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,...

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...

Some mathematical models in ecology

Creator:: Engstrom-Heg, Verna Louise
Resource Type:: Masters Thesis
Full Text:: mathematical model that closely simulates nature Is likely to Involve a great deal of computation. Therefore

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...

Advanced numerical modeling of the Lorentz mixing process

Creator:: Hager, Michael B.
Abstract:: There are numerous techniques for improving the mixing of fuel and oxidant species. However, many of these methods cannot be applied to combustion systems due to material limitations. A means of mixing the reacting species without physically invading the flow stream is therefore desired. In this work, induced electromagnetic forces...

A "mildly inconsistent" method for accelerating upstream corner balance transport

Creator:: Gulick, John C.
Abstract:: A new method for accelerating the Upstream Corner Balance (UCB) discretization of the equation of transfer is introduced. The inconsistent acceleration equations for the UCB discretization are derived by applying the "Modified 4-Step" diffusion synthetic acceleration technique not to the UCB discretization, but instead to the simple corner balance (SCB)...

Tracer experiments in a non-uniform porous medium : implications of diffusive mass transfer on the late-time breakthrough behavior

Creator:: Freiherr von Schwerin, Claudius
Abstract:: Mass transfer processes were evaluated in an artificial, non-uniform porous medium with a power law distribution of diffusion rate coefficients obtained from physical characterization of solute and porous medium. Breakthrough curves of several pulse experiments conducted at different velocities were compared (1) to analytical expressions for concentrations at mass transfer...

A simulation of the operation of a log landing for a heli-stat airship in old-growth timber

Creator:: Gerstkemper, John C.
Abstract:: This paper discusses the development of a computer simulation program for the operation of a log landing for the proposed Helistat airship. The first part of the paper describes the time study used to develop production rates for the chasers, buckers, front-end loaders, and skidders to be used on the...

Predicting skidder productivity : a mobility approach

Creator:: Gibbons, Daniel J.
Abstract:: The principles of mobility are applied to the forest setting to simulate the movement of logs with a rubber tired-skidder. A computer program was written to perform the analysis . Vehicle-terrain and logterrain interactions are the resistances which must be overcome by the available vehicle power. The rate at which...
