A Presumption Of Innocence, Not Of Even Odds, Richard D. Friedman Jan 2000

A Presumption Of Innocence, Not Of Even Odds, Richard D. Friedman

Articles

Now I know how the Munchkins felt. Here I have been, toiling in the fields of Evidenceland for some years, laboring along with others to show how use of Bayesian probability theory can assist in the analysis and understanding of evidentiary problems.' In doing so, we have had to wage continuous battle against the Bayesioskeptics-the wicked witches who deny much value, even heuristic value, for probability theory in evidentiary analysis.2 Occasionally, I have longed for law-and-economics scholars to help work this field, which should be fertile ground for them.3 So imagine my delight when the virtual personification of law and …


Thickness Variation Of Self-Processing Acrylamide-Based Photopolymer And Reflection Holography, F. O'Neill, Justin Lawrence, J. Sheridan Jan 2000

Thickness Variation Of Self-Processing Acrylamide-Based Photopolymer And Reflection Holography, F. O'Neill, Justin Lawrence, J. Sheridan

Articles

There are many types of holographic recording material. The acrylamide-based recording material examined here has one significant advantage: it is self-processing. This simplifies the recording process and enables holographic interferometry to be carried out without the need for complex realignment procedures. However, the effect that the polymerization process has on the grating thickness must be examined. This question is fundamental to the material's use in holographic optical elements, as thickness variations affect the replay conditions of the produced elements. This paper presents a study of this thickness variation and reports for the first time the production of reflection holographic gratings …


Production Of A Signal By Irradiated Cells Which Leads To A Response In Unirradiated Cells Characteristic Of Initiation Of Apoptosis, Fiona Lyng, C. Seymour, C. Mothersill Jan 2000

Production Of A Signal By Irradiated Cells Which Leads To A Response In Unirradiated Cells Characteristic Of Initiation Of Apoptosis, Fiona Lyng, C. Seymour, C. Mothersill

Articles

This study investigated the ability of medium from irradiated cells to induce early events in the apoptotic cascade, such as mobilization of intracellular calcium, loss of mitochondrial membrane potential and increase in reactive oxygen species, in cells which were never exposed to radiation. Medium from irradiated human keratinocytes was harvested and transferred to unirradiated keratinocytes. Endpoints characteristic of the initiation of apoptosis were monitored for a period of 24 h following medium transfer. Clonogenic survival was also measured. Rapid calcium fluxes (within 30 s), loss of mitochondrial membrane potential, increases in reactive oxygen species (from 6 h after medium transfer), …


Development Of A Quality Control Procedure For Force Platforms, Jacinta Browne, Neil O'Hare Jan 2000

Development Of A Quality Control Procedure For Force Platforms, Jacinta Browne, Neil O'Hare

Articles

A force platform is a technical method of quantitatively assessing balance indirectly. The use of force platforms in physiotherapy departments has become more prominent over the last few years. However, the main drawback in the use of force platforms is the lack of comprehensive calibration procedures, which casts doubt on the results obtained with these systems. Existing calibration tests are limited to testing the spatial accuracy of the force platform. This paper describes a comprehensive quality control test procedure which was developed. It is proposed that the developed quality control test procedure could be used to test all types of …


Development Of A Novel Method For Assessing Balance: The Quantitative Posturography System, Jacinta Browne, Neil O'Hare Jan 2000

Development Of A Novel Method For Assessing Balance: The Quantitative Posturography System, Jacinta Browne, Neil O'Hare

Articles

Balance is the ability to maintain equilibrium while sitting or standing. There are a number of different methods, which are used to assess balance: technical methods such as Sway Magnetometry, Ataxia Meter and Force Platforms and clinical methods such as Functional Reach Test, Berg Balance Test and Fall Risk Index. The most frequently used technical method is the force platform. There are two types of Force Platform a static and a dynamic Force Platform of which the dynamic Force Platform has been found to be more sensitive at detecting impaired balance. The Quantitative Posturography System (QPS) described in this paper …


A Scene Similarity Metric For Matching Configurations Of Image Objects, James Carswell Jan 2000

A Scene Similarity Metric For Matching Configurations Of Image Objects, James Carswell

Articles

This paper proposes a novel solution to querying image databases by matching raster features to imagery completely in the raster/spatial domain using the shape of single features together with their spatial relations as the matching primitives. The core feature-based matching module combines a revised least-squares matching algorithm, to accomplish the matching process on binary images, with a unique implementation of a feature library that organizes and links query objects with their images in the database, thus enabling fast and efficient real-time retrieval of relevant imagery. The purpose is to extend this previous work of ours, which matches on the shape …

