• Neutrality is Polite Oppression: How critical librarianship and pedagogy principles counter neutral narratives and benefit the profession

      Ferretti, Jennifer A.; Maryland Institute College of Art (The University of Arizona, 2018-11-28)
      The debate about whether or not libraries and information professionals should be neutral seems perpetual. Championing neutrality over a critical perspective intentionally furthers the oppression of not only marginalized patron populations, but of marginalized colleagues. Rooted in principles of critical pedagogy and critical librarianship, this talk will illustrate how neutrality impacts the information professions and the communities we serve, as well as ways in which our expectations of our students to critically evaluate sources can be applied to our own work. We ask our students to think about what information is missing within a resource. It’s time we not only ask our profession the same (who isn’t at the table, what isn’t being discussed, etc.), but also that we take action to counter narratives of neutrality in our everyday practices, including in the classroom and our work spaces.
    • Critical Approaches to Evaluating Student Privacy & 3rd Party Apps

      Unknown author (The University of Arizona, 2018-11-16)
      This information literacy resource was created by participants and facilitators during a workshop titled "Student privacy & third-party apps : Examining a university’s Terms of Service" at CLAPS 2018. Through reading actual contracts between technology vendors and the University or Arizona, the group of academic librarians, library administrators, and faculty developers synthesized the steps to take and information to look for in these contracts to better understand how student and worker information is collected and used by third-party vendors.
    • Contested Sites of Critical Library Pedagogy

      Almeida, Nora; Beilin, Ian; New York City College of Technology, CUNY, Brooklyn, NY; Columbia University, New York, NY (The University of Arizona, 2018-11-16)
      In this presentation we will explore critical library pedagogy in relation to different physical places and dialogic spaces. Using the idea of the library as a “third space” as a point of departure, we will consider whether alternative spatial contexts or modes of analysis might enable new forms of critique that are embodied, culturally grounded, and creative.
    • Design Thinking in an Hour? Or, Design Thinking: A Cautionary Tale

      Arteaga, Roberto; Pacific Lutheran University (The University of Arizona, 2018-11-16)
      Design thinking (DT) is a methodology that has become popular across many sectors due to its iterability and flexibility. As its adoption spreads throughout higher education settings, DT is now starting to appear in library literature and conferences. As teaching librarians, we may be tempted to adapt popular methodologies in the hope of increasing the reach of our work, considering how undervalued and misunderstood our work can be, but we should also consider whether DT is a potentially harmful practice. By discussing DT, what it can do, and where it can be most useful, I will present a case for why librarians who teach need not engage in a practice that treats learning as something that needs a solution and appears to sideline students and their lived experiences. Those who practice critical librarianship would be better served by adopting a student-centered pedagogy that shifts power and agency to the students, while simultaneously educating others on the work they do, why they do it, and how it contributes to student learning.
    • Practising Digital Pedagogy Librarianship: Building Critical and Queer Feminist Communities

      Patel, Kush; Cong-Huyen, Anne; University of Michigan (The University of Arizona, 2018-11-16)
      This workshop, led by the Digital Pedagogy Librarians at the University of Michigan Libraries, aims to address the nature and nurturing of digital pedagogy librarianship beyond its relationship to digital tools to ask: what roles do critical and queer feminist principles play in enriching our approaches to digital pedagogy and how might we constitute mutually transformative communities of practice around those principles?
    • Teaching CRAAP to Robots: Artificial Intelligence, False Binaries, and Implications for Information Literacy

      Seeber, Kevin; University of Colorado Denver (The University of Arizona, 2018-11)
      Researchers studying artificial intelligence and semantic computing are developing algorithms capable of processing large amounts of textual data and rendering judgment on its contents. Specifically, the field of sentiment analysis is focused on creating code that applies what programmers call “common sense” to evaluate whether writing is factual or opinionated, as well as how emotional the author was. This presentation will argue that these algorithms rely on false binaries, over-simplification, and poorly-constructed checklists, similar to the approach often used when discussing information literacy with first-year college students. Instead of employing this approach, this session will argue that librarians must recognize that human interpretation lies at the core of information literacy, and that we need to embrace that complexity rather than depend on algorithmic evaluation.
    • Using Synchronous Posting to Locate Student Pain Points

      Binnie, Naomi; University of Michigan (The University of Arizona, 2018-11)
      The nature of undergraduate library instruction sessions means we often do not see the same students more than once. We rarely begin the class knowing students’ names, their majors, their confidence levels or how they’re feeling that day. I will discuss beginning my instruction sessions with a student activity featuring synchronous, anonymous posting in an effort to create a safe space and to empower students by centering their voices, particularly the voices of students from marginalized communities who may not feel safe in the typical classroom environment. I will discuss how I assess student needs, pain points, and confidence levels in the beginning of class rather than at the end.
    • Deconstruct to Reconstruct: Challenging Critical Librarianship

