A propellant management device (PMD) provides a way to expel propellant in a low-gravity environment. Devices can use surface tension as the primary expulsion device with a combination of baffles, fins, and vanes. The main goal of the PMD is to provide gas-free propellant to the rocket engine. [1]
The Ethernet PMD sublayer is part of the Ethernet physical layer (PHY). The hierarchy is as follows: Data link layer (Layer 2) Logical link control (LLC) sublayer; Medium access control (MAC) sublayer Reconciliation sublayer (RS) – This sublayer processes PHY local/remote fault messages and handles DDR conversion; PHY layer (Layer 1)

The blade battery is most commonly a 96 centimetres (37.8 in) long and 9 centimetres (3.5 in) wide single-cell battery with a special design, which can be placed in an array and inserted into a battery pack like a blade. It is made in various lengths and thicknesses.
Polarization mode dispersion (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical pulses. Unless it is compensated, which is difficult, this ultimately ...
