Thinning aged Douglas-fir : an analysis of mobilization costs and a log bucking strategy for revenue improvement

Creator:: Pilkerton, Stephen J.
Abstract:: Contract harvest operations have become the preferred approach to reducing the largest cost component of timber production through free market competition amongst logging contractors bidding or negotiating for work. The goal of this research was to investigate economic components of harvesting operations not previously studied for steep slope thinning harvests...

Parameter estimation in system modeling using man-machine interaction and computer learning

Creator:: Wagner, John Arthur
Abstract:: In certain cases in system modeling, parameter search problems are complicated by the availability of scanty and corrupt physical system data and a large number of model parameters. An algorithm using man-machine interaction is presented to attack this type of parameter search problem with the objective of efficiency in the...

Development of a posture prediction model

Creator:: Dendamrongvit, Thidarat
Abstract:: Biomechanical models have been used in designing human work environments to evaluate potential risks to workers before a work environment is constructed. In order for work environments to be modeled correctly, most biomechanical models require as input, an accurate body posture of the worker. This information can be obtained by,...

Urbanization under uncertainty and land use regulations : theory and estimation

Creator:: Cho, Seong-Hoon
Abstract:: This dissertation consists of three papers on land use economics and policies. The first two papers focus primarily on local land use policies and urban development. The third paper addresses the question how environmental amenities affect households' residential choices in a metropolitan area. In the first paper, an option value...

Numerical simulation of cavitating bubble-laden turbulent flows

Creator:: Shams Sobhani, Ehsan
Abstract:: Many engineering devices and propulsion systems suffer from undesirable effects of cavitation; such as degradation in the efficiency of pumps and turbines, generation of noise and vibration on ship propeller, increased drag and erosion of propeller blade, etc. In spite of decades of research on this problem, detailed study of...

An economic model of soil compaction in forestry

Creator:: Stewart, Rodney Aloysius
Abstract:: A model is presented which predicts the net present value of a stand level multi-entry harvest plan. The model accounts for potential volume losses due to harvest-related soil compaction. The goal of this project was to answer five economic questions about the issue of soil compaction in forestry. The five...

The plume model for large utility scale atmospheric fluidized bed combustors

Creator:: Park, Dalkeun
Abstract:: The atmospheric fluidized bed combustor (AFBC) is an alternative to the pulverized coal burner. The size of a utility scale AFBC would be enormous so that the use of large particles is necessary to reduce its size. In modeling the combustion of coal and capture of sulfur released from the...

Modified limiting dilution analysis : a mathematical model with biological interpretation

Creator:: Maier, Stefan H.
Abstract:: A mathematical model of Limiting Dilution Analysis for two limiting parameters is presented and investigated. Limiting Dilution Analysis is a microbiological cell assay developed for immunological application. In the given case we deal with the interaction between B lymphocytes, macrophage derived factor and T-independent antigens. The state of the art...
