This thesis work researches the theory and application
of systems performing omnidirectional, non-direct
path optical data communication (ONP systems). Such
systems are characterized by 1) the communication involves
a local, usually circular area; 2) Obstacles are allowed
between a transmitter and the receivers. This is in
contrast to the point-to-point...
FISHNET (Facilities Integrated in a Shared Habitat) is a communication subnet architecture utilizing a hybrid application of point-topoint and broadcast communications to achieve a high degree of network performance. This objective is achieved through utilizing a dual bus structure: a data bus and a control bus. The data bus consists...
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 paper discusses the design strategies for interface of bus
architectures. It also describes the design of interface between the
two popular bus architectures, the Micro Channel and the Nu Bus.
The main objective of this thesis is to develop a procedure for
bus interface design and use this procedure...
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...
Control oriented local area networks (COLANs) are being installed in factories at an increasing rate. Traditionally, process control has operated with a master scheduler (computer) monitoring a number of points in a control grid. As the complexity of today's process control needs grow, the need to process information locally increases....
This paper describes the design and implementation
of COLAN II, a control oriented local area network (LAN).
COLAN II employs a bus interconnection structure and
a token passing method to control the access to the bus.
Major emphasis of the work is on the system structure and
the software operating...
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...
Rapid advances in technology have seen computing move from a
large central computer to desktop microcomputers.
This advance was also
seen in the design of dedicated computers, computers designed to perform a
few specialized tasks or duties.
These computers, or microcontrollers, are
often controlled by a central computer and themselves...
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...
