10 april 2020 I've consolidated all of my prior websites into www.sr-ix.com. All other domain names are obsolete and may disappear at any time. This site is search-engine and mobile-device friendly. Most of the AMC links remain the same except for the domain name. Much new work has been added.

This website started in 1993 as wps dot com, became world power systems dot com, work reorganized as sensitive research. The canonical name is www.sr-ix.com.
