Differential Elastic Image Registration, Senthil Periaswamy, Hany Farid

Computer Science Technical Reports

We have applied techniques from differential motion estimation to the problem of automatic elastic registration of medical images. This method models the mapping between images as a locally affine but globally smooth warp. The mapping also explicitly accounts for variations in image intensities. This approach is simple and highly effective across a broad range of medical images. We show the efficacy of this approach on several synthetic and clinical images.

Detecting Steganographic Messages In Digital Images, Hany Farid

Computer Science Technical Reports

Techniques and applications for information hiding have become increasingly more sophisticated and widespread. With high-resolution digital images as carriers, detecting the presence of hidden messages has also become considerably more difficult. It is sometimes possible, nevertheless, to detect (but not necessarily decipher) the presence of embedded messages. The basic approach taken here works by finding predictable higher-order statistics of ``natural'' images within a multi-scale decomposition, and then showing that embedded messages alter these statistics.

What We Owe Our Children, They Their Children, ..., John E. Roemer, Roberto Veneziani

Cowles Foundation Discussion Papers

Egalitarian theorists, since Rawls, have in the main advocated equalizing some objective measure of individual well-being, such as primary goods, functioning, or resources, rather than subjective welfare. This discussion, however, has assumed, implicitly, a static environment. By analyzing a society that survives for many generations, we demonstrate that equality of opportunity for some objective condition is incompatible with human development over time. We argue that this incompatibility can be resolved by equalizing opportunities for welfare. Thus, ‘subjectivism’ seems necessary if we are to hope for a society which can both equalize opportunities and support the development of human capacity over …

Dynamical Relativistic Effects In Photoionization: Spin-Orbit-Resolved Angular Distributions Of Xenon 4d Photoelectrons Near The Cooper Minimum, H. Wang, G. Snell, Oliver Hemmers, M. M. Sant'anna, I. A. Sellin, N. Berrah, Dennis W. Lindle, P. C. Deshmukh, N. Haque, S. T. Manson

Environmental Studies Faculty Publications

Two decades ago, it was predicted [Y. S. Kim et al., Phys. Rev. Lett. 46, 1326 (1981)] that relativistic effects should alter the dynamics of the photoionization process in the vicinity of Cooper minima. The present experimental and theoretical study of the angular distributions of Xe 4d_3/2 and 4d_5/2 photoelectrons demonstrates this effect for the first time. The results clearly imply that relativistic effects are likely to be important for intermediate- Z atoms at most energies.

Environment-Induced Degradation And Crack-Growth Studies Of Candidate Target Materials: Aaa Task-4 Quarterly (June 1 – August 31, 2001) Report, Ajit K. Roy, Brendan O'Toole

Transmutation Sciences Materials (TRP)

The subject task entitled “Hydrogen-Induced Embrittlement of Candidate Target Materials for Applications in Spallation-Neutron-Target Systems” had commenced during the quarter ending on August 31, 2001. A research account has been established, contracts for both faculty and students have been prepared, and efforts are well underway to embark on the related research activities, as proposed.

As the title of this project implies, the primary objective of this task is to evaluate the effect of hydrogen on environment-assisted cracking of candidate materials for applications in spallationneutron- target (SNT) systems such as accelerator production of tritium (APT) and accelerator transmutation of waste (ATW). …

Changing Roles Of Title I Reading Teachers In Light Of New Provisions And Teamteaching Model, Abha Gupta, Eileen S. Oboler

Teaching & Learning Faculty Publications

We present the important and very complicated roles of the Title I Reading teacher in light of a new instructional paradigm: teamteaching. Following the 1994 reauthorization of Title I, Reading teachers often find themselves in multiple professional roles (Improving America's Schools Act, 1994). Based on observational data collected in our research on elementary school communities, five major categories of professional roles emerged (Oboler, 1993; Gupta and Oboler, 1998). We interpret Reading teachers' roles with respect to the new provisions found in the Interim Report, 1996, issued by the U.S. Department of Education (http://www.ed.gov/pubs/NatAssess), and Title I, Part A, Title I …

Inferring And Testing Hypotheses Of Cladistic Character Dependence By Using Character Compatibility, F. Robin O’Keefe, Peter J. Wagner

Biological Sciences Faculty Research

The notion that two characters evolve independently is of interest for two reasons. First, theories of biological integration often predict that change in one character requires complementary change in another. Second, character independence is a basic assumption of most phylogenetic inference methods, and dependent characters might confound attempts at phylogenetic inference. Previously proposed tests of correlated character evolution require a model phylogeny and therefore assume that nonphylogenetic correlation has a negligible effect on initial tree construction. This paper develops “tree-free” methods for testing the independence of cladistic characters. These methods can test the character independence model as a hypothesis before …

Carbon Dynamics In Peat Bogs: Insights From Substrate Macromolecular Chemistry, Kuder Tomasz, Michael A. Kruge

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The macromolecular compositions of subfossil plants from boreal Sphagnum bogs and restiad bogs (New Zealand) have been studied by pyrolysis-gas chromatography/mass spectrometry to evaluate the extent of degradation in the anoxic zone (catotelm) of a peat bog. Degradation of vascular plant polysaccharides was apparent only into the upper catotelm. Sphagnum was degraded more slowly than vascular plants, but no cessation of degradation was observed. The inferred rate of degradation varied depending on type of plant, extent of aerobic, precatotelmic degradation, and mode of litter deposition (rooting versus at the surface). Environmental forcing on anaerobic carbon dynamics would potentially be largest …

