  1. Explain fuzzy extension principle with example.
  2. High speed rail monitoring devices sometimes makes use of sensitive sensors to measure the deflection of the earth when the rail car passes. These deflections are measure wrt to some distance from the rail car and hence are actually very low in angle (in microradians). Let a universe of deflection be A={1 2 3 4} where A is the angle of microradians and let the universe of distance be D={1 2 5 7} where D is the distance in feet. The relation S between A & D given as
  D1 D2 D3 D4
A1 1 0.3 0.1 0
A2 0.2 1 0.3 0.1
A3 0 0.7 1 0.2
A4 0 0.1 0.4 1

Now a let a universe of rail car weights be W={1 2} where w is the weight in units of 10000 pounds. Suppose that relation between W & A is given by

  w1 W2
a1 1 0.4
a2 0.5 1
A3 0.3 0.1
A4 0 0

Then find T=Transpose of R o S using Max-min composition, using max-product composition.
