• #### Oak expansion in the Chautauqua Hills Kansas: a regional assessment of historic change ﻿

(Wichita State University, 2012-05)
Woody plant expansion into grasslands and savannas is a globally occurring process which can cause loss of biodiversity and alter biogeochemical cycles. The Chautauqua Hills, in southeast Kansas, is the northernmost extent ...
• #### Objective and perceptual measures of physical health, nutrition and hydration relative to swallowing function in self-reported healthy older adults in a continying care community ﻿

(Wichita State University, 2012-05)
The onset of dysphagia (swallowing difficulty) is associated with increasing age and the diseases that frequently occur with increasing age. Dysphagia increases the risk of dehydration and malnutrition with subsequent ...
• #### Oblique machining of uni directional carbon fiber reinforced polymer composites ﻿

(Wichita State University, 2011-05)
Composite materials have a wide range of applications in aerospace and automotive industries due to the advantage of their tailorability when manufacturing. These materials are manufactured near net shape but post-production ...
• #### Observing the effect of infill shapes on the tensile characteristics of 3D printed plastic parts ﻿

(Wichita State University, 2016-12)
The term 3D printing is becoming more of a household term every day. From hobby enthusiasts to industrial production, 3D printing technology has generated great progress in the product and development sector. The ability ...
• #### Obstacle adaptive approaches for distributed task assignment in autonomous mobile robots ﻿

(Wichita State University, 2009-07)
It has many challenges to assign a group of mobile robots to individual targets according to the specific constraints. In addition to the group behavior constraints (one-toone or one-to-many) of the task assignment, some ...
• #### Occupant injury assessment in an emergency landing condition for a vertical take-off and landing aircraft ﻿

(Wichita State University, 2020-12)
In the next few years, the aeronautical industry is poised to change in a way it has not for decades. There has been a rising interest in deploying Vertical Take-Off and Landing (VTOL) aircraft to serve on-demand ...
• #### Occupational sex segregation and its effect on income determination ﻿

(Wichita State University, 2007-12)
This study attempts to identify the factors that account for the unequal distribution of paid labor. Using the Current Population Survey March 2007, variables included in my saturated model (age, education, rural, southern ...
• #### Oil and gas-produced water treatment system for agricultural use in the state of Kansas ﻿

(Wichita State University, 2020-05)
Produced water (PW) is a term used to characterize water that is deposited over the course of a million years in the oil and gas reservoir rock formation and then flows to the surface along with the production of oil and ...
• #### On automatically classifying software code review feedback in the context of internal quality ﻿

(Wichita State University, 2017-07)
Recent empirical studies show that the practice of peer-code-review improves soft- ware quality. Therein, the quality is examined from the external perspective of reducing the defects/failures, i.e., bugs, in reviewed ...
• #### On convergence sets of formal power series ﻿

(Wichita State University, 2013-12)
In this thesis we consider the convergence sets of formal power series of the form f(z, t)=sigma infinity j=0 pj(z)tj, where pj(z) are polynomials. A subset E of the complex plane C is said to be a convergence set if there ...
• #### "On the cover of a Rolling Stone": a content analysis of gender representation in popular culture between 1967-2004 ﻿

(Wichita State University, 2006-05)
Compared to the large body of research on female gender roles, little research has focused on male gender representation. This study addresses male and female gender representation as portrayed on the cover of Rolling Stone ...
• #### On the energy efficiency of dynamic spectrum access in the ad-hoc Wireless LAN scenario ﻿

(Wichita State University, 2013-05)
Wireless data communications, especially to and from portable mobile devices, is one of the fastest growing paradigms in the field of computer communications. This fast paced growth of wireless communication devices is ...
• #### On the existence of central fans of capillary surfaces ﻿

(Wichita State University, 2013-05)
We prove that under some conditions, the central fans of capillary surfaces exist and are stable. We perturb the contact angle of a capillary surface for a bounded domain which is not necessarily symmetric, that has a ...
• #### On the improvement of permeability assessment of fibrous materials ﻿

(Wichita State University, 2010-05)
The focus of this work is to understand the current state of permeability measurement and prediction methods for fibrous, porous media and to suggest improvements. For this purpose the most widely used and accepted ...
• #### On the inverse gravimetry problem with minimal data ﻿

(Wichita State University, 2021-07)
In this dissertation we considered the inverse source problem $\Delta u = \mu,$ where lim $u (x) = 0$ as |x| goes to $\infty$ and $\mu$ is zero outside a bounded domain $\Omega$. The inverse problem of gravime- try is ...
• #### On the Kolmogorov-Arnold representation theorem for continuous functions ﻿

(Wichita State University, 2018-12)
In 1900 at the International Congress of Mathematicians in Paris, D. Hilbert posed 23 questions that later became known as Hilbert's 23 problems. Number 13 remained unresolved for over half a century until 1956 and 1957 ...
• #### On the Lévy-Steinitz Theorem ﻿

(Wichita State University, 2021-12)
This thesis is a further study of Riemann's Theorem of rearrangements of series. The theorem states: (1) If $\sum a_j$ is a conditionally convergent series of real numbers and a is a real number, then there is a rearrangement ...
• #### On the maxillomalar suture and the assessment of group affiliation ﻿

(Wichita State University, 2008-12)
