The use of mobile bar code scanners is expanding to markets beyond popular manufacturing uses, such as healthcare, environmental testing and professional services. The successful interaction of users with mobile bar code scanners is of great importance from a business and technology perspective as well as from the user standpoint....
The Pacific Coast form of Douglas-fir in natural forest succession
is an intermediate species thriving in the Coast Range and
Cascade Mountains of the Pacific Northwest. This species constitutes
26 percent of the standing timber in the United States, and 24 percent
of the nation's annual timber harvest. Characteristics of...
Sea level and current data collected near Newport, Oregon are
compared to determine an empirical relationship from which the low
frequency (f < .1 cpd) alongshore current field over the continental
shelf is estimated from observed sea level measurements at the coast.
Regression analysis of the near-surface (20-25 m) currents...
Arizona has experienced tremendous growth in the last several decades, typically
characterized by sprawling suburban, polycentric or edge city development. Unchecked growth or
"sprawl" has generated intense debate amongst various interest groups and has emerged as a
major political issue in Arizona. This paper employs a dualistic approach to land...
The viability of using ohmic "resistance" heating as a process alternative to
inactivating the heat-stable softening enzyme in Pacific whiting surimi was
investigated. A fast heating rate through the enzyme-active temperature range
would reduce the damage to the gelling network in surimi-based products.
Simulating the ohmic heating process in surimi...
Water source heat pumps are increasingly being used for residential
and commercial space heating. Typically, these heat pumps are capable
of both heating and cooling, and historically the design emphasis
has been on improving the units' cooling performance. Recently,
there has been more interest in improving the heating performance,
however,...
Coral reef ecosystems are the oceanic equivalent of tropical rainforests, in terms of biodiversity. The estimated 1,037,000 square kilometers worldwide of reef provide
habitat for over one million species of plants and animals (Hinrichsen, 1997). Coral reefs are important to the economy of coastal nations because of the fisheries and...
Oregon Department of Transportation (ODOT) Fleet Services manages a fleet that in 2008 included approximately 5,000 pieces of active equipment worth $340–$390 million. Every biennium, a fixed budget is available to replace a certain amount of this equipment. This research evaluated various measures for establishing equipment replacement priorities.
A model...
