We present an approach to calculate scalar and tensor gravity utilizing the massively parallel architecture of consumer graphics cards. Our parametrization is based on rectilinear blocks with constant density within each blocks. This type of parametrization is well suited for inversion of gravity data or joint inversion with other datasets, but requires the calculation of a large number of mode...

To determine if the height of a basketball shoe alters the maximal inversion and eversion moment that can be actively resisted by the ankle in the frontal plane, we tested 20 healthy, young adult men with no recent ankle injuries. Subjects underwent unipedal functional ankle strength testing under weightbearing conditions at 0 degrees, 16 degrees, and 32 degrees of ankle plantar flexion using a...

We analyze seismic waves excited by small Strombolian explosions to understand the source process of volcanic explosions. deployed five broadband seismometers at only 100–300 m away from active craters Stromboli volcano, Italy. Moment tensor inversion entire signals in 0.05–0.2 Hz band locates a depth 170 and 150–200 west/southwest crater where acoustic are excited. Contrary, sources 0.2–0.5 0....

An algorithm to generate samples with approximate first-, second-, and third-order moments is presented extending the Cholesky matrix decomposition to a Cholesky tensor decomposition of an arbitrary order. The tensor decomposition of the first-, second-, and third-order objective moments generates a non-linear system of equations. The algorithm solves these equations by numerical methods. The r...

We consider the problem of learning associative mixtures for classification and regression problems, where the output is modeled as a mixture of conditional distributions, conditioned on the input. In contrast to approaches such as expectation maximization (EM) or variational Bayes, which can get stuck in bad local optima, we present a tensor decomposition method which is guaranteed to correctl...

It has been suggested that the inertia tensor governs many instances of haptic perception. However, the evidence is inconclusive because other candidate mechanical parameters (i.e., invariants) were not or were insufficiently controlled for in pertinent experiments. By independently varying all candidate mechanical parameters, the authors were able to test the role of the inertia tensor relativ...

A (microscopic) static elastoplastic field theory of dislocations with moment stress is considered. The relationship between the moment stress and the Nye tensor is discussed and used for the dislocation Lagrangian. We discuss the stress field of a screw dislocation which is modified in the core region due to the appearance of moment stress.

Understanding a tsunami source and its impact is vital to assess hazard. Thanks the efforts of survey teams, high-quality run-up data exist for contemporary events. Still, it has not been widely used infer mainly due computational burden forward model. In this study, we propose TRRF-INV (Tsunami Run-up Response Function-based INVersion) model that can provide probabilistic estimates near-field ...

2014 We predict in the case of FeCl2 which is an uniaxial antiferromagnet for T ~ TN (~ 25 K), that one can modify the Fe+2 ions crystalline field symmetry by applying a mechanical stress and hence modify the moment orientation of these ions. We give as function of the crystalline field variation 03B4W, an expression for the components of the tensor which relates the moment variation of each io...
