Contributions to Collaborative Filtering Research

Creator:: Nong, Shuzhen
Abstract:: In this report, I first introduce three areas of interest to collaborative filtering researchers, namely: (a) how to solve the sparsity and scalability problems in recommendation systems; (b) how to rapidly develop and test collaborative filtering algorithms; and (c) how to apply collaborative filtering to unbounded numeric preference data. In...

Characterizing PM2.5 with Different Source Contributions

Creator:: Perez, Allison Mae S.
Abstract:: Ubiquitous fine particulate matter (PM2.5) exposures significantly impact global public health, yet little is known about the mechanisms causing these known adverse health effects. Oxidative stress due to PM2.5 associated chemical constituents, such as polycyclic aromatic hydrocarbons (PAHs), is a proposed possible mechanism for PM2.5 mediated health effects. Variations in...

College of Forestry Integrated Research Project : ecological and socioeconomic responses to alternative silvicultural treatments

Creator:: Maguire, Chris C., Chambers, Carol L., and Oregon State University. Forest Research Laboratory
Abstract:: The College of Forestry Integrated Research Project (CFIRP) is an on-going experiment in the eastern Coast Range foothills of western Oregon. Started in 1989, a team of scientists, resource managers, and students at Oregon State University designed and implemented silvicultural alternatives to clearcutting. These silvicultural practices aimed to create and...

Maximizing efficiency of forest herbicides in the Sierra Nevada and Oregon : research background and user guide

Creator:: Fredrickson, Edward and Newton, Michael, 1932-
Abstract:: This paper comprises two major sections. In the first, tests of the influence of several application factors on efficiency of silvicultural herbicides are described for evergreen shrub, deciduous shrub, and herbaceous forest vegetation in Oregon and California. The second presents decision trees illustrating how to use the experimental results and...

Wood pole maintenance manual

Creator:: Morrell, Jeffrey J. and Oregon State University. Forest Research Laboratory
Abstract:: The specification, inspection, and remedial treatment of utility poles are addressed. Included are discussions of enhancing specifications for improved performance, techniques for detecting decay and other defects, and chemical treatments available for arresting decay of poles in service.

Poplar chip production for Willamette Valley grass seed sites

Creator:: Withrow-Robinson, Bradford A., Hibbs, David E., Beuter, John H., and Oregon State University. Forest Research Laboratory
Abstract:: This publication is part of a 1-year project funded by the Oregon Department of Agriculture, Alternatives to Field Burning Program. Crop substitution is one strategy for reducing smoke from field burning. The objective of the project was to evaluate the potential for hybrid poplar as an alternative crop for poorly...

Production and costs of cut-to-length thinning : experience from the Willamette Young Stand Project

Creator:: Kellogg, L. D. (Loren D.), Spong, Ben, and Oregon State University. Forest Research Laboratory
Abstract:: Young Douglas-fir stands were commercially thinned to achieve vegetation- and wildlife-related objectives. Harvesting and forwarding production and costs were compared among three mechanized thinning treatments: light thin [(115 residual trees per acre (tpa)], light thin with 0.5-ac openings (92 residual tpa), and heavy thin (53 residual tpa). The sites were...

Habitat use by snag-associated species : a bibliography for species occurring in Oregon and Washington

Creator:: Weikel, Jennifer M., Hayes, John P. (John Parker), and Oregon State University. Forest Research Laboratory
Abstract:: Fifty-seven species of wildlife rely on or frequently use snags for breeding, roosting, or denning in Oregon and Washington. Several publications offer information on use of snags by wildlife, influence of management activities on snags and snag users, and approaches to managing snags to benefit wildlife. Because of the diverse...

Tractor thinning productivity and costs : experience from the Willamette Young Stand Project

Creator:: Kellogg, L. D. (Loren D.), Davis, Chad T. (Chad Thomas), and Oregon State University. Forest Research Laboratory
Abstract:: Harvesting productivity rates and costs were determined for three silvicultural treatments used in commercial ground-based thinning of young stands to achieve timber management objectives and enhance wildlife habitat. Treatment definitions were based on residual trees per acre (tpa) after thinning. The treatments were light thin (115 residual tpa), light thin...

"Waving Wand" Broadcast Hand Application of Herbicides: Technical Basis and Usage

Creator:: Newton, Michael, Cole, Elizabeth C., and Barry, Jack W.
Abstract:: The waving-wand system of broadcast chemical application implemented in swath widths to 40 ft (>12 m) is capable of simulating broadcast deposition patterns for herbicides similar to those delivered by helicopter. Drop sizes vary from center to edge of swaths, which can range from >1,000 to 5,000 microns (μ). Any...
