Running head: SYSTEM PROPOSAL 1 System Proposal on Roommate Student’s Name Institutional Affiliation SYSTEM PROPOSAL 2 System Proposal on Roommate 1.0 Introduction The document provides an analytical report on building an app called Roommate that will aid students in search of rooms, and it has a provision for posting any possible available rooms. Part one entails planning phase in which it comprises of feasibility study system request and defining requirements while the second part includes a demonstration of the system application that focuses on the use-case, all activities, initial class, and descriptions alongside sequence diagrams. The third part of the project is the design phase in which it contains database design elements, package diagrams, manipulation design, and data access. Planning Phase 1.1 Problem domain statement Many students daily move to different cities and states to achieve their higher education and pursue their dream. As a struggling student, there are already several expenses that one has to cover in which rent is also one of them. As the prices of attending college are rising higher than ever, the new startup company “Nimbous,” strive to help ease the burden of debt on college students. Nimbous wants to create an app called Roommate. Roommate’s goal is to build a network system where students can find room to live at a lower cost, and if students have space to spare, they can also share it with other students to reduce their cost of li ...

Davenport University Create a Sample Image Image Processing Task

First thing we’re going to do is learn how to create a sample image that will be useful for this lab. We will do this by using the Matlab command ‘checkerboard’.To give you an idea on how this command works, from the matlab command prompt, type the following:imshow(checkerboard(20));It should create the image shown below: (see fig1.png)The 20 in the command is the number of pixels that each box on the checkerboard will represent.Let’s create an image from this matrix that we can use later. In order to do that, we need to use the ‘imwrite’ command.imwrite(checkerboard(20), ‘checkerboard.jpg’, ‘JPEG’);To verify the above worked correctly, let’s read in the newly made image and display it:myImage = imread(‘checkerboard.jpg’);imshow(myImage); Now that we have a nice image to use for our edge detection algorithm, let’s begin to implement it. First thing we want to do is create our x and y gradient filters:Sx = [1 0 -1; 2 0 -2; 1 0 -1];Sy = [1 2 1; 0 0 0; -1 -2 -1];Convolve each of the above filters with the checkerboard image. Before we are able to use the convolve function we must convert our image into a double. We do that by using the ‘double’ command and passing it image variable name, in this case ‘myImage’.sobelXImage = conv2(double(myImage), Sx, 'same');sobelYImage = conv2(double(myImage), Sy, 'same');Let’s go ahead and take a peek at what our images currently look like:figure('Name', 'X gradient');imshow(uint8(sobelXImage));figure('Name', 'Y gradient');imshow(uint8(sobelYImage));Do the gradient images look like you expect them too? Why or why not?What is missing from the above question and how would you fix it?Now that we understand what the gradients are doing and are able to display them properly, let’s continue on with our edge detection. We now need to square each of the X and Y portions, and then take the square root of them to determine the magnitude of our gradients.E(u,v) = sqrt( (Dx(u,v))2 + (Dy(u,v))2 )Enter the appropriate matlab command for the above formula and display the image. You should see something like fig.pngEach of the edges are shown in white.Part BDownload a sample image from the net. Repeat the above steps and display the original image, the X gradient, and the Y gradient on one form/figure (Note: Don’t forget to convert it to black and white first) .After we sum the squares and take the square root we have the magnitude of our edge strength. We may not want to look at every single edge detected. We can limit which edges we want to see by applying a threshold. We can do this by using the following matlab commands:threshold = 50;edgeDetectedImage = (uint8(edgeDetectedImage) > threshold) * 255;Create 4 additional figures each with their own respective image on it (using threshold {50, 100, 150, 200} ). Make sure the titles of the figures reflect their contents.Turn in the final matlab script that you used to accomplish part B. It should display 5 figures

create tables in database - java/ MySQL

Assignment InstructionsComplete the following steps for this assignment:Create a MySQL script that creates the tables in the database with the appropriate primary and foreign keys.Your script must add data into the database tables. Every table must be loaded with at least two rows of data.Create screen captures showing the creation and contents of each table.Check and implement the database connectivity using JDBC.Check and implement exception handling for the database connectivity.Implement the Log-in action in your CapestraApp project, checking for the specified username and pass-word in the database and reporting a successful or unsuccessful log-in.Run your CapestraApp program and do screen captures of both successful and unsuccessful log-in attempts.Do not capture your entire desktop—just capture the individual screens.Paste all screen shots into a single MS Word document.Your name should appear at the top of the MS Word document.Name your document, following this pattern: LastName_Week5.docx.Create a .zip file containing your MySQL script file, your MS Word document, and a .zip of your CapestraApp project.Rename your .zip file, following this pattern: LastName_Week5.zip.SQL: CREATE ALL TABLES IN DATABASE; LOAD DATA INTO DATABASEOverviewTo integrate the functionality between the database and the application, you need to create the connection using JDBC. The JDBC API allows Java to connect to MySQL 5.7 using the MySQL Driver on any platform. The JDBC API allows Java to connect to the database, create and execute queries, and view and modify resulting records. Be sure to view the videos to guide you through the database creation and connection. You will need to create a MySQL script to create the ‘orderentrysystem’ database used by the CapestraApp application. The script must not only create all appropriate tables but also must load some sample data into each table. Note that just creating the database within MySQL Workbench does not satisfy the requirements of this assignment—you must create the database using a MySQL script file.This week’s assignment also includes a small programming assignment: You will create the semantics behind your revised Log-in scene. Currently your Log-in scene only provides the employee with a field for entering a username. Checking the SRS, you will see that the Log-in scene must provide for both a username and a pass-word. A successful log-in takes place only if both are provided to the system and they match what is in the orderentrysystem Employee table. You need to modify the Log-in scene to provide for a correctly functioning pass-word field, as well as using MySQL to determine whether the username-passwor-d combination matches an employee in the database. If a match is found, an appropriate message (including the employee's first name, last name, and employee ID) should be displayed to the user. If no match is found, an appropriate message should be displayed.In this assignment, you will create the database tables in MySQL 5.7 for the CapestraApp application. In addition, you will create and check the functionality to connect to the database from the application through a connector using JDBC. Use CapestraApp code provided to check that the database connection is correctly implemented. You need to ensure that exception handling is done correctly in case the database does not exist or if the connection fails.Check the SRS to see precisely what the Log-in action must do. Examine what is implemented in the CapestraApp template code to see what it does and how it does it. You’ll need to think about how to modify the existing code to meet the SRS requirements.
