Vibration Control In Uavs For Enhanced Lidar Accuracy Using Metamaterials, Kylie Michaud

Student Research Symposium (SRS)

As technology develops, new systems are being created to deliver increased accuracy, cost-effectiveness, and overall efficiency. A specific example of this is LiDAR sensors onboard UAVs for 3D mapping applications of structures. As these sensors become lighter, this allows manufacturing to use smaller UAVs for closer and more confined environmental spaces. However, smaller UAVs introduce higher vibrational frequencies, those that current systems struggle to mitigate. The implementation of metamaterial structures can act as a dampener for these high frequency ranges. Metamaterials can be used to create bandgaps, which can enable frequency ranges that can prevent vibrations from affecting UAVs. Implementation …

The Dangers Of Social Media In Political Theory, Eden M. Shimanek

Global Tides

Increasing political polarization is a prominent feature of the twenty-first-century political landscape, with social media playing a significant role. This essay evaluates social media as a political platform through Hannah Arendt’s notion of the Vita Activa, which describes the political realm and the ideas of totalitarianism. Using this framework, I argue that the surging political use of social media creates digital “echo chambers” that result from the loss of human plurality, which ultimately marks the diverse nature of the political realm. I would continue to argue that these chambers evolve into the notion that Arendt notes as world alienation or …

A Case Against Pragmatic Encroachment, Mahali Kuzyk

Global Tides

In their paper, Evidence, Pragmatics, and Justification Fantl and McGrath offer a seemingly intuitive and attractive route to a revision of what counts as epistemic justification and knowledge. They argue that knowledge is not just a matter of evidence, but depends in part on one’s practical situation. Higher stakes and different utilities can change whether a belief is knowledge-constituting. This essay will argue that Fantl and McGrath’s attempt to use their Knowledge-Action principle (KA) to back pragmatic encroachment ultimately fails.

Using ATM as an example case, we can showcase how the kernel language enhances …

Conceptual Exploration Of Film Cooling Techniques In Hydrogen Gas Turbines, Wen Wu

Student Research Symposium (SRS)

Film cooling is a key heat transfer technique that protects gas turbine blades from extreme temperatures, allowing higher turbine inlet temperatures and greater thermal efficiency. It works by ejecting a thin layer of cooler air from the compressor through small holes onto the hot surface, creating a protective film layer that lowers surface temperature and reduces thermal stress on blades. This process is vital in power generation and propulsion systems that operate near material limits. With growing emphasis on sustainability, film cooling has gained new importance in hydrogen-fueled gas turbines. Hydrogen combustion creates water vaper and low-density exhaust gases, which …

Artificial Genuine Intelligence: Why Constraint Matters More Than Values In Recursive Ai Systems, Thom Pham

Defensive Publications Series

Large language models are often described as hallucinating when they produce incorrect

or unsupported outputs. That label is useful descriptively, but it conflates several distinct

mechanisms, including local generation error, unsupported fabrication, and

interaction-driven reinforcement of an initially weak claim. This paper isolates the third

case.

We argue that a subset of hallucination-like behavior is better understood as Recursive

Narrative Amplification (RNA): a feedback dynamic in which an already introduced

claim gains authority through recursive reuse before sufficient external constraint has

refreshed or corrected the trajectory.

The paper also introduces aggregation-induced error as a distinct structural failure mode

arising from …

Gci #271 – Active Orbitronic Heat‑Pump Substrate (V2), Michael Victor Caldwell Mr.

Defensive Publications Series

GCI #271 proposes a solid‑state, vibration‑driven thermal‑diode‑like interposer for high‑density chip‑stacks. It moves beyond passive heat spreading by attempting to bias phonon transport in one direction using chiral‑phonon‑induced orbital‑like currents driven by an acoustic field and thermal bias.

At its core, GCI #271 combines:

• A high‑thermal‑polymer substrate (Dyneema‑UHMWPE / epoxy‑acrylate, based on Arachne‑23‑style concepts) that serves as the main “phonon highway” within the interposer.

• A Z‑cut α‑quartz thin film (5–20 µm thick) bonded on top, chosen because chiral‑phonon effects and orbital‑like responses have been observed in similar quartz‑like crystals when driven by thermal, optical, or acoustic excitation.

• Piezo‑driven acoustic excitation …
