Simple derivation of the thermal noise formula using window-limited Fourier transforms and other conundrums
A simple theoretical derivation for obtaining the Johnson thermal noise formula using window-limited Fourier transforms is presented in detail for the first time, utilizing the well-known energy theorems. In the literature, a diverse range of alternative methods already exist, and the pedagogical value of the Fourier transform approach illustrates useful mathematical principles, taught at the undergraduate level, naturally highlighting a number o…
Occupational physical activity and other risk factors for preterm birth among US Army primigravidas
We examined the relation of occupational physical activity to the risk of preterm birth among US Army active-duty primigravidas between 1981 and 1984 using 604 cases (preterm deliveries; less than or equal to 37 weeks gestation) and 6,070 controls (term and post-term deliveries). Women employed in the highest physical activity levels had increased odds of preterm delivery ranging from 1.69 to 1.75. The relation was not changed by adjustment for t…
Finding Initial Conditions in Electric Circuits
A novel way of finding the initial conditions in an electric circuit is described. The method is particularly suited to circuits in which the excitation contains step or impulse functions
