The luckiest thing in his life, however, would be seeing a notice to work at the Massachusetts Institute of Technology (MIT) with Vannevar Bush, then the dean of the engineering school, on the
differential analyzer, a large-scale analog computer--a mechanical brain.
After graduating from U-M, Shannon moved to the Massachusetts Institute of Technology (MIT) to work on the
Differential Analyzer, which at that time was the world's most renowned computer.
This was quickly followed by the world's first automated five-part
differential analyzer, the Technicon Hemalog-D, an instrument based on a combination of optical and cytochemical methods.
Vannevar Bush, vice-president of technology and dean of engineering, who under the Institute's program to eliminate delay and complications in engineering and research, has previously made important contributions to the mechanical solution of mathematical problems, including the famous
differential analyzer. The simultaneous linear algebraic equations solved by the new machine occur constantly over a wide range of engineering and scientific analyses.
The cell counter used for this study was a CELL-DYN 1700 which is a 3-part leukocytes
differential analyzer. The use of a 5-part leukocyte
differential analyzer would have been more beneficial for the verification of purity of neutrophils.
The Marshall
Differential Analyzer Team is a collection of undergraduate and graduate students gathered together with a common goal of studying and constructing a mechanical
differential analyzer, a machine designed and first built in the late 1920's to solve nonlinear differential equations that could not be solved by other methods.
As a reporter interested in computers, Zachary is eager to embrace Bush as one of the founding fathers of American computers, but he recognizes that Bush's analog machines, like the famous
differential analyzer of the thirties, belong to a different time and place.
Then in 1930 Vannevar Bush of MIT developed a
differential analyzer, a large analog computer.
The dialog generator receives a file of errors from the
differential analyzer, parses it into a user-presentable form, and displays it on the screen.
Withinday physiologic variation of leukocyte types in healthy subjects as assayed by two automated leukocyte
differential analyzers. Am J Clin Pathol.
According to Bowden, that year he "went to see Professor Douglas Hartree, who had built the first
differential analyzers in England and had more experience in using these very specialized computers than anyone else.
Pittman believes that recent advances in automated
differential analyzers that allow for quantitative IG reporting has resulted in the biggest net efficiency change in how his hematology laboratory functions.
