- Number of Unregistered Users, identified by unique hosts/IPs, that had an active Session 10 without logging in. Does not include known web bots/crawlers.
- Number of Unregistered users, identified by unique hosts/IPs, that had an active session of less than 15 minutes without logging in and downloaded a non-interactive resource such as PDF or podcast. Does not include web bots/crawlers.
- Number of Registered Users2 that ran one or more simulation runs.
- All Unregistered Users, identified by unique hosts/IPs, that had an active Session 10. Does not include known web bots/crawlers.
- All Unregistered users, identified by unique hosts/IPs that downloaded a non-interactive resource such as PDF or podcast. Does not include known web bots/crawlers.
- Sum of Simulation Users 5 + Unregistered Interactive Users 3 including web bots/crawlers.
- Number of Simulation users that returned after a gap of 3 months.
- Begins when an IP is active on the site for at least 15 minutes. Ends when inactive for more than 30 minutes, including time spent viewing videos.
- Identified by a unique IP address / hostname.
- Based on MIT OCW metric of Visits: A visit is activity by a unique visitor delimitated by a 30 minute absence from the site on either side of the activity.
These visits correspond to unique visitors 11. Does not include known web bots/crawlers - Number of Simulation sessions that were shared between 2 or more users.
