An algorithm for the estimation of the electric resistance for self-sensing magnetic levitation systems is presented. The development of this novel estimation algorithm is based on the position estimator proposed in Glück et al. (2010). Based on the mathematical model of the considered magnetic levitation system, the main ideas of the position estimation algorithm are summarized. A detailed ana...

The phase composition and electrical transport properties of Cu powder obtained by electric spark dispersion and the pellets manufactured from this powder were studied by X-ray phase analysis and electric resistance measurements. The compacted powders were annealed in pure Ar atmosphere. It was shown that electrical resistance of the compacted Cu specimens essentially depends on the annealing t...

The capillary electrochromatography (CEC) takes an important position in the separation sciences [1-8], and its further development will contribute to the analytical chemistry field. Therefore the study of the electrochromatographic behavior is very important. The key factor of CEC is the electric field applied along a capillary column. In general, the role of the applied electric field in CEC ...

the basis of the ohmic heating process is the transmission of alternating electric current through multi-phase solutions that is followed by heat generation due to particle resistance to the transmitted electric current. throughout the present study, simultaneous transfer of heat and electricity was modeled in a two-phase system of solid-liquid food to investigate the critical factors affecting...

OBJECTIVE To assess the role claudin-5, an endothelial cell (EC) tight junction protein, plays in establishing basal permeability levels in humans by comparing claudin-5 expression levels in situ and analyzing junctional organization and function in 2 widely used models of cultured ECs, namely human dermal microvascular (HDM)ECs and human umbilical vein (HUV)ECs. METHODS AND RESULTS By immuno...
