Calculate the probability of a model ensemble that uses simple majority voting making an incorrect prediction in the following scenarios. how to use the binomial distribution will be useful in answering this question.)
a. The ensemble contains 11 independent models, all of which have an error rate of 0.2.
b. The ensemble contains 11 independent models, all of which have an error rate of 0.49.
c. The ensemble contains 21 independent models, all of which have an error rate of 0.4
With the switch, S1, closed in Fig, How much is the voltage across the switch? How much is the voltage across the lamp?
Discuss the types of inference that can and cannot be drawn from this study.
Design a Moore machine that has one input X and one output Z. Provide a complete design using D Flip flops. In this design, the output should be 1 any time the sequence 01101 occurs. Overlapping sequences are allowed.
A signal is sampled every 1ms for 20ms, with the following actual values of the analogue voltage at successive sampling times. Plot the values of the voltage recorder by a 5 volt, 4 bit ADC assuming that the noise level is much lower
Apply Mesh Analysis to calculate the current flowing through Resistor R2 in the below sketch:
A single phase two winding transformer having rating: 20 KVA,480/120 V, 60 Hz A source connected to the 480 V winding supplies an impedance load connected to 120 V winding. The load absorbs 15 KVA at 0.8 pf lagging when load voltage is118 V.
Design a circuit that will multiply the input voltage by +12. That is the output voltage is 12v1 where v1 is the input voltage. All resistors should be at least 12ohms.
A 400 V, 3-phase star connected alternator supplies a delta-connected load, each phase of which has a resistance of 30 and inductive reactance 40. Calculate the current supplied by the alternator
In this example we consider the time-domain waveforms corresponding to VSB modulation and consider demodulation using envelope detection or carrier reinsertion. We assume the same message signal as was assumed Example 3.4. In other words,
Two star-connected generators are connected in parallel and supply a balanced load of 1500 kVA at 11 kV line voltage and 0.8 lagging power factor.
Determine the force exerted on q2 by q1 if q1 = 3 x 10-4 C and q2 = -10-4 C and are located at point A(1, 2, 3) and point B(2, 0, 5). respectively.
A 10kW, 230V, 50 Hz, three-phase induction motor has full-loadefficiency of 86%, and power factor of 88%. It is supplied by a three-core cable 100mlong, having conductors of cross sectional area 16 mm^2 andresistivity 17.2nΩ m.
