Pocket Deformable Mirror For Adaptive Optics Applications, Leonid A. Beresnev, Mikhail Vorontsov, Peter Wangsness

Electrical and Computer Engineering Faculty Publications

Adaptive/active optical elements are designed to improve optical system performance in the presence of phase aberrations. For atmospheric optics and astronomical applications, an ideal deformable mirror should have sufficient frequency bandwidth for compensation of fast changing wave front aberrations induced by either atmospheric turbulences or by turbulent air flows surrounding a flying object (air optical effects). In many applications, such as atmospheric target tracking, remote sensing from flying aircraft, boundary layer imaging, laser communication and laser beam projection over near horizontal propagation paths the phase aberration frequency bandwidth can exceed several kHz. These fast-changing aberrations are currently compensated using relatively …

Adaptive Beam Director For A Tiled Fiber Array, Mikhail Vorontsov, Jim F. Riker, Ernst Polnau, Svetlana Lachinova, Venkata S. Rao Gudimetla

Electrical and Computer Engineering Faculty Publications

We present the concept development of a novel atmospheric compensation system based on adaptive tiled fiber array architecture operating with target-in-the-loop scenarios for directed beam applications. The adaptive tiled fiber array system is integrated with adaptive beam director (ABD). Wavefront control and sensing functions are performed directly on the beam director telescope primary mirror. The beam control of the adaptive tiled fiber array aims to compensate atmospheric turbulence-induced dynamic phase aberrations and results in a corresponding brightness increase on the illuminated extended object. The system is specifically designed for tiled fiber system architectures operating in strong intensity scintillation and speckle-modulation …

Enhanced Cerenkov Second-Harmonic Generation In Patterned Lithium Niobate, Cong Deng, Joseph W. Haus, Andrew Sarangan, Aziz Mahfoud, Concita Sibilia, Michael Scalora, Aleksei M. Zheltikov

Electro-Optics and Photonics Faculty Publications

We present experimental results of second harmonic generation enhancement through the resonance of the band edge in a photonic crystal based on lithium niobate. Proton exchange technique was used to fabricate a waveguide near the surface of the lithium niobate substrate. The photonic crystal structure over the waveguide was made by UV laser interferometry. Subsequently experiments were designed to quantify the Cerenkov second-harmonic generation (CSHG) radiated into the substrate. The SHG radiated inside the waveguides was also experimentally investigated. In our experiments, the second guided mode of the waveguide was tuned to the band edge resonance to enhance the second …

The Dynamics Of Newton's Method On Cubic Polynomials, Shannon N. Miller

Theses, Dissertations and Capstones

The field of dynamics is itself a huge part of many branches of science, including the motion of the planets and galaxies, changing weather patterns, and the growth and decline of populations. Consider a function f and pick x0 in the domain of f . If we iterate this function around the point x0, then we will have the sequence x0, f (x0), f (f (x0)), f (f (f (x0))), ..., which becomes our dynamical system. We are essentially interested in the end behavior of this system. Do …

Humor And Laughter May Influence Health: Ii. Complementary Therapies And Humor In A Clinical Population, Mary Payne Bennett, Cecile Lengacher

Nursing Faculty Publications

Our results support a connection between sense of humor and self-reported physical health, however, it is difficult to determine the relationship to any specific disease process. Whereas relationships between sense of humor and self-reported measures of physical well-being appear to be supported, more research is required to determine interrelationships between sense of humor and well-being.

Humor And Laughter May Influence Health. I. History And Background, Mary Payne Bennett, Cecile A. Lengacher

Nursing Faculty Publications

Articles in both the lay and professional literature have extolled the virtues of humor, many giving the impression that the health benefits of humor are well documented by the scientific and medical community. The concept that humor or laughter can be therapeutic goes back to biblical times and this belief has received varying levels of support from the scientific community at different points in its history. Current research indicates that using humor is well accepted by the public and is frequently used as a coping mechanism. However, the scientific evidence of the benefits of using humor on various health related …

Importing Extended Producer Responsibility For Electronic Equipment Into The United States, Chad Raphael, Ted Smith

Communication

Extended Producer Responsibility (EPR) is a policy approach that holds manufacturers accountable for the full costs of their products at every stage in their life cycle. EPR typically involves requiring that producers take back their products at the end of their useful lives, or pay a recycling contractor to do so, thereby internalizing the costs of recycling or disposal in a manufacturer’s bottom line. When companies know that they will bear the costs of product return and recycling, they are more likely to redesign their products for easier and safer handling at each step in the life cycle. This approach …

Ichthyofaunal Assemblages In Three Approximate But Ecologically Diverse Streams In Clark County, Arkansas, C. Renn Tumlison, Scott Jordan, Lesley Self, Henry W. Robison

Journal of the Arkansas Academy of Science

Three tributaries to the Ouachita River in eastern Clark County, Arkansas, empty into the river within a collective distance of about 9 km. The streams drain basins derived from the Wilcox formation, partially overlain by terrace and alluvial deposits. Despite their proximity, the streams are very different: L'Eau Frais has a gravel substrate and was recognized by the French as a cool water stream, Tupelo Creek is a bottomland stream from which numerous Water Tupelo (Nyssa aquatica) emerge, and Saline Bayou was named due to its marked salinity. We studied the assemblages of fishes in these 3 very different drainages …

