In this paper we describe an apparent paradox concerning a moving plate capacitor driven by thermal noise from a resistor. The plates are attracted together, but a demon restores the plates of the capacitor to their original position when the voltage across the capacitor is small-hence only small forces are present for the demon to work against. The demon has to work harder than this to avoid t...

A novel two-split capacitor (T-SC) array structure for Successive Approximation Register (SAR) analog-to-digital converter (ADC) is proposed. When used as digital –to-analog converter (DAC), this circuit reduced the chip area by 27.7% in comparing with the conventional Split Capacitor (SC) at resolution=14. The area reduction effect can be more significant with the increasing resolution of ADC....

Conventional switched capacitor converters have an inherent drawback that their efficiency decreases as the output current increases. This inherent drawback is due to a periodical forced charging and discharging operation in the internal switched capacitors accompanied by a large capacitor current. Their efficiency can not be increased by decreasing its internal resistance. As a result, convent...

Micromachined gyroscope always contains two groups of capacitors, one is the driving capacitor, which is used to drive the micromachined gyroscope, to make sure the gyroscope could oscillate along the driving direction. The other is so called the sensing capacitor, which used to detect the displacement along the sensing direction, in order to detect the input angle velocity. Since there are som...

INTRODUCTION Passengers experiencing fear of flying can threaten the safety of a flight, its passengers, and crew. In the present study we investigated the effect of different flying histories on the nature and treatment of fear of flying and attempted to determine the following: 1) the prevalence of different flying histories in a sample of self-referred flying phobics; 2) the demographic and ...

Honeybee, a small -although powerful- creature moves from one place to another to make an elixir, which cures different diseases. To make one kilogram of honey the small creature has to carry 150000 pieces of pollen and suck the sap of ten million flowers. Both honey and the honeybee poison have been used in treating diseases for thousands of years. The product made by such tiny creatures has b...

Probability bias regarding threat-relevant outcomes has been demonstrated across anxiety disorders but has not been investigated in flying phobia. Individual temporal orientation (time perspective) may be hypothesised to influence estimates of negative outcomes occurring. The present study investigated whether probability bias could be demonstrated in flying phobia and whether probability estim...

Utilizing capacitor banks is very conventional in distribution network in order for local compensation of reactive power. This will be more important considering uncertainties including wind generation and loads uncertainty. Harmonics and non-linear loads are other challenges in power system which complicates the capacitor placement problem. Thus, uncertainty and network harmonics have been con...

The various optimal capacitor placement techniques on transmission and distributions lines for line losses reduction and enhancement of voltage stability in the power system network have been proposed so far in different papers. Optimal Capacitor placement is an optimization problem which has an objective to define the sizes and locations of capacitors to be installed. This paper focuses on the...

The electrical performance of Hybrid capacitors (US Patent 5,369,547) using high capacitance density electrochemical capacitor cathodes, electrolytic capacitor anodes and dielectric, and compatible electrolytes is strongly influenced by the nature of the electrolyte employed and the physical characteristics of the electrodes. Management of overall capacitor performance usually involves optimizi...
