To visualize vibrations in mechanical systems, e.g., machine tools, their movements are measured by means of suitable sensors. The signals from these sensors are processed and displayed as animated pictures on a computer screen. Accelerometers have been chosen as the most suitable sensors for this purpose. Their main advantages include...
This paper describes the concepts and operations of two programs, SLASH, which simulates forest-residue populations, and INTRSCT, which performs line intersect residue inventories on these populations. Program SLASH creates residue pieces on a 5.07 -acre square area to specified orientation and spatial distributions. The user can specify constant geometric piece...
In recent years, the forest products industry has been
forced to cope with a supply of raw material that is
declining in both quality and quantity. In addition, log
prices are escalating rapidly. Because log costs may
represent as much as 90 percent of the overall production
costs of lumber...
The goal of this phase of the study was to develop a model of the Tualatin River incorporating Scoggins Creek and Hagg Lake. This tool will be used in conjunction with a hydrologic model, the EPA HSPF model (Johnson, Imhoff, and Kittle, 1984), to analyze management strategies to improve water...
