Analysis Of Policies And Incentives For The Successful Implementation Of Hydrogen-Fueled Medium-Duty And Heavy-Duty Vehicles In Humboldt County, California, Alka Verma

Cal Poly Humboldt theses and projects

The 21st century has seen a significant rise in global greenhouse gas (GHG) emissions, with the transportation sector contributing 23% of these emissions. Medium-duty and heavy-duty vehicles (MD/HD) are particularly impactful, accounting for over a quarter of transport-related emissions. In Humboldt County, California, transportation represents 53% of total emissions, with MD/HD vehicles being a major contributor. As light-duty vehicles shift to zero-emission alternatives, the MD/HD sector faces unique challenges. Hydrogen fuel cell vehicles offer a promising solution, providing longer range, higher energy density, and quicker refueling compared to battery electric vehicles (BEVs). These features make hydrogen an attractive option for …

“Twist But Don’T Break:” Constellating Past And Present Barriers In Black Queer Multimodal Publishing That Shift Text Into Subtext; Addressing Acceptance Into Queer Creative Communities And The Void Of Black Voices Within, Kae Ann Dennert-Frederick

Cal Poly Humboldt theses and projects

What does it look like to reframe our understanding of intersectional work? Looking at multimodality I will walk through the multiple frameworks by asking how Black Queer publishing of Young Adult fiction uses visuals to describe what cannot be said and what choices are made to show community structure and language, while also having to adapt for publication standards. I have researched this by looking into examples of Queer publishing (any representation of queerness in a form of publishing—in the text and sometimes in the authors' identity), as well as authors’ use of visuals to say what cannot be said …

Entry Surface And Hole Path Deviations In Inclined Bone Drilling, Trevor Liepa

IdeaFest 2026

This study focuses on improving surgical precision by examining top surface deviation and hole path during drilling across various inclination angles and spindle speeds. By analyzing these geometric outcomes, the study aims to better understand tool deviation and its relationship to drilling forces. A clearer understanding of how these factors influence hole trajectory and entry conditions directly impacts screw hole quality. Ultimately, improving control over top surface deviation and hole path can lead to more accurate drilling and better surgical outcomes.

Tms Phantoms For Investigating Multimodal Neuromodulation Procedures, Wesley H. Lohr

Theses and Dissertations

Evidence suggests that combining deep brain stimulation (DBS) and transcranial magnetic stimulation (TMS) is potentially unsafe for certain TMS target locations, though TMS can alleviate several DBS-resistant PD symptoms such as speech impairment, freezing of gait, and dysphagia. Addressing this issue, head phantoms designed for TMS with embedded electric field (E-field) triaxial dipole probes (TDPs) are used to investigate a tunable magnetic shield that can protect implants from periphery E-fields and focalize magnetic fields. Through segmentation of MRI files, 3D printing, and injection molding of CNT-PDMS conductive composites, anatomical head phantoms are created. Anchoring TDPs to clinically relevant regions in …

Religious Television Of Ukraine In Shaping Spiritual Identity In The Context Of Contemporary Media Practices, Oleh Sokolovskyi, Vadym Slyusar, Maksym Melnychuk, Yuliia Kondratiuk

Occasional Papers on Religion in Eastern Europe

The article is devoted to analysing religious television in Ukraine as a key institution of contemporary sacred communication, which shapes a new configuration of spiritual presence within the digital media space. Religious TV channels are examined as mediatized spaces for producing and transmitting symbolic meanings, within which traditional theological narratives are adapted to the demands of audiovisual culture, and the sacred acquires new forms of visualisation, emotional accessibility, and communicative dynamism. It is demonstrated that television broadcasting provides a unique format of spiritual support, enabling faith communities to participate in prayer practices, catechetical programmes, and moral-ethical discourse beyond the boundaries …

Digitalisation In The Voluntary Sector: An Empirical Study On The Determinants Of It Acceptance, Deniz Dogu

School of Engineering, Computing and Mathematics Theses

Digitalisation represents a major societal trend that drives economic and social trans-formation by increasingly embedding digital information and communication techno-logies (ICT) into processes, interactions, and everyday activities across all domains of life. However, the voluntary sector has yet to fully embrace ICT. The extent to which volunteers integrate digital tools depends on factors such as technical infrastructure and willingness to adopt IT. Research in this area remains limited, and findings are often difficult to transfer across different national contexts. This PhD research addresses the gap in understanding IT acceptance in volunteering, using Germany as a case study. A comprehensive literature …

Towards An Evaluation Of The Business Value Of Ai: A System Dynamics Approach, Ganesh Sankaran

