Forest species classifications are becoming increasingly automated as advances are made in machine learning. The algorithms used to identify tree species range from simple decision trees to intricate neural networks, and often excel in accurately delineating tree species. However, complex algorithms can have high input costs, including the cost of...
Public lands in the Pacific Northwest are managed for multiple uses including timber production, recreation and aesthetic value, maintaining wildlife habitat, conserving native species, and carbon storage. Wildfires impact large areas encompassing broad environmental conditions. Interactions among underlying environmental gradients and alteration of overstory competition by fire of varying severities...
The purpose of this investigation was to locate, organize and
analyze information pertaining to clothing and household textiles of
Aurora Colony, Oregon, which existed from 185 7 to 1877. Aurora
Colony was a communal group, headed by Dr. William Kiel, which
emigrated from Bethel, Missouri to Oregon in 1857. This...
On April 20th, 2010 the Deepwater Horizon drilling rig in the Gulf of Mexico malfunctioned leading to a 4.9 million barrel oil spill. The released oil affected marine life, coastal ecosystems, and the economic framework of the Gulf of Mexico. The Gulf spill spurred research on absorbent materials and engineering...
A survey of the major bodies of water, temporary and perennial,
in the region of Northern Utah revealed a limited distribution of
the Notostraca. Lepidurus (Linn.), the only representative
found, was restricted to a single temporary shallow lake. Dry Lake,
in the southern end of Cache County.
Dry Lake occupies...
A fully automated method for content-based color image retrieval is developed to extract color and shape content of an image. A color segmentation algorithm based on the k-mean clustering algorithm is used and a saturated distance is proposed to discriminate between two color points in the HSV color space. The...
