  • Scaffolding Your Instruction with Epistemology

    Dean, Kirsten; University Libraries at Virginia Tech (The University of Arizona, 2020-09)
    Slides from pre-recorded video (https://youtu.be/W1_6lMTVZ7M) and live virtual discussion session (Sept. 16, 2020).
  • Extensions for Everyone: Syllabus Policies that Center Accessibility

    Wong, Melissa; University of Illinois at Urbana-Champaign (The University of Arizona, 2020-09-14)
    Instructors who embrace critical pedagogy work to create inclusive learning environments and dismantle barriers to education. Ironically, one such barrier can be the formal accommodations process that was created to ensure equitable access for student with disabilities (only a fraction of students with disabilities request needed accommodations). In order to better serve students with disabilities, many instructors have adopted Universal Design for Learning (UDL) and a proactive approach to accessible course design. Instructors implementing UDL often focus on the accessibility of course materials and using varied and inclusive pedagogical strategies. However, instructors may overlook the central role course policies play in accessibility. In fact, many common accommodations are a direct response to instructor policies. For example, instructors may be asked to grant an extension for a due date if a student experiences exacerbation of a chronic illness; however, this accommodation only exists as a standard accommodation because of instructors’ often inflexible policies around attendance and deadlines. In this talk, I identify course policies that create barriers for students with disabilities and show how instructors can adopt more flexible course policies that support inclusion and student success while decreasing the need for formal accommodations.

  • The library is not a restaurant: Reference appointments and neoliberal language

    Gardner, Carolyn Caffrey; Clarke, Maggie; California State University, Dominguez Hills (The University of Arizona, 2020-09-04)
    This presentation will detail research on “no-show” student research appointments with an eye towards how libraries can mitigate student perceptions of appointments as commercial transactions which have been reinforced by problematic language borrowed from other sectors (hospitality, medical). We will share survey results from a range of higher education institutions regarding their current attitudes and practices towards no-show appointments. We will present strategies we’ve used to encourage appointment attendance by fostering a sense of shared community of learners rather than using shame, financial penalty, or other punitive action to decrease no-shows. Finally, we’ll hear from students on their perceptions of taking up space in research appointments and analyze how research appointment practices can reward students who already have privilege. Participants will critically reflect on their own experiences and practices with research appointments through guided reflection and small group discussion in order to empower students.
  • Reimagining Peer Review

    Ford, Emily; Portland State University (The University of Arizona, 2020-09)
    As you may recall, the 2020 Critical Library and Pedagogy Symposium instituted an open peer review process—not masking submitters’ names and other identifying information—to review proposed sessions. This decision came after the committee noted a lack of diversity in accepted sessions using a closed review process. Using open peer review allowed the committee to balance accepted proposals and offer a diverse range of views and experiences among presenters. This hour-long facilitated discussion will examine bias and power structures inherent in peer review. It will be an interactive session that allows participants to critically examine their views and previous experiences with peer review, and begin to reimagine it. What can opening peer review do to create more equitable scholarly spaces? What problems does opening peer review improve, and what new challenges does it present? Note that this session will be interactive, and will use the Zoom breakout room feature as well as Google Docs for collaboration.
  • Beyond Self-Care and Standardization: Creating a Sustainable Teaching Practice through Engaged Pedagogy

    Arellano Douglas, Veronica; Deal, Emily; Hernandez, Carolina; University of Houston (The University of Arizona, 2020-09-16)
    Conversations around sustainable teaching practices either focus on self-care, placing responsibility for well-being on librarians; or program efficiency, which creates work environments that create business-like models for standardization of teaching programs. This framing of sustainability is reactive and harmful -- we are working within existing power structures and dynamics rather than imagining ways to share power and create space for engaged pedagogy. bell hooks introduces the concept of engaged pedagogy as a model of education that “does not seek to simply empower students… [but] will also be a place where teachers grow and are empowered by the [learning] process” (p. 21). It’s a feminist expansion of critical pedagogy that takes into account the personhood of the teacher as well as the student, creating a co-learning environment rooted in mutual respect where intellectual and personal development can flourish. This discussion session moves beyond typical sustainability conversations to develop ideas for positive change in library teaching programs with the goal of creating generative, healthy work practices
  • The Good, The Bad, and The Non-Circular Signals

