The knowledge of in vivo human brain deformation within the skull is essential in understanding brain injury mechanisms. Such measurements have become possible only in recent years thanks to the advancement of magnetic resonance imaging (MRI) technique. In this paper, we first study in vivo human brain deformation under mild impact induced by a 2cm head drop using tagged MRI and the harmonic ph...

We study all possible deformations of the Maxwell algebra. In D = d + 1 6= 3 dimensions there is only one-parameter deformation. The deformed algebra is isomorphic to so(d+ 1, 1)⊕ so(d, 1) or to so(d, 2)⊕ so(d, 1) depending on the signs of the deformation parameter. We construct in the dS(AdS) space a model of massive particle interacting with Abelian vector field via non-local Lorentz force. I...

We modify the deformation method from [9] in order to construct further examples of Kobayashi hyperbolic surfaces in P of any even degree d ≥ 8. Given a hypersurface Xd = f ∗ d (0) in P n of degree d, we say that a (very) general small deformation of Xd is hyperbolic if for any (very) general degree d hypersurface X∞ = g ∗ d(0) and for all sufficiently small ε ∈ C \ {0} (depending on X∞) the hy...

Liquid crystal elastomers (LCE) are elastomeric networks with mesogen moieties that can reorient and order in response to thermomechanical loads. Experiments have shown the stress of nematic LCEs is rate-dependent exhibits large hysteresis upon load–unload. In this work, we developed a theory for deformation viscoelastic behavior monodomain separately incorporates hypothesized dissipation mecha...

determination of the deformation length is one of the first steps in roll forming design. roll forming industries are very interested in explicit simple relationsfor prediction the deformation length without using trail-and-error methods at workshop or time consuming finite element simulations. in this paper, elastic properties and work-hardening behaviour of the strip are considered in additio...

Fuzzy functional dependency (FFD) is a kind of semantic knowledge and can be discovered from a large volume of business data. Sectional FFD and Attribute FFD are discussed so as to reflect semantics of the business world and express useful information that is natural for people to comprehend. The experimental results on an insurance data set show that the proposed method can extract knowledge e...

One of the key issues in structural and geotechnical engineering is that most parts buildings are usually analysed separately then outputs used foundation designs. In this process, some effects neglected. study, soil–structure interaction (SSI) foundations concrete was evaluated using direct finite element method (DFEM). 3D models were developed to analyse with different stories constructed on ...

In the last two decades, scientists have developed a powerful technique to measure the millimeterscale of the Earth ̳s surface deformation by comparing complex synthetic aperture radar (SAR) data that were acquired a few days or a few years apart. This technique is known as interferometric synthetic aperture radar (InSAR). The paper is focused on simulation of volume deformation of coastal éros...

Any deformation of a Weyl or Clifford algebra A can be realized through a ‘deforming map’, i.e. a formal change of generators in A. This is true in particular if A is covariant under a Lie algebra g and its deformation is induced by some triangular deformation Uhg of the Hopf algebra Ug . We propose a systematic method to construct all the corresponding deforming maps, together with the corresp...