Performance Of Distributed Cfar Test Under Various Clutter Amplitudes, Chandrakanth H. Gowda, R. Viswanathan Oct 1999

Performance Of Distributed Cfar Test Under Various Clutter Amplitudes, Chandrakanth H. Gowda, R. Viswanathan

Articles

We evaluate the performances of several distributed constant false-alarm rate (CFAR) tests operating in different background clutter conditions. The analysis considers the detection of Rayleigh target in various clutters with the possibility of differing clutter power levels in the test cells of distributed radars. Numerical results studied for a two-radar system show how the false-alarm rate of the maximum order statistic (MOS) test changes with differences in the clutter power levels of the test cells. The analysis for the detection of Rayleigh target in Rayleigh clutter indicates that, with the power levels of differing test cells, the OR fusion rule …


The Jury And Scientific Evidence, Richard O. Lempert Sep 1999

The Jury And Scientific Evidence, Richard O. Lempert

Articles

Read court decisions and commentaries from 100, or evenfive years ago, and you will find that experts and scientific evidence were causing problems then just as they are causing problems now. I do not think that Daubert, Kumho Tire, or any change in a rule of evidence will keep expert scientific testimony from being a difficult area for the legal system. Yet we must still ask: "What are the best terms on which to deal with scientific experts, and how can weimprove the system?"


Sketch-Based Image Queries In Topographic Databases, James Carswell Jun 1999

Sketch-Based Image Queries In Topographic Databases, James Carswell

Articles

In this paper we present the development of a system prototype for sketch-based queries for the content-based retrieval of digital images from topographic databases. We discuss our overall strategy and associated algorithmic and implementation aspects, and present associated database design issues. The query tools devised in this research are employing user-provided sketches of the shape and spatial configuration of the object(s) which should appear in the images to be retrieved. Our matching tool is inspired by least-squares matching (lsm), and represents an extension of lsm to function with a variety of raster representations. Our strategy makes use of a hierarchical …


The Arccos And Lommel Formulations—Approximate Closed-Form Diffraction Corrections, Charles J. Daly, Navalgund A. H. Rao May 1999

The Arccos And Lommel Formulations—Approximate Closed-Form Diffraction Corrections, Charles J. Daly, Navalgund A. H. Rao

Articles

A closed-form frequency-domain formalism for spatially integrated diffraction corrections is proposed. Spatially integrated diffraction corrections are necessary when trying to characterize material with ultrasonic probing. In the case of piston transducers and point receivers, the Lommel diffraction formulation is used when the excitation is monochromatic, and the arccos diffraction formulation is used when the excitation is impulsive. The Lommel and arccos formulations are usually treated separately; here, they are connected. Specifically, the arccos diffraction formulation and Lommel diffraction formulation are shown to form an approximate Fourier transform pair. Since the Lommel formulation is amenable to closed-form spatial integration, Lommel functions …


Temperature Dependence Of Stark Width Of The 463.054 Nm Nii Spectral Line, Vladimir Milosavljevic, Ruzica Konjevic, Stevan Djenize Mar 1999

Temperature Dependence Of Stark Width Of The 463.054 Nm Nii Spectral Line, Vladimir Milosavljevic, Ruzica Konjevic, Stevan Djenize

Articles

Stark width of the 463.054 nm singly ionized nitrogen spectral line, that belong to transition, have been measured in a linear pulsed, low pressure, arc discharge. The working gas was helium-nitrogen-oxygen mixture. Electron densities of 0.751023 to 1.451023 were determined in the electron temperature range between 30000 K - 38000 K. The measured values have been compared with our calculated data, using the modified semiempirical approximation. On the basis of the agreement among experimental and theoretical Stark width data, the isolated 463.054 nm NII spectral line can be recommended as convenient spectral line for plasma diagnostics.


A Spatially Averaged Impulse Response For An Unfocused Piston Transducer, Charles J. Daly, Navalgund Rao Mar 1999

A Spatially Averaged Impulse Response For An Unfocused Piston Transducer, Charles J. Daly, Navalgund Rao

Articles

Fourier–Bessel theory is used to derive a closed-form solution for the spatially averaged velocity-potential impulse response associated with one-way diffraction from an unfocused piston transducer of radius a. The derivation provides additional insight into the problem of diffraction from an unfocused piston transducer.

