Aerospace Engineers Propose System for Automatically Detecting Vertical Flight Limits

Engineers at the School of Aerospace Engineering at the Georgia Institute of Technology have developed a system, which detects envelope limits for autonomous Unmanned Ariel Vehicles (UAV). The envelope limits ensure safety by restricting the aircraft's maneuverability. Automatic detection of those limits is crucial when performing aggressive maneuvers in varying flight conditions. This article reviews several models used in limit avoidance systems, critiquing them in terms of the system requirements and performance in simulation programs. The authors propose an alternative two-level system that calculates and communicates envelope limits online. Methodology, algorithms, derivations and integration software are described. Results from Software-in-the-loop Simulation and flight tests show the system was successful in keeping the vehicle within prescribed limits when performing a variety of maneuvers. [VF]

EPRI: Factors Related to the Series of Outages on August 14, 2003

A non-profit energy research consortium, the Electric Power Research Institute (EPRI), prepared a white paper, recently updated, describing its assessment of factors which may have contributed to the series of outages on August 14, 2003 in the United States and Canada. The study focused on systemic factors as well as specific operational and performance factors, but was not a root cause analysis. The authors note these are only "preliminary observations" given the limited timeframe and data available when the study was performed. [VF]

Two on Advances in Educational Technology

The Centre for Research in IT in Education (CRITE) [.mp3 and Quicktime]

Advances in technology can help children play and compose music. The first site describes a project of the Centre for Research in IT in Education, which draws from the field of cognitive development, learning styles theory and educational best practice to develop DrumSteps. This tool, available for downloading, enables children to create, manipulate, edit and save original pieces of percussion music. A user-tracking feature allows the teacher or researcher to follow along with student files click-by-click, giving valuable insights into the students' thinking. The Centre is also examining pedagogical issues surrounding a parallel project, which is described on the second site. Toy Symphony is a project of the MIT Media Lab and Media Lab Europe and offers software, which enables children to compose-by-drawing. The bulk of the project, however, develops specially designed Music Toys, which enable children to engage in sophisticated listening, performing and composing activities normally accessible only after years of study. Videos of the workshops, as well as live concerts in which children play alongside some of the world's most accomplished musicians, are also available to download. [VF]

Groklaw: Understanding Open Source Software

Mark Webbink, Red Hat's general counsel, wrote this article for attorneys wanting to know the basic issues regarding free and open source software. Aside from listing best practices for law offices, he provides a general overview of various open source licenses, explains US copyright law, defines derivative works, and touches on the indemnification issue and the difference between open source and shared source. Webbink also highlights some of the common myths and misconceptions about the General Public License (GPL) and open source and provides links to other sites with more information on open source software. Readers' comments and responses to the article are also posted in a threaded discussion format. [VF]

University of Washington, Department of Mathematics: Probability Abstract Service

Promoting the use of the internet and technology in education is not new. However, the use of technology, especially videos and web-based discussion groups, for teacher professional development is a recent development, spurring interest from state education policy makers, school districts and the technology industry giants. Some examples of these developments and issues to consider are examined in this Topic in Depth. [VF]

This article in the Christian Science Monitor (1) discusses some of the recent developments in web-based teacher professional development resources. The Teachers Network (2) is one example of an organization that identifies and exhibits innovative teacher practices. Teachers are able to watch videos of best practices and discuss pedagogical issues with teachers nationwide (Note that a number of these sites require registration, but the registration is free). Similarly, TAPPED IN (3) provides space for an international community of education professionals, including K-12 teachers and librarians, professional development staff, teacher education faculty and students, and researchers to engage in professional development programs and informal collaborative activities. The PBS Teacher Source (4) offers over 4000 lesson plans and activities in Arts and Literature, Mathematics, Science, Health and Fitness, Social Studies, Early Childhood, and Library Media. The AECT Project (4), funded by the U.S. Department of Education's Preparing Tomorrow's Teachers To Use Technology (PT3) grant program (5), has developed web-based tools that provide teachers with technological resources to use in their student assessments and instructional planning. These efforts are all in support of policies and standards developed by several states and organizations that encourage teachers to integrate technology into their instruction. For example, this website (6 ) describes a project of the International Society for Technology in Education (ISTE) to develop standards for the uses of technology that foster school improvement. This report by the U.S. Department of Education (7)
df}) reviews the past twenty years of technology policy in education, articulating key themes and approaches taken to integrate technology in education and offers recommendations for ways to support and sustain future investments. This article in EdWeek (8) provides some figures on current statistics for technology use in schools.
