Heuristics based on Monte-Carlo Integer Programming (MCIP) and Tabu Search
(TS) techniques were developed for generating easily implementable bucking rules that are
applicable to entire stands (as opposed to individual stem classes), and for selecting the
rule-set that provides the best feasible solution (given log prices and market constraints).

Public land ownership withdraws property from the tax base of local
property tax districts. Publicly-managed lands occupy approximately 17.5
million acres of forested lands in Oregon (inclusive of federal, state, and county
ownership). To compensate local taxing districts for foregone property tax
collections, Congress enacted a series of federal revenue-sharing...
Since the dawn of the computer age, there has been a push to create miniature
devices. These devices were initially integrated circuit (IC) devices to perform
calculations for computers. As the technology progressed, the scope of the devices
diverged to included microelectromechanical (MEMS) devices, meaning that the devices
perform mechanical...
As the drive continues to reduce the size of Printed Wiring Assemblies (PWAs),
improve performance of electronic assemblies, and reduce costs of these products,
reliable secondary (bottom) side reflow operations must be developed. Attaching Surface
Mount Technology (SMT) components to the secondary side of a Printed Circuit Board
(PCB) is...
Advancements in the sophistication and complexity of modern electronic systems are creating a need for highly integrated systems with ever higher operational frequencies. The economical demands of these systems dictate that they be implemented using low cost fabrication technologies, such as digital CMOS. One of the major challenges facing circuit...
A series of experiments was performed to determine the feasibility of genomic
DNA-based methods for ecological and physiological studies of dominant bacteria from
complex natural systems. Two approaches, bacterial chromosomal painting (BCP) and
environmental genomics (EG), were evaluated for the potential to identify and enumerate
specific bacterial groups in situ...
