With this method, it is possible to establish an approach without the arbitrary modulation commonly used in other methods. Different procedures are described as is the influence of the different parameters which appear in the analysis. Several numerical examples are also presented, and the effectiveness of Ohsaki's method is conf...
我们提出了an indirect transmission measurement-based spectrum estimation method,利用已知密度的幻影的 raw projection data 来恢复相应的有效光谱。该方法已经通过模拟数据和实验数据进行了评估。定量分析表明该方法可以很好地估计X射线光谱。进一步的测试表明,使用更多的模型光谱和多组分幻影或物体可以改善光谱估计。此外,...
Set one object to use the Welch-based spectral estimation technique with a Hann window. Set the other object to use the filter bank estimation. Specify a noisy sine wave input signal with four sinusoids at 0.16, 0.2, 0.205, and 0.25 cycles per sample. View the spectral estimate using the ...
To view other objects in the Estimation library, type help dsp in the MATLAB® command prompt, and click Estimation. Initialization Use the same source as in the previous section on using the spectrumAnalyzer to estimate the power spectrum. The input sine wave has two frequencies: one at ...
The proposed algorithm uses a joint utility and strategy estimation under QoS constraints to minimize the received intra- and inter-tier interference for femtocells (FCs) and reduce inter-tier interference from FCs to eNBs. Their algorithm utilizes RL techniques to simplify their problem formulation ...
most existing peptide identification tools employ an over-simplified model to simulate the peptide fragmentation process, leading to an inaccurate estimation of the ion intensities. Taking SEQUEST as an example, ally-ions are given a fixed intensity, regardless of the factors with substantial effects ...

Additionally, we investigated sources of error to explore opportunities for future improvement in phase correction estimation. Results 3D raster scans of phase corrected focal spots 3D hydrophone raster scans were acquired for five sets of phase corrections: no correction, straight ray tracing, InSightec...
Snapshot— During a simulation, use the Snapshot button to pause the visualization at an interesting point so you can take a screenshot of the Spectrum Analyzer window.Estimation Tab The Estimation tab contains these sections. Domain ––Select the domain of the input signal that you want to ...
If the differences are found not to be essential, it may be possible to use a general model of linac heads for the estimation of photoneutron spectra. During the verification of the PDD curves, the discrepancy between simulation and experiment did not exceed 4%, which we assumed was ...
