Many forest products companies in the southeastern United States store large volumes of round-wood under wet storage. Log quality depends on maintaining a high and constant wood moisture content; however, limited knowledge exists regarding moisture variation within individual logs, and within wet decks as a whole, making it impossible to...
Alternative silvicultural systems, such as group
selections, have recently come into vogue in the U.S.
Pacific Northwest in response to political and public
pressure against traditional, even-aged silviculture. There
is also interest in silvicultural systems for multiple
resources. Little is known about planning logistics,
operational requirements, and harvest costs for...
In the area surrounding Clarno, Oregon, pre-Cretaceous metamorphics, Cretaceous marine sediments, and a varied assemblage of Tertiary volcanic rocks are known. The oldest exposures are of an homogeneously fine-grained, mildly metamorphosed, limy shale to which the term "Muddy Ranch phyllite" is applied. Non-metamorphosed, Cretaceous marine shales and graywackes, approximately 1500...

Guidelines for using style to improve computer program comprehension
have often been proposed without empirical testing. This thesis reports on the
results of three controlled experiments that investigated ways program style may be
used to aid comprehension of source code listings.
Experiments 1 and 2 were conducted using advanced computer...
Recent developments in digital communications at microwave frequencies have revealed that local oscillator phase noise is often a factor in the bit error rate (BER) analysis. Digital signals transported across microwave radio links acquire waveform jitter from local oscillator phase noise. As jitter increases so does BER.
The main goals...
Employers often lament that many American workers are not qualified for present and future jobs due to changing skills requirements and deficiencies of schools. In 1991, the Secretary of Labor's Commission on Achieving Necessary Skills (SCANS) report recommended educators use work sites to help students achieve foundation skills and workplace...
This study was undertaken to evaluate the occurrence and characteristics of undercut streambanks in forested headwater streams of the Oregon Coast Range. Undercut streambanks and associated reach characteristics were surveyed along 46 sample reaches (each 152 m in length) in 8 streams; all sample reaches occurred in unmanaged forested riparian...
