Geometric Modeling Of Engineered Abrasive Processes, Andres L. Carrano, James B. Taylor

Articles

One of the common issues that arises in abrasive machining is the inconsistency of the surface roughness within the same batch and under identical machining conditions. Recent advances in engineered abrasives have allowed replacement of the random arrangement of minerals on conventional belts with precisely shaped structures uniformly cast directly onto a backing material. This allows for abrasive belts that are more deterministic in shape, size, distribution, orientation, and composition. A computer model based on known tooling geometry was developed to approximate the asymptotic surface profile that was achievable under specific loading conditions. Outputs included the theoretical surface parameters, R^sub …

Educational Interpreting: Access And Outcomes, Marc Marschark, Patricia Sapere, Carol Convertino, Rosemarie Seewagen

Articles

This chapter argues that the assumption that mainstream education—supported by sign language interpreting—can provide deaf students with fair and appropriate public education may be unfounded. It describes research that emphasizes the need to understand better the complex personal and functional interactions of students, instructors, interpreters, and settings if educational interpreting—and interpreted education— is to be optimally beneficial for deaf students.

Stressed Plastics By Polarization, Andrew Davidhazy

Articles

Many transparent objects, especially those made of plastic, although other materials behave similarly, change the character of an incident beam of light in a manner that is hardly visible to the naked eye. However, this property of can be used to produce some truly spectacular visual results.

Tax Law Uncertainty And The Role Of Tax Insurance, Kyle D. Logue

Articles

In the broadest sense, this is an article about legal or regulatory uncertainty and the role that private and public insurance can play in managing it. More narrowly, the article is about tax law enforcement and the familiar if ill-defined distinctions between tax evasion, tax avoidance, and abusive tax avoidance. Most specifically, the article is about a new type of tax risk insurance policy, sometimes called tax indemnity insurance or transactional tax risk insurance that provides coverage against the risk that the Internal Revenue Service (Service) will disallow a taxpayer-insured's tax treatment of a particular transaction. The question is whether …

An Explicit Mapping Between The Frequency Domain And The Time Domain Representations Of Nonlinear Systems, Marissa Condon, Rossen Ivanov

Articles

Explicit expressions are presented that describe the input-output behaviour of a nonlinear system in both the frequency and the time domain. The expressions are based on a set of coefficients that do not depend on the input to the system and are universal for a given system. The anharmonic oscillator is chosen as an example and is discussed for different choices of its physical parameters. It is shown that the typical approach for the determination of the Volterra Series representation is not valid for the important case when the nonlinear system exhibits oscillatory behaviour and the input has a pole …

Printed Triband Terminal Antenna, Matthias John, Max Ammann, Ronan Farrell

Articles

This paper presents a printed triple-band multibranch monopole for use in modern wireless systems. The antenna is designed to operate in three bands which cover virtually all wireless channels. Parameters of the antenna geometry are varied and the effects of these variations on the impedance bandwidth are shown.

Optimization Of Impedance Bandwidth For The Printed Rectangular Monopole Antenna, Matthias John, Max Ammann

Articles

This paper describes a printed rectangular-plate monopole fed by microstrip line. The effect of varying the plate width, feed-gap height, and feedline width on the impedance bandwidth is examined. It is shown that for a fixed ground-plane size, that optimization of these parameters can yield an impedance bandwidth ratio of 4.3:1, without using any broadbanding techniques.

Future Reasoning Machines: Mind And Body, Brian Duffy, Gregory O'Hare, John Bradley, Bianca Schoen-Phelan

Articles

In investing energy in developing reasoning machines of the future, one must abstract away from the specific solutions to specific problems and ask what are the fundamental research questions that should be addressed. This paper aims to revisit some fundamental perspectives and promote new approaches to reasoning machines and their associated form and function. Core aspects are discussed, namely the one-mind-many-bodies metaphor as introduced in the Agent Chameleon work. Within this metaphor the agent’s embodiment form may take many guises with the artificial mind or agent potentially exhibiting a nomadic existence opportunistically migrating between a myriad of instantiated embodiments. We …

Why Lawyers Are Unhappy, Martin E.P. Seligman, Paul R. Verkuil, Terry H. Kang

Articles

[According to the authors of this article, the growing unhappiness of lawyers, particularly young lawyers, stems from three causes: (1) Lawyers are selected for their pessimism (or "prudence") and this generalizes to the rest of their lives; (2) Young associates hold jobs that are characterized by high pressure and low decision latitude, exactly the conditions that promote poor health and poor morale; and (3) American law is to some extent a zero-sum game, and negative emotions flow from zero-sum games....

