A Comparative Study Of The Effect Of Sensor Noise On Activity Recognition Models, Robert J. Ross, John D. Kelleher

Conference papers

To provide a better understanding of the relative strengths of Machine Learning based Activity Recognition methods, in this paper we present a comparative analysis of the robustness of three popular methods with respect to sensor noise. Specifically we evaluate the robustness of Naive Bayes classifier, Support Vector Machine, and Random Forest based activity recognition models in three cases which span sensor errors from dead to poorly calibrated sensors. Test data is partially synthesized from a recently annotated activity recognition corpus which includes both interleaved activities and a range of both temporally long and short activities. Results demonstrate that the relative …

An Investigation Of The Biochemical Properties Of Tetrazines As Potential Coating Additives, Swarna Jaiswal, Brendan Duffy, Luke O'Neill, Patrick Mchale

Articles

1,2,4,5-Tetrazine and its 3,6-disubstituted derivatives are currently used for a range of industrial and medical applications as they exhibit particular coordination chemistries, characterized by electron and charge transfer phenomena. The aim of the present work is to describe the synthesis of two tetrazine derivatives, namely 3,6-dihydrazino-1,2,4,5-tetrazine (DHDTZ) and 1,2,4,5-tetrazine dicarboxylic acid (DCTZ), and determine their antibacterial, antioxidant and anticorrosion characteristics as additives in a sol-gel coating on SS316L steel. The structure of the tetrazines was confirmed by NMR and FTIR while the surface morphology of bacterial cells in their presence was observed by AFM. Their ability to inhibit corrosion on …

Novel Microwave Assisted Synthesis Of Zns Nanomaterials, Suresh Pillai, Michael Seery, Damian Synnott, John Colreavy, Stephen Hinder

Articles

A novel ambient pressure microwave-assisted technique is developed in which silver and indium modified ZnS is synthesised. The as prepared ZnS is characterised by X-ray diffraction, UV-Vis spectroscopy, X-ray photoelectron spectroscopy and luminescence spectroscopy. This procedure produced crystalline materials with particle sizes below 10 nm. The synthesis technique leads to defects in the crystal which induce mid energy levels in the band gap and lead to indoor light photocatalytic activity. Increasing the amount of silver causes a phase transition from cubic blende to hexagonal phase ZnS. In a comparative study, when the ZnS cubic blende is heated in a conventional …

Expedited Approval Of Energy Projects: Toward Assessing The Forms Of Procedural Relief, Michael B. Gerrard

San Diego Journal of Climate & Energy Law

This research is heading toward two further sets of questions, which may or may not be reached in the current phase of the work.

First, if certain permits or reviews can be dispensed with for certain projects, and there are few negative collateral consequences, do we need these permits and reviews at all? Every proposed project is important to someone, and arguments can almost always be mounted that a given kind of project warrants special treatment. The present inquiry may help identify some requirements that are obsolete and should not apply to anyone, and it may also help identify others …

The Emergence Of Natural Gas And The Need For Cooperative Federalism To Address A Big "Fracking" Problem., Joshua P. Dennis

San Diego Journal of Climate & Energy Law

This Comment explores the recent emergence of natural gas production, the hydraulic fracturing process and briefly touches on the current regulatory system that oversees its operation. I then explain why the current regulatory system is insufficient to protect individuals and the environment from hydraulic fracturing. And lastly, I argue that a form of cooperative federalism is the best approach to regulate hydraulic fracturing.

Legal, Technical, And Economic Challenges In Integrating Renewable Power Generation Into The Electricity Grid, Timothy P. Duane, Kiran H. Griffith

San Diego Journal of Climate & Energy Law

This Article addresses the legal, technical, and economic challenges of integrating high levels of renewable power generation into electrical grid system operation. Part II shows that the primary integration challenge is reducing the total costs of integration and allocating the costs of integration in a hybrid regulatory structure, which presents different institutional impediments than traditional cost-of-service ratemaking or rate-of-return regulation. We demonstrate that the primary impediment to improved integration is a failure to make the critical policy choice about how such costs will be allocated. Part III describes and analyzes the BPA-wind dispute in order to evaluate the adequacy of …

Strategic Project/ Canteen Ireland, Yvonne Feehan

Students Learning with Communities

CanTeen Ireland is an organisation set up to support, empower and develop young people who have or have had cancer between the ages of 12 and 25. Set up in May 1990, the nationwide support group provides members with a place where they can simply be young people, away from the day to day pressures that come with living with cancer in the hospital or at home. Having no dedicated wards in Irish hospitals for teenagers with cancer, CanTeen is an important resource for the country and steps up where the HSE falls down. CanTeen does not rely on the …

Exploring The Use Of Web 2.0 Tools To Support Knowledge Sharing Within The Non-Profit Sector, Christina Shannon

Students Learning with Communities

This project will investigate the challenges of knowledge sharing and communication in non-profit organizations with a high dependence on volunteers. Projects of this type typically rely heavily on the knowledge of the volunteers for success and while many projects have some mechanisms through which they communicate and share knowledge such as a web presence, typically the knowledge is disparate, highly tacit, embedded in the people involved. A scattered approach is typical with knowledge and information on several different forums managed by several different people with no obvious connection. There is unlikely to be a cohesive, coherent approach in place to …

