Rapid Selection Of Moving Wagons In The Sequence Of Video Frames Based On The Method Of Calculating The Optical Flow, Bahodir Muminov Prof.

Bulletin of TUIT: Management and Communication Technologies

With the advent of digital video cameras, it has become possible to process measurement data using a computer, which has led to a wide range of new tasks in digital signal processing. Examples of such tasks are perimeter observation and detection of a moving object, recognition of a moving object, and identification of an object. Research and development of algorithms for processing video data, as a rule, requires a time-consuming computational experiment on model and real data of a large volume. Therefore, it is important to correctly organize the computational process when modifying and testing algorithms.

Using Liminality To Understand How Identity And Temporary Status Influence Interns’ Vulnerability, Michael A. Odio, Christopher M. Mcleod

Experiential Learning & Teaching in Higher Education

Viewing internships as a transitionary stage (i.e., a liminal space) where interns are shedding their student identity and developing their professional identity provides a useful lens for understanding the experiences of interns and holds implications for social and economic justice. As interns adapt to the temporary and transitionary space of the internship they experience powerlessness, ambiguity, and, in many cases exploitation, sexual harassment, and abuse. The stress and precarity of this status are compounded for interns from marginalized or underrepresented groups that must also conform to the (typically white male and middle class) hegemony of the workplace, all of which …

Promoting Educational Equity: Embedding Transformative Social And Emotional Learning In Experiential Learning, Christine P. Li-Grining, Amanda Roy, Marbella Uriostegui, Maria Radulescu, Zahra Naqi, Amanda Boyer

Experiential Learning & Teaching in Higher Education

Although college enrollment rates among Black and Latinx students have risen, inequities in graduation rates across racial and ethnic groups persist. Guided by the integration of strength-based frameworks, the proposed manuscript will discuss how experiential learning and teaching may serve a dual purpose: helping students enact social change while simultaneously reaching their education goals. The proposed manuscript will integrate the culturally engaging campus environments model with the transformative social-emotional learning (T-SEL) framework. Also, drawing from the existing literature, the proposed manuscript will describe a range of experiential learning activities and how they may involve T-SEL. We then conclude with implications …

Building An Ecosystem Of Diversity Talent Development Through Experiential Learning, Marianna Savoca, Kimberly Dixon, Urszula Zalewski

Experiential Learning & Teaching in Higher Education

Access to professionals and insider knowledge of industry is often limited to students from privileged families, yet most academic support programs focus solely on persistence to graduation. Career readiness through experiential learning has not yet reached strategic importance for these programs. One public research university in the northeast which enrolls a highly diverse student body has created a portfolio of programs to connect underrepresented students with industry partners for career development, experiential learning, mentoring, and networking.

Justice Isn’T One-Size-Fits-All: Working Toward Justice In Service-Learning Courses, Chelsea Lauder, Becca Berkey

Experiential Learning & Teaching in Higher Education

Service-Learning is a form of experiential education and a teaching tool that can both enhance student learning outcomes and contribute to community goals. When this type of learning intersects with social justice education, or liberatory education, different types of student outcomes may arise; specifically, those contributing to the development of social and critical consciousness. In this thought piece on praxis, we conduct a content analysis of multiple first- and second- year service-learning courses to determine if there is an observable difference in the development of student social consciousness and commitment as it pertains to the extent to which justice is …

The second issue to be addressed are the impacts of the 2012 drought on agriculture in Nebraska and the region. The drought of 2012 indicates that future droughts in the 21^st century in the region can be a dominant influence on …

Nodal Modulator Is Required To Sustain Endoplasmic Reticulum Morphology¬, Catherine Amaya

