In this thesis some applications of algebraic topology
are given. Kirchhoff's circuit laws are translated into the
language of algebraic topology: If G is the graph of
a network N, if i is a current distribution and if v is
a voltage distribution of N, then the two Kirchhoff laws...
Observations between 20 and 40 m depth were made with a towed thermostor
chain in the North Pacific. Despite the rapid vertical variation
of buoyancy frequency, spectra of isotherm displacements are in fair
agreement with other observations and with the Garrett-Munk model. The
spectra show evidence of a shoulder and...
The Washougal Mining District is located on the western flanks of the southern Cascade Range of Washington, approximately 50 km (30 miles) northeast of Vancouver, Washington. The district has produced only $573 since 1903, derived from copper and silver. The presence of hydrothermal mineralization and breccia pipes similar to those...
Allowable stresses in compression perpendicular to the grain (C-perp) have been too conservative for most structural uses. This study develops stress data for deformations beyond the proportional limit (PL), up to 0.1 inch for hem-fir. Fifteen boards from four western states were cut into small specimens representing three ring angle...
The effectiveness of sapwood basal area as an estimator of individual
tree basal area growth was tested on several young, even-aged
Douglas-fir stands, stocked at varying densities. For all densities,
ranging from partially open-grown to very overstocked stands, the
null hypothesis that there was no association between sapwood basal
area...
