A systematic optimization of the Cohen class time-frequency
transformation for detecting the parameters change is developed.
The local moments approach to change detection is proposed and a
general formula for the local moments is derived. The optimal
kernel functions of the time-frequency transformation are determined
based on the combined criteria...
This study examined the experiences of five Korean American mothers in Oregon and California who have children with disabilities using qualitative research analysis. The mothers' adaptation processes were individually analyzed, and these mothers' overarching experiences were discussed with three major themes: (a) caring for family cohesiveness, (b) needs for social...
In this dissertation, I qualitatively examined the meaning of mothering a child with autism in two countries: the United States and South Korea. The overarching research question focused on how sociocultural ideas about mothering and disability, particularly autism spectrum disorders, shape women’s understanding of themselves and their children with disabilities....
Ever-increasing size, complexity and operation costs in modern
power systems have stimulated the intensive study of an optimal
Load Shedding and Generator Rescheduling (LSGR) strategy in the
sense of a secure and economic system operation.
The conventional approach to LSGR has been based on the application of LP (Linear Programming)...
The relevance of domestic and foreign capacity utilization rates in forecasting
future inflation rate has been investigated empirically, using five industrialized
countries for which the comparable data are available.
It has been found that capacity utilization rates, both domestic and foreign,
have a long run stable relationship with domestic inflation...
The flux-gradient relationship of water vapor Fq was obtained from the Cooperative Atmosphere-Surface Exchange Study-1999 (CASES-99) field experiment, which was conducted on a flat and grassy field in the southeastern part of Kansas, USA, during October 1999. The CASES-99 data include turbulence measurements of wind, temperature, and vapor density along...
School forests in South Korea are trees and vegetation areas within schoolyards, and they provide natural environments for schools and neighborhoods. After the Korea Forest Service (KFS) and local governments create these school forests, the management of school forests transfers to the host schools. Some studies suggest that experiences with...
In this dissertation the interactions between hydrodynamics, sediment suspension and transport, and morphological evolution in the surf zone was investigated with a large-scale laboratory experiment data, CROss-Shore Sediment Transport Experiment (CROSSTEX). The data set included comprehensive measurements of water surface elevation, fluid velocity, sediment concentration, and morphology for irregular waves...
Sulforaphane is an isothiocyanate derived from cruciferous vegetables and has been under investigation as a cancer chemopreventive agent for over two decades. The compound is well tolerated and has been shown to slow cancer progression in several different pre-clinical models of carcinogenesis, such as of the lung, breast and colon....
