Cmac Smallsat Atmospheric Correction With Scene Statistics: Superior Accuracy In Near Real-Time, David Groeneveld, Tim Ruggles

Small Satellite Conference

The future of remote sensing is imaging smallsats; however, assuring their data utility requires atmospheric correction (AC). Current methods are difficult to apply and often fail to provide accurate surface reflectance retrieval even for the most common levels of atmospheric aerosol loading; this impediment is increasing annually due to wildfires induced by climate change. Closed-form Method for Atmospheric Correction (CMAC), developed for smallsats using Sentinel-2 data, is applicable to all imaging satellites. CMAC uses only scene statistics for automated near real-time AC while bypassing ancillary data that delays existing methods by days. In this paper, data from two research-grade satellite …

A Novel Approach To Small Form-Factor Spacecraft Structures For Usage In Precision Optical Payloads, Tyler Ritz, Henry Chong, Patrick Kelly

Small Satellite Conference

Precision optical payloads will soon experience a boom in manufacturing scale with the onset of proliferated satellite constellation concepts. Presently, the cost of assembly for a single unit can reach upwards of $500,000. Reduction in recurring engineering and assembly complexity can reduce this figure by up to two orders of magnitude. This paper discusses one potential solution which relies on consistent structural components that are easily manufactured in bulk quantities to facilitate general uses while also enabling high-precision mounting in designated payload slots. This proposed approach combines standardized struts and panels able to be connected and stacked in a variety …

Is Rxr Alpha A Mitochondrial Transcription Factor?, James Weiser, Megan Bestwick Phd

Linfield University Student Symposium: A Celebration of Scholarship and Creative Achievement

Mitochondria are important organelles in most eukaryotic cells due to their essential role in metabolism. Within the matrix of the organelle, they also have their own genome (mtDNA) which encodes many of the protein subunits for complexes within the oxidative phosphorylation (OXPHOS) pathway. The remaining OXPHOS protein complex subunits are encoded in the nuclear genome, translated in the cytosol and imported into mitochondria. Transcriptional coordination between these two genomes to produce functional OXPHOS complexes is critical to maintaining cellular homeostasis. This process likely requires regulatory proteins/transcription factors that determine the expression of these genes. Retinoid X receptor alpha (RXRα) is …

Slap! (2023) For String Quartet, Elana Gatien

Linfield University Student Symposium: A Celebration of Scholarship and Creative Achievement

Slap! for String Quartet (2023) was written for the Pyxis Quartet as part of the Lacroute Composer Readings and Chamber Music Mentorship Program at Linfield University. It was inspired by Kenji Bunch’s Supermaximum, which uses foot and hand percussion in a work for a string ensemble. Supermaximum was one of my first encounters with unconventional techniques in western art music, and the wonder of it stuck with me. I use some of those techniques in this string quartet, reshaping that wonder and making it my own.

In-Orbit Demonstration Of Precise Point Positioning For Real-Time On-Board High-Accuracy Orbit Estimation Of Leo Satellites, Javier Tegedor, James Bartle, Jonathan Ward, Xianglin Liu, Scott Glazier, Pieter Van Duijn

Small Satellite Conference

Satellites in Low Earth Orbit (LEO) are typically equipped with GNSS (Global Navigation Satellite Systems) receivers to obtain real-time positioning, velocity, and timing. Until now, onboard GNSS positioning accuracy in LEO has been limited. Where more accurate state vector estimates are required the raw GNSS data must be post-processed on the ground.

Precise Point Positioning (PPP) is a GNSS positioning technique which allows users to obtain absolute high accuracy positioning. While PPP has been extensively used for precise Earth-based navigation, it has not been used for enhancing the positioning accuracy of satellites in LEO until now.

This paper describes how …

Ending Law Enforcement's Accountability Crisis: The Case Against Qualified Immunity, Mikayla Minton

Linfield University Student Symposium: A Celebration of Scholarship and Creative Achievement

People have been marching in the streets to speak up against police brutality, and many people care about reducing police misconduct, but not everyone knows about qualified immunity. In some cases, courts can excuse officers’ unconstitutional actions to prevent officers from being held accountable in civil proceedings. Almost all police misconduct is excused and incentivized by one legal doctrine: qualified immunity. 42 U.S. Code § 1983 states that the doctrine “protects a government official from lawsuits alleging that the official violated a plaintiff's rights, only allowing suits where officials violated a ‘clearly established’ statutory orconstitutional right.” In this essay, I …

Electrical Scarecrow, Boyu Liu, Tianbao Xie

Linfield University Student Symposium: A Celebration of Scholarship and Creative Achievement

Abstract

This poster illustrates the use of audio sensors to detect the response of birds and speakers to startle them. Modern agriculture suffers from frequent losses due to the destruction of crops by birds; thus, inexpensive tools need to be developed to protect crops. The general idea is to detect high-frequency birdcalls which triggers an audio circuit designed to make noise. A consideration of the feasibility for use in the field will be discussed, as well as potential improvements and limitations.

