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

Bcc-To-Hcp Transformation Pathways For Iron Versus Hydrostatic Pressure: Coupled Shuffle And Shear Modes, J. B. Liu, Duane D. Johnson
Bcc-To-Hcp Transformation Pathways For Iron Versus Hydrostatic Pressure: Coupled Shuffle And Shear Modes, J. B. Liu, Duane D. Johnson
Duane D. Johnson
Using density-functional theory, we calculate the potential-energy surface (PES), minimum-energy pathway (MEP), and transition state (TS) versus hydrostatic pressure σhyd for the reconstructive transformation in Fe from body-centered cubic (bcc) to hexagonal closed-packed (hcp). At fixed σhyd, the PES is described by coupled shear (ϵ) and shuffle (η) modes and is determined from structurally minimized hcp-bcc energy differences at a set of (η,ϵ). We fit the PES using symmetry-adapted polynomials, permitting the MEP to be found analytically. The MEP is continuous and fully explains the transformation and its associated magnetization and volume discontinuity at TS. We show that σhyd (while …

Riesz Bases Of Root Vectors Of Indefinite Sturm-Liouville Problems With Eigenparameter Dependent Boundary Conditions. Ii, Paul Binding, Branko Ćurgus
Mathematics Faculty Publications
We consider a regular indefinite Sturm-Liouville problem with two self-adjoint boundary conditions affinely dependent on the eigenparameter. We give sufficient conditions under which the root vectors of this Sturm-Liouville problem can be selected to form a Riesz basis of a corresponding weighted Hilbert space.

We Owe It To The Earth: The Importance Of Environmentally-Friendly Lifestyle Changes During The Transitional College Years, Jessica E. Clark
Honors Projects in Science and Technology
This paper aims to explain and justify my choice of film as the medium employed to persuade my audience of the need for environmentally-friendly lifestyle changes to be made by individuals. In order to effectively stimulate action by college students, the target audience, film was used to communicate the necessity of developing green habits. During these years students in higher education develop intellectually and mature into adults. It is a prime time to learn simple green lifestyle changes and translate them into their daily behavioral repertoire. To begin my project I researched current information about the state of our environment, …

The Pyro Toolkit For Ai And Robotics, Doug Blank, Deepak Kumar, Lisa Meeden, Holly Yanco
The Pyro Toolkit For Ai And Robotics, Doug Blank, Deepak Kumar, Lisa Meeden, Holly Yanco
Computer Science Faculty Research and Scholarship
This article introduces Pyro, an open-source Python robotics toolkit for exploring topics in AI and robotics. We present key abstractions that al- low Pyro controllers to run unchanged on a variety of real and simulated robots. We demonstrate Py- ro’s use in a set of curricular modules. We then de- scribe how Pyro can provide a smooth transition for the student from symbolic agents to real-world robots, which significantly reduces the cost of learning to use robots. Finally we show how Pyro has been successfully integrated into existing AI and robotics courses.

Mine, Yours Or Ours?: The Role Of Local Identity In United Way System Redesign, Elizabeth Claire Monaco
MPA Capstone Projects 2006 - 2015
For-profit and non-profit entities alike are facing the challenges of recruiting and retaining effective leadership, gathering sufficient and competitive capital and achieving long-term credibility as they struggle to assert their legitimacy and ensure sustainability in an ever changing world. These challenges have forced many organizations to consider different business models of operations, including opportunities to partner with others in their sector. There exists a growing list of non-profit federations that are considering and pursuing complete system redesign through the strategic restructuring of their affiliates in response to factors such as competition for resources, environmental and institutional pressures and the effects …

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, …

Kinetic Studies On Enzyme-Catalyzed Reactions: Oxidation Of Glucose, Decomposition Of Hydrogen Peroxide And Their Combination, Zhimin Tao, Ryan A. Raffel, Abdul-Kader Souid, Jerry Goodisman
Chemistry - All Scholarship
The kinetics of the glucose oxidase-catalyzed reaction of glucose with O2, which produces gluconic acid and hydrogen peroxide, and the catalase-assisted breakdown of hydrogen peroxide to generate oxygen, have been measured via the rate of O2 depletion or production. The O2 concentrations in air-saturated phosphate-buffered salt solutions were monitored by measuring the decay of phosphorescence from a Pd phosphor in solution; the decay rate was obtained by fitting the tail of the phosphorescence intensity profile to an exponential. For glucose oxidation in the presence of glucose oxidase, the rate constant determined for the rate-limiting step was k = (3.0 ± …

Physics
According to Noether’s theorem1, for every symmetry in nature there is a corresponding conservation law. For example, invariance with respect to spatial translation corresponds to conservation of momentum. In another well-known example, invariance with respect to rotation of the electron’s spin, or SU(2) symmetry, leads to conservation of spin polarization. For electrons in a solid, this symmetry is ordinarily broken by spin–orbit coupling, allowing spin angular momentum to flow to orbital angular momentum. However, it has recently been predicted that SU(2) can be achieved in a two-dimensional electron gas, despite the presence of spin–orbit coupling2. The …

The Design And Synthesis Of Farnesyl "Tail" Analogues Incorporating Aromatic Rings: A Comparison Of Wittig And Grignard Reaction Sequences, Mark F. Mechelke, Lisa Motschke, Todd Nichols, Sarah Albrecht
Chemistry Faculty Publications
Mutant RAS proteins have been linked to over 30 of all human cancers. It has been shown that mutant RAS proteins that cannot be farnesylated do not induce malignant transformation. Therefore, farnesyl protein transferase (FPTase) inhibitors have become attractive targets as potential chemotherapeutic agents. Two farnesyl "tail" analogues have been prepared that incorporate aromatic rings. One of the compounds, trans-9-phenyl-8-nonen-1-ol, could only be prepared pure using a Grignard reaction sequence. This sequence is compared to the initially attempted Wittig reaction sequence that results in an inseparable mixture of cis/trans isomers. It is anticipated thatwhen coupled with poal diphosphate "head" …
