General expression for the peak asymmetry factor in amplitude spectraAn expression for 0305-4470/30/12/020/img2, where 0305-4470/30/12/020/img3 is presented.doi:10.1007/BF02158954V. V. SamedovKluwer Academic Publishers-Plenum PublishersMeasurement Techniques...
The peak asymmetry was determined by two theoretical calculations: the asymmetry factor by elution peak analysis and skewness with moment analysis. The sharpness was estimated by the fourth central moment. In this work, the most acceptable skewness was calculated when the pore size was 300 . The ...

In order to test whether subsequent principal components correlate and correct for causes of low-energy tailing, the photopeak asymmetry is measured after application of additional principal component corrections. At the risk of over-fitting to in-sample data, corrections determined from the first 200...
As we later show, amplitude asymmetry might be less than ideal in identifying such dynamics. The need to capture and quantify possible asymmetries between the local maxima and minima of time series is not just inherent in neurobiological processes. Let us consider the time evolution of some ...
The peak velocity vectors also provide a qualitative overview of the tidal asymmetry [32], and the tidal flow appears to be largely ebb-dominant (peak currents directed northwest) in Westray Firth, and flood-dominant (peak currents directed southeast) in Stronsay Firth.7 Where these two Firths...
The factor Г(1-α) included by Doniach-Sunjic [4] in their expression for the photoelectron yield is simply a constant for a given α and therefore not included in the profile below, nevertheless this factor becomes increasingly large as the degree of asymmetry increases and, is a good ...
The easy collision between the curing agents was the main factor for the higher ∆HRubber value of unfilled SBR system than different HNT filled SBR systems. The value of ∆HRubber had the tendency to decrease with increasing the amount of immobilized rubber chains in SBR composites. Thus,...
“This leads to the following asymmetry in climate policy. The scale of the effect must be demonstrated to be large enough to have impact. Once this is shown, and it has been, the burden of proof of absence of harm is on those who would deny it. It is the degree of opacity and unc...
The Joint Operating Environment has spoken thoroughly about the asymmetric application of power by potential enemies against U.S. military forces. There is also an asymmetry with respect to the defense spending of the United States and its potential opponents, particula...
