The zirconium-chromium phase diagram was investigated in the
region between 40% and 85% chromium. The ZrCr₂ intermetallic
compound which has been the source of some controversy was especially
considered. It was found that ZrCr₂ transforms from the low
temperature C-15 (MgCu₂, FCC) structure to the high temperature
C-14 (MgZn₂, HCP)...
This thesis presents the creep properties and the relations
between stress and strain of "Expanded 460KV", "Chukar" and
"Drake" conductors. The basic theories of the effect of load,
material, and temperature on the conductor are also briefly
discussed.
The long time creep curve of a conductor appears as a
straight...
Impedance measurements are increasingly demanded in modern CMOS sensing systems as impedance is the most common electrical signal obtained from sensors, delivering physical, chemical and biomedical quantity changes. Impedance sensing for wide interested frequency, broad dynamic range, and various sensor interfaces has numerous challenges, especially targeted in CMOS miniaturization with...
A new system called sequential/parallel matrix grammars
for two-dimensional pattern processing is introduced and studied.
Miscellaneous language operations such as union, catenation (row
and column), Kleene's closure (row and column) and substitutions
are investigated. The equivalence of sequential/parallel matrix
languages and finite-turn repetitive checking automata is established.
Hierarchies for both...
While much work has been done in estimating software reliability, little attention is paid to predict reliability as early as at the design time. In this report, we present our initial research results of building an early stage software reliability prediction model.
In Part I, we will first investigate and...
In genome-wide association studies, it is often challenging to have consistent findings from independent studies. This "lack of reproducibility" issue is partially caused by the relatively small sample size compared to the number of genetic markers in every single study. Therefore, researchers have developed statistical methods to integrate multiple studies...
Presently, the production of wood composites relies on the formaldehyde-based wood adhesives such as phenol-formaldehyde (PF) and urea-formaldehyde (UF). However, their dependence on exhaustible fossil fuels and the emission of carcinogenic formaldehyde prompt to develop an environmentally friendly adhesive from renewable natural resources. This work focuses on development and characterization...
Learning to recognize objects is a fundamental and essential step in human perception and understanding of the world. Accordingly, research of object discovery across diverse modalities plays a pivotal role in the context of computer vision. This field not only contributes significantly to enhancing our understanding of visual information but...
Machine vision is widely used in scientific areas and non-wood using
industries, but the extreme variability of wood has limited its adoption by forest
products industries. However, it is now becoming a key factor in further automation
of the forest products industry. As a very important part of machine vision,...
