Compare refined gasoline and diesel in terms of “kW-hr/ liter” units to Li ion battery technology

The higher the wind speed, the quicker a body cools. To quantify this wind speed chilling effect, both the U.S. and Canadian weather services have determined wind chill temperatures for temperatures below 50°F and wind speeds above 4 mph in the United States and temperatures below 10°C and wind speeds above 4.8 km/hr in Canada. An approximation of the official wind chill temperature, for both metric and English units, is given by this formula:

WCI = K1 + 0.6125 Ta - K2Ws0.16 + K3TaWs0.16
The following chart lists the correct dimensions and values for both systems of units:

Using the wind chill formula, write, compile, and run a C++ program that displays a table of wind chill indexes for temperatures from 2°C to 10°C, in 4-degree increments, and for each temperature, wind speeds from 5 km/hr to 11 km/hr in 2-km/hr increments.

Draw the logic diagram for the function f=ΣA,B,C (2, 6, 7) using only AND, OR, and NOT gates.

Then draw logic schematic with only NAND gates, and appropriate resistors/LEDs to have LEDs to show the inputs and the outputs. You will need to swap out your AND, OR, and NOT gates as appropriate. You must show all gates, do not apply the involution theorem in the process. This means you will have more NAND gates than possible to implement with your equipment in this drawing. You will then make note (label) which NAND gates can cancel due to the involution theorem, this will allow you to make sure your circuit can be implemented with your equipment. You do not need to redraw your schematic after you document when you are applying the involution theorem

Diesel Generator A I MVA diesel three-phase generator is rated at 4.16 kV, 60 Hz, and connected as Y its neutral is kept floating. It is directly tied to three loads, one consuming 50% of its capacity, and each of the other two consuming 25% of its capacity. A three-phase to ground fault could occur at any of the loads. Draw a one-line diagram of this system, then describe what type of faults could occur in the generator and diesel engine. Explain at least three types of protection strategies that have to be implemented in such a system, and show necessary fault current calculations. Assume that any fault impedance you may need is 9.02 pu, and any component impedance is 0.4 pu.

Translate the following real world scenario into a signal. Write mathematically. An IV drip is started on a patient of 1000mL saline over 8 hours. At time zero, a linearly increasing drip rate is started for 2 hours. The drip rate is then held constant for 4 hours. The last two hours the drip rate is linearly decreased to zero. Write an analytical expression of the signal in mL/hour.

This is for a signals and systems class. Some basic functions that could be used are u(t) and the delta function.
