From Aspiration To Obligation: A Contractual Sustainability Framework For The Egyptian Construction Industry, Salma Ali

Theses and Dissertations

The construction industry is responsible for approximately 40% of global energy consumption and 35% of total waste generation, making it one of the most significant contributors to the global sustainability challenge. In Egypt, that challenge takes a specific contractual form. Egypt’s construction sector contributes approximately 23% of national energy consumption, yet the survey findings reveal that 63.5% of construction professionals report that sustainability clauses rarely or never appear in contracts, and only 11.5% confirm the presence of enforceable provisions with measurable targets. This gap is structural rather than attitudinal. Competitive procurement penalises voluntary sustainability investment, and without contractual obligation, awareness …

The Informal Impact Of The Headscarf Ban On Veiled Students’ Everyday University Experiences In Paris, Farah K. Lotfy

Theses and Dissertations

This study examines the informal impact of the 2004 headscarf ban on the everyday university experiences of veiled students in Paris. Although the ban applies formally to public schools rather than universities, the wider social climate surrounding laïcité and the veil continues to influence how veiled students experience visibility, belonging, and participation in higher education.

Using a qualitative approach based primarily on semi-structured interviews, supported by informal observations conducted within university spaces in Paris, the study explores how exclusion is experienced through stereotypes, scrutiny, social discomfort, self-monitoring, and anticipation of discrimination rather than through formal university policy. The research focuses …

Engineering Nanoelectrocatalytic Systems For Co2 And Nitrate Conversion Into Value-Added Chemicals, Abdelrahman Mohamed Abdelmohsen

Theses and Dissertations

The thesis addresses two major related environmental crises: nitrate pollution of water systems and the ever-increasing levels of atmospheric carbon dioxide. Both challenges are closely linked to anthropogenic disturbance of nitrogen and carbon cycles and require sustainable, energy efficient mitigation techniques. In this study, we investigate electrochemical conversion routes as a unified approach to convert these pollutants into value-added compounds: ammonia (NH3) via nitrate reduction (NO3-RR) and ethylene (C2H4) via carbon dioxide reduction (CO2RR). The first half of this work deals with the design and engineering of Cu-Zn alloy electrocatalysts for efficient NO3-RR. Tuning the alloy composition and surface nanostructure …

Flexible-Mode Multi-Skilled Resource-Constrained Project Scheduling Problem With Setup Times: Application In The Oil And Gas Industry, Safinaz M. El Dawody

Theses and Dissertations

Turnaround maintenance (TAM) in the petroleum refining sector requires coordinating geographically dispersed project portfolios under stringent resource, schedule, and budget constraints. Conventional scheduling models treat tasks in isolation, failing to account for shared resources, crew fatigue, or inter-site transit. To bridge this gap, this study introduces and empirically validates a Flexible-Mode Multi-Skilled Resource-Constrained Project Scheduling Problem with Setup Times (FM-MS-RCPSP-ST). Applied to a real-world portfolio of 76 TAM projects across five governorates in Egypt, the framework is operationalized through an 11-stage pipeline integrating NSGA-II multi-objective optimization, GIS-based routing, and 500-trial Monte Carlo disruption simulations.

Results demonstrate that incorporating mandatory crew-rest …

The Effect Of Mwcnt-Oil Impregnation Of Sintered Components On Their Wear And Corrosion Resistance, Maha Khaled Abdelfadeel

Theses and Dissertations

Powder Metallurgy (PM) offers an advantageous route for manufacturing complex and near net-shape components. Their inherent interconnected porosity that promotes the action of self lubrication compromises their structural integrity by creating pathways for corrosion and excessive wear. This research investigates the efficacy of Multi-Walled Carbon Nanotubes (MWCNTs) as a nano additive within the impregnating base oil (SN-150 base oil). An experimental matrix was designed to evaluate the influence of MWCNTs with different concentrations of 0.05, 0.1, and 0.2 wt.% and ultrasonic dispersion with varying sonication times of 30 and 60 minutes on the tribological and electrochemical performance of sintered steel …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

We report the detection of a set of new near-infrared emission features between 3.5 and 5.2 μm in JWST/NIRSpec observations of Tc 1, the planetary nebula known for displaying the cleanest and most prominent mid-infrared cosmic fullerene spectrum. These broad features share the same spatial distribution as the well-known C₆₀ and C₇₀ mid-infrared emission bands, peaking in an asymmetric ring approximately 5″–6″ from the central star. Through comparison with new anharmonic quantum chemical calculations, we demonstrate that these features arise from C₆₀ combination bands, marking their first detection in an astrophysical environment. The total energy radiated …

The Kashmir Conflict After The Abrogation Of Articles 370 And 35a Of The Indian Constitution: Geopolitical Dynamics And Human Security Implications, Rizwan Ali

