Effect Of Snr Of Input Signal On The Accuracy Of A Ratiometric Wavelength Measurement System, Ginu Rajan, Qian Wang, Gerald Farrell, Yuliya Semenova, Pengfei Wang May 2007

Effect Of Snr Of Input Signal On The Accuracy Of A Ratiometric Wavelength Measurement System, Ginu Rajan, Qian Wang, Gerald Farrell, Yuliya Semenova, Pengfei Wang

Articles

The impact of a change in SNR of the input signal on the accuracy of a ratiometric wavelength measurement system is studied. The variation of the output ratio of the system due to the change in SNR of the input signal is modeled and the experimental investigation has been carried out, and both indicate that the accuracy is influenced significantly by variations in the SNR of the input signal. The demonstration example shows a wavelength shift of 0.055 nm when the SNR of the input signal varies from 47 dB to 42 dB (the measurable range is from 1500 nm …


Using The Technology Of The Confessional As An Analytical Resource: Four Analytical Stances Towards Research Interviews In Discourse Analysis, Brendan O'Rourke, Martyn Pitt May 2007

Using The Technology Of The Confessional As An Analytical Resource: Four Analytical Stances Towards Research Interviews In Discourse Analysis, Brendan O'Rourke, Martyn Pitt

Articles

Among the various approaches that have developed from FOUCAULT's work is an Anglophone discourse analysis that has attempted to combine FOUCAULTian insights with the techniques of Conversation Analysis. An important current methodological issue in this discourse analytical approach is its theoretical preference for "naturally occurring" rather than research interview data. A FOUCAULTian perspective on the interview as a research instrument, questions the idea of "naturally-occurring discourse". The "technology of the confessional" operates, not only within research interviews, but permeates other interactions as well. Drawing on FOUCAULT does not dismiss the problems of the interview as research instrument rather it shows …


Performing Tourism In Venice: Local Residents In Focus, Bernadette Quinn Apr 2007

Performing Tourism In Venice: Local Residents In Focus, Bernadette Quinn

Articles

In contrast to the growing literature on tourist mobility as a performed art, relatively little attention has been paid to resident mobility in tourism places. This paper examines how residents encounter tourists using the concept of tourism as a performance. Drawing on the case of the historic city-center of Venice in northeastern Italy, it explores the spatialities produced through the embodied practices of local mobilities. The paper finds that their movements demonstrated a marked degree of agency. It concludes by arguing that the concept of tourism as performance affords useful insights into how local residents are proactively and intricately involved …


Polarization Dependence Of Bend Loss For A Standard Singlemode Fiber, Qian Wang, Ginu Rajan, Pengfei Wang, Gerald Farrell Apr 2007

Polarization Dependence Of Bend Loss For A Standard Singlemode Fiber, Qian Wang, Ginu Rajan, Pengfei Wang, Gerald Farrell

Articles

Polarization dependence of bend loss caused by the polymer coating layer for a standard singlemode fiber (SMF28) is investigated theoretically and experimentally. Bend loss for SMF28 for both the TE and TM mode is calculated separately. Normalized polarization dependent loss is proposed for the characterization of the polarization sensitivity of bend loss for different bend radii. Corresponding experimental tests are presented, which agree with the theoretical results. Both the theoretical and experimental results show that the polymer coating layer has a significant influence on the polarization dependence of bend loss.


A Three‐Dimensional Numerical Method For Modelling Weakly Ionized Plasmas, Stephen O'Sullivan, Turlough Downes Apr 2007

A Three‐Dimensional Numerical Method For Modelling Weakly Ionized Plasmas, Stephen O'Sullivan, Turlough Downes

Articles

Astrophysical fluids under the influence of magnetic fields are often subjected to single- or two-fluid approximations. In the case of weakly ionized plasmas, however, this can be inappropriate due to distinct responses from the multiple constituent species to both collisional and non-collisional forces. As a result, in dense molecular clouds and protostellar accretion discs, for instance, the conductivity of the plasma may be highly anisotropic leading to phenomena such as Hall and ambipolar diffusion strongly influencing the dynamics.


