Communication-Efficient Federated Learning For Leo Constellations Integrated With Haps Using Hybrid Noma-Ofdm, Mohamed Elmahallawy, Tony T. Luo, Khaled Ramadan

Computer Science Faculty Research & Creative Works

Space AI has become increasingly important and sometimes even necessary for government, businesses, and society. An active research topic under this mission is integrating federated learning (FL) with satellite communications (SatCom) so that numerous low Earth orbit (LEO) satellites can collaboratively train a machine learning model. However, the special communication environment of SatCom leads to a very slow FL training process up to days and weeks. This paper proposes NomaFedHAP, a novel FL-SatCom approach tailored to LEO satellites, that (1) utilizes high-altitude platforms (HAPs) as distributed parameter servers (PSs) to enhance satellite visibility, and (2) introduces non-orthogonal multiple access (NOMA) …

Uncovering The Causes Of Emotions In Software Developer Communication Using Zero-Shot Llms, Mia Mohammad Imran, Preetha Chatterjee, Kostadin Damevski

Computer Science Faculty Research & Creative Works

Understanding and identifying the causes behind developers' emotions (e.g., Frustration caused by 'delays in merging pull requests') can be crucial towards finding solutions to problems and fostering collaboration in open-source communities. Effectively identifying such information in the high volume of communications across the different project channels, such as chats, emails, and issue comments, requires automated recognition of emotions and their causes. To enable this automation, large-scale software engineering-specific datasets that can be used to train accurate machine learning models are required. However, such datasets are expensive to create with the variety and informal nature of software projects' communication channels. In …

Unsafe Events Detection In Smart Water Meter Infrastructure Via Noise-Resilient Learning, Ayanfeoluwa Oluyomi, Sahar Abedzadeh, Shameek Bhattacharjee, Sajal K. Das

Computer Science Faculty Research & Creative Works

Residential smart water meters (SWMs) collect real-time water consumption data, enabling automated billing and peak period forecasting. The presence of unsafe events is typically detected via deviations from the benign profile of water usage. However, profiling the benign behavior is non-trivial for large-scale SWM networks because once deployed, the collected data already contain those events, biasing the benign profile. To address this challenge, we propose a real-time data-driven unsafe event detection framework for city-scale SWM networks that automatically learns the profile of benign behavior of water usage. Specifically, we first propose an optimal clustering of SWMs based on the recognition …

Log Sequence Anomaly Detection Based On Template And Parameter Parsing Via Bert, Xiaolin Chai, Hang Zhang, Jue Zhang, Yan Sun, Sajal K. Das

Computer Science Faculty Research & Creative Works

Logs record various operations and events during system running in text format, which is an essential basis for detecting and identifying potential security threats or system failures and is widely used in system management to ensure security and reliability. Existing log sequence anomaly detection is limited by log parsing and does not consider all key features of logs, which may cause false or missed detection. In this paper, we propose a fast and accurate log parsing method and feed the entire log content into the deep learning network for analysis. To avoid semantic loss during parsing, we replace some variables …

(2024) Justus Buchler And The Community Of Query., Maughn Rollins Gregory

Collected Papers of Maughn Rollins Gregory

Before he originated the field of philosophy for children, Matthew Lipman spent nearly twenty years teaching at Columbia University and its affiliated colleges under the tutelage of the American philosopher Justus Buchler. In those years Lipman’s scholarship focused on Buchler’s naturalist metaphysics, which was informed by Buchler’s scholarship on the philosophy of Charles Peirce. In this essay I relate Lipman’s relationship with Buchler, summarise Buchler’s theory of human judgement, and indicate key parts of that theory that influenced Lipman’s own theory of judgement and multidimensional thinking. I then discuss the pedagogical turn Buchler made with his theory, including his conception …

Correcting Contradiction: Limiting License Suspension As A Child Support Enforcement Mechanism In Pennsylvania, Robin Platte

Dickinson Law Review (2017-Present)

In many communities across Pennsylvania, maintaining employment without a driver’s license is extremely difficult. Section 4355 of the Pennsylvania Domestic Relations Code authorizes license suspension as a means to encourage child support payments. Unfortunately, license suspensions rarely result in obligors making payments. Instead, suspensions often lead to loss of employment and financial insecurity. Under Section 4355, if an obligor falls three months behind in child support payments, their professional, recreational, and driver’s licenses may be suspended indefinitely. Coincidentally, the obligor’s actual ability to pay may not be considered in a pre-suspension hearing. Even those who fall far below the national …

Using State And Local Governments’ Purchasing Power To Combat Wage Theft, Courtlyn G. Roser-Jones

Washington and Lee Law Review

Regulatory efforts to curb wage theft are failing. And for good reason: these laws generally empower individual workers to pursue their rights when employers neglect to pay them what they are owed and deter employers with substantial penalties. But the vast majority of workers do not take formal action against their employers. So, when the penalties for committing wage theft are almost entirely triggered by claims workers do not bring, they do not deter employer behavior. Instead, because the likelihood of being penalized at all is so low, some employers make profit-maximizing decisions to commit wage theft on a large …

Mandatory Sentences As Strict Liability, William W. Berry Iii

Washington and Lee Law Review

Strict liability crimes—crimes that do not require a criminal intent—are outliers in the world of criminal law. Disregarding criminal intent risks treating the blameworthy the same as the blameless.

In a different galaxy far, far away, mandatory sentences—sentences automatically imposed upon a criminal conviction—are unconstitutional in certain contexts for the exact same reason. Mandatory death sentences risk treating those who do not deserve death the same as those that might.

Two completely separate contexts, two parallel rules of law. Yet courts and commentators have failed to see the similarities between these two worlds, leaving an analytical black hole. Indeed, equity …

Partial And Total Tonsillectomy For Pediatric Sleep-Disordered Breathing: The Role Of The Cas-15, Jacob Garn Mabey

Yale Medicine Thesis Digital Library

The Clinical Assessment Score-15 (CAS-15) is an office-based tool for assessing the riskof sleep disordered breathing (SDB), a relatively common condition in the pediatric population. Change in CAS-15 following total tonsillectomy (TT) has been shown to have a large effect size, but it is unclear how it varies following partial intracapsular tonsillectomy (PIT). Thus, the objective of the present study is to evaluate the utility of the CAS-15 score in assessing the effectiveness of PIT and how this compares to change after TT. Children ages 2-18 undergoing PIT (N=16) or TT (N=8) with or without adenoidectomy for SDB completed the …

Establishing Guidelines For Implementing Electronic Hand Hygiene Monitoring Systems, Olaoti Opaleye

Doctor of Nursing Practice (DNP) Scholarly Projects - Archive

Healthcare-associated infections (HAIs) in hospitals threaten patient safety and quality of care, which leads to increased healthcare costs. Despite national and state-level progress in hand hygiene compliance (HHC), the 2022 CDC annual report on HAIs highlighted ongoing concerns for standard infection ratios (SIRs) and called for improved HHC to reduce HAIs. Many hospitals use trained observers to collate HHC data; their audits are limited and often skewed by the Hawthorne Effect (HE) and observer bias, resulting in inaccurate HHC data. This project aimed to create guidelines for implementing electronic hand hygiene monitoring systems (EHHMSs) to help hospital inpatient units adopt …

Does Heightened Perceptual Encoding In Blind Individuals Extend To Word Learning?, Lindsay N. Harris, Marissa Renee Bamberger

CISLL Publications

Past research reported blind participants tend to encode sensory details of encounters with stimuli they will later recall or recollect, whereas sighted individuals tend to abstract meaning from sensory information when encoding memories. Here we ask whether blind individuals’ use of perceptual in addition to semantic encoding extends to a task—word learning—whose purpose amounts to semantically encoding the word and definition. After studying the definitions of spoken or written words, blind braille readers (n = 23) and sighted print readers (n = 20) re-encountered each word and indicated whether it was previously presented in the same modality. Analyses …

Ship Shaping: How Congress And Industry Influenced U.S. Naval Acquisitions From 1933-1938, Henry H. Carroll

Harvey M. Applebaum ’59 Award

Studying shipbuilding politics across time can yield key insights into present-day shipbuilding acquisition reform issues, such as the effects of naval industry consolidation and potential “ally-shoring” of warship production on domestic political support for future naval funding. Past studies of naval acquisitions during the late interwar period often focus on how President Franklin Delano Roosevelt and the Navy Department prepared the nation for the beginning of World War II. However, Congress and the shipbuilding industry played an often-overlooked role in creating the political support needed to expand the Navy during the tumultuous late interwar period. Self-interested domestic interest groups were …

Surveyor: Scratching For A Wild Moon, Nina Grigg

Harvey M. Applebaum ’59 Award

At the dawn of the space race, neither the moon as a destination nor man’s physical presence there were foregone conclusions. In order to get to that all important "first step," NASA had to dissect the Moon as a romantic symbol into concrete ground that space boots could tread on. Identifying these sites on a terrain so uniquely hostile to human habitation required remote exploration mediated by totally encapsulating technology. However, in the attempts of scientists and engineers to objectively explore the lunar wilderness, they unintentionally transformed it into an extension of the urban landscape. Once only conceivable as a …

The study aimed to determine (1) the cut-off points of the drum sampler to better understand its performance characteristics and (2) to investigate indoor air quality, specifically within makerspaces on Bucknell University’s campus. The research highlighted the novelty of applying LA-ICPMS for time-resolved aerosol composition analysis, demonstrating the potential for low-cost pollution concentration studies. The characterization experiments did not yield expected results, but the …

