units around the crack tip when carrying finite element analysis was given respectively,and it was indicated that the mechanical influence on calculation re-sult by mechanical model should be taken into consideration when selecting the unit size of crack tip for the quarter node displacement formula....
The maximum vertical deflection is compared with the static deflection at the corresponding point due to the weight of the truck to find the impact factor. The impact factor so calculated is compared with the AASHTO formula impact factor. The study shows that the AASHTO formula underestimates the...
The profit margin formula simply takes the formula for profit and divides it by the revenue. The profit margin formula is:2 ((Sales - Total Expenses) ÷ Revenue) x 100 Gross Profit Margin This margin compares revenue to variable costs. It tells you how much profit each product creates...
The cross section for ionization from the vibrational level v″ of the neutral molecule to a vibrational level v′ in the ionized molecule is given by the Franck–Condon factor (FCF) which is equal to the square of the overlap integral between the respective vibrational wavefunctions, i.e. ...
Total energy production was not included for this calculation because most of the resource use efficiency indicators were based on total energy production already. This performance index was calculated separately for polder and non-polder households. The sample size, sample to variable ratio, and ...
This group of studies included only a few feature selection techniques mostly filter methods as well as accuracy factor, as indicated in Table 1. However, in this study, sixteen feature selection methods in three groups filters, wrapper, and evolutionary were studied and their impact on all fact...
After combining the two models, a complete reconstruction model of vehicle impact speed calculation is developed. Finally, in order to demonstrate the validity of the model, ten real-world accidents are chosen to compare the results. Access through your organization Check access to the full text ...
and the reduced supply and sedimentary reflux of Al3+ions and organic matter. The latter controls local redox restrictions (semi-confined micromilieu vs redoxcline) that predetermine the availability and the speciation of Fe (Fe2+vs Fe3+), which is the rate-determining factor for glauconite for...
The reason for this could be the use of empirical values for all pixels of the same class, and the kriging interpolation in the meteorological factor calculation, which could act as a smoothing process, ignoring the diversity of the different locations. The monthly results of the CASA model ...
The water vapor is a key external impact factor of fog-haze conversion. For the RH within the range of 80%–95%, a certain value is given. By analyzing the correlation between the TCWV and VIS in the two ranges of 80% to the given RH value and the given RH value to 95%, the ...
