On The Advantages Of E100 Over Gasoline In Down-Sized, Turbo-Charged, Direct-Injected, Variable Valve Actuated, And Stoichiometric S.I. Engines, Alberto A. Boretti

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Current flexi fuel gasoline and ethanol engines have efficiencies generally lower than dedicated gasoline engines. Considering ethanol has a few advantages with reference to gasoline, namely the higher-octane number and the larger heat of vaporization, the paper explores the potentials of dedicated pure ethanol engines using the most advanced techniques available for gasoline engines, specifically direct injection, turbo charging and variable valve actuation. Computations are performed with state-of-the-art, well validated, engine and vehicle performance simulations packages, generally accepted to produce accurate results targeting major trends in engine developments. the higher compression ratio and the higher boost permitted by ethanol allows …

Use Of Bio-Ethanol And Bio-Diesel The Key Solution For A More Sustainable Road Transport, Alberto Boretti

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Life Cycle Analysis (LCA) of alternative transportation fuels clearly shows the advantages of reducing the use of nonrenewable fossil fuels vs. renewable biologic novel fuels to reduce the emissions of carbon dioxide. Being based on the natural recycle of carbon dioxide through the use of renewable energy sources, use of these renewable fuels does not imply depletion of natural resources and is therefore sustainable in the long term. Renewable fuels and advanced internal combustion engines and powertrains are the technologies that in addition to be the most likely to produce benefits in term of carbon balance and fossil fuel saving, …

A Unified Model-Based Fault Diagnosis Scheme For Nonlinear Discrete-Time Systems With Additive And Multiplicative Faults, Hasan Ferdowsi, Sarangapani Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a novel model-Based fault diagnosis scheme is proposed for a class of uncertain nonlinear discrete-time systems which can be subjected to both additive and multiplicative faults. Faults are detected by using a novel (FD) observer consisting of two online approximators in discrete-time (OLAD) and a robust adaptive term. Upon detection, a fault diagnosis scheme is introduced to determine the fault type by monitoring the input residual generated via the first OLAD output. Then the appropriate OLAD is included in the observer while the other OLAD is switched off. Next, by using both the parameter update law of …

Study Of Turbulence-Radiation Interaction In Hypersonic Turbulent Boundary Layers, L. (Lian) Duan, A. M. Feldick, M. P. Martín, M. F. Modest, D. A. Levin

Mechanical and Aerospace Engineering Faculty Research & Creative Works

In the paper, we conduct direct numerical simulations (DNS) to investigate the effect of turbulence-radiation interaction (TRI) in hypersonic turbulent boundary layers, representative of the Orion crew exploration vehicle (CEV) at peak heating condition during reentry. The radiative transfer equation (RTE) is solved using the tangent slab approximation. 1 The RTE solver is line-by-line (LBL) accurate, making use of a developed efficient spectral database 2 for spectral modeling. A multi-group full-spectrum correlated-k-distribution (FSCK) method 3 is used to reduce the number of RTE evaluations while preserving LBL accuracy. A nondimensional governing parameter to measure the significance of TRI is proposed, …

Assessment Of Turbulence-Chemistry Interaction In Hypersonic Turbulent Boundary Layers, L. (Lian) Duan, M. P. Martín

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Studies of the turbulence-chemistry interaction are performed in hypersonic turbulent boundary layers using direct numerical simulation flow fields under typical hypersonic conditions representative of blunt-body and slender body hypersonic vehicles, with super catalytic and noncatalytic wall conditions in pure air. Nondimensional governing parameters, the interaction Damköhler number and the interaction relative heat release, are proposed to measure the influence of turbulence-chemistry interaction on flow composition and temperature. Both a priori and posteriori studies are performed to assess the effect of turbulence-chemistry interaction on chemical production rates and mean and turbulent flow characteristics. It is found that the governing parameters provide …

Neural Network-Based Optimal Control For Trajectory Tracking Of A Helicopter Uav, David Nodland, H. Zargarzadeh, S. Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

Helicopter unmanned aerial vehicles (UAVs) may be widely used for both military and civilian operations. Because these helicopters are underactuated nonlinear mechanical systems, high-performance controller design for them presents a challenge. This paper presents an optimal controller design for trajectory tracking of a helicopter UAV using a neural network (NN). the state-feedback control system utilizes the backstepping methodology, employing kinematic and dynamic controllers. the online approximator-Based dynamic controller learns the infinite-horizon Hamilton-Jacobi-Bellman (HJB) equation in continuous time and calculates the corresponding optimal control input to minimize the HJB equation forward-in-time. Optimal tracking is accomplished with a single NN utilized for …