Dissertations and Theses

The abrogation of Article 370 of the Indian Constitution on August 5, 2019, revoked the special autonomous status of Jammu and Kashmir (J&K) under the Indian administration. It further bifurcated it into two Union Territories under central Indian control. The move came amid a severe security lockdown and communication blackout that lasted for months. It was followed by instrumental legal, social, and economic developments that directly affected the area’s disputed status and the human rights of its residents. This research examines the geopolitical and human security implications of the abrogation and subsequent developments through a qualitative, analytical design, integrating Edward …

This paper presents the intellectual and aesthetic journey of creating an innovative makerspace within a technology education context and explains how this work embodies a sustainable model for training future technology educators. Our approach was informed by the …

Using Social Return On Investment To Evaluate Services That Support The Health Of People Experiencing Homelessness In Australia: A Scoping Review, Cate Mckenna, Christopher Rouen, Mary O'Loughlin

Research outputs 2022 to 2026

The increasing demand for homelessness services in Australia highlights the need for robust evaluation methodologies to assess their social impact. Traditional economic evaluation methods often struggle to capture the intangible social and health outcomes associated with homelessness. Social return on investment (SROI), an outcomes-based framework driven by stakeholders, offers a flexible and comprehensive approach to measuring social, economic and environmental impacts. This scoping review examines the application of SROI in evaluating services that support the health of people experiencing or at risk of homelessness in Australia. A total of 25 reports from grey literature (2010-2023) were reviewed. The findings reveal …

Self-Healing Qos Queue Management, Anonymous

Defensive Publications Series

A self-healing quality of service (QoS) queue management system and method are disclosed for a multi-service network node. Ingress traffic is classified by a class of service (COS) map and forwarded by a scheduler to a normal queue set of per-service egress queues. A queue monitor aggregates per-queue telemetry, including credit accumulation statistics, drops, and depth, and feeds the telemetry to a self mapping correction engine over a feedback path. The correction engine distinguishes a queue freeze from transient congestion by detecting that a queue has available credits yet is not draining, and in response rebinds the affected service to …

Robust Overnight Heart-Rate-Variability Estimation Independent Of Sleep/Wake Staging, For Movement-Disordered Sleep (Rem Sleep Behavior Disorder / Parkinson's), Gerard Ziemski

Defensive Publications Series

Consumer wearables compute overnight heart-rate variability (HRV) — a widely used "readiness" or recovery signal — by first staging sleep from body movement and then aggregating HRV over the epochs labeled as sleep. In people with movement-disordered sleep, paradigmatically REM sleep behavior disorder (RBD), which is strongly associated with Parkinson's disease, this fails: dream-enactment movement during REM is misclassified as wakefulness, so valid cardiac data is discarded and the resulting figure is unreliable. This disclosure describes a method that computes the nightly HRV figure over the full in-bed window — without conditioning on the device's sleep/wake or sleep-stage classification — …

Synchronized Multi-Line Digital Signal Generation Using Plural Independent Software-Triggered Serializer Peripherals With Open-Loop Fixed Start-Skew Compensation, Gerard Ziemski

Defensive Publications Series

A method is disclosed for generating two or more time-aligned digital output signals — for example a differential pair such as the USB D- / D+ data lines, or more generally any paired, differential, multi-phase, polyphase, quadrature, or multi-channel synchronized output — on a microcontroller or system-on-chip that provides plural independent hardware serializer peripherals (such as two or more SPI master transmit/MOSI engines) but provides no single peripheral and no dedicated hardware capable of driving the desired multi-line signal directly.

Each output line is assigned its own serializer and preloaded with a precomputed bitstream. The serializers are started by back-to-back …

Dynamic Video Resolution For Background Playback, Daniel Vik, Jugal Manjeshwar

Defensive Publications Series

This document describes techniques for a context-aware media scaling system that dynamically adjusts the resolution for video playback on devices (e.g., resource-constrained devices such as smart televisions) based on the current state and navigational context of a user interface (UI). The system determines the current state by actively tracking an application’s view context or page identifier (ID) to detect navigational transitions between a primary viewing UI (e.g., a “Watch” page) and a secondary navigational UI (e.g., for browsing content). The system maps the current state to a specific resolution policy. For example, for a transition from the primary viewing UI …

Calibration Of A Quantum Random Number Generator System Using Machine Learning, Ashish Kundu, Ramana Kompella, Peng Zhao, Eneet Kaur

Defensive Publications Series

Disclosed are techniques for calibrating a quantum random number generator (QRNG) system using machine learning to detect noise, drift, and entropy degradation across devices and the QRNG pipeline. One or more models evaluate device data, entropy quality, and system conditions to determine whether recalibration is needed, which devices should be recalibrated, and when recalibration should occur. The techniques may also support predictive recalibration and calibration planning to improve entropy quality and overall QRNG reliability.