    Bose, Tamal; Tsang, Stephanie D.; Samuel, Al; Univ Arizona, Dept Electrical and Computer Engineering (International Foundation for Telemetering, 2019-10)
    Second-order (SO) non-circularity is a statistical property that is used to classify signals. Signals with SO non-circularity are extensively used in communication and radar systems. The SO non-circularity property is generally useful in the application of array processing techniques for extending antenna apertures. Exploiting this non-circularity property for a multi-faceted set of communication-type and radar-type signals is the objective of this study. For a given type of signal, the circularity quotient and its properties are tested and evaluated in terms of parameters such as the modulus of its phase, complex covariance, pseudo-variance, the angle orientation of the ellipse, its eccentricity, and other relevant properties are calculated. A geometrical interpretation for the circularity quotient and the correlation coeficient is used to derive the bounds for circularity.
  • DOPPLER POWER SPECTRA FROM VEHICLE-TO-EVERYTHING PROPAGATION EXPERIMENTS

    Rice, Michael; Harrison, Willie K.; Norman, Kalin; Jensen, Benjamin; Brigham Young University, Dept Electrical and Computer Engineering (International Foundation for Telemetering, 2019-10)
    This paper presents the results of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) propagation experiments. The experimental results are summarized by Doppler power spectra. Our measurements indicate the need for a dynamic system that can handle the variable channels experienced in vehicle-to-everything communications.
  • APSK SYMBOL TIMING AND CARRIER PHASE SYNCHRONIZATION ON AN FPGA IN A C-BAND TELEMETRY RECEIVER

    Perrins, Erik; Baxter, Jason; Univ Kansas, Dept Electrical Engineering and Computer Science (International Foundation for Telemetering, 2019-10)
    This paper presents the implementation of a standard PLL-based timing and phase synchronization system on hardware usingan FPGA. The synchronization system is shown to successfully recover a 16-APSK signal despite off sets in phase and frequency between the transmitter and receiver local oscillators. Furthermore, it is shown that system performance, in terms of symbol times required to achieve lock, is comparable to double-precision floating point simulations despite using fixed point numbers with as few as 5 fractional bits for most computations.
  • HIGH-PERFORMANCE EXTENSIBLE SOQPSK (E-SOQPSK) MODULATION WAVEFORMS FOR AERONAUTICAL MOBILE TELEMETRY COMMUNICATIONS

    Lu, Cheng Y.; Argula, Rajeev; Sasvari, Gyorgy; Cook, Paul; Teletronics a Curtiss-Wright Company (International Foundation for Telemetering, 2019-10)
    To utilize the resilience to multipath and rapidly varying Doppler shifts offered by a multicarrier (MC) Orthogonal Frequency Division Multiplexed (OFDM) modulation waveform, and the high transmitter power efficiency offered by a single carrier (SC) Shaped Offset Quadrature Phase Shift Keying (SOQPSK) modulation waveform, we propose a novel Extensible Shaped Offset Quadrature Phase Shift Keying (E-SOQPSK) modulation waveform. E-SOQPSK is an OFDM structured single carrier modulation waveform, configurable to include OQPSK, SOQPSK, or mQAM. Preliminary laboratory results confirmed its low Peak-to-Average Power ratio (PAPR) and high spectrum efficiency. Preliminary simulations demonstrated multipath resilience of ESOQPSK waveform by utilizing OFDM structure based Frequency-Domain equalization at receiver.
  • JFLUTTER REAL TIME FLUTTER ANALYSIS IN FLIGHT TEST

    Rubio, Pedro; Coll, Francisca; AIRBUS DEFENCE & SPACE Flight Test (International Foundation for Telemetering, 2019-10)
    During the development of an aircraft it is mandatory to demonstrate that the aircraft is free from flutter within its operational flight envelope. This piece showcases JFlutter, a flutter analysis tool developed within Airbus Defence & Space Flight Test Analysis Tools. JFlutter allows the analysis of this phenomenon in real time monitoring and post flight mode. Using the FxS dataserver as data provider, a reliable data gathering mechanism has been used for this critical tool. As flutter means aero elastic instability, potentially dangerous, flight safety becomes a main requirement. For safety reasons and in order to reduce overall test program duration it is necessary to check predicted frequencies and damping in real time / monitoring.
  • Latest Development Status on the Commercial derivative aircraft Based Instrumentation Telemetry System (CBITS) Program

