ENGINEERING The capacitance of two parallel conductors of length L and radius r, separated by a distance d in air, is given by $$ C = \frac { \pi \epsilon L } { \ln [ ( d - r ) / r ] } $$ where $\epsilon$ is the permittitivity of air ($\epsilon = 8.854 \times 10^{-12} \text{F/m}$). Create a cell array of capacitance values versus d, L, and r for d = 0.003, 0.004, 0.005, and 0.01 m; L = 1, 2, 3 m; and r = 0.001, 0.002, 0.003 m. Use MATLAB to determine the capacitance value for d = 0.005, L = 2, and r = 0.001. Verified answer Recommended textbook solutions

COMPUTER SCIENCE The join operation takes two dynamic sets $$ S_1 $$ and $$ S_2 $$ and an element x such that for any $$ x_1 ∈ S_1 $$ and $$ x_2 ∈ S_2 $$ , we have $$ x_1.key ≤ x.key ≤ x_2.key $$ . It returns a set $$ S = S_1 ∪ [x] ∪ S_2 $$ . In this problem, we investigate how to implement the join operation on red-black trees. a. Given a red-black tree T , let us store its black-height as the new attribute T.bh. Argue that RB-INSERT and RB-DELETE can maintain the bh attribute without requiring extra storage in the nodes of the tree and without increasing the asymptotic running times. Show that while descending through T , we can determine the black-height of each node we visit in O(1) time per node visited. We wish to implement the operation RB-JOIN $$ (T_1, x, T_2) $$ , which destroys $$ T_1 $$ and $$ T_2 $$ and returns a red-black tree $$ T = T_1 ∪ \{x\} ∪ T_2 $$ . Let n be the total number of nodes in $$ T_1 $$ and $$ T_2 $$ . b. Assume that $$ T_1.bh ≥ T_2.bh $$ . Describe an O(lg n)-time algorithm that finds a black node y in $$ T_1 $$ with the largest key from among those nodes whose black height is $$ T_2.bh $$ . c. Let $$ T_y $$ be the subtree rooted at y. Describe how $$ T_y ∪ [x] ∪ T_2 $$ can replace $$ T_y $$ in O(1) time without destroying the binary-search-tree property d. What color should we make x so that red-black properties 1, 3, and 5 are maintained? Describe how to enforce properties 2 and 4 in O(lg n) time. e. Argue that no generality is lost by making the assumption in part (b). Describe the symmetric situation that arises when $$ T_1.bh ≤ T_2.bh $$ . f. Argue that the running time of RB-JOIN is O(lg n).

COMPUTER SCIENCE For this assignment, you will write a program that lets the user play against the computer in a variation of the popular blackjack card game. In this variation of the game, two six-sided dice are used instead of cards. The dice are rolled, and the player tries to beat the computer’s hidden total without going over 21. Here are some suggestions for the game’s design: - Each round of the game is performed as an iteration of a loop that repeats as long as the player agrees to roll the dice, and the player’s total does not exceed 21. - At the beginning of each round, the program will ask the users whether they want to roll the dice to accumulate points. - During each round, the program simulates the rolling of two six-sided dice. It rolls the dice first for the computer, and then it asks the user if he or she wants to roll. (Use the Die class that was demonstrated in this chapter to simulate the dice). - The loop keeps a running total of both the computer and the user’s points. - The computer’s total should remain hidden until the loop has finished. - After the loop has finished, the computer’s total is revealed, and the player with the most points without going over 21 wins.
