“This is remarkable,considering the sudden jumping,bending and twisting the wings are subjected to when flapping and the noise that is created by other birds.” “In the scientific world,the process used to remove this mechanical noise is called ‘damping’,which means the removal of mechanical...
Simcenter 3D Acoustics now supports visco-thermal effects that occur in small ducts Holes and gaps are often found in consumer electronic products, like smartphones near the speaker and microphone positions. You can simulate the (damping) effect these have on the sound, more accurately now, and ...
The tendency of bridges to be excited by eg soldiers marching in step is well known and troops are generally commended to walk randomly when crossing such structures. However, a long known but largely forgotten phenomenon exists where an oscillating structure will actually drive walkers into step ...
Chaos & Complexityare related; both are forms of“Coarse Damping”. Whilechaosis a form of coarse damping in“time”,Complexityon the other hand is a form of coarse damping in“Structure”. Complexityarises from the ubiquitous“Collaborative Interplay”of“Entropy & Symmetry-Breaking”in all natur...
It is in fact likely that almost all of the theory below extends to base spaces which are -finite rather than finite (for instance, by damping the measure to become finite, without introducing any further null events), although we will not pursue this further generalisation here. The ...

A skeg is a vertical tapering projection or an external structural feature at the aft of the vessel, about the centreline, directly attached to the vessel’s bottom shell plating, and mostly, but not necessarily, situated in front of the rudder. As it is not intrinsic to the main hull ...
spatial parameter, 0 < x = rωq/π < 3/4 (scaled to the CD radius, in natural units π/ωq = λq≈ 2rCD), the decay of the self-trapped em-field, from the centre to the periphery of the CD, is modulated by an envelope function F(x), expressing its exponential damping: ...
Earthquake Protection of Existing Structures with Limited Seismic Joint: Base Isolation with Supplemental Damping versus Rotational Inertia Edentulous patients were enrolled to the study in The Department of TMD Zabrze, Poland and in The Zahnarztpraxis in Germany, retrospectively, after the prosthodontic ...
