The material in this paper is divided into the following four chapters for convenience. Chapter 1 explains, how the idea of fault testing changed from testing the machine instructions to testing the hardware in logic circuits. Chapters 2, 3 and 4 present the different approaches considered, namely:
1. Path sensitizing...
Several learning processes which can be used with computing
machinery are discussed in this paper. Consideration is given to what
has been done in this field in the past as well as to what is now
being done. New ideas which might be applied to such study are
introduced.
An...
The reliability of sequential machines is an important factor in
their design and implementation. In this thesis, stochastic sequential
machine models are employed to investigate some of the problems concerning
the reliability of sequential machines. Two different methods
are used to find the reliability required of individual elements. The
first...
In recent years the types of engineering data accumulated by many telemetry systems have become so diversified and complex, and
the environment in which these systems operate has become so restricting
that telemetry systems with increased capabilities and decreased
size are becoming a necessity. Advances in integrated circuitry
techniques satisfy...
With the advancing solid-state technology, it is necessary to
develop new techniques for synthesizing digital networks. The regular
pattern of cellular circuits seems to be the best fitted for the new LSI
technology. Recently, cellular implementations of comibinational circuits
have received considerable attention but very little attention has
been given...
The problem considered is that of causing all the machines of an
array to turn on simultaneously in the least amount of time. Each
machine is a finite sequential machine that can communicate with a
limited number of prescribed neighbor machines.
A solution for a linear array of these machines,...
The use of Regular Expressions to represent the conditions of operations of a finite automaton is becoming popular. A finite automaton can be represented by several regular expressions which are entirely different in out-looks and in structures. It is the primary purpose of this paper to develop several approaches to...
A review of current computer performance and evaluation techniques reveals a lack of an acceptable analytic tool for optimal computer system performance and evaluation. A generalized approach to the formulation of a third generation computer system model is proposed. The approach is used to optimize computer resource utilization and to...
The design of checking experiments for sequential machines
which do not initially have a distinguishing sequence is investigated.
Improvem,Jnts are suggested to an existing method for
augmenting the output logic so that the machine acquires homogeneous
distinguishing sequences. To indicate how the procedure
may be implemented on a computer, elements...
Specifications for a simulation language capable of modeling
fuzzy systems are presented. Actions occurring in the running
model are to be displayed on a graphics terminal in the .form of
modified E-nets. The concept of partial execution of predicates
is introduced in connection with the underlying continuously valued
logic. Fuzzy...
With the advent of LSI, iterative forms of realization
of digital systems are becoming increasingly popular with
system designers. Many problems occurring in digital computer
design render themselves suitable for iterative
realization. These include adders, arithmetic logic units,
coding and decoding circuits and so on. Fault-free functioning
of such systems...
Quantification and comparison of morphological changes over the last ~300 y in Oregon salt marshes provide valuable insights into the tectonic, hydroclimatic, and anthropogenic processes shaping this important intertidal zone. Understanding of the rates and drivers of salt marsh change contextualizes intertidal habitats within the sediment routing system (i.e., source...
Quantification of contemporary sediment and carbon accumulation within Oregon tidal saline wetlands will: (1) fill a critical knowledge gap, and (2) naturally test without complicating variables whether sea level rise or sediment supply primarily control wetland growth. Here we measure vertical accretion rates and carbon burial rates in three Oregon...
The Caribbean Plateau is an oceanic large igneous province (CLIP). A widely accepted model for LIP petrogenesis proposes that these large bodies of igneous rock are formed by decompression melting associated with upwelling mantle plume heads during the initiation of hotspot activity. According to this classical model, petrogenesis occurs over...
The effect of X-irradiation on DNA synthesis in larval salivary
glands of Drosophila hydei was studied using the technique of liquid
scintillation spectrometry and autoradiography. DNA synthesis in
salivary glands of synchronized larvae was measured at successive
stages of third instar development by in vitro uptake of ³H-thymidine
for a...
Conditions were established for inducing pear blossom blast
caused by Pseudomonas syringae (Ps) on both attached and detached
shoots. The incidence of disease was proportional to the log of Ps
population under optimal temperature, moisture and bloom developmental
stage. Highest incidence of infection followed occurrence of a major
exotherm in...
The Curaçao Lava Formation (CLF) records the magmatic and tectonic processes that formed the Caribbean Large Igneous Province (CLIP). A model of the petrogenesis of the CLF was developed using new geochemical and geochronological data. These data include major element compositions obtained using X-ray fluorescence spectroscopy (XRF), trace element concentrations...
Potential sources of inoculum of Phialophora malorum
were investigated. P. malorum was found to be a soil-borne
fungus whose role as a postharvest pathogen of pear is
dependent upon passive dispersal with infested soil. P.
malorum survived in soil under a wide range of conditions,
with greatest survival in cool,...
