"RUBBER TUBE PERCUSSION."

A tube concept in rubber viscoelasticity

A constitutive model is derived for the time-dependent response of particle-reinforced elastomers at finite strains. An amorphous rubbery polymer is treated as a network of long chains linked by permanent junctions (chemical crosslinks, entanglements and filler particles). A strand between two neighboring junctions is thought of as a sequence of mers whose motion is restricted to some tube by s...

Cranial percussion.

Percussion of the skull dates from a time when there were virtually no radiological methods for examining the skull and brain. Three apparently independent contributions appeared within the years 1893-1895. The sound elicited, tenderness, and auscultatory percussion have each been employed for diagnostic purposes, but have long been superseded.

Chest percussion.

The direct method of chest percussion, first described by Auenbrugger but disseminated by Corvisart, has rapidly been replaced by the indirect or digitodigital method. Chest percussion has not been evaluated by modern acoustic means, so that our present knowledge of the method does not consistently differ from the 19th century approach. Auscultatory percussion is not superior to conventional pe...

Mobile Device Percussion Parade

In this paper, we present the “Mobile Device Marching Band” (MDMB) as a new mode of musical performance with mobile computing devices. We define an MDMB to be, at its most general, any ensemble utilizing mobile computation that can travel as it performs, with the performance being independent of its location. We will discuss the affordances and limitations of mobile-based instrument design and ...
