Understanding The Spatial Characteristics Of Urban Morphology And Its Application, Md Sohel Rana May 2025

Understanding The Spatial Characteristics Of Urban Morphology And Its Application, Md Sohel Rana

Theses - ALL

Rapid urbanization due to the population boom in urban areas changes the physical layout and structures of cities including buildings, streets, open spaces, and amenities, which are collectively defined as urban morphology. Microclimate dynamics of urban environments, such as airflow, heat retention, and pollution dispersion, are profoundly affected by urban morphology. Although the roles of urban morphology at small spatial scales (e.g., single buildings, building complexes, or buildings within a block) in microclimate dynamics have been extensively studied, the scale-up effect of buildings at the city scale on microclimate dynamics is still not fully understood. In this thesis, I examined …

Curricular Reconciliation: Equitable, Inclusive, And Accessible Approaches To Professional Writing Through Coalition-Led Technical Communication, Lerie M. Gabriel May 2025

Curricular Reconciliation: Equitable, Inclusive, And Accessible Approaches To Professional Writing Through Coalition-Led Technical Communication, Lerie M. Gabriel

Dissertations - ALL

This dissertation examines the process of revising a core professional writing course to integrate anti-ableist and anti-racist pedagogies throughout its design. Focusing on the pragmatic and theoretical aspects of this collaborative curriculum redesign, this dissertation examines how an intersectional, Black feminist approach to professional and technical communication curricula disrupts neoliberal legacies. In addition to limiting students’ critical thinking skills, interdependence, and imagination of workplace ethos, these legacies affect instructors' experience of teaching professional and technical writing (PTW), particularly those individuals who hold (multiply) marginalized identities. Through archival research and interviews, this dissertation contextualizes these revisions by exploring the rhetorical history …

The Formation And Control Of Wrinkling Topographies On 4d Printed Substrates, Johnson Nana Agyapong May 2025

The Formation And Control Of Wrinkling Topographies On 4d Printed Substrates, Johnson Nana Agyapong

Dissertations - ALL

Mechanical instability-driven wrinkling atop shape memory polymer (SMP) substrates is a cost-effective surface patterning alternative to soft lithography that offers spatiotemporal control of surface topography for applications in thin film metrology, biomimicry, microfluidics, and cell studies. The wrinkle morphologies demonstrated to date have been predominantly simple aligned wrinkles on the surface of 2D geometries, so there remains a need for a straightforward SMP strain programming strategy that can achieve simple and complex wrinkle morphologies on 2D and 3D geometries. To address this need, we integrated a single-step SMP fabrication approach, programming via printing (PvP), with mechanical-instability-driven wrinkling to fabricate 2D …

Stranded In Transit: Migrants' Borderland Experiences En Route To Europe, Ibrahim Emre Yanik May 2025

Stranded In Transit: Migrants' Borderland Experiences En Route To Europe, Ibrahim Emre Yanik

Dissertations - ALL

This dissertation explores the lived experiences of migrants stranded in prolonged transit amid the intensifying securitization of the European border regime. While contemporary policy frameworks aim to deter unauthorized migration through externalized controls, digital surveillance, and restricted legal pathways, these measures have instead produced new forms of precarity, immobilization, and liminal existence. Focusing on Istanbul as a key site of transit and containment, the research examines how migrants navigate conditions of legal uncertainty, economic marginalization, and social isolation while resisting the structural constraints imposed upon them. Drawing on ethnographic fieldwork conducted in Istanbul—including semi-structured interviews and participant observation—this study adopts …

Biodegradable And Bioactive Polyurethane Foams To Improve Traumatic Wound Healing, Natalie Petryk May 2025

Biodegradable And Bioactive Polyurethane Foams To Improve Traumatic Wound Healing, Natalie Petryk

Dissertations - ALL

Every year, 1.5 million people die from uncontrolled bleeding in traumatic wounds, such as gunshot wounds. Gauze dressings have remained the gold standard of treatment for traumatic wounds, but gauze must be removed, resulting in wound rebleeding. Furthermore, gauze removal within an approved time frame is not always possible in remote settings, like on a battlefield, presenting a critical need for a safe and effective dressing that can control bleeding over prolonged periods. To overcome these limitations, this work focuses on a novel biomaterial to be used as a permanent dressing to stop bleeding and facilitate healing. In previous work, …

