Variations in travel time for N loading to groundwaters in four case studies in Ireland: Implications for policy makers and regulators

Variations in travel time for N loading to groundwaters in four case studies in Ireland: Implications for policy makers and regulators
(2009)
COXON, CATHERINE ELIZABETH
Abstract:
Mitigation measures to protect waterbodies must be implemented by 2012 to meet the requirements of the EU Water Framework Directive. The efficacy of these measures will be assessed in 2015. Whilst diffuse N pathways between source and receptor are generally long and complex, EU legislation does not account for differences in hydrological travel time distributions that may result in different water quality response times. The ?lag time? between introducing mitigation measures and first improvements in water quality is likely to be different in different catchments; a process that should be considered by policy makers and catchment managers. Many examples of travel time variations have been quoted in the literature but no Irish specific examples are available. Lag times based on initial nutrient breakthrough at four contrasting sites were estimated to a receptor 500 m away from a source. Vertical travel times were estimated using a combination of depth of infiltration calculations bas...

Part-time working in Ireland in a European context

Part-time working in Ireland in a European context
(1991)
DREW, EILEEN PATRICIA
Abstract:
The subject of part-time work is one which has become increasingly important in industrialized economies, most notably Norway, Sweden, United States, Canada, Denmark and the United Kingdom, where it accounts for a substantial and growing proportion of total employment. It has been noted that resort to part-time workers was generally a response to a shortage of available labour, particularly when it coincided with periods of economic boom. However the view that part-timers would be engaged at times of economic upturn and be among the first categories of workers to be let go at periods of recession has not been upheld during the last decade. It is now recognized that part-time working is no temporary practice. Rather it represents a growth segment of an otherwise static to falling labour force in many developed economies.

Real-time Collision Detection and Response using Sphere-trees

Real-time Collision Detection and Response using Sphere-trees
(1999)
O'SULLIVAN, CAROL; DINGLIANA, JOHN
Abstract:
In this paper we address the problem of collision detection and response in real-time animation systems. We describe an approach, which approximates objects using sphere-trees, and uses an interruptible detection algorithm to approximately test for collisions between them, trading accuracy for speed. A model of human visual perception of collisions is used to decide which collisions deserve more processing time. Collision processing is then scheduled to minimise the perceived inaccuracy within the time available. In response to such approximate collisions, a new adaptive collision response algorithm is presented, which also uses sphere-trees to approximate the appropriate response for colliding objects.

What are the limits to time series based recognition of semantic concepts?
(2016)
Wang, Peng; Sun, Lifeng; Yang, Shiqiang; Smeaton, Alan F.
Abstract:
Most concept recognition in visual multimedia is based on relatively simple concepts, things which are present in the image or video. These usually correspond to objects which can be identified in images or individual frames. Yet there is also a need to recognise semantic con- cepts which have a temporal aspect corresponding to activities or com- plex events. These require some form of time series for recognition and also require some individual concepts to be detected so as to utilise their time-varying features, such as co-occurrence and re-occurrence patterns. While results are reported in the literature of using concept detections which are relatively specific and static, there are research questions which remain unanswered. What concept detection accuracies are satisfactory for time series recognition? Can recognition methods perform equally well across various concept detection performances? What affecting factors need to be taken into account when building concept-based high-...

Real-time PCR detection of Dinophysis species in Irish coastal waters
(2010)
Kavanagh, S.; Brennan, C.; O’Connor, L.; Moran, S.; Salas, R.; Lyons, J.; Silke, J.; Maher, M.
Abstract:
Diarrhetic shellfish toxin-producing Dinophysis species occur in Irish coastal waters throughout the year. Dinophysis acuta and Dinophysis acuminata are the most commonly occurring species and are responsible for the majority of closures of Irish mussel farms. This study describes the development of a qualitative real-time polymerase chain reaction (PCR) assay for identification of D. acuta and D. acuminata in Irish coastal waters. DNA sequence information for the D1-D2 region of the large ribosomal sub-unit (LSU) was obtained, following single-cell PCR of D. acuta and D. acuminata cells isolated from Irish coastal locations. PCR primers and hybridization probes, specific for the detection of D. acuta, were designed for real-time PCR on the LightCycler™. The LightCycler™ software melt curve analysis programme determined that D. acuta was identified by a melt-peak at 61°C, while D. acuminata cells produced a melt peak at 48°C. The limit of detection of the real-time PCR assay was det...

