Ccd Speckle Observations Of Binary Stars From The Southern Hemisphere, Elliott P. Horch, Zoran Ninkov, Robert W. Slawson Nov 1997

Ccd Speckle Observations Of Binary Stars From The Southern Hemisphere, Elliott P. Horch, Zoran Ninkov, Robert W. Slawson

Articles

We present 119 position angle and separation measures of 86 double stars observed by way of speckle interferometry with the University of Toronto Southern Observatory 60 cm telescope at Las Campanas, Chile. Speckle interferograms are recorded with a bare (unintensified) front-illuminated CCD in a fast subarray-readout mode. Position angles and separations are determined by a weighted least-squares fitting algorithm applied to the binary power spectra, and the 180-degree ambiguity in the position angle inherent in this approach is resolved by bispectral analysis. In this configuration the 60 cm telescope exhibits near-diffraction-limited performance. Initial results indicate that our separation measures have …


Gravity And Bf Theory Defined In Bounded Regions, V. Husain, Seth Major Sep 1997

Gravity And Bf Theory Defined In Bounded Regions, V. Husain, Seth Major

Articles

We study Einstein gravity in a finite spatial region. By requiring a well-defined variational principle, we identify all local boundary conditions, derive surface observables, and compute their algebra. The observables arise as induced surface terms, which contribute to a non-vanishing Hamiltonian. Unlike the asymptotically flat case, we find that there are an infinite number of surface observables. We give a similar analysis for SU(2) BF theory.

After The Dna Wars: Skirmishing With Nrc Ii, Richard O. Lempert Jul 1997

After The Dna Wars: Skirmishing With Nrc Ii, Richard O. Lempert

Articles

This article traces some of the controversies surrounding DNA evidence and argues that although many have been laid to rest by scientific developments confirmed in the National Research Council's second DNA report, there remain several problems which are likely to lead to continued questioning of standard ways prosecutors present DNA evidence. Although much about the report is to be commended, it falls short in several ways, the most important of which is in its support for presenting random match probabilities independent of plausible error rates. The article argues that although one can sympathize with the NRC committee's decision as an …


On The Stark Broadening Parameters Of The Two Nii Spectral Lines Of The 3d-4f Transition, Vladimir Milosavljevic, Stevan Djenize Jun 1997

On The Stark Broadening Parameters Of The Two Nii Spectral Lines Of The 3d-4f Transition, Vladimir Milosavljevic, Stevan Djenize

Articles

Stark parameters (width and shift) of two singly ionized nitrogen spectral lines, that belong to 3d-4f transition have been measured in a linear pulsed, low pressure, arc discharge in the nitrogen-oxygen plasma at a 54000 K electron temperature and at a 2.8×10 23 m−3 electron density. The measured values have been compared to the existing experimental and calculated data


Playing The "Culture Card": Trials In A Mutli-Cultural Democracy, Richard O. Lempert Apr 1997

Playing The "Culture Card": Trials In A Mutli-Cultural Democracy, Richard O. Lempert

Articles

As I write, the racial divide in America is said to be greater than at any time in the past 25 years.' Two events are blamed: the O.J. Simpson criminal trial and the Louis Farrakan led "Million Man March." That these events should exacerbate racial division is extraordinary. The Farrakan led march brought together between 400,000 and 800,000 black males to pledge that they would take the kind of responsibility for their actions and their families that white Americans have long argued they should take. The O.J. Simpson trial was more a "who done it" than a racial morality play. …


Evidence For The Specific Status Of The Honduran Lizards Formerly Referred To Ctenosaura Palearis (Reptilia: Squamata: Iguanidae), Larry Buckley, Ralph Axtell Feb 1997

Evidence For The Specific Status Of The Honduran Lizards Formerly Referred To Ctenosaura Palearis (Reptilia: Squamata: Iguanidae), Larry Buckley, Ralph Axtell

Articles

Ctenosaura melanosterna, a new species of spiny-tailed iguana, is described from the Aguan Valley and the Cayos Cochinos in Honduras. Its closest phylogenetic affinities are with C. palearis from the Motagua Valley in Guatemala with which it has previously been considered conspecific. Previous work on relationships within Ctenosaura presented evidence of a clade consisting of C. palearis (including the species described herein), C. bakeri, and C. oedirhina (de Queiroz, 1987a, 1987b; Kohler, 1995c). Data presented here adds additional support for this clade. Alternative biogeographic scenarios are discussed, with the conclusion that the current range of these species of Ctenosaura in …

