"Whether modeling the Hubble Space Telescope or the heart's left ventricle, we realize that all our projects have the potential to write history."

Dr. Michael C. Apostal
JAR Founder

No matter what the subject or the scope of a project -- from space to semiconductors, from aluminum cans to weapon systems -- no one has more experience, better technology or a stronger allegiance to a job well done.

JAR has been involved in literally hundreds of analysis and design projects over the past twenty years. The projects summarized below indicate the extensiveness of JAR's engineering experience.