Innovation And Price Competition In A Two-Sided Market, Mei Lin, Shaojin Li, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

We examine a platform's optimal two-sided pricing strategy while considering seller-side innovation decisions and price competition. We model the innovation race among sellers in both finite and infinite horizons. In the finite case, we analytically show that the platform's optimal seller-side access fee fully extracts the sellers' surplus, and that the optimal buyer-side access fee mitigates price competition among sellers. The platform's optimal strategy may be to charge or subsidize buyers depending on the degree of variation in the buyers' willingness to pay for quality; this optimal strategy induces full participation on both sides. Furthermore, a wider quality gap among …

Issues And Guidelines In Modeling Decomposition Of Minimum Participation In Entity-Relationship Diagrams, Cecil Eng Huang Chua, Veda C. Storey

Business and Information Technology Faculty Research & Creative Works

The entity-relationship model has long been employed for conceptual modeling of databases. Methodologies and heuristics have been developed, both for effective modeling and for translating entity-relationship models into relational models. One aspect of modeling that is often overlooked in design methodologies is the use of optional versus mandatory participation (i.e., minimum participation) on the development of relational databases. This tutorial complements existing instructional material on database design by analyzing the syntactic implications of minimum participation in binary, unary, and n-ary relationship sets and for the special case where the E-R diagram depicts a database where 3NF is not in BCNF. …

The Innocence Rights Of Sentenced Offenders, Mary Rogan

Articles

Civil orders which take effect after a person has been released from a sentence of imprisonment have become more common features of Irish law. Despite representing a major departure from the principle that when a person has served a sentence the state has no further „call‟ on that person, such orders have received limited attention. This article examines some of these new orders, in particular section 26 and section 26A of the Criminal Justice Act 2007. It argues that these orders should be of concern, suggesting that they are likely to act as barriers to reintegration of ex-prisoners, represent a …

Criminalizing Corporate Killing: The Irish Approach, Bruce Carolan

Articles

The debate on criminal corporate liability in the United States might benefit from a comparative perspective: How have other countries treated the criminal liability of corporate entities? This benefit might be enhanced by focusing on a country with a similar legal heritage to the United States—a country with a common law legal system inherited from the British. And, it would help if that country were concurrently examining the issue of criminal corporate liability. Interesting questions might include: What issues dominate the debate? How are issues of punishment, reparations, and rehabilitation handled? Is a legislative approach contemplated? The purpose of this …

How Journalism Became A Profession, Michael Foley

Books/Book chapters

Newspaper developed in Ireland as a political press, with each publication clearly identified with particular political groupings. However, for reasons of economics journalism itself developed a professional paradign, that stressed impartiality, so allowing journalists to move from publication to publication regardless of the politics or religion of the journalist. Newspapers and journalists also helped develop a civil society that contributed to the eventual democratic nature of the Irish state, following independence.

Journalism Educations And Child Rights: Exploring A New Model Of Collaboration In Rights-Based Journalism Education, Brian O'Neill, Michael Foley, Noirin Hayes

Conference Papers

This paper presents an overview and discussion of a unique approach to journalism education in the Central, East European and CIS region. In 2008, a group of universities initially in Turkey, and later joined by Romania, Georgia, Macedonia, Serbia, Azerbaijan and Kyrgyzstan joined with UNICEF to introduce a new child rights syllabus into their respective journalism programmes. For years, the approach to training journalists in children’s rights in the CEE/CIS region had been quantitative – 30 journalists here, 30 there. This has produced limited results in terms of the representation of children or children’s issues in the media. From point …

Cultural Perspectives On Globalisation And Ireland, Eamon Maher

Books

In the space of a few short decades, Ireland has become one of the most globalised societies in the Western world. The full ramifications of this transformation for traditional Irish communities, religious practice, economic activity, as well as literature and the arts, are as yet unknown. What is known is that Ireland’s largely unthinking embrace of globalisation has at times had negative consequences. Unlike some other European countries, Ireland has eagerly and sometimes recklessly grasped the opportunities for material advancement afforded by the global project.

