1. Explain and classify the renewable energies.
2. Describe the conversion paths of solar energy.
3. What is the thermodynamic limit of solar energy conversion with a blackbody receiver?
4. Define the exergy of solar radiation.
paper on the use of one of the primary resources - Include the role that your chosen resource plays in power generation, along with any pros or cons of its use.
Assume that h is a random variable with PDF. Pn(h)=0.1*d(h-1)+0.9d(h-3). n is a zero mean white gaussian noise with variance 0.5. Assume that the channel state info is available at the reciever for each of the three branches.
If the breakdown voltage increases with temperature at a rate of 40 mV/"C, find the break-down voltage of the diode at room temperature, assuming that the space-charge resistance is 10 C& independent of temperature.
Iindicate whether the element involved is a capacitor, an inductor, or a resistor, and the value of C, L, or R if sufficient data are given
in a binary communication system a binary 0 is transmitted using an electrical pulse of magnitude 2.5v and a binary 1
How many flip-flops are needed to construct this FSM? Does your answer depend on the implementation approach (generic, seen in the previous chapters, or pointerbased, seen here)?
If the products are rounded as described in part (a), the output can be represented as yˆ[n] = y[n] + f [n] where y[n] is the output owing to x[n] acting alone, and f [n] is the total output due to all the noise sources acting independently. Deter..
Design a sequential system to continuously output your set of eight different digits (01275438) in binary at the rate of one digit per clock pulse.
A 6-pole, wave-connected dc armature has 300 conductors and runs at 1200 rpm. The emf generated is 600 V. Find the useful flux/pole.
A 120volt, 60Hz single phase load of 3.2KW with an inductive power factor of 8.1 needs to be corrected to a power factor of 0.95 (inductive). What capacitance value (in uF) is needed
a. The resistance of a copper wire is 0.92 Ω at 4°C. At what temperature (°C) will it be 1.06 Ω? - At what temperature will it be 0.15 Ω?
Is the second law satisfied? Will this refrigerator still satisfy the second law if its coefficient of performance is 6?
