Seats

Closed.

Its lecture reads closed (100 of 100 · 1 over enrolled): you attend both, so this seat is not one you can take while that holds. There is no waitlist either, so the only way in is somebody dropping the lecture.

This discussion only. You also attend Lec 1.

Final

Read 6 hours ago. The latest refresh is overdue. Seats and instructors may have changed since. Check the registrar before enrolling.

dibs has seen this section open 7 times since 18 August. The last time was 22 September. 2 of those were readings where the capacity figure moved and the enrolled count did not, so dibs could not tell whether a seat existed and did not send an alert.

Watching is the one thing here that needs an account, because an alert needs somewhere to go. Everything else on this page works signed out.

Put this class on a board

A board is one quarter you are drafting, so it needs an account to live in. Signing in brings you straight back to this page, with this class still in front of you.

Before you can enroll

Registrar's Restrictions cell, read 3 days ago: "Undergraduate School of Engineering Majors, and Undergaduate Aerosapce Engineering or Mechanical Engineering Majors".

Tell dibs what you have already taken and this line will say which of these you have. Your list.

From the registrar

Students who enroll in upper-division courses offered by the Samueli School without completing the requisites are subject to disenrollment after the second class meeting. If necessary, consult with an OASA counselor through MyUCLA Message Center.

Restrictions read 3 days ago. dibs re-reads these slowly because they rarely change; watch the section and it moves to every 6 hours.

dibs read 127 of the 905 hours its hourly record covers, 14%, and did not look in 778. dibs had no hourly record before 25 Aug, which is the other 151 of 1056 plotted.50 of 50 enrolled at the newest reading, 6 hours ago, and no seats left. Seats from 18 Aug 19:40 to 1 Oct 18:33, 44 to 50. dibs read 127 of the 905 hours its hourly record here covers, 14%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 778 hours dibs was keeping a record and did not reach this section. Nothing before 25 August at 02:00, where this section's record starts, has a read either way, which is 151 hours of this window. Where the drawing is faint or broken, that never means the readings are doubtful. It means the stretch between them is unaccounted for.

A dot is a reading where something moved: the seat count, the status, or the waitlist. Flat between dots joins recorded counts; changes between reads may be missed. The line starts when dibs first saw this section rather than reaching back before it existed. The last one is the last time dibs read this section, moved or not, and that was 6 hours ago. It is where the line stops, not where the count is now.

How readings and alerts work

A reading and an hourly record are different things, and most charts here hold more of the second missing than present. dibs has taken readings of a section since long before it began keeping an hour-by-hour log of when it looked, so the empty stretches are dibs saying it was not keeping that log yet, not that it looked and found nothing. That is the age of the record and not a fault.

Seat counts show the last successful read, not live availability. Refreshes can be delayed by request limits or upstream interruptions. Watched sections receive priority, but an hourly update for every section is not guaranteed.

The registrar can change a seat count between our checks. Alerts depend on dibs detecting an opening and completing delivery; a quiet watch does not prove that no seat opened. Check the registrar before enrolling.
