1)Explain what a NUG is and why they have become important during the last 10 years.
2)Name which fuel is the most popular choice for NUG's and explain why they use it.
3)What factors started the decline in the nuclear power industry, and what events essentially ended new construction of nuclear power plants?
4)What are three advantages of using AC power over using DC power?
A 345-kV, 3-phase transmission line delivers 100 MVA, 0.866 lagging, to a DELTA connected load. Calculate the following: a.) The total real and reactive power delivered to the load. b.) The real and reactive power per phase.
placing the compensator or zero such that it will cancel the open-loop pole at -1. For both compensators you design, show the corresponding closed-loop transfer functions and compare the transient responses (P.O. and Ts).
A 2000kW synchronous motor operates at a three - phase line-to-line voltage of 4kV. It has a synchronous reactance of 4 ohms per phase. Calculate a) The nominal full load current of the machine when the excitation voltage E0 ( line - to-line) is 4k..
(a) If five different types of chips are to be placed on the board, how many different layouts are possible (b) If the five chips that are placed on the board are of the same type, how many different layouts are possible
A unit for a telecommunications system is to be designed so as to have a minimum availability of 0.9994. The MTTR (mean time to repair) for the unit is estimated to be 24 hours.
The network is used for voice communications. Is it possible for one mobile unit to connect to another mobile unit directly? What advantage is there in connecting through the hub?
generated by a loud speaker is reflected at two different walls with reflection coefficients r1 and r2. the signal x(t) recorded by amicrophone close to the loud speaker, after sampling is
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.
There are two four bit messages, 1010 and 1110. The first one is appended with an odd parity bit, the second one with an even parity bit. What are the values of the parity bits for the first and second messages respectively.
Design a DC power supply that provides -95v +/- 5v to a 2 amp load (energy absorber). The input source is a 100 volt peak sinusoid, 60 Hz. You may use any circuit element we've studied. State the values of all circuit elements
An LVDT with associated signal conditioning will be used to measure work-piece motion from -20 to +20 cm. The static transfer function is 2.5 mV/mm. The output will be interfaced to a computer via an ADC.
Two coupled coils have self-inductances L1 = 50 mH and L2 = 200 mH, and a coefficient of coupling k = 0.5. If coil 2 has 1000 turns, and I1 = 5Sin (400t) (i.e. the phasor current is 5? -90° A). Find the voltage at coil 2 and the flux through coil ..
