Acoustic particle velocity measurement by ultra-light membrane and its applications in acoustic holography
(Trinity College Dublin. School of Engineering. Mechanical & Manufacturing Engineering, 2007)Acoustic holography is a non-destructive method used to determine the spatial propagation of acoustical waves. Conventionally, the acoustic holography measures the acoustic pressure. Until recently, a very limited number ... -
Analysis of the Potential of DynaFlexPro as a Modeling Software by its Application in the Roll Stability of Heavy-Duty Elliptical Tankers using Trammel Pendulum to Simulate Fluid Sloshing
(Trinity College Dublin. School of Engineering. Mechanical & Manufacturing Engineering, INSA Lyon, 2007)One of the most common ways for commercial vehicles to loose their stability is by rollover. Partially filled heavy-duty tankers manoeuvring constant radius turns or lane change maneuvers have lower rollover threshold than ... -
Analysis of the rough contact in axisymmetric upsetting
(Trinity College Dublin. School of Engineering. Mechanical & Manufacturing Engineering, 2007)Characterization of surface roughness is important in the frictional behavior of two contact surfaces. In general, it has been found that friction increases with average roughness. The prediction of friction and stress/ ... -
DECIPHERING THE EFFECT OF CURRICULA ON THE PERCEPTION OF THIRD LEVEL ENGINEERING - A COMPARATIVE ANALYSIS
(2012)Recent PISA surveys have shown that Ireland’s relative ranking in Mathematics has fallen sharply, while Finland maintains its posit ion at the top of the international table. Simultaneously, ... -
Dielectric study of the electroclinic effect in the smectic-A phase
(American Physical Society, 1994)The dielectric properties of a smectic-A liquid crystal in the presence of a dc bias field are studied in the frequency range 100 Hz?1 MHz. It is shown that near the smectic-A?smectic-C* phase transition the relaxation ... -
End User Response to an Event Detection and Route Reconstruction Security System Prototype for use in Airports and Public Transport Hubs
(2016)Video surveillance is ex tensively used in many countries for security purposes, contributing to effective prevention, detection, and/or prosecution of crime and terrorism. Although its contribution ... -
ENGAGEMENT WITH SECOND LEVEL - DOES IT WORK?
(2012)Most Western economies are suffering from problems in attracting students to study Science, Engineering and Technology courses at university level. To address this demand shortage, and also with regard to current financial ... -
The Engineering Investigation of the Water Flow past the Butterfly Valve
(Trinity College Dublin. School of Engineering. Mechanical & Manufacturing Engineering, 2007)This paper presents a numerical simulation of flow past the butterfly valve in static and dynamic analysis using commercial fluid dynamics software FLUENT. In static analysis, the positions of the disk were set to be 0 ( ... -
Field-induced transformations in the biaxial order of non-tilted phases in a bent-core smectic liquid crystal
(Institute of Physics, 2010)The structural and electro-optic investigations of an achiral bent-core molecule in SmAPA phase, in which the polar directors in the neighboring layers are arranged anti-ferroelectrically, show that it undergoes transformation ... -
High dynamic velocity range particle image velocimetry using multiple pulse separation imaging
(2011)The dynamic velocity range of particle image velocimetry (PIV) is determined by the maximum and minimum resolvable particle displacement. Various techniques have extended the dynamic range, however flows with a wide velocity ... -
Microsecond linear optical response in the unusual nematic phase of achiral bimesogens
(2011)Some hydrocarbon linked mesogenic dimers are known to exhibit an additional nematic phase (N(x)) below a conventional uniaxial nematic (N(u)) phase. Although composed of non-chiral molecules, the N(x) phase is found to ... -
Nonlinear Frequency Scattering of Broadband Noise in Turbomachinery (AIAA 2010-3805)
(2010)Coherence based source analysis techniques can be used to identify the contribution of broadband noise sources in the exhaust of a gas turbine and hence enable the design of noise reduction devices. However, when the ... -
On the calculation of offshore wind turbine load spectra for fatigue design
(2018)The present work researches on the definition of the load spectra used for offshore wind turbine low SN slope materials’ fatigue design. Uncertainty in the sample sized used to scale fatigue life is analyzed for the tower ... -
PREDICTION OF ENGINEERING STUDENT PROGRESSION FROM ENTRANCE DATA
(2012)Most Western economies are suffering from problems in attracting students to study Science, Engineering and T echnology courses at university level. Concurrently, engineering programmes te nd to have higher dropout ...
