Smooth And Peaked Solitons Of The Camassa-Holm Equation And Applications, Darryl Holm, Rossen Ivanov Jul 2011

Smooth And Peaked Solitons Of The Camassa-Holm Equation And Applications, Darryl Holm, Rossen Ivanov

Articles

The relations between smooth and peaked soliton solutions are reviewed for the Camassa- Holm (CH) shallow water wave equation in one spatial dimension. The canonical Hamiltonian formulation of the CH equation in action-angle variables is expressed for solitons by using the scattering data for its associated isospectral eigenvalue problem, rephrased as a Riemann- Hilbert problem. The momentum map from the action-angle scattering variables T∗(TN) to the flow momentum (X∗) provides the Eulerian representation of the N-soliton solution of CH in terms of the scattering data and squared eigenfunctions of its isospectral eigenvalue problem. The …


A Simple Ultrasensitive Displacement Sensor Based On A High Bend Loss Single-Mode Fibre And A Ratiometric Measurement System, Pengfei Wang, Gilberto Brambilla, Yuliya Semenova, Qiang Wu, Gerald Farrell Jul 2011

Royal Pomp: Viceregal Celebrations And Hospitaity In Georgian Dublin, Máirtín Mac Con Iomaire, Tara Kellaghan Jul 2011

Royal Pomp: Viceregal Celebrations And Hospitaity In Georgian Dublin, Máirtín Mac Con Iomaire, Tara Kellaghan

Articles

During the successive reigns of the Hanoverian kings in England (1714-1830), a total of thirty-seven different viceroys were sent to Ireland as representatives of the British Crown (Table 1). The position of viceroy (also referred to as lord-lieutenant) was awarded as a matter of political exigency, but the viceroy’s role was one of social as much as political significance. The viceroy and his vicereine played the roles of the British monarchs in absentia, and the Protestant minority ruling class, often referred to as the Ascendancy, expected the viceregal court at Dublin Castle to not merely mirror, but to outshine that …


Study Of The Shrinkage Caused By Holographic Grating Formation In Acrylamide Based Photopolymer Film, Mohesh Moothanchery, Izabela Naydenova, Vincent Toal Jun 2011

Study Of The Shrinkage Caused By Holographic Grating Formation In Acrylamide Based Photopolymer Film, Mohesh Moothanchery, Izabela Naydenova, Vincent Toal

Articles

We study the shrinkage in acrylamide based photopolymer by measuring the Bragg detuning of transmission diffraction gratings recorded at different slant angles and at different intensities for a range of spatial frequencies. Transmission diffraction gratings of spatial frequencies 500, 1000, 1500 and 2000 lines/mm were recorded in an acrylamide based photopolymer film having 60 ± 5 μm thickness. The grating thickness and the final slant angles were obtained from the angular Bragg selectivity curve and hence the shrinkage caused by holographic recording was calculated. The shrinkage of the material was evaluated for three different recording intensities 1, 5 and 10 …


Budget Allocation Formulas: Magic Or Illusion?, Roger Cross Jun 2011

Budget Allocation Formulas: Magic Or Illusion?, Roger Cross

Articles

Budget allocation formulas claim objectivity, and hence fairness. But factors composing the formula are limited to supply, demand, and cost. Attempts to correct for this imbalance of empirical data like usage have led to the use of weighted values in the formulas. This paper seeks to argue that assigning “weight” in a formula introduces value judgments and subjectivity, leaving only the misplaced illusion of objectivity.


The Current State Of Cooking In Ireland: The Relationship Between Cooking Skills And Food Choice, Máirtín Mac Con Iomaire, John Lydon Jun 2011

The Current State Of Cooking In Ireland: The Relationship Between Cooking Skills And Food Choice, Máirtín Mac Con Iomaire, John Lydon

Articles

This research investigated the attitudes of Irish people to food to ascertain whether the acquisition of cooking skills influences food choice. Caraher et al. (1999) report on the state of cooking in England noted that changing lifestyles has had a significant impact upon the demand of food offerings and on the variance of domestic cooking skills. Caraher et al. (1999) found that cooking skills play an important part in healthy eating as a vehicle for lower-paid people to achieve a healthy diet and is an essential life-skill. While these discourses advance, the deficiency of inherently Irish empirical data contributed to …


Us Fda Releases Final Rule On Medical Device Data Systems:What Does This Mean For Device Manufacturers, Martin Mchugh, Fergal Mccaffery, Valentine Casey Jun 2011

Us Fda Releases Final Rule On Medical Device Data Systems:What Does This Mean For Device Manufacturers, Martin Mchugh, Fergal Mccaffery, Valentine Casey

