This paper presents an analysis of stability and resolution analysis of broadband (passive or active) array imaging in the Rician fading media. The main theoretical result is the stability condition where is the Rician factor, is the effective number of incoherent frequencies, is the effective numbe...
Atomic clocks are vital in a wide array of technologies and experiments, including tests of fundamental physics1. Clocks operating at optical frequencies have now demonstrated fractional stability and reproducibility at the 10−18 level, two orders of magnitude beyond their microwave predecessors2. Fr...
Step 3:Press "Ctrl+Shift+Enter" to apply the array formula. Excel will generate frequency counts for each bin. result This method is excellent for straightforward frequency tables, especially for beginners. Pressing Ctrl+Shift+Enter takes a bit to get used to, but it's worth it. Method 3:...
In situ radio-frequency heating (ISRFH) was successfully applied during remediation of a former petrol station. Using a three-electrode array in combination with extraction wells for soil vapor extraction (SVE), pollution consisting mainly of benzene, toluene, ethylbenzene, xylenes, and mineral oil ...
While multiple comb-based measurement techniques have been explored for molecular spectroscopy, such as comb-assisted Fourier transform infrared spectroscopy (FTIR)147 and virtually imaged-phased-array (VIPA)7, the most notable has been DCS139. Dual-comb spectroscopy, which was first demonstrated in ...
Delivery mode shapes the acquisition and structure of the initial microbiota across multiple body habitats in newborns Upon delivery, the neonate is exposed for the first time to a wide array of microbes from a variety of sources, including maternal bacteria. Although prior... MG Dominguez-Bello,...
The output array was a (210 × 1) array corresponding to the pest damage level based on the ratio of damaged area after final germination to the entire seed. To achieve optimal results for the predictive model, parameter tuning is crucial. In this regard, we utilize a reinforcement ...
Science with the Square Kilometre Array P.N.Wilkinson, ...T. JosephW. Lazio, inNew Astronomy Reviews, 2004 Technologies that must be developed to realize the SKA include: (i) wider bandwidth radio frequency receivers and their direct integration into antennas; (ii) low-cost manufacturing of ...
The Frequency Diverse Array (FDA) has a beampattern depending on both range and azimuth so it has great potential in active sensing applications. However, the range and azimuth is coupling in FDA. Especially in multiple target scenario, the existing methods suffer from problems such as coupling ...
The combustion of candles exhibits a variety of dynamical behaviors. Binding several candles together will result in flickering of candle flames, which is generally described as a nonlinear oscillator. The impact on the frequency of the flame by several
