Spectral roughness of glaciated bedrock geomorphic surfaces: Implications for glacier sliding [PDF]
, 2000 A microroughness meter (MRM) was used to measure the high-frequency roughness of a number of geomorphic surfaces in the forefield of Glacier de Tsanfleuron, Switzerland.

TEM characterisation of near surface deformation resulting from lubricated sliding wear of aluminium alloy and composites [PDF]
, 2007 Aluminium alloy composites have been extensively investigated for use in tribo-contact applications, however little detailed literature exists on the sub-surface microstructural evolution as a result of lubricated sliding wear.

Does water lubrication affect friction differently for rocks and soils? Evidence and open questions
Studia Geotechnica et Mechanica, 2022 The present paper focuses on the shear strength exhibited by rocks and soils when sliding along dry and wet surfaces, with this mechanism of failure being strongly related to the water lubrication phenomenon.

Sliding bifurcations and non-determinism in systems with switching [PDF]
, 2011 Dynamical events associated with loss of determinacy in piecewise-smooth dynamical systems are reviewed. The causes of non-determinacy are discussed, and the conditions for their occurence in general systems are derived. These events can be characterized

Continuous Nearest Neighbor Queries over Sliding Windows [PDF]
, 2007 —This paper studies continuous monitoring of nearest neighbor (NN) queries over sliding window streams. According to this model, data points continuously stream in the system, and they are considered valid only while they belong to a sliding window that ...
