HW7_3 Ball bearings are hardened through a process known as quenching-submersion of the heated ball bearing in oil or water in order to cool it rapidly. The data below represent the temperature of the ball at various points in the cooling process time (sec) 0 30 Temp (C) 800 457 269 79 46 60 150 240 Plot the data (as discrete points). In the same figure window, also plot a) interpolating polynomial, (use polyfit and polyval) b) piecewise cubic interpolation (not-a-knot) and c) piecewise cubic interpolation (shape-preserving) Include a legend for the three methods used: polynomial interpolation, not-a-knot, shape-preserving. Then looking at the plot, choose the method you believe to be the best and smoothest fit of all these to predict the temperature after 3 minutes of cooling. Print the result using fprintf.
The file london_weather.csv contains weather data for the years 1979 to 2020. The first five lines of this file are: date,cloud_cover,sunshine,global_radiation,max_temp,mean_temp,min_temp,precipitation,pressure,snow_depth19790101,2,7,52,2.3,-4.1,-7.5,0.4,101900,919790102,6,1.7,27,1.6,-2.6,-7.5,0,102530,819790103,5,0,13,1.3,-2.8,-7.2,0,102050,419790104,8,0,13,-0.3,-2.6,-6.5,0,100840,2 Note, in particular, that the dates are given as eight-digit integers in the format YYYYMMDD. There appears to be some inconsistencies in this data, as there are rows for which the column max_temp contains an entry that is smaller than the corresponding entry in min_temp. Write a Python function wrong_temperature(year) that returns the number of days in a given year for which the column max_temp contains an entry that is smaller than the corresponding entry in the column min_temp.
Write a program (call it chr21_gene_names.py) that asks the user to enter a gene symbol and then prints the description for that gene based on data from the chr21_genes.txt file. The program should give an error message if the entered symbol is not found in the table (the user should should not have to worry about case, i.e. it will be a case-insensitive search). The program should continue to ask the user for genes until "quit" or "exit" is given (case-insensitive). Make sure to prompt the user to enter the quit to end the program. Use Dictionaries to solve this problem.HINT: Feel free to use as Dictionary of Dictionaries, but it is not required. HINT: First read the entire text file into a Dictionary that maps the association between gene symbol and description. Once again, make sure to use a Dictionary. Remember to have these command line options: $ python3 chr21_gene_names.py -h usage: chr21_gene_names.py [-h] -i INFILE Open chr21_genes.txt, and ask user for a gene name optional…

The following is a preview of the DataFrames df_1. Which of the following statement(s) are true? df_1 date temperature humidity 2018/01/01 70 85 2018/01/02 68 80 2018/01/03 71 80 df_1 is in long format because each row represents an observation and each column represents a variable. df_1 is in wide format, i.e, each row is 1 record of an observation and each column represents a feature about a record. A dataframe cannot be seen as a table.
Q. Write a trigger that checks the length of a contract when a new contract is inserted into longtermcontract table. If this is the first contract between the pharmacy and pharmaceutical company, the length of the contract should not be more than 12 months. If the contract is more than 12 months, the trigger should alter the end date and reduce it to 12 months after the start date. * You have to use BEFORE INSERT ON* THE INSERT STATEMENT IN THE END OF THE GIVEN CODE MUST WORK.

In java create an application to manage your data base information the database is already created in mysql tables, the tables are fill, So the user can use your database application user friendly Retrieve all data: Given a table name, retrieve all data from the table and present it to the user. Average: Given a table name and a column name, return the average of the column. Here the assumption is that the column type will be numeric (e.g., cost column). Insert: Given a table name, your program should show the column names of that table and ask the users to input new data to the table. In case of errors, your program should directly show the MySQL errors to the users. Assumption 1: Users will enter data according to the database constraints. Assumption 2: Users will input one record at a time. Delete: Given a table name, your program should show the column names of that table and ask the users to input data that they want to delete. Assumption 1: Users will enter data according to the…
The file transactions.txt contains rows of transactions. Each transaction (row) consists of a start month,end month and name. Each of these three values is a String.In the following tasks you are asked to read and store the transactions from the file and determine if thereare any duplicate transactions. A transaction is a duplicate if all three values are the same as the threevalues of any other transaction.a. add code to your main method that reads the content of transactions.txt and stores itin a two-dimensional String array. The name of the String array is your choice. Note that you maynot assume that the number of rows in transactions.txt will always be the same. However, youmay assume that there will always be three String values on a single row. The first dimension of yourtwo-dimensional array must be resized dynamically each time a new record is read (Hint: we did thisin class with a single dimensional array and this is very, very similar). Your code will be evaluatedwith rows…
Complete the move_dollar_to_the_left(coins_list, position_number, to_move) function. This function takes three parameters (the coins list, the position of the "$" symbol to be moved and the number of positions to move). Firstly, work out the new position for the "$" symbol being moved (always moving to the left). The function replaces the "$" symbol in the position given by the parameter, position_number, '$'] and the position number to with a "-" symbol, and moves a "$" symbol into the new position in the list. For example, if the coins list is ['$', '-', '$', '-', '$', move the coin from is 9 (the last position in the list) and the number of places to move is 3, the function should modify the list to: "['$', '$', '$', '-']. Note: • The position number is a number starting from 1, therefore referring to the "$" symbol in position 9 is referring to the "$" symbol at index 8 of the parameter list. • The function makes changes in place. (i.e. it changes the list that is passed to the…
SQL A table Products have: a name (TEXT) a description (TEXT) a unit cost stored in cents (INTEGER) and of course we also add an id column to identify them. Separately, we'd like to track the number of items in stock for each product. To do so we'll have a store and an inventory table. Stores have just an id and a name. Then, our inventory table should combine stores and products, listing how much of each product each store has in stock. a product_id (INTEGER) a store_id (INTEGER) a quantity (INTEGER) in stock Now we can insert some stores, products and inventory into our database. There are 2 stores -- one called NY and one called NJ. There are 2 products we are concerned with. Their names are sneakers, costing $220 (remember this is dollars!) and boots costing $350. Use any description for each that you'd like. NY has 4 sneakers in stock and 3 boots. NJ has 5 sneakers in stock and no boots. Insert the above data into the tables you have created.
Write a stored procedure called sp_apply_discount() that will apply percent discount to books in a subject. The stored procedure takes in 2 parameters, percentDiscount (DECIMAL(8,2)) and subject (VARCHAR(120)). Using these parameters, the stored procedure computes the discount for the book cost and stores it in the FINAL_PRICE field. For example, the following stored procedure call: call sp_apply_discount(0.15, 'Database');would compute 15% percent discount from the book cost in the Database subject category and store it in the FINAL_PRICE column as depicted in this image:
