A Simple Model Relating Gauge Factor to Filler Loading in Nanocomposite Strain Sensors
(2021)
Conductive nanocomposites are often piezoresistive, displaying significant changes in resistance upon deformation, making them ideal for use as strain and pressure sensors. Such composites typically consist of ductile ...
Genetic algorithm optimization of high order surface etched grating tunable laser array
(2020)
A genetic algorithm is developed with a view to optimizing surface-etched grating tunable lasers over a large optimization space comprised of several variables. Using this approach, a new iteration of slotted lasers arrays ...
Ion outflow and soft X-ray radiation from a micro capillary discharge source and laser produced plasma
(Trinity College (Dublin, Ireland). School of Physics, 2002)
This thesis concerns itself with the study of pulsed plasma sources. The plasma is produced either in an electrical discharge or by a laser pulse. The plasma is generated
on a nanosecond time scale, after which it evolves ...
Vector vibrating-sample magnetometer with permanent magnet flux source
(2006)
A compact magnetometer, which uses two nested 1?T Halbach cylinders to generate a variable magnetic field of up to 2?T in any direction in the xy plane, has two sets of quadrupole pickup coils to detect the components mx ...
Athermalisation and Characterisation of High-OrderSurface Grating Lasers for Optical Communications
(Trinity College Dublin. School of Physics. Discipline of Physics, 2023)
The semiconductor laser allows for the vast quantities of data that are transmitted over optical fibre each day. A simple device has transformed our
lives. This transformation will continue in the coming decade where ...
Variation of average coordination number with liquid fraction for two-dimensional foams with finite contact angle
(2021)
We present Surface Evolver computer simulations for two-dimensional (2d) foams in which the contact angle at which liquid films and Plateau borders meet is non-zero. We determine the average coordination number Z of bubbles ...
Assessment of the accuracy of an ultrasound elastography liver scanning system using a PVA-cryogel phantom with optimal acoustic and mechanical properties
(2010)
The accuracy of a transient elastography liver-scanning ultrasound system was assessed using a
novel application of PVA-cryogel as a tissue-mimicking material with acoustic and shear
elasticity properties optimized to ...
Characterisation of a fast microcapillary discharge plasma using a compact multi-deflector Thomson parabola ion analyser
(IEEE, 2001)
A compact Thomson parabola ion analyser has been developed and tested on a fast
microcapillary plasma discharge. The discharge cell comprises a circular parallel-plate
capacitor (1 - 2 nF) with a 50 micron sized hole in ...
Ink-Jet Printing: Perfect Tool for Cantilever Array Sensor Preparation for Microbial Growth Detection
(2012)
The use of microcantilever arrays for microbial growth detection provides a rapid and reliable technique for monitoring growth in industrial and clinical applications. Improving the reproducibility and sensitivity of this ...
Liquid phase exfoliation of two dimensional crystals
(Trinity College (Dublin, Ireland). School of Physics, 2013)
