Slow perturbations of the drop speed of a nearly freely falling, winged, microstructure probe in the upper
200 m at station P are interpreted as vertical velocity fluctuations of an internal wave field. The frequencies of these fluctuations lie in the 2.5- to 4-cph band, near the buoyancy-frequency cutoff. A...
It is possible to purchase, for as little as $10,000, a cluster of computers with the capability to rival the supercomputers of only a few years ago. Now, users that have little to no experience developing distributed applications or managing a cluster are in a position to do so. To...
Timber engineering is currently in the midst of a significant evolution due to the rise of mass timber products, like cross-laminated timber (CLT). Increasing numbers of structural engineers are facing the challenge of designing lateral-force-resisting systems (LFRS) for multistory CLT structures. LFRS solutions such as steel frames, concrete cores, or...
The objectives of this study were to: (1) determine if individual
differences in the learner characteristics of field dependence, state
and trait anxiety, age, sex, and prior computer experience were related
to performance in operating a computer system; (2) to determine if
differences in performance would occur as a result...
Several models now exist for predicting the dissipation rate of turbulent kinetic energy, ϵ, in the oceanic thermocline as a function of the large-scale properties of the internal gravity wave field. These models are based on the transfer of energy toward smaller vertical scales by wave-wave interactions, and their predictions...
This report is intended for citizen advocates. The goal is to provide a concise summary of current issues and problems for native salmonids in the Upper Deschutes and describe the actions needed to resolve those problems. It is based on information from all federal and Oregon agencies involved in the...
In this report we describe a preliminary version of a temperature/conductivity profiler that combines the calibration accuracy of a CTD with the vertical resolution of a microstructure instrument and the ease of deployment of an XBT. We also describe the results of a test of this version on a month-long...
Fishing firms in Oregon operate in a complex and dynamic physical, biological and institutional environment. Within this environment, managers of these firms will attempt to maximize some objective function which may include profit. This maximization is dependent upon the level of output, or the levels of inputs. Given a relationship...
This work examines the varied populations which have inhabited the South Fork region from prehistoric times to the present.
It disclosed that even though almost no archaeology has been done
in the area, data from contiguous regions suggest that persistent
and careful archaeological investigation should reveal valuable
and informative sites...
