A 220 V, 1500 rpm, 11.6 A (armature current), separately excited motor is con- trolled by a single-phase, full-wave SCR converter. The armature resistance of the motor is 2 n. The ac source voltage is 230 V (rms) 60 Hz. Enough induc- tance is added to ensure continuous conduction for any torque greater than25% of rated value. (Ignore the rotational losses.)a. Calculate the triggering angle for a speed of 1000 rpm at rated torque. b. Assuming that the torque is a fan-type, calculate the triggering anglefor a motor speed of 900 rpm. c. Sketch the speed-torque characteristics showing the operating pointsof cases (a) and (b).

Suppose host A is sending a large file to host B over a TCP connection. The two end hosts are 20 msec apart (40 msec RTT) connected by a 1 Gbps link. Assume that they are using a packet size of 1000 bytes to transmit the file. For simplicity, ignore ack packets. The TCP sender is transmitting with successive windows of 64KB every RTT over a loss-free 1 Gbps channel that has a 20 msec one way delay.At least how big would the window size (in packets) must be for the channel utilization to be greater than 70%? Show your work. (Note that for 100% efficiency, Window size = Maximum number of bits that can be transmitted in 1 RTT)

" Now consider a 1GHz processor without interrupts. This processor runs a dedicated polling routine (the processor is designed to handle exactly one event, using polling). The processor checks the hardware for an event every 500ns and the event handler takes 50 cycles to complete. Now, what is the minimum time from when an event occurs to when it is handled? What is the maximum time?"
