CASE: PepsiCo
“Take PepsiCo, for example. As one of the leading soft drink makers and bottlers, PepsiCo turned to IoT for the most basic of reasons and found an efficient solution. Like many enterprises, the company had inefficient and ineffective IT and OT infrastructure, as well as limited IT and OT resources available inside its plants. It also suffered from server sprawl, where each server supported a very small portion of the production load. PepsiCo essentially incurred high costs to purchase and support an ever-expanding infrastructure of underutilized servers, operating systems, and networking assets. The result: highly inefficient use of capital—at a minimum. Even worse, its inefficient network hindered the collection of data that would ordinarily drive plant productivity.”

What were the paybacks to PepsiCo after implementing IoT? Elaborate.

Answer the following questions based on this scenario.

Problem: Write a program that reads 10 username and password values into parallel arrays. After the arrays have been loaded, the program should behave like a login screen, prompting for a username and a password. Based on the data read and stored in the arrays, the program should respond appropriately with one of three output messages: “Username not found.”, “Username and password does not match.” or “Access granted.”

Question 1: Would you write this program asking a user to enter the usernames and passwords or would you use a file that contains all the username and passwords as input?  Explain why you would choose one over the other.  

Question 2: Will your answer remain the same if the number of username and password values change to 40, and why?

Use the following help function to pull the data on r

??gafa_stock
??PBS
??vic_elec
??pelt

I just need the code to run it.

8. Tsibble and mutate practice: Import a year of stock (of your choosing) closing price data (feel free to use gafa_stock within FPP3 or quantmod package. Convert this data to a tsibble. Plot differences and correlogram of the differences and comment on whether the differences resemble white noise (reference FPP3 2.10, #12 for code help dFB <- gafa_stock %>%
filter(Symbol == “FB”, year(Date) >= 2018) %>%
mutate(trading_day = row_number()) %>%
update_tsibble(index = trading_day, regular = TRUE) %>%
mutate(diff = difference(Close))
view(dFB)).

9. Reindexing and plotting practice: Vic_elec dataset

a. Plot daily demand year over year for vic_elec dataset (within FPP3)

b. Is temperature correlated to demand?

c. Is previous day demand correlated with current demand?

For below problems please reference https://r4ds.had.co.nz/dates-and-times.html

10. Datetime components: nycflights13 (

library(nycflights13)

#ensure you have the tables loaded and preview
flights
weather

#check what tables are in the ‘nycflights13’ package
data(package=’nycflights13′))

a. Load the flights table from the nycflights13 package

b. What day of the week has the highest average delay?

11. Time zones: Reindex vic_elec to the US Eastern timezone using the with_tz function

12. Durations and periods

a. Create a duration for your age at the start of our first lecture and print this duration.

b. Calculate your age at the end of the semester (4/27/22 8:50p) using periods
