(a)

Rewrite to emphasize the links to the Icon Legend, and definitions of Electronic College, and header. Put the links at the end of sentences.

A document is an important concept in our Electronic College, because when you do a library search you get a listing of all documents that meet your criteria. Next to each document name is an icon, indicating what kind of document it is. See the Icon Legend for a complete explanation of the icons. When you click an icon, a header appears, providing the document’s title, author, publication, topics, and, in most cases, an abstract. Following the header, the actual document usually appears below, although, in some cases, the header is all that we are able to provide at this time, due to circumstances.

(b)

Rewrite to create and emphasize links to the relevant images, appearing on the same page as the text.

We have been testing Absorbing Boundary Conditions (ABCs). The first image, below and to the left, shows the impulse response without any ABC, as captured by the Salvo software. We see the boundary and an even stronger secondary reflection from the boundary. This secondary reflection is due to a cross-correlation between the source wave reflection from the boundary and the primary arrival of the receiver wave. In the second image, below and in the middle, made with Clayton and Enguist’s ABC, the primary reflection has been removed, but the secondary reflection is still present, though weaker in strength. Finally, over on the right below, we have the impulse response using Liyang Xu’s ABCs, which use optimized coefficients to reduce reflected energy even more.
