Pretrained Neural Network Models for Guo 2018 study - TensorFlow format

Tiancheng Guo
The presence of raindrop induced image distortion has a significant negative impact on the performance of a wide range of all-weather visual sensing applications including within the increasingly important contexts of visual surveillance and vehicle autonomy. A key part of this problem is robust raindrop detection such that the potential for performance degradation in effected image regions can be identified. Here we address the problem of raindrop detection in colour video imagery by considering three...

Data Supporting "Interfacial contribution to thickness dependent in-plane anisotropic magnetoresistance", AIP Advances 5, 127108 (2015)

Mustafa Tokac, Mu Wang, Samridh Jaiswal, Andrew Rushforth, Bryan Gallagher, Del Atkinson & Aidan Hindmarch
(Abstract from article) We have studied in-plane anisotropic magnetoresistance(AMR) in cobaltfilms with overlayers having designed electrically interface transparency. With an electrically opaque cobalt/overlayer interface, the AMR ratio is shown to vary in inverse proportion to the cobaltfilm thickness; an indication that in-plane AMR is a consequence of anisotropic scattering with both volume and interfacial contributions. The interface scattering anisotropy opposes the volume scattering contribution, causing the AMR ratio to diminish as the cobaltfilm thickness is...

Time-Dependent Ginzburg-Landau Simulations of the Critical Current in Superconducting Films and Junctions in Magnetic Fields

Alexander I. Blair & Damian Hampshire
Understanding the magnetic field dependence of the critical current density (Jc) of superconductors is of considerable interest for optimizing their use in high field applications. Using time-dependent Ginzburg—Landau theory, we have completed simulations of the average electric field generated in thin film systems subject to transport currents in applied magnetic fields, and compared them to thin film systems containing narrow junctions of reduced critical temperature (Tc). For thin films in contact with insulating surfaces, Jc...

Deviations from Born-Oppenheimer mass scaling in spectroscopy and ultracold molecular physics: research data

Jeremy M. Hutson & Jesse J. Lutz
We investigate Born-Oppenheimer breakdown (BOB) effects (beyond the usual mass scaling) for the electronic ground states of a series of homonuclear and heteronuclear alkali-metal diatoms, together with the Sr$_2$ and Yb$_2$ diatomics. Several widely available electronic structure software packages are used to calculate the leading contributions to the total isotope shift for commonly occurring isotopologs of each species. Computed quantities include diagonal Born-Oppenheimer corrections (mass shifts) and isotopic field shifts. Mass shifts dominate for light...

iGIMP: An implicit generalised interpolation material point method for large deformations (figure data)

T.J. Charlton, W.M. Coombs & C.E. Augarde
The Material Point Method (MPM) uses a combined Eulerian-Lagrangian approach to solve problems involving large deformations. A problem domain is discretised as material points which are advected on a background grid. Problems are encountered with the original MPM when material points cross between grid cells, and this has been tackled by the development of the Generalised Interpolation MPM, where material points' domains of influence extend beyond the currently occupied grid cell. In this paper, the...

Dynamic Vorticity Banding in Discontinuously Shear Thickening Suspensions [software]

Rahul Chacko, Romain Mari, Michael Cates & Suzanne Fielding
It has recently been argued that steady-state vorticity bands cannot arise in shear thickening suspensions because the normal stress imbalance across the interface between the bands will set up particle migrations. In this Letter, we develop a simple continuum model that couples shear thickening to particle migration. We show by linear stability analysis that homogeneous flow is unstable towards vorticity banding, as expected, in the regime of negative constitutive slope. In full nonlinear computations, we...

Non-intrusive torque measurement for rotating shafts using optical sensing of zebra-tapes [dataset]

Donatella Zappalá, Matteo Bezziccheri, Christopher James Crabtree & Nicola Paone
Non-intrusive, reliable and precise torque measurement is critical to dynamic performance monitoring, control and condition monitoring of rotating mechanical systems. This paper presents a novel, contactless torque measurement system consisting of two shaft-mounted zebra tapes and two optical sensors mounted on stationary rigid supports. Unlike conventional torque measurement methods, the proposed system does not require costly embedded sensors or shaft-mounted electronics. Moreover, its non-intrusive nature, adaptable design, simple installation and low cost make it suitable...

Overcoming volumetric locking in material point methods (figure data)

William Coombs, Tim Charlton, Michael Cortis & Charles Augarde
Material point methods suffer from volumetric locking when modelling near incompressible materials due to the combination of a low-order computational mesh and large numbers of material points per element. Large numbers of material points per element are required to reduce integration errors due to non-optimum placement of integration points. This restricts the ability of current material point methods in modelling realistic material behaviour. This paper presents for the first time a method to overcome finite...

Mechanical properties of biopolymer-stabilised soil-based construction materials [dataset]

Sravan Muguda Viswanath, Samuel Booth, Paul Hughes, Charles Augarde, Celine Perlot, Agostino Walter Bruno & Domenico Gallipoli

Data from: Towards a mechanistic understanding of carbon stabilization in manganese oxides.

Karen Johnson, Graham Purvis, Elisa Lopez-Capel & Jesus Ojeda
Minerals are known to stabilise organic carbon in sediments, affecting biogeochemical cycles and global climate, but the mechanism is not understood. Here, the authors suggest that manganese oxides can trap organic carbon and may act as a 'mineral pump', transforming carbon between labile and refractory forms.

Influence of soil grading on the hygro-mechanical properties of hyper-compacted earth for masonry construction [dataset]

Alessia Cuccurullo
This paper presents a study, at material scale, of the dependency between particle size distribution and the mechanical, hygroscopic and durability properties of compacted raw (unfired) earth for manufacturing bricks. Stiffness and strength are measured by unconfined compression tests while vapour adsorption/desorption is investigated by moisture buffering tests. In addition, the durability to water erosion is evaluated by immersion tests. All experiments were performed on cylindrical earth samples compacted at a very high pressure (100...
