A quartz crystal oscillator can be thought ofas a resonator connected across an amplifier considered asa nonlinear dipole the impedance of which depends on theamplitude of the current that flows through it. The non-linear amplifier resistance and reactance are obtained byusing a time domain electrical simulator like SPICE (Simu-lation Program with Integrated Circuit Emph...

The Cooper pair box qubit of a two-junction-SQUID configuration enables the readout of the qubit states by probing the effective Josephson inductance of the SQUID. This is realized by coupling the qubit to a high-Q tank circuit which induces a small alternating supercurrent in the SQUID loop. The effect of a small (but finite) geometrical inductance of the loop on the eigenstates of the system ...

the domain of the qur’an has been one of the issues which have raised various viewpoints among the muslim scholars, particularly in recent decades that it has been more widely welcomed due to the muslims increasing attention to their revealed book and their encountering with the views of other religions and schools. in this respect, three viewpoints can be clearly seen among the muslim thinkers...

ultrasound images suffer of multiplicative noise named speckle. different de-speckling algorithms run either in spatial domain or in transformed domain. in this paper, an adaptive filter in spatial domain according to assume the nakagami distribution as the statistic of log-compressed ultrasound images is used. for de-speckling in transformed domain, the non-sub sampled shearlet transform is us...

Background:to analyze the epidemiological behavior of malaria, in relation to armed con-flicts presented on Pacific coast Nariño (PCN).Methodology: there was a multi-group ecological study with secondary information sour-ce, frequency malaria (PCN) population, and relationship region, resulting from country’s internal conflict, 2003 2017, analyzed.Results: Armed conflict affects structure healt...

one of the common problems in reflective seismic records is the existence of coherent linear and random noises which cause covering of the most important parts of reflective signals; therefore, it is necessary to attenuate them by processing methods. several processing techniques have been devised for attenuation of coherent linear noises and linear radon or ?-? transform is a powerful techniqu...

The frequency difference between signal-under-test and reference signal in phase demodulation will affect the result of the actual phase noise measurement. In order to eliminate the effect, an algorithm for both eliminating the frequency difference and extracting the phase noise of the signal-under-test is presented. Simulation and experiment results show that this algorithm is effective. By us...
