Piping and woody plants in peatlands: Cause or effect? [PDF]
Water Resources Research, 2005 This paper presents, for the first time, evidence to show that Calluna species are one causative factor of piping in blanket peat catchments. Ground-penetrating radar survey on 960 plots illustrated that piping was prevalent throughout blanket peats ...

In-pipe Robotic System for Pipe-joint Rehabilitation in Fresh Water Pipes [PDF]
arXiv, 2019 The robot's objective is to rehabilitate the pipe joints of fresh water supply systems by crawling into water canals and applying a restoration material to repair the pipes. The robot's structure consists of six wheeled-legs, three on the front separated 120{\deg} and three on the back in the same configuration, supporting the structure along the ...

The Canonical Bijection Between Pipe Dreams and Bumpless Pipe Dreams [PDF]
International Mathematics Research Notices 2023, 2021 We present a direct bijection between reduced pipe dreams and reduced bumpless pipe dreams by interpreting reduced compatible sequences on bumpless pipe dreams and show that this bijection preserves Monk's formula, establishing its canonical nature.
