摘要:The capillary rise phenomenon of the water in a cylindrical tube is investigated in arbitrary acceleration. The surface roughness of water comes from thermal energy. The critical radius of a water drop between surface tension and volume force is shown as a function of accele...

摘要:This paper proposes a new DAC BIST (digital-to-analog converter built-in self-test) structure using a resistor loop known as a DDEM ADC (deterministic dynamic element matching analog-to-digital converter). Methods for both switch reduction and switch effect reduction are proposed...

摘要:Power grids sustain modern society by supplying electricity and thus their stability is a crucial factor for our civilization. The dynamic stability of a power grid is usually quantified by the probability of its nodes’ recovery to phase synchronization of the alternating cu...

摘要:Abstract(#br)Electron velocity in a two-dimensional electron gas can be measured by Doppler shift. Thus, we construct the Doppler shift of light and apply it to the motion of electrons in a graphene sheet to estimate the electron velocity. Here, a laser beam with initial frequenc...
