The gradient is perpendicular to surfaces of constant scalar quantities. Show how this property can be used to:
(a) Find surfaces of constant scalar values.
(b) Find the normal unit vector to a surface at a point.
The converter canreceive signals from 0 V to 5.0V. Design the electronic processorthat must be connected between the sensor´s output and thecomputer´s converter A/D input; so that maximum sensibility is obtained. Justify each single proposal you m..

1. Formulate the cost function in terms of autocorrelation values of the time sequence and filter weights 2. Derive Wiener-Hopf equations (in matrix form) 3. Determine the closed form solution for Wiener-Hopf equations (in matrix form)
A three phase star connected alternator has synchronous impedance of 1+j10ohms per phase. It is operating at a constant voltage of 6.6kV and its field current is adjusted to givean excitation voltage of 6.4kV.
Assume you have a current source connected to a parallel RLC circuit. The current source is i(t)=cos(2t). The Resistor is 2ohms, inductor L=1H, capacitor C=1/2F. compute the average power consumed by this circuit in SSS
a 2.0-kg block is moving right at 1.0 m/s just before it strikes and sticks to a 1.0-kg block iniially at rest. what is the total momentum of the wo blocks after the collision
Ethree-phase, 5 hp, 208 V, 60 Hz induction motor runs at 1746 rpm when it delivers rated output power. (a) Determine the number of poles of the machine. (b) Determine the slip at full load. (c) Determine the frequency of the rotor current.
A measurement system uses an 8-bit A/D converter as output for itssignal in a range of 0 to 10 volts. What is the resolution for this measurement system If a7-bit A/D converter or a 9-bit A/D converter to be used, what is the resolution for the sys..

a boost converter operates at 20 khz, and converts power from a solar panel to a battery bus. the panel has norminal volate of 16v and current up to 3 A. the battery bus is 48 v. the transistor can be modelled as a 0.5 v constant forward drop.
Two rolled-steel channels are to be welded back to back and used to support the loading shown. Knowing that the allowable normal stress for the steel used is 30 ksi, determine the most economical channels that can be used.
The average power is not necessarily equal to the average current times the average voltage. To show this, find a voltage waveform and current waveform where each has a zero average value but their product has a non-zero value.
