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, ... -
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 ( ... -
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 ... -
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 ... -
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 ... -
Quantification of Subsurface Damage in a Brittle Insulating Ceramic by Three-Dimensional Focused Ion Beam Tomography
(2011)In this study, we present a fully automated method to investigate and reconstruct the three-dimensional crack structure beneath an indent in a highly insulating material. This work concentrates on issues arising from a ... -
Study of Parallel implementation of Computational codes
(Trinity College Dublin. School of Engineering. Mechanical & Manufacturing Engineering, 2008-11-05)The use of computers to solve scientific problems is abundant and almost a need of the day. As the complexity of the problems increased, the need to get fast and accurate results has also taken an altogether different ... -
Technique to Analyze Characteristics of Turbomachinery Broadband Noise Sources (AIAA 2010-3979)
(2010)In this paper an experimental technique for the decomposition of broadband ducted sound fields into their mode constituents is applied to two laboratory scale experimental setups. The broadband mode analysis technique ... -
The Use of CFD for Investigating Fluidelastic Instability in Tube Arrays
(Trinity College Dublin. School of Engineering. Mechanical & Manufacturing Engineering, 2007)There are several applications of tube arrays subject to cross flow in the industry, mostly for heat exchanging. These tubes are subject to forces arising due to the flow, and under certain conditions they can experience ... -
Very large fMRI study using the IMAGEN database: sensitivity - specificity and population effect modelling in relation to the underlying anatomy
(2012)In this paper we investigate the use of classical fMRI Random Effect (RFX) group statistics when analysing a very large cohort and the possible improvement brought from anatomical information. Using 1326 subjects from the ...
