Dimethylamine (DMA), in addition to the alkaloids hordenine
and gramine, has been suggested as a potential precursor of nitrosodimethylamine
(NDMA) in malt. Analytical procedures were adopted
and applied to extract and quantify DMA from malt, green malt,
malt roots and raw barley. Ground malt was extracted at room
temperature with...
The Advent of multi-cores allows programs to be executed much faster than before. Cryptoalgorithms use long-bit words thus parallelizing these operations on multi-cores will achieve significant performance improvement. However, not all long-bit word operations in cryptosystems are suitable for parallel execution on multi-cores. In particular, long-bit words used in Elliptic...
The objective of this study is the development and
verification of an analytical solution for an unsteady
flow field partially occupied by a permeable structure.
Flow is induced by a small amplitude incident wave
train and the permeable structure may contain multilayered
anisotropic but homogeneous material. The analytical
solution developed...
The purpose of the study was to investigate practical guidelines based on empirical evidence for effective website design, including both home page and product pages. This research consists of two consecutive empirical studies. Study 1 was one factor (home page design: image- vs. text-oriented home page) between-subjects design with two...
Since the Uruguay Round Agreement on Agriculture (URAA) in 1994, global competition in Korean agricultural markets has significantly increased. The objective of this dissertation is to identify the effects of trade liberalization on productivity and pricing in the Korean rice market (Essay 1 and 2) and on the entire agricultural...
The purpose of this study was to design and to implement
a practical Ethernet Local Area Network (LAN)
board for the Macintosh II computer system. A survey
of the literature provided a general definition of
LANs, a reference model for network layers, specifications
for an Ethernet LAN, and information on...
The purpose of this study is to investigate the performance and stability of
the gas-injection enhanced natural circulation in heavy-liquid-metal-cooled systems.
The target system is STAR-LM, which is a 400-MWt-class advanced lead-cooled
fast reactor under development by Argonne National Laboratory and Oregon State
University. The primary loop of STAR-LM relies...
Flowering is the primary trait affected by ambient
temperature changes. Plant microRNAs
(miRNAs) are small non-coding RNAs playing an
important regulatory role in plant development. In
this study, to elucidate the mechanism of
flowering-time regulation by small RNAs, we
identified six ambient temperature-responsive
miRNAs (miR156, miR163, miR169, miR172, miR398
and...
This thesis presents a novel methodology that enables power efficient video decoding
in an embedded system based on MPSoC (Multiprocessor System on Chip). This
methodology is a physical combination of parallel processing which reduces power
consumption of processors by exploiting thread-level parallelism and Dynamic
Voltage Frequency Scaling (DVFS) that allows...