Progressive Transmission Of Spatial Data Over The Www: Challenges, James Carswell

Conference papers

Progressive transmission of raster images over the WWW has been successfully applied to provide users with coarser versions of the data before downloading a complete image. In the vector domain, progressive transmission remains a challenging topic. Increasing the level of detail of a vector dataset is a complex process that does not simply imply adding pixels to it. In this paper we present a survey of existing models for progressive transmission of spatial data and discuss open problems and challenges related to the progressive transmission of geographic maps in vector format. Finally, we propose a model based on a client-server …

Strong Enhancement Of Superconducting TC In Ferromagnetic Phases, Theodore R. Kirkpatrick, Dietrich Belitz, Thomas Vojta, Rajesh S. Narayanan

Physics Faculty Research & Creative Works

It is shown that the critical temperature for spin-triplet, p-wave superconductivity mediated by spin fluctuations is generically much higher in a Heisenberg ferromagnetic phase than in a paramagnetic one, due to the coupling of the magnons to the longitudinal magnetic susceptibility. Together with the tendency of the low-temperature ferromagnetic transition in very clean Heisenberg magnets to be of first order, this qualitatively explains the phase diagram recently observed in UGe₂.

Dual Differentiation: An Approach For Meeting The Curricular Needs Of Gifted Students With Learning Disabilities, Susan M. Baum, Carolyn R. Cooper, Terry W. Neu

Education Faculty Publications

Gifted students who experience difficulty with reading, mathematics, spelling, handwriting, and organization frequently become frustrated at an early age. Well-intentioned teachers attempt to remediate their weaknesses; yet, these youngsters still feel alone in the classroom. Moreover, their academic limitations often mask enormous talent, which seldom has an opportunity to surface. Thus, gifted learning-disabled students require curriculum that develops their special talents and provides them strategies to compensate for problematic weaknesses. This article discusses the dual characteristics of gifted learning-disabled students and suggests a unique curriculum that integrates both through talent development. Developed through Project HIGH HOPES, funded federally by the …

Ultraconvergence Of Zz Patch Recovery At Mesh Symmetry Points, Zhimin Zhang, Runchang Lin

Mathematics Research Reports

Ultraconvergence property of the Zienkiewicz-Zhu gradient patch recovery technique based on local discrete least squares fitting is established for a large class of even-order finite elements. The result is valid at all rectangular mesh symmetry points. Different smoothing strategies are discussed. Superconvergence recovery for the Q8 element is proved and ultraconvergence numerical examples are demonstrated.

Visual Displays Of Information: A Conceptual Taxonomy, Scott Warren

Librarian Publications

This paper creates a taxonomic model for visual information displays looking at three levels: information design (based on Edward Tufte’s work), information architecture, and information spaces. Special attention is paid to the use of spatial and navigational metaphors in visual systems as they affect the user’s experience. Especially interesting is how a user creates an “information space” – a mental model of what he has seen, how she keeps track of where she is within a system, and how these activities fit together with the data that is being sought. Mathematics is one area that holds promise for better understanding …

Nature Of Charge Carriers In Disordered Molecular Solids: Are Polarons Compatible With Observations?, Paul Ernest Parris, Vasudev M. Kenkre, David H. Dunlap

Physics Faculty Research & Creative Works

Polaronic theories for charge transport in disordered organic solids, particularly molecularly doped polymers, have been plagued by issues of internal consistency related to the magnitude of physical parameters. We present a natural resolution of the problem by showing that, in the presence of correlated disorder, polaronic carriers with binding energies Δ ~ 50 - 500 meV and transfer integrals J ~ 1 - 20 meV are completely consistent with the magnitudes of field and temperature dependent mobilities observed.

Composition Operators And A Pull-Back Measure Formula, Valentin Matache

Mathematics Faculty Publications

A pull-back measure formula obtained in some particular cases by E. A. Nordgren and this author is generalized in the framework of boundary measures for zero-free Nevanlinna class fuctions on the unit polydisk. The formula is used to characterize the zero-free Nevanlinna class functions which are solutions of Schröder's equation induced by a polydisk automorphism ϕ (i.e. to determine the zero-free functionsf belonging to the Nevanlinna class which are solutions of the functional equationf ° π=λf, for some constant λ), thus generalizing earlier results obtained by R. Mortini and this author.

Online Bayesian Tree-Structured Transformation Of Hmms With Optimal Model Selection For Speaker Adaptation, Shaojun Wang, Yunxin Zhao

Kno.e.sis Publications

This paper presents a new recursive Bayesian learning approach for transformation parameter estimation in speaker adaptation. Our goal is to incrementally transform or adapt a set of hidden Markov model (HMM) parameters for a new speaker and gain large performance improvement from a small amount of adaptation data. By constructing a clustering tree of HMM Gaussian mixture components, the linear regression (LR) or affine transformation parameters for HMM Gaussian mixture components are dynamically searched. An online Bayesian learning technique is proposed for recursive maximum a posteriori (MAP) estimation of LR and affine transformation parameters. This technique has the advantages of …
