| 41. | The approximation ignores the crimping round the equator of the bag.
|
| 42. | The pseudopotential approximation was first introduced by Hans Hellmann in 1934.
|
| 43. | The duoprisms therefore serve as good polytopic approximations of the duocylinder.
|
| 44. | There are similar methods that do not use the Born approximations.
|
| 45. | Ray transfer matrix analysis is one method that uses the approximation.
|
| 46. | You could maybe get some nice approximations by combining some filters.
|
| 47. | This approximation is only valid at relatively low V ds values.
|
| 48. | :Well, I managed to make a approximation of sine.
|
| 49. | However, this is really an artifact of the linear approximation.
|
| 50. | This model has an analytical solution in the Percus Yevick approximation.
