Question 4. (25 points) Represent the following problem using TCSPs. Clearly show what the vents are. Convert the TCSPs into one or more STNs. Solve the STN(s) by creating the dis ance graph and obtaining the minimal graph (d-graph) using the all-pairs-shortest-path technique xplain the result. It is now 9:00am. The remote sensing station has an important maintenance scheduled at 10:30. Before the maintenance, one of the two experiments should be performed. The scientists can either use the Pierre Auger fluorescence detector to detect cosmic rays or use the photometric telescope for a survey. Each experiment takes 30 minutes. The absolute calibration of the Pierre Auger fluorescence detector relates the flux of photons of a given wavelength at the detector aperture to the electronic signal recorded by the FD data acquisition system, and takes 6575 minutes. The photometric telescope is self-calibrating but needs to cool down for 3040 minutes before being shut down for maintenance. Which experiment should the scientists work on
