Breakpoint Skeletal Representation And Compression Of Document Images, William A. Barrett, Bryan S. Morse, Eric N. Mortensen Mar 1998

Breakpoint Skeletal Representation And Compression Of Document Images, William A. Barrett, Bryan S. Morse, Eric N. Mortensen

Faculty Publications

We present a new method for representation and (lossy) compression of bitonal document images. The technique extracts a skeletal medial axis from each object using a true Euclidean distance map of the image and then finds piecewise linear breakpoints in the skeleton to create a breakpoint skeletal representation, bps, (Fig. 1). The bps is encoded for each object as a set of triples {, <Δx2,Δy2,Δr2>, . . . <Δxn,Δyn,Δrn>} where contains the coordinate and distance (radius, r1) of the initial breakpoint from the closest point on the perimeter of the object and <Δxi,Δyi,Δri> represents the difference in location and radius between …


Determination Of The Asymmetry Parameter And Scattering Coefficient Of Turbid Media From Spatially Resolved Reflectance Measurments, Matthew R. Jones, Yukio Yamada Mar 1998

Determination Of The Asymmetry Parameter And Scattering Coefficient Of Turbid Media From Spatially Resolved Reflectance Measurments, Matthew R. Jones, Yukio Yamada

Faculty Publications

We present a technique for determining the asymmetry parameter and scattering coefficient of turbid media from spatially resolved reflectance measurements. This technique will contribute to the development of medical applications in which it is necessary to predict the distribution and propagation of light in tissue. Based on Monte Carlo simulations, we derived correlations which relate the reduced scattering coefficient and the asymmetry parameter to the relative reflectance curve. Initial estimates of the optical properties are obtained from these correlations. Final values are obtained by adjusting the optical parameters and repeating the Monte Carlo simulations until the simulated reflectance pattern matches …

The NOMAD experiment is a short base-line search for νμ − ντ oscillations in the CERN neutrino beam. The ντ's are searched for through their charged current interactions followed by the observation of the resulting τ− through its electronic, muonic or hadronic decays. These decays are recognized using kinematical criteria necessitating the use of a light target which enables the reconstruction of individual particles produced in the neutrino interactions. This paper describes the various components of the NOMAD detector: the target and muon drift chambers, the electromagnetic and hadronic calorimeters, the preshower and transition radiation …


Computer Simulations Of Branched Alkanes: The Effect Of Side Chain And Its Position On Rheological Behavior, Richard L. Rowley, Tapani A. Pakkanen, Maija Lahtela, Mikko Linnolahti Feb 1998

Computer Simulations Of Branched Alkanes: The Effect Of Side Chain And Its Position On Rheological Behavior, Richard L. Rowley, Tapani A. Pakkanen, Maija Lahtela, Mikko Linnolahti

Faculty Publications

Nonequilibrium molecular dynamics simulations have been performed on model fluids representing eicosane isomers in order to investigate the effect of branching and side chain position on fluid rheology. A heterogeneous, united-atom model with 20 Lennard-Jones interaction sites located at carbon centers was used to model the fluids. Vibrations and bond rotations were frozen, but torsional rotation was included. It was found that viscosity increases significantly from the n-alkane structure to a branch on carbon 2, but the movement of the branch along the carbon backbone has a smaller increasing than decreasing effect. The size of the group in a branched …


Recognizing Constant Curvature Discrete Groups In Dimension 3, J. W. Cannon, E. L. Swenson Feb 1998

Recognizing Constant Curvature Discrete Groups In Dimension 3, J. W. Cannon, E. L. Swenson

Faculty Publications

We characterize those discrete groups Gwhich can act properly discontinuously, isometrically, and cocompactly on hyperbolic 3-space H^3 in terms of the combinatorics of the action of G on its space at infinity. The major ingredients in the proof are the properties of groups that are negatively curved (in the large) (that is, Gromov hyperbolic), the combinatorial Riemann mapping theorem, and the Sullivan-Tukia theorem on groups which act uniformly quasiconformally on the 2-sphere.


Some Harmonic N-Slit Mappings, Michael Dorff Feb 1998

Some Harmonic N-Slit Mappings, Michael Dorff

Faculty Publications

The class SH consists of univalent, harmonic, and sense-preserving functions f in the unit disk, ∆, such that f = h+g where h(z) = (see PDF), g(z) = (see PDF) . SOH will denote the subclass with b1 = 0. We present a collection of n-slit mappings (n ≥ 2) and prove that the 2-slit mappings are in SH while for n ≥ 3 the mappings are in SOH. Finally we show that these mappings establish the sharpness of a previous theorem by Clunie and Sheil-Small while disproving a conjecture about the inner mapping radius.