Articles

On 16 April 2011, the US Food and Drug Administration’s (FDA’s) final rule on medical device data systems (MDDSs) came into force. This rule attempts to remove the uncertainty surrounding the safety classification of certain information technology systems used in healthcare. Devices that now meet the criteria of being an MDDS are classified as Class I (general controls). However, this final ruling explicitly precludes specific software applications that meet the definition of an MDDS, such as electronic health record applications and computerised physician order entry applications, as being beyond the scope of an MDDS. Similarly, ambiguity still remains surrounding mobile …


Willpower Taxes, Lee Anne Fennell Jun 2011

Willpower Taxes, Lee Anne Fennell

Articles

Self-control and related concepts appear regularly in tax discussions, but often they are invoked hazily or blurred together with other aspects of choice over time. Despite the evident relevance of willpower to consumption patterns, wealth accumulation, and, ultimately, well-being, there is no consensus about whether and how heterogeneity along this dimension should factor into tax policy. There is support in the tax literature for such divergent responses as funneling more resources to low-willpower people, penalizing them for their lapses, and limiting their choices. Whether we should follow one of these approaches, or some other approach entirely, requires a careful analysis …

Building A World-Class System In Ireland’S Financial Crisis, Ellen Hazelkorn Jun 2011

Building A World-Class System In Ireland’S Financial Crisis, Ellen Hazelkorn

Articles

Irish higher education faces particular difficulties given the severity of its economic crisis. Like other countries, it is engaged in significant system restructuring coupled with managed policy direction. Where Ireland does differ is in its emphasis on a 'whole of country strategy' and commitment that teaching and research go hand-in-hand. This paper looks at the fortunes and mis-fortunes of Irish higher education.


The Police Gamesmanship Dilemma, Mary D. Fan Jun 2011

The Police Gamesmanship Dilemma, Mary D. Fan

Articles

Police gamesmanship poses a recurring regulatory challenge for constitutional criminal procedure, leading to zigzags and murky zones in the law such as the recent rule shifts regarding searches incident to arrest and interrogation. Police gamesmanship in the “competitive enterprise of ferreting out crime” involves tactics that press on blind spots, blurry regions or gaps in rules and remedies, undermining the purpose of the protections. Currently, courts generally avoid peering into the Pandora’s Box of police stratagems unless the circumvention of a protection becomes too obvious to ignore and requires a stopgap rule-patch that further complicates the maze of criminal procedure. …


Potential Water Quality Changes Due To Corn Expansion In The Upper Mississippi River Basin, Silvia Secchi, Philip W Gassman, Manoj Jha, Lyubov Kurkalova, Catherine L Kling Jun 2011

Potential Water Quality Changes Due To Corn Expansion In The Upper Mississippi River Basin, Silvia Secchi, Philip W Gassman, Manoj Jha, Lyubov Kurkalova, Catherine L Kling

Articles

While biofuels may yield renewable fuel benefits, there could be downsides in terms of water quality and other environmental stressors, particularly if corn is relied upon exclusively as the feedstock. The consequences of increased corn production will depend importantly on where (and how) the additional corn is grown, which, in turn, depends on the characteristics of land and its associated profitability. Previous work has relied on rules of thumb for allocating land to increased acreage based on historical land use or other heuristics. Here, we advance our understanding of these phenomena by describing a modeling system that links an economics-driven …

Articles

This paper presents a validated TRNSYS model for forced circulation solar water heating systems used in temperate climates. The systems consist of two flat plate collectors (FPC) and a heat pipe evacuated tube collector (ETC) as well as identical auxiliary components. The systems were fitted with an automated unit that controlled the immersion heaters and hot water demand profile to mimic hot water usage in a typical European domestic dwelling. The main component of the TRNSYS model was the Type 73 FPC or Type 538 ETC. A comparison of modelled and measured data resulted in percentage mean absolute errors for …


Can The Use Of Clickers Or Continous Assessment Motivate Critical Thinking?: A Case Study Based On Corporate Finance Students, Lucia Morales Jun 2011

Can The Use Of Clickers Or Continous Assessment Motivate Critical Thinking?: A Case Study Based On Corporate Finance Students, Lucia Morales

Articles

This study explores the use of clickers as a tool to support, encourage and motivate critical thinking in higher education students. A case study was carried out with a cohort of undergraduate students undertaking the BSc. in Accounting and Finance during the academic year 2009/10, were corporate finance was a major component. Since the students in this sample had previously demonstrated passivity during their corporate finance classes, it was proposed that clickers would help motivate them to participate during face to face sessions. Previous research on the use of clickers shows evidence that this tool has a positive effect on …


