The red circles represent the third stage intensity gradient and shape optimization. The blue tracing represents the final 2000-point interpolation stage. Full size image Our study involves obtaining force-coupled ultrasound data on the left internal jugular veins of 27 healthy volunteers. The MIT ...

Theoretical IR spectra were obtained using Materials Studio. We performed the analysis using density functional theory with the Perdew–Burke–Ernzerhof generalized gradient approximation using the Cambridge Serial Total Energy Package code. A norm-conserving pseudopotential with a plane-wave cutoff energy o...
It is shown that the SSI method, introduced as a fixed point method in (Mikyška and Firoozabadi, 2011), corresponds to a modified gradient step in an unconstrained minimization of the Helmholtz free energy with respect to mole numbers. Except for these extensions from conventional NPT flash ...
To handle the sharp change of the gradient in the regions near the shock or the solid wall, the convective flux is limited using high-resolution schemes such as the total variation diminishing (TVD) or the normalized variable diagram (NVD) scheme. The flux limiters are determined from the ...

Wilcox k-ω model [44] improves the simulation of a low Reynolds number flow near the boundary layer, which can improve the applicability of the model and predict the flow separation phenomenon with reverse pressure gradient accurately. The Wilcox k-ω model is very sensitive for the ω value...
Eventually, as in Section 3.1, there are linear increases in the EF over the inflation pressure, whereby the gradient depends to a large extent on the applied force and its direction. Since it may seem implausible at first that higher tire inflation pressure leads to higher emissions, the ...
Shear stresses and a gradient in the mean pressure in a body that is being compressed introduce some uncertainty into the experimentally determined values of high pressure in a solid; in this case high pressure is said to be quasi-hydrostatic. The smaller the shear stress in comparison with the...
