The Most Challenging Part? Selecting A Dissertation Topic For Aviation Research, Scott R. Winter, David S. Cross

Publications

In the U.S., more than 50%of students who complete the coursework for a Ph.D. cannot complete the dissertation. Students fail to complete their dissertation, hence their Ph.D., for several reasons, but most of them are within their control. Many students start the dissertation process without a clear vision of a dissertation's actual purpose and what makes a successful dissertation. Specific technical areas, such as aviation, can be incredibly challenging to navigate during the Ph.D. process. The purpose of this study was twofold. First, we wanted to write a paper that describes several techniques to help Ph.D. students set realistic foundations …

Assessing The Severity Of Health States Based On Social Media Posts, Shweta Yadav, Joy Prakash Sain, Amit P. Sheth, Asif Ekbal, Sriparna Saha, Pushpak Bhattacharyya

Publications

The unprecedented growth of Internet users has resulted in an abundance of unstructured information on social media including health forums, where patients request healthrelated information or opinions from other users. Previous studies have shown that online peer support has limited effectiveness without expert intervention. Therefore, a system capable of assessing the severity of health state from the patients’ social media posts can help health professionals (HP) in prioritizing the user’s post. In this study, we inspect the efficacy of different aspects of Natural Language Understanding (NLU) to identify the severity of the user’s health state in relation to two perspectives(tasks) …

Alone: A Dataset For Toxic Behavior Among Adolescents On Twitter, Thilini Wijesiriwardene, Hale Inan, Ugur Kursuncu, Manas Gaur, Valerie L. Shalin, Krishnaprasad Thirunarayan, Amit P. Sheth, I. Budak Arpinar

Publications

The convenience of social media has also enabled its misuse, potentially resulting in toxic behavior. Nearly 66% of internet users have observed online harassment, and 41% claim personal experience, with 18% facing severe forms of online harassment. This toxic communication has a significant impact on the well-being of young individuals, affecting mental health and, in some cases, resulting in suicide. These communications exhibit complex linguistic and contextual characteristics, making recognition of such narratives challenging. In this paper, we provide a multimodal dataset of toxic social media interactions between confirmed high school students, called ALONE (AdoLescents ON twittEr), along with descriptive …

Airport Ceos And The Decentralized System Of Airports: A Case Study, Marjan Mazza

Publications

The job of the airport CEO is complex with responsibility for the security and safety of a large and dynamic facility and, yet the FAA does not have regulatory qualification and performance standards for the position. The purpose of this qualitative multi-case study was to explore the primary attributes that could be the leading indicators in the event national standards for the hiring of airport CEOs are pursued at major commercial airports. The guiding conceptual framework of the study was to combine competency with the concept of training and development. Airport CEOs from six airport facilities were interviewed, and an …

Second Amendment Background Principles And Heller's Sensitive Places, Adam B. Sopko

Publications

Judges and commentators have widely acknowledged that history enjoys a privileged status in Second Amendment cases, but its precise role is undertheorized and rarely controls case outcomes. In particular, courts have been unable to decide "sensitive places" cases—challenges to location-based gun laws—in a manner that adheres to Supreme Court precedent because existing Second Amendment doctrine lacks a test for sensitive places cases that uses history and tradition in a principled way. This Article proposes a solution to address that problem.

An untapped source of guidance is the Court’s takings jurisprudence. Interpreting their respective constitutional provisions, Justice Scalia observed that both …

Not Everything Is About Investors: The Case For Mandatory Stakeholder Disclosure, Ann Lipton

Publications

Corporations are required to disclose specific types of information to the public, but only the federal securities laws impose generalized disclosure obligations that produce a holistic overview of corporate operations. While these disclosures are intended to benefit investors, they are accessible to anyone, and thus have long been relied upon by regulators, competitors, employees, and local communities to provide a working portrait of the country’s economic life.

