Abstract :
Slot effects in machines are analyzed using digital computations by means of punched-card techniques. Analysis methods are developed for ascertaining these effects in terms of large numbers of different machines so that optimum design combinations may be found. A general solution is indicated and a more practical solution using a simplifying assumption is developed in detail for use with punched-card computers. For qualitative results a still more approximate method is given in the Appendix.