      Leung, Sofia; Pho, Annie; MIT; UCLA (The University of Arizona, 2018-11)
      The practice of critical librarianship is often viewed and approached in segmented pieces, due to the nature of specializations within the profession. Those who engage and practice critical librarianship often may focus on certain areas like pedagogy, archival theory, classification or categorization, and scholarly communication, among other topics. This presentation will deconstruct the core values of librarianship and rhetoric within critical librarianship in order to begin reconstructing and reimagining how libraries can explicitly center marginalized communities. We want to build a broader framework that explicitly draws the connections/relationships between critical pedagogy (how we teach), critical information literacy (what we teach), and the infrastructure, policies, and practices of the libraries within which we work. We will challenge western knowledge practices and engage participants in collectively developing a new framework of librarianship that will inform and shape our pedagogy.

    • CODEBOOK BASED TECHNIQUES FOR HIGH-PERFORMANCE GEOLOCATION

      Yang, Andrew; Goldsworthy, Dylan; Nakamura, Drew; Hua, Lee; Univ California Santa Barbara, Department of Electrical and Computer Engineering (International Foundation for Telemetering, 2018-11)
      Conventional geolocation techniques were developed based on time-delay estimation, followed by computation of the angle of arrival (AOA). The AOA computation is the main cause of latency, which significantly degrades the feasibility of real-time bearing-angle detection. The computation also adds to hardware complexity and power consumption, which is critical for small, light-weight and mobile devices. This paper presents a codebook based approach to geolocation. The delay profiles are mapped to a precomputed codebook to match the optimal estimation of the geolocation. This simplifies the computation procedure and makes real-time computing feasible. It utilizes limited memory capacity to reduce latency and hardware complexity. This approach also allows us to accurately assess the resolving capability. In addition, it reduces computation for joint estimation with multiple receiver units, especially in mobile format.
    • REAL-TIME MONITORING TECHNOLOGY OF INLET DISTORTION SIGNAL

      Huang, Ruchang; Wei, Guobo; Wang, Zhongjie; Li, Panwen; Chinese Flight Test Establishment (International Foundation for Telemetering, 2018-11)
      In the flight test, the matching compatibility of the fighter inlet and the engine is the key to the test flight of the engine performance quality. Especially at high incidence of high attack angle and over stall maneuver, the characteristics of the inlet are very important to the engine. The current traditional test scheme cannot real-time telemeter the inlet distortion signal.This paper aims at the problem by designing an embedded airborne real-time processing unit which can real-time calculate and telemetry of the inlet distortion signal. Then the results are displayed in the ground monitoring station by cloud image mode. So we can evaluate the matching performance of the inlet and engine during aircraft flight, and achieve the aim of prejudging the risk of inlet distortion.
    • WIRING HARNESS CONSTRUCTION AND DATA PROTOCOL SELECTION FOR HIGH NOISE APPLICATIONS

      Schultz, Aaron; Marcellin, Michael; Univ Arizona (International Foundation for Telemetering, 2018-11)
      The main problem with wired data transmission is exposure to electrical noise. In environments with extremely high noise levels, special care needs to be taken in order to accurately send data between two or more devices. In the case of motorsports, extreme noise on any critical data lines can cause engine failure, putting the driver’s safety at risk. The purpose of this paper is to explain effective construction techniques for noise reduction in a wiring harness, as well as to review how certain serial data protocols will handle errors in harsh conditions.
    • Progress in the Migration of Flight Test Analysis Routines to Python

      Bretz, John C.; Symvionics, Inc., IADS® Development Group (International Foundation for Telemetering, 2018-11)
      In recent years, the Python language and its associated scientific libraries have been enjoying increasing acceptance. Scientific Python’s ability to replace MATLAB® for many disciplines makes its consideration as an alternative imperative. Python is popular in the engineering academic arena; many entry-level Engineers have experience coding engineering tools in Python already due to its open-source nature and status as a low-cost, low-risk alternative to MATLAB. The IADS Development Group (IDG) has been working on uses of Python and ways to allow users to write Python code from within IADS to help streamline their data processing efforts. This paper will document the progress made since 2015. Experience gained with some of the available Python libraries will be shared, and various tools that have been developed in Python by IADS programmers for their users will be introduced and described in detail. An attempt will also be made to assess the acceptance of Python in the Flight Test community.
    • Homing and Docking Algorithms for Circular Transmission and Receiver Arrays

