71Bipolar transistor biasing — Bipolar transistor amplifiers must be properly biased to operate correctly. In circuits made with individual devices (discrete circuits), biasing networks consisting of resistors are commonly employed. Much more elaborate biasing arrangements are …
72Power MOSFET — A Power MOSFET is a specific type of Metal Oxide Semiconductor Field Effect Transistor (MOSFET) designed to handle large power. Compared to the other power semiconductor devices (IGBT, Thyristor...), its main advantages are high commutation speed …
73Robijn Bruinsma — Robijn F. Bruinsma (b. May 15, 1953, Haarlem, The Netherlands) is a theoretical physicist and is Professor of Physics at the University of California at Los Angeles and Chair of the Department of Theoretical Physics for the Life Sciences at… …
74Nanoflares — A nanoflare is a very small solar flare which happens in the corona, the external atmosphere of the Sun. The hypothesis of microflares as a possible explanation of the coronal heating was first suggested by Gold [1] and then later developed by… …
75Fluctuation theorem — The fluctuation theorem (FT) is a theorem from statistical mechanics dealing with the relative probability that the entropy of a system which is currently away from thermodynamic equilibrium (maximum entropy) will increase or decrease over a… …
76Heat death of the universe — For the album, see The Heat Death of the Universe. Physical cosmology Universe  …
77Low-power electronics — means that the consumption of electric power is deliberately low, e.g. notebook processors. Electronics The density and speed of integrated circuit computing elements has increased roughly exponentially for a period of several decades, following… …
78vacuum technology — Introduction all processes and physical measurements carried out under conditions of below normal atmospheric pressure. A process or physical measurement is generally performed in a vacuum for one of the following reasons: (1) to remove the …
79MOSFET — Two power MOSFETs in the surface mount package D2PAK. Operating as switches, each of these components can sustain a blocking voltage of 120 volts in the OFF state, and can conduct a continuous current of 30 amperes in the ON state, dissipating up …
80Post-glacial rebound — A model of present day mass change due to post glacial rebound and the reloading of the ocean basins with seawater. Blue and purple areas indicate rising due to the removal of the ice sheets. Yellow and red areas indicate falling as mantle… …
