Predicting and quantifying recreation and harvesting interaction with a geographic information system

Creator:: Boyd, David W.
Abstract:: This paper documents a study of the potential for using Arc View, a GIS software program, to evaluate possible interactions between timber harvesting impacts and recreational uses of adjacent forest roads and trails. Data on hiking, biking and horse riding was used to define recreational uses on specific trails. Harvesting...

Current-feedthrough cancellation technique for current-mode T/H circuits

Creator:: Young, David Y. W.
Abstract:: In this paper, an analysis of the clock-feedthrough effects in switched-current (SI)' circuits will be presented. The clock-feedthrough effects caused by the non-ideal characteristic of MOS switches when they are turned off limit the accuracy of the analog track-and-hold (T/H) circuits. A model to analyze and characterize this effect is...

Breeding habitat of harlequin ducks in Prince William Sound, Alaska

Creator:: Crowley, David W.
Abstract:: Breeding habitat of Harlequin ducks (Histrionicus histrionicus) was studied in eastern Prince William Sound, Alaska, during 1991 - 1993. Streams in Prince William Sound were surveyed for Harlequin ducks and monitored with mist nets. Physical characteristics of 24 Harlequin breeding streams were compared to those of 24 streams not used...

Digital clocks based upon dual side band suppressed carrier modulation

Creator:: Arnett, David W.
Abstract:: A method and apparatus are presented for generating suppressed carrier digital clock signals. These clock signals have the advantage of being broad band in nature and thus exhibiting lower power spectral density. Structures or systems utilizing such clock signals would be less likely to create electromagnetic noise of sufficient intensity...

Subsurface structural evolution along the northern Whittier fault zone of the eastern Los Angeles basin, Southern California

Creator:: Herzog, David W.
Abstract:: The Whittier fault forms the central part of a fault system extending from the East Montebello fault at Whittier Narrows to the Elsinore fault, which is traced as far as the Mexican border. The Whittier fault forms a restraining bend in this fault system, resulting in uplift of the Puente...

Conformational transitions of nucleosome core particles monitored with time-resolved fluorescence spectroscopy

Creator:: Brown, D. W. (David W.), 1937-
Abstract:: Time-resolved fluorescence spectroscopy was used to monitor the effects of varying ionic strength on nucleosome core particle structure. Two main methods were used in these studies. First, the fluorescence anisotropy decay of bound ethidium was measured and was shown to reflect the rotational tumbling of the core particle through solution,...

Evaluation of individual-tree and disaggregative prediction methods for Douglas-fir stands in western Oregon

Creator:: Ritchie, Martin W. and Hann, David W.
Abstract:: The efficiency of six disaggregative methods and two individual-tree methods was evaluated in terms of their ability to predict 5-year basal area increment for Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands in western Oregon. Models were developed for predicting gross stand basal-area increment and individual-tree diameter increment. In addition, models were...

Regeneration of salal : seedling establishment and the effects of overstory stand density on clonal morphology and expansion

Creator:: Huffman, David W. (William), 1962-
Abstract:: Regeneration of salal (Gaultheria shallon Pursh.) in the Coast Range of western Oregon was examined over two growing seasons in a three part study consisting of seedling establishment, clone excavation, and population sampling experiments. The effects of study site location, overstory stand density, and substrate on seedling emergence and survival...

Predicting height for undamaged and damaged trees in southwest Oregon

Creator:: Hanus, Mark L., Hann, David W., and Marshall, David D.
Abstract:: Equations for predicting tree height as a function of diameter outside bark at breast height are presented for various tree species common to southwest Oregon. Data for damaged and undamaged trees were analyzed with weighted nonlinear regression techniques. The effects of specific damaging agents and their severity on the height-diameter...
