Name: Change Flight Reservation Itinerary Description: A traveler who has an active flight reservation requests a flight itinerary change. The system [Automated TravelAgent] requests information from the traveler to identify her active flight reservation and flight itinerary change. If the proposed flight itinerary change (or a variation of it) can be made, the system effects the change. If the change cannot be made, the system explains why the proposed flight itinerary change request cannot be satisfied. Preconditions: The traveler has a valid system user and a valid travel account and an active flight reservation. Basic Flow: The traveler requests a flight itinerary change. The system retrieves current information about the status of the traveler's account, and asks the traveler to identify her active flight reservation, which can be identified by specifying either the record locator or the flight number, departure airport and departure date. [Exception: No active flight reservation located.] The system retrieves and displays the current flight itinerary and requests information about the NEW flight itinerary. The system checks to see if there are any available flights that satisfy the constraints of the proposed flight itinerary change. If there are available flights the system displays their flight schedules and airfares and requests that the traveler: 1) select one of the available flights; 2) reformulate the proposed flight itinerary change(Search criteria for the new flight be changed); or 3) cancel the proposed flight itinerary change. If the traveler reformulates her proposed flight itinerary change the system processes the request as before. If the traveler selects an available flight the system reserves the new flight, cancels the old flight, and updates the traveler's current flight itinerary and travel account. If there are no available flights, the system displays an explanation and recommends an alternative flight itinerary. [Exception: No more alternative flight itineraries to recommend. The use case terminates when the traveler selects one of the available flights or cancels the proposed flight itinerary change request. Postconditions: A traveler either retains her original active flight reservation or receives an updated flight itinerary with a new flight reservation. Otherwise: none.

For the circuit shown in figure PSS7-6, find $i_L(0^-)$, $i_L(0^+)$, $i_L(\infty)$, $i_C(0^-)$, $i_C(0^+)$, $i_C(\infty)$, $v(0^-)$, $v(0^+)$, $v(\infty)$, and $\frac{dv}{dt}|_{t=0^+}$. Determine $i_L(t)$, $i_C(t)$ and $v(t)$ for $t \ge 0^+$. Calculate the initial and final energy stored in the inductor. Assume that the switch has been in its starting position for a long time before moving at $t = 0$.
