description: Natural disasters cause personal injuries, and financial hardship for the whole society. Due to climate change the incidents of natural disasters are increasing with higher intensity. During and even immediately after a natural disaster an assessment of the impacted area is crucial to the rescue team to provide the necessary and immediate help. We can utilize the recent advancement in the field of computer vision to extract essential information in this scenario and provide important help in rescue efforts. Despite the urgency and the importance of application of computer vision techniques in this field there is not much research and resources available. This thesis focuses on the developing datasets and methodologies for natural disaster damage assessment. This thesis presents two datasets with pixel-level annotation named FloodNet and RescueNet. The images of FloodNet were collected after hurricane Harvey while RescueNet is built upon the images collected after hurricane Michael. Before the creation of RescueNet, an initial version was released as HRUD. FloodNet consists of 9 classes and RescueNet includes 10 classes including 4 different building damage classes. We also developed two self-attention based semantic segmentation methods and implemented them on the developed datasets. The developed methods have shown superior performance on these two datasets compared to other state-of-the-art semantic segmentation methods. However, the developed supervised segmentation models are heavier in size and therefore not suitable for edge device implementation for real-world application. In future, we intend to reduce the model complexity and design more lighter models for ease of edge device implementation. Despite higher accuracy attained by the developed methods, scarcity of labeled images in the datasets is a roadblock for developing deep learning methods. Recent deep learning methods require a lot of data to train the models. Semi-supervised learning can be utilized in this scenario. Although semi-supervised learning is getting popular in the computer vision community, there has not been much work done in terms of semantic segmentation. In this thesis, we develop a semi-supervised semantic segmentation method implementing consistency regularization. The detailed experimental analysis shows that our developed semi-supervised performed better existing state-of-the-art semi-supervised methods and can further improve the accuracy of segmentation using unlabeled data. Despite improvement upon supervised methods, semi-supervised methods still suffer from distribution between the labeled and unlabeled data while applying unlabeled data in the training process and degrade the results. In future, we intend to address the distribution shift and class imbalance in the dataset during the model development.

description: Advances in machine learning have recently found success in automating common malware analysis tasks. Historically, two of the primary challenges in implementing a machine learning model for use in a malware analysis environment have been selecting representative malware features and identifying a high-confidence source of malware labels. Both of these are made more difficult due to the massive quantity and diversity of malicious files, as well as the adversarial nature of malware analysis. Many existing malware featurization approaches are only feasible at small scales, can only be applied to a single file format, or are defeated by common obfuscation techniques. Malware datasets have long suffered from label quality issues, and datasets with ground-truth labels are severely restricted in both size and diversity. In this dissertation, we explore the utility of antivirus scan reports, which are the results obtained by scanning a malicious file with a collection of antivirus products. Antivirus products may identify malware using a variety of approaches (byte signatures, heuristics, dynamic analysis, etc.) and their outputs contain diverse information (including file format, behavior, malware family, packer, and vulnerability information). We show that due to this diversity, antivirus scan reports have promising utility as a source of features for multiple types of supervised and unsupervised learning, and as a source of labels for multiple common malware classification tasks.

Measuring Risks of Organizational Failure in Contract Exchange Structures
Creators: name: Carboni, Julia L.
Publisher: name: University of Bamberg Press
Year: 2015
Subjects: contracting; networked exchange; affiliation networks; governance structures.

description: Governmental agencies increasingly contract out service delivery, but have little understand- ing of the systemic risk associated with dependence on contractors in service delivery networks. In this study, affiliation network concepts are used to develop a structural index of government dependence on actors in service delivery networks without joint service delivery. Networks in- clude direct links to government funders and indirect links among contracted programs based on shared parent organizations. Understanding the structure of governance arrangements has practical implications for governance, in terms of understanding government dependence on a particular contractor and the risk associated with organizational failure of those contractors. Governance structures may also influence individual incentives to perform. This study makes two contributions to the governance literature. First, the study offers conceptualization of con- tracted programs as networked structures of exchange even where joint production does not oc- cur. Second, an index is proposed to capture the position of individual organizations in complex networks of exchange with government. This index can be used to determine the dependence of government on a specific actor in the service delivery network along with the risk to the network should a particular organization fail. This index can also be incorporated into statistical models of contract performance.