Effect Of Inhomogeneous Deformation On Anisotropy Of Az31 Magnesium Sheet, Jidong Kang, David S. Wilkinson, Raja K. Mishra, Wei Yuan, Rajiv S. Mishra

Materials Science and Engineering Faculty Research & Creative Works

Inhomogeneous plastic deformation in AZ31 magnesium sheet has been studied during uniaxial tensile testing using digital image correlation and electron backscatter diffraction techniques. Large strain gradients develop on the sheet surface parallel and perpendicular to the loading direction while very little deformation occurs in the thickness direction. This lack of thinning leads to an abrupt fracture following the development of a premature but extensive diffuse neck but without any localized neck. The strain distribution on the sheet surface evolves nonlinearly with strain, impacting the measured plastic strain ratio, r-value. The results show that r-value should be measured at "points" rather …

Editor's Note by John Nelson and Dayna Barnes

Languages of Human Rights in Timor-Leste by David Webster

This paper examines the historical process by which Timorese embraced the language of human rights, and their transnational support networks as diffusion belts for “rights talk.” It argues for a two-way understanding of rights diffusion, suggesting that Timorese framing of rights have contributed to a global shift towards a wider understanding of human rights as more than simply civil liberties in the Western tradition. Human rights, in other words, is a language that has served the Timorese independence cause, and in turn …

Nutritional Intervention Restores Muscle But Not Kidney Phenotypes In Adult Calcineurin Aα Null Mice, K. Madsen, R. N. Reddy, S. R. Price, C. R. Williams, Jennifer L. Gooch

PCOM Scholarly Works

Mice lacking the α isoform of the catalytic subunit of calcineurin (CnAα) were first reported in 1996 and have been an important model to understand the role of calcineurin in the brain, immune system, bones, muscle, and kidney. Research using the mice has been limited, however, by failure to thrive and early lethality of most null pups. Work in our laboratory led to the rescue of CnAα-/- mice by supplemental feeding to compensate for a defect in salivary enzyme secretion. The data revealed that, without intervention, knockout mice suffer from severe caloric restriction. Since nutritional deprivation is known to significantly …

Collaborating To Nowhere: The Imperative Of Government Accountability For Restoring The Chesapeake Bay, Rena I. Steinzor, Shana Jones

Faculty Scholarship

This Article opens with an analysis of why the Chesapeake Bay Program will repeat its past failures unless a reliable mechanism for ensuring accountability is created. It then explains how the independent evaluator should be constructed to make possible the overall success of Bay restoration. Finally, it closes with a rebuttal of the arguments in favor of self--auditing and against independent review.

Fighting Cybercrime After United States V. Jones, David C. Gray, Danielle Keats Citron, Liz Clark Rinehart

Faculty Scholarship

In a landmark non-decision last term, five Justices of the United States Supreme Court would have held that citizens possess a Fourth Amendment right to expect that certain quantities of information about them will remain private, even if they have no such expectations with respect to any of the information or data constituting that whole. This quantitative approach to evaluating and protecting Fourth Amendment rights is certainly novel and raises serious conceptual, doctrinal, and practical challenges. In other works, we have met these challenges by engaging in a careful analysis of this “mosaic theory” and by proposing that courts focus …

Licensed To Care: Inhabiting The Transnational Economy Of "Global Pinoy", Fidel Taguinod

Doctoral

The Philippines’ experience in international labour migration is widely considered a success – an observation endorsed by international bodies such as the World Health Organisation. As an active source of professional nurses to the developed world, the country continues to produce more nurses than the local nursing market can employ; a labour strategy that is promoted, facilitated and supported by the Philippine state and nursing educational system. This thesis interrogates Filipino nurse migration through the methodological prism of autoethnography, drawing on first-hand experience and reflexive accounts, interviews, photographs, policy documents and material cultural artefacts, to critically examine and challenge the …

The Lismullin Enclosure:A Designed Ritual Space, Frank Prendergast

Book/Book Chapter

The discovery in 2007 of a prehistoric post-built enclosure at Lismullin, Co. Meath, during archaeological investigations in advance of the construction of the M3 motorway is, arguably, the most significant Irish archaeological discovery of recent times. This appendix summarises a commissioned specialist report on the spatial and archaeoastronomical features of the enclosure.

The Riai Standard Form Of Contract 2012 Edition: A Review, Tony Cunningham

Other Resources

The RIAI ‘yellow’ and ‘blue’ Forms of Contracts have been recently amended and published as the 2012 edition. The yellow form where quantities form part of the contract is identical to the 2011 edition and has been republished as the 2012 edition. The 2011 version superseded the 2002 version. This paper reviews and synopsises the provisions of the 2012 RIAI ‘yellow’ form of contract and identifies the principle changes to the 2002 edition.

