What we can't learn from nature
(2011)When attempting to design bio-inspired materials and structures, it is important to remember that Nature employs some strategies for optimising the use of load-bearing materials which we, as engineers, cannot replicate. A ... -
Whispering gallery mode emission from photonic microtubes
(IEEE, 2006)We have found cylindrical glass microtubes can be formed by vacuum assisted filtration using a micro-channel glass matrix followed by thermal treatment of the material. The microtubes are strongly luminescent and exhibit ... -
Whispering-gallery modes in photonic tubes
(Society of Photo-optical Instrumentation Engineers (SPIE), 2007)A new method has been developed to fabricate microtube resonators with strong whispering-gallery-mode emission and quality factors up to 3000. -
Whitespace Networks Relying on Dynamic Control Channels
(2013)The emergence of whitespace networks, and whitespace communications in general, provides an opportunity to, at least partially, meet the ever-growing demand for mobile data communication. Most of the whitespace network ... -
"Who said that?" Applying the Situation Awareness Global Assessment Technique to Social Telepresence
(2023)As with all remotely-controlled robots, successful teleoperation of social and telepresence robots relies greatly on operator situation awareness, however existing situation awareness measurements, most being originally ... -
Whole-Body Magnetic Resonance Imaging Enables Assessing Spatial Accuracy and Precision of Skeletal Joint Locations Inferred from Motion Capture Systems
(2015)Motion capture systems can be used to infer skeletal joints from three-dimensional surface information for various human poses. However, to-date it remains unclear how well the estimated joint coordinates coincide with ... -
Whole-body sodium-mri at 3 T using an asymmetric birdcage resonator and short echo time sequence: first images of a male volunteer
(2012)Sodium magnetic resonance imaging (²³Na MRI) is a non-invasive technique which allows spatial resolution of the tissue sodium concentration (TSC) in the human body. TSC measurements could potentially serve to monitor early ... -
Wide Range Performance Measurement and Low-Fidelity Modelling of Turbocharger Turbines for Optimising Powertrain Efficiency
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2024)Turbochargers have been widely used for many years and have made remarkable contributions in reducing the vehicle emissions by reducing the engine size while maintaining the same power output. They are also needed in designs ... -
Wide-band dielectric spectroscopy of small-molecule glass-forming liquids and insulating thin films
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2005)This thesis describes the application of broadband dielectric spectroscopy in the frequency range 1 mHz - 1.8 GHz to two main topics; (i) the glass transition and relaxation features of supercooled liquids and glasses, ... -
Wilting rationalism in technical decision making
(2023)Decision makers in diverse engineering disciplines, ranging from technical risk analysis and design to the development of risk-informed policies that impact on technology and society, benefit from the existence of a solid ... -
Wind Field Simulation and Fluid-Structure Interaction in Wind Farms
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2023)Wind energy as a renewable source has been a topic of immense interest over the past few decades. It is a well known fact that the wake structure influences the performance and operation of the wind turbines located further ... -

A wolf in sheep's clothing: Exposing the structural violence of private electric automobility
(2023)The world is running out of time to avoid cataclysmic climate impacts. Therefore, determining which decarbonisation strategies are more effective and inclusive in reducing anthropogenic dependency on fossil fuels is vital ... -
Workflow-induced uncertainty in probabilistic landslide hazard maps
(2023)Increasing complexity and capacity of computational physics-based landslide run-out modelling over the last few years yielded highly efficient model-based decision support tools, e.g. landslide susceptibility or run-out ... -
X-ray diffraction study of ferroelectric and antiferroelectric liquid crystal mixtures exhibiting de Vries SmA∗-SmC∗ transitions
(2010)In this Rapid Communication, results on smectic layer thickness, using synchrotron radiation x-ray diffraction, for different mixtures of ferroelectric and antiferroelectric liquid crystals are given. We find that with ...
