Experiments on wave turbulence : the evolution and growth of second sound acoustic turbulence in superfluid 4He confirm self-similarity. [PDF]
, 2010 We report our experiments on the formation of second sound acoustic turbulence in superfluid 4He. The initial growth in spectral amplitude follows power laws that steepen rapidly with increasing harmonic number n, corresponding to a propagating front in ...

Effects of the pipe-joints on acoustic emission wave propagation velocity [PDF]
, 2008 In jointed-pipes, a variety of different acoustic emission (AE) waves can be generated by way of mode conversion, wave reflection and wave transmission from a joint. This can lead to interference waves as resulting complicated signals propagate along the

Development of a combined surface plasmon resonance/surface acoustic wave device for the characterization of biomolecules [PDF]
, 2009 It is known that acoustic sensor devices, if operated in liquid phase, are sensitive not just to the mass of the analyte but also to various other parameters, such as size, shape, charge and elastic constants of the analyte as well as bound and viscously

ST Quartz Acoustic Wave Sensors with Sectional Guiding Layers [PDF]
, 2008 We report the effect of removing a section of guiding layer from the propagation paths of ST-quartz Love wave sensors; this offers the ease of fabrication of a polymer guiding layer whilst retaining the native surface of the quartz which may then be used
