This study explores the enhancement of Kevlar fabric’s ballistic performance through impregnation with Shear Thickening Fluid (STF) for potential application in soft body armor. The experimental approach often fails to elucidate mechanical phenomena critical for the development of lightweight and high-strength body armor designs. To address this limitation, the finite element method, specifically using ANSYS/LS-DYNA R.13, was employed for a comprehensive analysis. The simulation aimed to evaluate the impact of STF on Kevlar fabric by assessing projectile velocity, force exerted by the projectile onto the fabric, displacement, stress distribution, and fabric failure mechanisms. Kevlar yarn was modeled as a shell …

Journal of Mechanical Engineering Science and Technology (JMEST)

The TiO2 film is immersed in a graphite oxide solution, preparing it for thermal reduction, which converts the graphite oxide to reduced graphene oxide (rGO). This process produces rGO hybrid TiO2 photoanodes for dye-sensitized solar cells (DSSC). rGO in the TiO2 structure prevents electron recombination and improves overall efficiency. The main advantage of this method is its ability to prevent loss of rGO during the sintering process, which is a common problem with other methods. The study investigated heating temperatures ranging between 300˚C, 350˚C, 400˚C, 450˚C, and 500˚C to determine optimal conditions. The presence of rGO in the photoanode structure …

Grievability And The Contingency Of Life Value In Twenty-First-Century Science Fiction, Emily A. Reiff Jul 2024

Grievability And The Contingency Of Life Value In Twenty-First-Century Science Fiction, Emily A. Reiff

English Language and Literature ETDs

Using Judith Butler’s framework of grievability, this dissertation explores twenty-first-century science fiction by British, Irish, and Caribbean authors whose novels grapple with legacies of colonialism and imperialism that relied on dehumanization and subjugation. Beginning with Sarah Maria Griffin’s Spare and Found Parts (2016), chapter one explores neocolonial rationales—purportedly based on health—which recreate colonial divisions of class and labor and enforce systems of diminishing grievability in a post-apocalyptic Irish context. Chapter two contends that Kazuo Ishiguro’s Klara and the Sun (2021) illustrates the danger inherent to value systems that center “normative” embodiment in worlds that reconfigure hypercapacitated human beings as the …

(Dis)Connecting Incommensurable Relationalities: Aesthetics Of Desirable Citizenship & Interethnic Solidarity In Vietnamese/American Diasporic Media, Anh A. T. Nguyen Jul 2024

(Dis)Connecting Incommensurable Relationalities: Aesthetics Of Desirable Citizenship & Interethnic Solidarity In Vietnamese/American Diasporic Media, Anh A. T. Nguyen

Communication ETDs

Employing critical diasporic rhetoric to articulate the pull and push glimmer of essentialist and nationalistic agendas of constructing Vietnamese diasporic subjectivities, I elucidate the complicated structure of diasporic nationalism that gives shape to ambiguities, paradoxes, and contradictions of Vietnamese diasporic withdrawal and regroupment in interethnic politics. Through three case studies explicating Vietnamese diasporic responses to the Chinese virus rhetorics, the appearance of the South Vietnamese flag on January 6 Capitol grounds, and the Atlanta shootings in Saigon Broadcasting Television Networks (SBTN), I highlight how Vietnamese diasporic authorities perform and enact citizenships of becoming desirable, which elevates oppressive forces of ideological …

Interpreting Ppv And Npv Of Diagnostic Tests With Uncertain Prevalence, Yakov Ben-Haim, Clifford C Dacso Jul 2024

Interpreting Ppv And Npv Of Diagnostic Tests With Uncertain Prevalence, Yakov Ben-Haim, Clifford C Dacso

Faculty, Staff and Students Publications

OBJECTIVE: Medical decision-making is often uncertain. The positive predictive value (PPV) and negative predictive value (NPV) are conditional probabilities characterizing diagnostic tests and assessing diagnostic interventions in clinical medicine and epidemiology. The PPV is the probability that a patient has a specified disease, given a positive test result for that disease. The NPV is the probability that a patient does not have the disease, given a negative test result for that disease. Both values depend on disease incidence or prevalence, which may be highly uncertain for unfamiliar diseases, epidemics, etc. Probability distributions for this uncertainty are usually unavailable. We develop …

Short-Time Fourier Transform And Superoscillations, Daniel Alpay, Antonino De Martino, Kamal Diki, Daniele C. Struppa Jul 2024

Short-Time Fourier Transform And Superoscillations, Daniel Alpay, Antonino De Martino, Kamal Diki, Daniele C. Struppa

Mathematics, Physics, and Computer Science Faculty Articles and Research

In this paper we investigate new results on the theory of superoscillations using time-frequency analysis tools and techniques such as the short-time Fourier transform (STFT) and the Zak transform. We start by studying how the short-time Fourier transform acts on superoscillation sequences. We then apply the supershift property to prove that the short-time Fourier transform preserves the superoscillatory behavior by taking the limit. It turns out that these computations lead to interesting connections with various features of time-frequency analysis such as Gabor spaces, Gabor kernels, Gabor frames, 2D-complex Hermite polynomials, and polyanalytic functions. We treat different cases depending on the …

Incomplete Faces Do But Masked Faces Do Not Affect Mind Perception, Farid Pazhoohi, Keina Aoki, Alan Kingstone Jul 2024

Incomplete Faces Do But Masked Faces Do Not Affect Mind Perception, Farid Pazhoohi, Keina Aoki, Alan Kingstone

School of Psychology

The human face plays a critical role in how we perceive the minds of others. The current research across two studies explored whether face masks also impact mind perception, with the expectation that they lead to lower attributions of agency and experience to individuals, making them seem less mentally capable due to their association with reduced facial expression perception and impaired communication. In the first study, participants’ ratings of masked and unmasked faces for agency and experience did not yield significant differences, suggesting that wearing a face mask does not affect the perception of the mind. To explore whether these …