Optimal Real-Time Predictive Control for Maximising the Power-Take-Off Efficiency of the WaveRAM Wave Energy Converter
(2018)
Signorelli, Christopher
Abstract:
The aim of this thesis is to develop a control strategy for optimising the power-take-off (PTO) efficiency of the newly developed WaveRAM (WRAM) wave energy converter. The three main research streams established to satisfy these requirements have been: 1) the development of a wave-to-wire numerical model of the WRAM and its PTO system; 2) the implementation of a real-time model predictive control (RT MPC) algorithm; and 3) the construction of a laboratory test rig, capable of emulating the behaviour of a sea-going device. Given that the WRAM is intended for deployment at sea in the near future, the control algorithm must be capable of operating in real-time. This has been the primary motivation of the second research stream, where portions of the model created in the first stream were used as the controlled plant. In order to verify the algorithm's performance prior to sea-deployment, the laboratory test facility from the third stream ensures that the algorithm can operate succ...

Parent-reported experience of using a real-time text messaging service for dental appointments for children and young people with autism spectrum conditions: a pilot study
(2018)
Holt, Samantha; Parry, Jennifer A.
Abstract:
Introduction: Children and young people (CYP) with autism spectrum conditions (ASCs) and their parents/carers find dental appointments stressful. Consultation with parents of CYP with ASC identified time spent in dental waiting areas as contributing to dental anxiety. Parents proposed waiting outside the dental practice until the clinician was ready could help mitigate anxiety. Aims: To evaluate a real‐time text messaging service (RTMS) to improve dental attendance experience for CYP with ASC. Methods: An RTMS was developed for use in the dental clinic. Parents/carers of 17 CYP with ASC (4 to 20 years) attending a Special Care Dental service were invited to share their dental experience and the impact of using the RTMS. Results: Parent experience suggests that time in waiting areas can increase anxiety in CYP with ASC. All parents viewed the RTMS as having a positive impact on CYP dental attendance experience. The majority believed that it reduced anxiety and enabled CYP to be more ...

A real-time and robust routing protocol for building fire emergency applications using wireless sensor networks
(2010)
Zeng, Yuanyuan; Sreenan, Cormac J.; Sitanayah, Lanny
Abstract:
Fire monitoring and evacuation for building environments is a novel application for the deployment of wireless sensor networks. In this context, real-time and robust routing is essential to ensure safe and timely building evacuation and the best application of fire fighting resources. Existing routing mechanisms for wireless sensor networks are not well suited for building emergencies, especially as they do not explicitly consider critical and rapidly changing network scenarios. In this paper, a novel real-time and robust routing protocol (RTRR) is presented for building fire emergency applications. It adapts to handle critical emergency scenarios and supports dynamic routing reconfiguration. Simulation results indicate that our protocol satisfies the criteria necessary to support building emergency scenarios.

Mechanism-based Inhibition: Deriving KI and kinact directly from Time-Dependent IC50 Values
(2009)
Krippendorff, Ben-Fillippo; Neuhaus, Roland; Lienau, Philip; Reichel, Andreas; Huisinga, Wilhelm
Abstract:
The potential of enzyme inhibition of a drug is frequently quantified in terms of IC50 values. While this is a suitable quantity for reversible inhibitors, concerns arise when dealing with irreversible, or mechanism-based inhibitors (MBI). IC50 values of MBI are time-dependent, causing serious problems when aiming at ranking different compounds with respect to their inhibitory potential. As a consequence, most studies and ranking schemes related to MBI rely on the inhibition constant (KI) and the rate of enzyme inactivation (kinact) rather than on IC50 values. In this article we derive a novel relation between potentially time-dependent IC50 values and KI, kinact parameters for different types of inhibition. This allows for direct estimation of KI and kinact values from time-dependent IC50 values, even without the need of additional pre-incubation experiments. The application of this approach is illustrated using a fluorimetric assay to access the drug-drug interaction potential ass...

