Description For this part of the assignment, you will create a Grid representing the pacman’s game grid by using a 2D array of Strings as shown in Section 1. Also, you will design the functionality of the pacman as described in Section 2 and represent it in the grid. 1 The Grid The dimensions of the grid is 15 x 15 and the gird is composed of 4 boundaries: north, south, east, and west boundaries as shown in the Figure. The grid has the following characteristics: 1. The boundaries are represented with “X”, and this will block the pacman. 2. There may be obstacles that obstruct the pacman’s movement. 3. There are 4 gates represented with “ ”, and these gates communicates with the opposite gate. E.g., the north gate communicates with the south gate, and the east gate communicates with the west. This means that if the pacman is located in the north gate, next time it moves up will appear in the south gate, similar with the east and west gate. 4. The grid contains cookies represented with “.”. The idea is to collect all the cookies from the grid in order to win the game. Every time the the pacman eats a cookie, the cookie disappears. The Grid has the following fields • grid: is a 2D array of Strings • x-pos: the x-coordinate where the pacman is located • y-pos: the y-coordinate where the pacman is located • counter: a counter that represents the total number of cookies consumed by the pacman In addition, the Grid has the following methods: • initializeGrid(): This method will print a “fresh” new grid with the pacman located in the middle of the grid and the rest of the grid will contain cookies “.”. Except the boundaries of the grid. Your maze shall have four boundaries i.e., north, south, east, and west. The boundaries are represented with an “X”. Each boundary has a gate in the middle that allows the pacman to communicate to the opposite gate. • updateGrid(): will happen after the selection of moving “a”,“s”,“d” or “w” is done. Since these four options will move to west, south, east, or north, then you need to “update” the grid. The way to do this is by passing the x-coordinate and the y-coordinate as arguments to this method. The method then, will update the new position of the pacman (that is, the x and y coordinate from the arguments). Here is where the previous x and y position of the pacman will “disappear” (which is now a blank space “ ”). This method will reflect the new position of the pacman in the grid in case it moved. This method will also reflect the number of cookies consumed. • checkBoundaries(): Before moving the pacman to the new position, this method will check if is possible according the current coordinates. In case is a valid movement, the method will return true. In case the movement is invalid, due to a boundary or through something else, then your method will return false. The Pacman The pacman has the following characteristics: • The pacman has the ability to move through the gates (i.e., north to south, east to west). • The maze is full of cookies (e.g., “.”). The pacman must eat all the cookies to finish the game. Every time the pacman eats a cookie, it disappears from the maze the counter increases by 1. • If pacman movesUp by typing the key w, the pacman’s y-coordinate must increase by one unit. If the pacman’s y-coordinate exceeds the maze’s upper boundary, then the pacman’s y-coordinate AND the maze’s position shall not be updated. • If pacman movesDown by typing the key s, the pacman’s y-coordinate must decrease by one unit. If the pacman’s y-coordinate exceeds the maze’s lower boundary, then the pacman’s y-coordinate AND the maze’s position shall not be updated. • If pacman movesRight, by typing the key d, the pacman’s x-coordinate must increase by one unit. If the pacman’s x-coordinate exceeds the maze’s right boundary, then the pacman’s x-coordinate AND the maze’s position shall not be updated. • If pacman movesLeft, by typing the key a, the pacman’s x-coordinate must decrease by one unit. If the pacman’s x-coordinate exceeds the maze’s left boundary, then the pacman’s x-coordinate AND the maze’s position shall not be updated. Notice that by moving through the y-coordinate the program deals with the rows of the array, similar when dealing with the x-coordinate, the program deals with the columns of array. 3 The Game Engine In order to simulate a game, you must have an engine that keeps looping the position. This is exactly what happens in the old movie theater when they have the 35mm projectors. Here, we will simulate the same idea with a loop: 1. import java.util.Scanner; 2. public class Engine{ 3. public static void main(String [] args){ 4. String[][] grid = new String[10][10]; 5. int col = 5; 6. initializeGrid(grid); 7. grid[5][col] = "P"; 8. Scanner input = new Scanner(System.in); 9. while(true){ 10. print(grid); 11. String option = input.nextLine(); 12. if(option.equals("d")){ 13. // code goes here 14. } 15. // more code goes here 16. } 17. } 18. // methods go here 19. } In Line 4, will create a grid of 10 x 10 of Strings. In Line 7 will store the pacman (’P’) in the middle of the maze. In Line 9 will allow to run your program “forever” until you decide to finish your program. Line 11 will wait for the input from the user to move the pacman (i.e., “a”, “s”, “d”, or “w”). A complete engine can be found in Grid.java.