Thermal Equilibrium Of Warm Clouds Of Charge With Small Aspect Ratio, Deborah L. Paulson, Ross L. Spencer Feb 1998

Thermal Equilibrium Of Warm Clouds Of Charge With Small Aspect Ratio, Deborah L. Paulson, Ross L. Spencer

Faculty Publications

Global thermal equilibrium computations are presented for non-neutral plasmas whose radial size is much larger than their axial thickness. Axial and radial density profiles are computed for both ideal and nonideal Penning trap fields. Simple results are obtained in the limits of both low and high central density. Comparison is made to the grid calculations of Mason et al. [Phys. Plasmas 3 (5), 1502 (1996)].

The Alien-Citizen Paradox And Other Consequences Of U.S. Colonialism, Ediberto Román Jan 1998

The Alien-Citizen Paradox And Other Consequences Of U.S. Colonialism, Ediberto Román

Faculty Publications

This Article examines the United States' 100-year-old failed promise. In addition to detailing the unequal citizenship status of the people of Puerto Rico, this Article examines the role that racial and ethnic-based prejudice has played in this issue. 34 Essentially, this Article seeks to compare the traditional legal and political rhetoric of American inclusiveness and the virtues of U.S. citizenship to the reality of colonialism and the impact white supremacy has had on U.S. colonial history. By addressing the subordinated status of "aliencitizens," this Article illustrates the incompatibility of equality under colonialism. As Congress addresses the question of Puerto Rico's …


Constitutional Fidelity And The Commerce Clause: A Reply To Professor Ackerman, Elizabeth Price Foley, Elizabeth C. Price Jan 1998

Constitutional Fidelity And The Commerce Clause: A Reply To Professor Ackerman, Elizabeth Price Foley, Elizabeth C. Price

Faculty Publications

Can the Constitution be legitimately, albeit implicitly, amended by the Supreme Court? The possibility of implicit constitutional amendment - most forcefully advocated by Professor Bruce Ackerman as "transformative" Supreme Court decisions - has been articulated to justify, legitimate, and entrench various radical reinterpretations of the Constitution, most notably the New Deal Court's vast expansion of the power to regulate commerce. The article concludes that such implicit constitutional amendments are theoretically illegitimate and provide strong disincentives for "We the People" to become politically active in order to "correct" flaws in the original Constitution or interpretations thereof that are deemed no longer …

The Great Transformation Of Regulated Industries Law, Joseph D. Kearney, Thomas W. Merrill Jan 1998

The Great Transformation Of Regulated Industries Law, Joseph D. Kearney, Thomas W. Merrill

Faculty Publications

The nation's approach to regulating its transportation, telecommunications, and energy industries has undergone a great transformation in the last quarter-century. The original paradigm of regulation, which was established with the Interstate Commerce Act's regulation of railroads beginning in 1887, was characterized by legislative creation of an administrative agency charged with general regulatory oversight of particular industries. This approach did not depend on whether the regulated industry was naturally competitive or was a natural monopoly, and it was designed to advance accepted goals of reliability and, in particular, non-discrimination. By contrast, under the new paradigm, which is manifested most clearly in …

Crime Or Punishment: The Parental Corporal Punishment Defense - Reasonable And Necessary, Or Excused Abuse, Kandice Johnson Jan 1998

Crime Or Punishment: The Parental Corporal Punishment Defense - Reasonable And Necessary, Or Excused Abuse, Kandice Johnson

Faculty Publications

The parental right to use physical force to discipline and restrain children is a privilege firmly rooted in the American system of jurisprudence. This privilege is often asserted as a defense when parents are charged with a crime of aggression against their child. While the privilege to use disciplinary force is universally recognized as a defense in criminal actions, it is equally acknowledged that child abuse is a pervasive reality of American life. This article postulates that current laws, addressing assertion of the parental privilege defense in criminal actions, fail either to provide adequate guidance to parents or to sufficiently …

Faculty Publications

We analyzed the European genetic contribution to 10 populations of African descent in the United States (Maywood, Illinois; Detroit; New York; Philadelphia; Pittsburgh; Baltimore; Charleston, South Carolina; New Orleans; and Houston) and in Jamaica, using nine autosomal DNA markers. These markers either are population-specific or show frequency differences >45% between the parental populations and are thus especially informative for admixture. European genetic ancestry ranged from 6.8% (Jamaica) to 22.5% (New Orleans). The unique utility of these markers is reflected in the low variance associated with these admixture estimates (SEM 1.3%-2.7%). We also estimated the male and female European contribution to …


