damping of a full-scale cable with a pair of passive–on magnetorheological (mr) dampers was tested. a cable of 215.58m long with the first mode frequency of 0.658hz was tensioned horizontally in cable prefabrication factory. two mr dampers were attached to the cable in an angle in the plane perpendicularly to the cable axis in 5m length from the cable anchorage. the applied voltage level was 0v...

Excitatory postsynaptic currents (EPSCs), miniature excitatory postsynaptic currents (MEPSCs), and acetylcholine-induced current fluctuations (noise) have been studied in voltage-clamped bullfrog parasympathetic ganglion cells of the atrial septum. EPSCs were also recorded from voltage-clamped sympathetic B cells and, in general, it was found that the basic properties of the EPSCs are similar i...

Excitatory postsynaptic currents (EPSCs) have been studied in voltage-clamped bullfrog sympathetic ganglion B cells. The EPSC was small, rose to a peak within 1-3 ms, and then decayed exponentially over most of its time-course. For 36 cells at --50 mV (21-23 degrees C), peak EPSC size was --6.5 +/- 3.5 nA (mean +/- SD), and the mean decay time constant tau was 5.3 +/- 0.9 ms. tau showed a small...

The corona-charged fibrous electrets are dielectric materials exhibiting quasi-permanent electrical charge imparted by means of corona discharge process. The electrical charge in the electret fibrous materials has been utilized to capture hazardous particles from complex air streams. Air filters of this kind are widely used as respirators and face masks in personal protective equipments, dust c...

power system blackouts have become a serious problem for electric utilities especially in recent years. different forms of system instability have emerged in recent blackouts, such as voltage instability and frequency instability. to counteract each form of system instability, special algorithms have been designed in the protection system, e.g. under frequency load shedding (ufls) and under vol...

Voltage Decay In article number 2213260, Zhaoping Liu, Quanbing Bao Qiu, and co-workers review the mechanism of voltage decay generation in Li-rich layered oxides, which is caused by a combination phase transition, microscopic defects, oxygen redox. The also provides critical insight into root decay, as well predictions for potential solutions.

Although Li-rich layered oxides (Li1+xNiyCozMn1-x-y-zO2 > 250 mAh g(-1)) are attractive electrode materials providing energy densities more than 15% higher than today's commercial Li-ion cells, they suffer from voltage decay on cycling. To elucidate the origin of this phenomenon, we employ chemical substitution in structurally related Li2RuO3 compounds. Li-rich layered Li2Ru1-yTiyO3 phases with...

A fast-response and wide-view fringe-field switching LCD using patterned common electrodes is proposed. By applying a restoring pulse voltage on common electrodes, LC decay process is expedited. The GTG decay time can be reduced by >7X, depending on the applied erasing voltage. This new mode also preserves the wide-view characteristics as the conventional FFS mode. It is attractive for reducing...

This study conducts a qualitative comparison between two methods for detecting side reactions - the voltage hold and decay using high precision coulometry (HPC) tester. The measurements were conducted with Si-G/NMC811 commercial cells three different temperatures four states of charge (SoC) in order to determine temperature dependency reactions. Here, we show that deliver comparable results whe...
