A Bayesian approach for estimating characteristic bridge traffic load effects
(2015)

Abstract:
Civil Engineering Research in Ireland, Belfast, UK, 28 -29 August, 2014
This paper investigates the use of Bayesian updating to improve estimates of characteristic bridge traffic loading. Over recent years the use Weigh-In-Motion technologies has increased hugely. Large Weigh-In-Motion databases are now available for multiple sites on many road networks. The objective of this work is to use data gathered throughout a road network to improve site-specific estimates of bridge loading at a specific Weigh-In-Motion site on the network. Bayesian updating is a mathematical framework for combining prior knowledge with new sample data. The approach is applied here to bridge loading using a database of 81.6 million truck records, gathered at 19 sites in the US. The database represents the prior knowledge of loading throughout the road network and a new site on the network is simulated. The Bayesian approach is compared with a non-Bayesian approach, which uses only the site-specific data,...

A Case Study in Modeling and Process Control: the Control of a Pilot Scale Heating and Ventilation System
(2006)
Mooney, Robin; O'Dwyer, Aidan
Abstract:
This paper details the control of a pilot scale laboratory heating and ventilation system. The system is represented in 2x2 multi-input, multi-output (MIMO) form. A process reaction curve identification technique was used to model (in first order lag plus delay - FOLPD - form) the flow process and temperature process portions of the system, over a range of operating conditions. Tests revealed that both processes were continuously non-linear. A gain scheduler with static decoupling was designed, using look-up tables, to continuously interpolate for the most suitable proportional-integral (PI) or proportional-integral-derivative (PID) controller settings and decoupler gains. The contribution of this paper is the careful application, using well-known techniques, of a complete controller design cycle for a laboratory scale system.

A Framework to Implement IoT Network Performance Modelling Techniques for Network Solution Selection
(2016)
Delaney, Declan T.; O'Hare, G. M. P. (Greg M. P.)
Abstract:
No single network solution for Internet of Things (IoT) networks can provide the required level of Quality of Service (QoS) for all applications in all environments. This leads to an increasing number of solutions created to fit particular scenarios. Given the increasing number and complexity of solutions available, it becomes difficult for an application developer to choose the solution which is best suited for an application. This article introduces a framework which autonomously chooses the best solution for the application given the current deployed environment. The framework utilises a performance model to predict the expected performance of a particular solution in a given environment. The framework can then choose an apt solution for the application from a set of available solutions. This article presents the framework with a set of models built using data collected from simulation. The modelling technique can determine with up to 85% accuracy the solution which performs the ...

A mechanistic model for oil recovery in a region of high oil droplet concentration from multiphasic fermentations
(2019)
Da Costa Basto, Rita M.; Casals, Maria P.; Mudde, Robert F.; van der Wielen, Luuk A.M.; Cuellar, Maria C.
Abstract:
Multiphasic fermentations where an organic phase is spontaneously formed or when it is added for product removal are commonly used for production of valuable compounds. The turbulent conditions and the presence of surface-active compounds (SACs) during fermentation create a stable emulsion difficult to separate. A gas bubble/oil droplet separation method has been proposed to break such emulsion. In this paper, we propose a mathematical model to describe oil/bubble interaction in a region of high oil droplet concentration. Model validation was performed using a synthetic emulsion and an emulsion from a fermentation broth. By applying the optimal parameters predicted by the model, a 6- and 3-times oil recovery improvement was reached for the synthetic emulsion and the fermentation broth, respectively. In conclusion, the proposed mechanistic model allowed to improve oil recovery in the existing laboratory set-up, and can be used to optimize the separation and recovery method at large s...

Computational micromechanics of fibre-reinforced polymers (FRPs) relies on the ability of the representative volume elements (RVEs) to take into account the different features that characterise the geometry of the material system under consideration. Fibre misalignment has been proven experimentally to have a significant effect on the mechanical properties at the macroscale, but is not currently taken into consideration in models at the individual fibre level, perhaps due to the difficulty in statistically characterising the fibre misalignment. In this work, an integrated approach is presented to measure and model fibre misalignments in FRPs. A computed tomography (CT) scan is used to identify the fibre geometry and statistically characterise the fibre misalignment angle distribution. Using a methodology recently developed by the authors, three-dimensional (3D) RVEs were gener...

