Magnetic flux. In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or ΦB. The SI unit of magnetic flux is the weber (Wb; in derived units, volt–seconds), and the CGS unit is the maxwell.
An explosively pumped flux compression generator ( EPFCG) is a device used to generate a high-power electromagnetic pulse by compressing magnetic flux using high explosive . An EPFCG only ever generates a single pulse as the device is physically destroyed during operation. They require a starting current pulse to operate, usually supplied by ...
Fluxus 1 is an artists' book edited and produced by the Lithuanian-American artist George Maciunas, containing works by a series of artists associated with Fluxus, the international collective of avant-garde artists primarily active in the 1960s and 1970s. Originally published in New York, 1964, the contents vary from edition to edition, but ...
A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.
A key generator [1] [2] [3] is a protocol or algorithm that is used in many cryptographic protocols to generate a sequence with many pseudo-random characteristics. This sequence is used as an encryption key at one end of communication, and as a decryption key at the other. One can implement a key generator in a system that aims to generate ...
Zone 8 uses four 2-digit codes (81, 82, 84, 86) and four sets of 3-digit codes (80x, 85x, 87x, 88x) to serve East Asia, South Asia and special services. 83x and 89x are unallocated. Zone 9 uses seven 2-digit codes (90–95, 98) and three sets of 3-digit codes (96x, 97x, 99x) to serve the Middle East , West Asia , Central Asia , parts of South ...
Benjamin Patterson was born in Pittsburgh on May 29, 1934. He attended the University of Michigan from 1952 to 1956, where he studied the contrabass, Composition, and Film Direction. As an African-American musician, he found it impossible to get a job at a symphony orchestra in the United States [vague][citation needed], so he started playing ...
The PBKDF2 key derivation function has five input parameters: [ 9] DK = PBKDF2 (PRF, Password, Salt, c, dkLen) where: PRF is a pseudorandom function of two parameters with output length hLen (e.g., a keyed HMAC) Password is the master password from which a derived key is generated. Salt is a sequence of bits, known as a cryptographic salt.