      Radzicki, Vincent R.; Hua, Lee; Univ California Santa Barbara, Department of Electrical and Computer Engineering (International Foundation for Telemetering, 2018-11)
      Homing and docking are two major components in the navigation of UAV’s and UUV’s. It involves the estimation of the six-element displacement vector based on the received signals, where three of the vector elements are associated with the translational displacement and the other three are for the rotation vector. The homing procedure is based on the estimation of the rotation vector with far-field approximations. In the docking range, the displacement estimation becomes more sensitive and critical. Far-field approximation-based algorithms are no longer effective, and high-precision techniques become important and need to be developed. In this paper, we examine and model the multi-dimensional displacement estimation for circular arrays. It allows us to accurately assess the performance as well as the limitation of the algorithms, with respect to various system parameters such as the size of the arrays, range distance, transmitted waveforms, and signal processing algorithms.
    • Spectrum Access R&D (SARD) Program: Broadband Conformal C-Band Antenna Project

      Currently in the second year of development, Broadband Conformal C-Band Antenna (BCCA) is being transitioned and matured out of prototyping phase. This paper will discuss encountered challenges in designing, optimizing, and developing a weapon system telemetry antenna operating in C-Band spectrum.
    • ANTENNA PRECISE POINTING CALIBRATION USING LOW COST DGPS

      Rubio, Pedro; Alvarez, Jesus; AIRBUS DEFENCE & SPACE Flight Test (International Foundation for Telemetering, 2018-11)
      Pan&Tilt directional antennas are present in every Airspace Test Center. They are used to receive telemetry data from the target in test (usually a rocket or an aircraft). Required telemetry range can be usually around 200nm which leaves no option but to use directional antennas (parabolic among others). The use of directional antennas greatly enhances the telemetry range by a factor of 1000. But it does it at a cost: directional accuracy. This kind of antenna has a narrow radiation pattern with its nominal gain at the center of the antenna dish. The main beam of the radiation pattern can be as narrow as 1.8 degrees (3db) in a C Band 2.4m parabolic antenna. An antenna has to be pointing its radiation pattern main lobe to the flying target with an error of less than the main lobe width in order not to degrade reception. A method has been implemented to properly calibrate the mechanical pointing vector to overlap with the radiation pattern main lobe. The calibration method presented in this paper allows a very precise calibration that can be performed locally with the aid of DGPS, RF Beacon, RF Spectrum Analyzer and software to manage the whole process.
    • FLIGHT TEST DATA AIRBORNE RESTRUCTURABLE FAST FROCESSING TECHNOLOGY

      Wu, Zhenhua; Wang, Jianjun; Li, Xiaoya; Chinese Flight Test Establishment (International Foundation for Telemetering, 2018-11)
      In multi-bus, long-endurance flight test, the huge test data is recorded by networked airborne testing system. After the flight, to ensure that engineers can analyze engineering data immediately, the processing platform must use limited resources quickly to complete test data processing. Because the test parameters sets on different test tasks are different, we design an airborne restructurable fast data processing system: during the flight, uploading the phased data processing configuration information through telemetry uplink in real time according to the execution state of the ongoing test task, based on these task requirements, the airborne processing system restructures its processing logic and workflow, avoiding repeated calculation of parameters, and ensuring the limited onboard computing resources can meet the needs of multitasking comprehensive flight test data processing.
    • COMMON DATA PROCESSING APPLICATIONS ACROSS DECOMMUTATION VENDORS

      Bauer, William; Mann, Phillip; Raytheon Missile Systems (International Foundation for Telemetering, 2018-11)
      Traditional Decom Systems usually require vendor specific data descriptions and provide vendor specific processing capabilities. Using a Software Decom allows the Decom hardware to be setup with a minimal configuration. The added capability of a UDP Multicast over Ethernet for the framed decommutated data allows for common Applications to perform the heavy lifting of Archiving, Real Time Display, and Distributed Processing. Any PC listening on the Local Area Network can access the telemetry data in real-time. This allows common real-time displays, archival tools and data forwarding applications to all run simultaneously.
    • THE COAXIAL WAVEGUIDE ANTENNA - A NATURAL DESIGN FOR MULTI-BAND FEED APPLICATIONS

      Shea, Donald; Applied Antenna Technology (International Foundation for Telemetering, 2018-11)
      The coaxial waveguide antenna exhibits efficient multi-band operation in both tracking and nontracking applications. Radiation from coaxial waveguide operating in the TE1,1 mode produces an on-axis pattern similar to that of open-ended circular waveguide. A second mode, the TE2,1 mode, produces a difference pattern similar to that of a four arm spiral. An inner waveguide cavity operating in the TE1,1 mode and a concentric outer waveguide cavity simultaneously operating in the TE2,1 mode provides this antenna the ability to operate as a tracking feed. It is the intent of this paper to show how the coaxial waveguide antenna is ideally suited to meet many of today's antenna system requirements.
