Optical sensing technologies are pivotal in the manufacturing process, specifically in defect detection, tool condition estimation, and monitoring. The research aims to enhance the accuracy, efficiency, and reliability of manufacturing metrology by employing optical sensing technologies, such as laser profilometers and image processing techniques. The dissertation proposes intelligent and flexible...
Pine Creek Conservation Area (PCCA), just northeast of the John Day River in Wheeler County, Oregon, was acquired in 1999-2001 by the Confederate Tribes of Warm Springs with support from the Bonneville Power Administration (BPA), to mitigate for wildlife losses created by the large, hydropower Columbia River Dams, particularly the...
Fungal mitospores may function as dispersal units and/ or spermatia, and thus play a role in
distribution and/or mating of species that produce them. Mitospore production in
ectomycorrhizal (EcM) Pezizales is rarely reported, but here we document mitospore production
by a high diversity of EcM Pezizales on three continents, in...
Vegetation structure quantified by light detection and ranging (LiDAR) can improve understanding of wildlife occupancy and species-richness patterns. However, there is often a time lag between the collection of LiDAR data and wildlife data. We investigated whether a time lag between the LiDAR acquisition and field-data acquisition affected mapped wildlife...
In western conifer-dominated forests where the abundance of old-growth stands is decreasing, species
such as the Brown Creeper (Certhia americana) may be useful as indicator species for monitoring the health
of old-growth systems because they are strongly associated with habitat characteristics associated with old growth
and are especially sensitive to...
Using remotely-sensed metrics to identify regions containing high animal diversity and/or specific animal species or guilds can help prioritize forest management and conservation objectives across actively managed landscapes. We predicted avian species richness in two mixed conifer forests, Moscow Mountain and Slate Creek, containing different management contexts and located in...
The status of fisheries resources on coastal and offshore areas is getting worse in Taiwan. Thus, to establish a fishery resources management system has become the main task among stakeholders. In this study, we would like to examine the feasibility of imposing the community-based co-management system and setting closed fishing...
In this paper, we present the design, fabrication and characterization of a traveling
wave directional coupler modulator based on electro-optic polymer, which is able to provide
both high linearity and broad bandwidth. The high linearity is realized by introducing Δβ-reversal technique in the two-domain directional coupler. A travelling wave electrode...
Global increases in ultraviolet-B radiation (UVBR) have the potential to alter marine primary production and to affect carbon cycles and marine trophic dynamics. Estimates of UVBR induced photoinhibition have varied greatly, indicating that a common dose-response by marine phytoplankton may not occur from place to place. An action spectrum describing...