This collection of essays, largely the fruit of two workshops organised under the auspices of …

What Critical Success Factors Are Necessary And Sufficient For Provision Of Development Care For Each Young Person In Irish Residential Care And Youth Care?, Gay Graham

Doctoral

This study seeks to better understand the organisational factors that impact on provision of
frontline residential care in Ireland. An historical overview of Irish residential youth care clarifies factors which shaped it by contriving to establish a system of residential youth care which catered for large numbers of children in institutions run by Catholic religious orders. A social risk model of care prevailed in Ireland, focused on the segregation and control of children by enforcement of a regimented, sectarian regime. Despite the fact that the Irish
Child Care Act 1991 which currently regulates residential child and youth care mandates

The Discursive Construction Of Irish Early Childhood Education And Care Policy: A Critical Discourse Analysis, Rachel Kiersey

Doctoral

Conceptual distinctions between care and early childhood education have influenced and reinforced the construction of knowledge about the early childhood education and care (ECEC) policy area. Discursive constructions in policy texts permeate wider society and become embodied in the broad social domain as “truths”, establishing the status quo about how social issues are perceived. Close scrutiny of the knowledge constructed about key concepts within Irish ECEC policy texts between 1998 and 2008 can shed some light on the ideological perspectives shaping the truths about ECEC in Irish society. This research used a critical discourse analysis (CDA) methodology to investigate policy …

A Globalised Vulnerability: Re-Presenting The Labouring Body Of Ireland's Newly Industrialised Landscape, Mark Curran

Doctoral

Situated in the context of globalisation in the Republic of Ireland, this ethnographically informed practice-based thesis addresses the critical relationship between visual arts practice, curatorship, the historical representation of labour, industrialised space and contemporary global labour practices. Drawing on audio and visual ethnographic material generated in my fieldsite - the Hewlett-Packard Manufacturing and Research complex in Leixlip, Ireland, together with the resulting installation and publication titled The Breathing Factory, it further investigates the dissemination of such epistemologies, the term ‘re-representation' being deployed as a reflexive gesture in acknowledgement of such critical re-contextualisations.

Ultra-Abrupt Tapered Fiber Mach-Zehnder Interferometer Sensors, B. Li, J. Lan, W. Sumei, L. Zhou, Hai Xiao, Hai-Lung Tsai

Electrical and Computer Engineering Faculty Research & Creative Works

A fiber inline Mach-Zehnder interferometer (MZI) consisting of ultra-abrupt fiber tapers was fabricated through a new fusion-splicing method. By fusion-splicing, the taper diameter-length ratio is around 1:1, which is much greater than those (1:10) made by stretching. The proposed fabrication method is very low cost, 1/20-1/50 of those of LPFG pair MZI sensors. The fabricated MZIs are applied to measure refractive index, temperature and rotation angle changes. The temperature sensitivity of the MZI at a length of 30 mm is 0.061 nm/°C from 30-350 °C. The proposed MZI is also used to measure rotation angles ranging from 0° to 0.55°; …

High-Strength Selfconsolidating Concrete Girders Subjected To Elevated Compressive Fiber Stresses, Part 2: Structural Behavior, Jared E. Brewe, John J. Myers

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The design of prestressed concrete members is restricted by the requirement that the extreme compressive fiber stress at midspan be less than 60% of the concrete compressive strength at release of prestressing. the purported purpose of this limit is to provide serviceability performance, but it places unnecessary limits on the capability of the materials. for this research program, six prestressed concrete girders were produced with high-strength, self-consolidating concrete and subjected to elevated compressive fiber stress levels ranging from 65% to 84% of initial concrete compressive strength at release of prestressing. Part 1 of this series analyzed time-dependent prestress losses and …

Reaction Rates Of Ozone And Terpenes Adsorbed To Model Indoor Surfaces, M. Springs, J. R. Wells, Glenn Morrison

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Reaction rates and reaction probabilities have been quantified on model indoor surfaces for the reaction of ozone with two monoterpenes (Δ3-carene and d-limonene). Molar surface loadings were obtained by performing breakthrough experiments in a plug-flow reactor (PFR) packed with beads of glass, polyvinylchloride or zirconium silicate. Reaction rates and probabilities were determined by equilibrating the PFR with both the terpene and the ozone and measuring the ozone consumption rate. to mimic typical indoor conditions, temperatures of 20, 25, and 30°C were used in both types of experiments along with a relative humidity ranging from 10% to 80%. the molar surface …
