Basic research on semantic interoperability is just beginning to address support for spatial data and information. This is clearly important for data portals containing geographic information system (GIS) layers, as well as supplemental information, often with cartographic and decision support tools. Agreements on content/semantic interoperability of these resources can help...
In this project, we have investigated three different techniques for plagiarism detection and have compared its effectiveness against that of an unaided human grader. The techniques investigated were word frequency analysis, sentence inclusion analysis and sub string inclusion analysis. We found that a combination of word frequency analysis and sub...
The project aims at building an application that would simulate a transparency that can either be overlaid on top of the graphical display of another application or used as a stand-alone by accepting input from a keyboard or a mouse to enhance a presentation. The project provides an environment to...
Development of variable speed horizontal axis wind turbines has resulted in a need for an analysis code with a rotor speed degree-of-freedom. This study develops a five degree-of-freedom time domain computer code that evaluates blade and rotor, mean and cyclic loads with nonlinear aerodynamics together with atmospheric turbulence as a...
Western juniper (Juniperus occidentalis) encroachment has been associated with increased soil loss and reduced infiltration resulting in the loss of native herbaceous plant communities and the bird and animal species that rely on them. Hydrologically, however, change in water yield has been linked with the amount of annual precipitation a...
An important element in rector safety and fuel performance assessments is the efficient calculation of the time dependent temperature profiles within reactor fuel pins. Because the fuel pins have temperature dependent thermal properties, the governing partial differential equations are nonlinear. Traditionally, finite difference or finite element methods have been used...
Research was conducted at the Starkey Experimental Forest and
Range in northeastern Oregon to determine cattle performance, diet
quality, botanical composition of forage ingested, and production
and utilization among rest-rotation, season-long, and deferred
rotation grazing systems. The grazing season lasted from June 20 to
October 10 of each year. Cows...
The accessions used to create the Snap Bean Diversity Panel (SnAP) were 378 snap bean cultivars and germplasm lines selected from North American and European germplasm. This panel supplements the 150 member Bean CAP snap bean diversity panel (SBDP) with an additional 228 snap bean accessions. The Bean CAP SBDP...
Amyotrophic lateral sclerosis (ALS) is a devastating disease characterized by the progressive degeneration of motor neurons. Dominantly-inherited mutations to the antioxidant enzyme Cu,Zn superoxide dismutase (SOD1) cause 3-6% of all ALS cases. The complete mechanism behind the toxicity of mutant SOD1 remains unclear, although significant evidence points to aberrant or...
A dynamic propagation of a finite crack of opening
mode in a micropolar elastic solid was investigated.
By using an integral transform method, a pair of twodimensional
singular integral equations governing
stress and couple stress was formulated in terms of the
displacement transverse to the crack, macro- and microrotations,
and...
Lasting, effective solutions to nitrogen (N) loss from container nurseries must
address layers of complexity ranging in scale from whole system nursery management
to gene expression. Group-based On-site Active Learning (GOAL) was developed to
aid nursery managers and related stakeholders (e.g. neighbors, policy makers,
regulating agencies, researchers) in developing a...
The effects of ¹⁵N-labeled fertilizer applied to mature summer-bearing red raspberry (Rubus idaeus L.) plants were measured over two years. Four nitrogen (N) treatments were applied singularly at 0, 40, or 80 kg·ha⁻¹ of N in early spring (budbreak), or split with 40 kg·ha⁻¹ of N (unlabeled) applied at budbreak...
Studies addressed impacts of planting dates and variable N applications on numbers
and size of Russet Burbank stems and stolon nodal position in relation to tuber growth and levels of hollow heart (HH) and brown center (BC). Low preplant N regimes produced larger tubers and final yields, and less HH...
Edge effects resulting from forest fragmentation are likely to alter the distributions and
interactions of resident species. I evaluated changes in species composition, species
turnover, and relative abundance of ground arthropods across replicated transects
extending from regenerating clearcuts into old-growth Douglas-fir forests. Arthropods
were collected from 3-August to 14-September in...
In order to aid comparison of estimates of genetic parameters between dominant and codominant makers for population genetics society, we developed a genetic dominance simulation program to determine how the dominance and biallelism could affect the estimation of population genetic statistics. The simulation indicates that genetic diversities within populations based...
The goal of this project was to investigate the addition of parameterized types to the Java programming language. Two different parametric polymorphism mechanisms were developed and compared. The first was a preprocessor and the second was a compiler.
Parameterized types allow a programmer to create generic programs. Much as a...
Cryptographic systems are used for secure communications in the government, in industry, and by individuals. Many cryptographic systems base their security on our inability to factor quickly. For this reason, in the last few decades several fast factoring algorithms have been developed. The Quadratic Sieve is one of the best...
Remote Event Listener(REL) is designed to glue remote events and remote listeners dynamically, and dispatch remote events efficiently and transparently
for distributed object-oriented systems. Components can be independently developed and remotely interconnected with REL, and software reusability can
be improved. Remote Event Listener along with Remote Method Invocation
makes distributed...
