The cross section of a long cylindrical fuel element in a nuclear reactor is shown. Energy generation occurs uniformly in the thorium fuel rod, which is of diameter D = 25 mm and is wrapped in a thin aluminum cladding.
(a) It is proposed that, under steady-state conditions, the system operates with a generation rate of q = 7 X 108 W/m3 and cooling system characteristics of T8 = 95°C and h = 7000 W/m2 · K. Is this proposal satisfactory?
(b) Explore the effect of variations in q and h by plotting temperature distributions, T(r), for a range of parameter values. Suggest an envelope of acceptable operating conditions.
Write an assembly code segment that calls the subroutine New Function if bits 5 and 6 of PORTD equal 1. Write the same code segment in part (a) using structured assembly constructs.
Find the intrinsic gain of an NMOS Transistor fabricated in a process for which kn'=200 uA/V^2 and V'A =20 V um. The transistor has a 0.5-um channel length and is operated at Vov=0.25 V. If a 2-mA/V transconductance is required, what must ID and W..
a single phase transformer has the following ratings: 10kVA,240/2400V. In the open circuit test with rated primary voltage(240V), the primary current is 0.85A and secondary voltage is2400V. A short circuit test is performed as follows
When unmodulated the carrier voltage is 75 volts peak. An information (modulating) signal of 15 KHZ with 5 volts peak amplitude causes a frequency deviation of 22.5 KHz. If the load resistor RL= 100 Ohms, determine the following Modulation index
Create a vector containingsamples of the signal y(t)=x(t-5) for a=0.01 and T=10 over therange t=[0: a :T-a]. since x(t) is effectively zero for|t|>5, you can calculate CTFT of gthe signal y(t)=x(t-5) fromthe above analysis using N=T/a.
(a) Design a full subtractor cicuit with three inouts x, y,Bin, and two outputs D and Bout. The circuit subtracts x - y - Bin.Bout is 0 if no borrow is needed to complete the subtraction, and 1if a borrow is needed.
How do you use linearity to find a the actual value of (vo) when you are not given the values of the current, with just the assumption value of (vo)
Find the load dc current and find the rms of the ac current input to the rectifier - Plot the Simulink rectifier input voltage and load voltage on the same plot
A 12-bit ADC with a Vref of 5V is used to digitize small signals with a quiescent value of 2.5V and a variation around 2.5 of +/- 100mV. What is the SNR of the digitized signal if the ADC is ideal
The input/output relation of a discrete time system is given by y(n) = x(n+1) + x(n-3). Find an expression for h(n), the unit sample response of this system. specify how many non-zero terms there are in h(n).
Create a sequence detector that recognizes the following sequence on input X with overlap: "1011101", and sets the output Y to 1 when the sequence has been detected. a) Provide the state diagram and truth table showing the previous state
Design a 2-bit counter that, when f = 1, counts in the repeating sequence: 0, 2, 3, and when f = 0, counts in the reverse direction. Use T flip-flops. (a) Construct a state diagram or state table.
