Consider a code segment with a ring bracket of <2, 2, 4>. needs to interact with a code segment , but has a lesser trust level than . So we want to only make controlled calls to procedure through a gate. Pick the most appropriate ring bracket for among the options below. Both segments and belong to the same user process.

Wireless sensor networks (WSNs) refer to a domain of communication networks. In a WSN, small devices called sensor nodes are used for data transfer among each other and a base station. One limitation of a sensor node is that it has a very limited processing capability and very small memory. Consider a scenario in which you have an algorithm that can be subdivided into smaller problems. If you have to run these sub-problems in different sensor nodes, would you prefer to use divide & conquer approach or dynamic programming approach? Write briefly and precisely.

Implement Thirsty problem using semaphore. Write the code in C/C++ Scenario: To drink, a thirsty person must have three things; water, ice and a glass. There are three thirsty people, each having a different one (and only one) of the three required items. A fourth person, a server has unlimited supply of all three items. If nobody is drinking, the server places two of the three items (chosen at random) onto table. Thirsty person who can make a drink from those two items will pick them up and drink a glass of ice water. When done, thirsty person will notify the server and the process will repeat.

In programming, we use the mask concept to indicate information that can be shown to the user and information that must be “masked”, that is, hidden. In an implementation of a hangman game, we use a mask to indicate which secret word positions the player has already guessed right (whose the contents must therefore be shown to the player), and which positions must remain hidden. Each time that the player hits a letter of the hidden word, the mask is updated so that it has little dashes in the places of letters that the player has not hit yet and show it, in their proper place, the letters that he already hit it. For example, if the word is "cards", the current mask is: - a - - s and the player guesses the letter "d", the mask should be updated to: - a - ds.Write a function called update_mask that takes as input a string containing the word secret (in the example above, this word would be “cards”), a list whose elements are the characters of the current mask (in the example above…

The register we discussed in class has two inputs, D and clock, and one output, Q. If you are interested, you can access a simulator of this circuit at http://www.falstad.com/circuit/e-edgedff.html (note that that simulator has an extra output, !Q, below Q). If D is 1 as clock transitions from 0 to 1, which of the following is true? A. Q is (or soon becomes) 0 B. Q is (or soon becomes) 1 C. Q oscillates between 0 and 1 D. Q holds a steady value, which could be 0 or 1

Let's revisit our first problem, where we want to set up a series of chess matches so we can rank six players in our class. As we did before, we will assume that everyone keeps their chess rating a private secret; however, when two players have a chess match, the person with the higher rating wins 100% of the time. But this time, we are only interested in identifying the BEST of these six players and the WORST of these six players. (We don't care about the relative ordering or ranking of the middle four players.) Your goal is to devise a comparison-based algorithm that is guaranteed to identify the player with the highest rating and the player with the lowest rating. Because you are very strong at Algorithm Design, you know how to do this in the most efficient way. Here are five statements. A. There exists an algorithm to solve this problem using 6 matches, but there does not exist an algorithm using only 5 matches. B. There exists an algorithm to solve this problem using 7 matches,…

Implement the function integrate_3(func, xa, xb, ya, yb, za, zb). xa and xb are the endpoints in the x-axis. ya and yb are the endpoints in the y-axis. za and zb are the endpoints in the z-axis. For example, if we have   def h(x, y, z): returnmath.sin(x)+math.cos(y)+math.tan(z)   r = integrate_3(h, 0, 3, 0, 2, 0, 1) print("{:.3f}".format(r)) This should print 10.453. Set Δx, Δy, and Δz equal to 0.01. The code above corresponds to the following: (see the attached picture below)   The functions should return values, NOT print them. Use python, only import math library nothing else.

A produce dealer has a warehouse that stores a variety of fruits. He wants a machine capable of sorting the fruit according to the type. There is a conveyor belt on which the fruit is loaded. It is then passed through a set of sensors which measure 3 properties of the fruit: shape, texture, and weight. The sensor system is somehow rather primitive: • Shape sensor :-1 if the fruit is round and 1 if it is more elliptical • Texture sensor :-1 if the surface is smooth, 1 if it is rough • Weight sensor :-1 if the fruit is > 500g, 1 if is < 500g The sensor output will then be input to a Neural Networks based classifying system. As an Al Engineer you are supposed to design (draw the architecture and determine the optimal weight W and bias b) a simple neural network (could be a single perceptron) that can be used to recognize the fruit so that it can be directed to the correct storage bin. As a startup case, the simple network will only be used for two type of fruit i.e. banana and apple.…