Autonomous Multi-Agent System For Declarative Data Center Lifecycle Management, Ananya Simlai, Niccolò Cascarano

Defensive Publications Series

Conventional data center management can involve manual workflows or static declarative systems that may not effectively adapt to real-time conflicts or complex events, potentially resulting in unpredictable deployment timelines and increased operational risk. Systems and methods are described that can utilize a multi-agent ecosystem for managing data center resources. In such a system, specialized, autonomous software agents can communicate and negotiate with one another through a medium such as an asynchronous fabric to interpret high-level declarative goals. The agents may autonomously orchestrate complex actions, resolve resource conflicts, and adapt to changing conditions. This approach can improve operational resilience and agility …

La Conceptualisation Du Temps À Travers Les Métaphores Dans Le Parler De Zayan : Approche Cognitive, Amenzou El Mostafa, Brahim Oumeraouch

Journal of Amazigh Studies

L'analyse des expressions métaphoriques du temps dans le parler des Zayan révèle une utilisation récurrente de métaphores conceptuelles qui reflètent la perception du temps dans cette culture. Les expressions métaphoriques telles que « le temps coule » sont largement utilisées pour décrire la continuité et l'irréversibilité du temps, tandis que celles comme « ne gaspille pas l’argent » soulignent sa valeur et sa gestion. En examinant ces expressions à travers les postulats de la théorie de Lakoff (1980), nous observons que les schémas conceptuels associés au temps reflètent deux visions distinctes : une conception dynamique, où le temps est vu …

Indigeneity In The Diaspora: Amazigh Women In The United States, Heide Castaneda

Journal of Amazigh Studies

As people migrate elsewhere, they create new forms of solidarity and citizenship through articulations of their Indigenous identity. The activities and identity formations of migrant Imazighen have long been integral to the Amazigh movement, often producing and propelling forward ideas and practices that influence politics in their North African homelands. At the same time, migration is a key driver of shifts in gender roles and identity. The gendered dimension of Indigenous experience remains largely underexplored and is the subject of this article. Amazigh women, like other Indigenous women around the globe, are frequently portrayed as guardians of cultural and linguistic …

Reframing Kabyle Resistance In Marc Garanger's Femmes Algériennes 1960, Lea Wong

Journal of Amazigh Studies

This article examines the identity photographs taken by Marc Garanger as a site of Kabyle women’s resistance in the Algerian War. Over the course of 1960, Garanger moved between various wartime displacement camps across Kabylia, photographing indigenous people for the production of identity cards––a crucial from of colonial population control. Since its publication, Garanger’s Femmes algériennes has become an ambiguous symbol of resistance in the Algerian War, largely due to the subjects’ perceived antagonistic posture and gaze. This article takes a forensic approach to analyzing Kabyle women’s wartime adornment, uncovering a new framework for conceptualizing Algerian women’s agency grounded in …

Representations Of Women Safeguarding Living Cultural Heritage For The Future In 21st Century Kabyle Cinema, Sheila Petty

Journal of Amazigh Studies

This article examines cinematic representations of how some Kabyle women relate to and shape claims to Amazigh (Kabyle) land, language, tangible and intangible cultural heritage; how they navigate and safeguard cultural memory; and how this is depicted in three Kabyle films: La Langue de Zahra/ Zahra’s Mother Tongue (Fatima Sissani, France/Algeria, 2011); Nnuba (Sonia At Qasi-Kessi, Algeria, 2019; and Azar/Racine/Root (Malik Bourkache Daoud, Algeria, 2023). The article also probes how the filmmakers use tangible cultural heritage (documentary film) to document, transpose, and transmit intangible cultural heritage (memories, poetry, song, stories). Through an analysis of the narrative form and cinematic style …

Listening To Taos Amrouche, A Kabyle Woman’S Singing Voice In A Context Of Exile And Immigration : Between A Search For Intimacy And Independence, Melek Chekili

Journal of Amazigh Studies

This article analyzes the vocal, musical and literary strategies Algerian Kabyle singer and writer Taos Amrouche employs to determine the place voicing holds for her in contexts of colonization, exile and migration. I demonstrate through her singing career and her 1975 autobiographical novel l’Amant Imaginaire, that within the ambivalences stemming from her birth in Tunisia to exiled Kabyle Christian converts and her emigration to France, Taos Amrouche’s singing voice provides a space where those ambivalences can co-exist. By being adamant about keeping her artistic activity close to her body and explicitly referring to sex in her writing, she exerts …