Part 2:

1. You are investigating the electrical testing circuits and find that, in an inductive circuit, the relationship between instantaneous current i (amps) and the time t (secs) is given by:

i = 2.1(1-e^-9t)

You have been asked to determine the time taken for the current to rise from 1 to 1.5 amps.

Comment on the time taken for the current to rise the same increment from 1.5 to 2 amps and give reasons. You are not required to evaluate this.

2. The drive system of a conveyor used to transport the engine parts is made up of an open belt which passes over two pulleys. The pulleys have diameters of 200mm and 320mm respectively and the distance between centres is 600 mm.

You have been asked to determine the length of the belt, using trigonometric techniques, assuming the belt is in tension.

3. An electrical cable is to be suspended across two machines. The machines are a distance of 4.5 metres apart. The cable takes the shape of a catenary of the form y = c cosh (x/ where x is the horizontal distance of any given point on the catenary from its centre and y is it’s height from the ground surface. You have been asked to determine the fixing point height (y) if the minimum clearance (c) is to be 3m at the centre of the catenary.

I have been given a final year project to develop a model for ‘Spare part inventory control and management’ for multinational company. the model should include the best suitable classification method and a simple mathematical approach for forecasts. Suggest me the best approach to accomplish this. I am expecting,

1. Explanation in developing the model step by step.
2. Suitable classification method for spare parts.
3. A simple mathematical approach for forecasting spare parts (preferably with an example).
4. Other key factors to be concerned in developing the model.
5. Good referencing documents or sites for more accurate information.

Help me to develop the model with a limited time frame due to heavy workload. Thanks

Consider a plane wave of monochromatic green light, ? = 500 nm, that is incident normally upon two identical narrow slits (the widths of the individual slits are much less than ?). The slits are separated by a distance d = 30 µm. An interference pattern is observed on a screen located a distance L away from the slits. On the screen, the location nearest the central maximum where the intensity is zero (i.e., the first dark fringe) is found to be 1.5 cm from this central point. Let this particular position on the screen be referred to as P1.
(a) Calculate the distance, L, to the screen. Show all work.

(b) calculate the ditance between the first and second dark bands in the interference pattern. Shown all work.

(c)In each of the parts below, one change has been made to the problem above (in each case, all parameters not explicitly mentioned have the value or characteristics stated above). For each case, explain briefly whether the light intensity at location P1 would remain zero or not. If not, will P1 become the location of a maximum constructive interference (bright) fringe? In each case, explain your reasoning.

1) One of the two slits is made slightly narrower, so that the amount of light passing through it is less than that through the other.

2) The wavelength is doubled so that ? = 1000 nm.

3) The two slits are replaced by a single slit whose width is exactly 60 µm.

Think about your place of work, your household or your school. Then, come up with 2 examples of efficiency (i.e, what you/they do well) and explain why you consider it efficient, AND 2 examples of inefficiency (i.e, what you/they do NOT do as well as you are capable of) and explain why it is inefficient. For the inefficiency, explain how you would solve each of those problems (correct the inefficiencies). When you reply to others, offer suggestions, input and advice - maybe you experienced something similar.