description: Quantum computing allows for significant speed-up in solving certain practical problems as compared to classical computing. The current quantum computers are limited by high error rates and a limited number of qubits, quantum bits. Silicon spin qubits, the main focus of this dissertation, are a promising platform for quantum computing that also suffers from these issues. Current silicon spin quantum computers are limited in size and error rates by charge noise. The goal of this dissertation is to develop quantum control methods that can create high-fidelity gates, low-error rate operations, and scale these gates to larger qubit systems. To this end, in the first half of the dissertation numerical optimization methods are presented that create robust gates in 2-3 qubit systems. This is expanded in the later half where a method for creating robust gates in arrays of Ising coupled qubits is presented. Finally, a method to supplement robust gates by measuring charge noise in situ was proposed in the final work presented in this dissertation. The methods developed in this dissertation help move quantum computing toward becoming practical.

description: Governance networks are both nested and interconnected systems. Identifying internal boundaries within governance networks, such as those governance structures that influence and are influenced by large and diverse watersheds such as the Lake Champlain Basin, is necessary for differentiating between multiple functional subnetworks. Internal network boundaries exist between functional subnetworks when the networks have divergent structures (Weible & Sabatier, 2005). A qualitative case study of Lake Champlain Basin watershed governance networks identified several key overlapping subnetworks in which organizations interact in a variety of ways (Koliba, Reynolds, Zia, & Scheinert, 2015). An online survey of institutional actors was used to identify which actors were connected in five different functional subnetworks. Structural comparisons are made by analyzing the correlation between the subnetworks based on the quadratic assignment procedure (QAP) and network macrostructure. Results show that the information sharing, technical assistance, and project collaboration subnetworks formed one grouping, while the reporting and financial resource sharing subnetworks formed another grouping. The results demonstrated that this triangulated comparison was necessary to reach valid conclusions on the structural variation between the subnetworks on a multiplex network when subnetworks were structurally similar.

description: This ethnographic dissertation research project focuses on a digital storytelling workshop called Food/Stories which took place in collaboration with Black Yield Institute in Spring of 2023. The Food/Stories workshop is the case study that I used to explore the effectiveness of Collaborative Visual Storytelling, a methodological approach that provides a road map for university-based research practitioners to collaborate ethically with community organizations and individuals towards mutually agreed upon goals, using visual research tools. This inquiry included a deep exploration of the ethics of engagement, an attention to process over product, the use of story circles to foreground conversations about lived experiences with the food system, and digital storytelling as the primary visual research tool. The research combines elements of Critical Participatory Action Research and Participatory Visual Methods and is rooted in Black feminist and Indigenous epistemologies which center the lived and embodied experiences of marginalized people in the creation of knowledge and for whom relationship is central to the research process. I argue for the use of Collaborative Visual Storytelling in social movements and community partnerships wherein university-based practitioners and community members work toward a community-identified goal, utilizing visual tools. The data in this project demonstrate that relationality is and must be central to community-university collaborations, that existing power dynamics need to be addressed, that process is as important as product, and that projects must move only as quickly as trust can develop. This project has implications for the way that universities and their surrounding communities might engage with one another in ways that are collaborative, rooted in a strong consideration of ethics, and which pursue mutually beneficial outcomes.

Home New World

Publisher: name: Maryland Shared Open Access Repository
Year: 2024

description: Home New World is a self-portrait that delves into the liminal space of my 13-year-old self recently arrived in a new country. My inspiration for this project stems from challenges in my current life, including fatherhood and ailing parents. These experiences led me to reexamine that transitional period of assimilation, recollecting memories of when everything around me appeared new and unfamiliar, almost as if I were being newly born. I believe that creating art through lived experiences, and drawing inspiration from the events that unfold in everyday life reveals a path toward self-transformation.My work consists of fragmented memories presented through a series of drawings and related floating objects in the form of mobiles, set within an environment of looping video projection and sound. Each drawing and its corresponding object carry significant personal anecdotes. In the gallery the objects move kinetically, mirroring the properties of memories: fading in and out, stacking on top of one another, and blending the forgotten with the remembered. Their shadows fall onto a looping carousel of painted suburban homes. This written thesis is structured to emulate the mobile organization of Home New World. Whereas writing unfolds sequentially, the experience of visual art is “all at once.” That is, often there is no prescribed entry point to the work. To remain authentic to my artwork, I have persisted in attempting to structure the written thesis to intuitively mimic the layered, fragmented, and disorienting aspects of my artwork. This memoir is composed of whimsical anecdotes strung together and interspersed with theoretical insights and artistic influences on my creative process. Each anecdote represents a memory associated with a significant object, revealing glimpses of the past. These stories weave together, fading in and out of focus, creating a non-chronological sequence that reflects my past life in contemplation of the present.?