The Problematics Of Moral And Legal Theory, Richard A. Posner Jan 1997

The Problematics Of Moral And Legal Theory, Richard A. Posner

Articles

In these Holmes Lectures, delivered a century after the publication of Oliver Wendell Holmes's great essay The Path of the Law, Judge Posner argues for an essentially Holmesian conception of the proper relations among modern normative moral philosophy ("academic moralism"), morality, and law. Academic moralism, he argues, lacks either the intellectual cogency or the emotional power to change people's beliefs or behavior; the power to do so resides in "moral entrepreneurs," which academic moralists emphatically are not. Academic moralism's lack of cogency disqualifies it to guide judicial decisionmaking even - in fact, especially - in cases involving controversial moral issues, …

A New Distributed Constant False Alarm Rate Detector, Hamid Amirmehrabi, R. Viswanathan Jan 1997

A New Distributed Constant False Alarm Rate Detector, Hamid Amirmehrabi, R. Viswanathan

Articles

A new constant false alarm rate (CFAR) test termed signal-plus-order statistic CFAR (S+OS) using distributed sensors is developed. The sensor modeling assumes that the returns of the test cells of different sensors are all independent and identically distributed. In the S+OS scheme, each sensor transmits its test sample and a designated order statistic of its surrounding observations to the fusion center. At the fusion center, the sum of the samples of the test cells is compared with a constant multiplied by a function of the order statistics. For a two-sensor network, the functions considered are the minimum of the order …

Diffraction From Polarization Holographic Gratings With Surface Relief In Side-Chain Azobenzene Polyesters, Izabela Naydenova, Ludmila Nikolova, Todor Todorov, N.C.R. Holme, P.S. Ramanujam, S. Hvilsted Jan 1997

Diffraction From Polarization Holographic Gratings With Surface Relief In Side-Chain Azobenzene Polyesters, Izabela Naydenova, Ludmila Nikolova, Todor Todorov, N.C.R. Holme, P.S. Ramanujam, S. Hvilsted

Articles

We investigate the polarization properties of holographic gratings in side-chain azobenzene polyesters in which an anisotropic grating that is due to photoinduced linear and circular birefringence is recorded in the volume of the material and a relief grating appears on the surface. A theoretical model is proposed to explain the experimental results, making it possible to understand the influence of the different photoinduced effects. It is shown that at low intensity the polarization properties of the diffraction at these gratings are determined by the interaction of the linear and circular photobirefringences, and at larger intensity the influence of the surface …


Abolish The Juvenile Court: Youthfulness, Criminal Responsibility, And Sentencing Policy, Barry C. Feld Jan 1997

Abolish The Juvenile Court: Youthfulness, Criminal Responsibility, And Sentencing Policy, Barry C. Feld

Articles

The juvenile court system should be abolished and all juvenile offenders should be integrated into the traditional criminal court system. The offenders' age should be taken into account during sentencing. The juvenile court system is a failure because a criminal punishment system cannot also be a social welfare system.

A Multibandwidth Probing Method For Tissue Scattering Microstructure Characterization, Navalgund Rao, Maria Helguera Jan 1997

A Multibandwidth Probing Method For Tissue Scattering Microstructure Characterization, Navalgund Rao, Maria Helguera

Articles

In medical ultrasound the normalized second intensity moments of the echo signal can depend on the imaging system resolution cell volume (axial and lateral resolution) in addiction to the scattering microstructure. The authors propose a multibandwidth probing technique in an attempt to separate the two. Theoretical relationships between second intensity moments, (scattering coefficients, scatterer spacing, and its randomness) and the system's cell volume are stablished. Experiments on water filled sponge structures with pore size varying from .5 mm to 2 mm and pig liver tissue are performed. The slope and intercept values from normalized second intensity moments versus (cell volume)-1 …


Psychophysical Evaluation Of Gamut Mapping Techniques Using Simple Rendered Images And Artificial Gamut Boundaries, Ethan Montag, Mark Fairchild Jan 1997

Psychophysical Evaluation Of Gamut Mapping Techniques Using Simple Rendered Images And Artificial Gamut Boundaries, Ethan Montag, Mark Fairchild

Articles

Using a paired comparison paradigm, various gamut mapping algorithms were evaluated using simple rendered images and artificial gamut boundaries. The test images consisted of simple rendered spheres floating in front of a gray background. Using CIELAB as our device-independent color space, cut-off values for lightness and chroma, based on the statistics of the images, were chosen to reduce the gamuts for the test images. The gamut mapping algorithms consisted of combinations of clipping and mapping the original gamut in linear piecewise segments. Complete color space compression in RGB and CIELAB was also tested. Each of the colored originals (R,G,B,C,M,Y, and …