24-Hour Electrical Load Data - A Time Series or a Set of Independent Points?
(2001)
Fay, Damien; Ringwood, John; Condon, Marissa; Kelly, Michael
Abstract:
The paper investigates whether a time series or a set of independent points is a more appropriate description of 24-hour Irish electrical load data. A set of independent points means that the load at each hour of the day is independent from the load at any other hour. The data is first split into 24 series, one for each hour of the day i.e. a 1am 2am 3am series etc. These are called parallel series. The linear cross-correlation's of the parallel series are used to indicate independence. While the loads at 9am and 6pm to 8pm appear independent the remaining loads are highly inter-correlated. This suggests that 24-hour electrical load data has a dual nature. Two techniques are used to test this hypothesis. The first technique models each parallel series using neural networks. This technique is found to be computationally expensive. The second technique uses a hybrid technique called the Multi Time Scale (MTS) technique. This models 24-hour electrical load data as a time series th...

Multi-frequency scale Gaussian regression for noisy time-series data.
(2006)
Seng Neo, Kian; Leithead, W.E.; Zhang, Yunong
Abstract:
Regression using Gaussian process models is applied to time-series data analysis. To extract from the data separate components with different frequency scales, the Gaussian regression methodology is extended through the use of multiple Gaussian process models. Fast and memory-efficient methods, as required by Gaussian regression to cater for large time-series data sets, are discussed. These methods are based on the generalised Schur algorithm and a procedure to determine the Schur decomposition of matrices, the key step to realising them, is presented. In addition, a procedure to appropriately initialise the Gaussian process model training is presented. The utility of the procedures is illustrated by application of a multiple Gaussian process model to extract separate components with different frequency scales from a 5000-point time-series data set with gaps.

Computing Upper-bounds of the Minimum Dwell Time of Linear Switched Systems via Homogeneous Polynomial Lyapunov Functions
(2010)
Chesi, D.; Colaneri, P.; Geromel, J.C.; Middleton, R.; Shorten, Robert N.
Abstract:
This paper investigates the minimum dwell time for switched linear systems. It is shown that a sequence of upper bounds of the minimum dwell time can be computed by exploiting homogeneous polynomial Lyapunov functions and convex optimization problems based on linear matrix inequalities (LMIs). This sequence is obtained by adopting two possible representations of homogeneous polynomials, one based on Kronecker products, and the other on the square matrix representation (SMR). Some examples illustrate the use and the potentialities of the proposed approach. It is also conjectured that the proposed approach is asymptotically nonconservative, i.e. the exact minimum dwell time is obtained by using homogeneous polynomials with sufficiently large degree.

Forecasting Electrical Load Using a Multi-time-scale Approach
(1999)
Ringwood, John; Murray, F.T.
Abstract:
This paper describes the application of a multi-time-scale technique to the modelling and forecasting of short-term electrical load. The multi-time-scale technique is based on adjusting the underlying short sampling period forecast time series with specific target points and possible aggregated demand. This allows not only improvement of the short sampling period forecast, but also focuses on weighting the accuracy of the forecast at certain critical points e.g. the overnight minimum and daily peaks. Various model types may be utilised at the upper level (forecating the aggregated consumption and target points at daily level), including intelligent models such as neural and fuzzy models, but the base model is currently restricted to a linear form. Results for the Irish national electrical grid demonstrate the effectiveness of the technique.

Empowering Children Through Circle Time: An Illumination of Practice
(2011)
Collins, Bernie
Abstract:
The focus of the research is circle time, a widely used method in Irish primary schools. It involves children sitting in a circle with their teacher using method-specific techniques and strategies to promote self-esteem, develop skills and support positive classroom relationships. The theoretical and conceptual framework adopted has empowerment of children as its central focus, and is supported by theories of self-esteem, emotional intelligence, and voice and participation theory. Learning and counselling theories also inform the research. The rise of circle time historically is documented against a backdrop of curricular and social changes in Ireland. These include a psychological turn in educational and societal discourse, a move towards inclusive and rights-based education, and an orientation towards personal development evident in recent reviews of the SPHE Curriculum (1999). The current research is prompted and informed by a review of research on circle time which suggests that...

