Several models concemmg the senslhvlty of capaclhve pressure sensors have been presented m the past Modellmg of condenser nucrophones, which can be constdered to be a specml type of capacltlve pressure sensor, usually reqmres a more comphcated analysis of the senstttvlly, because they have a strong electnc field m the atr gap It IS found that tbe mechamcal sensltlvlty of condenser rmcrophones ~...

Switchable DNA condensers based on β-cyclodextrin derivates bearing cationic imidazolium moieties and hydrolysable ester linkages were synthesized, showing base-responsive or enzyme-responsive switchable DNA condensation ability under physiological conditions.

Many distributed energy (DE) resources are near load centers and equipped with power electronics converters to interface with the grid, therefore it is feasible for DE to provide ancillary services such as voltage regulation, nonactive power compensation, and power factor correction. A synchronous condenser and a microturbine with an inverter interface are implemented in parallel in a distribut...

Preface In the scope of my studies at the Technical University of Denmark (DTU) in the Engineering Acoustics master program, I have done my final project about modelling distortion in condenser microphones. This subject was originally proposed by Brüel & Kjaer Sound & Vibration Measurement A/S (B&K) under the title Distortion process in condenser microphones. In February 2009 I have started my ...

There is a demand for reduced power consumption in the vapor compression refrigeration cycle. Coefficient of performance of window-air conditioners considerably decreases and power consumption increases under very hot conditions. These problems have encouragecl studies aimed at improving the performance of window-air-conditioners by enhancing the heat transfer rate in the condenser. In this ar...

respectively. The full wave duration is approximately five times the rising phase, which has to be considered if repetitive stimulation is used. In the latter case the ordinary contact key K has to be replaced by an automatic commutator. v FIG. 1 portional to, changes in the plate current of AT; its shape, therefore, is that of the potential wave between x and y. For double condenser discharges...

Experimental investigation on the performance of dual-evaporator refrigeration system with an ejector has been carried out In this study, HFC-134a is chosen as a working fluid. Test setup is composed of compressor, condenser, expansion valves, two evaporators, and ejector which is installed between two evaporators. The condenser and two evaporators are made as concentric counter-flow type heat ...

In the previous article in this series, the charge and discharge of a condenser via a resistance was considered. It was assumed that ample time was available for the charge or discharge to take place. The product (capacity in microfarads x resistance in megohms) has the dimensions of a time in seconds, and is known as the "timeconstant" of the circuit. After charging for a period equal to one t...