    Roudebush, J. Kyle; Hernandez, Jose; Kujiraoka, Scott; NAVAIR-Point Mugu; GBL Systems (International Foundation for Telemetering, 2019-10)
    The Commercial derivative aircraft Based Instrumentation Telemetry System (CBITS) project will provide an advanced airborne telemetry system and capability to support the test and evaluation (T&E) of current and future military weapons and defensive systems. In conjunction with the Range Support Aircraft (RSA) contracts, the CBITS project will provide an autonomous airborne T&E asset capable of supporting Major Range and Test Facility Base (MRTFB) government ranges and open-ocean testing worldwide. The project will develop an improved S-Band airborne telemetry (TM) capability and a new L- and C-Band telemetry capability as a result of frequency spectrum selloff issues. These improved telemetry capabilities, along with the existing airborne Flight Termination System/Command Destruct (FTS/CD) capability, existing radar for Range Surveillance (RS) and Range Clearance (RC), and range unique augmenting communication systems will be integrated into a Gulfstream G550 Airborne Early Warning (AEW) RSA which will be replacing the current NP-3D Remote Area Safety Aircraft (RASA). This paper will discuss the latest developmental status of the CBITS project.
  • APPLICATIONS OF AUTONOMOUS NAVIGATION IN NEXT-GENERATION MARS ROVERS

    Kosbar, Kurt; Dlouhy, Sarah; Arneson, Ethan; Missouri University of Science and Technology (International Foundation for Telemetering, 2019-10)
    This paper describes a module used to provide autonomous navigation and obstacle avoidance to a teleoperated prototype Mars rover designed to compete in the 2019 University Rover Challenge. For the competition’s Autonomous Traversal task, the rover must be capable of traversing difficult desert terrain in search of visual waypoints. Our design uses a custom Navigation Board (NavBoard), a mobile robotics computer, and a sensor capable of producing a dense point cloud. NavBoard provides quaternion-based orientation data, distance measurements from a 1D LiDAR system, and GPS data over ethernet to a mobile robotics computer. This computer derives a 3D point cloud from a three-headed collinear stereoscopic camera then processes that data along with the data from NavBoard to determine the correct action to navigate through sparsely mapped terrain.
  • Intelligent Monitoring Technology of Flight Test Based on Automatic Identification of Test Points

    Shenghu, Liu; Zhe, Yang; Bing, Ye; Chinese Flight Test Establishment (International Foundation for Telemetering, 2019-10)
    As the smallest component unit of the flight test task, test point defines the tasks and requirements to be completed by the test aircraft, which is the main basis for the flight effect evaluation. This article through in-depth analysis parameters variation characteristics of the testing aircraft in different test points, combined with the prior knowledge that the domain experts artificial recognize test points, extraction the key parameters of influencing test point identification, and their change rule. We constructed the knowledge base for test point identification, designed test point automatic identification algorithm. Combined with the flight test real-time task evaluation technology, we developed the real-time monitoring system for flight test based on the test point automatic identification and intelligent evaluation. It realized the change from the "intelligent security monitoring" to "intelligent task monitoring", and effectively improve the flight efficiency of the test aircraft.
  • VALIDATION PROTOCOL - THE MISSING PUZZLE PIECE

    Moskal, Jakub; Whittington, Austin; Morgan, Jon; Kokar, Mitch; Abbott, Ben; VIStology Inc; Southwest Research Institute; Edwards AFB (International Foundation for Telemetering, 2019-10)
    In multi-vendor T&E systems, a single hardware vendor cannot anticipate the dependencies on the settings from hardware manufactured by other vendors, or the systemic constraints that are specific to a particular customer. The T&E community has recognized the fact that MDL and TMATS XML are not sufficient to addresst his problem alone, and that there is a need for a separate, constraints language. Constraints written in such a language can be validated by a third party validation engine, without relying on any particular vendor’s software. To this end, we developed the concept of TACL, a candidate for the standard constraint language, and demonstrated it with a reference implementation of a TACL engine integrated with the iNET System Manager. In this paper, we argue that this integration should be standardized in the form of a Validation Protocol in order to turn the existing system into a loosely-coupled, standards-based architecture.
  • Design of Airborne Real-time Monitoring System for Vibration Signal of Large Civil Aircraft

