The space shuttle, shown in Figure P9.9 (a), carries large payloads into space and returns them to earth for reuse [19]. The shuttle uses elevons at the trailing edge of the wing and a brake on the tail to control the flight during entry. The block diagram of a pitch rate control system is shown in Figure P9.9 (b). The sensor is represented by a gain. H(s) = 0.5, and the vehicle by the transfer function
The controller Gc(s) can be a gain or any suitable transfer function, (a) Sketch the Bode diagram of the system when Gc(s) - 2 and determine the stability margin, (b) Sketch the Bode diagram of the system when
The gain Kp should be selected so that the gain margin is 10 dB.

In the National AIDS Behavioral Surveys sample of 2673 adult heterosexuals, 0.2% (that's 0.002 as a proportion) had both received a blood transfusion and had a sexual partner from a group at high risk of AIDS. Explain why we can't use the large-sa..
It was suggested that the number of particles in a randomly selected interval might follow a Poisson distribution. Assuming a Poisson distribution to be an appropriate model for the data, use two methods to find an approximate 95% confidence inter..
