Disk wrinkling under gravity

Wrinkling of Tympanic Membrane Under Unbalanced Pressure.

Mechanics of tympanic membrane (TM) is crucial for investigating the acoustic transmission through the ear. In this study, we studied the wrinkling behavior of tympanic membrane when it is exposed to mismatched air pressure between the ambient and the middle ear. The Rayleigh-Ritz method is adopted to analyze the critical wrinkling pressure and the fundamental eigenmode. An approximate analytic...

Gravity-Induced Wrinkling in Subscale, Singly Curved Parabolic Gossamer Membrane

Tape-Disk Join Strategies under Disk Contention

Large-scale data warehousing, data mining, and scientific applications require the analysis of terabytes of facts data accumulated over long periods of time. Tape libraries are suitable devices for storing such mass data. The online analytical processing (OLAP) of this data typically leads to long-running aggregation queries joining the tape-resident facts relation with disk-resident dimension ...

Discretized Gravity on the Hyperbolic Disk

We consider discretized gravity in six dimensions, where the two extra dimensions have been compactified on a hyperbolic disk of constant curvature. We analyze a fine-grained realization of lattice gravity on the hyperbolic disk at the level of an effective field theory for massive gravitons. It is shown that a nonzero curvature or warping in radial direction allows to obtain a strong coupling ...

Creasing-wrinkling transition in elastomer films under electric fields.

Creasing and wrinkling are different types of instabilities on material surfaces characterized by localized singular folds and continuously smooth undulation, respectively. While it is known that electric fields can induce both types of instabilities in elastomer films bonded on substrates, the relation and transition between the field-induced instabilities have not been analyzed or understood....
