Consider a binary hypothesis testing where the observation Y has the following PDFs $\qquad f(y|H_0) = \begin{cases} A_0(a - |y|), & \text{for } |y| \le a, \\ 0, & \text{for } |y| > a, \end{cases} \text{ given } H_0,$ $\qquad f(y|H_1) = \begin{cases} A_1(b - |y|), & \text{for } |y| \le b, \\ 0, & \text{for } |y| > b, \end{cases} \text{ given } H_1.$ Let's assume $b > a > 0$. a) Calculate the constants $A_0$ and $A_1$ in terms of parameters $a$ and $b$. b) Assume uniform cost assignment $c_{ij} = 1 - \delta_{ij}$ and find the optimum decision rule based on Bayes criterion. c) Evaluate $P_D$ and $P_{FA}$ as a function of the detection threshold $\Lambda_0 = \frac{\pi_0}{\pi_1}$. Assume $b = 2a$ and sketch the ROC curve.

Write a function named PrintShape that takes an odd positive integer n as an input parameter and prints an n*n square as follows: The first row has the values from n to 1. Each of the next rows rotates the values of its previous row one value to the right such that last value in the previous row becomes first value in the current row. The following are examples for n =7 and n = 5, respectively: 7654321 1765432 2176543 3217654 4321765 5432176 6543217 54321 15432 21543 32154 43215

30 A groundwater supply has the following analysis: calcium = 94 mg/l magnesium = 24 mg/l sodium = 14 mg/l bicarbonate = 317 mg/l sulfate = 67 mg/l chloride = 24 mg/l (a) Calculate the quantities of lime and soda ash for excess-lime softening, and the carbon dioxide reacted for neutralization by two-stage recarbonation. Assume that the practical limits of hardness removal for calcium are 30 mg/l as $CaCO_3$ and for magnesium are 10 mg/l as $CaCO_3$, and that three-quarters of the final alkalinity is converted to bicarbonate. Calcu- late the finished hardness and sketch the bar graphs for the raw and finished waters. (b) Calculate the chemical dosages for split-treatment softening, assuming a permissible magnesium hardness in the finished water of 40 mg/l. Follow the methods of solution in Example 8. Draw the bar graphs, after first-stage lime treatment, of the unreacted combined first-stage effluent and bypassed flow, and the finished water after reaction of soda ash. Cal- culate the finished water hardness.
