Mathematical meaning of principal component analysis (PCA)
This article aims at explaining the mathematical sense of the Principal Component Analysis (PCA) in practice.
Pixel image rotation
Brief problem formulation
The program accepts as input the absolute path to the image in the bmp extension and the path where you save the result of the work. Then, it rotates the image by 90 degrees counterclockwise. Afterwards, the program saves the new image.
The program is executed on C.
Blinking into Morse code
Explaining main algorithm.
For a while I’ve been thinking of writing a scientific article. I wanted it to have certain utility.
Morse code is binary: it takes only two values – either dot (short) or hyphen (long). I figured out that short (s) can stand for two-eye blinking whilst long (l) can indicate left-eye blinking. Another question emerged: how to understand when does one-symbol recording stop?
Empty space between two symbols can be presented by right-eye blinking – r. If I input singly symbol of short (dot) and long (hyphen), I will blink my right eye once to indicate the space between two symbols.
To separate independent words, one has to blink her right eye twice and get rr.
Hence, I have collected an ordered set of symbols – r, l, s, - that can be converted into a full-fledged text. Once I accomplish the transformation, I get an answer.
