Browser Requirements The latest releases for any of these: Chrome, Edge, Firefox and Safari. Mobile Device Requirements Assume a device that has been release in the past 2 years. High-level Requirements 1. The student can host their project on a free public hosting service or on localhost. There will be a loss of 10 points from the overal grade if the student simply uses the le:// protocol. 2. Students should develop/design their work to be a mobile rst design, then desktop with media queries and/or responsive design patterns 3. There shouldn’t be any in the browser console. The point loss you receieve on this point depends on the number or errors in the console. 4. Must use CSS extensively. Do not use HTML tables to structure your website’s pages. If you do, you will lose 10 points immediately upon grading. 5. You cannot cut and paste the same CSS rules over and over again in each HTML page to meet the minimum number of selectors used. (See CSS requirements) 6. Should not copy javascript from other sources and say you did it. You can learn from them. Integrate with them, but do not simply take their work, put into your page and say you developed it. 7. You do not need to have a database, but you can use one if you want. That’s completely optional and up to you. We don’t have any points to give for your extra effort on creating or using a database. However, it is GOOD experience and you should try if you have time. 8. The minimum HTML pages you need to have: 1 (one). That is the bare mimimum for a SPA webapp. However, you need to have or show a complete website with content and purpose. In general, you should not need to create more than 10 views/pages. (Having a high page count does not mean a good grade) CSS Requirements a. Must use at least 10 descendent selectors. b. Must use at least 10 unique adjacent selectors. c. Must have 2+ different class selectors. d. Must have at least 2 ID selectors. e. Must have 5 or more pseudo element selectors. f. Must have 5 or more pseudo class selectors Javascript Requirements a. Use of React, Vue or Angular is ne. But, you do not have to use these frameworks.i. Javascript code should use ES6 modules. You don’t have to – but you should. ii. You must have at least 20 active event handlers. They can be of any type. (click, select, drop/drag, mouse events, window events). iii. Must have at least one functional and in-use ES6 class in your active codebase. Meaning, you can just declare a ES6 class and not use it. iv. Global functions are generally not a good idea. If you need to declare a Globally- scoped function, you need to put in a comment on top of it explaining why. Please use Javascrit Modules instead.v. You need to show prociency using functions. Do not simply cut paste the same functions over and over again. Your functions should be unique and do something useful to your web application.Since you will have at least 20 active event handlers from the previous requirement, you should have enough coded to meet this requirement. But, you need to show a mix of: Function Expressions Function Declarations Arrow Functionsb. The website must use Ajax in some way. The minimum number of Ajax calls in your pages/views are 4 CRUD operations actively used. (You can use Axios, Fetch or native XHR)Optional Requirements 1. Students can use ReactJS, Vue or Angular if they choose to. 2. Students can create a backend system with NodeJS, PHP, Java, etc.. It is not required. 3. Students can choose to develop their website as a SPA (Single Page Application) 4. Students can use any open source component. However, student must show their own work and Javascript abilities and not rely on using open-source for the entirely of their project. 5. Students can develop a database. It is not required

Watch video Indexes In SQL Server1. Run the script file “Create database 1.sql”, this will create the database Index_Examples and two tables, dbo.raw_data, dbo.index_example. & it will insert 2000 rows of data into dbo.raw_data. Next run the script Script File for Index Assignment.sql”. It will insert 4,000,000 rows into the dbo.index_example table (id, first_name, last_name, birthday). If I created a database with more it will bog down your CPU. With 4 million rows, you will see the difference in time between a non-index query and an index query. You are looking for the SQL Server Execution Time.2. Run the following queries separately and record the time it took to complete each (see attached document “Example of Solution of Index Assignment.pdf”). You will have to set up the query window to show statistics & time. Go to the pull down menu Query, click on Query Options, under Execution, Advance check the box SET STATISTICS TIME, click OK.

