Accurate detection of weak periodic signals within noise and possibility of secure messaging have made Duffing oscillator (DO) highly important in the field of communication. Investigation on the properties of DO is thus ardently sought for. An elegant approach to accomplish the same is to fabricate electronic circuit simulating DO non-linear equation and to study the effect of input signal amp...

in this research, the efficiency of the comminution circuit as well as the efficiency of size classification equipment of the concentrator plant 2 of sarcheshmeh copper complex was studied. the comminution circuit of this plant includes one sag mill in a closed circuit with a vibrating screen and one ball mill with a size classification system of hydrocyclone. the goal of this work was to calcu...

A prompt report for the commissioning run of the longbaseline neutrino oscillation experiments will be presented. Improvement of the KEK-PS main ring has been performed for recent years in order to prepare the long-baseline neutrino oscillation experiment. Intensity upgrade studies and the hard ware improvements result in a factor of 50% increase in the beam intensity to 5-6 × 10 ppp up to now....

The RHIC injection kicker is a pulsed transmission line kicker, consisting of 15 ferrite sections and 14 ceramic sections. The length of the kicker is 1.1 m and there are 4 such units in each ring. Figure 1 shows the kicker cross section with the outer conductor, C-shaped ferrite, inner conductor and the ceramic beam pipe [1]. The design characteristic impedance of the transmission line kicker ...

Effects of temperature on electrical parameters of polysilicon solar cells, fabricated using the phosphorous spin-on diffusion technique, have been studied. The current density–voltagecharacteristics of polycrystalline silicon solar cells were measured in dark at different temperaturelevels. For this purpose, a diode equivalent model was used to obtain saturation current densi...
