Attitude control in quadrotor Unmanned Aerial Vehicle (UAV) systems is traditionally managed by optimal control loops tuned to minimize errors in performance. While robust, these loops perform sub-optimally in dynamic and unpredictable environments which inspire new interest in sophisticated solution and approaches such as reinforcement learning (RL) approaches which should...
A study to investigate the role of population sex ratio in gender switching in an A. Triphyllum population along with the role of different environmental factors and management activities on plant size and population sex ratio in two different populations
This thesis discussed how motifs of height and depth in Black literature highlight Black characters’ inability to form positive racial identities. The thesis uses three canonical pieces of Black literature, Passing, Native Son, and Plum Bun, to demonstrate that Black characters who try to reimagine White space are forced into...
The 2005 NHL Lockout instituted a hard salary cap, which is the most limiting salary cap of the major US sports leagues. The NHL as a result doesn’t have the luxury of overpaying or dumping a contract as other professional sports leagues have, which places a huge constraint and emphasis...

Advances in machine learning and artificial intelligence (AI) are enabling computers and robotics to take on an increasing number of work-related tasks that previously were the sole domain of humans. This trend raises questions: Which jobs will be most susceptible to replacement by automation? How many workers risk being replaced?...
Using transcripts from Kansas State University Libraries’ (KSUL) virtual reference services (VRS), an experimental design was created to investigate the value and impact of different natural language processing techniques in the context of creating predictive models. Models were created to use only the first few word tokens supplied by VRS...
With a glut of competing priorities, the financial industry faces major challenges in extracting timely, relevant, and specifically-focused information from text. Without clear-cut business cases, making the investment in text analysis methods does not justify the return on investment. Furthermore, the business landscape continues to become increasingly complex, and at...
Minnesota is the land of 10,000 lakes (technically 11,842 > 10 acres)! This bold proclamation can be seen everywhere from license plates to tourism pamphlets; it reveals how much water matters to the state on not only a commercial level, but as the very identity of the community. At the...
After large-scale disturbances such as fire, seeding can be necessary to reestablish a plant community and prevent soil erosion. While native plants are ideal for providing ecosystem services and supporting wildlife, currently seeded natives often fail to establish in disturbed landscapes. Further, reseeding with native plants is often hindered by...
Climate change, whether referring to historic ice ages or contemporary shifts in global climate patterns, has been linked to wide-ranging and regionally variable changes in biotic communities.
Understanding the factors that drive the maintenance of polymorphisms in plant populations has long been of interest to evolutionary biology. Variation in floral traits has often been attributed to selection by pollinators, but recent evidence suggests that other biotic and abiotic agents may also contribute to floral trait differentiation. In...
Because long-chain n-alkanes (n-C21 to n-C37) are found in the epicuticular leaf waxes of all vascular plants and are stable, long-lived molecules, the study of their molecular and isotopic compositions stands to serve as a potentially powerful tool in the fields of modern chemotaxonomy and paleoecology. This study attempts to...
Trees in urban areas offer ecosystem services like carbon sequestration, storm water attenuation, reduction of energy used in buildings and wildlife habitat. Cities invest substantial funds and resources to maintain a healthy urban forest, and much research has been done to improve its resiliency and sustainability. Studies have been done...
The environmental and plant physiological correlates of plant growth and reproductive effort in the locally threatened orchid, Cypripedium candidum Muhl. ex Willd were examined in the context of a conceptual model of demographic and reproductive trade-offs, focusing on three Illinois populations. This study addresses the current status and long-term trends...
Nitrogen (N) deposition can alter belowground microbial communities, especially ectomycorrhizal (ECM) fungi, resulting in a reduced ability of associated trees to access organic nutrients. This study tested whether N addition decreases ECM species richness and shifts ECM species composition across spatial scales in a subtropical slash pine (Pinus elliottii) plantation...
The tallgrass prairie once dominated much of the mid-western United States. Today, this highly productive system has been severely reduced, contributing to an array of environmental problems. The recent renaissance in natural area restoration and stewardship of the tallgrass prairie in the Chicago Wilderness region (Illinois, USA), especially in the...
Identifying factors that shape the spatial distribution of genetic variation within and among natural populations is crucial to understanding many population> and landscape>level processes. In this study, I characterize the strength and extent of spatial genetic structure in Oenothera harringtonii (Onagraceae), an insect>pollinated, gravity>dispersed herb endemic to the grasslands of...
Pollination is a reproductive necessity in the majority of the world’s flowering plants. Pollen limitation threatens plant reproduction, particularly in self-incompatible species. Although assessing pollen limitation usually requires pollen supplementation experiments, alternative methods support the findings of traditional pollen supplementation experiments.
