Who Is This Weibullguy?

Weibull - continuous distribution of a random variable proposed by Wallodi Weibull. Guy - male of the human species.

Me - Electrical Engineer undergraduate, Statistics graduate, work as a Reliability/Safety Engineering Consultant (Yes, I am available. Please feel free to contact me). Previously worked as a Reliability/Safety Engineer in the aerospace, defense, nuclear, and automotive industries. Current interests include repairable systems analysis, Kijima Type I and Type II models, and system optimization under imperfect repair.

I analyze failure and repair data to estimate parameters of the distribution(s) describing system and component failure times. This is often refered to as Weibull analysis (although there are many other distributions used). Hence, Weibullguy. Now you know.

In response to a post I saw on one of the mailing lists, "I don't have a clue who all the devs at CBLFS are. They all use some stage-names." Here is my abbreviated resume, none of which actually qualifies me as a software developer. Consider that the grain of salt with which to take my entries.