A numerical investigation of spherical void growth in an elastic–plastic continuum
(2013)
Leonard, M.; Murphy, Neal; Karac, Aleksandar; et al.
Abstract:
Significant toughening of structural epoxy adhesives has been achieved with the addition of nano and micro-scale particles. However, the toughening mechanisms introduced by the addition of these particles is not very well understood. The ultimate aim of this research is to develop an understanding of the toughening mechanisms present and investigate the parameters which a ect the degree of toughening, i.e. particle size, particle volume fraction and particle distribution to guide future adhesives development. The current work examines the growth of a single void in an elastic-plastic material as a function of constraint and compares the results with the predictions of the classic Rice & Tracey model.

Abstract:
The full text of this article will not be available in ULIR until the embargo expires on the 29/11/2021
Tower systems are forecast to become the dominant CSP technology in the future due to the potential to achieve high working fluid temperatures, thereby enhancing thermodynamic efficiency in the power block and facilitating dispatchable electricity through thermal energy storage. The receiver links the solar collector field and power conversion cycle in a tower plant, and is therefore a critical component that requires careful consideration. Tubular receivers represent the most prominent in commercial scale applications, with many research efforts devoted to the characterisation and modelling of such concepts. This article compiles literature engaged in steady-state thermal and mechanical modelling of tubular solar receivers. The discussion outlines contrasting approaches adopted by various authors, while also detailing some important findings from their investigations. Recent ...

A review of the effect of prior inelastic deformation on high temperature mechanical response of engineering alloys
(2010)
Li, Dong-Feng; O'Dowd, Noel P.; Davies, Catrin M.; Nikbin, Kamran
Abstract:
In this review article, we examine the influence of prior deformation (prestrain) on the subsequent high temperature mechanical behaviour of engineering alloys. We review the observed effects at a macroscopic level in terms of creep deformation, creep rupture times and crack growth rates from a number of sources and a range of materials. Microstructural explanations for the observed macroscopic effects are also reviewed and constitutive models which incorporate the effect of prior deformation are examined. The emphasis in the paper is on engineering steels though reference is also made to non ferrous alloys

A Simulation-Based Decision Support System to Model Complex Demand Driven Heathcare Facilities
(2012)
Arisha, Amr; Thorwarth, Michael
Abstract:
Simulating healthcare processes is a sophisticated endeavor. Treatment processes and patient arrival patterns differ significantly in their statistical attributes and implicate a high degree of variability. In addition, there are several types of interconnected processes of medical staff involved that accompany a patient’s journey through the healthcare facility. Replicating this behavior with process flow models in a discrete event simulation model is highly complex and therefore difficult to create while maintaining a high degree of precision. A framework is thus introduced which delivers an algorithm that allows to implement Multiple Participant Pathway Modeling (MPPM) under the consideration of Flexible Resource Allocation (FRA). This framework is applied on an Irish Emergency Department (ED), the outcome of which is presented here. Results show that scenarios can be investigated which impact several different process flows with a high precision. This provides a solid base for b...

A structure design method for compliant parallel manipulators with actuation isolation
(2016)
Hao, Guangbo; Kong, Xianwen
Abstract:
Since precise linear actuators of a compliant parallel manipulator suffer from their inability to tolerate the transverse motion/load in the multi-axis motion, actuation isolation should be considered in the compliant manipulator design to eliminate the transverse motion at the point of actuation. This paper presents an effective design method for constructing compliant parallel manipulators with actuation isolation, by adding the same number of actuation legs as the number of the DOF (degree of freedom) of the original mechanism. The method is demonstrated by two design case studies, one of which is quantitatively studied by analytical modelling. The modelling results confirm possible inherent issues of the proposed structure design method such as increased primary stiffness, introduced extra parasitic motions and cross-axis coupling motions.

A two-stage examination of business innovation decision-making: evidence from Ireland
(2015)
Bourke, Jane; Jordan, Declan
Abstract:
This paper sheds light on how businesses make decisions regarding product and process innovation by comparing the power of one-stage and two-stage models to explain business-level innovation decision-making. The first, a one-stage model, represents the business as making a one-off choice between four discrete alternatives. These are not to innovate, to product innovate only, to process innovate only or to both product and process innovate. The second model, a two-stage model, represents the business as making an initial decision on whether or not to innovate. This approach facilitates analysis of business innovation as simultaneous and sequential processes and identification of the model which best explains innovation decision-making. The paper uses original business-level survey data from over 400 small and medium-sized enterprises in Ireland. The results suggest that a two-stage model of the innovation decision has a statistically significant advantage in predicting the innovation...