Today, that system is breaking down. Congress and the SEC have made it easier for companies to raise capital without triggering securities reporting obligations, allowing modern businesses to grow to enormous proportions while …

Monetizing Infringement, Kristelia García

Publications

The deterrence of copyright infringement and the evils of piracy have long been an axiomatic focus of both legislators and scholars. The conventional view is that infringement must be curbed and/or punished in order for copyright to fulfill its purported goals of incentivizing creation and ensuring access to works. This Essay proves this view false by demonstrating that some rightsholders don’t merely tolerate, but actually encourage infringement, both explicitly and implicitly, in a variety of different situations and for one common reason: they benefit from it. Rightsholders’ ability to monetize infringement destabilizes long-held but problematic assumptions about both rightsholder preferences, …

Taming America's Sugar Rush: A Traffic-Light Label Approach, Alexia Brunet Marks

Publications

Excess added sugar negatively impacts health and can lead to a litany of problems, such as diet-related chronic diseases, e.g., diabetes, cancer, heart disease, and obesity, costing Americans millions in rising medical bills each year. Even more, new studies reveal that individuals with these underlying chronic diseases are at a higher risk of complications from COVID-19 and other viruses compared to those who are deemed healthy. And yet added sugars are difficult to avoid because unlike naturally occurring sugars found in fruits, vegetables, and milk, these sweeteners are added during food processing and preparation.

The problem is that while consumers …

Remutualization, Erik F. Gerding

Publications

Policymakers need to rediscover the organizational form of business entity as a tool of financial regulation. Recent and classic scholarship has produced evidence that financial institutions organized as alternative entity forms – including investment bank partnerships and banks and insurance companies organized as mutual or cooperatives – tend to take less risk, exploit customers/consumer less, or commit less misconduct compared to counterparts organized as investor-owned corporations. This article builds off the work of Hill and Painter on investment banks organized as partnerships, Hansmann on the history and economics of banks and insurance companies organized as mutuals and cooperatives, and other …

Ueb Parallel: Distributed Snow Accumulation And Melt Modeling Using Parallel Computing, Tseganeh Z. Gichamo, David G. Tarboton

Publications

The Utah Energy Balance (UEB) model supports gridded simulation of snow processes over a watershed. To enhance computational efficiency, we developed two parallel versions of the model, one using the Message Passing Interface (MPI) and the other using NVIDIA's CUDA code on Graphics Processing Unit (GPU). Evaluation of the speed-up and efficiency of the MPI version shows that the effect of input/output (IO) operations on the parallel model performance increases as the number of processor cores increases. As a result, although the computation kernel scales well with the number of cores, the efficiency of the parallel code as a whole …

Student Nutrition Access Center: Impact Analysis 2019, Amanda M. Hagman, Hayden Hoopes, Nelda Ault-Dyslin

Publications

Introduction: Access to nutritional food items is crucial to student well-being, which in turn is crucial to student success. Student success emerges from “the amount of physical and psychological energy that the student devotes to the academic experience” (Astin, 1984). Campus nutrition programs help students eliminate food security issues so that they can devote more energy to the academic experience. However, creating efficient and convenient nutrition programs requires that administrators understand the complexities of their implementation, their effect on specific student segments, and their effect on decisions to either persist at or leave an institution. This report explores the impact …

Determination Of Global Mean Eddy Diffusive Transport In The Mesosphere And Lower Thermosphere From Atomic Oxygen And Carbon Dioxide Climatologies, G. R. Swenson, C. C. J. H. Salinas, F. Vargas, Y. Zhu, M. Kaufmann, M. Jones Jr., A. Liu, Et Al.

