by researchers in the Soviet Union in 1950. A sliding mode control (SMC) differs from a simple relay controller because it relies on high-speed switching of control values and can be changed..., its control signal is discontinuous and produces adverse chattering phenomena [28] that may stimulate the high- frequency dynamics of system and, in the worst case, cause system instability......

aggregate and rubber particles to develop high-performance self-compacting concrete, and LIU et al [10] studied the fatigue properties of rubber-modified recycled aggregate concrete. Their results show... porosity of high-performance rubber concrete increases by 3.45% and the small pore volume of 10-100 nm is mainly controlled by rubber content. To promote the application of recycled crumb rubber concrete......
