Shadows portray helpful information in scenes. From a scientific visualization standpoint, they help to add data without unnecessary clutter. In video games they add realism and depth. In common graphics pipelines, due to the independent and parallel rendering of geometric primitives, shadows are difficult to achieve. Objects require knowledge of each other and therefor....

Rice yield is adversely affected by various abiotic and biotic stresses. Jasmonic acid (JA) signaling has been implicated in stress response of plants. The nuclear localized basic helix loop helix (bHLH) Myc2 transcription factor is known to be a master regulator of genes involved in the response of the JA-mediated signaling pathway during stress and plant development. ....

Strings play an important role in many areas of computer science. Searching pattern in a string or string collection is one of the most classic problems. Different variations of this problem such as document retrieval, ranked document retrieval, dictionary matching has been well studied. Enormous growth of internet, large genomic projects, sensor networks, digital libra....

The current study examined alcohol consumption among Turkish adolescents through the lens of Agnews General Strain Theory (GST) using data drawn from the 2008 Youth in Europe Survey. Although considerable attention has been paid to problematic alcohol consumption among adolescents, extant research has remained limited to western countries. Similarly, much of the support....

Previous suicidal ideation and attempt are the strongest predictors of subsequent completed suicide, which is the second leading cause of death among youth today. Research shows that the risk factors for adolescent suicidal behaviors can be grouped into demographic, social, and psychological categories, so a broad theoretical framework is needed to examine the range of ....

The objective of this work is to develop an improved manufacturing process for microstructured ceramic components that is based on co-extrusion. Co-extrusion of structured feedrods holds promise for development of multi-layered, functionally graded and/or textured structures. However, it requires a polymer binder that is difficult to remove before structures can be sint....

Computational studies are very important to gain an insight into reaction mechanisms and in interpreting and understanding complicated experimental observations. This report contains a discussion on computational studies performed on bimetallic catalysis and on X-ray absorption spectroscopy of insulators. The viability of a bimetallic rhodium and cobalt catalysts for in....

Graphene could be potentially important for a broad range of photonic and optoelectronic applications. For such graphene-based applications it is critical to enhance the absorption of light in graphene monolayers in order to achieve near total absorption. Several structures have been proposed to enhance light absorption in graphene at visible and infrared wavelengths su....

This thesis focuses on applying machine-learning algorithms on water depth inversion from remote sensing images, with a case study in Michigan lake area. The goal is to assess the use of the public available Landsat images on shallow water depth inversion. Firstly, ICESAT elevation data were used to determine the absolute water surface elevation. Airborne bathymetry Lid....

Crayfish are important for stability, determining ecosystem structure, and ecosystem functions in freshwater habitats. Louisiana has many endemic species of crayfish, but most are poorly described. This study investigated the populations of some of the lesser known crayfishes in the South Central Plains. Specifically, the goals were to examine movement, movement across ....

Atrazine, one of the most widely used herbicides in the United States, is commonly applied to southern lawn grasses to reduce weed encroachment. According to the EPA, atrazine is also one of the most frequently identified herbicidal compounds in surface and ground waters. Given the increased management intensity of home lawns in Louisiana, coupled with urban sprawl and ....
