- ItemReconfigurable and compact modular polynomial multiplier in Galois field for the security of IoT(Lethbridge, Alta. : University of Lethbridge, Dept. of Mathematics and Computer Science, 2025) Haroon, Fariha; University of Lethbridge. Faculty of Arts and Science; Li, HuaThe rise of the Internet of Things (IoT) has intensified the need for secure, low-power cryptographic hardware capable of operating efficiently in constrained environments. This thesis presents the design and implementation of reconfigurable and compact modular polynomial multipliers over Galois Fields (GF), specifically tailored for the security demands of IoT devices. Leveraging polynomial basis arithmetic in GF(2m), the proposed designs emphasize hardware efficiency, adaptability, and cryptographic robustness for Elliptic Curve Cryptography (ECC) applications. The proposed multipliers were synthesized and validated on multiple FPGA platforms including Spartan-7, Zynq UltraScale+, and Artix-7 using the AMD Xilinx Vivado toolchain. The Karatsuba reconfigurable multiplier achieved the best area-delay product (ADP) across platforms. Analytical and experimental comparisons confirm that the reconfigurable approaches significantly outperform conventional designs in terms of efficiency and scalability. This research provides a practical and versatile foundation for cryptographic accelerators in future low-power and high-security IoT systems.
- ItemAs we hold space, together: Cherokee pottery and our enduring presence(Lethbridge, Alta. : University of Lethbridge, Dept. of Indigenous Studies, 2025-09-11) Tiger, Yvonne N.; University of Lethbridge. Faculty of Arts and Science; Laurendeau, JasonThis dissertation considers earthwork mounds and the contemporary history of Cherokee Nation of Oklahoma pottery and its production both as land(scape) and an expression of our relationships to land and place. My work is an embodied inquiry of these the relationships between physical Indigenous land and concepts of place specificity as expressed through and imbued in pottery and ancient earthworks. Within this work I also argue that the creation of ancient pottery exemplifies the ways in which our ancestors utilized technological-ecological knowledge and transferred this knowledge to successive generations. My work is guided by my adherence to a critical Indigenous citational practice. It is my position that Indigenous art history must make ‘place’ an imperative part of our narratives and discourse about art and makers as a means of countering mainstream narratives about us.
- ItemImpact of interest rates and private wealth on labor supply: a study on G7 countries(Lethbridge, Alta. : University of Lethbridge, Dept. of Economics, 2025) Razzaque, Qudrat E.; University of Lethbridge. Faculty of Arts and Science; Darku, AlexanderThis study examines the impact of interest rates and private wealth on labor supply across the G7 countries using data from 1971 to 2020. It uses a panel data analysis to explore how the changes of these variables influence labor supply, with a particular focus on substitution effect¬ — where labor supply increases as the interest rates rise — and income effects — where wealth accumulation reduces the labor supply. The study uses a Representative Agent New Keynesian (RANK) model to frame the theoretical discourse on the labor supply decisions. In the empirical analysis we considered the possibility of structural break and implemented diagnostic checks for it. The findings postulate insightful results, such as the dominance of the substitution effect in the case of interest rates, and the dominance of income effect when the interest rate was persistently high. Although, there is a statistically significant impact of these variables on the labor supply, the magnitude of these impacts remains modest
- ItemParables of the lovers: the hermeneutics of divine love in medieval Islamic mysticism(Lethbridge, Alta. : University of Lethbridge, Dept. of History and Religion, 2025) Ascione, Cassidy M.; University of Lethbridge. Faculty of Arts and Science; Khalil, AtifThrough a hermeneutic analysis of medieval Islamic texts, the thesis examines the development of ideas about Divine love––its ontological origin, nature, and telos––in Sufism, with a focus on the teachings of four luminaries within the mystical tradition: Abu Hamid al-Ghazali (d. 505/1111), Ahmad al-Ghazali (d. 520/1126), Ibn ‘Arabi (d. 638/1240), and Jalal al-Din Rumi (d. 672/1273). It begins with a brief study of the development in the philosophy of love in Sufi thought up to the classical period in which these four figures lived. Love is shown to be central to the mystical path, even though its precise nature, as evidenced in the writings of these mystics, was interpreted with some differences. The thesis explores some of these varying nuances through a microanalytic, comparative study of their writings. It is shown that Rumi and Ahmad al-Ghazali inclined towards a more intoxicated approach, evidenced in the language of love, as found in their poetry, while Abu Hamid’s inclination was towards a more sober practice. Ibn ‘Arabi adopted a middle ground between the other writers, advocating an approach which lay in between the extremes of sobriety and intoxication. In the end, however, common motifs, ideas, and themes, outweighed the differences in their philosophies of love.
- ItemGoing beyond the dyadic paradigm: the dynamics of social play and brain development(Lethbridge, Alta. : University of Lethbridge, Dept. of Neuroscience, 2025) Ham, Jackson R.; University of Lethbridge. Faculty of Arts and Science; Pellis, Sergio M.Rough-and-tumble play (RTP) during the juvenile period is critical for developing social competency and some of its associated neural underpinnings in the medial prefrontal cortex (mPFC), yet little is known about how individual variability in play experiences affects development. This thesis investigates whether rats show preferences for specific play partners, what factors influence these choices, and how differences in RTP contribute to behavioral and neural outcomes. Using group play paradigms, I found that rats form partner preferences based on factors such as familiarity, play style, and strain; however, these preferences depend on social context. Indeed, among familiar group members, not all individuals are equally preferred, leading to unequal RTP experiences. The effects of juvenile variability in RTP was assessed by manipulating juvenile experiences and by tracking the life history of individuals reared in groups. Rats reared with a higher-playing strain engaged in less RTP and turn taking than those reared with same-strain partners and later exhibited social deficits and altered mPFC neuron morphology. Similarly, when reared in groups, individuals that naturally engaged in less role reversals during RTP showed impaired social competence and atypical mPFC development. These findings suggest that some rats fail to benefit from RTP. A possible reason for such failure is that early-life influences may impair rat sociability. To explore this, I used neonatal isolation as a model of early life adversity (ELA). ELA did not alter role reversals with familiar partners but reduced both RTP frequency and role reversals with unfamiliar individuals, suggesting that pre-juvenile experiences can indeed impair the mechanisms that maximize the benefits gained from juvenile RTP. Together, these results show that rats preferentially play with certain partners, and this can influence the value of experiences derived from RTP, which combined with individual differences in play cooperation, can shape developmental outcomes.
