Hard Disk Drive Reaction Wheel System For Cubesat Architecture, Nidhi Sonwalkar, Venkata Chalamalasetty, Dionna Parina, Parishee Bajaj

Small Satellite Conference

Small satellites have become prevalent within the aerospace industry due to their ability to provide an inexpensive and easily accessible platform for technology demonstrations. Reaction wheels are typically selected for these missions’ attitude and rate control due to their small form factor. Their downside, however, is high cost, upwards of thousands of dollars, which does not align well with the low budget of many small satellites. To address this issue, alternative momentum-actuator technologies can be implemented that, similar to traditional reaction wheels, impart torques for actuation but require much less mass, volume, power, and money. This manuscript discusses the implementation …

Peek-Guided Neural Network Pruning For Deployment On Low Swap Hardware, Mackenzie J. Meni, Blake Gisclair, Ryan T. White, Trupti Mahendrakar

Small Satellite Conference

Deploying deep learning models onboard spacecraft is limited by strict size, weight, power (SWaP), and bandwidth constraints. Standard object detection networks like YOLO or Faster R-CNN are too computationally heavy for real-time use in space. We present a pruning framework using PEEK (Probabilistic Explanations for Entropic Knowledge extraction), an entropy-based interpretability method that pinpoints low-information layers for removal. Applied to YOLOv5 for Rendezvous, Proximity Operations, and Docking (RPOD), this approach cuts model size by up to 30% and compute cost by 25%, with only minor accuracy trade-offs—enabling faster, reliable detection on low-SWaP spacecraft platforms.

Chemistry Faculty Publications

Singlet fission (SF) and triplet–triplet annihilation (TTA) are processes which may be exploited to boost the efficiency of solar energy technology. Despite being studied since the late 1960s, the mechanism of singlet fission is still not fully understood. This is partly because the main technique used to study singlet fission, optical or visible/near-IR transient absorption spectroscopy, cannot distinguish between the strongly coupled triplet-pair state1(TT), weakly interacting triplet pairs (T..T), and independent triplet states T1+ T1. To solve this problem, we combine transient optical spectroscopy performed as a function of magnetic field and transient electron …

The Governor’S Cabinet Project A Study Of The Evolution Of The Executive Branch, Revis. L. Edmonds Aug 2025

The Governor’S Cabinet Project A Study Of The Evolution Of The Executive Branch, Revis. L. Edmonds

Theses and Dissertations

In Arkansas’s long path toward modernizing its executive branch, it may appear to the casual observer that the state was locked in a process in which its politics and its culture were engaged in a longstanding tug-of-war between traditionalists and modernizers—a conflict complicated by the state’s personality-based politics and restrictive post-Reconstruction constitution. It has often been asserted that the conflict, in Arkansas’s case the romanticizing of rural life as opposed to the economic and social interests of the fast-growing suburbs of Central and Northwest Arkansas, explains a great deal of this slow transition. This attitude was largely a product of …