    Jiayi, Liang; COMAC Flight Test Center, Instrumentation Dept (International Foundation for Telemetering, 2019-10)
    The high frequency vibration signal can effectively reflect the structural strength of aircraft during flight test. In order to meet the need of real-time monitoring of vibration parameters of a large civil airliner, an airborne real-time monitoring system for vibration signals is designed and developed. Development of airborne real-time monitoring software for high-frequency signals was based on C#. The software received and analyzed the network data of the airborne acquisition system, processed the time domain signals by FFT and power spectrum transformation, and realized the graphical display. The software can provide a strong support for the monitoring person to know the status of the aircraft in time.
  • A SYSTEMS ENGINEERING APPROACH TO MASTER MEASURAND LISTS AND THEIR METADATA

    Wells, Billy W., Jr.; Northrop Grumman, Corp. (International Foundation for Telemetering, 2019-10)
    A systems engineering approach to master measurand lists allows the use of metadata to improve data organization and management. As data acquisition systems become more complex, the management of sensors and their measurands must also advance. Traditional tabulated measurand lists of several hundred measurands are typically generated from email or verbal requests. Modern data acquisition systems with thousands of measurands are more complex than ever, causing these tabulated spreadsheets to become unwieldy and unmanageable. Modern data structures can easily organize and archive these lists through measurand metadata. By aligning the requirements of the measurand database with data acquisition system requirements, designers can ensure their data acquisition system is within constraints such as bandwidth, storage capacity, power consumption, size, and weight.
  • DATA COLLECTION AND ANALYSIS TECHNIQUES FOR SOLAR CAR TELEMETRY DATA

    Rouse, Michael; Sauer, Miranda; Kosbar, Kurt; Missouri University of Science and Technology, Dept Electrical and Computer Engineering (International Foundation for Telemetering, 2019-10)
    Data collected from a solar car is monitored in real-time, which allows for intelligent decision making, efficient debugging, and high-quality testing for solar car teams. This paper compares three databases (MySQL, PostgreSQL, and MongoDB) to determine the optimal database system that should be used at solar car competitions. Each database system was tested using simulated solar car data to measure read and write speeds, and quality of performance on a low-power computer. Data were analyzed and displayed with custom interfaces to improve the user experience at solar car competitions.
  • DESIGN AND RESEARCH OF REAL-TIME MONITORING PROGRAM DEVELOPMENT SYSTEM FOR CIVIL AIRCRAFT FLIGHT TEST DATA BASED ON WPF

    Mao, Wei; Feng, Can; Liu, Tao; Wang, Feng; Liang, Jiayi; Flight Test Center of the COMAC, Instrumentation Dept (International Foundation for Telemetering, 2019-10)
    The real-time monitoring program offlight test data is an indispensable and important supporting tool in the flight test of large civil aircraft. With the continuous deepening of the networked test system, a large number of complex flight test parameters pose a huge challenge for the development of monitoring programs. Based on the WPF platform, this paper uses XAML files, reflection and DataBinding to design a system for developing real-time monitoring programs for flight test data. The system realizes the rapid integration and management of the monitoring program by dragging and displaying the control, shortening the preparation cycle in the past few weeks to several hours; when the system is running, the three-layer architecture can drive hundreds of monitoring terminals in real time, which is the domestic large-scale passenger aircraft C919 aircraft. The first flight and forensic flight test provided technical support.
  • LTE-BASED AERONAUTICAL MOBILE TELEMETRY - LAB AND FIELD TEST EXPERIMENTS

    Beck, Eric; Erramilli, Shobha; Habiby, Sarry; Johnson, William; Kogiantis, Achilles; Maung, Nan; Rege, Kiran; Sayeed, Zulfiquar; Triolo, Anthony; Young, Jeffrey; et al. (International Foundation for Telemetering, 2019-10)
    Aeronautical mobile telemetry (AMT) based on 3GPP’s LTE standard is implemented in a proof-of-concept system. The solution tackles the very high Doppler shifts expected in flight tests using an appliqué that can be inserted between the transmit/receive ports of the Test Article (TA) and the antennas. This appliqué estimates the Doppler shift and proactively compensates for it on the uplink signal being transmitted by the TA. The overall system has been tested under different operational conditions in a laboratory setup as well as in the field. In the laboratory setup, the desired operating conditions are created with a set of Software-Defined-Radio-based channel emulators coupled with a computer to control their behavior. In order to carry out field tests, an operational LTE network has been created at Edwards Air Force Base (EAFB) with two base stations, backhaul links, and a core network. In this paper, we provide descriptions of both laboratory and field test setups as well as the results of several tests that have been carried out to date. The results of lab and field tests lend strong support to the viability of this AMT solution.
