Fabrication, mechanical and in vivo performance of polycaprolactone/tricalcium phosphate composite scaffolds
(2012)This paper explores the use of selective laser sintering (SLS) for the generation of bone tissue engineering scaffolds from polycaprolactone (PCL) and PCL/tricalcium phosphate (TCP). Different scaffold designs are generated, ... -
Facial enhancement and beautification for HD video cameras
(IEEE, 2011)Influenced by the widespread adoption of HDTV consumer imaging devices have begun to feature full HD (high density) video capture. With this high-resolution capability, small imperfections in human faces are captured with ... -
Facial expression modeling using component AAM models - Gaming applications
(IEEE, 2009-10-23)In this paper we provide preliminary results on a new modeling approach for improved determination of facial expressions from a low-resolution video stream. An initial proof-of-concept using an extension of an Active ... -

Factors affecting Embodied Carbon/Embodied Energy associated with ground improvements techniques for construction on peat
(NUI Galway, 2012)In addition to the traditional drivers of cost and timely programme delivery, embodied energy (EE) and embodied carbon (EC) have emerged as major considerations in all aspects (including geotechnical) of large construction ... -
Factors affecting nitrate distribution in shallow groundwater under a beef farm in South Eastern Ireland
(Elsevier, 2009-07)Groundwater contamination was characterised using a methodology which combines shallow groundwater geochemistry data from 17 piezometers over a 2 yr period in a statistical framework and hydro-geological techniques. Nitrate-N ... -
Fake data - the future of advanced computer vision systems
(NUI Galway, 2018-10-22)Recent research shows that Data Augmentation techniques and Synthetic Data can improve the accuracy and reduce the susceptibility of Deep Neural Networks to Adversarial Attacks. In this presentation we consider some of the ... -
Fast A/V channel switching on a wireless home network
(IEEE, 2005-11-21)A method of enabling fast switching between multimedia streams on an 802.11g network is described. This technique is particularly useful for A/V home network applications where it is desirable to simulate the fast channel ... -
Fatigue damage characterisation of MarBN steel for high temperature flexible operating conditions
(SAGE Publications, 2016-09-10)This article is concerned with the high temperature low cycle fatigue behaviour of a new nano-strengthened martensiticferritic steel, MarBN. A range of strain-controlled, low cycle fatigue tests are presented on MarBN at ... -
Fatigue life of pitch- and stall-regulated composite tidal turbine blades
(Elsevier, 2018-02-28)Tidal turbine blades are subject to harsh loading and environmental conditions, including large thrust and torsional loadings, relative to wind turbine blades, due to the high density of seawater, among other factors. The ... -
A feasibility study on microwave imaging of bone for osteoporosis monitoring
(Springer, 2021-03-30)The dielectric properties of bones are found to be influenced by the demineralisation of bones. Therefore, microwave imaging (MWI) can be used to monitor in vivo dielectric properties of human bones and hence aid in the ... -
Field assessment of coconut-based activated carbon systems for the treatment of herbicide contamination
(Elsevier, 2023-12-03)Once released into the environment, herbicides can move through soil or surface water to streams and groundwater. Filters containing adsorbent media placed in fields may be an effective solution to herbicide loss in the ... -
Finite element modelling for mitigation of residual stress and distortion in macro-scale powder bed fusion components
(SAGE Publications, 2022-12-23)Powder bed fusion (PBF) has attracted significant attention in many applications due to its capability of fabricating complex and customized metal parts. However, the potential for high inherent residual stresses that ... -
Finite element modelling of brittle fracture of thick coatings under normal and tangential loading
(Elsevier ScienceDirect, 2012-09-12)This paper addresses coating fracture in hard brittle coatings subjected to combined normal and tangential loads through a finite element based methodology. The coating is modelled as an elastic layer perfectly bonded to ... -
Finite element modelling of damage in superplastic forming of a titanium alloy
(Springer Verlag, 2009-12-15)This paper describes the application of a continuum damage mechanics methodology to the prediction of failure during superplastic forming of Ti-6Al-4V. A power law constitutive relationship is employed within a geometrically ... -
Finite element modelling of the thermo-mechanical behaviour of a 9Cr martensitic steel
(Springer, Berlin, Heidelberg, 2013-01-01)A multi-axial, unified sinh viscoplastic material model has been developed to model the behaviour of advanced materials subjected to high temperature cyclic loading. The material model accounts for rate-dependent effects ... -
Finite element prediction of creep-plastic ratchetting and low cycle creep-fatigue for a large SPF tool
(Springer Verlag, 2010-03-03)Industrial experience shows that large superplastic forming (SPF) tools suffer from distortion due to thermal cycling, which apparently causes high temperature creep and plasticity. In addition to distortion, thermomechanical ... -
Finite element simulation and experimental validation of fretting wear
