Failure of Harmonic Gears During Verification of a Two-Axis Gimbal for the Mars Reconnaissance Orbiter Spacecraft

The Mars Reconnaissance Orbiter (MRO) spacecraft has three two-axis gimbal assemblies that support and move the High Gain Antenna and two solar array wings. The gimbal assemblies are required to move almost continuously throughout the mission's seven-year lifetime, requiring a large number of output revolutions for each actuator in the gimbal assemblies. The actuator for each of the six axes consists of a two-phase brushless dc motor with a direct drive to the wave generator of a size-32 cup-type harmonic gear. During life testing of an actuator assembly, the harmonic gear teeth failed completely, leaving the size-32 harmonic gear with a maximum output torque capability less than 10% of its design capability. The investigation that followed the failure revealed limitations of the heritage material choices that were made for the harmonic gear components that had passed similar life requirements on several previous programs. Additionally, the methods used to increase the stiffness of a standard harmonic gear component set, while accepted practice for harmonic gears, is limited in its range. The stiffness of harmonic gear assemblies can be increased up to a maximum stiffness point that, if exceeded, compromises the reliability of the gear components for long life applications

Impact and Concerns Related to Electronic Records Management and Storage

Electronic document or records management systems have been around for several decades. New technologies have evolved in recent years that provide new and expanded opportunities for organizations to use this electronically stored information in new ways. These storage technologies have also increased the number of real and potential problems, both short and long term, for technology managers. The purpose of this paper is to provide a brief outline of some research in process being done by the authors in the area of electronic document management and to invoke suggestions from other researchers

From teacher to learner: Using digital technology to enhance authenticity and engagement in poster presentations in the classroom and online

Over the past few decades, we have witnessed a rapid shift from traditional classrooms to digital learning environments. This shift has allowed for the creation of a more dynamic and interactive educational landscape. Students are now afforded learning opportunities that most of us could have only dreamed of with information and digital solutions at their fingertips. However, along with this increase in educational learning opportunities comes a distinct need for educators to continuously adapt and evolve their teaching and educational content to meet the needs of their digitally savvy student cohort. This can be a challenge as academics are often hesitant to engage with and learn new technologies and frequently lack the time to invest in developing digitally relevant material and assessments to meet the needs of the changing student cohort. In 2022, Federation University joined collaborative forces with Adobe and launched a program for academic teaching staff titled ‘Adobe Innovation Champions Pilot program’. The aim of this program was to engage staff in innovative digital technologies to improve pedagogical outcomes in their classrooms. The program facilitated staff to bring to the table novel ideas and to learn how to use the Adobe suite of products to develop innovative solutions to teaching deficits in their classrooms. This presentation provides an insight into the author’s engagement and experience with this program and the development of an interactive online poster presentation format from idea to delivery. It outlines how quickly digital technology can transform educational delivery and how these can be adapted and changed to meet educator and student needs. The result was an interactive online poster gallery created through Adobe XD, a software platform focused on website building.  However, with some academic creativity and lateral thinking, the Adobe XD platform was engaged with in a manner different to its intended purpose.  This saw students interact with scientific conference posters comprehensively before a presentation session, whilst also enabling the platform to be used as the poster presentation itself, resulting in seamless content delivery

The Fair Housing Act After Inclusive Communities: Why One-Time Land-Use Decisions Can Still Establish a Disparate Impact

The Fair Housing Act (FHA) is a civil rights statute that prohibits housing discrimination against several protected classes. One theory of liability under the FHA is disparate impact, in which a plaintiff alleges that the defendant’s policy or practice, although facially neutral, nevertheless has discriminatory effects because it disproportionately negatively affects a protected class. In its 2015 opinion, Texas Department of Housing and Community Affairs v. Inclusive Communities Project, Inc., the Supreme Court affirmed that the FHA includes disparate impact liability but also potentially limited its applicability—the Court distinguished between a defendant’s policy and a one-time decision by a defendant, hinting that the latter might not be able to substantiate a disparate impact claim. This Comment argues that such a distinction is unfounded. One-time land-use decisions should not be categorically excluded from disparate impact liability under the FHA for three reasons. First, one-time employment decisions may serve as the basis for disparate impact liability under two analogous civil rights statutes— Title VII and the Age Discrimination in Employment Act—indicating that the same is true for one-time land-use decisions under the FHA. Second, the distinction between a policy and a one-time decision is untenable and provides little guidance for courts. Third, seminal appellate court cases which first established disparate impact liability under the FHA involved one-time land-use decisions, indicating that such decisions constitute the heartland of disparate impact theory. The Comment concludes by providing further clarity about which particular one-time land-use decisions should enable litigants to establish successful disparate impact claims. It argues that claims based on zoning decisions and closures of residential buildings should be per se permitted, but that other claims may be less successful or altogether excluded. Ultimately, absent the inclusion of one-time land-use decisions as a basis for disparate impact liability, the FHA will lose much of its power as a tool to combat residential discrimination, segregation, and inequality in the land-use context
