This thesis is concerned with designing and simulating waste
energy retrieval systems from large transformers to provide heating and
cooling of a control house. The transformer selected is Transformer
Bank One at the Ross Substation in the BPA system. The unit is an
ASEA 250 MVA transformer with forced oil,...
The problem of a fixed rectangular structure of unit width in a
train of simple harmonic normally-incident waves is modeled. The solution
allows for variable (1) length and draft of structure, (2) differing
depths in the three (fore, aft, and beneath the structure) distinct
regions, and (3) wave period. The...
Consider the situation where one is faced with a sequence of knapsack type problems which involves additional constraints on the permissible number of certain types of knapsack fillers to be used over the sequence. This research is concerned with determining good and perhaps optimal solutions which maximize the total value...
A computer code capable of modeling the burnup dependent static behavior
of a boiling water reactor was developed. The code calculates
three-dimensional quarter core power distributions using a simulated
two-group diffusion theory model. Thermal-hydraulic calculations account
for the interaction between power, coolant flow, and void fraction
distributions. Cross sections are...
Lamellar x-ray diffraction was studied from thin films of L-α-1,2-dipalmitoyl lecithin (DPL) and a 1:1 mixture (BrDPL) of L-α-l-palmitoyl-2-(9- bromopaimitoyl) lecithin and its 10-bromo analog. The specimens had high lamellar order, with an upper bound on the mosaicity of 6 mrad (0.4°) for DPL and BrDPL. With various water contents,...
This report presents the results of an input-output analysis for the Clatsop County economy of 1977. Financial information was collected from 292 firms in the county. The local economy was divided into 26 sectors. The financial information from the sample was used to estimate the economic interactions between these sectors...
In this thesis, computer simulation and evaluation of solar cooling systems are presented. The simulations were conducted using the TRNSYS program, developed at the University of Wisconsin. The TRNSYS program was modified by the addition of new models for the solar collector with high fluid thermal capacity, the absorption cooler,...
A multiple stage crosscurrent packed column suitable for gas-liquid
mass transfer was constructed and operated. The absorption
column consisted of a rectangular box constructed of plexiglass and
metal. Deflection baffles were positioned at regular intervals on
opposite sides of a central packed section to divert the gas phase
into the...
Finite order autoregressive models for time series are often
used for prediction and other inferences. Given the order of the
model, the parameters of the models can be estimated by least
squares, maximum likelihood, or the Yule-Walker method. The
basic problem is estimating the order of the model. A number...
