Linear irregular wave generation in a numerical wave tank
(Elsevier, 2015-07-09)
In the design of any floating or fixed marine structure, it is vital to test models in order to understand the fluid/structure interaction involved. A relatively inexpensive method, compared to physical model testing, of ...
Proof-of-concept and evaluation of a dual function visible/NIR camera for iris authentication in smartphones
(Institute of Electrical and Electronics Engineers, 2015-05)
As a robust method of person authentication, iris biometrics is making its way in to consumer devices such as smartphones. Current iris image acquisition devices typically work under controlled environment and constrained ...
Evaluating the effect of increasing ceramic content on the mechanical properties, material microstructure and degradation of selective laser sintered PCL/b-TCP materials
(Elsevier, 2015-06-06)
Orthopaedic scaffold materials were fabricated from polycaprolactone (PCL) and composite PCL β-tricalcium phosphate (PCL/β-TCP) powders using selective laser sintering (SLS). Incorporating β-TCP particles is ...
Shaft resistance of driven cast-in-situ piles in sand
(NRC Research Press, 2015-06-25)
Driven cast-in-situ (DCIS) piles are classified as a large displacement pile, despite sharing certain aspects of their construction with replacement pile types. However, there are relatively few case histories of load tests ...
Pile group settlement estimation: suitability of nonlinear interaction factors
(American Society of Civil Engineers, 2015-06)
In this paper, predictions of pile settlement determined by appropriate superposition of two-pile interaction factors are compared with those computed from continuum analysis. A finite-element package is used in conjunction ...
Numerical modelling of pile foundation angular distortion
(Elsevier, 2015-05-16)
In this paper, the PLAXIS 3-D Foundation finite element (FE) software package, in conjunction with the nonlinear Hardening Soil (HS) constitutive model, is employed in an extensive parametric study of the angular distortion ...
Pyritiferous mudstone-siltstone: expansion rate measurement and prediction
(Geological Society, 2015)
The expansion rates of a pyritiferous Irish mudstone-siltstone fill material have been measured over a period of 19 months in an apparatus devised to replicate underfloor conditions. The testing, performed in a ...
Iris authentication in handheld devices - considerations for constraint-free acquisition
(IEEE, 2015-05)
As a near ideal biometric, iris authentication is widely used and mobile acquisition techniques are known. But iris acquisition on handheld imaging devices, such as smartphones, poses multiple, unique challenges. In this ...
Altered mechanical environment of bone cells in an animal model of short- and long-term osteoporosis
(Biophysical Society, 2015-04-07)
Alterations in bone tissue composition during osteoporosis likely disrupt the mechanical environment of bone cells and may thereby initiate a mechanobiological response. It has proved challenging to characterize the ...
Computational modelling of ovine critical-sized tibial defects with implanted scaffolds and prediction of the safety of fixator removal
(Elsevier, 2015-01-14)
Computational model geometries of tibial defects with two types of implanted tissue engineering scaffolds, β-tricalcium phosphate (β-TCP) and poly-ε-caprolactone (PCL)/β-TCP, are constructed from µ-CT scan images of the ...
