Presented in this thesis is the investigation of the influence of the coupling method on the water hammer wave speed in coupled petroleum pipeline. Experiment is done to study the variation of rubber's modulus with pressure when its deformation is restricted in one direction. The average ...
In this lesson, you will see how the wavelength of a particular wave impacts the wave's speed in deep waters. You will also learn why this...
The Dawson method of the wave making resistance calculation is extended to the situation of the high\|speed surface ships with transom stern, taking into account the 0 hydrostatic pressure of the transom plate, the trim and sinkage. As examples, the wave making problem of two models of high...
This Note presents a probabilistic model of transient wave reflection at a fluid-solid interface. The configuration represents an ultrasonic experiment used for bone tissue evaluation. The parametric method is used to derive the probabilistic model for the mechanical parameters of the solid (bone); th...
This paper presents a calculational method for transorn ship on wavemaking resistance. The calculatedresults for math. hulls and a combatant ship are compared with published calculated data and with the tested datarespectively, and the comparison showed a good agreements.This method is also used for...
Density functional methods lack the clear systematic path of improvement that is depicted in Figure 3 for wave-function based electronic structure calculations, although a hierarchy of functional types is proposed by Perdew et al. [424]. Detailed assessments of functionals (e.g., [425, 426]) ...
Equation (2) requires a large number of Bloch wavefunctions to converge. Moreover, they all scale cubically with respect to the number of atoms in the system (Methods), which limits their scope of applications. In fact, we can leverage locality in real space to considerably speed up the ...
This algorithm gives full consideration to coupling influence between the traction networks (harmonic voltage), and the fundamental wave results are used as the final convergence condition, aiming to determine modulation characteristics and harmonic current characteristics of SPWMconverter for EMU based on ...
