Curtis Type Non-Inductive Resistors
No full textIn response to a need for increasing precision in alternating current research, researchers at the National Bureau of Standards (NBS) undertook an investigation into the behavior of resistance coils when subjected to alternating current voltage. Many commercial resistance coils performed well with direct currents, but could not measure alternating currents satisfactorily. Several NBS staff members were pioneers in developing special windings in which the turns were frequently reversed in direction to minimize inductance or capacitance in resistors used on alternating current. Later, manufacturers developed looms for weaving such resistors.
These two resistors, developed circa 1912 by Harvey L. Curtis of NBS and each of 1,000 ohms, were wound on a split cylindrical form so that the successive turns led the current around the form in opposite directions. The magnetic effects of the current were thus minimized, its inductance reduced to +30 microhenrys, while the difference of potential between adjacent turns, and hence the effective capacitance, was much smaller than in the more common bifilar winding.[H] 23 cm [W] 10.5 cm [L] 11.5 c
A deterministic algorithm for experimental design applied to tomographic and microseismic monitoring surveys
No full textMost general experimental design algorithms are either: (i) stochastic and hence give different designs each time they are run with finite computing power, or (ii) deterministic but converge to results that depend on an initial or reference design, taking little or no account of the range of all other possible designs. In this paper we introduce an approximation to standard measures of experimental design quality that enables a new algorithm to be used. The algorithm is simple, deterministic and the resulting experimental design is influenced by the full range of possible designs, thus addressing problems (i) and (ii) above. Although the designs produced are not guaranteed to be globally optimal, they significantly increase the magnitude of small eigenvalues in the model–data relationship (without requiring that these eigenvalues be calculated). This reduces the model uncertainties expected post-experiment. We illustrate the method on simple tomographic and microseismic location examples with varying degrees of seismic attenuation