Handling positional uncertainty in a real-time bus tracking system
(2010)
Shalaik, Bashir; Winstanley, Adam C.
Abstract:
Automatic Vehicle Location (AVL) systems are increasingly being used by transit agencies for the real time monitoring of their vehicles. AVL systems can be used to improve the service given to passengers by using informat8ion on the current position of buses to maintain headways or increase reliability by improved operational control and provide an estimate of as to the arrival time of the next bus at the stop. In real-time bus tracking systems, some positional uncertainty is usually associated with eh location of buses in service that are tracked using a locational device such as a Global Positioning System (GPS) receiver. Rather than raw coordinates, the location is usually better understood in terms of the landmarks along the route, particularly the named stop. Three prediction models have been implemented to estimate the location of vehicles on bus routes. Analysis indicates that one based on mining historical data for patterns gives more accurate results than regression an...

Short-Term Wave Forecasting with AR models in Real-Time Optimal Control of Wave Energy Converters
(2010)
Fusco, Francesco; Ringwood, John
Abstract:
Time domain control of wave energy converters requires knowledge of future incident wave elevation in order to approach conditions for optimal energy extraction. Autoregressive models revealed to be a promising approach to the prediction of future values of the wave elevation only from its past history. Results on real wave observations from different ocean locations show that AR models allow to achieve very good predictions for more than one wave period in the future if the focus is put on low frequency components, which are the most interesting from a wave energy point of view. For real-time implementation, however, the lowpass filtering introduces an error in the wave time series, as well as a delay, and AR models need to be designed so to be as robust as possible to these errors.

Abstract:
Long-term in-vivo electrochemistry (LIVE) enables real-time monitoring and measurement of brain metabolites. In this study we have simultaneously obtained blood oxygenation level dependent (BOLD) fMRI and amperometric tissue O2 data from rat cerebral cortex, during both increases and decreases in inspired O2 content. BOLD and tissue O2 measurements demonstrated close correlation (r=0.7898) during complete (0%) O2 removal, with marked negative responses occurring ca. 30 s after the onset of O2 removal. Conversely, when the inspired O2 was increased (50, 70 and 100% O2 for 1 min) similar positive rapid changes (ca. 15 s) in both the BOLD and tissue O2 signals were observed. These findings demonstrate, for the first time, the practical feasibility of obtaining real-time metabolite information during fMRI acquisition, and that tissue O2 concentration monitored using an O2 sensor can serve as an index of changes in the magnitude of the BOLD response. As LIVE O2 sensors can be used in awa...

Real-Time Detection of Musical Onsets with Linear Prediction and Sinusoidal Modelling
(2011)
Glover, John C.; Lazzarini, Victor; Timoney, Joseph
Abstract:
Real-time musical note onset detection plays a vital role in many audio analysis processes, such as score following, beat detection and various sound synthesis by analysis methods. This paper provides a review of some of the most commonly used techniques for real-time onset detection. We suggest ways to improve these techniques by incorporating linear prediction, as well as presenting a novel algorithm for real-time onset detection using sinusoidal modelling. We provide comprehensive results for both the detection accuracy and the computational performance of all of the described techniques, evaluated using Modal, our new open source library for musical onset detection, which comes with a free database of samples with hand-labelled note onsets.

Discrete-Time Modelling of the Moog Sawtooth Oscillator Waveform

Abstract:
Discrete-time modelling strategies of analogue Moog sawtooth oscillator waveforms are presented. Two alternative approaches suitable for real-time implementation are proposed, one modelling the analogue waveform in time domain using phase distortion synthesis and another matching the spectrum of an existing antialiasing sawtooth oscillator to the corresponding analogue spectrum using a first-order IIR post-equalising filter. A parameter estimation procedure for both approaches is explained and performed. Performance evaluation using polynomial fits for the estimated parameters is carried out, and good matches between the model outputs and recorded waveforms are obtained. The best match of the tested algorithms is produced by the phase distortion model and by post-equalising the fourth-order B-spline bandlimited step function sawtooth oscillator.

