Staff Education To Improve Staff Knowledge Regarding Candida Auris, Nkechinyere Ejelonu

Walden Dissertations and Doctoral Studies

This Doctor of Nursing Practice project was a staff education project regarding Candida auris, a multidrug-resistant fungus recognized by the Centers for Disease Control and Prevention (CDC) as an urgent global health threat due to its high mortality, environmental persistence, and resistance to common disinfectants. Staff play a crucial role in infection prevention; however, limited awareness and inconsistent knowledge of Candida auris contribute to potential transmission in skilled nursing home settings. The project question was as follows: Among staff members in a skilled nursing facility, does an evidence-based educational intervention improve knowledge of Candida auris infection prevention as compared pre- …

Beyond Extremism: Rethinking Anarchism In Contemporary Indonesian Security Discourse Through Anarchist Criminology, I Gusti Ngurah Aditia Tjandra Asmara

Jurnal Kriminologi Indonesia

This article examines how contemporary Indonesian security discourse increasingly frames anarchism through the categories of radicalism, extremism, and national security threats. Responding to the emergence of academic and security-oriented narratives that position anarchism as a form of anti-state extremism, this article asks how anarchism is represented and securitized within contemporary Indonesian criminological and security discourse. Using a qualitative critical-discourse analysis approach, this article draws upon perspectives from Anarchist Criminology and Cultural Criminology to examine the construction of anarchism within contemporary Indonesian security narratives. The findings demonstrate that anarchism is frequently reduced into a simplified and homogeneous category of extremism through …

Nasa’S Ecostress Satellite Reveals Widespread Midday Depression In Ecosystem Evapotranspiration, Jingyi Bu, Jingfeng Xiao, Joshua B. Fisher, Yiqi Luo

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Plants often exhibit a midday depression in water use (i.e., transpiration), reflecting a constraint on their ability to sustain maximum water transport, which may occur at the cost of reduced photosynthesis. Eddy covariance observations and geostationary satellites cannot quantify this widespread phenomenon globally while resolving fine-scale spatial variability. Using evapotranspiration measurements from the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) and machine learning, we quantify the global distribution of midday depression in evapotranspiration. Midday depression primarily occurs during peak-growing seasons in temperate zones and dry periods in the tropics, with a morning shift of the peak evapotranspiration time …

Design And Implementation Of A Semi Automated Uhf Ground Station For Small Satellite Missions: A Case Study From India, Binoop Joseph, Vinayak Manoj, Thomas Francis, Madhav Vinod, Nikhil Jacob, Salih Majeed, Prajin I. R., Meghana Suresh, Salman Al Fariz K., Sijo George, Anish Chandra B. S., Anamika Kamath, Anjay Sudesh, Anurag Reghu, Aravind M. B., Manu Mohan, Ashfaque K. P., Amal Chandran

Small Satellite Conference

Mission success ultimately depends on reliable telecommand and telemetry links between spacecraft and Earth. For small satellites operating under tight power, size and link margin constraints, a technically robust and regulation compliant ground station is a mission critical enabler rather than an afterthought.

This poster presents a case study of a semi automated UHF ground station designed, built and commissioned by HEX20 in Thiruvananthapuram — one of the earliest privately owned and operated satellite ground stations in India — covering the hardware signal chain, the tracking and decoding software stack, integration and calibration, and the regulatory path to operation.

Magnetic Balancing For Microvibration Reduction In Passive Magnetic Bearings For Smallsat Reaction Wheels, Deckers Niel, Baekeland Mante, Cuypers Cedric, Seiler Rene, Vandepitte Dirk, Delabie Tjorven

Small Satellite Conference

Reduction and mitigation of microvibrations constitutes a crucial field of interest in the research of spacecraft reaction wheels. This applies all the more so in small satellites, where even minimal sources of vibrations lead to imprecision of onboard instruments. To address this, magnetic bearings offer contactless support, and thus prevent several sources of microvibrations that exist in classical ball bearings, for instance the mechanical imperfections in rolling elements. The inherently low stiffness of magnetic bearings also significantly reduces the transmitted forces in reaction wheels. Another advantage of contactless support is its potential longer lifetime because of the absence …

Evaluating Performance Of Hardware-Accelerated Vessel Detection Algorithms, Michael Tietz, John Warner, Quinton Davidson, Douglas Carssow

Small Satellite Conference

Earth observing satellites contribute to the monitoring of maritime activity by enabling large-scale coverage of open water. For example, spacecraft data can be used to monitor and combat Illegal, Unreported, and Unregulated (IUU) fishing that occurs in coastal and international waters across the globe. However, information latencies limit the utility of space-based sensors for operational users who need real-time situational awareness. These limitations are especially pronounced for small spacecraft with limited power generation and downlink capabilities. In recent years, the devices and tools that enable edge computing and near real-time downlink from small spacecraft have improved substantially. Equipped with these …

Dynaband: Context-Aware Dynamic Band Selection For Onboard Hyperspectral Processing In Small Satellites, Rishigesh Jayananth, Brasen Sheeh

Small Satellite Conference

Hyperspectral small satellites now collect far more data than they can return to the ground. A single acquisition spans tens to hundreds of spectral bands, yet the downlink window on one pass carries only a fraction of it, so operators are forced to drop scenes, bin bands coarsely, or store data that never reaches the ground. Much of this waste is avoidable. When the task is known before the spacecraft images, whether to map water, monitor vegetation, or pick out a mineral signature, only a handful of bands actually carry the answer; the rest is paid for in downlink and …

