Hamiltonian Approach to the Modeling of Internal Geophysical Waves with Vorticity

Alan Compelli
We examine a simplified model of internal geophysical waves in a rotational 2-dimensional water-wave system, under the influence of Coriolis forces and with gravitationally induced waves. The system consists of a lower medium, bound underneath by an impermeable flat bed, and an upper lid. The 2 media have a free common interface. Both media have constant density and constant (non-zero) vorticity. By examining the governing equations of the system we calculate the Hamiltonian of the...


Vladimir Gerdjikov
We are analyzing several types of dynamical systems which are both integrable and important for physical applications. The first type are the so-called peakon systems that appear in the singular solutions of the Camassa-Holm equation describing special types of water waves. The second type are Toda chain systems, that describe molecule interactions. Their complexifications model soliton interactions in the adiabatic approximation. We analyze the algebraic aspects of the Toda chains and describe their real Hamiltonian...

Dark Solitons of the Qiao's Hierarchy

Rossen Ivanov
We obtain a class of soliton solutions of the integrable hierarchy which has been put forward in a series of works by Z. Qiao. The soliton solutions are in the class of real functions approaching constant value fast enough at infinity, the so-called 'dark solitons'.

3D Growth Substrates in Mammalian Cell Culture in Vitro, their Effects on Cellular Function and Response

Mahmoud Gargotti
Three-dimensional (3D) cell culture systems have gained increasing interest in drug discovery and tissue engineering due to a number of advantages in providing more physiologically relevant information and potentially more predictive data for in vivo tests. Extracellular matrix (ECM) proteins have been developed over in recent years to simulate a natural microenvironment for cells cultured in vitro. Conventional cell culture or 2D cell culture form monolayers of cells on a solid surface, which is typically...

Multivariate Statistical Methodologies used in In-vitro Raman Spectroscopy: Simulations and Applications for Drug and Nanoparticle Interactions

Mark Edward Keating
Raman spectroscopy is a growing technology in the fields of in-vitro drug and nanoparticle screening. The label free capability provided by vibrational spectroscopy, as well as the ability of the technique to probe the chemical nature of samples, makes it a good candidate for use in these fields. Crucial to the progress of these methods is the development and validation of robust and accurate multivariate statistical analysis protocols. In this thesis, both established and novel...

Essays in Energy Economics and Policy

Michael Chesser
The world is currently going through an ‘Energy Transition’ and it is changing how our economies, culture and society operate. The research presented in this thesis emanates from large scale changes and is investigated through three distinct research papers, with separate but interlinked themes. Research paper 1 (Chapter 2) profiles households that have adopted of micro renewable energy systems (micro-RES) and examines whether micro-RES installations have impacted energy consumption based on data from the Irish...

Mechanisms Driving Digital New Venture Creation & Performance: An Insider Action Research Study of Pure Digital Entrepreneurship in EdTech

Kisito Futonge Nzembayie
Digitisation has ushered in a new era of value creation where cross border data flows generate more economic value than traditional flows of goods. The powerful new combination of digital and traditional forms of innovation has seen several new industries branded with a ‘tech’ suffix. In the education technology sector (EdTech), which is the industry context of this research, digitisation is driving double-digit growth into a projected $240 billion industry by 2021.

An Examination of the Smote and Other Smote-based Techniques That Use Synthetic Data to Oversample the Minority Class in the Context of Credit-Card Fraud Classification

Eduardo Parkinson de Castro
This research project seeks to investigate some of the different sampling techniques that generate and use synthetic data to oversample the minority class as a means of handling the imbalanced distribution between non-fraudulent (majority class) and fraudulent (minority class) classes in a credit-card fraud dataset. The purpose of the research project is to assess the effectiveness of these techniques in the context of fraud detection which is a highly imbalanced and cost-sensitive dataset. Machine learning...

Unfortunately, the email overload outbreak has developed into a personal trouble for users as well as a financial concerns for businesses. Accessing an ever-increasing number of lengthy emails in the present generation has become a major concern for many users. Email text summarization is a...

Optimal control strategy of UPQC for minimum operational losses

Malabika Basu, Michael Farrell, Michael Conlon, Kevin Gaughan & Eugene Coyle
The paper deals with a new control technique for a unified power quality conditioner (UPQC), which is the most comprehensive of FACTS devices. The problems of power quality continue to gain in significance because of the proliferation of sensitive and harmonic producing loads in electrical networks. Greater awareness among customers with regard to supply integrity and a desire by suppliers to be able to guarantee a certain degree of power quality to customers is being...

Environment Department Doesn’t Have a Clue on Housing

Lorcan Sirr
Over the past two years Sherlock Holmes’s evil foe Professor Moriarty has been wandering the corridors of the Department of the Environment, Community and Local Government, wreaking sublime havoc and leaving several reputation-damaging debacles in his wake. The damage has been so bad that in late 2014 an internal review was carried out. Released to RTE under freedom of information laws, the report was critical of the housing capabilities and activities of the department. Given...

Help-to-buy Scheme is Detached From How we Really Live

Lorcan Sirr
The government’s help-tobuy scheme, announced in the budget, was rightfully criticised by many people. Various ministers seemed a little surprised, if not a bit tetchy, that fewpeople had rowed in behind their latest genius wheeze. In research carried out by Davy stockbrokers and the property website myhome.ie, even firsttime buyers did not expect a helpto- buy scheme (people are not too easily schmoozed these days). Two other things flew under the radar when the proposal...

Our Reliance on Family for Housing Support Won’t last Forever

Lorcan Sirr
History is more important than geography in explaining our relationship with housing. We have a funny relationship with housing in Ireland, one that goes beyond the usual explanation of our land and property obsession being a post-colonial hang-up. Given our location at the northwest edge of Europe, it would be logical to assume Ireland would have a similar approach to housing as Germany, France and the Netherlands. We are different from our regional neighbours, however,...

To Solve Housing Crisis, we Must get over our Problem With Cities

Lorcan Sirr
Housing is a many-headed beast with elements of technology, planning, finance, sociology and of course, politics. At its core, however, it is a simple thing: buildings for people and this is why it’s crucial to keep an eye on our population statistics. Preliminary results fromthe recent census are throwing up some interesting figures, all of which have implications for where we should be focusing our efforts to build housing. The location of our empty houses...

No Landlord Exodus but Still the Same old Eviction Problems

Lorcan Sirr
There has been a lot of discussion this year about concerns that landlords are fleeing the rental market in the face of rent freezes and difficulties in making a profit — but are they? First, it is important to note that it is not the number of landlords in a market that is relevant, it’s the number of tenancies, which is a measure of the size of the sector. The sector has actually expanded in...

The Future Looks Precarious for New Breed of Long-Term Renters

Lorcan Sirr
It is becoming increasingly evident across Europe and Ireland that there may be a generation of people who will never own their own home. This is not necessarily down to direct housing issues such as affordability or supply—there are broader forces at work here. These people have no predictability in their lives and no security. They are a large and growing social class. Yet they are relatively powerless and are at the mercy of forces...
