    • First-Order Cancellation Residue in Rectangular Memory Arrays 

      Buck, Dudley A. (MIT Digital Computer Laboratory, 1953-05-15)
      Aside from all second-order effects, there is an unwanted output voltage inherent in magnetic-memory arrays due to cores whose half-selected output voltages do not cancel. This voltage is due to two cores in the arrays ...
    • Group 63 Seminar on Magnetism, XLIV 

      Loeb, Arthur L.; Buck, Dudley A.; Menyuk, Norman (MIT Digital Computer Laboratory, 1953-03-26)
      This memo is a summary of a Group 63 seminar on magnetism. Topics include the Hartree and Hartree-Fock methods of arriving at a self-consistent field determination.
