A useful macroscopic model that combines an electric field with DLA was developed by Niemeyer, Pietronero, and Weismann in 1984, and is known as the dielectric breakdown model (DBM). [7] Although the electrical breakdown mechanisms of air and PMMA plastic are considerably different, the branching discharges turn out to be related.
Diagram of a MMRTG. The multi-mission radioisotope thermoelectric generator (MMRTG) is a type of radioisotope thermoelectric generator (RTG) developed for NASA space missions [1] such as the Mars Science Laboratory (MSL), under the jurisdiction of the United States Department of Energy's Office of Space and Defense Power Systems within the Office of Nuclear Energy.
Enterprise architecture regards the enterprise as a large and complex system or system of systems. [3] To manage the scale and complexity of this system, an architectural framework provides tools and approaches that help architects abstract from the level of detail at which builders work, to bring enterprise design tasks into focus and produce valuable architecture description documentation.
These elements are widely used to model the function of two-port networks; one generator is needed for each port, and it is dependent on either voltage or current at the other port. The models are an example of black box modelling; that is, they are quite unrelated to what is physically inside the device but correctly model the device's ...
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.
Arbitrary waveform generators may have distortion less than -55 dB below 50 kHz and less than -40 dB above 50 kHz. Some function generators can be phase locked to an external signal source, which may be a frequency reference or another function generator. Amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM) may be ...
In 2014, the Post found some parts of the process were being done by computer. Last summer, Federal News Network reported the department was testing a pilot online retirement application.
