Researchers say they will test "wave heights, wave pressures and forces, flow velocities, wave overtopping, damage patterns and changes in cross-sections".
Propagating waves generated by leak noise reverberate in a pipe network system, as they encounter features such as changes in section, and resistance such as valves, and pipe junctions.
In this paper the approach is extended to the case of incident near field waves, reflection and transmission matrices being derived for the cases of a point support and a change in section.
The government plans major changes in Section 8 Housing Vouchers, rent subsidies for low-income families.
The different combinations of horizontal and vertical alignments and changes in the geometric standards between different sections (e.g. change in the lane width) have to be considered.
Expressions are derived which describe wave reflection at a boundary, reflection and transmission at a change in section and reflection and transmission at an attachment.
To illustrate the plausibility of our theoretical arguments and to illustrate concrete challenges, we explore trust issues in the German energy sector ("Trust and distrust as drivers of stability and change in ES transformation" section).
Overall, pool widening caused a predominantly local response, with change to pool hydraulics and no change in section-averaged velocity in the riffle beyond the initial widening of 10%.
There were no reproducible changes in sections of skin, muscle, fat, intestine, liver, kidney, spleen, or heart.
Pathological changes in sections of femoral bone marrows showed that irradiation reduced marrow cellularity, thereby resulting in the absence of erythroid, rare myeloid and megakaryocytic cells.
