Semi-emperical [sic] methods for estimating evapotranspiration in a modified marine climate

Creator:: Smith, Jerome Francis
Resource Type:: Masters Thesis
Full Text:: -empirical evapotranspiration (ET) estimating methods in a modified marine climate was carried out from May

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...

Optimal harvesting of continuous age structured populations

Creator:: Smith, Steven J.
Abstract:: We investigate the optimal harvesting strategies for McKendrick type population models. Models of this type endow the population with a continuous age structure. They consist of a partial differential equation with a boundary condition which involves an integral of the solution. We study two problems, the first concerns the yield...

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...

Digital simulation of multi-dimensional random processes and its applications

Creator:: Ahn, Gil Soo
Abstract:: This dissertation introduces a method which can simulate multi-dimensional Gaussian random processes by the superposition of sine functions The fast Fourier transform technique is incorporated into the simulating method to facilitate saving of computer time. In view of the fact that the fast Fourier transform play important roles in digital...

Analysis of dichotomous response models for low-dose carcinogenic risk estimation

Creator:: Tabesh, Taraneh
Abstract:: Several dichotomous-response models of carcinogenesis are discussed and their implications for low-dose risk estimation are examined. In addition, a pharmacokinetic model incorporating non-linear kinetics is studied and the results are investigated with respect to multiple-pollutant exposures. None of these models appears to suggest the existence of "thresholds". The analysis of...

Passive source tracking from spatially correlated angle-of-arrival data

Creator:: Haisch, Hansjoerg
Abstract:: This thesis presents a simulation technique for the post-detection of a point-source trajectory in an isotropic, stationary random medium. The two-dimensional source location is estimated from spatially correlated angle-of-arrival data which are collected simultaneously at two sensor positions. We assume that the data are collected at discrete, constant time intervals...
