ATutor is an Open Source Web-based Learning Content Management System (LCMS) designed with accessibility and adaptability in mind.
Administrators can install or update ATutor in minutes, and develop custom templates to give ATutor a new look. Educators can quickly assemble, package, and redistribute Web-based instructional content, easily retrieve and import prepackaged content, and conduct their courses online. Students learn in an adaptive learning environment.
ATutor is the first fully inclusive LCMS, complying with the W3C WCAG 1.0 accessibility specifications at the AA+ level, allowing access to all potential learners, instructors, and administrators, including those with disabilities who may be accessing the system using assistive technologies. Conformance with W3C XHTML 1.0 specifications ensures that ATutor is presented consistently in any standards compliant technology.
ATutor has also adopted the IMS/SCORM Content Packaging specifications, allowing content developers to create reusable content that can be swapped between different e-learning systems. Content created in other IMS or SCORM comformant systems can be imported into ATutor, and visa versa. ATutor also includes a SCORM 1.2 Runtime Environment (LMS RTE3) for playing and managing SCORM based Sharable Content Objects (SCOs).
ATutors base in Open Source technology makes it a cost effective tool for both small and large organizations presenting their instructional materials on the Web, or delivering fully independent online courses. Comprehensive help is available through the ATutor HowTo documentation, through a number of support services, or through the public forums, and full language support is available through the ATutor Translation Site.

Main features:
- Forum Upgrades: Shared forums for communication across courses. Create communities around groups of course forums, or around an entire ATutor course server. Alumi participation in course forums. Subscribe to shared forums or course forums, or subscribe to specific topic threads to receive messages by email. Quickly access current forum messages through the Forum Posts menu module.
- File Manager Upgrades: Create new text and html files, move individual files or batches of files, and use the file manager while editing ATutor content pages. Use the Insert function to create links to files within course content pages and test questions.
- Enrollment Manager Overhaul: Create, import, and export course enrollment lists, and manage enrolled students or alumni. New tabbed display for managing student information, managing course lists, managing roles and privileges, as well as creating and managing groups.
- Language Overhaul: Language management has been completely re-designed. Translate, import, and export language from within an ATutor installation. Support for the UTF-8 character set. ATutor is avalable in more than 30 languages.
- Backup Manager: Administrator and Instructor Backup Manager. Create master copies of courses. Manage multiple backups per course and restore only material you specify into existing and newly created courses.
- Question Bank: Create tests by adding questions to, and retrieving questions from, a test item respository.
- Test/Survey Manager Upgrade: New ability to create image based test items, arrange multiple choice questions vertically or horizontally, assign tests to a class, to groups, or to individual students.
- Theme Manager: Easily copy, import, and export ATutor themes.
- RSS Feeds: Syndicate course announcements with RSS 1.0, or RSS 2.0 feeds, to display them on remote Web sites.
- New Feedback and Error Handling: Redesigned, modular, user feedback system. Improved logging, tracking, and presentation of system errors for debugging and troubleshooting ATutor installations.
- Embed ACollab: Embed ACollab into ATutor, or open it in a new window to participate in group activities.

- Easy Enrollment: Students can now enroll in courses through the Browse Courses screen.

Stanford Exploration Project Library (or SEP, for short) is an industry-funded academic consortium whose purpose is to improve the theory and practice of constructing 3-D and 4-D images of the earth from seismic echo soundings.
Although most of our research is targeted at improvements in the geophysical survey contracting industry, about half of our sponsors and alumni are in the petroleum industry because we focus on overcoming technological limitations of the geophysical survey industry.
SEP pioneered innovations in migration imaging, velocity estimation, dip moveout and slant stack. Today our focus is on 3-D seismic applications such as velocity estimation, wavefield-continuation prestack migration, multidimensional image estimation, and 4-D (time-lapse) reservoir monitoring.
Besides 3-D reflection seismic data, we undertake small 2-D imaging projects with geophysical data of all kinds. The diversity of applications exercises our judgment and skill at combining fundamentals of statistical signal theory, optimization theory, numerical analysis, and wave propagation theory, and this has led us to numerous improvements and some breakthroughs.
We organize our research to facilitate technology transfer by using a formal method of makefile rules. With these, most of our research results are verified by someone other than the original researcher. Research progress reports at least four years old and all PhD theses are made available to the public through our web site.
Enhancements:
- Numerous major new features and major bugfixes.
