Steel surfaces can be hardened by carburization. During one such treatment at 1000°C, there is a drop in carbon concentration from 5 to 4 at% carbon between 1 and 2 mm from the surface of the steel. Estimate the flux of carbon atoms into the steel (in atoms/(m2s)) in this near-surface region. ) The density of FCC- Fe at 1000°C is 7.63 g/cm3.
a.) What isthe minimum sampling frequency to avoid aliasing b.)If the sampling frequency of fs=2500 samples/sec is used how many samples must be taken to give a frequency resolution of 10Hz
Tune PI Parameters, Question: Given are the facts that Gc and Gp(s) are in series and Gp(s) = (K * Km) / [s[(Ls+R)(Js+b) + K^2m)]].
A pulse width modulation (PWM) circuit works by varying the duty cycle of the square wave while keeping the period fixed.
The forward-bias current in a GaAs pn-junction at T = 300 K is ID = 15 mA. The reverse-saturation current is IS = 10^-19 A. Determine the required forward-bias diode voltage.
A liquid level system converts a 4-10 m level into a 4-20mA current. Design a three mode controller (PID im assuming) that outputs 0-5 volts with 50% PB, 0.03 min integration time, and 0.05 min derivative time.
Determine ideal impulse response using inverse discrete-time Fourier transform. An ideal low-pass filter is described in the frequency-domain by
Plot the magnitude response (in dB) and the impulse response of the designed filter using MatLab.
Calculate the torsional spring stiffness constant for a steel shaft 0.5" in diameter and 2.5 ft long.
Power Systems Theory Definitions and Formulas, Define, (a) The fault level of a system or unit in a system, (b) base MVA
Sitting in front of you is a box; you cannot see iside the box. The box has a power cord that is plugged into a working wall socket. There is a wire coming out of the box; the end of the wire outside the box is exposed (not insulated) and is not c..
Consider the transformer to deliver its rated kilovoltamperes at 0.80 power factor lagging to a load on the low-voltage side with 240 V across the load. Find the highside terminal voltage.
Mrs. Brooke owns a robot with an FSM brain. The robot walks from left to right along a paper type containing a sequence of 1's and 0's. On each clock cycle, the robot walks to the next bit.