Sustainable Preservation: The Adaptive Reuse of Historic Industrial Buildings and Spaces in Baltimore City, 1970-2020
Creators: name: Masser, Joshua Paul

Year: 2024
Subjects: Adaptive Reuse

Historic Preservation

description: This thesis demonstrates that the preservation and adaptive reuse of historic industrial buildings and spaces in Baltimore City from 1970 to 2020, reflects a citywide effort to reinvent the image of Baltimore in the wake of deindustrialization. To do so, it assesses and compares completed and proposed projects across the city; specifically, the Pratt Street Power Plant at the heart of the Inner Harbor, the Meadow Mill in Woodberry, and the Hendler Creamery in Jonestown. This topic is significant because it recognizes Baltimore’s legacy as a historic city that has both inadvertently and consciously became a world leader in cultural and heritage preservation. Despite the successes of the late twentieth century, this thesis argues that Baltimore City officials failed to maintain a commitment to the preservation of the city’s historic industrial character, instead enabling developers to dictate the trajectory of preservation in the twenty-first century.

Enlargement of microcrack

description: We perform theoretical simulation to evaluate the role played by a microcrack in tumors on the overall flow resistance during convection enhanced delivery (CED) of nanofluid in tumor treatment. Both Darcy’s law and theory of poroelasticity are used in the simulation to understand the fluid transport with or without microcrack introduction and/or enlargement. The results have demonstrated significantly altered pressure and velocity fields in the tumor due to introduction of the microcrack. The non-uniform fluid pressure field enlarges the cylindrical microcrack to a frustum, with a crack volume more than doubled. Due to the large permeability and porosity in the microcrack, flow from the infusion surface to the tumor periphery is much easier. The flow resistance with the enlarged microcrack is reduced by 14% from the baseline case without microcrack. We conclude that introducing a microcrack is an effective way to facilitate fluid flow in porous tumors using CED.

description: In der vorliegenden Arbeit werden die Wichtigkeit der Partizipation von Kindern im Fremdplatzierungsprozess aufgezeigt und relevante Aspekte der Sozialen Arbeit für die Umsetzung dieses Rechts dargestellt. Nach einer theoretischen und normativen Vertiefung und der Darlegung von aktuellen Forschungsergebnissen folgt ein praktischer Zugang zur Umsetzung. Die konkrete Fragestellung lautet: Wie können Kinder im Alter von 6-12 Jahren von Fachpersonen der Sozialen Arbeit partizipativ in den Fremdplatzierungsprozess miteinbezogen werden? Kinder sollen im Kontext von Fremdplatzierungen angemessen partizipieren können. Durch Partizipation kann der Problematik der Fremdbestimmung entgegengewirkt werden, indem sich Kinder im Prozess zu selbständigen Akteuren und Akteurinnen entfalten. Gemäss Forschungsergebnissen wissen Kinder bis heute kaum über die Platzierungsgründe Bescheid. Fachleuten ist unklar, wie sie Kinder im Prozess miteinbeziehen können, da klare Konzepte und Handlungsanweisungen fehlen. Damit Kinder eine Chance zur Teilhabe im Platzierungsprozess haben, müssen Fachleute sie angemessen informieren, ihnen aktiv zuhören und sie zu Beteiligung ermächtigen. Dies bedingt die Bereitschaft der Erwachsenen, Kontrolle abzugeben. Qualitätsstandards und Instrumente für partizipative Prozesse müssen zudem als verbindlich erklärt werden und Partizipation bedarf einer Verankerung in den Organisationsstrukturen. Beteiligungsmethoden sollten differenziert und an das einzelne Kind angepasst sein. Das Kind darf nicht unter- oder überfordert werden. Kinderpartizipation beansprucht eine klare und offene Kommunikation, bei welcher auch Grenzen der Beteiligung transparent gemacht werden.

