Hanging Around in Non-Uniform Fields

The American Mathematical Monthly, 2015
AbstractWe define a family of curves, the n-catenaries, parameterized by the nonzero reals. They include the classical catenaries (n = 1), parabolas (n = 1/2), cycloids (n = −1/2), and semicircles ...

Uniform and non-uniform gravitational fields

Physics Education, 2018
Abstract According to Newtonian mechanics, the gravitational fields created by bodies with spherical symmetry (such as planets) are non-uniform. This may create the impression to undergraduate physics students that uniform gravitational fields are just an approximation.

Magnetoelectrolysis in non-uniform solenoidal fields

Journal of Applied Electrochemistry, 1978
In previous work on magnetoelectrolytic cells in uniform magnetic fields [ 1-3 ] preliminary findings have suggested that in non-uniform gradient fields the mass transport enhancement effect can further be increased. The effect was studied in more detail in a specially designed apparatus, shown in Fig.

Non-uniform field breakdown of gases

1988. Annual Report., Conference on Electrical Insulation and Dielectric Phenomena, 2003
The empirical breakdown law is extended to the evaluation of breakdown voltage under nonuniform field conditions. The effects of pressure and gap length are investigated. It is shown that, in nonuniform field conditions, the exponential relation between breakdown voltage and molecular density (pressure) is not affected.

Ray Computation for Non-Uniform Fields

The Journal of the Acoustical Society of America, 1946
A formula is derived which simplifies the computation and tracing of rays in non-uniform sound fields. In applying it, a field is first assumed to be equivalent to an array of horizontally homogeneous strata each with a uniform gradient of the speed of sound. Then the “range” of the ray through the whole array can be computed by the formula in one step,

The acoustic field in non-uniform layers

Journal of Sound and Vibration, 1975
The numerical solution of field problems with non-uniform media requires fidelity in the conversion of the mathematical description from continuous to discrete followed by efficient and accurate performance of the ensuing calculations. Here, the conversion process into a matrix equation has been accomplished with minimized distortion to the continuous ...

Harmonic Fields in a Non Uniform Plasma

IEEE Transactions on Plasma Science, 1974
The magnitudes of the harmonic fields which are generated when an alternating electric field is applied to a plasma are calculated. The plasma has a density gradient and is immersed in a uniform static magnetic field. The harmonics are very strongly excited near the upper hybrid frequency.
