A Snapshot Algorithm For Linear Feedback Flow Control Design, Benjamin T. Dickinson, Belinda A. Batten, John R. Singler

Mathematics and Statistics Faculty Research & Creative Works

The control of fluid flows has many applications. For micro air vehicles, integrated flow control designs could enhance flight stability by mitigating the effect of destabilizing air flows in their low Reynolds number regimes. However, computing model based feedback control designs can be challenging due to high dimensional discretized flow models. In this work, we investigate the use of a snapshot algorithm proposed in Ref. 1 to approximate the feedback gain operator for a linear incompressible unsteady flow problem on a bounded domain. The main component of the algorithm is obtaining solution snapshots of certain linear flow problems. Numerical results …

Weak Sharp Minima On Riemannian Manifolds, Chong Li, Boris S. Mordukhovich, Jinhua Wang, Jen-Chih Yao

Mathematics Research Reports

This is the first paper dealing with the study of weak sharp minima for constrained optimization problems on Riemannian manifolds, which are important in many applications. We consider the notions of local weak sharp minima, boundedly weak sharp minima, and global weak sharp minima for such problems and obtain their complete characterizations in the case of convex problems on finite-dimensional Riemannian manifolds and their Hadamard counterparts. A number of the results obtained in this paper are also new for the case of conventional problems in linear spaces. Our methods involve appropriate tools of variational analysis and generalized differentiation on Riemannian …

A Radial Basis Function Method For The Shallow Water Equations On A Sphere, Natasha Flyer, Grady Wright

Mathematics Faculty Publications and Presentations

The paper derives the first known numerical shallow water model on the sphere using radial basis function (RBF) spatial discretisation, a novel numerical methodology that does not require any grid or mesh. In order to perform a study with regard to its spatial and temporal errors, two nonlinear test cases with known analytical solutions are considered. The first is global steady-state flow with a compactly supported velocity field while the second is unsteady flow where features in the flow must be kept intact without dis- persion. This behavior is achieved by introducing forcing terms in the shallow water equations. Error …

Finding Cost-Effective Methods For Language Access Services Administration At New York City Children's Services, Kerry Cook

MPA Capstone Projects 2006 - 2015

New York City Children's Services (CS) serves an increasing populations of persons with limited English language proficiency (LEP). Federal and local laws mandate that these persons are provided with meaningful language access services. This analysis attempts to find the most cost-effective strategy for CS' Division of Child Protection (DCP) to provide interpretation services to LEP persons involved in DCP cases of child abuse and neglect. The study first identifies alternative strategies for providing these services, and then qualifies the cost of the current methods and alternative methods. A framework of transaction cost economic theory guides the cost analysis process. Next, …

The proofs involve a variety of techniques, including series-series identities, Bailey pairs, a theorem of Watson on basic hypergeometric series, generating functions and miscellaneous methods.

Counting On Chebyshev Polynomials, Arthur T. Benjamin, Daniel Walton '07

All HMC Faculty Publications and Research

Chebyshev polynomials have several elegant combinatorial interpretations. Specificially, the Chebyshev polynomials of the first kind are defined by T₀(x) = 1, T₁(x) = x, and T_n(x) = 2x T_n-1(x) - T_n-2(x). Chebyshev polynomials of the second kind U_n(x) are defined the same way, except U₁(x) = 2x. T_n and U_n are shown to count tilings of length n strips with squares and dominoes, where the tiles are given weights and sometimes color. Using these interpretations, many identities satisfied by Chebyshev polynomials can be given …

Math Island At Brewer Elementary School: A Learner-Centered Model For Education, Vikki K. Collins, H. Marguerite Yates

Georgia Educational Researcher

This paper examines a learner-centered model for the teaching of elementary mathematics established at an urban Georgia school that serves a highly mobile, diverse population of approximately 475 students. The school was on its state’s list of schools needing improvement because students continued to perform poorly on standardized tests. Math Island, a support center for students designed to facilitate the conceptual understanding of mathematics, was created, and professional development programs were implemented to assist teachers in developing their pedagogical and content expertise in the teaching of mathematics. The school made substantial progress after these initiatives were employed and was removed …

Computational Simulation Of Strain Localization: From Theory To Implementation, Shouxin Wu

