Design of an electrical analog for spherical wave propagation in solid elastic media

Creator:

Papageorge, George Elefterios

Abstract:

With the advent of underground testing, the study of the propagation of seismic signals has become of great importance. This thesis investigates the design of electrical analogs to represent the propagation of seismic waves. The analogs developed allow for the study of the effects of variations in the characteristic constants...

Effects of dispersion and parent population density on enclosed populations of Microtus montanus (Peale)

Creator:

Smith, Jerome Stafford

Abstract:

This field investigation was designed to further the understanding of the significant influence which parent population density, as well as dispersion, have on the dynamics of enclosed populations of the montane vole, Microtus montanus (Peale). The study was conducted in Klamath County, Oregon from June, 1963 to February, 1964. The...

A study of radar echo patterns related to mesoscale network observations and topography

Creator:

Knechtel, Kenneth Boyd

Abstract:

This investigation studies the relationship of the reflectivity in the radar beam depicted by the radar echo patterns to the computed reflectivity at surface observing stations under the radar beam. Drop size distributions at stations in the Oregon State University Mesometeorological Network during the storm period of 27-30 March 1963...

Masters Thesis
An introduction to scators

Creator:

Choban, Paul James

Abstract:

The indicated sum of a real scalar and a real or imaginary vector is called a scator. Either the scalar part or the vector part may be null. Scators generalize the complex variable to n-space. The algebra of scators is not generally associative under multiplication but the commutative and distributive...

Critical path scheduling : tableau method

Creator:

Inoue, Michael Shigeru

Abstract:

The concept of a Critical Path Scheduling Tableau is introduced as an integrating tool for solving industrial engineering problems involving the application of transitive graphs. The Tableau is a combination of a precedence matrix and a boundary time table which may be used to construct graphical representations for critical path...

Interrelationships between fungi associated with the damping-off disease of table beets in Oregon

Creator:

Lin, Shu-yen

Abstract:

Damping-off of table beets is of widespread occurrence in the Willamette Valley of Oregon. Pythium ultimum Trow., Pythium debaryanum Hess., and Rhizoctonia solani Kuhn. were found to be the important pathogenic fungi causing the disease. Trichoderma viride, Penicillium spp. Streptomyces spp. and certain isolates of bacteria, all saprophytic organisms associated...

The effects of balsam woolly aphid infestations on wood anatomy of true firs

Creator:

Doerksen, Allan Harold

Abstract:

Three species of true firs in the Pacific Northwest--Abies gran-dis, grand fir; A. amabilis, Pacific silver fir; and A. lasiocarpa, subalpine fir--are severely damaged or killed by an imported insect pest, the balsam woolly aphid (Chermes (Adelges) piceae Ratz.), Infestations of this insect cause abnormalities in the wood and, in...

Logarithmic generation by binary decoding

Creator:

Hill, James Carver

Abstract:

Instruments which combine the features of a digital-to-analog conversion and a linear-to-logarithmic scale change usually perform the digital-to-analog conversion first. These instruments are accurate to within five or ten percent over ranges of five or six decades. This thesis presents a method which uses combinatorial logic to perform the linear-to-logarithmic...

Investigation of twelve earthquakes off the Oregon and northern California coasts

Creator:

Rinehart, Verill Joanne

Abstract:

Twelve earthquakes off the Oregon and Northern California coasts were used in this research to study whether faulting associated with these quakes was of the San Andreas type as observed in California. The first motions of the incident P and S waves recorded at various seismic stations in the Pacific...
