Answer:

Bayesian filtering

Explanation:

This is a type of filtering software that makes use of Bayesian logic to evaluate every incoming email that you receive, analyzing the header and content of the email to determinate if it is spam or not. It uses a preset of common words that are present in most spam emails, and it categorizes all received emails according to their probability to contain spam in trusted, or not trusted email. These categories are usually set by the user.

In short, Bayesian logic uses the knowledge acquired from past events to try to predict future events. Determinate the probability of success (from 0 to 100%) of a certain activity, according to the result of prior tests. It was first suggested in 1763 after the death of its creator Thomas Bayes, and it is widely spread across several different sciences such as programming, artificial intelligence, physics, etc.

The scheme function (mult2-diff Ist) should take one argument, a list of numbers, and results in multiplying each number in the
JulijaS [17]

Answer:

The solution code is written in Python.

  1. def mult2_diff(lst):
  2.    num_list = []
  3.    for x in lst:
  4.        num_list.append(x * 2)
  5.    diff = num_list[0]
  6.    for i in range(1, len(num_list)):
  7.        diff = diff - num_list[i]
  8.    
  9.    print(diff)

Explanation:

Firstly, based on the requirement stated in the question, define a function <em>mult2_diff() </em>that takes one argument, <em>lst</em>, which is a list of numbers (Line 1).

This function is expected to multiply each number in the list by two and then followed with computing the difference. To do so, let's try to attempt the first function task, multiplying numbers.  Create a new list, num_list, to hold the multiplied numbers (Line 2). Use a for loop to traverse through each number in the input list, <em>lst</em>, and multiply each of them by two and add it to the <em>num_list </em>(Line 4-5).

To attempt the second function task, create another variable, <em>diff</em>, to hold the value of calculated difference between the numbers in the <em>num_list</em>. Initialize <em>diff </em>with the first number in the <em>num_list</em>. Use a another for-loop to traverse through each number in the num_list starting with second index, <em>1</em>, and calculate the difference between the <em>diff </em>and the current number extracted from the <em>num_list </em>through indexing.

At last print the output of <em>diff</em> (Line 11).

A smart refrigerator can use what to detect when you are running low on milk, and then send a reminder to you on a wireless.
Olegator [25]

Answer:

RFID scanning or Barcode reader

Explanation

Smart refrigerators have inbuilt RFID scanning technology that help monitor the stock that is inside your fridge. Once you pass your items through the inbuilt RFID scanner in the fridge, the barcode of your items is cross-referenced with a database and given a unique tag for identification. This technology helps detect and track the stock that is inside your fridge and when you start running low, the RFID can be triggered to send a reminder as a notification on your email or a text message.