Publications

Quantifying the eddy diffusion coefficient profile in the mesosphere and lower thermosphere (MLT) is critical to the constituent density distributions in the upper mesosphere and thermosphere. Previous work by Swenson et al. (2018, https://doi.org/10.1016/j.jastp.2018.05.014) estimated the global mean eddy diffusion (kzz) values in the upper mesosphere using atomic oxygen (O), derived from Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) hydroxyl (OH). In this study, vertical eddy diffusive transport velocities of O were determined from continuity of mass in the mesopause region (80–97 km), primarily via the HOx chemistry. Global average constituent climatology from previously deduced SABER ozone (O3) …

Thermodynamic Model Of Co2 Deposition In Cold Climates, Sandra K. S. Boetcher, Ted Von Hippel, Matthew J. Traum

Publications

A thermodynamic model, borrowing ideas from psychrometric principles, of a cryogenic direct-air CO2-capture system utilizing a precooler is used to estimate the optimal CO2 removal fraction to minimize energy input per tonne of CO2. Energy costs to operate the system scale almost linearly with the temperature drop between the ingested air and the cryogenic desublimation temperature of CO2, driving siting to the coldest accessible locations. System performance in three Arctic/Antarctic regions where the proposed system can potentially be located is analyzed. Colder ambient temperatures provide colder system input air temperature yielding lower CO2 removal energy requirements. A case is also …

An Algorithm For Coupling Multibranch In Vitro Experiment To Numerical Physiology Simulation For A Hybrid Cardiovascular Model, Ehsan Mirzaei, Masoud Farahmand, Ethan Kung

Publications

The hybrid cardiovascular modeling approach integrates an in vitro experiment with a computational lumped‐parameter simulation, enabling direct physical testing of medical devices in the context of closed‐loop physiology. The interface between the in vitro and computational domains is essential for properly capturing the dynamic interactions of the two. To this end, we developed an iterative algorithm capable of coupling an in vitro experiment containing multiple branches to a lumped‐parameter physiology simulation. This algorithm identifies the unique flow waveform solution for each branch of the experiment using an iterative Broyden's approach. For the purpose of algorithm testing, we first used mathematical …

Deepfuzzer: Accelerated Deep Greybox Fuzzing, Jie Liang, Yu Jiang, Mingzhe Wang, Houbing Song, Kim-Kwang Raymond Choo

Publications

Fuzzing is one of the most effective vulnerability detection techniques, widely used in practice. However, the performance of fuzzers may be limited by their inability to pass complicated checks, inappropriate mutation frequency, arbitrary mutation strategy, or the variability of the environment. In this paper, we present DeepFuzzer, an enhanced greybox fuzzer with qualified seed generation, balanced seed selection, and hybrid seed mutation. First, we use symbolic execution in a lightweight approach to generate qualified initial seeds which then guide the fuzzer through complex checks. Second, we apply a statistical seed selection algorithm to balance the mutation frequency between different seeds. …

A Survey Of Mathematical Models Of Human Performance Using Power And Energy, Vijay Sarthy Mysore Sreedhara, Gregory M. Mocko, Randolph E. Hutchison

Publications

The ability to predict the systematic decrease of power during physical exertion gives valuable insights into health, performance, and injury. This review surveys the research of power-based models of fatigue and recovery within the area of human performance. Upon a thorough review of available literature, it is observed that the two-parameter critical power model is most popular due to its simplicity. This two-parameter model is a hyperbolic relationship between power and time with critical power as the power-asymptote and the curvature constant denoted by W′. Critical power (CP) is a theoretical power output that can be sustained indefinitely by …

Fatigue Issues And Mitigation Strategies In Collegiate Aviation, Flavio A. C. Mendonca Ph.D., Julius Keller, Erik Levin, Aaron Teo

Publications

The reduction of fatigue-related accidents has been in the NTSB most wanted list since 2016 (NSTB, 2019).

Most research studies have focused on fatigue identification and management within the commercial and/or military aviation environments (Caldwell et al., 2009; Gawron, 2016; Sieberichs & Kluge, 2016).

However, collegiate aviation may be the most challenging in terms of fatigue mitigation. Flight instructors and students often have schedules which may increase the risks for fatigue.
