Assume a list of measurements (x), recorded at different times (t). Since the measurements may grow over time or may have been recorded at a high-frequency, we would like to 'downsample' (or 'compress'/'aggregate') the data, that is, reducing the frequency of the original signal. One way to do so is to assume a fixed 'window' of time, and aggregate the data recorded within that window.
Example: Given x = [1., 2., 3., 4.], t = [10, 11, 14, 15] and a window size of 2, we may want to get the average of the signal within that period of time. – downsampled_t = [10, 14] - downsampled_x = [1.5, 3.5] # 1.5 = (1+2)/2; 3.5 = (3+4)/2
Q1 - Downsampler class
Write a class Downsampler with methods to: * i) downsample a signal; * ii) iterate through the compressed signal; * iii) get the downsampled value(s) at a given time
Assumptions: - x is a list of floating numbers. - t is a list of integers (e.g 'Unix time' - Wikipedia) - You can assume the mean, max, min and number of data points of the signal within a time window are the quantities of interest.
Example:
# Define class
downsampler = Downsample(window_size=2)
# Define signal
>>> x = [1., 2., 3., 4.]; t = [10, 11, 14, 15]
# Downsample
>>> downsampler.downsample(t, x)
# Get downsampled values
>>> results = downsampler[10.5]
>>> print(results)
(10: {'mean': 1.5, 'max': 2, 'min': 1, 'n_points': 2})
# Iterate through the compressed signal
>>> for ds_t, ds_x in downsampler:
... print(ds_t, ds_x)
10, {'mean': 1.5, 'max': 2, 'min': 1, 'n_points': 2}
14, {'mean': 3.5, 'max': 4, 'min': 3, 'n_points': 2}
Notes: - Your implementation should not use any data processing library (for instance - pandas). - Libraries used for array manipulation are accepted (for instance - numpy). - Your implementation may differ from the example below, which is given for illustration purposes.

Answer:

The answer is "\(\bold{Brand \ A \ (35, 350, 18.7) \ \ Brand \ B \ (35, 50, 7.07)}\)"

Explanation:

Calculating the mean for brand A:

\(\to \bar{X_{A}}=\frac{10+60+50+30+40+20}{6} =\frac{210}{6}=35\)

Calculating the Variance for brand A:

\(\sigma_{A}^{2}=\frac{\left ( 10-35 \right )^{2}+\left ( 60-35 \right )^{2}+\left ( 50-35 \right )^{2}+\left ( 30-35 \right )^{2}+\left ( 40-35 \right )^{2}+\left ( 20-35 \right )^{2}}{5} \\\\\)

     \(=\frac{\left ( -25 \right )^{2}+\left ( 25 \right )^{2}+\left ( 15\right )^{2}+\left ( -5 \right )^{2}+\left ( 5 \right )^{2}+\left ( 15 \right )^{2}}{5} \\\\ =\frac{625+ 625+225+25+25+225}{5} \\\\ =\frac{1750}{50}\\\\=350\)

Calculating the Standard deviation:

\(\sigma _{A}=\sqrt{\sigma _{A}^{2}}=18.7\)

Calculating the Mean for brand B:

\(\bar{X_{B}}=\frac{35+45+30+35+40+25}{6}=\frac{210}{6}=35\)

Calculating the Variance for brand B:

\(\sigma_{B} ^{2}=\frac{\left ( 35-35 \right )^{2}+\left ( 45-35 \right )^{2}+\left ( 30-35 \right )^{2}+\left ( 35-35 \right )^{2}+\left ( 40-35 \right )^{2}+\left ( 25-35 \right )^{2}}{5}\)

    \(=\frac{\left ( 0 \right )^{2}+\left ( 10 \right )^{2}+\left ( -5 \right )^{2}+\left (0 \right )^{2}+\left ( 5 \right )^{2}+\left ( -10 \right )^{2}}{5}\\\\=\frac{0+100+25+0+25+100}{5}\\\\=\frac{100+25+25+100}{5}\\\\=\frac{250}{5}\\\\=50\)

 Calculating the Standard deviation:  

\(\sigma _{B}=\sqrt{\sigma _{B}^{2}}=7.07\)

The way that the tribes profit most from cattle drives that passed through their land is option D. By leasing grazing land to ranchers and drovers from Texas.

When Oklahoma became a state in 1907, the reservation system there was essentially abolished. In Indian Territory, cattle were and are the dominant economic driver.