description: To support natural language understanding in research, we aim to build upon previous research that was done by Traum et al, Gervits et al., and Marge et al. where previous experiments were done to create a classifier-based approach to automate human-robot dialog in an urban search and rescue scenario. Their experiments led to collecting a corpus of data called SCOUT (Situated Corpus of Understanding Transactions) along with building a classifier using the NPCEditor platform to build an effective question-answering conversational system. In previous experiments, four in total, a remote autonomous robot was used to collect the data used to build the corpus. This robot and the environment in which the experiments occurred were physical in experiments 1 and 2 but simulated in experiments 3 and 4. Human volunteers termed “Commanders”, would interact with the robot via two Wizards of Oz (WOZ), a Dialog Manager (DM), and a Robot Navigator (RN), performing the task of getting commands and responses between the commander and the robot. We aim to use the aforementioned SCOUT data to train two machine-learning models using the Bag-Of-Words method for featurization, with a random forest classifier and with a Neural Network using word embeddings. Where the “commander” statements are features and the final commands given to the robot navigator, are the labels. The results from both experiments will be compiled and analyzed with the ultimate goal of eliminating the use of Wizard-of-Oz methods that were used in the original four experiments.

Creators: name: Saeki-Serna, Victoria
Publisher: name: Rice University
Year: 2022

description: This thesis analyzes Mexico's foreign policy regarding Cold War era developments in Cuba and the United States' response to said policy. It finds that while Mexico oftentimes defied the anticommunist agenda the United States pushed on to Latin America during this period, it did so not as an immediate affront to the United States, but rather to keep a fragile balance among a broad domestic coalition vital to the Institutional Revolutionary Party (PRI). The United States - though initially upset by the foreign policy of Mexico - eventually understood and accepted the domestic considerations behind its neighbor's foreign policy, as it secured the hold of the PRI in Mexico and thus excluded communists from holding significant political power in that country.

description: This thesis presents kinematics analysis, 3D visualization tool, and motion-force controller for a six degree-of-freedom serial robotic manipulator. Denavit-Hartenberg (DH) convention and Cyclic Coordinate Descent (CCD) are chosen to be the frameworks of forward and inverse kinematics, respectively. The limitation of the existing CCD is identified, wherein the robot can be locked at the singular conditions, and consequently fails to reach the target. After analyzing and categorizing the singularity conditions, an unlock mechanism is developed on top of the conventional CCD to avoid singularity. The dynamics of the manipulator is analyzed using Lagrangian method to implement a motion-force controller. The objectives of a motion-force controller in an environment with obstacles are analyzed to develop a unified control algorithm for trajectory tracking and force control in the same direction. Numerical simulations, and digital twin visualization developed in VxSIM verify that the singularity-free CCD and the controller design are valid.
Conducting Content Analysis of Documents in Network Research: A Review of Recent Scholarship

Publisher: name: University of Bamberg Press
Year: 2015
Subjects: Documents; content analysis; network analysis; network scholarship

description: In this study I examine how researchers have conducted content analysis of documents to collect and analyze network data in public administration. Content analyses of documents help us understand the contexts and meanings of network ties. Researchers can also analyze docu- ments to examine the changes of network ties over time. The types of documents that researchers have used to draw network data are diverse, but the ways they are used are limited. The majority of articles reviewed for this study focused on drawing interorganizational collaboration data, whereas in a few articles content analysis was conducted to draw policy network data. In this study I found that most of the existing network research has converted qualitative data extracted from documents to numerical data for quantitative analysis and has not fully taken advantage of the qualitative data. Researchers can also benefit from providing explicit coding rules and proce- dures to ensure the quality of network data collection.

