MICROWAVE RAMSEY PATTERN IN A LASER PUMPED CESIUM BEAM. APPLICATION TO VELOCITY DISTRIBUTION AND 2nd ORDER DOPPLER-SHIFT IN FREQUENCY STANDARD
نویسنده
چکیده
Analysis of experimental microwave Xamsey patterns, obtained with a laser pumped cesium beam frequency standard, shows the cesium atoms velocities to follow a broad 14axwellian distribution. As a consequence, the estimate of the second-order D6ppler-shift and cavity 2hase-shift could be more accurately obtained with this device than with the classical cesium beam frequency standard .

Time-frequency Analysis of a Noisy Ultrasound Doppler Signal with a 2nd Figure Eight Kernel
Nonstationary ultrasound Doppler signals, those are changing with time and frequency simultaneously, are widely observed in biological and speech signals. A Cohen’s class timefrequency (TF) analysis can analyze nonstationary signals with high resolution in time and frequency at a same time. A time-frequency distribution (TFD) is largely affected by a kernel function. Thus, there is sometimes a ...
متن کاملComparing the Effects of Fatigue Caused by the Treadmill and Overground Running on the Pattern of Plantar Pressure Distribution
Purpose: This study aimed to compare the effects of fatigue due to overground and treadmill running on the plantar pressure distribution pattern. Methods: Twelve novice athletes (Mean±SD age=26.0±2.5 y, Mean±SD weight: 52.0±3.0 kg, Mean±SD height: 159.0±5.0 cm), without sports injuries over the past year, were selected. Overground and treadmill running created fatigue in the samples. Peak pla...

متن کاملWavelet and curvelet moments for image classification: Application to aggregate mixture grading
We show the potential for classifying images of mixtures of aggregate, based themselves on varying, albeit well-defined, sizes and shapes, in order to provide a far more effective approach compared to the classification of individual sizes and shapes. While a dominant (additive, stationary) Gaussian noise component in image data will ensure that wavelet coefficients are of Gaussian distribution...
