Banana-Doughnut. SH diff & other special cases With Shu-huei
"Banana-Doughnut. SH diff& other special cases With Shu–Huei" is mostly composed of original handwritten notes from Dahlen. The notes themselves are contained within a light blue loose leaf binder. This work began in January of 2000. Shu-Huei, the person mentioned on the title, was a post-doc whom Dahlen advised. A link to her current page can be found here. The majority of these notes comprise of Dahlen's mental wrestling with ray theory for seismic waves, particularly dealing with SH-waves, a subset of shear waves generated by seismic activity. Much of this interest was brought on by the work of Aki & Richards, who he mentions at numerous points in the notes. By the end Dahlen explores Airy functions and their potential computational use when applied to code. This collection can be found at: Guyot Hall, Princeton, NJ, 08540. Back to Main Page
