2.(20pt) Consider a Wiener process driven stochastic system with an intermittent noisy measurement output: $dx_t = f(x_t)dt + g(x_t)dw_t$ $dy_t = h(x_t)dt + dv_t$, where the measurement $y_t$ is available if and only if $t \in [2k, 2k+1)$ for $k$ nonnegative integers. Describe how the conditional density of $x_t$ evolves over time, conditioning on the past measurement outputs.

Subject: APPLIED NUMERICAL METHODS Question 1 The net force of an airfoil can be resolved into two components: the lift component, which is normal to the freestream velocity vector; and the drag component, which is parallel to the freestream velocity. We can divide the surface into small, elemental areas and resolve the contributions to lift and drag on each area. The net lift is obtained by summing up these elemental contributions (i.e., integrating). Using this approach for a two-dimensional (or infinite span) body, a relatively simple equation for the lift coefficient, C, can be derived using: (C_lower - C_upper) d() = cos(a) ∫Cp dx (1) where α is the angle of attack, c is the body chord length, and the pressure coefficients (Cp) are functions of the normalized length x = x/c. The lower and upper subscript represents the lower and upper surface measurement. Table 1 shows the pressure coefficient, Cp(), obtained from wind tunnel testing (no error) for the angle of attack α: Table 1: Pressure distribution x/c Cpl Cpu 0 0.8 -1 0.05 0.25 1.2 0.1 0 -1.15 0.4 -0.2 -0.8 0.6 -0.1 -0.5 0.8 0 -0.2 1 0.2 0.2 0.5 8 0.5 0.2 1.5 0.2 1.5 Figure 2: Pressure distribution along x/c From the given information: a) Give two differences between interpolation and regression and explain when to use each of the methods. [8 marks] b) Estimate the value of Cpu() from x/c = 0 to 0.4 using an appropriate numerical method. [20 marks] c) Find the value of Cp and Cpu at x/c = 0.2 using the fitting equation found in (b) and calculate the relative error if the exact values at that point are: Cp(0.2) = 0.2 and Cpu(0.2) = 1. Explain whether your choice of method is appropriate for the solution. [5 marks] d) Calculate the coefficient of lift, C, for this airfoil using an appropriate numerical method. [7 marks]

Assume that the Tennessee Valley Power Authority (which is exempt from income taxes) issued $100,000 of 30-year maturity, 10 percent coupon, semiannual payment, tax-exempt bonds on January 1, 2000. The bonds were callable after 10 years, or after January 1, 2012, at a price that is 10 percent above the bonds' par value. On January 1, 2012, the Power Authority learns that it can issue $100,000 of new 20-year, semiannual payment, 8 percent coupon bonds at par. Costs associated with selling the new issue will amount to $2,000. What will be the initial cost of refunding? 10,000 100,000 2,000 12,000
