Morse code abbreviations are not the same as prosigns.Morse abbreviations are composed of (normal) textual alpha-numeric character symbols with normal Morse code inter-character spacing; the character symbols in abbreviations, unlike the delineated character groups representing Morse code prosigns, are not "run together" or concatenated in the way most prosigns are formed.
In that word, tall letters (those descending below the baseline or ascending above the mean line – b, d, f, g, h, j, k, l, p, q, t, or y) and capital letters represent dashes, while short letters (aceimnorsuvwxz) represent dots. To recall the Morse code for a character, try to visualize the word.
The Morse code, as specified in the current international standard, International Morse Code Recommendation, ITU-R M.1677-1, [1] was derived from a much-improved proposal by Friedrich Gerke in 1848 that became known as the "Hamburg alphabet", its only real defect being the use of an excessively long code ( and later the equal duration code ...
The Morse–Palais lemma, one of the key results in Morse theory, is named after him, as is the Thue–Morse sequence, an infinite binary sequence with many applications. He was elected to the American Academy of Arts and Sciences in 1929, [ 1 ] the United States National Academy of Sciences in 1932, [ 2 ] and the American Philosophical Society ...
For example, the word "encyclopedia" is a sequence of symbols in the English alphabet, a finite set of twenty-six letters. Since a word can be described as a sequence, other basic mathematical descriptions can be applied. The alphabet is a set, so as one would expect, the empty set is a subset. In other words, there exists a unique word of ...

Since T n does not contain overlapping squares, the words q n are palindromic squarefree words. The Thue–Morse morphism μ is defined on alphabet {0,1} by the substitution map μ(0) = 01, μ(1) = 10: every 0 in a sequence is replaced with 01 and every 1 with 10. [12] If T is the Thue–Morse sequence, then μ(T) is also T. Thus, T is a fixed ...
American Morse Code — also known as Railroad Morse—is the latter-day name for the original version of the Morse Code developed in the mid-1840s, by Samuel Morse and Alfred Vail for their electric telegraph.
