I read a few months back that a professor at some university in Europe had done extensive research on the polygraph and had posted his grievous findings about the unreliability of the polygraph on his university's web site. A company in Israel that makes lie detectors threatened to sue the university whereupon the university turned tail and ran. Does anyone know if there is a copy of this university's report that can still be accessed to read. Thanks.

I think what you are looking for is a study on Voice Stress.. a copy or link is somewhere on this site.  there are other studies on voice stress posted on other web sites. None verifiy the reliability of the process

Indeed, the study in question ("Charlatanry in forensic speech science: A problem to be taken seriously" by Anders Eriksson and Francisco Lacerda) is about voice stress analysis and takes a close look at Nemesysco's "Layered Voice Analysis." It may be read on-line here:
