Locality-Aware Qubit Routing For The Grid Architecture, Avah Banerjee, Xin Liang, R. Tohid Jan 2022

Locality-Aware Qubit Routing For The Grid Architecture, Avah Banerjee, Xin Liang, R. Tohid

Computer Science Faculty Research & Creative Works

Due to the short decohorence time of qubits available in the NISQ-era, it is essential to pack (minimize the size and or the depth of) a logical quantum circuit as efficiently as possible given a sparsely coupled physical architecture. In this work we introduce a locality-aware qubit routing algorithm based on a graph theoretic framework. Our algorithm is designed for the grid and certain 'grid-like' architectures. We experimentally show the competitiveness of algorithm by comparing it against the approximate token swapping algorithm, which is used as a primitive in many state-of-the-art quantum trans pilers. Our algorithm produces circuits of comparable …


Privacy-Preserving Data Falsification Detection In Smart Grids Using Elliptic Curve Cryptography And Homomorphic Encryption, Sanskruti Joshi, Ruixiao Li, Shameek Bhattacharjee, Sajal K. Das, Hayato Yamana Jan 2022

Privacy-Preserving Data Falsification Detection In Smart Grids Using Elliptic Curve Cryptography And Homomorphic Encryption, Sanskruti Joshi, Ruixiao Li, Shameek Bhattacharjee, Sajal K. Das, Hayato Yamana

In an advanced metering infrastructure (AMI), the electric utility collects power consumption data from smart meters to improve energy optimization and provides detailed information on power consumption to electric utility customers. However, AMI is vulnerable to data falsification attacks, which organized adversaries can launch. Such attacks can be detected by analyzing customers' fine-grained power consumption data; however, analyzing customers' private data violates the customers' privacy. Although homomorphic encryption-based schemes have been proposed to tackle the problem, the disadvantage is a long execution time. This paper proposes a new privacy-preserving data falsification detection scheme to shorten the execution time. We adopt …


Rssafe: Personalized Driver Behavior Prediction For Safe Driving, Bhumika, Debasis Das, Sajal K. Das Jan 2022

Rssafe: Personalized Driver Behavior Prediction For Safe Driving, Bhumika, Debasis Das, Sajal K. Das

Computer Science Faculty Research & Creative Works

While the increased demand for taxi services like Uber, Lyft, Hailo, Ola, Grab, Cabify etc. provides livelihood to many drivers, the desire to raise income forces the drivers to work very hard without rest. However, continuous journeys not only affect their health, but also lead to abnormal driving behavior such as rash driving, swerving, sideslipping, sudden brakes, or weaving, leading to accidents in the worst cases. Motivated by the severity of rising accidents and health issues among drivers, this paper proposes a recommendation system, called RsSafe, for the safety of drivers. Aiming to improve the driving quality and the driver's …

Modern smart cities are focusing on smart transportation solutions to detect and mitigate the effects of various traffic incidents in the city. To materialize this, roadside units and ambient trans-portation sensors are being deployed to collect vehicular data that provides real-time traffic monitoring. In this paper, we first propose a real-time data-driven anomaly-based traffic incident detection framework for a city-scale smart transportation system. Specifically, we propose an incremental region growing approximation algorithm for optimal Spatio-temporal clustering of road segments and their data; such that road segments are strategically divided into highly correlated clusters. The highly correlated clusters enable identifying a …


Leveraging Spanning Tree To Detect Colluding Attackers In Federated Learning, Priyesh Ranjan, Federico Coro, Ashish Gupta, Sajal K. Das Jan 2022

Leveraging Spanning Tree To Detect Colluding Attackers In Federated Learning, Priyesh Ranjan, Federico Coro, Ashish Gupta, Sajal K. Das

Computer Science Faculty Research & Creative Works

Federated learning distributes model training among multiple clients who, driven by privacy concerns, perform training using their local data and only share model weights for iterative aggregation on the server. In this work, we explore the threat of collusion attacks from multiple malicious clients who pose targeted attacks (e.g., label flipping) in a federated learning configuration. By leveraging client weights and the correlation among them, we develop a graph-based algorithm to detect malicious clients. Finally, we validate the effectiveness of our algorithm in presence of varying number of attackers on a classification task using a well-known Fashion-MNIST dataset.


Fadeloc: Smart Device Localization For Generalized Κ-Μ Faded Iot Environment, Ankur Pandey, Piyush Tiwary, Sudhir Kumar, Sajal K. Das Jan 2022

Fadeloc: Smart Device Localization For Generalized Κ-Μ Faded Iot Environment, Ankur Pandey, Piyush Tiwary, Sudhir Kumar, Sajal K. Das

Computer Science Faculty Research & Creative Works

In this paper, we propose FadeLoc a novel method for localizing smart devices in an Internet of Things (IoT) environment, based on the Received Signal Strength (RSS), and a generic κ-μ fading model where κ and μ denote the fading parameters. The RSS-based localization is challenging because of noise, fading, and non-line-of-sight (NLOS) effects, thus necessitating an appropriate fading model to best fit the varying RSS values. The advantage of a generic fading model is that it can accommodate all existing fading distributions based on the estimate of κ and μ. Hence, the localization can be performed for any fading …