Reforming The Law: The Payment Rule As A Paradigm , Dale A. Whitman Jan 1998

Reforming The Law: The Payment Rule As A Paradigm , Dale A. Whitman

Faculty Publications

The concept of negotiability of promissory notes is solidly entrenched in American commercial law. It derives from the English common law notion that a negotiable instrument is a reification of the obligation it describes; the instrument is regarded as a tangible form of the obligation. This notion has multiple ramifications, but three stand out. The first is the holder in due course doctrine which asserts that, when a negotiable instrument is transferred by the correct process (negotiation, which requires delivery of the paper) to someone with the right qualities (good faith, lack of notice, and payment of value), the maker …


Third Party Intervention And Joinder As Of Right In International Arbitration: An Infringement Of Individual Contract Rights Or A Proper Equitable Measure?, S. I. Strong Jan 1998

Third Party Intervention And Joinder As Of Right In International Arbitration: An Infringement Of Individual Contract Rights Or A Proper Equitable Measure?, S. I. Strong

Faculty Publications

Arbitration has long been called a creature of contract, a dispute resolution mechanism that has no form or validity outside the four corners of the parties' arbitration agreement. Some feel, however, that it may be time to change this narrow interpretation of arbitration's function and scope, and nowhere is this need for reform more apparent than in the realm of multi-party international disputes. Arbitration has taken on an increasingly important role in international commercial transactions and has become the preferred dispute resolution mechanism in many types of transnational contracts. Although there are any number of reasons why this may be …


Starburst-Like Dust Extinction In The Small Magellanic Cloud, Karl D. Gordon, Geoffrey C. Clayton Jan 1998

Starburst-Like Dust Extinction In The Small Magellanic Cloud, Karl D. Gordon, Geoffrey C. Clayton

Faculty Publications

The recent discovery that the ultraviolet (UV) dust extinction in starburst galaxies is similar to that found in the Small Magellanic Cloud (SMC) motivated us to reinvestigate the UV extinction found in the SMC. We have been able to improve significantly on previous studies by carefully choosing pairs of well-matched reddened and unreddened stars. In addition, we benefited from the improved signal-tonoise ratio of the NEWSIPS International Ultraviolet Explorer (WE) data and the larger sample of SMC stars now available. Searching the WE Final Archive, we found only four suitable early-type stars that were significantly reddened and had well-matched comparison …

Overt And Relational Aggression In Russian Nursery-School-Age Children: Parenting Style And Marital Linkages., C. H. Hart, D. A. Nelson, C. C. Robinson, S. F. Olsen, M. K. Mcneilly-Choque

Faculty Publications

Maternal and paternal parenting styles and marital interactions linked to childhood aggressive behavior as described in Western psychological literature were measured in an ethnic Russian sample of 207 families of nursery-school-age children. Results corroborated and extended findings from Western samples. Maternal and paternal coercion, lack of responsiveness, and psychological control (for mothers only) were significantly correlated with children's overt aggression with peers. Less responsiveness (for mothers and fathers) and maternal coercion positively correlated with relational aggression. Some of these associations differed for boys versus girls. Marital conflict was also linked to more overt and relational aggression for boys. When entered …


Computation On Metric Spaces Via Domain Theory, Jimmie Lawson Jan 1998

Computation On Metric Spaces Via Domain Theory, Jimmie Lawson

Faculty Publications

The purpose of this paper is to survey recent approaches to realizing (or embedding) a Polish space as the set of maximal points of a continuous domain. Such realizations provide a convenient framework in which to model certain computational algorithms on the space and a useful alternate approach via the probabilistic power domain to measure theory and integraion on the space. © 1998 Elsevier Science B.V.


The Second Stekloff Eigenvalue And Energy Dissipation Inequalities For Functionals With Surface Energy, Robert Lipton Jan 1998

The Second Stekloff Eigenvalue And Energy Dissipation Inequalities For Functionals With Surface Energy, Robert Lipton

Faculty Publications

A functional with both bulk and interfacial surface energy is considered. It corresponds to the energy dissipated inside a two-phase electrical conductor in the presence of an electrical contact resistance at the two-phase interface. The effect of embedding a highly conducting particle into a matrix of lesser conductivity is investigated. We find the criterion that determines when the increase in surface energy matches or exceeds the reduction in bulk energy associated with the particle. This criterion is general and applies to any particle with Lipschitz continuous boundary. It is given in terms of the of the second Stekloff eigenvalue of …