1. Ask the user for ten (10) grades, and store the data in an array. Compute the average of all the grades. Print the original ten grades and the average.a. Declare an integer array with the name of “grades” of size 10 in the main functionb. Create a function called “getGrades” that prompts the User for the grades and puts them in an integer array.i. The function will receive an integer array and the size of the array.ii. In the function prototype and the function header, call the array “gradeArray” and call the size of the array “size.”iii. Create a For Loop that cycles through each cell of the array.iv. At each cell prompt the User for a grade.v. Store the grade entered by the User into the array cell.c. From main, send this function the array called “grades” and the size of the array.d. Create a function called “computeAverage” that computes the average of an array of integers and returns the average as a float.i. The function will receive an integer array and the size of the array.ii. In the function prototype and the function header, call the array “numbers” and call the size of the array “size.”iii. Create a For Loop that cycles through each cell of the array and computes a running total of the values stored in the array.iv. Use the size of the array to compute the average from the running total.v. Return the average through the function name.e. From main, send this function the array called “grades” and the size of the array.f. From main, print out the average returned by computeAverage.g. Create a third function called “printInts” that will print out the contents of an integer array. This function will be void.i. The function will receive an integer array and the size of the array.ii. In the function prototype and the function header, call the array “intArray” and call the size of the array “size.”iii. Create a For Loop that prints out the contents of the array.2. Generate 20 random numbers within a range of 1 to 50 and store them in an integer array named “randomArray.” Then print out the contents of the array.a. Create a function named “getRandom” that will generate a random number between any range.i. The function will receive two call-by-value arguments – the beginning value of the range and the ending value of the range.ii. Generate a random number within the specified range.iii. Send the random number back through the function name.b. In the main function, create a For Loop that cycles through the array called randomArray.i. With each cycle, call your getRandom function from main and store the random number it returns into your array.c. In main, call the function printInts to print out the contents of the array called randomArray. Make sure you use the SAME FUNCTION you created in step 1. You are just sending it a different array.d. Next, in the main function, call the function computeAverage to compute the average of the random numbers you stored in the array called randomArray. Make sure you use the SAME FUNCTION you created in step 1. You are just sending it a different array.e. In main, print out the average returned by computeAverage.

Data StructuresProgram Assignment #4Sorting AlgorithmsFocus on Sorting Algorithms and Object-oriented programmingTask :Write a class, namely sorting, that contains at least seven functions: (1) constructor that initializes all the data members if any; (2)start function that reads the data size and maximum number in the list from the keyboard, then generates data set, then call a proper function to sort; (3) selection sort function that carries out a selection sort and counts how many comparisons and moves; (4) insertion sort that conducts an insertion sort and counts how many comparisons and moves; (5) quick sort function that does a quick sort and counts how many comparisons and moves; (6) merge sort function that performs a merge sort and counts how many comparisons and moves; and (7) print function that prints the first 15 elements of the sorted list and the sorting results.REQUIREMENTS:1. You must have a program design file you may suffer 10 % percent penalty if you failed to do so.2. You must have a readme file that instructs readers how to compile and run your program you may suffer 10 % percent penalty if you failed to do so.3. You must comment your program properly (including proper comments and program synopsis.) you may suffer 10 % percent penalty if you failed to do so.4. You must put your functions and variables together to form a class—Sorter.5. You must turn on a copy of the output of your program6. A late project will NOT be accepted and No exceptions.Design :You use the general random number generator to produce a set of random numbers, and then make enough copies for your sorting algorithms. Then sends a copy of the list to each of sorting algorithms. Finally, each algorithm produces a sorting report.Input:Your program needs two integers from keyboard: the size of list and maximum number in your list.Output:The first 20 elements in the sorted list, # of comparisons from each sorting algorithm

This Assignment is an implementation of a small simulation program. It is a simulation of a process scheduler of a computer system. This simulated scheduler is a very small, simplified version, which reflects some of the basic operations of a typical process scheduler.To successfully finish the program, you are expected to:know how to define and use a user-defined comparatorknowhow to use Java’s PriorityQueue.know how to write a small simulation program.

1. Data evaluation and elementary preprocessing. Analyse completeness of data. Are there missedata (besides weekends)? How many missed data points are in your time series? Are the dates ofmissed values the same for all your time series? What may be the reasons for missing? How can youhandle the missed values in your data (explain at least three approaches)? Use the simple rule: fill in amissed value by the closest in time past existing value. Plot the results. Normalise to the z-score (zeromean and unit standard deviation). Plot the results. (15 marks)3. Segmentation. Prepare the bottom-up piecewise linear segmentation for the transformed andnormalised log-return time series. Use the following mean square errors tolerance levels: 1%, 5%, 10%(the thresholds of the mean square errors). Plot the results. Are the segments similar for different timeseries you analysed? (25 marks)
