Studying the operation of MOSFET RC-phase shift oscillator under different environmental conditions

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Silk Persian Carpet under Loading in Different Environmental Conditions

In this research, an apparatus was designed and constructed in order to simulate the storage behavior of hand-woven carpet under different environmental conditions. Silk hand-woven carpet (“Gom”) with 115×75 cm dimensions and 102×97 knot per 10 cm was selected and then inserted into the packing simulator with two different laying configurations including flat and folded....

Geometric Phase Shift in a Neural Oscillator

This paper studies the eeect of slow cyclic variation of parameters on the phase of the oscillating Morris-Lecar model. In chemical oscillators it is known that a phase shift, called the geometric phase shift, is observed upon return to an initial point in parameter space. We nd geometric phase shifts for a two-parameter variation in the Morris-Lecar model. As with the chemical oscillator, the ...

Phase Shift Oscillator Circuit Using Op-amp

The conventional sine wave oscillator circuits use phase shifting techniques that RC phase shift oscillator using op-amp in inverting amplifier introduces. Figure show a RC phase shift oscillator using Op-Amp with gain 5(Vo/Vi). My assumption : Circuit is generating a sine wave with a peak to peak voltage of 10v. Voltage stability, specifically the lack of, when using a resister divider is the ...
