For the prefix "Stego-" as used in taxonomy, see List of commonly used taxonomic affixes. The same image viewed by white, blue, green, and red lights reveals different hidden numbers. Steganography ( / ˌstɛɡəˈnɒɡrəfi / ⓘ STEG-ə-NOG-rə-fee) is the practice of representing information within another message or physical object, in such ...
Material: vellum: Size: ≈ 23.5 cm × 16.2 cm × 5 cm (9.3 in × 6.4 in × 2.0 in) Format: One column in the page body, with slightly indented right margin and with paragraph divisions, and often with stars in the left margin; [12] the rest of the manuscript appears in the form of graphics (i.e. diagrams or markings for certain parts related to illustrations), containing some foldable parts
Codex. The codex ( pl.: codices / ˈkoʊdɪsiːz /) [1] was the historical ancestor of the modern book. Instead of being composed of sheets of paper, it used sheets of vellum, papyrus, or other materials. The term codex is often used for ancient manuscript books, with handwritten contents. [2] A codex is bound by stacking the pages and securing ...
Thematic analysis is used in qualitative research and focuses on examining themes or patterns of meaning within data. [ 12] This method can emphasize both organization and rich description of the data set and theoretically informed interpretation of meaning. [ 1] Thematic analysis goes beyond simply counting phrases or words in a text (as in ...
t. e. In cryptography, a substitution cipher is a method of encrypting in which units of plaintext are replaced with the ciphertext, in a defined manner, with the help of a key; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth. The receiver deciphers the text by ...
Viterbi decoding allows asymptotically optimal decoding efficiency with increasing constraint length of the convolutional code, but at the expense of exponentially increasing complexity. A convolutional code that is terminated is also a 'block code' in that it encodes a block of input data, but the block size of a convolutional code is ...
Reading. The simple view of reading is a scientific theory that a student's ability to understand written words depends on how well they sound out (decode) the words and understand the meaning of those words. Specifically, their reading comprehension can be predicted by multiplying their skill in decoding the written words by their ability to ...
Frequency analysis is based on the fact that, in any given stretch of written language, certain letters and combinations of letters occur with varying frequencies. Moreover, there is a characteristic distribution of letters that is roughly the same for almost all samples of that language. For instance, given a section of English language, E, T ...
