NASA space station automation: AI-based technology review. Executive summary
Research and Development projects in automation technology for the Space Station are described. Artificial Intelligence (AI) based technologies are planned to enhance crew safety through reduced need for EVA, increase crew productivity through the reduction of routine operations, increase space station autonomy, and augment space station capability through the use of teleoperation and robotics
Report on the Twelfth United Nations/European Space Agency Workshop on Basic Space Science
Pursuant to recommendations of the United Nations Conference on the
Exploration and Peaceful Uses of Outer Space (UNISPACE III) and deliberations
of the United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS),
annual UN/European Space Agency workshops on basic space science have been held
around the world since 1991. These workshops contributed to the development of
astrophysics and space science, particularly in developing nations. Following a
process of prioritization, the workshops identified the following elements as
particularly important for international cooperation in the field: (i)
operation of astronomical telescope facilities implementing TRIPOD, (ii)
virtual observatories, (iii) astrophysical data systems, (iv) concurrent design
capabilities for the development of international space missions, and (v)
theoretical astrophysics such as applications of nonextensive statistical
mechanics. Beginning in 2005, the workshops focus on preparations for the
International Heliophysical Year 2007 (IHY2007). The workshops continue to
facilitate the establishment of astronomical telescope facilities as pursued by
Japan and the development of low-cost, ground-based, world-wide instrument
arrays as lead by the IHY secretariat.Comment: PDF, 9 page
NASA space station automation: AI-based technology review
Research and Development projects in automation for the Space Station are discussed. Artificial Intelligence (AI) based automation technologies are planned to enhance crew safety through reduced need for EVA, increase crew productivity through the reduction of routine operations, increase space station autonomy, and augment space station capability through the use of teleoperation and robotics. AI technology will also be developed for the servicing of satellites at the Space Station, system monitoring and diagnosis, space manufacturing, and the assembly of large space structures
Integrating Prosodic and Lexical Cues for Automatic Topic Segmentation
We present a probabilistic model that uses both prosodic and lexical cues for
the automatic segmentation of speech into topically coherent units. We propose
two methods for combining lexical and prosodic information using hidden Markov
models and decision trees. Lexical information is obtained from a speech
recognizer, and prosodic features are extracted automatically from speech
waveforms. We evaluate our approach on the Broadcast News corpus, using the
DARPA-TDT evaluation metrics. Results show that the prosodic model alone is
competitive with word-based segmentation methods. Furthermore, we achieve a
significant reduction in error by combining the prosodic and word-based
knowledge sources.Comment: 27 pages, 8 figure
The potential of mobile phones to transform teacher professional development
Futures thinking is used by governments to consider long-term strategic approaches and develop policies and practices that are potentially resilient to future uncertainty. English in Action (EIA), arguably the world’s largest English language teacher professional development (TPD) project, used futures thinking to author possible, probable and preferable future scenarios to solve the project’s greatest technological challenge: how to deliver audio-visual TPD materials and hundreds of classroom audio resources to 75,000 teachers by 2017. Authoring future scenarios and engaging in possibility thinking (PT) provided us with a taxonomy of question-posing and question-responding that assisted the project team in being creative. This process informed the successful pilot testing of a mobile phone-based technology kit to deliver TPD resources within an open distance learning (ODL) platform. Taking the risk and having the foresight to trial mobile phones in remote rural areas with teachers and students led to unforeseen innovation. As a result EIA is currently using a mobile phone-based technology kit with 12,500 teachers to improve the English language proficiency of 700,000 students. As the project scales up in its third and final phase, we are using the new technology kit—known as the ‘trainer in your pocket’—to foster a ‘quiet revolution’ in the provision of teacher professional development at scale to an additional 67,500 teachers and 10 million students