The Internationalization Of Lay Legal Decision-Making: Jury Resurgence And Jury Research, Richard O. Lempert Apr 2007

The Internationalization Of Lay Legal Decision-Making: Jury Resurgence And Jury Research, Richard O. Lempert

Articles

When I first began to study the jury more than thirty years ago, the topic of this Journal issue, jury systems around the world, was unthinkable. The use of juries, especially in civil litigation, had long been in decline, to the point of near extinction in England, the land of their birth, and the live question was whether the jury system would endure in the United States. It seemed clear that juries would not continue in their classic form, as many U.S. states, with the Supreme Court's eventual approval, mandated juries of less than twelve people and allowed verdicts to …


Essay: On The Divergent American Reactions To Terrorism And Climate Change, Cass R. Sunstein Mar 2007

Essay: On The Divergent American Reactions To Terrorism And Climate Change, Cass R. Sunstein

Articles

Two of the most important sources of catastrophic risk are terrorism and climate change. The United States has responded aggressively to the risk of terrorism while doing very little about the risk of climate change. For the United States alone, the cost of the Iraq War is in excess of the anticipated cost of the Kyoto Protocol. The divergence presents a puzzle; it also raises more general questions about both risk perception and the public demand for legislation. The best explanation for the divergence emphasizes bounded rationality. Americans believe that aggressive steps to reduce the risk of terrorism promise to …

On Your Mark, Get Set, Go! Overview Of A Digital Project From Start To Finish, Pam Hackbart-Dean, Doug Goans, Lauren Kata

Articles

Rome wasn't built in a day, nor was an online collection of 105 years' worth of association publications. But a team of Georgia librarians had the stamina for a marathon project that lasted 2 years. Members even built their own digital library system along the way, and so far, the finished site has logged more than 65,000 unique visits.

Articles

The ACS Virgo Cluster Survey consists of HST/ACS imaging for 100 early–type galaxies in the Virgo cluster, observed in the F475W(≈ SDSS g) and F850LP (≈ SDSS z) filters. We derive distances for 84 of these galaxies using the method of Surface Brightness Fluctuations (SBF), present the SBF distance catalog, and use this database to examine the three-dimensional distribution of early–type galaxies in the Virgo Cluster. The SBF distance moduli have a mean (random) measurement error of 0.07 mag (0.5 Mpc), or roughly three times better than previous SBF measurements for Virgo Cluster galaxies. Five galaxies lie at a distance …


Privacy Preserving Telecardiology Sensor Networks: Towards A Low-Cost Portable Wireless Hardware/Software Co-Design, Fei Hu, Meng Jiang, Mark Wagner Jan 2007

Privacy Preserving Telecardiology Sensor Networks: Towards A Low-Cost Portable Wireless Hardware/Software Co-Design, Fei Hu, Meng Jiang, Mark Wagner

Articles

Recently, a remote-sensing platform based on wireless interconnection of tiny ECG sensors called Telecardiology Sensor Networks (TSN) provided a promising approach to perform lowcost real-time cardiac patient monitoring at any time in community areas (such as elder nursing homes or hospitals). The contribution of this research is the design of a practical TSN hardware/software platform for a typical U.S. healthcare community scenario (such as large nursing homes with many elder patients) to perform realtime healthcare data collections. On the other hand, due to the radio broadcasting nature ofMANET, a TSN has the risk of losing the privacy of patients’ data. …


Improving Software Practice Through Education: Challenges And Future Trends, Jorge Diaz-Herrera, Richard Leblanc Jr., Timothy Lethbridge Jan 2007

Improving Software Practice Through Education: Challenges And Future Trends, Jorge Diaz-Herrera, Richard Leblanc Jr., Timothy Lethbridge

Articles

We argue that the software engineering (SE) community could have a significant impact on the future of the discipline by focusing its efforts on improving the education of software engineers. There are some bright spots such as the various projects to codify knowledge, and the development of undergraduate SE programs. However, there remain several key challenges, each of which is addressed in this paper: The challenges are 1) making programs attractive to students, 2) focusing education appropriately, 3) communicating industrial reality more effectively, 4) defining curricula that are forward-looking, 5) providing education for existing practitioners, 6) making SE education more …

