Implications Of The Mind’S Active Participation In The Formation Of Perception, Maikel Adel Samy Michael

Theses and Dissertations

The mind-body problem, particularly the issue of qualia, remains a fundamental challenge in understanding the nature of the mind and its relation to the body. In this thesis I argue that the problem is epistemic, stemming from how we perceive and know ourselves as physical and mental beings. This argument will be explored through the respective of idealisms proposed by George Berkeley and Immanuel Kant. Berkeley's idealism suggests that reality is rooted in perception, offering a major steppingstone by demonstrating the major role perception plays in understanding and acquiring knowledge. Kant contributes by asserting that the "thing-in-itself" is beyond our …

Ways Of Living And Knowing, Reem El Hassan Mohamed

Theses and Dissertations

After decades of sedentarization, the Muzeina tribe in South Sinai now has new generations born into sedentary lifestyles, never experiencing nomadism like their ancestors once did. This shift has impacted their knowledge system, traditionally shaped by interactions and kinship with nature. Exposure to social media is influencing younger generations' ways of living, raising the older generations’ concerns about their Bedouin identity. Despite being one of the largest tribes in South Sinai, the Muzeina are rarely represented in literature.

This ethnography explores the impact of sedentarization and contextual developments on the Muzeina's knowledge system, inherited from their ancestors. Muzeina’s relationship, and …

A Tragedy Of Incommensurability: Indigenous Rights And The Limits Of Human Rights Law, Zeina Ali

Theses and Dissertations

This thesis explores the tragedy of incommensurability between indigenous rights and international human rights law. Despite the emergence of frameworks like the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP), indigenous calls for sovereignty remain fundamentally unintelligible within a liberal order structured to preserve settler-state legitimacy. Tracing the historical and theoretical evolution of indigenous advocacy, this study critiques the strategic shift from demands for self-determination to claims of cultural rights. It argues that this shift offers no real alternative: self-determination and cultural rights are functionally equivalent, as both are ultimately filtered through legal and political frameworks that cannot …

The Sealed Palace: How Direct Access To The Supreme Constitutional Court Can Bridge The Gaps In Constitutional Review In Egypt, Ahmed Sameh Fahmi

Theses and Dissertations

This thesis examines the limitations of Egypt’s current constitutional review system and argues for the introduction of a direct access mechanism to the Supreme Constitutional Court (SCC). Under Egypt’s centralized model of judicial review, individuals are restricted to indirect access through ordinary courts, which has resulted in significant procedural and substantive inefficiencies. The referral-based mechanism of judicial review of legislation has caused delays in adjudicating constitutional claims, the insulation of certain laws from review, legislative omissions, and excessive gatekeeping by lower courts. Through a comparative analysis of direct access models in Colombia, Germany, Turkey, and South Africa, the thesis identifies …

Quantum-Chemical Modeling Of Mechanisms And Selectivity In Open-Shell Organometallic Reactions, Michael T. Davenport

Theses and Dissertations

Quantum mechanical calculations have emerged as a powerful approach for directly evaluating reaction mechanisms and selectivity in transition metal-ligand complexes involving organometallic intermediates. Density functional theory (DFT) quantum mechanical methods enable the generation of potential energy surfaces and structures that define reaction mechanisms and allow for the evaluation of selectivity through statistical transition state theory. However, in certain cases, it is necessary to go beyond statistical treatments and incorporate atomic motion through molecular dynamics simulations. Additionally, many transition metal-mediated reactions involve unpaired electrons and spin state crossings. This dissertation focuses on the application of DFT-derived potential energy surfaces and molecular …

Rapid Beamformer Weight Calibration Update Method For The Advanced L-Band Phased Array Camera For Astronomy (Alpaca), Kayla Lyman Ward

Theses and Dissertations

The Advanced L-Band Phased Array Camera for Astronomy (ALPACA) is a phased array feed instrument designed for the Green Bank Telescope. It is capable of producing 40 real-time beams on the sky, widening the telescope's field of view and significantly increasing survey speed. ALPACA employs an RF-over-fiber (RFoF) signal transport system from the phased array feed front end to the digital backend. This RFoF link is expected to introduce phase delays and changes in gain through out the course of an observation, invalidating the beamformer weights previously calculated. This work presents rapid beamformer weight calibration updates for ALPACA, a method …