Design Considerations for Time-Slotted LoRa(WAN)

Design Considerations for Time-Slotted LoRa(WAN)
(2020)
Zorbas, Dimitrios
Abstract:
One of the most common issues in wireless networks is the problem of increasing the network capacity by alleviating or eliminating collisions with the minimum possible cost. The combination of time division protocols together with efficient slot allocation mechanisms is an effective way to achieve scalability and provide high reliability. In this paper, I describe the parameters that must be taken into account when designing LoRa(WAN)-based time-slotted protocols. I show that the LoRaWAN case differs from any other synchronous wireless solution mainly due to the characteristics of the LoRa physical layer and the regional radio duty cycle restrictions. I also propose a frame structure which has been adopted during the implementation of a time-slotted LoRa approach.

Estimating missing data in hierarchical space-time series with a short temporal extent
(2014)
Charlton, Martin; Brunsdon, Chris; Cahalane, Conor; Pforte, Lars
Abstract:
A challenging problem exists in the estimation of missing space-time data where the time series are relatively short, and the space series belong to a spatial hierarchy. An example is provided by the population estimates for regions belonging to the NUTS hierarchy which are available from the EUROSTAT data portal. The table demo_r_gind3 provides estimates of the population of NUTS0/1/2/3 regions at the 1st January 2000…2012 inclusive. Inspection of the table reveals that estimates are missing for 2000-2003 for two of the five NUTS3 regions in the NUTS2 region of Liège. There are other instances of missing data at NUTS3 where there are data for the corresponding higher level NUTS regions. The EUROSTAT table demo_r_d2jan provides estimates of the population on the 1st January for a longer time period, 1990…2012 inclusive, but these are only to NUTS2. Again, there is missing data. The question then arises as to whether it is possible to estimate the missing series. The NUTS2 values act...

Abstract:
This paper discusses the estimation of process parameters and ti me delay, in a Smith predictor structure, using gradient algorithms in the time domain. A number of estimation algorithms are outlined and applied in simulation to the estimation of the parameters of an appropriate process model. An analytical exploration of the technique is also provided.

Time as a circular spectrum and the retrospective device in Gustav Mahler’s Symphony no. 3 (1895-1896)
(2009)
Lee, Jennifer
Abstract:
The function of this chapter is to examine Mahler’s philosophical concept of time and the embodiment of this within the programmatic and structural model of his six-movement Symphony no. 3. This chapter shall argue that the composer’s newfound concept of time was borne out of Friedrich Nietzsche’s fundamental doctrine in his book Also Sprach Zarathustra1 (Thus Spoke Zarathustra) of 1885, from which Mahler drew directly in the fourth movement of his third symphony. It must be stated at this initial stage, however, that the contextual significance of Nietzsche’s work extends far beyond the borders of the fourth movement, instead radiating from this crucial midpoint in both directions and acting as the central anchor from which all contributory philosophical expressions in the symphony evolve. The subject of Mahler’s concept and treatment of time with regard to Nietzschean principals is but one of the ingredients exhibiting a contextual and often disguised correlation between the liter...

Multi-Channel Audio Time-Scale Modification
(2005)
Dorran, David; Lawlor, Bob; Coyle, Eugene
Abstract:
Phase vecoder based approaches to audio time-scale modification introduce a reverberant artefact into the time scaled output. Recent techniques have been developed to reduce the presence of this artefact; however, these techniques have the effect of introducing additional issues relating to their application to multi-channel recordings. This paper addresses these issues by collectively analysing all channels prior to time-scaling each individual channel.

Married Women in the Irish Part-time Labour Market
(1998)
Doris, Aedin
Abstract:
This paper uses an econometric analysis of the 1987 Economic and Social Research Institute household survey data to assess the sources of the growth which has occurred in parttime employment in the last decade. The models used allow both for the possibility that the hours of work choice is a discrete one, and for the influence of the demand side of the labour market on a woman's choice between part-time and full-time work. The results confirm the impression gained from descriptive statistics that the growth in part-time employment has been supply-led, but that the growth of the Services sector has facilitated this increase.