Yale Graduate School of Arts and Sciences Dissertations

Nodal modulator (NOMO) is a widely conserved type I transmembrane protein of unknown function, with three nearly identical orthologs specified in the human genome. We identified NOMO1 in a proteomics approach aimed at the identification of proteins that support the structural integrity of the endoplasmic reticulum (ER). We have investigated the role of NOMO1 in relation to ER morphology. Overexpression of NOMO1 imposes sheet morphology on the ER. Extending NOMO1 correlatively increases the ER intermembrane distance, demonstrating the ability to regulate the ER lumen distance. Depletion of NOMO1 and its orthologs causes a collapse of ER morphology concomitant with the …

The Role Of Post-Translational Modifications In The Fate Of Nascent Tail-Anchored Membrane Proteins, Jacob Andrew Culver

Yale Graduate School of Arts and Sciences Dissertations

Membrane proteins contain hydrophobic transmembrane domains (TMDs) which reside in the nonpolar section of cellular membranes. The synthesis of the majority of membrane proteins in eukaryotes is routed through the co-translational insertion pathway. As they are translating nascent membrane proteins, ribosomes are delivered to the endoplasmic reticulum (ER) where the new membrane protein is co-translationally inserted directly into the membrane as it emerges from the ribosome exit tunnel. Thus, newly translated hydrophobic TMDs are never released into the aqueous cytosol. However, exceptions to the co-translational insertion route exist. Certain membrane proteins are released into the cytosol and must be captured …

Nitrogen Cycle Chemistry With Metal-Pincer Complexes Relevant To Electrochemical Nitrogen Fixation, Gannon Patrick Connor

Yale Graduate School of Arts and Sciences Dissertations

The large-scale industrial fixation of N2 to NH3 through the Haber-Bosch process has cemented itself as the primary means to provide N for fertilizer and commodity chemicals globally. However, our dependence on this process is unsustainable in the long term due to its reliance on fossil fuels to generate H2 and to provide the substantial energy input for the reaction, paired with high infrastructure requirements that necessitate centralized synthesis plants and sophisticated transportation networks. As an alternative, electrochemical fixation of N2, coupling water oxidation to provide proton (H+) and electron (e–) equivalents with the N2 reduction reaction (NRR) to achieve …

Determination And Application Of Hydrogen Transfer Thermochemistry: Studies Of Molecules, Nanoparticles, And Metallic Electrodes, Rishi Agarwal

Yale Graduate School of Arts and Sciences Dissertations

From the surface of a platinized electrode in a hydrogen fuel cell to the oxygen-evolving complex in photosystem II, the binding and transfer of hydrogen is central to many important chemical transformations in our world. The core thermochemical and kinetic concepts which connect these proton-coupled electron transfers across a continuum of compound sizes, including small molecules, nanoparticles, and bulk materials, are explored. In Chapter 1, an introduction to the thermochemical basis for this thesis is presented, along with the underlying connections it enables for studying hydrogen transfer across thermochemical and electrochemical reactions, as well as gas and solution phase reactivity.Methods …

Three-Wave Mixing In Superconducting Circuits: Stabilizing Cats With Snails, Nicholas Frattini

Yale Graduate School of Arts and Sciences Dissertations

Three-wave mixing, by which a photon splits into two correlated photons and vice versa, is a powerful quantum process with many applications in fundamental quantum mechanics experiments and quantum information processing. However, in superconducting circuits, the predominant form of nonlinearity provided by a Josephson junction is only of even order, and thus symmetry forbids three-wave mixing. This Kerr nonlinearity is useful in its own right for engineering quantum operations, but it is accompanied by unavoidable frequency shifts that become especially problematic as the number of interacting electromagnetic modes, and therefore frequency crowding, increases. How then can we endow superconducting devices …

Computational Principles Of Multiple-Task Learning In Humans And Artificial Neural Networks, Daniel Benjamin Ehrlich

