, which helps them to propagate collectively as concentric patterns of swarms with high bacterial density while moving up in the nutrient gradient. The cell-to-cell signaling in bacterial swarm via......
during and after the rainfall are revealed. 5 A case study After the discussion of two academic seepage models, a real residual slope will be discussed in this section. The high cutting slope......
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......
to be processed was 304 stainless steel, which has good processing performance and high toughness, and is widely used. Experimental studies were performed using three-level three-factor orthogonal......
is an underground two-story station with a main length of 180 m and was constructed via island-type excavation. The maximum excavation dimensions of the station tunnel are 22.16 m wide and 19.21 m high... and -7.335 MPa, respectively). Each tunnel is subjected to high compressive stress at the inverted arch, and because of the triangular layout of the tunnel, the arch waist of the running tunnels......

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......
