Mechanical characterization and modeling of solder joints for the secondary side reflow of large IC packages

Creator:: Yutzie, James D.
Abstract:: As the drive continues to reduce the size of Printed Wiring Assemblies (PWAs), improve performance of electronic assemblies, and reduce costs of these products, reliable secondary (bottom) side reflow operations must be developed. Attaching Surface Mount Technology (SMT) components to the secondary side of a Printed Circuit Board (PCB) is...

Photogrammetric uses of a new-generation analytical stereoplotter in forestry

Creator:: Kiser, James D. (James Donald)
Abstract:: The development of personal computer software coupled to an analytical stereoplotter allows major gains in efficiency and accuracy in a number of forestry related subjects. This thesis describes the operation of a system developed by Carto Instruments. This thesis demonstrates how area estimates might be made in a systematic way...

Forest Successional and Disturbance Dynamics in the Southern Blue Mountains of Eastern Oregon

Creator:: Johnston, James D.
Abstract:: The application of modern land management practices beginning at the turn of the 20th century is widely believed to have dramatically transformed forest landscapes of the inland Pacific Northwest. Restoring historical conditions to make forests resilient to future climate and disturbance regimes is a major goal of federal forest managers....

Evaluating the effectiveness of illuminated and shadowed contour lines

Creator:: Eynard, James D.
Abstract:: Illuminated contour lines, where line width and color are varied based on an angle of illumination, date back to the mid-nineteenth century, but their effectiveness compared to conventional contour lines has not been fully examined. Currently, illuminated contour lines are not widely used in computer-based cartography because they are not...

A three-trophic-level perspective on factors influencing herbivore abundance on collard

Creator:: McIver, James D.
Abstract:: The influence of natural enemies and plant apparency in determining the abundance of the cabbage aphid Brevicoryne brassicae L. and the imported cabbageworm Pieris rapae L. was examined on collards grown in a collard monoculture and in a collard-alfalfa biculture. This design was used to examine the factors affecting collardherbivore...

The relationship of selected biomechanical components to the presence of swimmer's shoulder in experienced age-group swimmers

Creator:: Slear, James D.
Abstract:: Seventy-six competitive swimmers from eight swimming teams were surveyed about swimmer's shoulder symptoms over the past year, then were placed into symptomatic levels: nonsymptomatic and symptomatic with the symptomatic sample divided into moderately and highly symptomatc levels. Swimmers were videotaped to evaluate maximum body roll and the simultaneous angle of...

Distribution of Oligonychus (Oligonychus) ununguis (Jacobi) (Acari: Tetranychidae) and predator mite species (Acair: Phytoseiidae) on field-grown Douglas-fir (Pseudotsuga menziesii [Mirb] Franco) Christmas trees

Creator:: Calkin, James D.
Abstract:: The shake and wash technique (samples placed in a jar with alcohol added and shaken to remove the mites) was effective in removing 100% of the predator mites, and adult spruce spider mites from Douglas-fir foliage and 98% of the spruce spider mite nymphs. Eighty-eight percent of the spruce spider...

Filling a rough-mill cutting order using a fuzzy logic controller

Creator:: Anderson, James D.
Abstract:: Because of their high cost, reducing the number of boards used to fill an order of dimension parts is an important goal in a lumber rough mill. FLCO (Fuzzy Logic Cutting Order) is a computer program that achieves this goal. Using the concepts of fuzzy logic control, FLCO provides a...

Extensions for paired comparisons models

Creator:: Kolsky, James D.
Abstract:: The Thurstone-Mosteller and Bradley-Terry Models are commonly used to rank items from paired comparisons experiments in which one item in each pair "wins," and to assess the importance of time-independent explanatory variables on such rankings. The first part of this thesis clarifies the use of probit and logistic regression models...

Methods for short-term prediction of wind speeds in the Pacific Northwest Columbia Gorge wind farm region

Creator:: Davidson, James D.
Abstract:: Variable electrical generation (VG) sources such as wind farms are an increasing percentage of total electrical generation in the Bonneville Power Administration (BPA) balancing area and are starting to impact the ability of the regional balancing authority to control the electric grid. Wind farms are not dispatchable and challenge historical...