Yale Graduate School of Arts and Sciences Dissertations

While humans can learn to perform many specific and highly specialized behaviors,perhaps what is most unique about human cognitive capabilities is their capacity to generalize, to share information across contexts and adapt to the myriad problems that can arise in complex environments. While it is possible to imagine agents who learn to deal with each challenge they experience separately, humans instead integrate new situations into the framework of the tasks they have experienced in their life, allowing them to reuse insight and strategies across them. Yet the precise forms of shared representations across tasks, as well as computational principles for …

Mapping A Functional Cancer Genome Atlas, Ryan Dz-Wei Chow

Yale Graduate School of Arts and Sciences Dissertations

Over the past decade, tremendous resources have been devoted to sequencing the genomes of patient cancers. But while the molecular portraits of cancer are now in higher resolution than ever before, it has remained challenging to derive clinically actionable insights from these data. A central issue is that tumor genome sequencing often can only tell us what mutations are present, not which ones are functionally important. Towards this end, I sought to build an improved toolkit for functional cancer genomics, with the overarching goal of creating experimental platforms that are practical, scalable, and flexible. In collaboration with several colleagues, I …

Expanding The Reliable Paleomagnetic Constraints On Configurations Of Pre-Pangean Supercontinents, Zheng Gong

Yale Graduate School of Arts and Sciences Dissertations

Supercontinents embody perhaps the longest cyclic process on our planet, profoundly influencing the evolution of Earth’s biosphere, geosphere, and atmosphere on timescales of hundred-million years or more. Yet, the configurations of pre-Pangean supercontinents, Rodinia, Nuna, and/or Kenorland, as well as their transition processes remain the subjects of debate, hampering the understanding of the interactions between the global tectonics and Earth’s evolution in deep time. Compared to other approaches, paleomagnetism is the only quantitative method to reconstruct pre-Pangean supercontinents in an absolute paleogeographic framework. However, a recent summary of global paleomagnetic data of Precambrian age reveals two problems. First is that …

Tax The Rich: Teachers' Long Campaign To Fund Public Schools, Kelly Goodman

Yale Graduate School of Arts and Sciences Dissertations

Why did teachers’ long campaign to fund schools with progressive income taxes on the rich fall short? Labor-liberals hoped to equalize opportunity for students by shifting school taxes from local communities like Detroit and Los Angeles to the states. Businessmen and conservatives instead centralized cuts by changing how budget decisions are made, imposing constitutional limits to slow the growth rate of state government. Tax limits are distinct from tax cuts. Tax the Rich builds on the established literature about the grassroots politics of education, and moves in new directions by centering the agency of organized interests—teachers unions, business associations, and …

Rise Of The Modern Mediatrix: The Feminization Of Media And Mediating Labor, 1865-1945, Leana Hirschfeld-Kroen

Yale Graduate School of Arts and Sciences Dissertations

This dissertation uncovers a vast archive of fictional female telegraph, telephone, and typewriter girls, combining rigorous historical research with feminist, psychoanalytic readings of mass cultural texts to show how the global gendering of low-level communication work shaped modern media. It begins in the United States, where women first performed this work, and explores three further national contexts (France, Germany, and Britain) where female operators and typists circulated as media icons of techno-social connection in an increasingly atomized age. The title “modern mediatrix” describes the essential mediating role white-collar woman workers have played in modern media infrastructure, from switchboard to editing …

Advancing The Underactuated Grasping Capabilities Of Single Actuator Prosthetic Hands, Michael Thomas Leddy

Yale Graduate School of Arts and Sciences Dissertations

The last decade has seen significant advancements in upper limb prosthetics, specifically in the myoelectric control and powered prosthetic hand fields, leading to more active and social lifestyles for the upper limb amputee community. Notwithstanding the improvements in complexity and control of myoelectric prosthetic hands, grasping still remains one of the greatest challenges in robotics. Upper-limb amputees continue to prefer more antiquated body-powered or powered hook terminal devices that are favored for their control simplicity, lightweight and low cost; however, these devices are nominally unsightly and lack in grasp variety. The varying drawbacks of both complex myoelectric and simple body-powered …
