Complete View Of Stark Wave-Packet Evolution, M. B. Campbell, Thomas J. Bensky, Robert R. Jones Jun 1999

Complete View Of Stark Wave-Packet Evolution, M. B. Campbell, Thomas J. Bensky, Robert R. Jones

Physics

Picosecond laser pulses have been used to produce Rydberg wave packets in calcium atoms in the presence of a strong static electric field. The dynamics of the Stark wave packets have been observed by measuring the momentum-space probability distribution as a function of time. The full precession of the electronic orbital angular momentum, the appearance of a large-amplitude, linear oscillation of the electronic dipole moment, and a pronounced, periodic up-down asymmetry in the momentum distribution are all observed directly.

Influence Of Rare Regions On Magnetic Quantum Phase Transitions, Rajesh S. Narayanan, Thomas Vojta, Dietrich Belitz, Theodore R. Kirkpatrick Jun 1999

Influence Of Rare Regions On Magnetic Quantum Phase Transitions, Rajesh S. Narayanan, Thomas Vojta, Dietrich Belitz, Theodore R. Kirkpatrick

Physics Faculty Research & Creative Works

The effects of quenched disorder on the critical properties of itinerant quantum magnets are considered. Particular attention is paid to locally ordered rare regions that are formed in the presence of quenched disorder even when the bulk system is still in the nonmagnetic phase. It is shown that these local moments or instantons destroy the previously found critical fixed point in the case of antiferromagnets. In the case of itinerant ferromagnets, the critical behavior is unaffected by the rare regions due to an effective long-range interaction between the order parameter fluctuations.

Chemical and Materials Engineering Faculty Publications

A novel rapid prototyping technology incorporating a curved layer building style was developed. The new process, based on Laminated Object Manufacturing (LOM), was designed for efficient fabrication of curved layer structures made from ceramics and fiber reinforced composites. A new LOM machine was created, referred to as Curved Layer LOM. This new machine uses ceramic tapes and fiber prepregs as feedstocks and fabricates curved structures on a curved-layer by curved-layer basis. The output of the process is a three dimensional "green" ceramic that is capable of being processed to a seamless, fully dense ceramic using traditional techniques. A detailed description …

Parents' Predictions Of Children's Responses On The Piers-Harris Children's Self-Concept Scale, Sheila J. Murphy Jun 1999

Parents' Predictions Of Children's Responses On The Piers-Harris Children's Self-Concept Scale, Sheila J. Murphy

Theses

The Piers-Harris Children's Self-Concept Scale was administered to 50 fifth-grade students (30 boys and 20 girls) attending a suburban, middle class public school. Their parents (45 mothers, 3 fathers, 1 mother/father combined, 1 unidentified) responded to the same self-concept measure "as they believed their child would respond." Mean scores for parents were higher than mean scores for students in six of the seven scales, suggesting a tendency for parents to overestimate the self-attitudes of their children. However, two-tailed! tests for paired observations showed significant mean differences for only two scales. Pearson product-moment correlations revealed significant positive relationships between students' scores …

On The Geometries Of Conic Section Representation Of Noisy Object Boundaries, Qiuming Zhu Jun 1999

On The Geometries Of Conic Section Representation Of Noisy Object Boundaries, Qiuming Zhu

Computer Science Faculty Publications

This paper studies some geometrical properties of conic sections and the utilization of these properties for the generation of conic section representations of object boundaries in digital images. Several geometrical features of the conic sections, such as the chord, the characteristic point, the guiding triangles, and their appearances under the tessellation and noise corruption of the digital images are discussed. The study leads to a noniterative algorithm that takes advantage of these features in the process of formulating the conic section parameters and generating the approximations of object boundaries from the given sequences of edge pixels in the images. The …

Multiple Isotopic Studies Of Calcium Carbonate Growths In Concrete Structures, Danielle M. Schmitt Jun 1999

Multiple Isotopic Studies Of Calcium Carbonate Growths In Concrete Structures, Danielle M. Schmitt

Masters Theses

Secondary minerals, predominantly carbonates, forming under concrete structures have received attention in terms of their possible role in the degradation of their hosts. δ13C and δ18O analyses of several calcium carbonate growths collected from bridges in Michigan and New York were performed. The δ13C and δ18O values clustered around -24.7 ± 1(PDB) and 13.7 ± 1(SMOW) ‰, respectively. A positive δ18O- δ13C correlation suggests kinetically driven precipitation involving atmospheric CO2• 14C activities determined for select samples support the theory that atmospheric CO2 is involved …

Comment On "Relativistic Correction Of The Generalized Oscillator Strength Sum Rules", P.T. Leung, Scott M. Cohen Jun 1999

Comment On "Relativistic Correction Of The Generalized Oscillator Strength Sum Rules", P.T. Leung, Scott M. Cohen

Physics Faculty Publications and Presentations

Romero and Aucar [Phys. Rev. A 57, 2212 (1998)] have found a vanishing result for the relativistic correction to the dipole sum rule ∆S1 for a one-electron system. They have given a result for the dipole sum rule ∆S2 as well. We argue that these results are both incorrect and show explicitly that their approach yields a nonvanishing result for ∆S1. The corrected result is in agreement with that which we have obtained in a recent paper, in which we present explicit expressions for ∆S1, ∆S2, and several other more general sum rules.

