Wilkinson power divider. In the field of microwave engineering and circuit design, the Wilkinson Power Divider is a specific class of power divider circuit that can achieve isolation between the output ports while maintaining a matched condition on all ports. The Wilkinson design can also be used as a power combiner because it is made up of ...
A split-ring resonator array is configured as a material that produces a negative index of refraction. It was constructed of copper split-ring resonators and wires mounted on interlocking sheets of fiberglass circuit board. The total array consists of 3 by 20×20 unit cells with overall dimensions of 10×100×100 mm. [ 1][ 15] Split-ring ...
A split-phase or single-phase three-wire system is a type of single-phase electric power distribution. It is the alternating current (AC) equivalent of the original Edison Machine Works three-wire direct-current system. Its primary advantage is that, for a given capacity of a distribution system, it saves conductor material over a single-ended ...
Splitting field. In abstract algebra, a splitting field of a polynomial with coefficients in a field is the smallest field extension of that field over which the polynomial splits, i.e., decomposes into linear factors.
The Spearman–Brown prediction formula, also known as the Spearman–Brown prophecy formula, is a formula relating psychometric reliability to test length and used by psychometricians to predict the reliability of a test after changing the test length. [1] The method was published independently by Spearman (1910) and Brown (1910).
A split-complex number is an ordered pair of real numbers, written in the form. where x and y are real numbers and the hyperbolic unit [1] j satisfies. In the field of complex numbers the imaginary unit i satisfies The change of sign distinguishes the split-complex numbers from the ordinary complex ones.
Negative split. A negative split is a racing strategy that involves completing the second half of a race faster than the first half. It is defined by the intentional setting of a slower initial pace, followed by a gradual or sudden increase of speed towards the end of the race. [1] Alternate strategies include even splitting (racing at a steady ...
A reverse stock split occurs on an exchange basis, such as 1-10. When a company announces a 1-10 reverse stock split, for example, it exchanges one share of stock for every 10 that a shareholder owns.
