In this study, a simple TACE robotic system of 4-degree-of-freedom is proposed to get higher accuracy and stability of the surgery operation and reduce X-ray exposure time of the surgeons. The master-slave control strategy is adopted in the robotic system and a customized sigmoid function is designed to optimize the joystick control of the master-slave robotic control system. A force-sensing module is developed to sense the resistance of the guide wire in linear delivery motion and an auxiliary bending feedback method based on constraint …

Uncharted Communities Of Crowdsourced Plagiarism, Zachary P. Dixon, Kelly A. Whealan-George

Publications

This paper reports on a study of crowd-sourcing ‘study aid’ web platforms. Students are sharing completed academic coursework through a growing network of ‘study aid’ web platforms like CourseHero.com. These websites facilitate the crowd-sourced exchange of coursework, and effectively support plagiarism. However, virtually no data exists concerning the scope or extent of coursework being shared through these platforms. This paper reports on two experiments to monitor the frequency of coursework from a sample university uploaded onto CourseHero.com. Ultimately, both experiments failed to produce a clear or meaningful measurement of coursework upload frequency. The apparently widespread use of these crowdsourcing ‘study …

Zero-Bias Deep Learning For Accurate Identification Of Internet Of Things (Iot) Devices, Yongxin Liu, Houbing Song, Thomas Yang, Jian Wang, Jianqiang Li, Shuteng Niu, Zhong Ming

Publications

The Internet of Things (IoT) provides applications and services that would otherwise not be possible. However, the open nature of IoT makes it vulnerable to cybersecurity threats. Especially, identity spoofing attacks, where an adversary passively listens to the existing radio communications and then mimic the identity of legitimate devices to conduct malicious activities. Existing solutions employ cryptographic signatures to verify the trustworthiness of received information. In prevalent IoT, secret keys for cryptography can potentially be disclosed and disable the verification mechanism. Noncryptographic device verification is needed to ensure trustworthy IoT. In this article, we propose an enhanced deep learning framework …

Experimental Study Of Breathers And Rogue Waves Generated By Random Waves Over Non-Uniform Bathymetry, A. Ludu, A. Wang, Z. Zong, L. Zou, Y. Pei

Publications

We present experimental evidence of formation and persistence of localized waves, breathers, and solitons, occurring in a random sea state and uniformly traveling over non-uniform bathymetry. Recent studies suggest connections between breather dynamics and irregular sea states and between extreme wave formation and breathers, random sea states, or non-uniform bathymetry individually. In this paper, we investigate the joint connection between these phenomena, and we found that breathers and deep-water solitons can persist in more complex environments. Three different sets of significant heights have been generated within a Joint North Sea Wave Observation Project wave spectrum, and the wave heights were …

Covid-19, 5g Conspiracies And Infrastructural Futures, James Meese, Jordan Frith, Rowan Wilken

Perspectives On Undergraduate Research Mentorship: A Comparative Analysis Between Online And Traditional Faculty, Emily K. Faulconer, Zachary Dixon, John Griffith, Laura Faulconer

Publications

With an increase in distance faculty, it is important to understand how faculty perceptions of undergraduate research mentorship differ between distance and traditional faculty. Perceptions were examined in a medium sized, not-for-profit university with both residential and distance faculty. Residential faculty were more likely to mentor or were very interested in undergraduate research, but overall interest in mentorship was similar across campuses. Faculty status or career experience was not correlated to interest or engagement in research mentorship. Traditional faculty were more likely to report time commitment as a significant barrier than distance faculty. Other barriers and benefits were aligned between …

Reuse of the collected data will support efforts to improve the understanding of the physical …

Unlocking The Final Code To Managing Financial Risk In The Airline Industry, Sunder Raghavan, Alfonso Canella Higuera, Maneesh Sharma, Ron Mau

Publications

This paper reports our findings on the effectiveness of revenue hedging using the newly proposed price indices by Skytra. In the example analyzed we find that when hedged, if United Airlines’ transatlantic ticket price yields fell as much as 98%, its revenues would have only fallen 8%.

