Methods for computing the transient near-field pressure of a planar aperture include the point-source method [1] and the

spatial impulse response (SIR) method [2,3,4]. Recently, a rapid single integral approach has been developed for continuous

wave (CW) computation for both circular pistons [5] and rectangular pistons [6]. A time domain solution to the lossless wave equation can be derived subject to an input pulse v(t),

which models the uniform normal velocity of the piston. Solving the wave equation in cylindrical coordinates yields the single-

integral solution:

This pulse is analytically decomposed into time and space dependent functions given by

•Spinal injuries can cause the body to not properly regulate its own temperature. •Hot or cold weather causes large swings in core temperature, severely impairing basic body functions. •Will design a wheelchair accessory which regulates body temperature. •A network of tubes circulates temperature-controlled liquid around an all-weather garment
