This thesis focuses upon whether stressful aspects of an organism's environment are reflected by that organism's shape. It presents an application of the powerful thin-plate spline and relative warp methods from morphometric analysis to demonstrate the overall utility of morphometrics in detecting environmental stress in an estuarine flatfish, the English...
An experiment was established in 1992 in the central Sierra Nevada Mountains of California to assess the effects of high levels of surface organic residues, severely compacted soil, and shrub competition on the development of mixed conifer plantations. This study was conducted in 1997 to determine if selected combinations of...
Until now the topic of motion estimation, as used in video compression, has been dominated by search methodologies which are modifications of an exhaustive search. This research takes a completely new approach by applying two evolvable search algorithms, the Genetic Algorithm and the Genetic Program, to the area of motion...
The application of the personal computer in the area of real-time process control
is investigated. Background information is provided regarding factory automation and
process control. The current use of the PC in the factory for data acquisition is
presented along with an explanation of the advantages and disadvantages associated
with...
This research applies the biologically inspired, artificial evolutionary processes of Genetic Algorithms and Genetic Programming to digital hardware circuit synthesis and minimization. In this new application, three approaches are taken to genetic hardware development. First, as a method for logic synthesis, Genetic Programming is applied to the building of logic...
This thesis describes the design of a baseband digital predistortion
architecture for radio frequency (RF) amplifier linearization. Existing amplifier
linearization techniques are first examined. The nonlinearity of an amplifier can
be characterized as amplitude-to-amplitude distortion and amplitude-to-phase
distortion. The distortion can be corrected by providing a predistorted driver
signal (both...
TASKMASTER is an experimental microcontroller node of a real-time control
oriented network which was proposed by James H. Herzog and Tinggui Zhang to
demonstrate the feasibility of a task oriented control structure in performing distributed
control actions. This study is a continuation of research involving the TASKMASTER
network.
A high...
In recent years, integrated circuit technology has
spawned the development of many low cost and high performance
microprocessors and microcontrollers. With these devices,
there is an increasing interest in the implementation of
distributed control networks, utilizing microprocessors in the
control nodes.
In this work, a low-cost liquid crystal display (LCD)...
A Hybrid Meshnet LAN, a new local area network architecture, has been proposed by Dr. Cheoul-Shin Kang and Dr. James Herzog. It provides for distributed control hybrid architecture which is good for effective load sharing under various local area network environments. Hybrid Meshnet has a dual channel structure, a token...
This thesis describes the design of a RISC architecture
for high speed data acquisition. The structure of existing
data acquisition systems is first examined. An instruction
set is created to allow the data acquisition system to serve
a wide variety of applications. The architecture is designed
to allow the execution...
