Consider a 3 x 3 voq switch that we studied in class. here, there are three input queues at each port, which hold packets bound for the three output ports (a total of nine queues). for example, q13 is the length of the queue (in packets) at input port 1, which are destined for output port 3. suppose that we denote a matching using the notation in which [13 22 31] indi cates that one packet each from the queues q13, q22 and q31 are sent to the output ports 3, 2 and 1 respectively.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