Metadata-Conditioned Dark-Frame Modelling And Hsdr-Scanfusion Denoising: A Physics-Informed Independent Tool For Low-Cost Hyperspectral Small-Satellite Calibration, Nooh Adnan, Kyaw Thiha, Raffael Gil Dela Cruz, Li Cheng Zheng, Faijul Amin, Areeba Khan, Sameha Tasnim, Sung Jegal, Yunhan Bao, Iliya Shofman

Small Satellite Conference

Hyperspectral imaging in the shortwave-infrared spectrum is valuable for orbital Earth observation, but its use on low-cost, resource-constrained small satellites is limited by thermally dependent dark current, fixed-pattern noise, and intermittent access to matched calibration frames. Traditional mitigation through active cooling, shutters, or frequent dark-frame acquisition can be difficult to accommodate within small-satellite mass, power, volume, and operations budgets. This paper presents a physics-informed independent calibration tool that reconstructs condition-matched dark response from acquisition metadata rather than relying on hardware-heavy calibration at every operating point. The framework combines a stochastic dark-noise simulator, a metadata-conditioned neural dark operator that predicts spectral-spatial …

Event-Driven Spacecraft Operations Demonstrated On Mms, Miles Bengtson, Alexander Barrie, Joseph Patton, Liam Greenlee, Paul Wood, Marcus Piquette, Russell Bjella, Matthew Chang, Joshua Paul

Small Satellite Conference

Operations engineers face the challenging task of capturing high-value science data while maintaining spacecraft health and functionality and responding to a dynamic space environment using limited information. This task is becoming increasingly complex as missions involve increasingly large numbers of spacecraft, target more elusive science signatures, and operate under growing budget and staffing constraints. Conventional pre-programmed time-sequence commands become increasingly burdensome for multi-spacecraft missions and are fundamentally incapable of reacting to rare, transient science events in real time.

To address this challenge, we have developed MEDOS: the Module for Event-Driven Operations of Spacecraft. Unlike machine learning and neural-network approaches, MEDOS …

Let’S Give The Fsck Up On Secded, Heather M. Quinn, Andrew Pineda, Gary Swift

Small Satellite Conference

Many space systems use error correcting codes (ECC) for handling radiation-induced upsets in memories. The most used ECCs are Hamming and Hsaio, which are single-error correction/double-error detection (SECDED) codes. The widespread use of these codes can lead to a dangerous overestimation of system reliability. Instead these codes are one of the best documented methods for microprocessor-based system crashes, due to uncorrectable faults. Less well documented is how these codes can lead to silent data corruption caused by miscorrections, where multiple errors are detected as a single error and corrected erroneously.

ECCs have always been sensitive to time-dependent errors, where SEUs …

Design And Qualification Of A Compact, Deployable Dual-Monopole Antenna System For Remote Sensing Microsatellites, Alexander J. Murphy, Bryan Johnston-Lemke, Robert E. Zee

Small Satellite Conference

Spacecraft conducting signals intelligence (SIGINT) missions require highly capable radio-frequency (RF) payloads. While the larger 80 kg-class platforms offer increased payload capacities, strict internal volume limitations persist. These constraints sometimes require stowing instruments, such as the dual-monopole Very High Frequency (VHF) antenna presented in this work, directly beneath the solar wings. This requirement has imposed a strict height constraint on the VHF antenna, mandating a highly compact and reliable deployment mechanism that avoids snagging or jamming during deployment. 

This paper presents the mechanism design and qualification test plan of a novel, deployable dual-monopole VHF antenna system designed to increase satellite …

Proclaiming The Suppressed Truth: Romans 1:16-25, Michael D. Royster

Sermon Studies

When Paul wrote about “suppressing the truth,” he remembered the tactics used on those who proclaimed the Word of God. Before Paul’s conversion, he approved of Stephen’s public execution by stoning. After Paul’s conversion, he on more than one occasion fled the scene to escape persecution and attempted murder. Like Stephen, Paul became a proclaimer of the truth and faced an imminent threat of violence to further suppress his message. There exist possible homiletical directions the preacher may take and a range of collective illustrations that can bridge the ancient with the modern world concerning matters of the heart and …

Grounding Dependency Within Case Study Of Tourism In Cuba, Abby Mccarroll

Sociology Honors Projects

The research investigates the tourism industry in Cuba as a case study for dependency theory as articulated by Milton Santos’s Toward an Other Globalization. The research examines interactions between tourists and locals, and how Cubans navigate the contradictions of a socialist project embedded in a capitalist economy. Through an analytical macrosociological lens, the research contributes to wider considerations of dependency, economic sovereignty, and the uneven impacts of globalization. I argue that the case study of tourism in Cuba expands Santos’ theories to demonstrate how a country that refutes neoliberal ideology still finds itself trapped within the dynamic of dependency.

Small Satellite Conference

The ESA Scout HydroGNSS mission demonstrates a new generation of GNSS reflectometry (GNSS R) capabilities for hydrological climate monitoring from small satellites. HydroGNSS measures soil moisture, freeze–thaw state, inundation, wetlands and above ground biomass by exploiting both traditional incoherent Delay Doppler Maps (DDMs) and several innovative signal types not previously available from spaceborne GNSS R missions. Early in orbit results confirm successful acquisition of signals from Galileo, dual polarisation measurements, coherent complex channel data and reflections at the second GNSS frequency (L5/E5a). These enhanced measurements exhibit stronger than predicted performance and are expected to significantly improve retrievals of climate relevant …
