STOLAND

The STOLAND system includes air data, navigation, guidance, flight director (including a throttle flight director on the Augmentor Wing), 3-axis autopilot and autothrottle functions. The 3-axis autopilot and autothrottle control through parallel electric servos on both aircraft and on the augmentor wing, the system also interfaces with three electrohydraulic series actuators which drive the roll control surfaces, elevator and rudder. The system incorporates automatic configuration control of the flaps and nozzles on the augmentor wing and of the flaps on the Twin Otter. Interfaces are also provided to control the wing flap chokes on the Augmentor Wing and the spoilers on the Twin Otter. The STOLAND system has all the capabilities of a conventional integrated avionics system. Aircraft stabilization is provided in pitch, roll and yaw including control wheel steering in pitch and roll. The basic modes include altitude hold and select, indicated airspeed hold and select, flight path angle hold and select, and heading hold and select. The system can couple to TACAN and VOR/DME navaids for conventional radial flying

Analysis and assessment of film materials and associated manufacturing processes for a solar sail

Candidate resin manufacturers and film producers were surveyed to determine the availability of key materials and to establish the capabilities of fabricators to prepare ultrathin films of these materials within the capacity/cost/time constraints of the Halley program. Infrared spectra of three candidate samples were obtained by pressing each sample against an internal reflection crystal with the polymer sandwiched between the crystal and the metal backing. The sample size was such that less than one-fourth of the surface of the crystal was covered with the sample. This resulted in weak spectra requiring a six-fold expansion. Internal reflection spectra of the three samples were obtained using both a KRS-5 and a Ge internal reflection crystal. Subtracted infrared spectra of the three samples are presented

Promises, pyramids and prisms: Reimagining postgraduate funding

The promises of upward mobility and social transformation are intertwined with the story of higher education in South Africa. In the years leading up to and in sync with the democratic moment of 1994, multiple selection programmes and academic development projects engaged with questions of potential (e.g., Yeld 2007; Miller 1992) particularly in relation to the inequalities of apartheid schooling and implications for higher education. While access and success have been widened in the decades since, and participation rates are more demographically representative, #FMF and #RMF challenged the myth of meritocracy. In a disillusioning political present, higher education resembles a giant pyramid scheme in which the investment of many delivers results for only a “lucky” few, particularly the higher up the ladder one ascends (Bradbury 2022). This prioritisation of the privileged continues despite official labour surveys demonstrating that each step along the higher education degree path increases individual employment prospects and contributes to socioeconomic productivity.  The focus of this article is on funding for postgraduate students who represent the intellectual future both within the academy and beyond, developing high level skills for the knowledge economy to solve the “wicked problems” of the 21st century. Inherited funding models reward individual excellence, treating students as isolated individuals, falsely assuming supportive middle class family networks and conceiving of study years as a temporal sequestration from communal responsibilities and projected future working life. In reality, the borders between home and campus, between studies and work, between (extended) childhood and adulthood, are far more porous. These funding models are unsustainable, irrational and unethical, and premised on “cruel optimism” (Berlant 2011) rather than the promise of radical forms of hope. The article presents some pragmatic possibilities for reimagining funding for postgraduate studies in South Africa in the present. It is however imperative that these responses attend to both the past and the future to create conditions of “freedom in security” (Manganyi 1973) in which individual and collective potential can be actualised for a more equal future

Pedagogy First, Technology Second: teaching & learning information literacy online

This paper explores the pedagogical and technical issues, challenges and outcomes of creating an online information literacy course. Currently under development, this course will be offered as a parallel study option to Advanced Information Retrieval Skills (AIRS:IFN001 ) for QUT postgraduate students, a compulsory face-to-face course for all QUT research students. The aim of this project is to optimise students’ access to AIRS:IFN001 and meet the University’s objectives regarding flexible delivery and online teaching. Still in its developmental stages, AIRS::Online extends beyond the current notion of static online information literacy tutorials by providing a facilitated, student focussed learning environment comprising content and learning experiences enhanced by appropriate multimedia technology and resources which engage students in planned facilitated and/or self-paced learning events. Course assessment is formative and summative, and is comprised of a research log and reflective journal to provide a means for reviewing the content and key process of advanced information searching and retrieval