description: Attitude filtering is a critical technology with applications in diverse domains such as aerospace engineering, robotics, computer vision, and augmented reality. Although attitude filtering is a particular case of the state estimation problem, attitude filtering is uniquely challenging due to the special geometric structure of the attitude parameterization. This thesis presents a novel data-driven attitude filter, called the retrospective cost attitude filter (RCAF), for the SO(3) attitude representation. RCAF uses a multiplicative correction signal computed using retrospective cost optimization and measured data. The RCAF filter is numerically and experimentally validated in a scenario with noisy attitude measurements and noisy and biased rate-gyro measurements.

description: Lorentz symmetry is a cornerstone of both the General relativity and Standard Model and its experimental verification deepens our understanding of nature. This paper focuses on the investigation of Lorentz violations with the context of clock comparison experiments in the framework of Standard Model Extension (SME). Considering matter-gravity coupling sector, we provide a generic frame to study the sensitivities of Lorentz-violating coefficients for three distinct types of clock redshift tests, including the traditional gravitational redshift test, null-redshift test I and null-redshift test II. Each of these tests is sensitivity to different combinations of Lorentz-violating coefficients. By using the current clock comparison results, we estimate the limits of SME coefficients at level of parts in $10^{4}$ down to parts in $10^{7}$. Better sensitivity may be achieved in the clock comparisons by using the state-of-the-art optical clocks. Additionally considering relativistic factors in null-redshift I, the frequency comparison result of E2 and E3 transitions of Yb$^{+}$ can set the limit $c^{e}_{00}=(7.4\pm9.3)\times10^{-9}$ in the electron sector. Our analysis demonstrates that clock-comparison redshift experiments may contribute to explore the vast parameters space on searching for the Lorentz violation.

description: My artistic vision for In Praise of the Unknown embodies a profound inner quest intertwined with my physical journeys across diverse cultures and landscapes. The installation mirrors the complexity of my personal journey, oscillating between the individual self and the collective synthesis of cultural influences. Embracing the diasporic condition, In Praise of the Unknown is an empowering journey, a celebration of the inherent power of the self within the "other." I embody this sense of otherness rooted in my experience within a patriarchal system, extending it through my perspectives during my nomadic travels to present an unfamiliar state of metamorphosis. As a woman born in Iran, I've experienced secondary status to men. My focus on diaspora and liberation, therefore, unfolds through the deconstruction, displacement, and transformation of my female body, redefining otherness as a source of empowerment and challenging conventional victim narratives.

description: The purpose of this qualitative study was to explore the intersection of familial and school-based racial–ethnic socialization of mixed-race children in suburban schools. Suburban schools provide educational services to most youth in the United States and a growing number of mixed-race families. This dissertation focused on how parents prepare children to navigate racialized school experiences and the impact of their decisions on the racial knowledge development of multiracial youth, the fastest-growing racial demographic under 18.Critical multiracial theory was the theoretical lens used to present findings through storytelling, allegories, and narrated dialogue. The findings showed that parents strategically chose where to live and which schools to send their children. The findings suggest varying parental efforts in cultivating awareness of race based on children’s racial background and appearance. Parents may struggle to address issues of racism, racial stratification, and discrimination due to their perceptions of residing in a good community with good schools. Although young people might downplay the significance of racism in their lives, many acknowledge the subtle impact of systemic racism on their school experiences. The study found structural barriers, such as academic tracking and school zoning, to access to peers from minoritized heritage groups. However, minoritized peers are critical for fostering positive racial–ethnic identities at school. Findings also suggest that young people’s inability to identify the structural elements of everyday racism could relate to the lack of multiracial representation and the neglect of structural and systemic racism in formal curricula. The study could have implications for parents, school leaders, young people, and scholars of racial–ethnic socialization and suburban education.
A State That Leaves No One Behind? Erasure of Native Peoples in Maryland & How This Limits Inclusive Environmental & Climate Action