School of Engineering, Computing and Mathematics Theses

In the early 2010s, when Artificial Intelligence (AI) emerged from the latest "winter" of disillusionment, discussions about its use in decision-making tended to be dichotomous: humans or AI. More recently, consensus has shifted toward a complementary humans-and-AI perspective, recognising that augmentation, not substitution, is the more appropriate frame for AI's role in the foreseeable future. This shift foregrounds the challenge of evaluating outcomes in collaborative decision-making contexts.The thesis proposes a simulation-based framework, drawing on system dynamics, to evaluate whether complex, time-varying interactions between humans and AI agents result in collectively rational behaviour. The framework extends the observation of dynamic complexity …

Reframing Narratives, Reclaiming Futures: Antiracist School Counseling And Black And Brown Girls In Stem, Renae D. Mayes, Lia D. Falco, Shontell Zenon, Dequindre Hughes, Yijia Chen, Lydia Ross, Medha Dalal

Journal of College Access

Black and Brown girls often have educational experiences that stifle their career aspirations, especially in STEM fields. These experiences can be exacerbated by educators who misunderstand and refuse to recognize their STEM potential, thus limiting their opportunity to build STEM identities. School counselors can disrupt these experiences through antiracist practices that cultivate homeplace and joy for Black and Brown girls to heal and grow while working to address harmful policies and practices. In this paper, authors discuss how school counselors can specifically use antiracist school counseling practices to support Black and Brown girls in STEM as a part of multi-tiered …

Body Of Law: When Content Moderation Becomes Gender Oppression And Triggers Legal Consequences, Sarah E. Bahrenburg

Journal of Race, Gender, and Ethnicity

For as long as the Internet has existed, it has been used as a tool for good and as a tool for malice. However, there is a discrepancy between punishment for those maliciously invading individuals’ personal space and those posting consensual images of themselves for art or entertainment purposes (not to mention for work). Over the years, while attempting to create safe spaces for people to express themselves, the Internet has also created barriers to individuals doing just that. The Internet and the laws surrounding exposure therein have become increasingly misogynistic and anti-women’s sexual freedom. The laws encompassing safety on …

The Rise And Fall Of The First Atheist State: Albania’S Rediscovery Of Faith, Fatos Tarifa

Occasional Papers on Religion in Eastern Europe

This paper explores Albania’s unprecedented experience as the only modern state to constitutionally declare itself atheist. After World War II, Enver Hoxha’s communist regime sought to reshape society through radical ideological transformation. In 1967, the regime banned all religious practice, dismantled churches, mosques, and monasteries, and persecuted clergy. Religion was criminalized, while atheism was promoted as a central component of socialist identity, enforced through education, propaganda, and cultural policy. In 1976, Albania was proclaimed by its constitution the world’s first atheist state. The paper examines the historical circumstances that produced this extreme stance and its consequences: suppression of traditions, erosion …

A convergent mixed-methods design integrated student perception and mindset survey data …

Pre-Eruptive Timescales Via Olivine Diffusion Chronometry For Lava And Tephra Of The Schreibers Meadow Cinder Cone Eruption, Mount Baker (Kulshan), Wa, Sabrina Ansari

All Master's Theses

Mount Baker is a very-high threat Cascade volcano and is located near densely populated areas in northern Washington, putting many at risk if an eruption were to occur. Schreibers Meadow cinder cone is located on the southern flank of Mount Baker and produced the Sulphur Creek (SC) tephra and lava 9.8 ka. Previous work on the SC eruption used petrology and geochemistry to reconstruct the pre-eruptive magmatic architecture beneath Mount Baker Volcanic Field, including olivine-hosted melt inclusions to determine crystallization pressures, as well as plagioclase- and clinopyroxene-derived diffusion timescales to determine magma storage timescales of several months and recharge-to-eruption timescales …

Gis Is A Tool, Not The Story: The Journey Towards An Ethnographically Informed Gis Analysis Of Frenchman Coulee, Eastern Washington, Joseph T. Gambino

All Master's Theses

Geographic Information Systems (GIS) have seen increased use in ethnographic and archaeological studies over the last several decades. Though revolutionary in their ability to predict and document sites of archaeological or cultural significance, they remain limited in their capacity to communicate the full extent of potential values certain geographies offer to both cultural specialists and their communities. These limitations are amplified when attempting to represent how the landscape is experienced within GIS’s statistical framework. In this manuscript I present different approaches to GIS modeling that attempt to identify some of the advantages Frenchman Coulee could have offered to the Indigenous …