Forget The FlâNeur, Conor Mcgarrigle

Articles

This paper discusses the connections between the ‘flâneur’, Baudelaire's symbol of modernity, the anonymous man on the streets of nineteenth century Paris, and his contemporary digital incarnation, the ‘cyberflâneur’. It is argued that, although the flâ- neur could be successfully re-imagined as the cyberflâneur in the early days of the web, this nine- teenth century model of male privilege no longer fits the purpose. It is suggested that it is time to forget the flâneur and search for a new model to consider the peripatetic nature of location-aware networked devices in the digitally augmented city.

Detection Of Thermoluminescence In Polyether Ether Ketone (Peek), Dipendra Adhikari

Electronic Theses and Dissertations Archive

Sterilization is a mandatory process for materials used in medical applications. Sterilization procedures commonly used are steam sterilization, ethylene oxide (EtO) sterilization and sterilization by radiation. The high energy photons incident upon a polymer can cause chain scission, crosslinking, defects (trapped electrons) within the polymer matrix, and the formation of free radicals. In this research work, we used thermally stimulated luminescence (TSL) and differential scanning calorimeter (DSC) to study the effects of X- and UV-irradiation on different grades of PEEK. We have observed a major sharp glow peak at temperature of about 150°C (with other five minor peaks), at the …

Using Modelling And Simulation To Improve Elderly Care In Ireland: A Case Study, Mohamed Ragab, Wael Rashwan, Waleed Abo-Hamad, Amr Arisha

Articles

Health care services both globally and domestically - are encountering critical issues due to the increasing demand for services at the time of economic recession. Hospital performance is subject to many constraints, and planning is made more difficult by the complexity and uncertainty of demand. Population ageing is creating immense pressures on healthcare facilities across the world, leaving them struggling to cope with the growing demand for elderly healthcare services. Current demand-supply gaps result in prolonged waiting times for patients and substantial cost burdens for healthcare systems due to delayed discharges. This paper reports on a project that uses modelling …

Pcv: Predicting Contact Volume For Reliable And Efficient Data Transfers In Opportunistic Networks, Shiraz Qayyum, Mehrab Shahriar, Mohan Kumar, Sajal K. Das

Computer Science Faculty Research & Creative Works

Exploiting opportunistic contacts between mobile devices to enable deployment of real applications through reliable and efficient data transfers poses a significant research challenge. Indeed, accurate prediction of contact volume, defined as the maximum amount of data transferable during a contact, can improve performance of deployments. However, existing schemes for estimating contact volume that make use of preconceived patterns or contact time distributions may not be applicable in uncertain environments. In this paper, we propose a novel scheme called PCV that predicts contact volume in soft real-time to enable efficient and reliable data transfers in opportunistic networks. An Android Application that …

New Yellow Ba0.93Eu0.07Al2O4, Xufan Li, John D. Budai, Feng Liu, Jane Y. Howe, Jiahua Zhang, Xiao-Jun Wang, Zhanjun Gu, Chengjun Sun, Richard S. Meltzer, Zhengwei Pan

Physics & Astronomy: Faculty Publications

Phosphor-converted white light-emitting diodes for indoor illumination need to be warm-white (i.e., correlated color temperature K) with good color rendition (i.e., color rendering index >80). However, no single-phosphor, single-emitting-center-converted white light-emitting diodes can simultaneously satisfy the color temperature and rendition requirements due to the lack of sufficient red spectral component in the phosphors’ emission spectrum. Here, we report a new yellow Ba_0.93Eu_0.07Al₂O₄phosphor that has a new orthorhombic lattice structure and exhibits a broad yellow photoluminescence band with sufficient red spectral component. Warm-white emissions with correlated color temperature 80 were readily achieved when …

Visuomotor Learning Enhanced By Augmenting Instantaneous Trajectory Error Feedback During Reaching, James L. Patton, John Wei Yejun, Preeti Bajaj, Robert A. Scheidt

Biomedical Engineering Faculty Research and Publications

We studied reach adaptation to a 30u visuomotor rotation to determine whether augmented error feedback can promote faster and more complete motor learning. Four groups of healthy adults reached with their unseen arm to visual targets surrounding a central starting point. A manipulandum tracked hand motion and projected a cursor onto a display immediately above the horizontal plane of movement. For one group, deviations from the ideal movement were amplified with a gain of 2 whereas another group experienced a gain of 3.1. The third group experienced an offset equal to the average error seen in the initial perturbations, while …

Scholarly Teaching: Suggestions For A Road More Traveled, Todd D. Zakrajsek

International Journal for the Scholarship of Teaching & Learning

Excerpt: Most academic disciplines throughout the world have been in the higher education curriculum for hundreds, and in some cases thousands, of years. Teaching itself has certainly been around as long as the earliest of any given discipline. After all, without teaching no profession is possible. How else would a core set of knowledge be taught to those interested in the theoretical constructs, conceptual frameworks, and the successes/failures of those who have worked previously in the discipline? Unfortunately, the concept of consistently teaching from a base of scholarly activity is relatively new. What happens, then, when the very concept …