Doctoral Dissertations

Strain localization in the form of shear bands or slip surfaces has widely been observed in most engineering materials, such as metals, concrete, rocks, and soils. Concurrent with the appearance of localized deformation is the loss of overall load-carrying capacity of the material body. Because the deformation localization is an important precursor of material failure, computational modeling of the onset and growth of the localization is indispensable for the understanding of the complete mechanical response and post-peak behavior of materials and structures. Simulation results can also be used to judge the failure mechanisms of materials and structures so that the …

Numerical Simulations Of Snake Dissipative Solitons In Complex Cubic-Quintic Ginzburg-Landau Equation, S.C. Mancas, Harihar Khanal

Publications

Numerical simulations of the complex cubic-quintic Ginzburg-Landau equation (CCQGLE), a canonical equation governing the weakly nonlinear behavior of dissipative systems in a wide variety of disciplines, reveal five entirely novel classes of pulse or solitary waves solutions, viz. pulsating, creeping, snaking, erupting, and chaotical solitons. Here, we develop a theoretical framework for analyzing the full spatio-temporal structure of one class of dissipative solution (snaking soliton) of the CCQGLE using the variational approximation technique and the dynamical systems theory. The qualitative behavior of the snaking soliton is investigated using the numerical simulations of (a) the full nonlinear complex partial differential equation …

Large-Scale Assembly Of Periodic Nanostructures With Metastable Square Lattices, Chih-Hung Sun, Wei-Lun Min, Nicholas C. Linn, Peng Jiang, Bin Jiang

Mathematics and Statistics Faculty Publications and Presentations

This article reports a simple and scalable spin-coating technique for assembling non-close-packed colloidal crystals with metastable square lattices over wafer-scale areas. The authors observe the alternate formation of hexagonal and square diffraction patterns when the thickness of the colloidal crystals is gradually reduced during spin coating. No prepatterned templates are needed to induce the formation of the resulting metastable crystals with square arrangement. This bottom-up technology also enables the large-scale production of a variety of squarely ordered nanostructures that are consistent with the industry-standard rectilinear coordinate system for simplified addressing and circuit interconnection. Broadband moth-eye antireflection gratings with square lattices …

Basic Math Skills: Can High School Students Do The Math?, Samantha Sebastian

Leah A. Nillas

This article examined high school students’ basic mathematics skills. 126 Students participated in a study that lasted ten weeks in which a pretest and post-test were taken. In between the tests, students took weekly quizzes to refresh and relearn the following basic mathematics skills: adding, subtracting, multiplying, and dividing whole numbers, decimals, and fractions; proportions; conversion between percents, decimals, and fractions; and order of operations. The scores of the pretest and post-test were analyzed to see if improvements were made. Scores were compared by gender and grade level. The study showed an overall improvement on students’ ability to do basic …

Breaking Language Barriers: Connections Between Foreign Language And English Language Arts, Lauren Booth, '09

Leah A. Nillas

The purpose of this study was to investigate the relationships between foreign language and English language arts. In previous literature, foreign language has been shown to positively affect students' performance in other subject areas as well as developing their cognitive abilities. When I thought about my own teaching experiences, I made direct connections between foreign language and English language arts in terms of vocabulary acquisition and grammar. Through interviews I found that other teachers are also aware of those connections and deliberately use them to enhance their instruction and defend the study of a foreign language. Upon investigating foreign language …

The Impact Of Extracurricular Activities On High School Students’ Academic Success, Nicholas Cooprider

Leah A. Nillas

“Although we cannot conclude from the data that extracurricular activities alone caused these improvements, we can say with virtual certainty that when we help a student move from no participation in extracurricular activities to engagement in three or four such activities, it does not harm academic performance” (Reeves, 2008, p.2). Previous research concluded that participation in extracurricular activities does correlate to academic achievement in the classroom. This research examined how students perceived their involvement in extracurricular activities affected their academic performance. Surveys were distributed to a local, rural high school and students were asked to document the amount of time …

Communication Across Random Landings, Kerron Joseph, Jay Walbran

Undergraduate Research Conference

The idea to do this project began with a simple question: Suppose that people carrying communication radios parachute out of a plane, if each device has a certain range, what is the probability that once everyone lands they will be able to communicate. To study this problem I assumed that the spot where each individual lands is normally distributed.

We discuss the different ways the communication radios can work. In particular we examine the situation where all the radios have to be within a certain radius r to operate correctly and the situation where the radios work on a relay …