Experimental Evaluation Of Mesh Size In Physically Crosslinked Polymer Gels Using Dynamic Light Scattering, Duncan M. Hill

Honors Theses

Block copolymer gels are under consideration as drug delivery patches. Controlling and modeling the transport inside the gel is an important contribution to the successful delivery of pharmaceuticals. The diffusive transport of a solute – such as a therapeutic compound – within the gel can be described by the mesh size of the gel, which is defined as the distance between polymer chains. Existing experimental evaluations of mesh size do not work for block copolymer gels due to differences in the fundamental gel structure. As such, an experimental method of measuring mesh size of block copolymer gels using dynamic light …

The Precedence-Constrained Quadratic Knapsack Problem, Changkun Guan

Honors Theses

This thesis investigates the previously unstudied Precedence-Constrained Quadratic Knapsack Problem (PC-QKP), an NP-hard nonlinear combinatorial optimization problem. The PC-QKP is a variation of the traditional Knapsack Problem (KP) that introduces several additional complexities. By developing custom exact and approximate solution methods, and testing these on a wide range of carefully structured PC-QKP problem instances, we seek to identify and understand patterns that make some cases easier or harder to solve than others. The findings aim to help develop better strategies for solving this and similar problems in the future.

Evaluating Field Evidence Of Fine-Grained Sediment Abrasion In Gravel-Bedded Rivers: A Case Study Of The Lillooet And Suiattle Rivers In The Cascade Volcanic Arc (British Columbia, Canada, And Washington, Usa), Devin T. Johnson

Honors Theses

Steep, gravel-bedded rivers are important sites for studying gravel abrasion, where material transported as bed load experiences size reduction and rounding due to grain-to-grain collisions. Studying fine sediment (diameter) abrasion and grain shape changes in fluvial systems is more challenging due to difficulties in quantifying sediment shape at this scale, but it is assumed that fine particles traveling in suspension do not experience abrasion. Improvements in particle characterization technology now allow for the accurate, rapid quantification of particle shape for sediments as fine as 0.8 μm through dynamic image analysis. Here we use the Camsizer X2 (CX2) to test the …

Understanding Para-Athlete Inclusion In Post-Secondary Athletics, Rayven J. Sample

Honors Theses

This qualitative study utilized thematic analysis of six interviews with elite Para-athletes who were currently enrolled at a four-year undergraduate institution and were actively competing or training in any Para-sport to understand inclusion of Para-athletes within the NCAA. This investigatory research sought to identify barriers present in the NCAA’s structure and advocate for positive change as more Para-athletes desire to access collegiate athletic resources due to increasingly higher standards of performance within Para-sport. Para-athletes discussed five key themes during interviews; “Disability Mindset” or the way athletes conceptualized their presence within the athletic environment; sources of education available to athletics staff …

Examining The Relationship Between Subclinical Borderline Personality Disorder And Social Support Networks, Gabriella D'Alicandro

Honors Theses

The purpose of my study was to investigate the relationship between subclinical Borderline Personality Disorder and social support in situational measures such as social provisions, network size, and network satisfaction as well as dispositional measures such as support seeking and socially supportive behaviors. I hypothesized that BPD scores would be negatively correlated with all dispositional support measures. I also predicted that in situational support measures, BPD would have a negative correlation. I hypothesized when confronted with romantic stressors participants would receive more support when confounded with the workplace stressors. Participants (N= 178; 146 women 28 men, 3 nonbinary individuals, and …

Rethinking The Fundamentals: Applying The Evolving Standards Of Decency Test To The Court’S Evaluation Of Fundamental Rights, Nick Wolfram

Student Scholarship

In 1910, the Supreme Court recognized in Weems v. United States that a constitution “must be capable of wider application than the mischief which gave it birth.” This principle led to the creation of the Court’s two-pronged “evolving standards of decency,” test: (1) evidence of an objective indicia of a national consensus, and (2) the reviewing court’s own independent judgment. To this day the Court has yet to apply this test outside of the Eighth Amendment context. But can the “evolving standards of decency,” test identify and protect other fundamental rights? This Article explores how the Court could apply the …

Diagnostic Utility Of Chest Radiographs In Children With Clinically Diagnosed Pneumonia As Per The Kenya Basic Paediatric Protocol, Ivy Waruguru Wakahora

Master of Medicine in Imaging and Diagnostic Radiology

Introduction; Pneumonia causes significant morbidity and mortality in children globally, emphasizing the need for accurate diagnosis. While chest radiographs have traditionally been the gold standard for diagnosis, recent international guidelines discourage their routine use in paediatric community acquired pneumonia (pCAP). Despite this, chest radiographs are still regularly acquired for pneumonia diagnosis, resulting in practice variations and imaging overutilization. This study aims to evaluate the diagnostic utility of chest radiographs in children with clinically diagnosed pneumonia as per the Kenya Basic Paediatric Protocol (KBPP).
