An information processing model of the problem-solving
performance of mechanical designers is presented for four design
tasks: conceptual assembly design, layout component design, detail
component design, and catalog selection. These tasks are organized
into six kinds of segments called episodes, which describe the goal
structure of the designer while performing...
There is substantial interest in the application of mindfulness in counseling and psychotherapy. The appeal of mindfulness training and mindfulness-based interventions has increased as research continues to demonstrate benefits. Mindfulness practice has not only been effective in clinical applications with clients, but has also been conceptualized as beneficial for counselors...
A growth model is developed for coho salmon which accounts for
temperatures and feeding rates typically encountered in fish hatchery
operation. Feeding rates utilized by the model ranged from
maintenance to maximum utilizable rations. The model is derived from
an empirical equation for maximum growth rate, and a theoretical
equation...
The engineering design process and the advancement of future computer-aided-design systems need new design aids to be used during the conceptual design phase. This design phase is where information gathering and understanding of the problem are developed, analyzed and broken into small more manageable elements. These elements consist of customer...
Climate model simulations and paleoclimate proxies are two tools that enable an understanding of the climate history of the Earth. When utilized together, they form a powerful paradigm for understanding past changes. Proxies are the only physical link to the past conditions on Earth, and models “fill in the gaps”...
In current practice, design documentation often fails
to support the activities of design understanding,
communication, and redesign. A Design History Tool has been
developed to improve current design documentation. This
tool is a computerized design history that represents and
plays back important information generated during the
process of designing a...
A system which allows the computer to capture sketches
made by a mechanical designer is described. The system not
only recognizes basic features as they are sketched, but it
also reasons the spatial relationships between features and
builds a high level abstract representation (feature model)
of the artifact. The temporal...
An Engineering Decision Support System, EDSS, was developed using Bayesian mathematics which incorporates knowledge and confidence components observed in alternative-criterion pair decision making. The separation of knowledge and confidence has been previously unaccounted for in decision-making methods. EDSS provides decision support to individuals or teams which must make choices between...
Salmonid run sizes are strongly affected by their early marine stage. Fully understanding the life history of salmonids means understanding how they interact with their marine environment and with other fishes. Changes in the biological and physical environment off the Columbia River region affects the distribution and abundance of predatory...
An investigation of Mn uptake by five-day-old excised barley
roots revealed that a metabolically-mediated process was involved.
In short-term experiments, the rate of Mn absorption was comparable
to that of the macronutrient cations. Like other metabolically
absorbed cations, the Mn absorption rate was a direct function of
the ambient concentration...
