Currently, the technologies used to separate lignocellulosic biomass into its component parts (cellulose, hemicellulose, and lignin) and enzymatically hydrolyze the cellulose to glucose for conversion to ethanol could be improved economically and in terms of efficiency. A major impediment to utilizing the biomass is the presence of residual lignin. The...
Vibrio parahaemolyticus, a naturally occurring halophilic pathogen, is seasonally abundant in marine and estuarine environments. It is also the leading cause of gastroenteritis in humans world-wide. Numerous outbreak incidences associated with the pathogenic Vibrio parahaemolyticus contaminations in oyster products have raised public-health concerns as well as economic challenges to the...
The purpose of the study was to explore the ethnic identity of
Chinese American adolescents through the investigation of
relationships between ethnic identity and selected demographic,
sociocultural, and psychological characteristics.
Data were obtained from 106 Chinese American youth between the
ages of 14 and 21 through the use of two...
Currently, a popular approach to image classification uses the deep Transformer architecture. In a Transformer, the attention mechanism enables the model to learn efficiently with fewer computational resources than the convolutional neural networks (CNNs). In this thesis, we study the sparse attention mechanism widely used in the Transformers developed specifically...
Active contour models have been widely applied to image segmentation and
analysis. It has been successfully used in contour detection for object recognition,
computer vision, computer graphics, and biomedical image processing such as X-ray,
MRI and Ultrasound images.
The energy-minimizing active contour models or snakes were developed by Kass,
Witkin...
Optical sensing technologies are pivotal in the manufacturing process, specifically in defect detection, tool condition estimation, and monitoring. The research aims to enhance the accuracy, efficiency, and reliability of manufacturing metrology by employing optical sensing technologies, such as laser profilometers and image processing techniques. The dissertation proposes intelligent and flexible...
Photolysis of pentachlorobenzene was carried out in the absence
of an electron donor species at 254 nm in cetyltrimethylammonium
bromide surfactant solution. The results are consistent with the
excited triplet undergoing homolytic cleavage of a C-Cl bond in
competition with formation of the excimer, in which the radical anion
undergoes...
Since many 1, 4, 5, 6-tetrahydropyrimidines have become available
and commercially useful in recent years, a study of the chemistry
of certain of these compounds has been undertaken.
2-Hydroxy- and 2-mercapto-1, 4, 5, 6-tetrahydropyrimidine
have been synthesized by the condensation of urea and thiourea, respectively,
with 1, 3-propanediamine, with yields...
