A Java port of a high school physics computing project. The original source code was in Processing. Simulations include circular orbits around the sun, general orbits around the Earth and the Doppler effect. orbit physics-simulation processing-sketch doppler-effect Updated Sep 13, 2021 Java Ej...
Detect small frequency shifts of the Doppler effect. You need a tone generator that emits a constant frequency (for example 1000Hz). Enter this base frequency in the experiments setup and select a detection range in which you expect the Doppler shifted frequency (for example 10Hz). The experim...

The Doppler effect refers to the change in frequency of a wave source as a consequence of the relative motion between the source and an observer. Veselago theoretically predicted that materials with negative refractions can induce inverse Doppler effects. With the development of metamaterials, inverse...
作为月球背面探测器的一种有效的跟踪手段, 本文以SELENE为例, 系统性地给出了4程多普勒观测系统的组成、数据处理和应用方法、定轨和重力场解算结果, 并分析了天线相位特性和自旋对4程多普勒测量精度的影响及改正方法. 这些内容对月球背面探测器的跟踪、测控和数传系统的研发和应用提供了参考实例....
This effect has not been previously reported for either clinical or preclinical ultrasound systems. One possible explanation is that it is due to the frequency estimation at low sample volumes, which will be broadened because of the short length of the observation of the pulse. This would ...
The signal beam is sent against the moving object, which causes a frequency shift due to the Doppler effect. Finally, a measurement of the returned signal and the idler is performed. We propose for the protocol a multimode probe state that can be generated by a parametric downconverter. The...
However, there are drawbacks in using such approaches: (1) to compensate for the limited-bandwidth of the probe, the signals are usually deconvolved by the impulse response of the probe which may increase the effect of low frequency noise. (2) Model-based reconstruction algorithms have very ...

processing techniques that introduce an averaging effect that in turn could reduce the fHR accuracy and beat-to-beat variability74. For this reason, it was impossible to adopt cardiotocography as a reference signal in our dataset. Although these results justify the choice of PWD as reference ...
