Simulation of a helicopter yarding system in old growth forest stands

Creator:: LeDoux, Chris B.
Abstract:: Helicopter yarding systems have become a popular tool in removing timber from steep slopes, sensitive soils, limited access areas, and environmentally sensitive stands. Little is known about the system's dynamics. This study is part of a research project to explore "advanced" logging systems as to their economic efficiency and environmental...

Investigations concerning heat transfer involving wedge-shaped configurations

Creator:: King, John Michael
Abstract:: The temperature field inside a "truncated" wedge is investigated. For this purpose the two dimensional Green's function of the heat equation for this domain is established. Further applications of these results center around a problem of heat conduction investigated by Lebedev.

A dynamic model of exchange rate in relation to international trading

Creator:: Sun, Keong-wah Gary
Abstract:: It is popular belief that the volatility of the exchange rate is due to the balance of payments, which in turn is mainly influenced by the balance of trade. A closed-loop dynamic economic model is proposed to describe and analyse the effect of the international trade of a country on...

Parameter sensitivity algorithm for a digitally-modelled direct current excitation system

Creator:: Dearborn, Barry Claude
Abstract:: An algorithm for computing the parameter sensitivities of an excitation system for a hydroelectric generation system is developed for model analysis in this thesis. The IEEE Type 1 excitation system representation, linked with a simplified alternator and voltage regulator equivalent, provide a closed-loop model for digital simulation. Parametric sensitivities are...

A branch and bound algorithm applied to field office location

Creator:: Lovro, Daryl Stanley
Abstract:: This thesis develops a model for locating field offices for the Motor Vehicles Division of Oregon. The locations are determined by minimizing the total cost to the Public. This is reasonable because the Public finances the operation and the opening of the offices through tax dollars, and it bears the...

Instrumentation system for high speed data sampling of electrical machinery

Creator:: Brisbine, Glen Edward
Abstract:: The objective of this thesis is to develop criteria for a data acquisition system for electrical machinery capable of sampling a signal every 0.2 msec with a desired accuracy of 0.1%. The system to be measured includes both AC and DC voltage and current signals from several points. The main...

An analysis of the infinite periodic lattice approximation used in unit cell calculations

Creator:: Thomas, Mark Stephen
Abstract:: Unit cell or pin cell calculations form the basis for most nuclear core modeling. Because of this, it is of primary importance to perform these unit cell calculations accurately. The subject of this thesis is the analysis of one of the major approximations made in unit cell modeling, the infinite...

Application of pattern recognition to a human behavior problem

Creator:: Chang, Chia-hao
Abstract:: Pattern recognition techniques and their application to a consumer behavior study are presented. The Local Majority Method (LOMAME) utilizes a set of prototypes and corrective factors which undergo a training cycle before being utilized as pattern classifiers. Its advantages over the Minimum-Distance Method and the Fix and Hodges Method are...
Resource Type:: Masters Thesis
Full Text:: FORTRAN model of the LOMAME is first applied to standard pattern recognition problems of "A-and-R" and

Hybrid computer simulation of wind-driven ocean currents

Creator:: Vithayathil, Francis Joseph
Abstract:: A simulation method using a hybrid computer is developed in this dissertation to enhance the study of wind-driven ocean circulation. The simulation is based on the mathematical model developed by Ekman. Pure digital simulation is not economical due to excessive computer time required for the solution of the partial differential...
