regression algorithm developed in this work, we demonstrate that the long-term frequency drift rate of the crystal oscillator clock is significantly reduced from 1.1 脳10~(-11) per day to 1.8脳10~(-13) per day, effectively making the crystal oscillator clock as stable as an Rb atomic clock...
1 The computational load vs. the number of observations in subset testing algorithm GNSS technology determines positions by measuring the time differences between different satellite clocks and the receiver clock. A low-cost GNSS receiver normally uses a crystal oscillator as its clock, and this ...

(or provide) a measurable parameter, such as a crystal oscillator to measure time, a magnetometer to measure magnetic field, an electrometer to measure electric field, an accelerometer to measure acceleration along a sensitive axis, and a gyroscope to measure rotation about a sensitive axis. ...
This type of laser consists of three major subsystems: 1) a CW, high-power 1064 nm Master-Oscillator-Power-Amplifier (MOPA) drive laser: 2) a second harmonic converter subsystem comprising, a first optical cavity containing a first non-linear crystal operating in the visible spectral region; ...
Driven Oscillator Observe how the oscillation of the AFM probe piezo actuator is transferred to the AFM cantilever depending on frequency and damping! AFM Principle, AFM Measurements, AFM Application Modes General information about the technique Atomic Force Microscopy (AFM), as well as information ...
Of course, the line intensity depends on the oscillator strength f (which is directly linked and thus equivalent to the transition rate). Wiese elected to compare the experimental data with theory, or rather, with the results of computations that could easily provide numbers for hundreds or ...
Germinario and Shang[91]and Jones and Germinario[92]also reported “honeybee” structures in their studies on air-oxidizedSHRPcore asphalts. These authors stated that these structures had a “liquid crystal quality based on comparison with AFM images that had been obtained for polymer liquid crys...
