Let a bus timetable be represented by a list of routes where each route is repre- sented by Start/End/DepatureTime/ArrivalTime. Both DepartureTime and ArrivalTime are represented by a relation time(Hour,Minutes). Write a Prolog relation journey(Start, End) that is true if there is a route in the timetable that can get a passenger from Startto End directly or any number of intermediate stops where there is at least 10 minutes between the arrival at an intermediate point before the departure of the next leg of the journey. Assume the clock is a 24 hour clock and all departure and arrival times occur within the same day.
Draw a UML Class diagram with the following requirements
"Equatable and Comparable" in the Swift Programming: The Big Nerd Ranch Guide (2nd Ed.) e-book: Point’s current conformance to Comparable yields some confusing results. let c = Point(x: 3, y: 4) let d = Point(x: 2, y: 5) let cGreaterThanD = (c > d) // false let cLessThanD = (c < d) // false let cEqualToD = (c == d) // false As the above example demonstrates, the trouble arises in comparing two points when one point’s x and y properties are not both larger than the other point’s. In actuality, it is not reasonable to compare two points in this manner. Fix this problem by changing Point’s conformance to Comparable. Calculate each point’s Euclidean distance from the origin instead of comparing x and y values. This implementation should return true for a < b when a is closer to the origin than b. Use the formula shown in below Figure 25.1 to calculate a point’s Euclidean distance. Figure 25.1 Euclidean distance Euclidean distance
. Draw the ERD for the following scenario. In a university, a Lecturer can teach many different courses and even the same course numerous times. Courses can also be taught by many lecturers. A student is enrolled in only one program but a program can contain many students. Students can be rolled in many courses at the same time and the courses have many students enrolled.
Define the computer process described below (in bold) as a Finite State Machine in the form A = {S, I, i, δ, F}. What are elements of that set A? Define just all sets including transition functions, no need to draw diagram. Computer can be in On/Off mode, also it can Sleep, Hibernate, run in Full Power, Saving Power, and Balanced modes. Computer must have Power button and Sleep button. Assume that you can put computer into other states by entering some key on a keyboard. After coming back from Off/Sleep/Hibernate, computer enters Balanced run mode.

Any answer that involves a design for a Finite Automaton (DFA) should containinformation about the following five components of the FA (corresponding to the 5-tupledescription):i) The set of states Q; ii) the alphabet Σ; iii) the start state; iv) the set of final states F; v) the set of transitions δ, which can be either shown in the form of a state diagram (preferred) or a transition table. You can either present the answer in the form of a state diagram with all the above information (as shown in the left side of slide #8 in the Finite Automata lecture notes) or in the tabulated form (as shown in the right side of the same slide). State diagram representation is preferred. 1. Give a DFA for each of the following languages defined over the alphabet Σ = {0, 1}: a) L={ w | w contains the substring 101 } b) L={ w | w ends in 001 } c) L={ w | w has a 1 in its 2nd last position, if such a position exists}
The language must be in python. Neural Network Units weights of [-1.2, -1.1, 3.3, -2.1] two training examples:Example 1: [0.9, 10.0, 3.1, 1]Example 2: [0.9, 2.1, 3.7, 1] Note that you don't have to explicitly include a threshold or bias since the examples include a last element of 1 which means that the last weight effectively operates as a threshold. Create a single ReLU unit and provide the outputs for those examples. Calculate the derivative of the sigmoid with respect to net input for both examples Calculate the derivative of the ReLU with respect to net input for both examples
