In mathematics, a polyphasesequence is a sequence whose terms are complex roots of unity: a n = e i 2 π q x n {\displaystyle a_{n}=e^{i{\frac {2\pi }{q}}x_{n}}\...
Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Numbers that are part of the Fibonacci sequence are known...
construction of sequences of any length of the form 2N10K26M. Later the theory of complementary sequences was generalized by other authors to polyphase complementary...
A polyphase merge sort is a variation of a bottom-up merge sort that sorts a list using an initial uneven distribution of sub-lists (runs), primarily...
defined in any system, the definition of apparent power for unbalanced polyphase systems is considered to be one of the most controversial topics in power...
dot products are performed simultaneously, in which case it is called a polyphase filter. For completeness, we now mention that a possible, but unlikely...
without increasing the currents maximum absolute value. The armature of polyphase electric machines includes multiple windings powered by the AC currents...
demonstrated that any set of N unbalanced phasors (that is, any such polyphase signal) could be expressed as the sum of N symmetrical sets of balanced...
CCK is a variation and improvement on M-ary Orthogonal Keying and uses 'polyphase complementary codes'. They were developed by Lucent Technologies and Harris...

propel his invention, the electricity meter. The first AC commutator-free polyphase induction motors were independently invented by Galileo Ferraris and Nikola...
Walter Baily, who gave a workable demonstration of his battery-operated polyphase motor aided by a commutator on 28 June 1879, to the Physical Society of...
each other by a sequence of lifting steps. For a better understanding, if P {\displaystyle P} and Q {\displaystyle Q} are polyphase matrices with the...
sophisticated merge sort that optimizes tape (and disk) drive usage is the polyphase merge sort. On modern computers, locality of reference can be of paramount...
FFTs. Then the FFT filter bank can be described in terms of one or more polyphase filter structures where the phases are recombined by an FFT instead of...
stepper, or stepping, motor is a synchronous, brushless, high pole count, polyphase motor. Control is usually, but not exclusively, done open loop, i.e.,...
angle between the systems must be zero (and two polyphase systems must have the same phase sequence). Synchroscopes measure and display the frequency...
billion years old. The Narryer Gneiss Terrane has undergone many high-grade polyphase deformation events, with the most notable being at 2600 to 2700 Ma associated...
power factor of a balanced polyphase circuit is the same as that of any phase. The power factor of an unbalanced polyphase circuit is not uniquely defined...
the number of input tape volumes, up to a maximum of 15 input reels. Polyphase (POLY) - required a minimum of 12,000 bytes and 3 intermediate storage...
achieved its first practical induction motor in 1892 and developed a line of polyphase 60 hertz induction motors in 1893, but these early Westinghouse motors...
range is marked by the Pieniny Klippen Belt, a narrow complicated zone of polyphase compressional deformation, later involved in a supposed strike-slip zone...
and other devices to limit the loss of service due to a failure. In a polyphase system, a fault may affect all phases equally, which is a "symmetric fault"...
