Abe, I'll need to read through a few papers before I understand the subject well enough to have a better sense of proportion about the many aspects of high-performance PDS design. I'm just getting started in this area ... got a lot to learn. As I stated in my note (with regards to the modelling I've done): I know that it is probably wrong and way off ... but I had to start somewhere. Thanks for your input and pointers. =============================== Martin Euredjian eCinema Systems, Inc. =============================== ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
