Our method are based on the Gümü's method for incident electrons. We have calculated the collisional and radiative stopping power and then found the total stopping power of targets. For collisional stopping power, we used Gümü's method for electrons but adapted it to the positrons. Tsai's...
of the third order PIMP,the fifth order PIMP is calculated by using power series,and the comparison among the PIMPs produced by different alumina is done.Numerical and measure results indicate that oxide's PIMP power level increases with the increase of input power,and increases with the ...
The mechanism of internal overvoltage in restoring the non-loaded long distance overhead line during the power system black-start process is analyzed,and the calculation model of overvoltage is established.The general software for simulation of power systems is applied to calculate power frequency ...
There are several considerations to take into account when calculating power, and this quiz/worksheet will help you test your understanding of the components of the calculation as well as its execution. Quiz & Worksheet Goals In these assessments you'll be tested on the following: ...
This feature recommendation is based on a sample of a data, so you should review the inputs used. You can change the selections to include only the columns you want the model to study. You can also select all the columns by selecting the checkbox next to the table name. 4. Name your...
The ball loads within the mills were measured by different methods proposed in the literature and power draw of each mill were calculated. The results showed that power draw of the cement mills could accurately be predicted by the method proposed in this study.关键词:...
The Linear and Self-Consistent Nonlinear Theory of the Electron Cyclotron Maser Instability In this paper the linear and nonlinear theory of the electron cyclotron maser instability is considered. The configuration used to study the maser instabil... P Sprangle,AT Drobot - 《IEEE Transactions on ...
Power analysis plays a pivotal role in a study plan, design, and conduction. The calculation of power is usually before any sample data have been collected, except possibly from a small pilot study. The precise estimation of the power may tell investigators how likely it is that a stat...
Correlation coefficient of 0.5381 (P < 0.01) was found between assumed ACDpo calculated according to the authors' equation and the actual ACDpo. On the basis of the results achieved in the study, the authors propose that surgeons develop their own regression equations for the calculation of ...