Waging A Private War: Us Security Contractors In Iraq, Tom Clonan Jan 2007

Waging A Private War: Us Security Contractors In Iraq, Tom Clonan

Articles

Iraq’s Prime Minister, Nouri al-Maliki has repeatedly expressed grave misgivings about the activities of US ‘Private Military Company’ (PCM) Blackwater Security and has cited at least seven shooting incidents involving the company’s security contractors which have led to the deaths of dozens of Iraqi citizens. Headquartered in Moyock, North Carolina, Blackwater – which is under contract to the US State Department - is currently operating in Iraq without an Iraq Interior Ministry licence. This absence of Iraqi oversight is compounded by a 2004 Coalition Provisional Authority law signed by Paul Bremer which grants Blackwater immunity from prosecution under Iraqi law. …


The Need For A Speech Corpus, Dermot Campbell, Ciaran Mcdonnell, Marty Meinardi, Bunny Richardson Jan 2007

The Need For A Speech Corpus, Dermot Campbell, Ciaran Mcdonnell, Marty Meinardi, Bunny Richardson

Articles

This paper outlines the ongoing construction of a speech corpus for use by applied linguists and advanced EFL/ESL students. The first section establishes the need for improvements in the teaching of listening skills and pronunciation practice for EFL/ESL students. It argues for the need to use authentic native-to-native speech in the teaching/learning process so as to promote social inclusion and contextualises this within the literature, based mainly on the work of Swan, Brown and McCarthy. The second part addresses features of native speech flow which cause difficulties for EFL/ESL students (Brown, Cauldwell) and establishes the need for improvements in the …

This research investigated how access to an annual holiday can benefit children living in poverty and their families. It studied children who had the opportunity to avail of a child-centred, structured group holiday provided by three NGOs. Study participants were drawn from a cross-section of disadvantaged areas in Dublin, comprising two inner-city and four suburban areas. Data collection involved 75 children and 35 guardians in the first stage, and 27 children and 16 guardians in subsequent stages. In total, 16 families participated in all stages of the research process, which used qualitative methods, including focus groups, in-depth interviews and observation. …


An Optimized Macrobending Fiber Based Edge Filter, Pengfei Wang, Gerald Farrell, Qian Wang, Ginu Rajan Jan 2007

An Optimized Macrobending Fiber Based Edge Filter, Pengfei Wang, Gerald Farrell, Qian Wang, Ginu Rajan

Articles

An optimized all-fiber edge filter is developed, based on a one-turn macrobending bare fiber structure. The discrimination range (DR) is 16.32 dB over a wavelength range from 1500 to 1600 nm, which can be employed for wavelength measurement applications. It offers a simpler structure compared to the previously developed macrobending fiber loss edge filters, without an increase in the polarization dependent loss (PDL).

Modulation Of Radiation Responses By Pre-Exposure To Irradiated Cell Conditioned Medium, Paula Maguire, Carmel Mothersill, B. Mcclean, C. Seymour, Fiona Lyng Jan 2007

Modulation Of Radiation Responses By Pre-Exposure To Irradiated Cell Conditioned Medium, Paula Maguire, Carmel Mothersill, B. Mcclean, C. Seymour, Fiona Lyng

Articles

The aim of this study was to investigate whether exposure of HPV-G cells to irradiated cell conditioned medium (ICCM) could induce an adaptive response if the cells were subsequently challenged with a higher ICCM dose. Clonogenic survival and major steps in the cascade leading to apoptosis, such as calcium influx and loss of mitochondrial membrane potential, were examined to determine whether these events could be modified by giving a priming dose of ICCM before the challenge dose. Clonogenic survival data indicated an ICCMinduced adaptive response in HPV-G cells ‘‘primed’’ with 5 mGy or 0.5 Gy ICCM for 24 h and …


Spline Based Geometry For Printed Monopole Antennas, Matthias John, Max Ammann Jan 2007

Spline Based Geometry For Printed Monopole Antennas, Matthias John, Max Ammann

Articles

A novel Bezier spline-based geometry for printed monopole antennas is presented. Quadratic curves are used to describe the outline of the radiating element. The geometry is optimised by a genetic algorithm. A small number of control points are used to define the geometry, ensuring a small search space for the GA. The resulting antenna has an impedance bandwidth from 1.44 to 14.7 GHz
