Using Higher Ionization States To Increase Coulomb Coupling In An Ultracold Neutral Plasma, M. Lyon, Scott D. Bergeson, A. Diaw, M. S. Murillo

Faculty Publications

We report measurements and simulations of the time-evolving rms velocity distribution in an ultracold neutral plasma. A strongly coupled ultracold neutral Ca⁺ plasma is generated by photoionizing laser-cooled atoms close to threshold. A fraction of these ions is then promoted to the second ionization state to form a mixed Ca⁺-Ca²⁺ plasma. By varying the time delay between the first and the second ionization events, a minimum in ion heating is achieved. We show that the Coulomb strong-coupling parameter Γ increases by a factor of 1.4 to a maximum value of 3.6. A pure Ca²⁺ plasma …

Thermal Buckling Analysis Of Axially Loaded Columns Of Thin-Walled Open Section With Nonuniform Sectional Properties, Shanshan Cheng, Qi Wu Yan, Long Yuan Li, Boksun Kim

School of Engineering, Computing and Mathematics

This paper presents an analytical study on the thermal buckling analysis of axially loaded columns of thin-walled open section with nonuniform sectional properties. Obtained herein are critical loads related to flexural, torsional and flexural-torsional buckling of an I-section column subjected to an axial compressive load applied at the geometric centroid, and under linearly varied non-uniform temperature distribution scenarios. The analysis is accomplished using traditional energy methods. The influences of thermal strain, nonuniform distribution of pre-buckling stresses, and variation of pre-buckling stresses along the longitudinal axis of the column on critical buckling loads are examined. The present results highlight the importance …

Investigating Some Technical Improvements To Glueball Calculations, B Lucini, C Mcneile, A Rago

School of Engineering, Computing and Mathematics

We briefly discuss some issues concerning including the pseudoscalar glueball interpolating operators into the variational basis for computing the masses of the h and h0 mesons. As a start we present some preliminary results for the correlators from pseudoscalar glueball operators on nf = 2+1+1 twisted mass gauge configurations. Preliminary results for the effect of open boundary conditions on the masses of three glueballs computed in quenched QCD are presented. The statistics of glueball correlators are briefly discussed.

The Density Of States Approach At Finite Chemical Potential: A Numerical Study Of The Bose Gas., R Pellegrini, L Bongiovanni, K Langfeld, B Lucini, A Rago

School of Engineering, Computing and Mathematics

Recently, a novel algorithm for computing the density of states in statistical systems and quantum field theories has been proposed. The same method can be applied to theories at finite density affected by the notorious sign problem, reducing a high-dimensional oscillating integral to a more tractable one-dimensional one. As an example we applied the method to the relativistic Bose gas.

Video Content-Based Qoe Prediction For Hevc Encoded Videos Delivered Over Ip Networks, Louis Anegekuh

School of Engineering, Computing and Mathematics Theses

The recently released High Efficiency Video Coding (HEVC) standard, which halves the transmission bandwidth requirement of encoded video for almost the same quality when compared to H.264/AVC, and the availability of increased network bandwidth (e.g. from 2 Mbps for 3G networks to almost 100 Mbps for 4G/LTE) have led to the proliferation of video streaming services. Based on these major innovations, the prevalence and diversity of video application are set to increase over the coming years. However, the popularity and success of current and future video applications will depend on the perceived quality of experience (QoE) of end users. How …

The Geometrical Thought Of Isaac Newton: An Examination Of The Meaning Of Geometry Between The 16th And 18th Centuries, Nicole Victoria Bloye

School of Engineering, Computing and Mathematics Theses

Our thesis explores aspects of the geometrical work and thought of Isaac Newton in order to better understand and re-evaluate his approach to geometry, and specifically his synthetic methods and the organic description of plane curves. In pursuing this research we study Newton's geometrical work in the context of the changing view of geometry between the late 16th and early 18th centuries, a period defined by the responses of the early modern geometers to a new Latin edition of Pappus' Collectio. By identifying some of the major challenges facing geometers of this period as they attempted to define and practice …

Normalizability, Integrability And Monodromy Maps Of Singularities In Three-Dimensional Vector Fields, Hussein Niazy

