Journal ArticleDOI
A thermodynamic treatment of Penfield's paradox in circuit theory
D.J. Epstein,Paul Penfield +1 more
TL;DR: In this article, it was shown that the paradox results because of the incorrect assumption that the noise current at the resistor terminals accounts for the total motor torque, which is incorrect because the circuit theory paradoxically suggests that a series motor connected to a noise resistor should run as a perpetual motion machine of the second kind.
Proceedings ArticleDOI
An APL interpreter written in APL
TL;DR: An APL interpreter has been written in APL that includes a set of interacting APL functions that accept quote-quad input and act on it in the same way as APL itself would.
Journal ArticleDOI
A resolution of Penfield's paradox
T.A. Goodwin,Paul Penfield +1 more
TL;DR: In this article, the theoretical possibility of using the thermal noise from a resistor to drive a motor with armature and field in series is discussed, and it is shown that the armature produces thermal noise, thereby establishing a mechanism for thermal equilibrium between the motor and the resistor.
Journal ArticleDOI
Proposed high-efficiency diode oscillator
TL;DR: High efficiency oscillator using avalanche square wave diode, considering case of silicon p-i-n diode was proposed in this paper, where it was shown that the diode can achieve high efficiency.
