An investigation of a criterion for the optimum transient response of servo-mechanisms
A new criterion for the optimum transient response or linear systems (in particular regulating systems) is discussed and investigated. The criterion is evaluated analytically for systems of the second and third order. ...
Effect of vibrations on the yield strength of a low carbon steel
Experimental results show that, when a specimen is subjected to vibration in the frequency range from 15 kc to 80 kc, the steady stress necessary to cause plastic deformation is appreciably reduced. This reduction is ...
An application of analog computer techniques to the problem of interpretation of the contact log
It is hoped that the following report may serve as the groundwork or basis for further applications of analog computer techniques to the field of electrical well logging interpretation. The author feels that this type of ...
Analysis of low temperature chromatographic separation of methane-propane mixtures with N-decane on celite
An outline of the history of chromatography is presented, reviewing briefly the existing theories. The theory of Jame sand Martin for gas liquid partition chromatography and the extension to their theory by Litlewood and ...
Heat transfer coefficients for Freon-12 condensing within a horizontal tube
The purpose of this investigation was to continue the study begun by Crosser (5) of heat transfer coefficients for condensing vapors in a horizontal tube. Condensing heat transfer coefficients for Freon-12 were measured ...