Brainstack – A Platform For Artificial Intelligence & Machine Learning Collaborative Experiments On A Nano-Satellite, Marcus Murbach, Eric Barsczc, L. Seth Schisler, Alejandro Salas, Kwabena Boateng, Gregoire Marty, Avery Brock, Malachi Mooney-Rivkin, Stanley M. Krześniak

Small Satellite Conference

Space missions have become more ambitious with exploration targets growing ever distant while simultaneously requiring larger guidance and communication budgets. These conflicting desires of distance and control drive the need for in-situ intelligent decision making to reduce communication and control limitations. While ground based research on Artificial Intelligence and Machine Learning (AI/ML) software modules has grown exponentially, the capacity to experimentally validate such software modules in space in a rapid and inexpensive format has not. To this end, the Nano Orbital Workshop (NOW) group at NASA Ames Research Center is performing flight evaluation tests of ‘commercially’ available bleeding-edge computational platforms …

Using Community Organizing Best Practices To Redesign The Dart Organizers' Institute, Anna Long

Capstone Collection

This Training-of-Trainers Course-Linked Capstone project explores three approaches to community organizing from three different scholar-practitioners. It begins with the father of grassroots organizing, Saul Alinsky’s, neighborhood-based and congregation-based approach. Alinsky’s approach is followed by Alicia Garza’s approach; Garza is the founder of the international Black Lives Matter movement. It ends with author and organizer adrienne maree brown’s Emergent Strategy approach. This paper will synthesize all three approaches, ultimately identifying four recommended approaches to community organizing: power, motivation, emotion, and centering impacted voices. The four recommended approaches will be used to evaluate the new organizer training (Organizers’ Institute) for the Direct …

Decolonizing Wash Practices Between National Policies & International Standards: A Case Study In Tanzania, Mary Thibodeau

Capstone Collection

The international community has developed guidelines and standards for the maintenance of water and sanitation (WASH) in states from the end of the 20th century to present and have often been criticized for their lack of contextual adaptations in the standards that states are expected to implement universally. The research explored how international standards on WASH have applied decolonized methods of interventions to guide the development of culturally relevant national policies. Tanzania was chosen as a case study to conduct a comprehensive review of the states’ integration of international standards within their policies through a decolonial perspective. The study included …

Annotation Of The Microtubule Star (Mts) Gene In Drosophila Ananassae Using Drosophila Melanogaster As A Reference Organism For Comparative Genomics, Danesh Khazaei, Catherine Reinke

Linfield University Student Symposium: A Celebration of Scholarship and Creative Achievement

Our lab is using comparative genomics protocols to explore the evolution of the insulin-like signaling pathway in Drosophila species spanning 40M years of evolution. This project aims to annotate an ortholog of the Drosophila melanogaster gene microtubule star (mts) in the incompletely characterized Drosophila ananassae genome. Genome annotation is the process of creating gene models, or labelling areas of interest in a species’ genome for further investigation, using genome comparisons and large data sets characterizing gene expression, which is the production of RNA from select regions of genomic DNA. We are using comparative genomics and bioinformatics protocols to …

The Effect Of Low Concentrations Of Copper On Mitochondria And Activity In Yeast Cells, Emma Sammartino, Megan Bestwick

Linfield University Student Symposium: A Celebration of Scholarship and Creative Achievement

Mitochondria are essential organelles in both yeast and human cells due to their role in metabolism, ATP production via the oxidative phosphorylation (OXPHOS) pathway, and other regulatory cellular processes. Using yeast as a model organism to study mitochondrial function in a chronological lifespan assay allows experiments to be conducted over a shorter timeframe and allows for connections to be made to human cells. Our aim is to investigate how exogenous copper in the mitochondria of yeast affects the production of reactive oxygen species (ROS), protein expression, and enzyme activity during yeast lifespan. Small amounts excess copper added to growth media …

A Decision Framework For Allocation Of Constellation-Scale Mission Compute Functionality To Ground And Edge Computing, Jaime Ramirez, Caleb Royer, Brian Free, Owen Brown, Robert Polutchko

Small Satellite Conference

This paper explores constellation-scale architectural trades, highlights dominant factors, and presents a decision framework for migrating or sharing mission compute functionality between ground and space segments. Over recent decades, sophisticated logic has been developed for scheduling and tasking of space assets, as well as processing and exploitation of satellite data, and this software has been traditionally hosted in ground computing. Current efforts exist to migrate this software to ground cloud-based services. The option and motivation to host some of this logic “at the edge” within the space segment has arisen as space assets are proliferated, are interlinked via transport networks, …

Shielding Considerations For Cubesat Structures During Solar Maximum, D. Laurence Thomsen, Thomas M. Jordan, Larisa Milic, William Girard

Small Satellite Conference

The purpose of this lessons learned paper is to communicate the utility of shielding in small spacecraft planning for the support of mission assurance and reliability. Numerous SmallSats have been flying in polar low Earth orbit for science, communications, technology demonstrations, and imaging with academic, commercial, and government interests. Shielding has been part of mission assurance and reliability from the advent of long duration spacecraft missions. The Shields-1 CubeSat has been operating in polar low Earth orbit since 16 December 2018 with atomic number (Z)-grade radiation shielding and demonstrates shielding effectiveness. Shields-1 has collected a representative example of solar minimum …
