We investigate gate voltage dependence of electrical readout noise in high-speed rf reflectometry using gallium arsenide quantum dots. The fast Fourier transform spectrum from the real time measurement reflects build-in device and circuit including resonator amplifier. separate their spectral components by model analysis. Detail flicker is investigated compared to charge sensor sensitivity. poi...

Visual function is usually considered to be normal in papilledema. We report previously undescribed abnormalities in the electroretinograms (ERG) and visual evoked potentials (VEP) of two patients with chronic papilledema. The steady-state latencies of the ERG and VEP were calculated using time-difference analysis. The ERG was abnormal under both scotopic (slow) and photopic (fast) flicker cond...

The human visual sensitivity to sinusoidal flickering light is generally band-pass tuned to temporal frequency, probably due to retinal physiological properties consist of low-pass and following high-pass filtering processes. It is also shown that the temporal sensitivity of visual cortex has a band-pass shape. Meanwhile, for the flickering lights with two or more frequency components, flicker ...

A flicker sensitivity test based on measuring modulation thresholds for light varying sinusoidally with time around two mean scotopic luminances was performed on 21 female patients heterozygous for X-linked retinitis pigmentosa and 22 normal observers. The patients required, on average, 1.5 times the normal modulation to detect flicker over the whole frequency range where thresholds could be me...

The research presented in this paper focuses on the impacts of fast-charging stations three power quality phenomena, namely voltage magnitude variations, unbalance, and fluctuation. Markov Chain Monte Carlo is proposed to estimate energy requirements each station when it utilized charge electric vehicles, considering their sto-chastic parameters such as battery capacities, state-of-charge level...

It is well known that the output power from small wind turbines (SWTs) fluctuates noticeably more when compared to other types of dispersed generators, such as residential photovoltaic (PV) generation systems. Thus, degradation voltage quality, flicker emissions, numerous SWTs are installed in a low-voltage distribution system particular concern. Nevertheless, practical examples emissions facil...

In this paper, a new analytical estimator for light flicker in frequency domain, which is able to take into account also the frequency components neglected by the classical methods proposed in literature, is proposed. The analytical solutions proposed apply for any generic stationary signal affected by interharmonic distortion. The light flicker analytical estimator proposed is applied to numer...

In patch-clamped membranes from neonatal rat cardiocytes, elementary Na+ currents were recorded at 19 degrees C for study of the inhibitory influence of several antiarrhythmic drugs including lidocaine, diprafenone, propafenone, and prajmalium on DPI-modified cardiac Na+ channels. Diprafenone (20 mumol/l) and lidocaine (300 mumol/l) induced a voltage- and time-dependent block of reconstructed m...

Herein, a novel wind power grid-connection system based on inductive filtering is proposed to improve compatibility, and implemented in 50-MW real system. First, the topology wiring configuration of are discussed. Thereafter, an equivalent circuit mathematical model established reveal characteristics resonance damping mechanism Finally, farm-based experimental study, which conducted validate ef...

this paper proposes a low voltage (±0.55v supply voltage) low power (44.65µw) high common mode rejection ratio (cmrr) differential amplifier (d.a.) with rail to rail input common mode range (icmr), constant transconductance (gm) and enhanced frequency performance. its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...
