Cylindrical drum         
CLASS OF MUSICAL INSTRUMENTS
Cylindrical drums are a category of drum instruments that include a wide range of implementations, including the bass drum and the Iranian dohol. Cylindrical drums are generally two-headed and straight-sided, and sometimes use a buzzing, percussive string.
Cylindrical harmonics         
BESSEL FUNCTIONS FOR INTEGER Α
Cylindrical harmonic
In mathematics, the cylindrical harmonics are a set of linearly independent functions that are solutions to Laplace's differential equation, \nabla^2 V = 0, expressed in cylindrical coordinates, ρ (radial coordinate), φ (polar angle), and z (height). Each function Vn(k) is the product of three terms, each depending on one coordinate alone.

Miller cylindrical projection

The Miller cylindrical projection is a modified Mercator projection, proposed by Osborn Maitland Miller in 1942. The latitude is scaled by a factor of 45, projected according to Mercator, and then the result is multiplied by 54 to retain scale along the equator. Hence:

or inversely,

where λ is the longitude from the central meridian of the projection, and φ is the latitude. Meridians are thus about 0.733 the length of the equator.

In GIS applications, this projection is known as: "ESRI:54003 – World Miller Cylindrical".

Compact Miller projection is similar to Miller but spacing between parallels stops growing after 55 degrees.
