An inrush current limiter is a device or devices combination used to limit inrush current. Passive resistive components such as resistors (with power dissipation drawback), or negative temperature coefficient (NTC) thermistors are simple options while the positive one (PTC) is used to limit max current afterward as the circuit has been operating (with cool-down time drawback on both).
Devices with a higher proportion of yield derived from this reaction would be more efficient in the stand-off asteroid impact avoidance role, due to the penetrative depth of fast-neutrons and the resulting higher momentum transfer that is produced in this "scabbing" of a much larger mass of material free from the main body, as opposed to the ...
It was a very compact pure fission device weighing 50.9 pounds (23.1 kg) and when packaged in the M388 round weighed 76 pounds (34 kg). The warhead had a yield equivalent to 20 tonnes of TNT (84 GJ) and contained 26 pounds (12 kg) of high explosives. [15] [2] There was also a 10 tonne, TNT equivalent, variant. [16] [17] [18]
Detonated in 1953 with a yield equivalent to 400 kt (1,700 TJ) (only 15%– 20% from fusion), the Sloika device did, however, have the advantage of being a weapon which could actually be delivered to a military target, unlike the "Ivy Mike" device, though it was never widely deployed. Teller had proposed a similar design as early as 1946 ...
A charged device model (CDM) test is used to define the ESD a device can withstand when the device itself has an electrostatic charge and discharges due to metal contact. This discharge type is the most common type of ESD in electronic devices and causes most of the ESD damages in their manufacturing.
Yield protection, sometimes called Tufts syndrome (after Tufts University), is a verified admissions practice in which an academic institution rejects or delays the acceptance of highly qualified students on the grounds that such students are likely to be accepted by, and then enroll in, more selective institutions.
A fizzle occurs when the detonation of a device for creating a nuclear explosion (such as a nuclear weapon) grossly fails to meet its expected yield. The bombs still detonate, but the detonation is much weaker than anticipated. The cause(s) for the failure might be linked to improper design, poor construction, or lack of expertise.
Mk. 82 bomb with a Snake Eye Tail Retarding Device – this photograph shows an unfuzed, museum display Mk82 with its usual combat paint scheme. For display purposes, the optional high-drag Snake Eye tailfin set used for low-altitude release is shown.
