This paper is based on the DVB-C standard,the feedback loop is adopted to realize symbol synchronization,in which the M&M algorithm is choosing into the timing error detector.

The ladder style retaining wall is designed by "m" method,which prevents the retaining wall from whole slippage and hunching effectively.

Using power-series method the differential equation of "m" method is resolved; at the same time practical formula is also derived for internal force and displacement calculation of the pile, which is under the interaction of flexural moment and horizontal force at pile tip.

Two numerical solutions of laterally loaded piles installed in multi-layered soils by m method;

Nonlinear m method for piles under lateral load

The traditional m method and the large-scale finite element software MSC.
