In this paper, we propose a class of monitoring statistics for mean shift in sequence high-dimensional observations. Inspired by the recent U-statistic based retrospective tests developed Wang et al.(2019) and Zhang al.(2020), advance approach to sequential problem developing new adaptive procedure that can detect both dense sparse changes real-time. Unlike where self-normalization was used the...

one and two dimensional contaminant transport by pure diffusion through single layer of fine grained soil was investigated using one and two dimensional laboratory models. these models simulates a simple hydrogeologic situation underneath a solid waste landfill comprising a fine grained soil overlying a bed rock. sodium chloride solution was sued as a contaminant source above a compacted clayey...
