Adaptive Linear Prediction For Optimal Control Of Wind Turbines, Mahinsasa Narayana, Keith Sunderland, Ghanim Putrus, Michael Conlon

Articles

In order to obtain maximum power output of a Wind Energy Conversion System (WECS), the rotor speed needs to be optimised for a particular wind speed. However, due to inherent inertia, the rotor of a WECS cannot react instantaneously according to wind speed variations. As a consequence, the performance of the system and consequently the wind energy conversion capability of the rotor are negatively affected. This study considers the use of a time series Adaptive Linear Prediction (ALP) technique as a means to improve the performance and conversion efficiency of wind turbines. The ALP technique is introduced as a real …

3d Printing Aids Acetabular Reconstruction In Complex Revision Hip Arthroplasty, Andrew J. Hughes, Cathal Debuitleir, Philip Soden, Brian O'Donnchada, Anthony Tansey, Ali Abdulkarim, Colm Mcmahon, Conor J. Hurson

Articles

Revision hip arthroplasty requires comprehensive appreciation of abnormal bony anatomy. Advances in radiology and manufacturing technology have made three-dimensional (3D) representation of osseous anatomy obtainable, which provide visual and tactile feedback. Such life-size 3D models were manufactured from computed tomography scans of three hip joints in two patients. The first patient had undergone multiple previous hip arthroplasties for bilateral hip infections, resulting in right-sided pelvic discontinuity and a severe left-sided posterosuperior acetabular deficiency. The second patient had a first-stage revision for infection and recurrent dislocations. Specific metal reduction protocols were used to reduce artefact. The images were imported into Materialise …

Electromechanical Instability In Silicone-And Acrylate-Based Dielectric Elastomers, Liang Jiang, Yanfen Shou, Shaojuan Chen, Jianwei Ma, Tony Betts, Stephen Jerrams

Articles

Electromechanical instability (EMI) is regarded as a significant factor in preventing dielectric elastomers (DEs) fromachieving large voltage-induced deformations. In this study, the strain-stiffening effect was used to control the occurrence of EMI in DEs. The results show that the stretching ratio required to provide a feasible strain-stiffening effect in silicone rubber (SR) was smaller than that needed for a commercial DE material, VHB 4910. The experimental data were compared with currently used models for the simulation of EMI in DEs. We found that EMI could be eliminated in the deformation of these elastomers when pre-stretching was used. Through the application …

Enhancement Of Dielectric Properties With The Addition Of Bromine And Dopamine Modified Barium Titanate Particles To Silicone Rubber, Liang Jiang, David Kennedy, Stephen Jerrams, Tony Betts

Articles

Dual-coated barium titanate (BT) particles were prepared using dopamine (DP) in conjunction with bromine (Br) in order to enhance the dielectric constant of silicone rubber (SR) composites containing evenly distributed BT particles. The results showed that both DP and Br were deposited on the BT particles. The dielectric constant of the SR/BT composite was significantly increased from 3.6 to 4.7 at 1 kHz with the addition of BT modified with dopamine (DP–BT). Moreover, the dielectric constant further rose to 4.9 at 1 kHz when the DP–BT particle was grafted with bromine (Br–DP–BT).

Optimising The Performance Of Cement-Based Batteries, Aimee Byrne, Shane Barry, Niall Holmes Dr., Brian Norton

Articles

The development of a battery using different cement-based electrolytes to provide a low but potentially sustainable source of electricity is described. The current, voltage, and lifespan of batteries produced using different electrolyte additives, copper plate cathodes, and (usually) aluminium plate anodes were compared to identify the optimum design, components, and proportions to increase power output and longevity. Parameters examined include water/cement ratio, anode to cathode surface area ratio, electrode material, electrode spacing, and the effect of sand, aggregate, salts, carbon black, silica fume, and sodium silicate on the electrolyte. The results indicate that the greatest and longest lasting power can …

Thermal Inactivation Analysis Of Water-Related Pathogens In Domestic Hot Water Systems, Liam Mccarton, Sean O'Hogain

Articles

This study aims to investigate whether hot water systems supplied with harvested rainwater present an increased risk to health over hot water systems supplied with potable mains water. It reviews previous studies investigating the health effects of utilising rainwater within domestic systems. The main risk to public health of mains-supplied hot water systems is the operation, maintenance, age, location and temperature of the system. Rainwater-harvesting systems contain an inherent water treatment train consisting of flocculation, settlement, sorption and bioreaction, and stored rainwater quality improves as metal and chemical contaminants settle to form sludge. Laboratory experiments were conducted using a variety …

Stochastic Modelling For Levy Distributed Systems, Jonathan Blackledge, T Raja Rani

Articles

The purpose of this paper is to examine a range of results that can be derived from Einstein’s evolution equation focusing on (but not in an exclusive sense) the effect of introducing a L´evy distribution. In this context, we examine the derivation (as derived from the Einstein’s evolution equation) of the classical and fractional diffusion equations, the classical and generalised Kolmogorov-Feller equations, the evolution of self-affine stochastic fields through the fractional diffusion equation and the fractional Schr¨odinger equation, the fractional Poisson equation (for the time independent case), and, a derivation of the Lyapunov exponent. In this way, we provide a …

