Usage: Overview

As part of nanoHUB’s continued effort to provide valuable statistics, parts of the usage overview page may be temporarily unavailable as we implement improvements.

During this transition, historical usage data and site metrics will remain available. Site data continues to be logged and processed to maintain continuity with existing usage statistics.

Some references may be missing depending on the data available.

  1. Number of Registered Users2 that ran one or more simulation runs.
  2. Number of Simulation users that returned after a gap of 3 months.
  3. Identified by a unique IP address / hostname.
  4. 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
  5. Number of Simulation sessions that were shared between 2 or more users.
