Simulation of High-Altitude Electromagnetic Pulse (HEMP) above Sea Surface
High-altitude electromagnetic pulse (HEMP) radiated from both primary and secondary currents, which are induced by a nuclear explosion, is computed by using the Jefimenko’s equation. The effects of geomagnetic field is considered in computing the primary current, and the rough sea surface is considered in computing the reflected electric field in the frequency domain. The waveforms of HEMP near...
متن کاملRisetime Evolution in HEMP (High-Altitude Electromagnetic Pulse) E1Waveforms - Technology and Standards
There are many different definitions of the risetime of a transient waveform. In the context of HEMP standards, the 10-90% risetime of an idealized double exponential waveform has been defined and used for many decades. However, such a risetime definition is not strictly applicable to the transient voltage out of a pulse generator, since no practical switch can close in zero time. In this paper...
متن کاملPulse oximetry at high altitude.
Pulse oximetry is a valuable, noninvasive, diagnostic tool for the evaluation of ill individuals at high altitude and is also being increasingly used to monitor the well-being of individuals traveling on high altitude expeditions. Although the devices are simple to use, data output may be inaccurate or hard to interpret in certain situations, which could lead to inappropriate clinical decisions...

according to research, academic self-concept and academic achievement are mutually interdependent. in the present study, the aim was to determine the relationship between the academic self-concept and the academic achievement of students in english as a foreign language and general subjects. the participants were 320 students studying in 4th grade of high school in three cities of noor, nowshah...
A Modified Description of Early Time High-altitude Electromagnetic Pulse Waveform (E1)
The mathematical description of High-altitude Electromagnetic Pulse (HEMP) waveform (E1) in the standard of IEC 61000-2-9 is the difference of double exponentials (DEXP). However, in this description there is a discontinuity of the first derivative at the initial time of waveform. Another analytic waveform description, the quotient of double exponentials (QEXP) has the advantage of all time der...
