The feasibility of using the Franz-Keldysh effect in practical
light intensity controlling devices was investigated.
Reverse-biased diodes made from CdS were implemented to obtain
high electric fields necessary for the effect. The three types of
diodes studies were: MIS, metal-semiconductor barrier, and p⁺-n
heterojunction. An expression for the change in...
This paper investigates the benefit of various parallel processing
architectures for a Command and Control system for the Royal
Thai Air Force. Parallel processing has been shown to be useful
for air defense and air traffic control applications. Its advantages
are examined within the constraint imposed by the available
resources...
The dynamics of land use in the State of Oregon are simulated
on a digital computer. The introductory chapter outlines the complex
nature of the problems facing the post-industrial society and argues
that the scientific and professional estates share in the responsibility
for public policy formulation. The second chapter .presents...
The question of the suitability of Walsh functions or
similar bi-valued functions used as a radar electromagnetic
carrier waveform is considered. Walsh functions are
described and effective sinusoidal steady state transfer
functions are defined for transmission elements, antenna
systems, and propagation media.
The argument is made that the unit impulse...
It has been established that bilinear models
occur frequently in nature and offer some important
advantages from the standpoint. of controllability,
optimization and modeling. The estimation of
bilinear systeim models from the Measurements
of input-output data are discussed. In the
first approach a parametric model of a discrete-time
linear system...
In this dissertation, a new computational method for equality constrained nonlinear programming is developed. Specifically, problems of minimizing a nonlinear objective function f(x) subject to constraints h(x) = 0, where f is a scalar valued, x is an n-vector and h is a m-vector with m < n is considered....
A new modular loop architecture for distributed computer
systems has been developed and compared with three of the most
prominent loop architectures currently being used. The competitive
loops with which the new architecture has been compared
are the Newhall loop, the Pierce loop and the DLCN loop. The four
loop...
The purpose of this research is to design a high level language
(HLL) suitable for microprogramming. A top down design technique has
been adopted which makes the language design process simple and
accurate.
The primitive operations of a high level language for producing
emulators is shown to include special purpose...
An advanced forward 'area tactical radar network, now under
conceptual development by the Air Force Electronic Systems Division,
can be viewed as a novel form of computer network but with
other unique problems resulting from the specialized nature of the
application. The proposed network will link together a number of...
The electrical and optical properties of semi-insulating, epitaxial and ion-implanted GaAs and InP have been characterized and analyzed. Electron and hole traps in semi-insulating GaAs and InP, with activation energies ΔE[subscript T] ranging from 0.16 ± 0.01 to 0.98 ± 0.01 eV, have been detected and characterized by Photo-Induced Current...
