Recently electronic tap-changer has received more attention due to its quick response, better performance and simpler maintenance compared to the mechanical tap-changer. This paper presents the capability of the distribution transformer equipped with an electronic tap-changer for improving power quality. At this end, the analytical computation for determining the compensating limit of electroni...

The filter bank multicarrier modulation based on offset quadrature amplitude modulation (FBMC/OQAM) is being considered as an eligible technology for future wireless communications. However, the orthogonality may be destroyed in the presence of multipath fading, and thus, the demodulated data may be affected by inter-symbol and inter-carrier interference. To restore the orthogonality, it is dee...

This contribution describes some specifics of VDSL performance in the presence of bridged taps. It is shown that the effect of a bridged tap depends on both the length and allocation of the bridged tap due to dominating of FEXT. As a result, bridged taps affect the opposite transmission directions differently and usually the upstream performance is degraded much more regardless of the applied V...

This paper presents new equipment to investigate workers’ time activity patterns (TAP) in workenvironment. A real-time chemical sensor coupled with a data logger comprises the newelectronic time activity recorder (ETAR). TAP data obtained from traditional workers’ recalledquestionnaires, working schedule of the plant, and ETAR were compared with the goldenreference, direct obser...

Dr. Greg Hinson is in the minority. He's among the meager 13 percent of physicians in solo practice who use electronic medical records, according to a recent Commonwealth Fund survey. But Hinson is comfortable being apart from the madding crowd. He knew electronic record keeping would be the ticket to efficiencies in his practice so he traded in his hodgepodge of inadequate record-keeping techn...

The second generation of Very-High Speed Digital Subscriber Lines (VDSL2) represents a modern high-speed solution for present last-mile access networks. However, the transmission performance of VDSL2 lines is heavily dependent on the real conditions of symmetrical pairs and quads in local metallic lines and cables. One of the frequent elements in metallic access networks, which can negatively i...

However, the high market penetration of smart cards does not nec...
