Phil Brubaker

Phil Brubaker completed his BS from Oregon State University School of Mathematics. He is the owner of Optimal Designs Enterprise, a Calculus-level Software organization. He has been involved in industrial training on math modeling & optimization problems for over 35 years.

Phil has developed several applications (CurvFit, FC-Compiler, Match-n-freq, el at) to show how Calculus-level Problem-Solving can help users tweak parameters while minimizing their efforts; i.e. reduced development times by over 90%.

My first job was with Lockheed Aircraft Co. building the SR-71 (Black Bird). One assignment had me designing the pilot's suit. It was to be 1/4" thick consisting of 5 materials and required to drop the outside temperature from its high to 98 degrees next to the pilot's body temperature. A great math problem!

Another job was at Memorex Corp. designing a "Matched Filter" for a 14" disc drive. This electrical filter was to make a pulse more symmetric and thinner. The more symmetric and thinner a pulse, would help minimize the "Pattern-Induced-BitShift" (PIB). Heavy math problem! (Main LaPlace transform equation took me 22 pages of hand written notes to derive the necessary equations. Oh, those little minus signs kept giving me trouble!)

Next job was at Lockheed Missiles & Space Co. Here I had different assignments. One assignment had me analyzing, called Digital Signal Processing (DSP), a plume from a space craft to try and label it as a "Friend or Foe". If its a Friend no problem, but a Foe may require action to be taken else it may shoot you down. This job required understanding the Fourier Transform. (FFT algorithm was being used. That was a BIG mistake. I switched to 10 other algorithms and partially solved the problem.) For more, see my SpectrumSolvers v. 6 app.

After a lay-off in 1991, I started writing my math textbook. 26 years later the book is done plus a website, 4 apps developed, and a front-end for a compiler, I developed, in order to show a new computer language that makes solving math problems very easy... in minutes!
