4. Consider the Railway Reservation System. There are a number of trains and each train stopsin one or more stations. Each train has a predetermined number of seats available in each ofclasses (First class, First AC, Second AC, Third AC, Sleeper and so on). The fare betweentwo stations is determined by the class of travel and the distance. Passenger can enquireabout the availability of seats between any two stations and for any class. The RailwayReservation System should be able to handle the queries and perform the necessaryreservation/ cancellation operations. Draw a class diagram for the case study.

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 AI 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 dirccted to the correct storage bin. As a startup case, the simple network will only be used for two types of fruit i.e. banana and apple.…

A medical Centre can have many doctors. A doctor can be scheduled for many appointments but may not have any scheduled appointment at all. A patient can schedule request for one or more appointments. However, every appointment is about only one patient. As a result of every appointment, there must be a bill. One payment is applied to exactly 1 bill, and 1 bill can be paid off over time by several payments. A bill can be outstanding, having nothing yet paid on it at all. One patient can make many payments, but a single payment is made by only 1 patient. Some patients are insured by an insurance company. If they are insured, they can only carry insurance with one company. An insurance company can have many patients carry their policies. For patients that carry insurance, the insurance company will make payments, each single payment is made by exactly 1 insurance company. (Hint: final ERD must include 7 tables.) a) Identify the entities with attributes and keys (primary and foreign keys).…

imagine that as example We have a transportation company operates individual taxis and shuttles. It uses its taxis for transporting in the form of an individual or small group from one location to another. On the other hand, the shuttles have different scenario. They are used to pick up individuals from separate locations and provide them conveyance to several destinations. Any individual can call the company from anywhere. It may be a hotel, a mall, entertainment venue or any tourist company. When the company receives a call from such individuals, it tries schedule any available taxi for pickup service for fee-based If There's no available taxi, it does not operate any form of queuing system. Means " If there is no available car, the order is lost " If the vehicles are available, the individual confirms for pick-up. After arrival at the pick-up place the driver notify the company that it has picked up the passenger. The driver notifies the company again at the time of dropping him…
A detective has interviewed four witnesses to a crime. From the stories of the witnesses the detective has concluded that: If the handyman is lying, then so is the butler. The gardener and the handyman cannot both be telling the truth. The cook and the gardener are not both lying. The handyman is telling the truth only if the cook is lying. For each of the four witnesses, can the detective determine whether that person is telling the truth or lying? Use the truth table to explain your reasoning (Give the full truth table). Please use the following notations in your reasoning – B: The butler is telling the truth. C: The cooking is telling the truth. G: The gardener is telling the truth. H: The handyman is telling the truth.

Can you help me write the code for this MATLAB assignment?
After college, a group of students of a certain height planned to go to the movies. The cinema they go to is quite unique because the number of cinema rows is always 2 and the number of seats is as many as the number of students. Because this is a unique cinema, the way they sit is also unique. They will try to minimize their height difference with the one next to it so that the biggest height difference of each pair of students next to each other is as minimal as possible. Example: There are 6 students with height of 1, 6, 9, 7, 2, and 3. There are various sequences that can produce the biggest difference in height. Ordering 1:1 3 62 7 9Difference 1 and 3 is 2.Difference 3 and 6 is 3.Difference 2 and 7 is 5.Difference 7 and 9 is 2.So the biggest difference in height is 5. Ordering 2:1 3 26 7 9The biggest difference in height is 2.This difference is also an optimal answer. Format Input : There are T test cases. Each testcase contains integers N which indicates the number of students…
