In the field of computer networking there is an imprecise relationship between the level of use of a network communication bandwidth and the latency experience in peer-to-peer communication. Let X be a fuzzy set of use levels (in terms of the percentage of full bandwidth used) and Y be a fuzzy set of latencies (in millisecond) with the following membership function: (0.2 0.5 0.8 1.0, 0.6, 0.1) + (10 ' 20 + --+ 40 60 + 80 100) (03 06 09 10 08

- Consider a world on which each individual belongs to a family of six, each family resides in its own home, each house has a specific address and every person in a certain house is given a unique name.Assume that this world has a postal service providing letters from source to destination. The postal service needs (1) the letter to be in an envelope and (2)that the address (and nothing else) of the destination house be clearly shown on the envelope. Suppose each family has a delegated member who receives letters for the other family members and distributes them. The letters do not actually give the receivers of the letters a hint. a. Would the postal service.ever have to open the envelope and inspect the letter and include the service under your protocol?Consider a world on which each individual belongs to a family of six, each family resides in its own home, each house has a specific address and every person in a certain house is given a unique name.

- Let M be the PDA defined by: Q = {90, 91, 92, 93, q4}, Σ = {a, b}, [ = {a, S}, F = {q4} and transition function is defined as below: 8(q0, E, e) = (q1, S) 8(q1, a, e) (q1, a) = 8(q1, E, e) = (q3, ε) 8(q1, b, a) = (q2, ε) 8(q2, b, a) = (q2, ε) 8(q2, &, a) = (q3, &) 8(q3, &, a) = (q3, &) 8(q3, &, $) = (q4, &) 1) draw the state diagram of the PDA. 2) Describe the language accepted by MMessages are sent over a communications channel using two different signals. One signal requires 1 microseconds for transmittal, and the other signal requires 3 microseconds for transmittal. Each signal of a message is followed immediately by the next signal. Using the iterative method (you compute each step by hand) calculate how many different messages can be sent in 6 microseconds? (take the initial conditions of the recurrence relation as: S, = 1 and S, = 1, S, = 1) Seç. Seç. The recurrence relation for "the number of different signals that can be sent in "n" microseconds" is:4. Consider the Railway Reservation System. There are a number of trains and each train stops in one or more stations. Each train has a predetermined number of seats available in each of classes (First class, First AC, Second AC, Third AC, Sleeper and so on). The fare between two stations is determined by the class of travel and the distance. Passenger can enquire about the availability of seats between any two stations and for any class. The Railway Reservation System should be able to handle the queries and perform the necessary reservation/ cancellation operations. Draw a class diagram for the case study.
- Disk I/O: Consider a magnetic disk with N cylinders rotating at a speed of R revolutions per minute. The sector size on the disk is constant. Requests for sectors arriving from the file system can be located anywhere on the disk with equal probability and the locations of the requested sectors are independent of each other. Under these assumptions, on average, over how many disk cylinders will the head have to seek to get from one requested sector to the next? • On average, once the head is positioned over the right cylinder, how long will it take before the head is positioned at the beginning of the right sector? • Say the disk (one platter) has 1000 cylinders and a sector size of 1024 bytes. The transfer time per sector is 0.1 milliseconds (i.e., the raw data rate is 10 Megabytes per second). The rotation speed is 7200 revolutions per minute. The time to seek over X cylinders is given by the formula 5 + X/100 milliseconds. Under the same assumptions above, what will the maximum…In a robotic laboratory of one university, the lab members are testing mobile robots. Each robot has a radio transmitter that it uses to communicate with a base station, and they find that if the robots get too close to one another, then there are problems with interference among the transmitters. So a problem arises: how to plan the motion of the robots in such a way that each robot gets to its intended destination, but in the process the robots don’t come close enough together to cause interference problems. This problem could be modeled as: suppose that we have an undirected graph G=(V,E), representing the floor plan of a building, and there are two robots initially located at nodes a and b in the graph. The robot at node a wants to travel to node c along a path in G, and the robot at node b wants to travel to node d. This is accomplished by means of a schedule: at each time step, the schedule specifies that one of the robots moves across a single edge, from one node to a…Computer Science A way to avoid overfitting in Deep Neural Networks is to add an additional term R to the loss function L (for example L can be the cross entropy loss) as follows: L(w) + λR(w). (1) You know that one choice for R is the L2 norm, i.e. R(w) = ||w||2 2 . One friend of yours from the School of Maths told you however that there’s no need to use squares (i.e. powers of two) and that you can achieve the same effect by using absolute values, i.e. the L1 norm: R(w) = ||w||1. Would you agree with him? i.e. is the use of the L2 norm equivalent to using the L1 norm for regularization purposes? Justify your answer
- Wireless sensor networks are a special kind of network that may transmit data. For data transmission between nodes and the base station, WSNs rely on sensor nodes. The computing resources and storage space of a sensor node are limited. In this thought experiment, we will consider a decomposable algorithm. To solve these subproblems at separate sensor nodes, would you prefer use divide and conquer or dynamic programming? Use succinct language.Assignment Consider the Bayes network below, defined over four Boolean variables X1 X2 X3 Х4 • How many parameters are needed to define P(X1, X2, X3, X4) for this Bayes Net? • Give the formula that calculates P(X1 = 1, X2 = 0, X3 = 1, X4 = 0) using only the Bayes net parameters. Use notation like P(X1= 0|X2 = 1, X4 = 0) to refer to each Bayes net parameter you use in your formula. • Give the formula that calculates P(X1=1,X4=0) using only the Bayes net parameters. • Give the formula that calculates P(X2=1|X3 = 0) using only the Bayes net parameters.AT&T is a telecommunications company with a call centre. When customers call the customer service centre, they are queued up to speak with a customer service representative. Customers are asked to wait and are given a specific number if the operators are busy. A customer's wait time could be as little as a minute or as long as 30 minutes. This also varies according to the type of customer. Platinum customers will receive a higher level of priority than Gold customers. Thus, when a call from a Platinum customer is received, it is prioritised for processing. If there are no remaining Platinum customers in the queue, the Gold customer will be served. Demonstrate the scheduling process of a switch in a phone answering system by using queue. Construct a program to demonstrate the problem. Calculate the average waiting time for each call.