This article has been shared with practitioners as well as academics. It grows out of faculty seminars held at the …

Gene Therapy And Targeted Toxins For Glioma, James Curtin, Gwendalyn King, Marianela Candolfi, Kurt Kroeger, Pedro Lowenstein, Maria Castro

Articles

The most common primary brain tumor in adults is glioblastoma. These tumors are highly invasive and aggressive with a mean survival time of nine to twelve months from diagnosis to death. Current treatment modalities are unable to significantly prolong survival in patients diagnosed with glioblastoma. As such, glioma is an attractive target for developing novel therapeutic approaches utilizing gene therapy. This review will examine the available preclinical models for glioma including xenographs, syngeneic and genetic models. Several promising therapeutic targets are currently being pursued in pre-clinical investigations. These targets will be reviewed by mechanism of action, i.e., conditional cytotoxic, targeted …

Combining Cytotoxic And Immune-Mediated Gene Therapy To Treat Brain Tumors, James Curtin, Gwendalyn King, Marianela Candolfi, Remy Greeno, Kurt Kroeger, Pedro Lowenstein, Maria Castro

Articles

Glioblastoma (GBM) is a type of intracranial brain tumor, for which there is no cure. In spite of advances in surgery, chemotherapy and radiotherapy, patients die within a year of diagnosis. Therefore, there is a critical need to develop novel therapeutic approaches for this disease. Gene therapy, which is the use of genes or other nucleic acids as drugs, is a powerful new treatment strategy which can be developed to treat GBM. Several treatment modalities are amenable for gene therapy implementation, e.g. conditional cytotoxic approaches, targeted delivery of toxins into the tumor mass, immune stimulatory strategies, and these will all …

Real-Time Reverse Transcription Pcr For Detection And Quantitative Analysis Of Equine Influenza Virus, Michelle Quinlivan, Eugene Dempsey, Fergus Ryan, Sean Atkins, Ann Cullinane

Articles

Equine influenza is a cause of epizootic respiratory disease of the equine. The detection of equine influenza virus using real-time Light Cycler reverse transcription (RT)-PCR technology was evaluated over two influenza seasons with the analysis of 171 samples submitted for viral respiratory disease. Increased sensitivity was found in overall viral detection with this system compared to Directigen Flu A and virus isolation, which were 40% and 23%, respectively, that of the RT-PCR. The assay was also evaluated as a viable replacement for the more traditional methods of quantifying equine influenza virus, 50% egg infectious dose and 50% tissue culture infectious …

International Contracting Meets Information Technology: Tales From A Transpacific Seminar, Daniel H. Foote

Articles

The following account is in essence a personal memoir concerning the first year of what, at the time, was a novel course offering: an international negotiation simulation, conducted transnationally, in which teams of students from the University of Tokyo utilized e-mail, videoconference facilities, and other resources to negotiate a major acquisition agreement with teams of students from the University of Washington. I originally wrote the account in 2001. As of this writing, in early 2005, we have just completed the fifth year of the course; and in the interim, professors at a number of other universities have established courses along …

Intellectual Property Rights And Stem Cell Research: Who Owns The Medical Breakthroughs?, Sean M. O'Connor

Articles

This article will not address the science and ethics of stem cell research—at least as far as those topics are normally addressed in the existing literature. Instead, this article argues that an even more contentious battle is looming on the horizon, with dire practical consequences: Namely, who will own the revolutionary medical breakthroughs that are supposed to emerge from this research? Along the way, this article will assume that stem cell research will progress in some fashion and that at least some of the purported benefits will materialize.