Availability Cascades And Risk Regulation, Cass R. Sunstein, Timur Kuran Jan 1999

Availability Cascades And Risk Regulation, Cass R. Sunstein, Timur Kuran

Articles

An availability cascade is a self-reinforcing process of collective belief formation by which an expressed perception triggers a chain reaction that gives the perception increasing plausibility through its rising availability in public discourse. The driving mechanism involves a combination of informational and reputational motives: Individuals endorse the perception partly by learning from the apparent beliefs of others and partly by distorting their public responses in the interest of maintaining social acceptance. Availability entrepreneurs- activists who manipulate the content of public discourse-strive to trigger availability cascades likely to advance their agendas. Their availability campaigns may yield social benefits, but sometimes they …


An Economic Approach To The Law Of Evidence, Richard A. Posner Jan 1999

An Economic Approach To The Law Of Evidence, Richard A. Posner

Articles

In this article, Judge Richard A. Posner presents the first comprehensive economic analysis of the law of evidence. The article is presented in three parts. First, Judge Posner proposes and describes two possible economic models, both a search and a cost-minimization approach, to describe how evidence is obtained, presented, and evaluated. In both, he incorporates Bayes' theorem to examine rational decisionmaking. Second, he examines the evidence gathering process, comparing and contrasting, in economic terms, the "inquisitorial" and "adversarial" systems of justice. The inquisitorial system, at first glance, appears to be more economically efficient. This, though, may be illusory, a result …


What Is Constitutional Theory?, David A. Strauss Jan 1999

What Is Constitutional Theory?, David A. Strauss

Articles

Just what is constitutional theory? How can it be, as Professor Fallon rightly says, that constitutional theory is both descriptive and prescriptive, and is supposed to produce results that seem morally right but also some results that make the theory's proponents uncomfortable? In this Reply, Professor Strauss argues that a constitutional theory tries to draw upon bases of agreement that exist within a legal culture and to extend those agreed-upon principles to resolve more controversial issues. In our culture, for example, there is widespread agreement both on abstract principles- such as the idea that the text of the Constitution is …

Beyond The Formalism Debate: Expert Reasoning, Fuzzy Logic, And Complex Statutes, Edward Adams, Daniel Farber Jan 1999

Beyond The Formalism Debate: Expert Reasoning, Fuzzy Logic, And Complex Statutes, Edward Adams, Daniel Farber

Articles

Formalists and antiformalists continue to debate the utility of using legislative history and current social values to interpret statutes. Lost in the debate, however, is a clear model of how judges actually make decisions. Rather than focusing on complex problems presented by actual judicial decisions, formalists and antiformalists concentrate on stylized examples of simple statutes.In this Article, Professors Adams and Farber construct a more functional model of judicial decisionmaking by focusing on complex problems. They use cognitive psychological research on expert reasoning and techniques from an emerging area in the field of artificial intelligence, fuzzy logic, to construct their model. …


Economics V. Equity: Do Market-Based Environmental Reforms Exacerbate Environmental Injustice?, Stephen M. Johnson Jan 1999

Economics V. Equity: Do Market-Based Environmental Reforms Exacerbate Environmental Injustice?, Stephen M. Johnson

Articles

For almost three decades, the federal government and state governments have addressed environmental problems primarily through "command and control" regulation. Under this traditional approach, the federal government establishes uniform national pollution limits ("command") that the federal or state governments impose on individual polluters through a system of permits or other controls. However, as the command and control approach has eliminated many of the most prolific sources of pollution, the incremental cost of cleaning up the remaining pollution has risen dramatically, and command and control regulation has become politically less attractive. In addition, command and control regulation may be too rigid …


Note On The Voltammetry Of Ferrocene Carboxylate In Aqueous Solution, John Cassidy, John O'Gorman, M. Ronane, Enda Howard Jan 1999

Note On The Voltammetry Of Ferrocene Carboxylate In Aqueous Solution, John Cassidy, John O'Gorman, M. Ronane, Enda Howard

Articles

Cyclic voltammetry of ferrocene dicarboxylate in aqueous solutions at high pH, in the presence of oxygen, showed evidence of an EC' mechanism where the oxidised form of ferrocene dicarboxylate reacts with H02- , which had been produced at a lower potential. However, an analogous experiment with ferrocene carboxylate yielded a cyclic voltammogram with a post peak: following the anodic peak: for ferrocene carboxylate. The reason for the post peak: is not clear but may be due to a delay in the reaction between the oxidised form of ferrocene carboxylate and H02-.

2-(22, 8, 4) Designs Have No Blocks Of Type 3, Brendan Mckay, Stanislaw Radziszowski Jan 1999

2-(22, 8, 4) Designs Have No Blocks Of Type 3, Brendan Mckay, Stanislaw Radziszowski

Articles

Using computer algorithms we show that in any 2-(22,8,4) design there are no blocks of type 3, thus leaving as possible only types 1 and 2. Blocks of type 3, i.e. those which intersect two others in one point, are eliminated using the algorithms described in our previous paper. It was perhaps the second largest computation ever performed (after the solution to the RSA129 challenge), requiring more than a century of cpu time.
