The Weber number appears in the incompressible Navier-Stokes equations through a free surface boundary condition. [ 3 ] For a fluid of constant density ρ {\displaystyle \rho } and dynamic viscosity μ {\displaystyle \mu } , at the free surface interface there is a balance between the normal stress and the curvature force associated with the ...
Class B vacuum tube amplifiers are usually operated with grid current (class B 2). The bias voltage source must have low resistance and be able to supply the grid current. [3] When tubes designed for class B are employed, the bias can be as little as zero. Class C amplifiers are biased negatively at a point well beyond plate current cutoff ...
Joseph Warren Robinett Jr. (born December 25, 1951) [1] is an American video game designer. He is most notable as the developer of the Atari 2600's Adventure and as a founder of The Learning Company, [1] where he designed Rocky's Boots [2] and Robot Odyssey. More recently he has worked on virtual reality projects.
Tape bias is the term for two techniques, AC bias and DC bias, that improve the fidelity of analogue tape recorders. DC bias is the addition of direct current to the audio signal that is being recorded. AC bias is the addition of an inaudible high-frequency signal (generally from 40 to 150 kHz) to the audio signal. Most contemporary tape ...
A bias tee is a three-port network used for setting the DC bias point of some electronic components without disturbing other components. The bias tee is a diplexer.The low-frequency port is used to set the bias; the high-frequency port passes the radio-frequency signals but blocks the biasing levels; the combined port connects to the device, which sees both the bias and RF.

In a post-Jan. 6, 2021, America, where election deniers currently hold office across the U.S. as well as here in California, the roll of secretary of state, a referee for election integrity, has ...
The Weber–Fechner laws are two related scientific laws in the field of psychophysics, known as Weber's law and Fechner's law. Both relate to human perception, more specifically the relation between the actual change in a physical stimulus and the perceived change. This includes stimuli to all senses: vision, hearing, taste, touch, and smell.