Printed Circularly-Polarized Antenna With Ultra-Wide Axial-Ratio Bandwidth, Xiulong Bao, Max Ammann Jun 2011

Printed Circularly-Polarized Antenna With Ultra-Wide Axial-Ratio Bandwidth, Xiulong Bao, Max Ammann

Articles

A circularly polarised printed dipole-like antenna employing asymmetrical arms and an orthogonal slit in the ground plane is presented. It is fed by a stepped microstrip line which connects to the shorter arm. By utilising surface currents on the asymmetrical arms and the orthogonal feedline structure, circular polarisation is realised. Experimental and numerical data are in agreement and the measured results show a fractional impedance bandwidth of 41.3% (1.77–2.69 GHz) and a wide axial-ratio bandwidth of 38.4% (1.81–2.67 GHz).

Maternal And Infant Nutritional Supplementation Practices In Ireland: Implications For Clinicians And Policymakers, Roslyn Tarrant, Margaret Sheridan-Pereira, Roberta Mccarthy, Katherine Younger, John Kearney

Articles

This prospective Irish observational study examined maternal and infant nutritional supplement use. From an initial sample of 539 mothers recruited from the Coombe Women and Infants University Hospital in Dublin (during 2004-2006), 450 eligible mothers werefollowed up at 6 weeks and 6 months postpartum. Only 200 women (44.4%) complied with peri-conceptional folic acid at therecommended time with strong social patterning associated with its uptake. Almost 10% of the sample (n=44) consumed acombined multivitamin and mineral supplement during pregnancy. A vitamin D-containing supplement was provided to only 5 (1.1%)and 15 (3.3%) infants at 6 weeks and 6 months, respectively. A national …


Deportation Is Different, Peter L. Markowitz Jun 2011

Deportation Is Different, Peter L. Markowitz

Articles

Over one hundred years ago, the Supreme Court emphatically declared that deportation proceedings are civil, not criminal, in nature. As a result, none of the nearly 400,000 individuals who were deported last year enjoyed any of the constitutional protections afforded to criminal defendants under the Sixth or Eighth Amendments. Among those 400,000 were numerous detained juveniles and mentally ill individuals who, as a result of the civil designation, were forced to navigate the labyrinth of immigration law alone, without appointed counsel. Others were lawul permanent residents who had pled guilty to minor offenses upon the correct advice of counsel that …


A Rheological Model Of The Dynamic Behaviour Of Magnetorheological Elastomers, Lin Chen, Stephen Jerrams Jun 2011

A Rheological Model Of The Dynamic Behaviour Of Magnetorheological Elastomers, Lin Chen, Stephen Jerrams

Articles

A rheological model is described that was developed to simulate the dynamic behaviour of magnetorheological elastomers (MREs). The viscoelasticity of the polymer composite, magnetic field induced properties and interfacial slippage between the matrix and particles were modelled by analogy with a standard linear solid model, a stiffness variable spring and a spring-Coulomb friction slider respectively. The loading history and rate dependent constitutive relationships for MREs were derived from the rheological model. The hysteresis loop from shear strain - shear stress plots, which determines the shear modulus and loss factor, were obtained from substituting cyclic loading into these constitutive relationships. The …

The study uses performance in the assessment task, student feedback drawn from survey questionnaires and a …


An Evaluation Of The Eeg Alpha-To-Theta And Theta-To-Alpha Band Ratios As Indexes Of Mental Workload, Bujar Raufi, Luca Longo May 2011

An Evaluation Of The Eeg Alpha-To-Theta And Theta-To-Alpha Band Ratios As Indexes Of Mental Workload, Bujar Raufi, Luca Longo

Articles

Many research works indicate that EEG bands, specifically the alpha and theta bands, have been potentially helpful cognitive load indicators. However, minimal research exists to validate this claim. This study aims to assess and analyze the impact of the alpha-to-theta and the theta-to-alpha band ratios on supporting the creation of models capable of discriminating self-reported perceptions of mental workload. A dataset of raw EEG data was utilized in which 48 subjects performed a resting activity and an induced task demanding exercise in the form of a multitasking SIMKAP test. Band ratios were devised from frontal and parietal electrode clusters. …


Studies Of Shrinkage As A Result Of Holographic Recording In Acrylamide Based Photopolymer Film, Mohesh Moothanchery, Izabela Naydenova, Vincent Toal May 2011

Studies Of Shrinkage As A Result Of Holographic Recording In Acrylamide Based Photopolymer Film, Mohesh Moothanchery, Izabela Naydenova, Vincent Toal

