Long-period surface-wave (R(1), G(1)), body-wave (S, SS, SSS), and ScS-reverberation data have been inverted to obtain anisotropic structures along seismic corridors that sample Australia and the western Pacific. These models support the proposal that the Lehmann discontinuity beneath stable continents represents a transition from an anisotropic lithosphere to a more isotropic material in the l...

In this paper, an upper bound approach is used to analyze the tube extrusion process through rotating conical dies with large mandrel radius. The material under deformation in the die and inside the container is divided to four deformation zones. A velocity field for each deformation zone is developed to evaluate the internal powers and the powers dissipated on all frictional and velocity disco...

The quasistatic inflation of a nonlinear viscoelastic spherical membrane by monotonically increasing pressure is considered. The deformation is assumed to be spherically symmetric. For the constitutive equation assumed, circumstances are shown to exist when the radius history must either have a jump discontinuity or bifurcate. A necessary condition for bifurcation and its dependence on material...

A system of equations modeling antiplane shear in a granular material is considered. The model includes the possibility of localization of strain, and the subsequent development of shear bands. This behavior is captured in our analysis of the Riemann initial value problem, in which an initial discontinuity propagates as a combination of moving waves and a stationary shear band. The analysis is ...

For convenience, let us rewrite v(x,y) as a function of three parameters v(dc,don, p): the compressed discontinuity dc, the oriented normalized discontinuity don, and the relative coordinates of the screen-space pixel in the projected light space p. For the parameters dc and p, the description given in the Section 3.1 of the paper is sufficient for this supplementary document. However, we need ...

The Strukov model was the phenomenological model that accompanied the announcement of the first recognised physical instantiation of the memristor and, as such, it has been widely used. This model described the motion of a boundary, w, between two types of inter-converting material, Roff and Ron, seemingly under a uniform field across the entire device. In fact, what was intended was a field wi...

This paper is partly born of an increasing sense of uncertainty about how to do syntax. Time was, we linguists had at our disposal a generally accepted arsenal of analytic devices to deal with a familiar range of constructions and phenomena. However, as the phenomena under study began to proliferate, so did the analyses. The increasingly baroque GB architecture began to collapse under the weigh...