But the central premise is that the pitch of the ownership battle …

Characterisation Of An Acrylamide-Based Photopolymer For Data Storage Utilizing Holographic Angular Multiplexing, Hosam Sherif, Izabela Naydenova, Suzanne Martin, Colm Mcginn, Vincent Toal

Articles

An acrylamide-based photopolymer formulated in the Centre for Industrial and Engineering Optics has been investigated with a view to further optimisation for holographic optical storage. Series of 18 to 30 gratings were angularly multiplexed in a volume of photopolymer layer at a spatial frequency of 1500 lines/mm. Since the photopolymer is a saturable material, an exposure scheduling method was used to exploit the entire dynamic range of the material and allow equal strength holographic gratings to be recorded. This investigation yielded the photopolymer M/# for moderately thin layers. Photopolymer temporal stability was also studied by measuring variations of material shrinkage, …

Holographic Patterning Of Acrylamide-Based Photopolymer Surface, Izabela Naydenova, Emilia Mihaylova, Suzanne Martin, Vincent Toal

Articles

The patterning of an acrylamide-based photopolymer surface by holographic recording is studied. The patterns are induced by light alone and no post-processing is required. Periodic surface modulation is observed in addition to a volume phase grating. An investigation has been carried out using white light interferometry into the dependence of the amplitude of the photo induced surface relief modulation on the spatial frequency, intensity of recording and sample thickness. The observed dependencies indicate that the diffusion of material during the holographic recording plays a major role in surface relief formation. The possibility for inscription of surface relief patterns opens the …

Modernization Of The Hilger And Watts Guage-Block Interferometer, Michael O'Hora, Brian Bowe, Vincent Toal, Sean Peyton

Articles

The Hilger & Watts gauge-block interferometer was designed and manufactured commercially in the 1950s. The instrument uses isotope lamps as wavelength standards to perform absolute length calibration of gauge blocks (slip gauges) up to 100 mm in length, to an accuracy of approximately 1 ppm. It is entirely manually operated. In order to make the instrument more suitable for the modern laboratory, new hardware has been added, and a customized software package developed to automate the measurement process. This paper shows how interferograms may be imaged successfully at each of the eight available wavelengths, and the critical fringe fraction measurement …

Optimum Design Of The Printed Strip Monopole, Max Ammann, Matthias John

Articles

A monopole antenna, printed on low-cost laminate and fed by a microstrip line, is examined. These types of antennas are becoming popular in view of their broad bandwidth and low-profile structure, enabling easy integration as a terminal antenna. The move away from a classical ground plane (with normal radiator) is one of the attractive features of these antennas, but the full effects of the radiator and ground plane being on opposite sides of the same laminate are often not investigated. The effect of these ground planes on the impedance bandwidth and radiation pattern is investigated experimentally and numerically.

The Effect Of The Internal Field On The Ir Absorption Spectra Of Small Particles In Case Of 3d, 2d And 1d Size Confinement, Igor I. Shaganov, Tatiana S. Perova, R. Alan Moore, Kevin Berwick

Articles

The spectral properties of composite materials based on small particles under 1D, 2D, and 3D size confinement are described using a combination of dispersive internal field and effective media theory approaches. Calculations performed for a number of crystalline materials have shown that the peak position and intensity of the vibrational band of the material under conditions of 1D, 2D, and 3D size confinement are changed, whereas the bandwidth of the band remains the same. In the case of 3D confinement, the peak position of the spectrum of isolated “mesoparticles” ( ) appears to be very close to the intrinsic frequency …

Capitalising On Culture: An Evaluation Of Culture-Led Urban Regeneration Policy, Luke Binns

Articles

Municipal authorities throughout Western Europe are attempting to drive regeneration of their urban centres through policies designed to attract inward investment and tourism. In an attempt to woo these outside economic agents in, a variety of cultural consumption oriented policies have been developed and marketed. These include investment in hard cultural-infrastructure such as museums or art galleries, and in less physical aspects such as holding events like the European Capital of Culture. A polemical debate surrounds this use of cultural policy with a clearly economic agenda. This paper gives a brief synopsis of some culture-led regeneration models, addresses the validity …

Ecology, Morality And Synergism, Thomas Power

Articles

This short essay looks at the views of unorthodox members of three professions. Richard Douthwaite an anti-growth economist, James Lovelock a "mythical" scientist, and Yoneji Masuda, a Japanese guru of the Information Technology age. All three assume a re-orientation of human thinking. Douthwaite's "moral society", Lovelock's "ecological society" and Masuda's "synergistic society" have little basis in reality, despite their intrinsic appeal. Despite the "high knowledge consumption" of an information age, predicted by Masuda, history teaches us that knowledge has always been used by man to gain power and not to better the lot of mankind. There is no reason to …
