The phase-field method is reviewed against its historical and theoretical background. Starting from Van der Waals considerations on the structure of interfaces in materials the concept of the phase-field method is developed along historical lines. Basic relations are summarized in a comprehensive way. Special emphasis is given to the multi-phase-field method with extension to elastic interactio...

Using ANSYS finite element (FE) package, a multi-physics simulation model based on finite element method (FEM) is introduced for the multi-layer switched reluctance motor (SRM) in the present paper. The simulation model is created totally in ANSYS parametric design language (APDL) as a parametric model usable for various conventional types of this motor and it is included electromagnetic, therm...

Effects of binary mixtures of ionic/nonionic (sodium dodecyl sulfate/2-heptanol or 1-decanol) and nonionic/nonionic surfactants (2-heptnol/1-decanol) on drop/interface coalescence of water drops in a continuous n-heptane phase were examined. The drop size reduced appreciably and the multi-step coalescence was suppressed finally as the concentration of each of the constituting components</em...

A CMOS LC-tank VCO and phase-shifting network are described for a direct-conversion receiver of IEEE 802.11a. The direct-conversion receiver is configured to have sub-harmonic mixing structure which requires multi-phase local oscillator (LO) signals spaced by 45°. A poly-phase filter with 3and 4-stage RC networks generates multi-phase LO signals whose amplitude imbalance is removed by cascaded ...