School of Engineering, Computing and Mathematics Theses

In this thesis we consider three-dimensional dynamical systems in the neighbourhood of a singular point with rank-one and rank-two resonant eigenvalues. We first introduce and generalize here a new technique extending previous work which was described by Aziz an Christopher (2012), where a second first integral of a 3D system can be found if the system has a Darboux-analytic first integral and an inverse Jacobi multiplier. We use this new technique to find two independent first integrals one of which contains logarithmic terms, allowing for non-zero resonant terms in the formal normal form of vector field. We also consider sufficient …

Detection Of Dns Based Covert Channels, Stephen Sheridan, Anthony Keane

Conference Papers

Information theft or data exfiltration, whether personal or corporate, is now a lucrative mainstay of cybercrime activity. Recent security reports have suggested that while information, such as credit card data is still a prime target, other data such as corporate secrets, employee files and intellectual property are increasingly sought after on the black market. Malicious actors that are intent on exfiltrating valuable data, usually employ some form of Advanced Persistent Threat (APT) in order to exfiltrate large amounts of data over a long period of time with a high degree of covertness. Botnets are prime examples of APTs that are …

Recruitment And Selection Strategies In Optometric Education Towards Addressing Human Resource Disparities In Sub-Saharan Africa, Vanessa Moodley, James Loughman, Kovin S. Naidoo

Articles

The dire need for eye care services and a dearth of human resources (HR) in sub-Saharan Africa motivated the setting up of new optometry programmes. However, to make a meaningful impact, geographical, gender, economic and educational disparities must additionally be addressed. A qualitative study utilizing purposive sampling to select academic leadership and students from optometry programmes in sub-Saharan Africa was conducted. Individual and focus group interviews produced data that were coded and analysed using a deductive thematic analysis approach. The themes that emerged as contributing to disparities in access through recruitment and selection were institutional barriers (student intake numbers, programme …

Dual Targeted Immunotherapy Via In Vivo Delivery Of Bio-Hybrid Rnai-Peptide Nanoparticles To Tumour-Associated Macrophages And Cancer Cells, Joao Conde, Chenchen Bao, Yeqi Tan, Daxiang Cui, Elazier Edelman, Helena Azevedo, Hugh Byrne, Natalie Artzi, Furong Tian

Articles

Lung cancer is associated with very poor prognosis and considered one of the leading causes of death worldwide. Here, we present highly potent and selective bio-hybrid RNAi-peptide nanoparticles that can induce specific and long-lasting gene therapy in inflammatory tumour associated macrophages (TAMs), via an immune modulation of the tumour milieu combined with tumour suppressor effects. Our data prove that passive gene silencing can be achieved in cancer cells using regular RNAi NPs. When combined with M2 peptide-based targeted immunotherapy that immuno-modulates TAMs cell-population, a synergistic effect and long-lived tumour eradication can be observed along with increased mice survival. Treatment with …

An Exploration Of The Effects On Programme Design And Development Effected By Educational Leadership In Reaction To Societal And Economic Factors In Ireland, Roisin Donnelly, Nuala Harding

Journal Articles

It has affected many countries around the world, and Irish higher education has not found itself immune from undergoing a period of significant change, powered by a number of factors: economic, political, and technological. While these trends are global in their scope, and profound in their impact, the pace of change in the Irish economy since 2007-08 in particular has required institutions and their educational leaders to encourage the emergence of programmes which can respond to the current national needs. In periods of rapid change such as this, educational leaders by necessity tend to focus on short-term strategy and transition …

An Intrinsic Case Study Into The Appropriateness Of A Bespoke Training Model As An Approach To Supporting The Postgraduate Demonstrator In Developing Pedagogical Skills Suitable For Undergraduate Scientific Laboratories., Barry Ryan

Theses

Postgraduate demonstrators (PGDs) are crucial to the smooth running of undergraduate teaching laboratories; however, they are oftentimes exiled to superficial duties such as enforcing health and safety and procedural instruction. The aim of this intrinsic case study was to characterise the support required by postgraduate demonstrators (PGDs) to develop the key pedagogical skills that would assist them in effectively demonstrating undergraduate science teaching labs. Through supporting PGD development, it is hoped to centralise the PGD in the undergraduate teaching lab and set in place the foundations for a move towards undergraduate teaching labs that encompass aspects of tailored research in …

