The driving point mobility matrix of a machinery seating structure determines how much structural acoustic power is transmitted by the force vector that is applied at each machine mount. In the current research programme analytical estimation procedures have been developed for the mobility components that have a more extended validity than those based upon the ”thin beam” or ”thin plate” assumption. These expressions are summarized, discussed and compared with the results of numerical integration of the equations of the two- or three-dimensional theory of elasticity. They are validated against experimental results. A good agreement has been found between predictions and the results of the validation experiments. ne estimation procedures have shown to be sufficiently accurate for preliminary design studies. The results of numerical integration show an excellent agreement with the experimental results, so this approach can be chosen confidently when more precise results are required, on the basis of a further developed design.

L.; Bowers, D.; Sep. 1999; 76p; In English; Original contains color illustrations Report No.(s): PB2000-105972; FSGTR-PNW-446; No Copyright; Avail: CASI; A05, Hardcopy; A01, Microfiche This guide reports visual and descriptive documentation of ozone injury symptoms for common tree, shrub, and herbaceous species in the region. Symptoms observed in leaves of these species include chlorotic mottle, pigmented stipple, necrosis, and premature senescence, with considerable variation among and within species. Resource managers and scientists can use the photodocumentation in this guide to identify potential injury to plants in the field, and to distinguish ozone injury from other pathological conditions.

One algorithm uses radiative transfer and successive least squares fitting to find spectral shapes first for atmospheric dust, then for water-ice aerosols, and then, finally, for surface emissivity. A second independent algorithm uses a combination of factor analysis, target transformation, and deconvolution to simultaneously find dust, water ice, and surface emissivity spectral shapes. Both algorithms have been applied to TES spectra, and both find very similar atmospheric and surface spectral shapes. For TES spectra taken during aerobraking and science phasing periods in nadir-geometry these two algorithms give meaningful and usable surface emissivity spectra that can be used for mineralogical identification.

L.; Jan. 2000; 94p; In English Report No.(s): PB2000-101970; EPA/600/R-99/110; No Copyright; Avail: National Technical Information Service (NTIS) Four topics were studied concerning the modeling of groundwater flow in coastal aquifers with analytic elements: (1) practical experience was obtained by constructing a groundwater model of the shallow aquifers below the Delmarva Peninsula USA using the commercial program MVAEM; (2) a significant increase in performance was obtained by implementing the theory for variable density flow in a computer program that ran on a supercomputer using vectorization; (3) a new representation for the density variation was developed that can simulate the change from brackish to fresh water more accurately; and (4) it was shown
that for a specific example of a bell-shaped transition zone a Dupuit model gives accurate results unless the bell-shape is too narrow compared to the thickness of the aquifer.

The main workshop is divided into three smaller workshops, and each workshop has a volume as follows: (1) Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) Workshop; (2) Airborne Synthetic Aperture Radar (AIRSAR) Workshop; and (3) Thermal Infrared Multispectral Scanner (TIMS) Workshop. This Volume 1 publication contains 58 papers taken from the AVIRIS workshop.

Improvements made with the funding from this project have helped to strengthen the research efforts within both units, fostered graduate research training, and helped fortify partnerships with government and industry. With this funding, we were able to expand our computational environment in which computer resources, software, and data sets are shared by ICESS/Bren School faculty researchers in all areas of Earth system science. All of the graduate and undergraduate students associated with the Donald Bren School of Environmental Science and Management and the Institute for Computational Earth System Science have benefited from the infrastructure upgrades accomplished by this project. Additionally, the upgrades fostered a significant number of research projects (attached is a list of the projects that benefited from the upgrades). As originally proposed, funding for this project provided the following infrastructure upgrades: 1) a modem file management system capable of interoperating UNIX and NT file systems that can scale to 6.7 TB, 2) a Qualstar 40-slot tape library with two AIT tape drives and Legato Networker backup/archive software, 3) previously unavailable import/export capability for data sets on Zip, Jaz, DAT, 8mm, CD, and DLT media in addition to a 622Mb/s Internet 2 connection, 4) network switches capable of 100 Mbps to 128 desktop workstations, 5) Portable Batch System (PBS) computational task scheduler, and vi) two Compaq/Digital Alpha XP1000 compute servers each with 1.5 GB of RAM along with an SGI Origin 2000 (purchased partially using funds from this project along with funding from various other sources) to be used for very large computations, as required for simulation of mesoscale meteorology or climate.