Behavioral Economics: Human Errors And Market Corrections, Richard A. Epstein

Faculty Articles

As a matter of first principles, it seems impossible to deny two facts about human nature. First, people often make serious mistakes in deciding important matters. Second, people often find it hardest to keep their emotions in check when it matters the most. My task here is not to deny these obvious truths, but to ask about their significance in certain transactional settings. One key link in that inquiry is how individuals who suffer from both cognitive and emotional impairments can be regarded as "rational." Stated otherwise, do people with these dual limitations by and large make responsible decisions in …

Using A Robotic Arm To Evaluate The Programming Ability Of K-12 Educators, Antoinette P. Bruciati

Education Faculty Publications

This usability study measured the ability of educators to master advanced computer programming concepts through the OWI Robotic Arm Trainer and PC Interface. Research findings revealed that the lack of prior computer programming experience did not impact the ability of each participant to successfully program his/her robotic arm. However, the absence of a detailed instructional manual detracted from the product’s usability. Future directions for research and the suitability of the robotic arm for use in an online teacher preparation course in robotics technologies are discussed at the conclusion of this paper.

Probabilisticmodel-Based Cell Tracking, Nezamoddin Nezamoddini-Kachouie, Paul Fieguth, Eric Jervis

Mathematics and System Engineering Faculty Publications

The study of cell behavior is of crucial importance in drug and disease research. The fields of bioinformatics and biotechnology rely on the collection, processing, and analysis of huge numbers of biocellular images, including cell features such as cell size, shape, and motility. However manual methods of inferring these values are so onerous that automated methods of cell tracking and segmentation are in high demand. In this paper, a novel model-based cell tracker is designed to locate and track individual cells. The proposed cell tracker has been successfully applied to track hematopoietic stem cells (HSCs) based on identified cell locations …

On A Class Of Two-Point Boundary Value Problems With Singular Boundary Conditions, Ravi P. Agarwal, To Fu Ma

Mathematics and System Engineering Faculty Publications

A new existence theory for a class of second order two-point boundary value problems with nonlinear boundary conditions which can blow up in finite intervals is established. The proofs are based on the dual variational principle and the critical point theory.

Generalized Flow Invariance For Differential Inclusions, Tarun Gnana Bhaskar, V. Lakshmikantham

Mathematics and System Engineering Faculty Publications

We introduce a generalized notion of invariance for differential inclusions, using a proximal aiming condition in terms of proximal normals. A set of sufficient conditions for the weak and strong invariance in the generalized sense are presented.

The Architecture Of Inclusion: Advancing Workplace Equity In Higher Education, Susan Sturm

Faculty Scholarship

The path to workplace'equality has become a difficult one to navigate. No one can safely rely upon the strategies developed in the 1960s and 1970s to integrate workplaces. Employers face legal and political challenges both for failing to diversify their workplaces and for diversity efforts to overcome that failure. Civil rights and women's rights advocates battle to hold on to the litigation victories of the past, even as they acknowledge judicial remedies' shrinking availability and limited efficacy in addressing many aspects of current-day equality. Anti-discrimination regulators contend with inadequate resources to carry out their traditional enforcement activities, as well as …

The Three Goals Of Taxation, Reuven S. Avi-Yonah

Articles

The current debate in the United States about whether the income tax should be replaced with a consumption tax has been waged on the traditional grounds for evaluating tax policy: efficiency, equity, and administrability. For example, Joseph Bankman and David Weisbach recently argued for the superiority of an ideal consumption tax over an ideal income tax on three grounds: First, that the consumption tax is more efficient because it does not discriminate between current and future consumption,' while both income and consumption taxes have identical effect on work effort. Second, that the consumption tax is at least as good at …

Improving Criminal Jury Decision Making After The Blakely Revolution, J. J. Prescott, Sonja B. Starr

Articles

The shift in sentencing fact-finding responsibility triggered in many states by Blakely v. Washington may dramatically change the complexity and type of questions that juries will be required to answer. Among the most important challenges confronting legislatures now debating the future of their sentencing regimes is whether juries are prepared to handle this new responsibility effectively - and, if not, what can be done about it. Yet neither scholars addressing the impact of Blakely nor advocates of jury reform have seriously explored these questions. Nonetheless, a number of limitations on juror decision making seriously threaten the accuracy of verdicts in …

Muslim Profiles Post-9/11: Is Racial Profiling An Effective Counterterrorist Measure And Does It Violate The Right To Be Free From Discrimination?, Bernard E. Harcourt

Faculty Scholarship

Racial profiling as a defensive counterterrorism measure necessarily implicates a rights trade-off: if effective, racial profiling limits the right of young Muslim men to be free from discrimination in order to promote the security and well-being of others. Proponents of racial profiling argue that it is based on simple statistical fact and represents just smart law enforcement. Opponents of racial profiling, like New York City police commissioner Raymond Kelly, say that it is dangerous and just nuts.

As a theoretical matter, both sides are partly right. Racial profiling in the context of counterterrorism measures may increase the detection of terrorist …

Image-Based Nanocrystallography With Online Database Support, Peter Moeck, Ján Zahornadsky, Boris Dusek

Physics Faculty Publications and Presentations

The crystallographic phase and morphology of many materials change with the crystal size so that new needs arise to determine the crystallography of nanocrystals. Direct space high-resolution phase-contrast transmission electron microscopy (HRTEM) and atomic resolution scanning TEM (STEM) when combined with tools for image-based nanocrystallography in two (2D) and three (3D) dimensions possess the capacity to meet these needs. After a concise discussion of lattice-fringe visibility spheres and maps, this paper discusses lattice-fringe fingerprinting in 2D and tilt protocol applications. On-line database developments at Portland State University (PSU) that support image-based nanocrystallography are also mentioned.