Action-Centric Relation Transformer Network For Video Question Answering, Jipeng Zhang, Jie Shao, Rui Cao, Lianli Gao, Xing Xu, Heng Tao Shen Jan 2022

Action-Centric Relation Transformer Network For Video Question Answering, Jipeng Zhang, Jie Shao, Rui Cao, Lianli Gao, Xing Xu, Heng Tao Shen

Research Collection School Of Computing and Information Systems

Video question answering (VideoQA) has emerged as a popular research topic in recent years. Enormous efforts have been devoted to developing more effective fusion strategies and better intra-modal feature preparation. To explore these issues further, we identify two key problems. (1) Current works take almost no account of introducing action of interest in video representation. Additionally, there exists insufficient labeling data on where the action of interest is in many datasets. However, questions in VideoQA are usually action-centric. (2) Frame-to-frame relations, which can provide useful temporal attributes (e.g., state transition, action counting), lack relevant research. Based on these observations, we …


(2022) Philosophizing With Children’S Literature: A Response To Turgeon And Wartenberg, Darren Chetty, Maughn Rollins Gregory, Megan Jane Laverty Jan 2022

(2022) Philosophizing With Children’S Literature: A Response To Turgeon And Wartenberg, Darren Chetty, Maughn Rollins Gregory, Megan Jane Laverty

Collected Papers of Maughn Rollins Gregory

With the maturation of a field comes the opportunity and the responsibility to reflect on its sources, its areas and directions of development, debates among its proponents, and critiques originating from inside and outside the field. While early proponents of philosophy for children supported each other in the face of misunderstanding and misapprehension, differences inevitably arose among them, not only concerning materials and methods, but also concerning the very meanings of philosophy, childhood and education. These differences remain among contemporary scholars, educators and practitioners, who continue to engage in robust debates about how to research and practice philosophy with children …

The Leveling Spirit: Violence And Inequality In Postwar Iraq, Griffin Perrault Jan 2022

The Leveling Spirit: Violence And Inequality In Postwar Iraq, Griffin Perrault

Honors Theses

The Iraq War (2003–2011) constitutes by some estimates one of the deadliest and most destructive conflicts of the 21st century (Hagopian et al., 2013). In addition to the disputed figures of excess violent civilian casualties––generally ranging from 180,000 to 210,000 deaths––the war has created one of the major refugee crises of modern times, with 1 in 25 Iraqis estimated to have been displaced from their homes by the 2003 invasion (Costs of War, 2021). While much of this violence has been wrought by American and Iraqi coalition troops, violence against civilians has also been perpetuated by insurgent groups and paramilitary …


Winner And Loser Effects In Madagascar Hissing Cockroaches (Gromphadorhina Portentosa), Casey Mack Jan 2022

Winner And Loser Effects In Madagascar Hissing Cockroaches (Gromphadorhina Portentosa), Casey Mack

Honors Theses

Winner and loser effects have been documented in many species throughout the animal kingdom, but have yet to be investigated in Madagascar hissing cockroaches. This study seeks to determine if winner or loser effects are present in Madagascar hissing cockroaches. In Experiment 1, three subjects won a training contest and three subjects lost a training contest. Training contest winner and training contest loser subjects were then paired up in test contests. Four of the 6 subjects showed test contest outcomes consistent with their training contest outcomes, but the overall conclusions were ambiguous due to the small sample size. Whether the …


A Contraction Based Approach To Tensor Isomorphism, Anh Kieu Jan 2022

A Contraction Based Approach To Tensor Isomorphism, Anh Kieu

Honors Theses

Tensor isomorphism is a hard problem in computational complexity theory. Tensor isomorphism arises not just in mathematics, but also in other applied fields like Machine Learning, Cryptography, and Quantum Information Theory (QIT). In this thesis, we develop a new approach to testing (non)-isomorphism of tensors that uses local information from "contractions" of a tensor to detect differences in global structures. Specifically, we use projective geometry and tensor contractions to create a labelling data structure for a given tensor, which can be used to compare and distinguish tensors. This contraction labelling isomorphism test is quite general, and its practical potential remains …

Evaluating The Relationship Between Floodplain Topography And Channel Avulsion: Evidence From The Devonian Catskill Formation, North-Central Pennsylvania, Usa, Molly O'Halloran Jan 2022

Evaluating The Relationship Between Floodplain Topography And Channel Avulsion: Evidence From The Devonian Catskill Formation, North-Central Pennsylvania, Usa, Molly O'Halloran

Honors Theses

Topographic complexity on floodplains can route flow, control sediment dispersal, and influence channel behavior, but studying floodplain-channel interactions in modern rivers is challenging because of human modifications and the short timescales of observable data. This project assesses the link between different types of floodplain microtopography and avulsion style in the Devonian Catskill Formation, north-central Pennsylvania, where thick stacks of fluvial strata provide a lengthy record of channel-floodplain interaction. Using a combination of field observations and computer modeling, this study identifies sedimentary features indicative of floodplain complexity and analyzes their impact on avulsion style at fourteen Catskill Formation outcrops.

