Há 3 dias · The Hamming code concepts can be described in matrix form, where a generating matrix (G) creates valid codewords from information bits, and a check matrix (H) computes syndromes for error checking. When a valid codeword is multiplied by the check matrix, the result (syndrome) is zero.
Há 5 dias · If an additional parity bit (P) is appended to the Hamming code as shown in the diagram at right, the resulting (8,4) codewords in the Extended Hamming Code will have distance (d=4). The new check bit (P) is computed as the even parity of the entire 7-bit Hamming code and improves the performance of the Hamming code whenever two bit errors occur.
Há 5 dias · In contrast, one can look for generalized Duffing equation. d2x dt2 + x2n + 1 + 2n ∑ i = 0pi(t)xi = f(t), which allow to conclude that all the solutions of the equation are bounded. This result, prompted by Littlewood, is due to G.R. Morris, Matkus, Moser, You, and Yuan. Theorem: Every solution to the homogeneous generalized Duffing equation.

Há 4 dias · The hamming distance between two integers is the number of bits which differ in them. To compute the hamming distance, we xor the two integers bitwise and count the number of bits set. This works because the xor yields 1 only when both bits are different.
Há 4 dias · Alternative or additional filterering tests are: cross check test (good match \( \left( f_a, f_b \right) \) if feature \( f_b \) is the best match for \( f_a \) in ...
Há 5 dias · Alan Turing (born June 23, 1912, London, England—died June 7, 1954, Wilmslow, Cheshire) was a British mathematician and logician who made major contributions to mathematics, cryptanalysis, logic, philosophy, and mathematical biology and also to the new areas later named computer science, cognitive science, artificial intelligence, and ...
