Characteristic classes of complexified bundles
(Summer School in Algebraic Topology: Sheaf theoretic methods in the theory of characteristic classes, 2007)
We examine the topological characteristic cohomology classes of complexified vector bundles . In particular, all the classes coming from real vector bundles are computed. We use characteristic classes with the ax-ioms of ...
Generalized Moonshine and orbifold constructions.
(Research Institute for Mathematical Sciences (Kokyuroku), 2002)
A brief review is given of some of our recent work on Generalised Monstrous Moonshine using abelian orbifoldings of the Moonshine Module.
Experimental characterisation of neural tissue at collision speeds
(International Research Council on Biomechanics of Injury (IRCOBI), 2012)
Mechanical characterisation of brain tissue at high loading velocities is particularly important for modelling Traumatic Brain Injury (TBI). During severe impact conditions, brain tissue experiences a mixture of compression, ...
Strain rate effects on the failure characteristics of excised human skin
(The 9th International Conference on the Mechanics of Time Dependent Materials, 2014)
Skin is a complex, multi-layered material which exhibits non-linear, anisotropic and viscoelastic behaviour. Its structure is complex and can be broadly divided into three main layers: the epidermis, the dermis and ...
Finite-amplitude Love waves in a pre-stressed neo-Hookean material
In the context of the non-linear elasticity theory we consider a model for compressible solids called compressible neoHookean material . We show how (exact) finite-amplitude inhomogeneous plane wave solutions and ...
Waves and vibrations in a solid of second grade
(World Scientific, 2006)
We study the viscoelastic second grade solid, for which the constitutive equation consists in the sum of a purely elastic part and a viscoelastic part; this latter part is specified by two microstructural coefficients ...
A note about waves in dissipative and dispersive solids
(World Scientific, 2008)
We study shear waves propagating in a special viscoelastic model proposed first by Fosdick and Yu in 1996. We deduce an asymptotic approximation which reduces the full balance equations to a system of evolution equations ...
Mechanical properties of excised human skin
(Springer Verlag, 2010)
In this study we have investigated in influence of location, gender and orientation on the deformation characteristics of 55 samples of human excised skin. Uniaxial tensile tests were carried out at a strain rate of ...
Experimental assessment of MRI-induced temperature change and SAR distributions in phantoms
(NUI Galway, 2017-11-14)
During an MR procedure, most of the transmitted RF power is transformed into heat within the patients’ tissue resulting from resistive losses, referred to as the specific energy absorption rate(SAR) (2). The EU standardisation ...
Label free ultra-sensitive imaging with sub-diffraction spatial resolution
In this paper, we show a new way to break the resolution limit and dramatically improve sensitivity to structural changes. To realize it we developed a novel label free contrast mechanism, based on the spectral encoding ...
