Equations for predicting height to crown base for fourteen tree species in southwest Oregon

Creator:: Ritchie, Martin W., Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: Equations are presented for predicting height to crown base (or bole ratio) for fourteen species of trees common to the mixed-conifer zone of southwest Oregon. Nonlinear regression was used to fit a weighted logistic function for each species. The independent variables include height, crown competition factor in larger trees, stand...

A responsiveness metric for controllable characters

Creator:: Oregon State University. Dept. of Computer Science, Srinivasan, Madhusudhanan, and Metoyer, Ronald A., 1971-
Abstract:: This paper presents an empirical approach for measuring and characterizing the responsiveness of a character to changes in goal. Our approach is based on keeping track of the character's progress towards a frequently changing goal. A "distance-to-goal" function is defined to measure the progress. We then calculate an asymptotic proportion...

Approximation algorithms for solving cost observable Markov decision processes

Creator:: Oregon State University. Dept. of Computer Science and Bayer, Valentina
Abstract:: "The specifi c problem addressed in this proposal is the development of good approximation algorithms for solving problems that have partial observability. The model we propose associates costs with obtaining information about the current state. We want to predict when and how much it is necessary to observe. We want...

Native wetland, riparian, and upland plant communities and their biota in the Willamette Valley, Oregon

Creator:: Titus, John H., Christy, John A., VanderSchaaf, Dick, Kagan, James S., and Alverson, Edward R.
Abstract:: As part of the Willamette Basin Geographic Initiative Program, the Environmental Protection Agency (EPA) funded The Nature Conservancy of Oregon to inventory, classify, and map native wetland and riparian plant communities and their threatened biota in the Willamette Valley. Between October 1994 and September 1996, we evaluated 172 wetland and...

Ability of natural extracts to limit mold growth on Douglas-fir sapwood

Creator:: Maoz, Michal, Karchesy, Joseph J., and Morrell, Jeffrey J.
Abstract:: The ability of selected plant extracts from wood and foliage to inhibit mold regrowth on fungal colonized wood was evaluated on Douglas-fir sapwood. Most foliage extracts produced some inhibition of Graphium or Trichoderma species, but isolations of other fungi increased following treatment. Five out of eight wood extracts produced 50%...

Antifungal effects of hinokitiol and its sodium salt for wood protection

Creator:: Li, Shujun, Freitag, Camille M., Morrell, Jeffrey J., and Okabe, Toshihiro
Abstract:: The ability of natural and synthetic hinokitiol, as well as a water soluble derivative (hinokitiol sodium salt), to protect wood against fungal attack was examined. Synthetic and natural hinokitiol provided similar protection. All three materials exhibited similar antifungal activity against Aspergillus niger and Penicillium citrinum on yellow poplar wafers at...

Examination of moisture content variation within an operational wet deck

Creator:: Schimleck, Laurence, Love-Myers, Kim, Sanders, Joe, Raybon, Heath, Daniels, Richard, Andrews, Edward, and Schilling, Erik
Abstract:: 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...
