A need has existed for an in-depth structural analysis of penstock
bifurcations because they form an integral part of hydroelectric
power plants. Their geometrical complexity has prevented classical
structural analysis from providing an accurate and overall picture of
the stresses in the structure.
Digital computers and the development of finite...
This study describes the development and analysis of a manual
for management and supervisory personnel involved with employee
training programs in sanitary food production in the frozen fruit and
vegetable industry. The physical aspects of the plant, microbiology
of frozen foods, and employee training are discussed in relationship
to the...
Expansive soils in Eugene, Oregon present a problem to
residents, consultants, contractors, and the city government. During
the years 1977 to 1979, the nature and extent of the problem was
identified, including an outline of the local occurrence of expansive
soils and possible engineering solutions to the most often encountered...
This paper describes the design and implementation of
"A multiprocessor node for communication and control"
(MPCC). MPCC is a high speed, high performance local area
network capable of performing real time control tasks. This
is achieved by the concurrent operation of two 8051
microcontrollers, a dual port RAM and the...
The problems of freezing and melting present special
mathematical complexity and, except for the most elementary
one-dimensional cases, require a numerical solution.
However, these problems have a growing importance in
engineering problems because of their application to
metallurgical operations, food preservation, heating and
air conditioning, etc.
In the present work,...
A computer program called SAPWOOD which possesses the
capability of performing linear or nonlinear, static or
dynamic response including seismic excitation for wood-framed
buildings with semirigid connection systems is
presented in this study. Program SAPWOOD is a modification
of the program NONSAP by adding new elements such as a
linkage...
This dissertation investigates by means of computer simulation the potential of a
Band Variable-Inertia Flywheel (BVIF) to store energy for an urban transit bus.
Replacing both a fixed-inertia flywheel (FIF) and a continuously variable transmission
(CVT), the Band Variable-Inertia Flywheel is capable of accelerating a vehicle
from rest to a...
Many important application problems in engineering can be formalized as nonlinear
optimization tasks. However, numerical methods for solving such problems
are brittle and do not scale well. For example, these methods depend critically
on choosing a good starting point from which to perform the optimization search.
In high-dimensional spaces, numerical...
Standard methodologies exist for testing and characterizing digital circuits but the
same cannot be said of analog circuits. Though much theoretical work has been done to
model the linear and nonlinear aspects of analog circuits, a firm practical background for
the design of testable analog cells has yet to be...
A transient code (TFETC) for calculating the temperature
distribution throughout the radial and axial positions of a
thermionic fuel element (TFE) has been successfully developed.
It accommodates the variations of temperatures, thermal power,
electrical power, voltage, and current density throughout the
TFE as a function of time as well as...
