Chapter 28 Alternating Current Circuits
... Equation 28.7 gives the effective value of the voltage in an AC circuit. The effective voltage is a constant value of the voltage that produces the same effect as the alternating voltage. Thus, the constantly changing alternating voltage is described in terms of the single valued, constant effective ...

A new electro-osmotic pump based on silica monoliths
... Electro-osmosis is a common technique for pumping fluids. If the wall of capillary or micro-channel has electric charges, as most surfaces do, an electric double layer of counter ions will spontaneously form at the wall [24]. In the case of a silica monolith, the main source of surface charges comes ...

Detection of Multiple Electrical Sources in Tissue Using Ultrasound
... The dimensions along cross-section are important to the detected AE signal. Dimensional analysis over lateral width and thickness of tissue slab can be done by simulation. When the lateral width of cross-section changes from 0.025mm to is held constant (the phase does not change, figure 7(b)), and t ...

Current control by ECCD for W7-X
... changes of the bootstrap current by applying counter-ECCD, i.e. the non-inductive current of the same value, but in the opposite direction. The usual feedback control scheme seems to be unfeasible because (i) there is no means to measure the bootstrap current density profile and (ii) measurements of ...
