Recent statistics suggest that the construction industry continues to experience poor project performance. Specifically, construction productivity has witnessed a meager annual growth of 1% over the past 20 years while the industry constantly records both a high number of fatalities and a high fatality rates relative to other industries. The...
This thesis presents an effective control design methodology using a one-step-ahead prediction adaptive control law and an adaptive control law based on a Lyapunov function. These control law were applied to a highly maneuverable high performance aircraft, in particular, a modified F/A-18. An adaptive controller is developed to maneuver an...
Part of the Y chromosome in humans is detectable as a brightly
fluorescing body in interphase nuclei stained with quinacrine dyes.
This fluorescent body when stained with quinacrine mustard dihydrochloride,
in cells from some 15 human subjects, was seen to manifest
a variable morphology which appeared to be related to...
Ship turnaround time at a marine containerport is an important
measure of the port's efficiency and attractiveness. Both the speed
and quality of load planning affect the length of turnaround time
considerably. Past attempts at computerizing the load planning
function have been unsatisfactory and have not reflected the port's
objective...
This paper uses general equilibrium static and dynamic
models to examine the economic and environmental effect of
capital liberalization policy based on the general
equilibrium static and dynamic models. The first topic
develops a static general equilibrium model of a small open
economy in the presence of unemployment with three...
Technological growth in agriculture increases crop output but it could lower output price in the market. Economic impact assessment in ex-ante analysis usually does not include these indirect supply responses, which can overestimate the economic potential of new technology. This dissertation provides an integrated farm-level ex-ante impact assessment model to...
With the ever-increasing demand for portable devices used in applications
such as wireless communication, mobile computing, consumer electronics, etc.,
the scaling of the CMOS process to deep submicron dimensions becomes more
important to achieve low-cost, low-power and high-performance digital systems.
However, this downscaling also requires similar shrinking of the supply...
The purpose of this study was, first, to investigate whether there
is a vitamin B-6 requirement for carnitine synthesis and, second, to investigate
the effect of fasting on vitamin B-6 metabolism. An experimental
group of 72 rats (6 per group) were fed either a vitamin B-6 deficient
diet (-B6) (ad...
This study examined the relationships among authoritarian
parental attitudes, home environments, parental attitudes
toward the children's freedom, and the cognitive performances
of kindergarten children. Socioeconomic status of the family
and sex of child and parent differences were also examined.
Subjects consisted of 73 pairs of Korean parents and their
children....
This study described how and why a Korean elementary teacher taught mathematics as he did. Specifically, the study sought to describe his beliefs about the teaching and learning of mathematics and relate them to patterns of classroom interaction and norms.
An ethnographic inquiry guided the study of one third grade...