An Analysis Of Nine K-12 School Districts That Have Established Membership With The Coalition Of Essential Schools, Shari A. Peters Kitchen Jun 1999

An Analysis Of Nine K-12 School Districts That Have Established Membership With The Coalition Of Essential Schools, Shari A. Peters Kitchen

Dissertations

In the late 1970s, Ted Sizer, professor of education at Brown University, and a team of researchers traveled the country visiting dozens of secondary schools. The purpose of these visits was to understand the American high school by observing it firsthand. Sizer reported his findings in 1984 in Horace's Compromise: The Dilemma of the American High School.

In response to the compromises raised in Horace's Compromise, 12 schools volunteered to become the Coalition of Essential Schools. The Coalition rests on a set of nine Common Principles, which include intellectual rigor, simple and universal goals, personalized school, graduation by exhibitions …


A Comprehensive Approach For Evaluation Of Groundwater Vulnerability To Contamination, Shafiul H. Chowdhury Jun 1999

A Comprehensive Approach For Evaluation Of Groundwater Vulnerability To Contamination, Shafiul H. Chowdhury

Dissertations

Groundwater vulnerability to contamination from surface sources was evaluated for Nottawa Creek Watershed, Calhoun County Michigan using AQUIPRO and DRASTIC vulnerability methods. A geographic information system (GIS) was used to analyze and map the data. Forty groundwater samples were collected following a statistical sampling protocol from private wells. Samples were analyzed for nitrate-N and atrazine. Atrazine was not detected (detection limit 0.1 ppb) in any of the samples. Five samples contained detectable nitrate-N (detection limit 0.05 mg/L). Due to insufficient chemical data, the relative AQUIPRO and DRASTIC vulnerability scores could not be compared with the frequency of occurrences o f …


Period-Doubling Behavior In Frontal Polymerization Of Multifunctional Acrylates, Jonathan Masere, Felicia Stewart, Timothy Meehan, John A. Pojman Jun 1999

Period-Doubling Behavior In Frontal Polymerization Of Multifunctional Acrylates, Jonathan Masere, Felicia Stewart, Timothy Meehan, John A. Pojman

Faculty Publications

Front dynamics in the frontal polymerization of two multifunctional acrylate monomers, 1,6-hexanediol diacrylate (HDDA) and trimethylolpropane ethoxylate triacrylate (TMPTA), with Lupersol 231 [1,1-di(t-butylperoxy)-3,3,5-trimethylcyclohexane] as the initiator, are studied. In most frontal polymerization systems, the dynamics are associated with a planar front propagating through the sample. However, in some cases, front behavior can be altered: the front becomes nonplanar characterized by complex patterns like spin modes and pulsations. To determine how these periodic and aperiodic modes arise, reactant solutions consisting of HDDA diluted with diethyl phthalate (DEP) and TMPTA diluted with dimethyl sulfoxide (DMSO) were used in the study. …


Verifying The Teaching Of Analogies To Fourth Grade Students, Terese A. Byrne Jun 1999

Verifying The Teaching Of Analogies To Fourth Grade Students, Terese A. Byrne

Critical and Creative Thinking Capstones Collection

The proliferation of technology and the information it makes available to all has forced education to realign itself to meet the changing needs of today's students. A shift away from amassing information, toward the development of critical thinking skills, presents teachers with new questions. What skills are appropriate to teach at a given age or level, and how can those skills be developed? This project takes one of those skills, analogies, and investigates the degree of success a teacher might expect in teaching them to fourth grade students. The project was designed as a data generating study. Fifty-seven fourth grade …

Deterrence And Damages: The Multiplier Principle And Its Alternatives, Richard Craswell Jun 1999

Deterrence And Damages: The Multiplier Principle And Its Alternatives, Richard Craswell

Michigan Law Review

One purpose of fines and damage awards is to deter harmful behavior. When enforcement is imperfect, however, so the probability that any given violation will be punished is less than 100%, the law's deterrent effect is usually thought to be reduced. Thus, it is often said that the ideal penalty (insofar as deterrence is concerned) equals the harm caused by the violation multiplied by one over the probability of punishment. For example, if a violation faces only a 25% (or one-in-four) chance of being punished, on this view the optimal penalty would be four times the harm caused by the …