description: “A State That Leaves No One Behind,” was a bold statement from current Governor Wes Moore when he was campaigning for the governor position. However, his statement did not hold true considering Maryland Tribal communities that are still being left behind. Why? It could be because of their Tribal status. The state of Maryland has no federally recognized Tribes. Out of six Tribes that are ancestral to this region, only three are state-recognized I had to ask, who are the Tribal Peoples of Maryland? As a graduate student originally from Arizona, I did not know that Tribes that are ancestral to the Chesapeake Bay region were still here and other Tribes have migrated to this region that call it home. I later learned that the main reason why erasure started in the first place. I and others assumed that Tribal Peoples continue to thrive in the Chesapeake Bay region is because of historical documentations from the colonial governments that were purposely biased and did not document the whole truth of the presence of numerous Tribal Nations still residing in colonial state borders of what is now called Maryland. It didn’t help that the academia supported their documentations because they have the highest credentials and were historical figures that made progression of this country, the United States. You might think that Indigenous erasure is a thing of the past and it not currently happening. Wrong. It’s still weaving through our societies and systems. For instance, if you Google “Native American” or “Indigenous Peoples” or “Tribal Peoples” in the search engine you will notice that there is a lot of historical information and pictures available but little to no pictures of current Tribal Peoples. Another example are the history books used by our education systems that are told from a Eurocentric perspective and the terminologies they use for Tribal Peoples is past-tense. No present or future tense terminologies or information are included, except in occasional institutional “Land Acknowledgement” statements. In this thesis, I focus on the work of environmental organizations and those focused on environmental and climate action. In a region where environmental and climate action claims to prioritize inclusion and consider diverse voices, I’ve noticed that groups in Maryland do not involve or engage with Tribal Peoples in the state.

description: Biofilms formed by pathogenic bacteria are complex communities adhering to surfaces, exhibiting increased resistance to disinfectants, thus leading to serious infections. Chemical disinfectants have long been utilized to eliminate pathogenic biofilms. Despite their potency and reliability, preliminary research suggests chemical disinfectants do not consistently achieve complete biofilm eradication. This PhD dissertation research focuses on investigating the factors governing biofilm formation and removal from food contact surfaces, such as identifying whether eithersurface roughness, kurtosis, or skewness promotes biofilm formation or if any of these factors provide additional protection against chemical disinfectants. Three research topics are included in this dissertation. The first topic is based on biofilm formation of pathogenic bacteria E. coli O157:H7, L. monocytogenes as a single species biofilm and in the presence of a non-pathogenic promoter bacterium R. insidiosa in a Centers for Disease Control and Prevention (CDC) bioreactor. Materials commonly used for food processing such as SS 316L, PTFE, EPDM, and Polycarbonate are used to grow biofilms at different shear stresses. The results from this study indicate that when E. coli O157:H7 biofilms are formed at low shear stress of 0.368 N/m2, the development is significantly heightened on surfaces with high kurtosis. This study underlines the importance of commonly sidelined surface parameters such as kurtosis. Our second research topic focuses on biofilm removal ability using chlorine from SS 316L, PTFE, and EPDM at a concentration up to 500 ppm for an exposure of 1 and 4 minutes at a flow of 1.2 liters per minute. Post-chlorine treatment, we observed that lower bacterial populations from L. monocytogenes biofilms were present in multispecies environment on PTFE material (high surface roughness), compared to SS 316L (low surface roughness) when these biofilms were grown at high shear stress of 2.462 N/m2. The third topic of this dissertation focuses on the biofilm removal using a more environmentally friendly chemical disinfectant Peroxyacetic acid to remove biofilms. When E. coli O157:H7 biofilms were formed in a multispecies environment at high shear stress and treated with peroxyacetic acid, removing biofilms from EPDM was found to be more challenging.

Two Stage Class Two Tensegrity Structure

description: Tensegrity structures are widely recognized for their advantages across diverse fields such as robotics, structural engineering, and aesthetics. This thesis endeavors to design and construct a novel two-stage class-two metal tensegrity structure featuring three compressive elements or bars, with an outline of the design improvements to the previous prototype and assembly process. Following assembly, the structure underwent various testing using the Polytec Laser Vibrometer to assess parameters including nodal coordinates and tension. Subsequently, the findings obtained were utilized as inputs for conducting the nodal analysis using MATLAB. This analysis aimed to determine the structure's mode shapes and corresponding natural frequencies within a constrained framework using two different form finding methods. With its inherent structural stability and symmetry, the assembled tensegrity structure serves as a valuable platform for further exploration and study of tensegrity parameters.
