Suppose that s(t) is a real-valued signal. We have a set of orthonormal basis functions {ϕi(t)}N i=1 with which we wish to approximate s(t) as s ˆ(t) = N∑ i =1 siϕi(t) such that the energy in the error signal e(t) = s(t) − s ˆ(t) E e = ∫−[infinity] [infinity] e2(t)dt = ∫−[infinity] [infinity] (s(t) − s ˆ(t))2dt is minimized. Calculate the optimum coefficients {si}N i=1 that minimize Ee.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