Advanced distribution network modelling with distributed energy resources
(2017)
O'Connell, Alison
Abstract:
The addition of new distributed energy resources, such as electric vehicles, photovoltaics, and storage, to low voltage distribution networks means that these networks will undergo major changes in the future. Traditionally, distribution systems would have been a passive part of the wider power system, delivering electricity to the customer and not needing much control or management. However, the introduction of these new technologies may cause unforeseen issues for distribution networks, due to the fact that they were not considered when the networks were originally designed.This thesis examines different types of technologies that may begin to emerge on distribution systems, as well as the resulting challenges that they may impose. Three-phase models of distribution networks are developed and subsequently utilised as test cases. Various management strategies are devised for the purposes of controlling distributed resources from a distribution network perspective. The aim of the ma...

An experimental and modelling study of the combustion of oxygenated hydrocarbons
(2014)
Gillespie, Fiona Rita
Abstract:
A chemical kinetic mechanism for the combustion of acetone has been developed and compared with a range of experimental data from the literature and with species concentration profiles measured in this study in the Princeton variable-pressure flow reactor. The current mechanism has been found to agree with the experimental data more accurately than the original mechanism. However, in the concentration profiles, ethylene and water are consistently over-predicted by the current mechanism. Ignition delay times of ethanol and dimethyl ether have been measured in the low-pressure shock tube at NUI, Galway at varying fuel concentrations, equivalence ratios and pressures. Laminar burning velocities of ethanol in air have been measured using the flat-flame burner at the Universite de Lorraine at 358 K and 1.0 atm. Reactions that influence the ignition delay times of ethanol and dimethyl ether include decomposition and hydrogen-abstraction reactions, while those influencing the laminar burni...

An integrated approach to trophic assessment of coastal waters incorporating measurement, modelling and water quality classification
(2013)
Hartnett, Michael; Nash, Stephen; Olbert, Agnieszka Indiana
Abstract:
Various protocols have been developed for trophic assessment of coastal waters but most incorporate single value compliance criteria for water quality parameters which, in reality, exhibit significant spatial variation. Application of these protocols generally requires the averaging of data recorded at discrete locations to obtain single values for comparison with compliance criteria; however, there is no guarantee that the averaged values are truly representative of overall water quality. The present approach to trophic assessment integrates measurement, remote sensing, flushing analysis and water quality modelling with the aim of identifying sub-regions in coastal waterbodies that demonstrate homogeneity. Averaged water quality data for these homogenous sub-regions should be more representative of the water quality in the sub-region as a whole making the assessment process more accurate. The integrated approach incorporates water quality classification criteria developed by the Ir...

Abstract:
The healthcare sector is a highly regulated environment that is subject to numerous constraints. Standards around medical protocol, medical device certification, and data protection ensure that the wellbeing and privacy of patients is protected during all encounters with the healthcare system. However, a gap has opened up between the need to meet these constraints, improve performance, and also deliver good patient experience. For example, the medical protocol for hypertension during pregnancy establishes a set of clinically validated treatment guidelines, but does not consider the unique nature of patient experience. We assert that design research principles can be used to create visual tools that pay homage to these constraints and performance improvement goals without compromising patient experience. In this paper, we describe such a tool that has been developed during a healthcare project using a human-centred design research approach. The integrated tool for patient journey map...

Abstract:
In this paper, the behaviour of a LSC doped with Near-Infrared Quantum Dots (NIR-QD) in an epoxy host material is modelled by a ray tracing algorithm under different iteration numbers. It is shown that by increasing the number of input rays in the system improving the accuracy of simulation and the QDs emission spectra. However, increasing the number of the rays has linearly increased simulation iterations, hence the simulation time. This challenge is overcome by optimizing the program by avoiding recalculations of parameters in the program which significantly reduces the volume of calculations; thus, simulation time. As a case in point, in a simulation run for 126000 rays, the simulation time was decreased from around 107 hours in the primary program to around only 3 hours in the optimized version. Furthermore, in the simulation for around 718000 rays, the optimized program achieved the simulation time of roughly 18 hours with higher accuracy . The ray-trace model predicted optic...