Based on …


Where Girls Rule The World: Lessons For Pakistan In The Bangladeshi Educational Phenomenon, Chanze Ahsan Jan 2022

Where Girls Rule The World: Lessons For Pakistan In The Bangladeshi Educational Phenomenon, Chanze Ahsan

Honors Theses

In tune with the UN's Sustainable Development Goal and the widespread acceptance of education as a fundamental human right, the deprivation of female education in Pakistan presents an alarming assault on its female population. With this, the historical accident that was the separation of Pakistan and Bangladesh serves as a natural experiment into differences between the countries before and after partition. Despite facing two colonizations, Bangladesh has emerged on the other side of history with promising results regarding the elimination of gender disparities in education. How has it managed to do so? And what can Pakistan learn from its journey? …


The Impact Of The Covid-19 Pandemic On Corporate Financial Fragility In The Vietnamese Manufacturing Industry, Trang Nguyen Jan 2022

The Impact Of The Covid-19 Pandemic On Corporate Financial Fragility In The Vietnamese Manufacturing Industry, Trang Nguyen

Honors Theses

In the past decades, under the government’s export-led growth strategy, the Vietnamese manufacturing sector – the backbone of the whole Vietnamese economy – has established a deep tie with the international market and the reliance on foreign buyers has fueled the growth of this sector before COVID-19. However, during the pandemic, when the global market contracted at -3.5 percent and demand slumped globally, this existing growth model and the manufacturing sector’s reliance on foreign buyers induced significant risks to this sector from both the demand and supply side. Using the firm-level data on 41 manufacturing exporting companies from the Vietstock …


Supporting Teacher Retention Through A Trauma-Informed Lens, Nicole C. Reddig Jan 2022

Supporting Teacher Retention Through A Trauma-Informed Lens, Nicole C. Reddig

Honors Theses

This thesis explores the relationship between trauma-informed practices and teacher burnout and turnover. For the past decade, schools across the United States have seen high levels of burnout and turnover amongst their educators. At the same time, young children are experiencing high levels of exposure to traumatic events in childhood, affecting their behavior, social and emotional health, and ability to learn. While teachers play an important role in the support system for these students, they are also at risk for experiencing secondary trauma and burnout. To mitigate the effects of trauma, trauma-informed practices have been introduced in schools to respond …

Dynamics Of Targeted Ransomware Negotiation, Pierce Ryan, John Fokker, Sorcha Healy, Andreas Amann Jan 2022

Dynamics Of Targeted Ransomware Negotiation, Pierce Ryan, John Fokker, Sorcha Healy, Andreas Amann

Research Outputs: 2025-Present

In this paper, we consider how the development of targeted ransomware has affected the dynamics of ransomware negotiations to better understand how to respond to ransomware attacks. We construct a model of ransomware negotiations as an asymmetric non-cooperative two-player game. In particular, our model considers the investments that a malicious actor must make in order to conduct a successful targeted ransomware attack. We demonstrate how imperfect information is a crucial feature for replicating observed real-world behaviour. Furthermore, we present optimal strategies for both the malicious actor and the target, and demonstrate how imperfect information results in a non-trivial optimal strategy …


Melatonin As An Immunomodulator In Children With Down Syndrome, Dean Huggard, Lynne Kelly, Amy Worrall, Eleanor Gallagher, Lida Fallah, Lucas Lu Yoo, Fiona Mcgrane, Niamh Lagan, Edna Roche, Joanne Balfe, Derek G. Doherty, Eleanor J. Molloy Jan 2022

Melatonin As An Immunomodulator In Children With Down Syndrome, Dean Huggard, Lynne Kelly, Amy Worrall, Eleanor Gallagher, Lida Fallah, Lucas Lu Yoo, Fiona Mcgrane, Niamh Lagan, Edna Roche, Joanne Balfe, Derek G. Doherty, Eleanor J. Molloy

Research Outputs: 2025-Present

Background: Down syndrome (DS) is a disorder characterised by marked immune dysfunction, increased mortality from sepsis, chronic inflammation, increased oxidative stress, sleep disturbance and possibly abnormal endogenous melatonin levels. Melatonin has a myriad of immune functions, and we hypothesised that this therapeutic agent could modulate the innate immune system in this cohort. Methods: We investigated neutrophil and monocyte function (CD11b, TLR4 expression by flow cytometry), genes involved in TLR signalling (MyD88, IRAK4, TRIF), the inflammasome (NLRP3, IL-1β), and circadian rhythm (BMAL, CLOCK, CRY) by qPCR, and inflammatory cytokines (IL-2, IL-6, IL-8, IL-18, IL-1β, TNF-α, IFN-γ, IL-10, IL-1ra, VEGF, Epo, GM-CSF) …
