The operation of a tunnel-diode delay-line memory cell is
examined in some detail, and a digital computer program which
approximately simulates the operation of this memory cell is developed.
The data from the computer simulation is compared with the
available experimental data and found to agree very closely for clock...
This thesis studies the question of unique factorization in
quadratic integral domains. In the first chapter many general
theorems and definitions from algebraic number theory are introduced.
The second chapter considers an integral domain in which
unique factorization holds. The necessary theorems to prove
unique factorization are developed. The third...
Swiss needle cast (SNC), an important fungal disease of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), has increased in severity throughout its natural and introduced range over the last half century. The role of climate change and forest management practices in the increase is unclear. We analyzed tree-ring chronologies from six late-successional...
Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) growth in the Pacific Northwest is affected by climatic, edaphic factors and Swiss needle cast (SNC) disease. We examine Douglas-fir growth responses to temperature, dew point deficit (DPD), soil moisture, and SNC using time series intervention analysis of intra-annual tree-ring width data collected...
