BACKGROUND Magnetic stimulation has gained relatively wide application in studying nervous system structures. This technology has the advantage of reduced excitation of sensory nerve endings, and hence results in quasi-painless action. It has become clinically accepted modality for brain stimulation. However, theoretical and practical solutions for assessment of induced current distribution nee...

are not. (In the second example, the two sets can be mapped to each other by a partial automorphism, but not by one that extends to a automorphism of the real numbers.) Here is the definition of FM sets. The definition is parametrized by a set of atoms. The atoms are given as a relational structure, which induces a notion of automorphism. (One can also consider atoms with function symbols, but ...

DMUs under DEA evaluation are assumed to be homogeneous. That means the units should undertake similar activities, use common technologies, and operate in similar environments. If one of these assumptions is violated, the efficiency estimates of these DMUs will be biased. This paper firstly analyzes the impacts of DMUs’ non-homogeneity caused by technology difference on the efficiency estimates...

We present a method for Shape-from-Texture in one of its most general forms. Previous Shape-from-Texture papers assume that the texture is constrained by one or more of the following properties: homogeneity, isotropy, stationarity, or viewed orthographically. We make none of these assumptions. We do not presume that the frontal texture is known a priori, or from a known set, or even present in ...

We study the (parabolic) hydrodynamic limit of linear kinetic equations. We deal with collision terms which do not satisfy detailed balance pinciple and where the coeecients depend on the space variable. The possible dependence of the equilibrium upon position induces an additional drift term in the limit equation.

This paper describes an automatic and efficient approach to construct unstructured tetrahedral and hexahedral meshes for a composite domain made up of heterogeneous materials. The boundaries of these material regions form non-manifold surfaces. In earlier papers, we developed an octree-based isocontouring method to construct unstructured 3D meshes for a single-material (homogeneous) domain with...

Nano Bioactive glass material of the type CaO–P2O5–SiO2 was obtained by the sol-gel processing method at considerably lower temperatures than required for conventional melting methods. As a new modification, volume of solution was changed in order to investigate its effects on the properties of bioglass samples. The obtained material was characterized by X-ray powder diffraction (XRD), surface ...

We have developed optical flow based techniques for finding the surface strain of an untreated sample of material from a sequence of images taken during the application of force from a test rig. Not all optical flow algorithms have suitable functional characteristics for this task, as image sequences are characterised by both shortand long-range displacements, non-rigid deformations, as well as...

In this Paper, we investigate numerically and analytically the thermal conductivity of nanoscale graphene disks (NGDs), and discussed the possibility to realize functionally graded material (FGM) with only one material, NGDs. Different from previous studies on divergence/non-diffusive of thermal conductivity in nano-structures with different size, we found a novel non-homogeneous (graded) therm...
