynamic characteristics and microstructure of nano-CaCO3 remolded soft clay under cyclic loading, GDS dynamic triaxial and NMR tests were conducted to analyze its dynamic stress-strain, dynamic elastic modulus, damping ratio, and micro pore changes.The results show that as the content of nano-CaCO3 increases and the confining pressure
A variety of algorithms allows gesture recognition in video sequences.Alleviating the need for interpreters is of interest to hearing impaired people, since it allows a great degree of self-sufficiency in communicating their intent to the non-sign language speakers without the need for interpreters.State-of-theart in currently used algorithms in th
