Molecular model of biaxial ordering in nematic liquid crystals composed of flat molecules with four mesogenic groups
(2010)Relative stability of uniaxial and biaxial nematic phases is analyzed in a model nematic liquid crystal composed of flat molecules of C-2h symmetry with four mesogenic groups rigidly linked to the same center. The generalized ... -
Molecular Organisation in “de Vries” Smectic Liquid Crystals: Characterisation and Theory
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2018)The study of anomalous temperature dependence of smectic layer thickness began fifty years ago. Liquid crystals exhibiting such properties were later classified as de Vries smectic liquid crystals. In this thesis I have ... -
Molecular orientation and the infrared dichroism of a chiral smectic liquid crystal in a homogeneouslyusly aligned cell at different temperatures and bias fields
(2003)The molecular orientation and the dichroic behavior of the vibrational bands of a homogeneously aligned helical cell containing chiral smectic liquid crystal ~R!-~-!-1-methylheptyl 4- (48-dodecyloxybiphenyl-4-ylcarbony ... -
Molecular orientational properties of a high-tilt chiral smectic liquid crystal determined from its infrared dichroism
(2007)The orientational characterisitics and the temperature dependencies of the molecular apparent tilt angle of a partly fluorinated chiral smectic liquid crystal (/S/)-4-(1-methylheptyloxycarbonyl)phenyl 4-[6-(3,4,4,4-tetra ... -
Molecular tilt angle and order parameter of low molar mass ferroelectric liquid crystal using IR spectroscopy
(1996)Fourier transform infrared spectroscopy of a ferroelectric liquid-crystalline material: 4-(3)-(S)- methyl-2-(S)-chloropentanoyloxy-4'-octyloxy-biphenyl has been investigated in the wavenumber range 450 - 4000 cm-1 for ... -
Monetary Consequence Prediction for Hazardous Liquid Pipelines in US
(2023)There are more than 230,000 miles of hazardous liquid pipelines in the US, and more than 4,000 significant incidents have been reported since 2010 with 3.1-billion-dollar damage. The cost consequence estimation of pipeline ... -
Monitoring and prediction of traffic-related urban air pollution
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2001)This research project involved the investigation of urban air quality with a view to (a) adding to the limited information on the state of the atmospheric environment in Dublin, Ireland and (b) formulating a methodology ... -
Monitoring environmental supporting conditions of a raised bog using remote sensing techniques
(2018)Conventional methods of monitoring wetlands and detecting changes over time can be time-consuming and costly. Inaccessibility and remoteness of many wetlands is also a limiting factor. Hence, there is a growing recognition ... -
Monitoring of Flexible Support Effects Using the Responses of Multi-span Bridges via Wavelet Transform
(2012)In this paper the temporal and spectral effects of the flexible support on the response of multi-span bridges subjected to spatially-varying differential support motions are investigated by using wavelet transform. The ... -
Monitoring of traffic related hydrocarbon concentrations
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2005)The research completed represents an experimental investigation of atmospheric hydrocarbon concentrations in the Dublin area, of which very little reported data were previously available. There was a notable lack of ... -
MONITORING OF VOLUME STATUS USING A NOVEL SENSOR FOR THE ASSESSMENT OF INFERIOR VENA CAVA AREA AND COLLAPSIBILITY IN A PATIENT WITH HFREF RECEIVING ADVANCED HEART FAILURE THERAPIES
(2023)Background: A novel sensor designed to measure infe- rior vena cava (IVC) area over time was used in this study (FIRE1). The system consists of the implantable sensor and an external belt, which is worn around the ... -
Monitoring the Static Vehicle Load on a Heavy Goods Vehicle
(2015)Static vehicle load can be calculated accurately from measurements of axle strain. This paper describes, in outline form, a series of laboratory and field tests on an instrumented heavy goods vehicle. The vehicle was ... -
The mortars of Coliemore harbour: comparison with other 19th century mortars of harbours and fortifications in Dublin Bay
(2023)This paper investigates the mortars used to build Coliemore harbour in 1869: their materials, sources, technology and current condition. It compares their composition with other Dublin harbours and fortifications in ... -

Motion model selection in tracking humans
(IET, 2006)The performance of many human tracking algorithms rely on accurate motion models. Due to the nature of human motion it is often difficult to determine the suitability of a chosen model. It is typically the case that over ... -
Multi fidelity Information Fusion for Efficient Estimation of Small Failure Probabilities Considering Multiple Limit States
(2023)Stochastic simulation methods, such as Monte Carlo simulation (MCS), are typically used to estimate failure probabilities in reliability analysis, but they can be computationally intensive, often requiring many evaluations ...
