Estimating acoustic wave dispersion in pipelines filled with water is studied using theoretical analysis and laboratory experiments. Previous methods for experimentally estimating the dispersion of the propagating modes require multiple spatial measu

The pressure damping occurring in pressurized pipes with a leak during transients has been examined as a diagnostic tool – the so-called transient damping method (TDM) – mainly from the theoretical and numerical point of view. On the contrary, th

For Modeling the transient flow in a pipeline by Frequency Response Method (FRM), the nonlinear terms of the governing equations and boundary conditions should be linearized. Significant nonlinearities are associated with the steady friction and valv

Monitoring pipeline thinning and material degeneration is becoming important for water-filled pipeline condition assessment. In this paper, an inverse method is proposed for estimating a pipeline's dimensional and material parameters using the disper

Slit-like and Trk-like (Slitrk) family members are leucine-rich repeat (LRR)-containing neuronal transmembrane proteins. Slitrks have been highlighted as key synapse organizers at neuronal synapses through interactions with specific members of the pr

Measurement and characterization of acoustic noise in water pipeline systems across the 10 Hz to 100 kHz acoustic frequency band are reported in this paper. The motivation for the noise characterization is to support the development of acoustic signa
