What is ladle analysis and product analysis in steel ? Why it is done and what parameters are tested here ?

Prepare a report for smart building:
● Prepare a building of your own plot area or plinth area.
● Choose environmentally friendly ideas to solve electricity problems of electricity.
(Say if 1 sq m of solar panel produces 100 wt of power, how many solar panels would you need to run the size of the building you are designing?)
● Try to prepare a very comprehensive report as you can.
● Assume a budget and research all the possible rates of objects that you will be using in the smart building and verify if they fall within the budget.
● Choose the location of the building of your choice. As the location of the building changes, material availability, prices and other things change too.

Design a road that goes from Point A to Point B. You cannot cross any water bodies or remove any trees or just 2 trees • When students have finished, pass out the string and rulers and have students measure how long their roads are. Each block(H/V) = 500 meter of roadway(Double lane- 7.5 meter, i.e., 3.5m+3.5m+0.5mdivider), and that every 1 KM of roadway costs CAD 12,500 to build. Calculate and report how much the road costs.
Now you can remove trees, removing each bush(500 m2) costs CAD 14,000(for its lifetime).
If you wish to construct a bridge on the lake, it costs 3 million per 1km of 2 lane bridge.
Propose an alignment of the road such that it is scenic and safe to travel.

What canonical form is used to represent the sequence (x1,x2.....xn) in order to compute the sample mean vector and sample covariance matrix?

Let (x1,x2......xn) be a sequence of vectors
In statistics one often has to compute the sample mean vector
And the sample covariance
My questions are
1.what canonical form of information would I suggest to represent the sequence (x1,x2.......xn)in order to compute the sample mean vector and the sample covariance matrix?
2.How can I verify that all the desirable properties of Canonical information are satisfied:Existence and Uniqueness, Completeness, Elementary, Empty, Combination, Update,and Compactness and Efficiency.
3.What are the minimum number of observations n for which X and V are defined?

A mild steel ring has a mean circumference of 500 mm
and a uniform cross-sectional area of 300 mm2
.
Calculate the m.m.f. required to produce a flux of
500 µWb. An airgap, 1.0 mm in length, is now cut in
the ring. Determine the flux produced if the m.m.f.
remains constant. Assume the relative permeability
of the mild steel to remain constant at 220.

What is the most common method of con- trolling the speed of an alternating-current motor?

Design an XNOR gate with two inputs A and B using only NAND gates .Mention the expression in terms of A and B at the output of each NAND gate in your circuit diagram.

Design and draw voltage regulator to provide 4 to 10 volt variable output voltage using IC 7812.

1)Add the following in binary.a.1011 + 1010b.1111 + 0011
2)Add the following numbers using 2’s complement to represent the numbers. Use a bit length of 8 bits.a.20 + 10b.-10 + 20
3)What is the largest negative 8 bit, 2’s complement number? What is the largest positive 8 bit, 2’s complement number?
4)A – B = A + (-B). Therefore subtraction can be done with addition if the sign of B is changed. Using 8 bit, 2’s complement addition, perform the following operations.a.24 + (-14)b.-24 + (-14)
5)What is the decimal value of 11111111111111111111111111111101 if the number is in 2’s complement.
6)Use a 2-to-4 decoder and one OR gate (for the sum) to create a half adder.
7)Use a 3-to-8 decoder and two OR gates (one for sum and one for carry) to create a full add