Articles

We studied the shrinkage in acrylamide-basedphotopolymer by measuring the Bragg detuning of transmission diffraction gratings recorded at different slant angles and at different intensities. Transmission diffraction gratings of spatial frequency 1000 lines/mm were recorded in an acrylamide-based photopolymer film having 60 ± 5 μm thickness. We have obtained the grating thickness and the final slant angles from the Bragg curve and hence calculated the shrinkage caused by holographic recording. The shrinkage of the material was evaluated for three different recording intensities 1, 5 and 10 mW/cm2, while the total exposure energy was kept constant at 80 mJ/cm2. From the experimental …


Woodland Expansion's Influence On Belowground Carbon And Nitrogen In The Great Basin U.S., Benjamin M. Rau, Dale W. Johnson, Robert R. Blank, Robin J. Tausch, Bruce A. Roundy, Richard F. Miller, Todd G. Caldwell, Annmarie Lucchesi May 2011

Woodland Expansion's Influence On Belowground Carbon And Nitrogen In The Great Basin U.S., Benjamin M. Rau, Dale W. Johnson, Robert R. Blank, Robin J. Tausch, Bruce A. Roundy, Richard F. Miller, Todd G. Caldwell, Annmarie Lucchesi

Articles

Vegetation changes associated with climate shifts and anthropogenic disturbance can have major impacts on biogeochemical cycling and soils. Much of the Great Basin, U.S. is currently dominated by sagebrush (Artemisia tridentate (Rydb.) Boivin) ecosystems. Sagebrush ecosystems are increasingly influenced by pinyon (Pinus monophylla Torr. & Frém and Pinus edulis Engelm.) and juniper (Juniperus osteosperma Torr. and Juniperus occidentalis Hook.) expansion. Some scientists and policy makers believe that increasing woodland cover in the intermountain western U.S. offers the possibility of increased organic carbon (OC) storage on the landscape; however, little is currently known about the distribution of OC …

Humidity Sensor Based On A Single-Mode Hetero-Core Fiber Structure, Qiang Wu, Yuliya Semenova, Jinesh Mathew, Pengfei Wang, Gerald Farrell May 2011

Humidity Sensor Based On A Single-Mode Hetero-Core Fiber Structure, Qiang Wu, Yuliya Semenova, Jinesh Mathew, Pengfei Wang, Gerald Farrell

Articles

Using a small-core single-mode fiber (SCSMF), a novel relative humidity (RH) sensor based on an SMF28-SCSMFSMF28 fiber structure was proposed in this paper. By depositing a humidity sensitive material, such as poly (ethylene oxide) (PEO) on the bare SCSMF fiber, the proposed structure can act as an RH sensor with high sensitivity. Experiments demonstrated that the proposed RH sensor with PEO coating can achieve a sensitivity of 430nm per relative humidity unit (RHU) in the RH range from 80% to 83% RH and a sensitivity of 50nm per RHU in the RH range from 83% to 95% RH.

Political History After The Cultural Turn., Steven Pincus, William J. Novak May 2011

Political History After The Cultural Turn., Steven Pincus, William J. Novak

Articles

Traditional political history is dead and is still dying. Over two decades ago, Lynn Hunt observed, "Social history has ovenaken political history as the most important area of research in history." The proponents of the new social history called for a broader, bottom-up, and more sociological account of the past. These scholars turned to historical sociology, social theory, as well as new empirical, socialscience methodologies in creating a fresh approach to history. More recently, of course, cultural history has ovenaken social history as the historical subdiscipline in which most doctoral research is conducted. While literary theory has played an important …


Optimisation Of Accelerated Solvent Extraction Of Antioxidant Compounds From Rosemary (Rosmarinus Officinalis L.), Marjoram (Origanum Majorana L.) And Oregano (Origanum Vulgare L.) Using Response Surface Methodology, M. Hossain, Catherine Barry-Ryan, Ana Belen Martin-Diana, N. Brunton May 2011

Articles

The present study optimised the accelerated solvent extraction (ASE) conditions (Dionex ASE® 200, USA) to maximise the antioxidant capacity of the extracts from three spices of Lamiaceae family; rosemary, oregano and marjoram. Optimised conditions with regard to extraction temperature (66–129 °C) and solvent concentration (32–88% methanol) were identified using response surface methodology (RSM). For all three spices results showed that 129 °C was the optimum temperature in order to obtain extracts with high antioxidant activity. Optimal methanol concentrations with respect to the antioxidant activity of rosemary and marjoram extracts were 56% and 57% respectively. Oregano showed a different response to …
