The cruciform model of striate generation of the early VEP, re-illustrated, not revoked: A reply to Ales et al. (2013)
(2013)Here we summarize the points raised in our dialog with Ales and colleagues on the cortical generators of the early visual evoked potential (VEP), and offer observations on the results of additional simulations that were ... -
Feasibility Study and Cost-Benefit Analysis of Tidal Energy: A Case Study for Ireland
(2012)Ireland set out to produce 33% of its electricity demand from renewable sources by 2020 and reduce emissions to the level of 1990 in accordance with the Kyoto agreement. These targets require investments in a diverse ... -
General Reduced-Order Model to Design and Operate Synthetic Jet Actuators
(2012)Synthetic jets are used in various applicat ions from flow contro l to thermal management of electronics. Controlling the jet operating point using a simple voltage to velocity calibration becomes unreliable in case ... -
Experimental Validation of a Computational Fluid Dynamics Methodology for Transitional Flow Heat Transfer Characteristics of a Steady Impinging Jet
(2014)This paper presents a computational fluid dynamics (CFD) methodology to accurately predict the heat transfer characteristics of an unconfined steady impinging air jet in the transitional flow regime, impinging on a planar ... -
Flow regime characterisation of an impinging axisymmetric synthetic jet
(2013)Impinging synthetic jets have excellent potential for energy-efficient local cooling in confined geometries. For a given geometry, synthetic jet flows are mainly characterised by the Reynolds number and the ratio of stroke ... -
Scaling of Convective Heat Transfer Enhancement Due to Flow Pulsation in an Axisymmetric Impinging Jet
(2013)Impinging jets are widely used to achieve a high local convective heat flux, with applications in high power density electronics and various other industrial fields. The heat transfer to steady impinging jets has been ... -
A validated numerical-experimental design methodology for a movable supersonic ejector compressor for waste-heat recovery
(2013)The aim of this paper is to develop the technical knowledge, especially the optimum geometries, for the design and manufacturing of a supersonic gas-gas ejecto r for a waste heat driven vehicle cooling system. Although ... -
A comparison of self-assembly and hydrogel encapsulation as a means to engineer functional cartilaginous grafts using culture expanded chondrocytes.
(2014)Despite an increased interest in the use of hydrogel encapsulation and cellular self-assembly (often termed "self-aggregating" or "scaffold-free" approaches) for tissue-engineering applications, to the best of our knowledge, ... -
Exploring the roles of integrin binding and cytoskeletal reorganization during mesenchymal stem cell mechanotransduction in soft and stiff hydrogels subjected to dynamic compression.
(2014)The objective of this study was to explore how the response of mesenchymal stem cells (MSCs) to dynamic compression (DC) depends on their pericellular environment and the development of their cytoskeleton. MSCs were first ... -
Infrapatellar Fat Pad-Derived Stem Cells Maintain Their Chondrogenic Capacity in Disease and Can be Used to Engineer Cartilaginous Grafts of Clinically Relevant Dimensions.
(2014)A therapy for regenerating large cartilaginous lesions within the articular surface of osteoarthritic joints remains elusive. While tissue engineering strategies such as matrix-assisted autologous chondrocyte implantation ... -
Substrate stiffness and oxygen availability as regulators of mesenchymal stem cell differentiation within a mechanically loaded bone chamber.
(2014)M echanical stimuli such as tissue deformation and fluid flow are often implicated as regulators of mesenchymal stem cell (MSC) differentiation during regenerative events in vivo . However , in vitro studies ... -
Controlled release of transforming growth factor-ß3 from cartilage-extra-cellular-matrix-derived scaffolds to promote chondrogenesis of human-joint-tissue-derived stem cells.
(2014)Abstract: The objective of this study was to develop a scaffold derived from cartilaginous extracellular matrix (ECM) that could be used as a growth factor delivery system to promote chondrogenesis of stem cells. ... -
Blotch and scratch removal in archived film using a semi-transparent corruption model and a ground-truth generation technique
(Springer, 2013)This paper has two main contributions. The first is a Bayesian framework for removing two common types of degradations on video known as blotches and line scratches. Most removal techniques assume complete obliteration of ... -
On the Modeling of Spar-type Floating Offshore Wind Turbines
(2013-07)In this paper an overview about floating offshore wind turbines (FOWT) including operating conditions, property and applicability of the barge, tension-leg, and spar floating platforms is described. The spar-floating ... -
Polarization anisotropy of photoluminescence from triphenylamine-based molecular single crystal
(2013)We present an experimental study of the polarization of the photoluminescence (PL) emission from a (Z)-3-(4-(diphenyl- amino)phenyl)-2-(pyridin-2-yl)-acrylonitrile (DPPyACN) single organic crystal. Our measurements show ... -
Influence of the buffer layer properties on the intensity of Raman scattering of graphene
(2013)Using a model of oscillating dipoles, we simulate the intensity of the G-band in the Raman signal from structures consisting of graphene, separated by an arbitrary buffer layer from a substrate. It is found that a structure ... -
Engineering cartilage or endochondral bone: A comparison of different naturally derived hydrogels.
(2015)Cartilaginous tissues engineered using mesenchymal stem cells (MSCs) have been shown to generate bone in vivo by executing an endochondral programme. This may hinder the use of MSCs for articular cartilage regeneration, ... -
Spin-torque effects in thermally assisted magnetisation reversal: Method of statistical moments
(2013)Thermal fluctuations of nanomagnets driven by spin-polarized currents are treated via the Landau-Lifshitz-Gilbert equation generalized to include both the random thermal noise field and the Slonczewski spin-transfer torque ... -