Deformations Of Thin Membranes In Incompatible Geometries And Interactions In Mechanical Hysteron Systems, Zachariah Schrecengost May 2025

Deformations Of Thin Membranes In Incompatible Geometries And Interactions In Mechanical Hysteron Systems, Zachariah Schrecengost

Dissertations - ALL

Soft reconfigurable systems exhibit behaviors which are highly dependent on their geometries. Thin membranes can deform in a myriad of ways as they navigate geometries different from their own in an energy efficient manner. Behaviors in mechanical hysteron systems are influenced by the geometry of the interactions and global driving. This dissertation focuses on two different types of systems which are governed in part by their geometries: thin membranes in geometrically incompatible configurations and interacting mechanical hysterons. A thin membrane forced into a conflicting geometry with an incompatible metric will deform in highly non-trivial ways. These deformations are an attempt …

Geography In Service To The Community, Albert Redsun May 2025

Geography In Service To The Community, Albert Redsun

The Geographical Bulletin

For many years geographers spent much of their professional efforts describing the landscape and man's activities. These were noteworthy, necessary, and valuable contributions. As we grew (just as all disciplines do) we searched for those meaningful relationships of man and land. We still search. Many relationships are obvious. Many that will be discovered in the future will someday be obvious. It is clear that we will need the continuing quest by researchers in our field. Researchers now seek to predict. The introduction of quantification techniques has allowed for more refined analysis and prediction. As researchers open more and more doors …

Hops In The United States, Edgar M. Hadley May 2025

Hops In The United States, Edgar M. Hadley

The Geographical Bulletin

For more than a thousand years the virtue of the hop has been recorded, and it is possible that hops have been cultivated since prehistoric times. More than five hundred years have passed since the domesticated hops were brewed in middle Europe, but wild hops were used much earlier, and are brewed in Syria even today. Hops were introduced to England in the wild, but much later came into prominence after being introduced into Kent by Flemish immigrants about 15241.

Survey Of Symmetric Encryption Techniques Implemented Over Gpu Platforms, Hawraa Moussa, Ahmed Fanfakh

Journal of Intelligent Informatics, Networking, and Cybersecurity

Encryption is one of the most important techniques used to deliver protection solutions. Symmetric encryption uses a single key for encryption and the decryption process. Symmetric encryption implements block encryption, replacement, and switching. Consequently, it is problematic if the private keys obtained from the protocols are frequent in certain states or exhibit reduced unpredictability. Several researchers applied the cryptography method in a parallel fashion to minimize the time needed to complete encrypting and decrypting data procedures. Numerous viable solutions have been found to increase the levels of encryption algorithm performance made by the researchers to use parallelism to boost their …

Integration Of Zero Trust Architecture And Machine Learning For Improving The Security Of Software Defined Networking: A Review, Manar H. Bashaa, Wesam S. Bhaya, Nabeel H. Kaghed Al-Aaraji

Journal of Intelligent Informatics, Networking, and Cybersecurity

Many add new networks, but management has a lot of work to do as well. Software Defined Networking (SDN) was conceived to address these challenges in a more structured way, SDN allows centralized management of the network and provision of software based traffic understanding making it relatively easier to manage large scale networks. The downside to SDN is its vulnerability to cyber attacks. The more centralized the structure the more efficient it is, however the more specific weaknesses it possesses such as DoS attacks for example. The ``perimeter'' approach to security is outdated with today's security technology. Zero Trust Architecture …

The Diverse Roles Of Complex Glycans In Synapse Development And Function, Peng Zhang May 2025

The Diverse Roles Of Complex Glycans In Synapse Development And Function, Peng Zhang

Faculty Scholarship

Protein glycosylation is a critical post-translational modification that mediates a myriad of biological functions, including neuronal development in the brain. Stages of neuronal development include neurogenesis, neuronal migration, axonal guidance, synapse formation, and activity-dependent synaptic remodeling and plasticity. Among these, synapse formation and plasticity are essential to establish and maintain neuronal circuits for proper brain function. Yet, the physiological role of glycans at synapses remains poorly understood. This is especially true for complex glycans, known for decades to be present on the cell surface or extracellular matrix, including the microenvironment around synapses. In this review, we highlight recent examples of …
