Gaussian processes are a limit extension of neural networks. Standard Gaussian process techniques use a squared exponential covariance function. Here, the use of truncated covariances is proposed. Such cov-ariances have compact support. Their use speeds up matrix inversion and increases precision. Furthermore they allow the use of speedy, memory eecient Toeplitz inversion for high dimensional g...

Diagnostic and operational tasks in dental radiology often require three-dimensional information that is difficult or impossible to see in a projection image. A CT-scan provides the dentist with comprehensive three-dimensional data. However, often CT-scan is impractical and, instead, only a few projection radiographs with sparsely distributed projection directions are available. Statistical (Ba...

In the crystal structure of the title compound, C(40)H(26)N(4), mol-ecules reside on crystallographic centers of inversion and are linked via C-H⋯N inter-actions about inversion centers into one-dimensional chains: longer C-H⋯π(arene) inter-actions complete the inter-molecular inter-actions.

There is growing interest in developing a three-dimensional (3-D) inversion and imaging technique from a single borehole. This problem can be solved by using tensor (multi-component) induction welllogging – TIWL. This method was originally introduced to resolve formation anisotropy. However, it was demonstrated in several publications that the TIWL instrument has sensitivity to 3-D conductivity...

Time-lapse three-dimensional inversion of complex conductivity data using an active time constrained (ATC) approach" (2011).

The aim of the present study is to develop a submillimeter volumetric (three-dimensional) fluid-attenuated inversion recovery sequence at 7T. Implementation of the fluid-attenuated inversion recovery sequence is difficult as increased T(1) weighting from prolonged T(1) constants at 7T dominate the desired T(2) contrast and yield suboptimal signal-to-noise ratio. Magnetization preparation was us...

The Disproportionate Face Inversion Effect (DFIE), the finding that inversion disproportionately affects face recognition, provides a primary piece of evidence to suggest that faces are processed in a qualitatively different way to other visual stimuli (i.e., along configural as well as featural dimensions). However, when Loftus, Oberg and Dillon (2004; also Prince and Heathcote, 2009) examined...

Dynamic models of elastic structures are derived using approximations of linear three dimensional elasticity. A model for the three dimensional motion of a nonsymmetric structure that is of use for applications to health monitoring for buildings is obtained. The symmetric version of the model is validated using laboratory acceleration data. Narrow plate equations whose derivation is based on si...

An infinitely long hollow cylinder containing isotropic linear elastic material is considered under the effect of arbitrary boundary stress and thermal condition. The two-dimensional coupled thermoelastodynamic PDEs are specified based on equations of motion and energy equation, which are uncoupled using Nowacki potential functions. The Laplace integral transform and Bessel-Fourier series are u...
