In electricity generation, a generator [1] is a device that converts motion-based power ( potential and kinetic energy) or fuel-based power ( chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even ...
Homopolar generator. Faraday disk, the first homopolar generator. A homopolar generator is a DC electrical generator comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. A potential difference is created between the center of the disc and the rim (or ends of the cylinder ...
Kali Code and nearby homes in Yogyakarta during the 2014 eruption of Kelud in East Java. Code ( Indonesian pronunciation: [tʃode]; Indonesian: Kali Code) is the name of a river that flows through the city of Yogyakarta on the island of Java, Indonesia. [1] [2] [3] Pollution is a problem along the river. [4] Sayidan Bridge crosses the river.
Polynomial code. In coding theory, a polynomial code is a type of linear code whose set of valid code words consists of those polynomials (usually of some fixed length) that are divisible by a given fixed polynomial (of shorter length, called the generator polynomial ).
Radionuclide generator. A radionuclide generator is a device which provides a local supply of a short-lived radioactive substance from the decay of a longer-lived parent radionuclide. They are commonly used in nuclear medicine to supply a radiopharmacy. [1] The generator provides a way to separate the desired product from the parent, typically ...
In mathematical terms, Hamming codes are a class of binary linear code. For each integer r ≥ 2 there is a code-word with block length n = 2r − 1 and message length k = 2r − r − 1. Hence the rate of Hamming codes is R = k / n = 1 − r / (2r − 1), which is the highest possible for codes with minimum distance of three (i.e., the minimal ...
The largest air-insulated Van de Graaff generator in the world, built by Dr. Van de Graaff in the 1930s, is now displayed permanently at Boston's Museum of Science. With two conjoined 4.5 m (15 ft) aluminium spheres standing on columns 22 ft (6.7 m) tall, this generator can often obtain 2 MV (2 million volts).
Generator (computer programming), a routine that acts like an iterator; Pseudorandom number generator, a producer of random numbers; Code generator, part of a compiler; Natural-language generator, generating natural language from a machine representation system such as a knowledge base or a logical form; Random test generator, used in software ...
