Problem Score 3 5 Total Problem 3 NASA is awaiting construction of an essential component that must be assembled in (in months) required for stage k (where (i.e., they are independently identically distributed) The total time (T) to construct the component is therefore one stage to the other with no time delay). (a) Find the value of the probability density function of the actual mathematical function at t=8 and this without finding the entire pdf fT 1 ting construction of an essential component that must be assembled in two (where k = 1 or 2) is described by the random variable X , they are independently identically distributed) to construct the component is therefore T =X1 X2 (i.e., the component is passed from one stage to the other with no time delay). of the probability density function fT(t) @ t=8 (i.e., find fT(8)) (NOTE: This is the of the actual mathematical function at t=8 and not a probability of any kind. You should be able to find T(t).) (5 points) two stages. The time is described by the random variable Xk shown below (i.e., the component is passed from (8)) (NOTE: This is the value a probability of any kind. You should be able to find
In fourier transforms, what does the characteristic of conjugate symmetry imply graphically: i.e. if x(t) = x*(t) then X(omega) = X*(-omega) Can you explain his graphically? likewise: if x(t) = x*(-t) then X(omega) = X*(omega) What does conjugate symmetry and conjugate assymetry mean? Thanks – Gregg

A mass of 2.5kg are hung vertically from a spring of stifness 5.4kN/m, calculate the maximum amplitude of vibration if the mass is not to jump off the hook. I have detrmined the period is T=0.135s, f=7.4Hz and Theta =46.48 rads/s, but i just cant find a formula for amplitude without the displacement, so i’m not sure how to work out the amplitude.
A 3 by 4 m side of an open tank is hinged at its bottom A and is held in place by a thin rod BC.
What are the three most common packet sizes in the Internet? Explain why this is the case
Consider a stable nocturnal boudary layer in a 12 hr night. The wind is blowing at 5 m/s and the surface is cooled with a kinematic heat flux of -0.02 K.m/s. The residual layer potential temperature is theta=25 degree centigrade. a) what is the potential temperature profile at the end of the night? b) plot the evolution of the height, h, of the stable boundary layer and the strength, delta thetas, as a function of time.
Given an early morning sounding with surface temperature 5 degree centigrade, find the mixed-layer potential temperature and depth at 11 A.M., when the cumulative heating is 800K.m. Assume the early temperature profile is a. delta theta / delta Z= 2 K/km=constant b. delat theta(z)= (8 degree centigrade.exp(-z/150m)
A generator bus (with a 1.0 per unit voltage) supplies a 150 MW, 50 Mvar load through a lossless transmission line with per unit (100 MVA base) impedance of j0.1 and no line charging. Starting with an initial voltage guess of 1.0 with 0degrees, iterate until converged using the Newton-Raphson power flow method. For convergence criteria use a maximum power flow mismatch of 1 MVA