Abstract:
The push for carbon-free energy sources has helped encourage the development of the ocean renewable energy sector. As ocean renewable energy approaches commercial maturity, the industry must be able to prove it can provide clean electrical power of good quality for consumers. As part of the EU funded Open Sea Operating Experience to Reduce Wave Energy Cost (OPERA) project that is tasked with developing the wave energy sector, the International Electrotechnical Commission (IEC) developed electrical power quality standards for marine energy converters, which were applied to an oscillating water column (OWC). This was done both in the laboratory and in the real world. Precise electrical monitoring equipment was installed in the Mutriku Wave Power Plant in Spain and to an OWC emulator in the Lir National Ocean Test Facility at University College Cork in Ireland to monitor the electrical power of both. The electrical power generated was analysed for harmonic current distortion and the re...

As-cast grain size distribution prediction for grain refined castings via simulating free equiaxed dendrite transport during solidification
(2013)
Mirihanage, Wajira U.; Browne, David J.
Abstract:
In foundry practice, as-cast microstructure is a key concern. It is well accepted that gravitydriven transport processes have an influence on the final microstructure of shape cast components. A predictive model to simulate equiaxed solidification, which treats dendrite transport in the solidifying alloy melt, at low computational cost, is presented in this article. The non-equilibrium solidification model considers nucleation from industrial inoculants, growth and transport of the equiaxed dendrites. The motion of free dendrites is computed as the combined effects of sedimentation settling and transport of free dendrites by the liquid flow due to natural convection. When free dendrites become coherent at the latter stage of solidification, the equiaxed mush of coherent dendrites is assumed to demonstrate characteristics of a porous medium, until it becomes completely solid. Simulations are used to establish the sensitivity of the as-cast structure of Al-Si shape castings to the mag...

Aspen Plus Simulation of Biomass Gasification in a Steam Blown Dual Fluidised Bed
(2013)
Doherty, Wayne; Reynolds, Anthony; Kennedy, David
Abstract:
The efficient utilisation of biomass resources is of utmost importance. Biomass gasification offers much higher efficiencies than combustion. Gasification is a process in which a fuel is converted to a combustible gas (syngas). A dual fluidised bed gasifier known as the fast internally circulating fluidised bed (FICFB) was selected. It has been demonstrated at industrial scale and data is readily available for model validation. An Aspen Plus model was developed to simulate the FICFB gasifier. The model is based on Gibbs free energy minimisation and the restricted equilibrium method was used to calibrate it. The model has been validated and predicts syngas composition, heating value and cold gas efficiency (CGE) in very good agreement with published data. Important operating parameters such as gasification temperature (Tg), biomass moisture, steam to biomass ratio (STBR), air-fuel ratio and air and steam temperature were varied. Tg and STBR were found to have very strong influence on...

Assessment dynamic ratio for traffic loading on highway bridges
(2011)
Caprani, Colin C.; González, Arturo; Rattigan, Paraic; O'Brien, Eugene J.
Abstract:
The determination of characteristic bridge load effect is a complex problem. Usually, statistical extrapolation of simulated static load effects is used to derive a lifetime characteristic static load effect. However, when a vehicle crosses a bridge, dynamic interaction occurs which often causes a greater total load effect. This total load effect is related to the static load effect through a dynamic amplification factor (DAF). Specifications often recommend a conservative level for DAF, based on bridge length, number of lanes, and type of load effect only. Therefore significant improvements in the accuracy of this calculation are possible if a DAF, specific to the considered bridge, is applied. In this paper, the authors develop a novel method that considers site-specific bridge and traffic load conditions and allows for the reduced probability of both high static loading and high dynamic interaction occurring simultaneously. This approach utilises multivariate extreme value theory...

Abstract:
The aims of this study were to describe associations of time of year, and herd size with cow somatic cell count (SCC) for Irish, English, and Welsh dairy herds. Random samples of 497 and 493 Irish herds, and two samples of 200 English and Welsh (UK) herds were selected. Random effects models for the natural logarithm of individual cow test day SCC were developed using data from herds in one sub-dataset from each country. Data from the second sub-datasets were used for cross validation. Baseline model results showed that geometric mean cow SCC (GSCC) in Irish herds was highest from February to August, and ranged from 111,000 cells/mL in May to 61,000 cells/mL in October. For cows in UK herds, GSCC ranged from 84,000 cells/mL in February and June, to 66,000 cells/mL in October. The results highlight the importance of monitoring cow SCC during spring and summer despite low bulk milk SCC at this time for Irish herds. GSCC was lowest in Irish herds of up to 130 cows (63,000 cells/mL), a...
