Nano scaled antennas with metamaterial versus centimeter/millimeter scaled antennas without metamaterial
(Wichita State University, 2016-07)This paper studies the effects of liquid crystal (e.g, 4-Cyano-4'-pentylbiphenyl [5CB]) as a substrate on the performance of a nano-antenna at very high frequency, 0.1 THz to 10 THz. Also, since the size and shape of the ... -
Nanocomposites and graphene oxide thin film coatings on the surface of fiber reinforced composites for enhanced flame retardancy
(Wichita State University, 2013-05)The polymer matrix system of thermoset fiber-reinforced composites helps protect the high modulus and strength fibers from the adverse environment and also transfer the load to reinforced fibers. However, when subjected ... -
Nanoscale reinforced laminated nanocomposite materials systems for high-performance structural applications
(Wichita State University, 2022-12)Polymer-based laminated composite materials are widely used in many industries due to their superior mechanical properties. The main disadvantage of using composites is their delamination failure that occurs due to poor ... -
A narrative inquiry of rural, low-income, single mothers’ aspirations for their children
(Wichita State University, 2010-05)This narrative inquiry focused on what four low-SES single mothers had to say about their aspirations for and support systems they have for their children. Discussions with the mothers involved a mix of topics. The four ... -
A narrative inquiry: Eight urban high school students share about their lives and experiences in school
(Wichita State University, 2008-05)This qualitative study focused on what eight urban high school students from varying backgrounds had to say about their lives and experiences in school. Discussions with the students involved multifarious topics such as ... -
Nationalism and postcolonial feminism: A literary approach to Palestinian women’s resistance
(Wichita State University, 2021-05)In this thesis, I examine Palestinian women writers and their contributions to resistance writing. I argue that contemporary Palestinian women's writings significantly contribute to social justice movements concerned ... -
Native American colonization
(Wichita State University, 2022-05)The United States launched a multi-pronged genocide against the Native Americans in order to achieve Manifest Destiny. It was not political manipulation nor economic dependency nor cultural genocide alone that forced the ... -
Naturalistic walking and typing on a smartwatch: a comparison of input methods
(Wichita State University, 2019-05)Despite widespread development within the technology industry, smartwatches have historically been unsuccessful in their sales worldwide. Several factors have contributed to the poor sales of smartwatches, namely the lack ... -
Navigating nuance in native bee responses to grassland restoration management: A multi-ecoregional approach in the Great Plains
(Wichita State University, 2019-12)Habitat fragmentation due to agricultural intensification leads to losses of biodiversity and ecosystem services such as pollination. Wild bee declines pose a serious threat to pollination stability and are expected to ... -
Navigating the education bureaucracy: How principals make sense of distributed leadership in practice
(Wichita State University, 2019-12)Distributed leadership has been accepted as the term used to describe various forms of shared or collaborative leadership practices in schools (Harris, 2013; Leithwood & Mascall, 2008). Principals are charged with enacting ... -
Necessary "others" in American public schools: Stories of students with juvenile records
(Wichita State University, 2018-05)For decades federal and state agencies have reformed criminal and juvenile justice laws to reduce recidivism rates in the United States. Based on successes adult populations have experienced exiting the system using a ... -
The need for professional writing programs in higher education: a modest proposal
(2007-05)The purpose of this thesis is to explain why a professional writing curriculum would be an invaluable program to institute in American universities across the country. So many people think that because we all learn to read ... -
Needs finding to assess wayfinding and navigation challenges encountered by people with limited mobility
(Wichita State University, 2022-07)Currently, personal navigational systems are largely reserved for outdoor travel using GPS technologies on smartphone applications. While smartphones are approaching ubiquity, navigational systems have lacked consideration ... -
Neuroadaptive observer design for spacecraft attitude control and formation attitude synchronization
(Wichita State University, 2020-12)Spacecraft attitude-tracking control problems require uncertainties and disturbances- rejecting controllers to perform well in practical scenarios. The objective of this research is to design an adaptive controller that ... -
Neutrino detector design, attenuation studies, and testing for the νSol project
(Wichita State University, 2020-05)In order to further work on the Sol project funded through a NASA Phase II NIAC grant, I have performed detailed simulations on the effect of attenuation length on the performance of the Sol solar neutrino probe using ... -
A new alternate routing scheme with endpoint admission control for low call loss probability in VoIP network
(2006-07)Call admission control (CAC) extends the capabilities of Quality of service (QoS) tools which protect voice traffic from the negative effects of other voice traffic. It does not allow oversubscription of a Voice over ... -
