Wave elevation

Cardiovascular manifestations include hypertension and cardiac arrhythmias (e.g., heart block, atrial flutter, paroxysmal atrial tachycardia, ventricular fibrillation, and digitalis-induced arrhythmias). In severe hypokalemia (serum concentration <2.5 mEq/L), ECG effects include ST-segment depression or flattening, T-wave inversion, and U-wave elevation. 

Attempts to explore this complicated interaction and to model the response of the eddy viscosity and turbulent shear stresses to the time variation of pressure gradients in turbulent air flow over a solid wavy surface have been made by Thorsness et al. [85] and Abrams and Hanratty [89]. Large variations of the amplitude and phase angle of the surface shear stress with the dimensionless wave number were predicted (Figure 3). The analysis shows that the surface shear stress fluctuation is shifted upstream with respect to the wave elevation and the phase shift varies in the range of 0-80° in comparison to the constant phase shift predicted by Benjamin [84],... 

Equations 32 show that the amplitude of the interfacial shear includes two terms, one of which evolves from the quasi-steady part while the other, which stems from the dynamic term. is proportional to the wave number, k. The phase shift of the interfacial shear with respect to the wave elevation (for C, = 0) evolves due to the... 

Twenty-seven capacitance wave gages were used to measure surface wave elevations (Fig. 39.12). The first four gages were located parallel to the wavemaker to measure incident wave conditions. The same procedure for locating the incident gages as described for previous experiments was followed. A measurement grid of...

Gages A, B, C, and D are located on the circumference of a circle having a radius R and gage E is located at the center of the circle. The water surface elevation is derived from gage E, while the orthogonal slopes dq/dx and dq/dy are derived from the wave elevation differences between gages A and C and B and D, respectively. 

Wave breaking may occur at points A and B where t(t) < 0. Here and hereafter, overdot denotes differentiation with respect to time t. At point A where t(t) > 0 and when t) < -Kg (K 0.4 to 0.5 ) the breaking wave elevation is given by... 

That Is, when the wave breaks at A, the local wave elevation is reduced according to the ratio of Kg and the local acceleration of the ideal wave By the same token, at point B, wheret (t) < 0 and whereC (t) < Kg, the breaking wave elevation is given by... 

From Eq (6), it is seen that the breaking wave elevation C, is a non-...
