Identifying optimal educational parameters for augmentative and alternative communication users: Stakeholders' perspectives
(Wichita State University, 2021-12)Research involving parameters for designing and developing an appropriate educational program for students who use augmentative and alternative communication (AAC) in school settings is considered a relatively recent ... -
Multifunctional biomimetic scaffold with hydrogel for skin tissue engineering
(Wichita State University, 2021-12)Chronic wounds have been a global health threat over the past few decades, requiring urgent medical and research attention. The delayed wound-healing process may be attributed to obesity, microbial infection, aging, edema, ... -
The influence of social capital and community cultural wealth on college completion: Narratives of first generation adult learners
(Wichita State University, 2021-12)Adult learners and first generation students are less likely to persist to graduation than their traditional counterparts, however, some do manage to succeed in college and graduate (McCall et al., 2018; Means & Pyne, ... -
Waste not, want not: Household sentiment on food waste and the role of sustainable technologies
(Wichita State University, 2021-12)Researchers from the multidisciplinary field of human-computer-interaction (HCI) created a sub-field known as sustainable HCI to address environmental problems through technological interventions. The HCI community has ... -
Possible selves of college students experiencing depression: A shift in focus toward well-being
(Wichita State University, 2021-07)This study examined the possible selves, illness representations, psychological well-being, and experiences of depression among college students (N = 223) who completed an online survey. As hypothesized, students with ... -
Robotic refill friction stir spot welding for aerospace applications

Differentially private online learning algorithms for federated optimization
(Wichita State University, 2021-12)The exponential growth of the Internet from the last decade till the present has resulted in the generation of big data from billions of connected devices. Yet, big data are not readily available in many application ... -
Applications of tungsten sulfide/carbon nanocomposites in thirdgeneration solar cells and their techno-economic analysis
(Wichita State University, 2021-07)Being confronted with the energy crisis and environmental problems, the exploration of clean and renewable energy materials is urgently demanded. Dye-sensitized solar cells (DSSCs) have attracted widespread attention as ... -
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 to ... -
Perceptions of quality in e-learning for higher education
(Wichita State University, 2021-07)E-learning quality is a complex and multi-faceted issue. Some argue that the quality of e-learning should be judged by the same criteria and standards as face-to-face education. Others hold that conventional quality concepts ... -
Enhanced two-phase cooling using bi-particle-size sintered particle evaporator with distributed liquid supply capillary wicks
(Wichita State University, 2021-08)Liquid-vapor, phase-change heat transfer using wicks can provide reliable and high heat flux cooling capability, especially in microgravity applications. However, the maximum heat removal capacity, also known as Critical ... -
Improving treatment-seeking attitudes by reducing treatment seeking stigma via a web-based program
(Wichita State University, 2021-07)Despite the potential benefits of mental health treatment, a substantial proportion of those with a diagnosable mental health disorder do not seek treatment, and treatment-seeking stigma has been cited as a major reason. ... -
Positive (p, n)-intermediate scalar curvature and Gromov-Lawson cobordism
