First publication of Shannon's paper on how a Boolean function can be represented by the sum of two sub-functions of the original. The function was later named Shannon's Expansion or the Shannon Decomposition. ""The area of switching circuits design and optimization was a focus of considerable attention. Boolean algebra provided the basic mathematical foundation for switching circuit design. Shannon provided a basis for the The Synthesis of Two-Terminal Switching Circuits in 1949"". (Ashar, Sequential logic synthesis, 1992, p. 1).Claude Shannon is widely regarded as being the father of information theory and cryptography. Other papers contained in the present issue:1. Albersheim, W.J.Propagation of TE01 Waves in Curved Wave Guides. Pp. 1-32.2. Pierce, J.R." Hebenstreit, W.B. A New Type of High-Frequency Amplifier. Pp. 33-51.3. Hollenberg, A.V.Experimental Observation of Amplification by Interaction Between Two Electron Streams. Pp. 52-58.4. Robertson, Sloan D. A Method of Measuring Phase at Microwave Frequencies. Pp. 99-103.5. Rice, S.O.Reflection from Corners in Rectangular Wave Guides - Conformal Transformation. Pp. 104-135.6. Rice, S.O.A Set of Second-Order Differential Equations Accociated with Reflections in Rectangular Wave Guides - Application to Guide Connected to Horn. Pp. 136-156.