Firstly, we explore revenue hedging and the evolution of financial risk management practices for the aviation industry. Until now, the industry has been confined to hedging risks posed by its major cost drivers, including fuel, foreign exchange and interest rates. However, even the most significant driver of these costs (fuel) makes up only …

The proliferation of small multi-rotor UAVs in commercial, recreational, and surveillance spheres has garnered significant interest in the noise produced by these vehicles. The current research aims to study the relationship between the aerodynamic performance and acoustic characteristics of small-scale UAV propellers. Three commercially available propellers for the DJI Phantom 2/3 UAV were selected for preliminary development and validation of an aeroacoustic experimental test setup and associated data reduction methods. Propeller thrust, torque, and power measurements were recorded at static conditions. Upon successful validation of the test bench, acoustic measurements were taken at the propeller disk’s upstream and in-plane locations. …

Performance Testing Of Aero-Naut Camfolding Propellers, Or D. Dantsker, Robert W. Deters, Marco Caccamo, Michael S. Selig

Publications

The increase in popularity of unmanned aerial vehicles (UAVs) has been driven by their use in civilian, education, government, and military applications. However, limited on-board energy storage significantly limits flight time and ultimately usability. The propulsion system plays a critical part in the overall energy consumption of the UAV; therefore, it is necessary to determine the most optimal combination of possible propulsion system components for a given mission profile, i.e. propellers, motors, and electronic speed controllers (ESC). Hundreds of options are available for the different components with little performance specifications available for most of them. By examining a variety of …

We study the 2N-dimensional canonical systems and discuss some properties of its fundamental solution. We then discuss the Floquet theory of periodic canonical systems and observe the asymptotic behavior of its solution. Some important physical applications of the systems are also discussed: linear stability of periodic Hamiltonian systems, position-dependent effective mass, pseudo-periodic nonlinear water waves, and Dirac systems.

Use Of Dual Rna-Seq For Systems Biology Analysis Of Zea Mays And Aspergillus Flavus Interaction, Bryan Musungu, Deepak Bhatnagar, Sylvie Quiniou, Robert L Brown, Gary A Payne, Greg O'Brian, Ahmad M. Fakhoury, Matt Geisler

Publications

The interaction between Aspergillus flavus and Zea mays is complex, and the identification of plant genes and pathways conferring resistance to the fungus has been challenging. Therefore, the authors undertook a systems biology approach involving dual RNA-seq to determine the simultaneous response from the host and the pathogen. What was dramatically highlighted in the analysis is the uniformity in the development patterns of gene expression of the host and the pathogen during infection. This led to the development of a “stage of infection index” that was subsequently used to categorize the samples before down-stream system biology analysis. Additionally, we were …

Data Literacies And Social Justice: Exploring Critical Data Literacies Through Sociocultural Perspectives, Golnaz Arastoopour Irgens, Simon Knight, Alyssa Friend Wise, Thomas M. Philip, Maria C. Olivares, Sarah Van Wart, Sepehr Vakil, Jessica Marshall, Tapan Parikh, M. Lisette Lopez, Michelle Hoda Wilkerson, Kris Gutierrez, Shiyan Jiang, Jennifer B. Kahn

Publications

The ability to interpret, evaluate, and make data-based decisions is critical in the age of big data. Normative scripts around the use of data position them as a privileged epistemic form conferring authority through objectivity that can serve as a lever for effecting change. However, humans and materials shape how data are created and used which can reinscribe existing power relations in society at large (Van Wart, Lanouette & Parikh, 2020). Thus, research is needed on how learners can be supported to engage in critical data literacies through sociocultural perspectives. As a field intimately concerned with data-based reasoning, social justice, …

Students’ Epistemic Connections Between Science Inquiry Practices And Disciplinary Ideas In A Computational Science Unit, Sugat Dabholkar, Golnaz Arastoopour Irgens, Michael Horn, Uri Wilensky

Publications

Teaching science inquiry practices, especially the more contemporary ones, such as computational thinking practices, requires designing newer learning environments and appropriate pedagogical scaffolds. Using such learning environments, when students construct knowledge about disciplinary ideas using inquiry practices, it is important that they make connections between the two. We call such connections epistemic connections, which are about constructing knowledge using science inquiry practices. In this paper, we discuss the design of a computational thinking integrated biology unit as an Emergent Systems Microworlds (ESM) based curriculum. Using Epistemic Network Analysis, we investigate how the design of unit support students’ learning through making …