Participatory Action Research: Effect Of Emphasising Graduate Attributes On Work-Placement Reflection, Julie Dunne

Theses

This project aimed to investigate what the effect of activities to promote awareness of graduate attributes development introduced during 2014/15 would be on the quality of reflection displayed in student pharmacy technicians’ workplacement blogs. The project was undertaken in response to a deficit in critical reflection shown in earlier years. The work-placement blogs from 2013/14 were used as a comparison for this study. The theoretical perspective included a constructivist ontological position and an interpretivist epistemological position. The methodology was participatory action research involving the Pharmacy Technician students as co-researchers. The cycles of action and research aligned to three research objectives, …

The Contribution Of Non-Thermal And Advanced Oxidation Technologies Towards Dissipation Of Pesticide Residues, N. Misra

Articles

Background

The use of pesticides has stabilised the food production to a great extent and their usage cannot be avoided anymore. Nevertheless, common food processing operations always allowed dissipating pesticide residues in foods to some extent. Within the food science community and the food processing sector, non-thermal food technologies are being researched and commercialised at a great pace over the past three decades.

Scope and Approach

In this review we provide a critical analysis of the literature pertinent to the fate of pesticide residues during non-thermal processing of solid and liquid foods. We also identify the opportunities for further development …

Computational Development Of Selective Nnos Inhibitors: Binding Modes And Pharmacokinetic Considerations, Adam Curtin, Gemma K. Kinsella, John Stephens

Articles

Abstract: Neuronal nitric oxide synthase (nNOS) produces the key signalling mediator nitric oxide, (NO). This gaseous, free radical molecule modulates a vast array of biological processes, from vascular pressure to immune responses and neurological signalling cascades. Overproduction of NO has been implicated in conditions including Alzheimer’s disease, Parkinson’s disease and schizophrenia. Inhibition of nNOS therefore offers a potential therapeutic approach for treatment of these conditions. This endeavour is made more complex by the fact that there are two other isoforms of nitric oxide synthase (NOS), endothelial NOS (eNOS) and inducible NOS (iNOS). The selectivity of nNOS inhibitors is therefore a …

A Mathematical Model Of Meat Cooking Based On Polymer-Solvent Analogy, M. Chapwanya, Nissreen Misra

Articles

Mathematical modelling of transport phenomena in food processes is vital to understand the process dynamics. In this work, we study the process of double sided cooking of meat by developing a mathematical model for the simultaneous heat and mass transfer. The constitutive equations for the heat and mass transport are based on Fourier conduction, and the Flory–Huggins theory respectively, formulated for a two-phase transport inside a porous medium. We investigate a reduced one-dimensional case to verify the model, by applying appropriate boundary conditions. The results of the simulation agree well with experimental findings reported in literature. Finally, we comment upon …

On The Dynamics Of Internal Waves Interacting With The Equatorial Undercurrent, Alan Compelli, Rossen Ivanov

Articles

The interaction of the nonlinear internal waves with a nonuniform current with a specific form, characteristic for the equatorial undercurrent, is studied. The current has no vorticity in the layer, where the internal wave motion takes place. We show that the nonzero vorticity that might be occuring in other layers of the current does not affect the wave motion. The equations of motion are formulated as a Hamiltonian system.

Hamiltonian Approach To Internal Wave-Current Interactions In A Two-Media Fluid With A Rigid Lid, Alan Compelli, Rossen Ivanov

Articles

We examine a two-media 2-dimensional fluid system consisting of a lower medium bounded underneath by a flatbed and an upper medium with a free surface with wind generated surface waves but considered bounded above by a lid by an assumption that surface waves have negligible amplitude. An internal wave driven by gravity which propagates in the positive x-direction acts as a free common interface between the media. The current is such that it is zero at the flatbed but a negative constant, due to an assumption that surface winds blow in the negative x-direction, at the lid. We are concerned …
