High Order Finite Elements SN Transport in X-Y Geometry on Meshes with Curved Surfaces in the Thick Diffusion Limit

Creator:: Woods, Douglas N.
Abstract:: The high-order finite element S[subscript N] transport equations are solved on several test problems to investigate the behavior of the discretization method on meshes with curved edges in X-Y geometry. Simpler problems ensured the correct implementation of MFEM, the general fi nite element library employed. A convergence study using the...

Discrete Ordinates Radiation Transport using High-Order Finite Element Spatial Discretizations on Meshes with Curved Surfaces

Creator:: Woods, Douglas N.
Abstract:: We spatially discretize the Sn transport equation using the high-order (HO) discontinuous finite element method (DFEM) on HO meshes. Previous work provided a proof-of-concept for this spatial discretization method in X-Y geometry. Included in the present work, we derive a spatial discretization for the Sn transport equation in both X-Y...

Image pre-processing algorithms for isolation of defects in Douglas-fir veneer

Creator:: Forrer, Johannes Barry
Abstract:: The goal of this research is to develop automatic techniques for identifying defects in Douglas-fir veneer. To achieve this goal, computer vision techniques, in particular image-processing, will be applied. Several pre-processing steps may be required to enhance images in making further analysis easier, faster, and more reliable. Pre-processing is often...

Log breakdown using dynamic programming and 3-D log shape

Creator:: Zeng, Yimin
Abstract:: A log breakdown model, SAW3D, was developed to optimize lumber recovery from logs of any shape in 3- dimensional space. The program uses a polygonal cross section representation of logs; three nested dynamic programming (DP) algorithms to optimize log breakdown, flitch and cant edging, and trimming operations; and a simple...

New methods for finite field arithmetic

Creator:: Yanik, Tuğrul
Abstract:: We describe novel methods for obtaining fast software implementations of the arithmetic operations in the finite field GF(p) and GF(p[superscript k]). In GF(p) we realize an extensive speedup in modular addition and subtraction routines and some small speedup in the modular multiplication routine with an arbitrary prime modulus p which...

Model of late Pleistocene-Holocene variations in rate of sediment accumulation : Panama Basin, eastern equatorial Pacific

Creator:: Pisias, Nicklas G.
Abstract:: The assumption of constant quartz accumulation for the deep-sea sediment core Y69-106P, taken in the Panama Basin, has been used to date the core and construct a sedimentation rate versus time curve for it. Stratigraphic control for the calculated time scale includes three carbon-14 measurements, the extinction of the radiolarian...

Diagnostic modeling study of a severe narrow cold-frontal rainband

Creator:: Wijesekera, Hemantha
Abstract:: A diagnostic modeling study of the cloud and precipitation processes, and also frontogenesis have been analyzed in a severe narrow cold-frontal rainband with the aid of a three-dimensional, diagnostic cloud model. The results of the model simulations indicate that the heavy precipitation just behind the surface cold front was associated...

Development of volatile compounds in Pinot noir grapes and their contributions to wine aroma

Creator:: Fang, Yu
Abstract:: It is often perceived that late maturity of grape gives a more complex aroma profile to Pinot noir wine, however, there is little understanding of the basic flavor chemistry of grape maturity on wine aroma. The aroma contributing compounds in Pinot noir were first identified by aroma extract dilution analysis...

Public health impact assessment : a science-based methodology for comparing biological agents

Creator:: Appt, Julia R.
Abstract:: Humans have long suffered the effects of disease causing biological agents. Today bioterrorism appears to be on the rise while at the same time global and ecological changes have resulted in the emergence of new diseases. Potential repercussions of an epidemic pose immense challenges requiring a methodical approach to align...

Comparison of MODIS binary and fractional snow cover mapping techniques in the Himalayan Region, Nepal

Creator:: Tuladhar, Preeti
Abstract:: Satellite remote sensing is an effective tool for mapping snow covered area. However, complex terrain and heterogeneous land cover, due to vegetation and patchy snow cover, present challenges to snow cover mapping. This research compares two techniques for mapping snow covered area: binary and enhanced fractional snow cover mapping techniques....