Special Economic Zones And Industrial Pollution: Evidence From Vietnam, Hannah Huang

Economics Undergraduate Senior Theses

Vietnam has seen rapid economic development, driven in part due to a proliferation of over 300 Special Economic Zones (SEZs) across the country since 1991. This paper exploits the staggered rollout of SEZs across the country to identify the effect of SEZ establishment on local air pollution in Vietnam from 2009 to 2019. I find that establishing an SEZ significantly reduces local PM2.5 concentration, with the largest reduction concentrated in the first years following establishment and attenuating over the longer term. I also find evidence that SEZs shift local firm composition toward higher-technology manufacturing, but zones focusing on dirtier industries …

Automatic Glossing In Under-Resourced Languages: Case Studies In Bribri And Cook Islands Māori, Carter D. Anderson

Linguistics Undergraduate Senior Theses

Interlinear glossing is a major task in Indigenous language documentation. In this paper, I explore how effectively two Large Language Models, ByT5 and Gemini 2.5 Flash, can produce interlinear glossed text. I also examine how prompting an LLM with different types of information (dictionary entries, other training samples, and translations) can augment model performance. I apply these models to two under-resourced Indigenous languages: Bribri, which is morphologically complex from Costa Rica, and Cook Islands Māori, which has a simpler morphology and is from the Cook Islands in the Pacific Ocean. ByT5 exhibits much better performance when glossing Cook Islands Māori …

Examining The Impact Of The Palisades And Eaton Fires On Air Quality In Los Angeles, Ryan Edward Glenn

Earth Sciences Undergraduate Senior Theses

Wildland-urban-interface (WUI) fires in the US are increasing in frequency and intensity with disproportionately large impacts on air quality and human health. In January 2025, the Palisades and Eaton wildfires swept across the Los Angeles Basin, burning residential areas and destroying vegetation. Despite their significance, WUI fires remain understudied compared to wildland fires, especially in regard to emissions composition. Here, I utilize a combination of field samples, modeling, and remotely-sensed datasets to survey the emissions profiles and variations during the 2025 Palisades and Eaton wildfires. I find that 75.1% of Los Angeles County was exposed to surface PM2.5 rated ‘unhealthy’ …

Assessing The Origin Of The Talus Deposit In King Ravine In The Presidential Range Of New Hampshire, Margaret M. Keating

Earth Sciences Undergraduate Senior Theses

The timing and mechanisms driving the retreat of the Laurentide Ice Sheet (LIS) after the Last Glacial Maximum (LGM; 26-19 ka) in the Presidential Range of the White Mountains, New Hampshire, remains inconsistently interpreted. King Ravine, located within the Presidential Range, contains a landform that preserves geomorphic evidence relevant to this debate. Here, I investigate the origin of this landform by assessing its age, surficial morphology, and internal structure. I present a topographic analysis of King Ravine, including a detailed new geomorphic map of the drainage basin and deposit. To constrain the timing of landform formation and activity, I determined …

Felony Murder: What Courts Ignore In Ohio Rev. Code § 2903.02(B), Richard S. Walinski

Et Cetera

Ohio has two levels of felony murder. One is aggravated felony murder, 2903.01(b). It is an approximate equivalent of the common-law felony-murder rule. The other is a felony-murder rule for the lesser offence of simple murder, 2903.02(B). In felony-murder cases prosecuted under Ohio Revised Code § 2903.02(B), the nearly universal practice among the lower courts in Ohio is to ignore certain explicit text in the statute.

To warrant a conviction, 2903.02(B) requires that death have occurred as a proximate result of the defendant’s having committed or having attempted to commit one of many predicate offenses that the General Assembly labeled …

Mental Health Transition Of Care Across State Lines: The Perspectives Of College Students, Caroline E. Hanson

Washington Semester Program

The mental health of first- year college students has a strong effect on their ability to transition smoothly and successfully to college (Young, C. C., & Calloway, S. J. (2015). For all students, the transition to college is stressful, filled with adjusting to new surroundings, schedules, and people. In addition to the social and environmental changes, college students are going through immense cognitive developments, specifically in their self-concept, self-esteem, and identity (Berk, 2023).

Composing Playgrounds, Rebecca Suju Abraham

Dartmouth College Master’s Theses

This thesis explores music composition as the design of “playgrounds”: structured systems that invite participation, interaction, and the emergence of shared musical experience. Drawing on a background in engineering and a practice rooted in improvisation and community, I investigate how compositional authority can be exercised through the creation of constraints instead of fixed outcomes. These systems are structured enough to support coordination and open enough to allow for play and collective agency. The work is situated within practice-based research and engages qualitative methods to reflect on a series of projects developed over the course of my MFA in Sonic Practice. …