Wireless Bus Interconnects For Enhanced Small Satellite System Integration And Reliability, Adam Fifth

Theses and Dissertations

In small satellite engineering systems, managing numerous subsystem interconnections presents a significant design challenge directly impacting mission success. Traditional CubeSat subsystems rely on the PC/104 header system for integration, which consumes substantial board area and adds considerable vertical spacing between subsystems. This rigid wired architecture severely restricts subsystem density, complicates assembly and testing procedures, and prevents reconfiguration of interconnections after deployment. This dissertation presents a transformative approach to satellite subsystem integration by developing and validating a Bluetooth Low Energy (BLE) wireless interconnect system replacing traditional wired connections. This research addresses wireless implementation challenges. Through iterative prototype development, I demonstrate a …

Hierarchy Viz: A Visual Analytics Framework For Visualizing Hierarchical Data Using Machine Learning, Vinay Kumar Uppalapati

Theses and Dissertations

Automated visualization systems aim to generate visualizations directly from raw data with minimal user inputs. However, while existing systems focus on data visualizations mainly using line charts and scatter plots to explore the data patterns, they struggle with hierarchical data representation where data relationship is essential. Hierarchical visualization, crucial for understanding multi-level relationships, typically requires users to manually define hierarchies and have expertise in visualization tools to create meaningful representations. This makes the process complex, time-consuming, and reliant on domain knowledge. To address this, we propose HierarchyViz, an automated system that detects multiple hierarchies in raw datasets and generates intuitive …

Multi-Field Quantum Conference Key Agreement Using An Integrated Photonic Green Machine, Benjamin J. Fisher

Theses and Dissertations

Quantum Conference Key Agreement (QCKA) enables a group of users to generate a shared secret key, which reduces the latency and equipment overhead of establishing multiple Quantum Key Distribution (QKD) links. Conventional QCKA protocols send a multi-photon entangled state from one user to others and a key is generated only when all photons are detected, which is inefficient at high loss and opens side-channels at the receiver side. Here, we overcome this barrier through a multi-field QCKA protocol enabled by designing, fabricating, and testing an integrated photonic Green Machine that implements an eight-mode Hadamard unitary transformation through a beam-splitter network. …

Exploring Consequences Of The Double Empathy Problem Across The Autistic Trait Spectrum: First Person Accounts, Cammy C. Peck

Theses and Dissertations

Historically, individuals on the autism spectrum were believed to have deficits in empathy. However, recent research suggests that empathy-related issues occur on both sides of the communication dynamic. This concept known as the Double Empathy Problem (DEP), posits that the perceived lack of empathy is not exclusive to autistic individuals; rather, neurotypical (NT) individuals also experience difficulty empathizing with autistic individuals (Milton, 2012). Milton et al. (2022) describes this as a "breakdown in mutual understanding". Such mutual misunderstanding can have adverse consequences for both autistic and neurotypical individuals. To our knowledge, no studies have directly examined these consequences in relation …

How Transitioning Autistic Adults Consciously Perform Neurotypical Communication, Makenna J. Allred

Theses and Dissertations

Using semi-structured interviews this research explored the experiences of transitioning autistic adults with online communication. Participants shared information about navigating online communication, highlighting specific challenges such as interpreting tone and sarcasm, managing unspoken social norms, like emoji use, and responding to ambiguous or unexpected interactions. Participants shared that misunderstandings do occur in their online communication and how they recognize those miscommunications and strategize around preventing and mitigating them. These findings reveal that while computer-mediated communication offers opportunities for connection, it also presents unique obstacles that can exacerbate feelings of frustration due to miscommunications or misunderstandings. To prevent these social frictions …

Semitic Root Encoding: Tokenization Based On The Templatic Morphology Of Semitic Languages In Nmt, Brendan T. Hatch

Theses and Dissertations

The morphological structure of Semitic languages like Arabic and Hebrew is based on non-concatenative roots and templates. This complex word structure used by humans is obscured to neural models that use traditional tokenization algorithms. In this work, I present and evaluate Semitic Root Encoding (SRE), a tokenization method that represents Semitic words with distinct root and template stem tokens, and apply it to neural machine translation (NMT). I evaluate whether tokenization with the SRE method leads to increases in translation quality, whether it allows NMT models to hypothesize unseen word forms needed at inference, and how impervious resulting NMT models …
