Competitive effects of overtopping vegetation on Douglas-fir morphology in the Oregon Coast Range

Creator:: Chan, Samuel S.
Abstract:: The response of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) saplings to various levels of brush overtopping when growing on three north-facing sites in the Oregon Coast Range was investigated for two consecutive years. A fisheye (hemispherical) photographic technique combined with a digitizing computer system was used to determine the percentage of...

Annual Mean Surface Heat Fluxes in the Tropical Pacific Ocean

Creator:: Weare, Bryan C., Strub, P. Ted, and Samuel, Michael D.
Abstract:: The four components of the long-term annual mean net surface heating of the tropical Pacific Ocean between 30°N and 40°S are calculated and portrayed. These flux elements were derived by using the bulk formulas and about 5 million marine weather reports for the years 1957–76. In addition to illustrating the...

A revision of the black grass bug genus Irbisia Reuter (Heteroptera:Miridae)

Creator:: Schwartz, Michael David
Abstract:: The black grass bug genus Irbisia Reuter was revised. Over 18,000 specimens were examined and information concerning the biology, host plant and distributional relationships of the species was compiled. In addition to external characters, the male claspers and vesica, and the female dorsal libiate plate of the bursa copulatrix and...

First-year response of Douglas-fir after release from snowbrush ceanothus

Creator:: Petersen, Terry D.
Abstract:: The release of Douglas-fir from competition with snowbrush (Ceanothus velutinus Dougl.) has often been suggested as a way to improve conifer yield in the western Cascades. This study investigated this possibility by describing changes in the availability of water and light and the response of Douglas-fir to the changing environment,...

Foraging ecology of pollinators in the early stages of secondary succession in the western hemlock (Tsuga heteropohylla (Raf.) Sarg.) zone of the Oregon Coast Range

Creator:: Burikam, Intawat
Abstract:: The early stages of secondary succession of the McDonald and Paul Dunn State Forests, Corvallis, Oregon, were grouped into three stages; herb, herb-shrub, and shrub, based on vegetation types. Flowers of herbaceous species and residual shrubs dominated in the early years after clear-cutting. Woody plants became increasing abundant in the...

An on-line advanced plant simulator (OLAPS)

Creator:: Samuels, Jeffery W.
Abstract:: A PC based on-line advanced plant simulator (OLAPS) for high quality simulations of Portland General Electric's Trojan Nuclear Facility is presented. OLAPS is designed to simulate the thermal-hydraulics of the primary system including core, steam generators, pumps, piping and pressurizer. The simulations are based on a five equation model that...

A general linear optimization algorithm based upon labeling and factorizing of basic paths on RPM network

Creator:: Stavrakis, George D.
Abstract:: A new method is developed for solving linear optimization problems based on the RPM network modeling technique which represents the primal and the corresponding dual models simultaneously upon a single graph. The network structure is used to eliminate the need for explicit logical variables and to provide a graphic tool...

SIDUR--a formalism for structuring knowledge bases

Creator:: Kogan, Dan D.
Abstract:: A new class of information intensive applications is emerging [Fuch82; Ohsu82] for which neither Artificial Intelligence (AI) nor Database technologies alone are well suited. Database systems do not provide the general inferential capabilities required for problem solving, while AI techniques have not been adapted to handle massive amounts of structured...

Acceleration of a heuristic PLA product term reduction program through complementation of the PLA specification

Creator:: Gilbert, John D.
Abstract:: Minimizing the number of product terms in a PLA implementation is a large step towards saving area on a VLSI chip using PLA logic. Due to the large amounts of computer time necessary to achieve this minimization, a number of heuristic approaches have been developed to provide near-optimal solutions in...