Enhanced Network Voltage Management (Nvm) Techniques Under The Proliferation Of Rooftop Solar Pv Installation In Low Voltage Distribution Network (Lvdn), Shivananda Pukhrem, Malabika Basu, Michael Conlon, Keith Sunderland

Articles

Proliferation of rooftop solar PV distributed generator (PVDG) installation in low voltage distribution network (LVDN) imposes voltage fluctuation challenges that are a threat to distribution system operators. Reactive power control (RPC) methods are insufficient in isolation to combat the overvoltage fluctuations manifested in LVDN with significant grid-tied PVDG installations. Whereas active power curtailment (APC) control can alleviate the voltage fluctuation in such situations and it is achieved at the cost of reduced active power injection. This paper explores how deficiencies in both RPC and APC as separate approaches can be mitigated by suitably combining RPC and APC algorithms. Strategies combining …

Dye-Sensitised Solar Cell Antenna, Oisin O'Conchubhair, Patrick Mcevoy, Max Ammann

Articles

Dye-sensitised solar cells are proposed as a solarantenna in the form of a proof-of-concept dipole operating at 1.1 GHz. Comprised of glass plates in basic rectangular shapes, various material properties are considered for impact on antenna performance at three phases of assembly. Simulated and empirical analyses indicate how such low-cost solar cells can also realise viable concurrent antenna designs.

Magnetic Field Sensor Based On A Combination Of A Microfiber Coupler Covered With Magnetic Fluid And A Sagnac Loop, Fangfang Wei, Arun Mallik, Dejun Liu, Qiang Wu, Gang-Ding Peng, Gerald Farrell, Yuliya Semenova

Articles

This paper proposes a novel magnetic field sensor based on a microfiber coupler (MFC) combined with a magnetic fluid (MF) in a Sagnac loop formed from a polarization maintaining fiber (PMF). Thanks to the small (~2.6 μm) waist diameter of the MFC, the resulting interference is strongly influenced by the presence of the MF and this leads to the desirable high sensitivity of the structure to the applied magnetic field. The maximum magnetic field sensitivities of −100 pm/mT and −488 pm/mT have been experimentally demonstrated with the PMF lengths of 75 cm and 20 cm respectively in the range of …

Humidity And Temperature Induced Changes In The Diffraction Efficiency And The Bragg Angle Of Slanted Photopolymer-Based Holographic Gratings, Tatsiana Mikulchyk, James Walshe, Dervil Cody, Suzanne Martin, Izabela Naydenova

Articles

This work explores the humidity and temperature response of volume phase slanted gratings recorded in photopolymers with varied chemical composition. Acrylamide and diacetone acrylamide were used as monomers and triethanolamine and N-phenylglycine were used as photoinitiators. The study demonstrates that the response of photopolymer-based holographic gratings to relative humidity (RH) and temperature (T) can be tuned by alteration of the photopolymer composition.Humidity and temperature response of the holograms has been characterized by recording Bragg selectivity curves of transmission gratings and by monitoring the position of the maximum intensity in the spectral response of reflection gratings. Investigation of the humidity response …

Beyond Logic And Norms: A Figurational Critique Of Institutional Theory In Organisation Studies, Paddy Dolan, John Connolly

Articles

This paper provides a figurational critique of one of the most dominant theoretical frames within organisation studies - institutional theory. Despite its status as the leading theoretical lens for explaining organisational change, institutional theorists continue to struggle with the so called agencystructure issue and remain divided in how to overcome it. Our primary criticisms concern the propensity to invoke or generate dualisms, the reliance on the sociological frames which sustain this, and the failure to engage in any comprehensive way with Elias’s writings on this subject.

Connected Health: An Open Innovation Perspective., Anushree Priyadarshini, Maria Quinlan, Gerardine Doyle

Articles

The concept of connected health has gained traction in recent years as a new technology enabled and networked model of health care delivery. It is often used as an umbrella term for eHealth, digital health, health informatics, telemedicine, mHealth and involves the establishment and management of a network of stakeholders with the aim of improving health care quality and out- comes. Yet a lack of open interactions and knowledge networks and the missing integration of the larger constituency of interdisciplinary experts are limiting the execution of the model and restricting its potential to devise services and interventions around patient’s needs …

G-Strands On Symmetric Spaces, Alexis Arnaudin, Darryl Holm, Rossen Ivanov

Articles

We study the G-strand equations that are extensions of the classical chiral model of particle physics in the particular setting of broken symmetries described by symmetric spaces. These equations are simple field theory models whose configuration space is a Lie group, or in this case a symmetric space. In this class of systems, we derive several models that are completely integrable on finite dimensional Lie group G, and we treat in more detail examples with symmetric space SU(2)/S1 and SO(4)/SO(3). The latter model simplifies to an apparently new integrable nine-dimensional system. We …

Europe's Moral Margin: Parental Aspirations And The European Court Of Human Rights, Clare Ryan

Articles

The European Court of Human Rights (ECtHR) balances along two axes: individual right vs. government interest and national vs. supranational judgment. The Court calibrates the level of deference it affords States through the margin of appreciation, a doctrine designed to vary how strictly the supranational court will scrutinize national decisions. This Article challenges the way in which the Court deploys margin of appreciation in order to defer to "sensitive moral and ethical" decisions taken by domestic institutions. I call this deference the "moral margin." Although the European Convention on Human Rights explicitly authorizes the Court to take "protection of morals" …
