E. Thorp introduced the following card shuffling model. Suppose the number of cards n is even. Cut the deck into two equal piles. Drop the first card from the left pile or from the right pile according to the outcome of a fair coin flip. Then drop from the other pile. Continue this way until both piles are empty. We show that if n is a power of 2 then the mixing time of the Thorp shuffle is O(l...

This study aims to investigate the barrier effect of front wall-soil-barrier interactions in sheet pile wharf structures. Berth 32 Jingtang Port was taken as prototype structure, and observation experiment, centrifugal model test, numerical calculation analysis were performed influence length pile, spacing D be...

The upper structure of high piled wharf in coastal soft soil area is loaded by waves or ships, which transferred to the foundation through pile foundation. force small and lasts for a long time, causes strength saturated clay vibration range decrease slowly, weakening effect gradually accumulates, resulting horizontal displacement In this paper, maximum residual are deduced calculated analytica...

Using the Berele/Remmel/Kerov/Vershik variation of the Robinson-Schensted-Knuth correspondence, we study the cycle and increasing subsequence structure after various methods of shuffling. One consequence is a cycle index for shuffles like: cut a deck into roughly two equal piles, thoroughly mix the first pile and then riffle it with the second pile. Conclusions are drawn concerning the distribu...
