Consider a bidirectional link that uses Go-Back-N with N = 7. Suppose that all frames are one unit long and that they use a time-out value of 2. Assume the propagation is 0.5 unit and the processing time is negligible. Assume that ACK (Acknowledgment) timer is one unit long. Assuming stations A and B begin with their sequence numbers set to zero, show the pattern of transmissions and associated state transitions for the following sequences of events (Explain with diagram)(a) Station A sends 6 frames in a row, starting at t = 0. All frames are received correctly. (Explain with diagram)(b) Station A sends 6 frames in a row, starting at t = 0. All frames are received correctly, except frame 3 is lost. (Explain with diagram)(c) Station A sends 6 frames in a row, starting at t = 0. Station B sends 6 frames in a row, starting at t =0.25. All frames are received correctly. (Explain with diagram)

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
