Factoring N = p r q for Large r [chapter]

Dan Boneh, Glenn Durfee, Nick Howgrave-Graham
1999 Lecture Notes in Computer Science  
Hence, we obtain a new class of integers that can be efficiently factored. When r ≈ √ log p the algorithm is asymptotically faster than the Elliptic Curve Method.  ...  We present an algorithm for factoring integers of the form N = p r q for large r. Such integers were previously proposed for various cryptographic applications.  ...  Acknowledgments We thank Paul Zimmermann, Peter Montgomery and Bob Silverman for supplying the running times for ECM, and Don Coppersmith for several useful conversations.  ...

Arbitrary Accuracy Integration Scheme for the Subsonic Doublet Lattice Method

Louw H. van Zyl
1998 Journal of Aircraft  
The approximation in the unsteady component places a restriction on the doublet lattice method in terms of box aspect ratio, which does not apply to the vortex lattice method.  ...  The downwash factors are calculated as the sum of the steady component, identical to that of the vortex lattice method, and an unsteady component.  ...