Tolls on moving livestock, exporting their own animals, and leasing their territory for grazing were all sources of income for the tribes.

There were several cattle drives between 1867 and 1893. Cattle drives were conducted to supply the demand for beef in the east and to provide the cattlemen with a means of livelihood after the Civil War when the great cities in the northeast lacked livestock.

Based on illustration about Alison above, she should move the emails she doesn’t need to the folder.

The email inbox is often full of messages from various shipping categories. Starting from promotional emails, email updates, job emails, and more. If all of these messages are together in one folder in the inbox, it will be very annoying when you are waiting for an important email, because it could be mixed with other emails until it finally sinks and you don't see the message at the top.

Given the large number of incoming emails in your inbox, creating system folders can help you manage your existing inboxes. You can categorize this folder based on how important the email is to you.

Apart from creating filters, another thing you can use to manage your emails is to create labels for them. You can create labels that can store your emails. Add as many labels as you need. Note that this label is different from the folder. When you delete a message on a label, that message is deleted from any labels associated with it.

Merge Sort method stops partitioning and starts returning when the list is split into one or zero elements. In other words, when there are no more elements left to partition the sub-lists any further, the Merge Sort method will return.

The sub-lists are divided again and again into halves until the list cannot be divided further. Then we combine the pair of one element lists into two-element lists, sorting them in the process.

The sorted two-element pairs is merged into the four-element lists, and so on until we get the sorted list.Merging is the next step in the sorting process.

The merging process puts the split lists back together into a single list, which is now ordered. As a result, the sorted sub-lists can now be merged into a single sorted list with more than 100 elements.

To encrypt and decrypt messages using the Caesar Cipher in C with file IO, follow these steps: Define the cipher, create, write, read, encrypt, and decrypt the message, and write the results to new files.

To practice using file IO to encrypt and decrypt messages using the Caesar Cipher in the C Language, you can follow these

Define the Caesar CipherThe Caesar Cipher is a simple substitution cipher that shifts letters by a certain number of places. For example, if the shift is 3, then the letter "A" becomes "D", "B" becomes "E", and so on. To define the Caesar Cipher in C, you can use a function that takes a character and a shift value as arguments and returns the shifted character.

For example, the following function takes a character and a shift value and returns the shifted character:```char caesar(char ch, int shift){ if (isalpha(ch)){ char base = isupper(ch) ? 'A' : 'a'; return (ch - base + shift) % 26 + base;} else { return ch; }}```

Create a file to store the messageTo store the message, you can create a file using the fopen() function. For example, the following code creates a file named "message.txt" for writing:```FILE* file = fopen("message.txt", "w");```

Write the message to the fileTo write the message to the file, you can use the fputs() function. For example, the following code writes the message "HELLO WORLD" to the file:```fputs("HELLO WORLD", file);```

Read the message from the fileTo read the message from the file, you can use the fgets() function. For example, the following code reads the message from the file:```char message[100];fgets(message, 100, file);```

Encrypt the messageTo encrypt the message, you can use the caesar() function to shift each letter by a certain number of places. For example, the following code encrypts the message using a shift of 3:```for (int i = 0; message[i] != '\0'; i++){ message[i] = caesar(message[i], 3); }}```

Write the encrypted message to a new fileTo write the encrypted message to a new file, you can create a new file using the fopen() function and write the encrypted message to the file using the fputs() function. For example, the following code creates a file named "encrypted.txt" for writing and writes the encrypted message to the file:```FILE* file = fopen("encrypted.txt", "w");fputs(message, file);```

Read the encrypted message from the fileTo read the encrypted message from the file, you can use the fgets() function. For example, the following code reads the encrypted message from the file:```char encrypted[100];fgets(encrypted, 100, file);```

Decrypt the messageTo decrypt the message, you can use the caesar() function to shift each letter back by a certain number of places. For example, the following code decrypts the message using a shift of 3:```for (int i = 0; encrypted[i] != '\0'; i++){ encrypted[i] = caesar(encrypted[i], -3); }}```9. Write the decrypted message to a new file.

To write the decrypted message to a new file, you can create a new file using the fopen() function and write the decrypted message to the file using the fputs() function. For example, the following code creates a file named "decrypted.txt" for writing and writes the decrypted message to the file:```FILE* file = fopen("decrypted.txt", "w");fputs(encrypted, file);```
