range and the location of artificial reflectors or intermediate values at these points. A similar fictitious sources inherent in discrete wave economy can be obtained using the itrerative reflection and transmission coefficient relations number techniques. The number and spacing of wave numbers in wave number integration schemes are of Kennett. Kamel and Felsen (1981) presented a hybrid determi...

INTRODUCTION The reflection and refraction of horizontally polarized shear (SH) waves by a frictional contact interface that can slip has been studied by the present authors [l-3] and Miller [4-6]. If the solids are sheared, the localized slip induced by the waves is more pronounced in one direction than in the other, which leads to the interesting phenomenon of the solids creeping with respect...

Ultrasonic guided wave inspection is much more efficient than traditional point-bypoint examination. Guided waves can propagate over long distances from a single position, and therefore is a good method of evaluating thickness degradation, especially for large-area structures such as pipes and vessels. In this paper, guided wave thickness measurement potential is studied utilizing a peak freque...

This paper reviews recent work, much of it unpub~shed, on the effects of anisotropy on seismic waves, and lays the theoretical background for some of the other papers in this number of the Geophysical Journal. The propagation of both body and surface waves in anisotropic media is fundamentally different from their propagation in isotropic media, although the differences in behaviour may be comp...

Let SH,K = {SH,K(t), t ? 0} be a d?dimensional sub-bifractional Brownian motion with indices H (0, 1) and K (0,1]. Assuming d 2, as HKd < 1, we mainly prove that the renormalized self-intersection local time t0 s0 ?(SH,K(s) SH,K(r))drds E [?t0 ?s0 SH,K(r))drds] exists in L2, where ?(x) is Dirac delta function for x Rd.

V 2 A + C 2 s + V ∆t/∆x < 1 is satisfied, where VA is the Alfvén wave speed, Cs is the sound wave speed, and V is the flow speed. Unconditional stability for sound and Alfvén waves with arbitrary time step ∆t is achieved by adding a semi-implicit term to the momentum equation. However, the flow CFL condition V∆t/∆x <must still be satisfied. The resistivity and viscosity are advanced implicitly ...

Nonlinear Optical Spectroscopy of Solid/Solid Interfaces Mohsen S. Yeganeh Arjun G. Yodh Three-wave mixing (3WM) spectroscopy is an exciting and relatively unexplored probe of buried solid interfaces. It possesses long penetration depths characteristic of most optical methods and intrinsic interface specificity characteristic of second-order optical processes. In this thesis we present frequenc...

New ab initio potential energy surfaces for the (2)Pi ground electronic state of the Ar-SH complex are presented, calculated at the RCCSD(T)/aug-cc-pV5Z level. Weakly bound rotation-vibration levels are calculated using coupled-channel methods that properly account for the coupling between the two electronic states. The resulting wave functions are analyzed and a new adiabatic approximation inc...

Abstract Social housing (SH) development is, in general, triggered by policies and regulations, which stimulate interventions, create financing mechanisms, designate agents conducive to retrofit processes. European directives for energy efficiency the recent call a ‘retrofit wave’ have an evident influence. In Brazil, delivery management of SH are based on public offer units their immediate own...

Compared with Global Atmosphere 6 (GA6) of the UK Met Office Unified Model (UM), dry bias over Indian monsoon region in 7 (GA7) is significantly reduced. However, physical processes controlling how this reduced India influences rainfall teleconnections extratropics remain unclear. Thus, study, we use Rossby wave tracing a horizontally nonuniform background flow to investigate improved simulatio...
