The even registration system allows UT Dallas students, staff, and faculty to register university-sponsored events. Many events require several types of university resources. For instance, parking needs, unlocks, lockups, guards, and police officers need to be coordinated for events. The event registration system not only reserves the required resources for the event (assuming these are available for the event) but also informs the various departments that provide these resources about the reservation. Document the data contained in the event registration form usingthe data structure notation discussed in class. Event Registration data= Event data + Event Contact data + Request data + User data Event data= Event start date + Event start time + Event end date + Event end time + Event title

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
