Resolutions And Tor Algebra Structures For Trivariate Monomial Ideals, Jared Lafayette Painter Jan 2012

Resolutions And Tor Algebra Structures For Trivariate Monomial Ideals, Jared Lafayette Painter

Mathematics Dissertations - Archive

In this manuscript we explore properties of minimal free resolutions and their relationship to the Tor-algebra structure for trivariate monomial ideals. We begin with an in-depth analysis of minimal free resolutions of S = R / I, where R = k[x; y; z] is a polynomial ring over a field k, and I is a monomial ideal that is primary to the homogeneous maximal ideal m of R. We will de ne a special form of the minimal free resolution of S, and then determine when we get nonzero elements from I as entries in the matrices of the resolution. …

High Order Dns For Late Flow Transition, Ping Lu Jan 2012

High Order Dns For Late Flow Transition, Ping Lu

Mathematics Dissertations - Archive

In this report, a new high order scheme for boundary points is introduced when calculating the derivative of smooth functions by Compact Scheme. The primitive function reconstruction method of ENO schemes is applied to obtain the conservative form of the Compact Scheme. Meanwhile, modified compact scheme is developed by using an effective shock detector to block upwinding compact scheme to cross the shock, a control function, and an adaptive scheme which uses some WENO flux near the shock. The new scheme makes the original upwinding compact scheme able to capture the shock sharper than WENO and, more important, keep high …

A Doubling Technique For The Power Method Transformations, Mohan Pant, Todd C. Headrick Jan 2012

A Doubling Technique For The Power Method Transformations, Mohan Pant, Todd C. Headrick

Curriculum and Instruction Faculty Publications - Archive

Power method polynomials are used for simulating non-normal distributions with specified product moments or L-moments. The power method is capable of producing distributions with extreme values of skew (L-skew) and kurtosis (L-kurtosis). However, these distributions can be extremely peaked and thus not representative of real-world data. To obviate this problem, two families of distributions are introduced based on a doubling technique with symmetric standard normal and logistic power method distributions. The primary focus of the methodology is in the context of L-moment theory. As such, L-moment based systems of equations are derived for simulating univariate and multivariate non-normal distributions with …

No Utopia Is An Island: The Ecosystem Of Utopias In Paul Mcauley's Quiet War Saga, Kerri Beauchesne Jan 2012

No Utopia Is An Island: The Ecosystem Of Utopias In Paul Mcauley's Quiet War Saga, Kerri Beauchesne

English Theses - Archive

In this thesis, I argue that a new, ambitious variety of literary utopia, which I call an ecosystem utopia, has developed over the past forty years, chiefly in science fiction and fantasy. My primary examples are Paul McAuley's The Quiet War and Gardens of the Sun. An ecosystem utopia portrays a dynamic network of societies in a text's fictional time and space. Like a traditional utopia, it explores the structure and functioning of individual utopias, and like the critical utopia, their flaws and ambiguities. Sociopolitically complex, it explores threads of influence, alliance, conflict, exploitation, and dominance within and between multiple …

Networked Authorship: A Community Of Creators In Born-Digital Literature, Tricia Jost Dupew

English Theses - Archive

Authorship of born-digital literature exists in a state referent to but decidedly apart from authorship of more traditional printed texts. Ranging far from the idea that the author exists in a state of solitary genius, authorship in born-digital literature is a collective endeavor which both reacts to and anticipates an ongoing cultural shift from material goods produced in an industrial setting to immaterial goods produced in the networked environment of the cultural collective. By examining the creation of born-digital texts, the placement of the reader within the textual and multimedia experience itself, and the influence of the intelligent machine in …

Adaptive Dynamic Programming For High-Dimensional, Multicollinear State Spaces, Bancha Ariyajunya

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive

Dynamic programming (DP) is a mathematical programming method for optimizing a system changing over time and has been used to solve multi-stage optimization problems in manufacturing systems, environmental engineering, and many other fields. Exact solutions are only possible for small problems or under very limiting restrictions, but computationally practical approximate DP methods now exist. Most continuous-state problems require discretization of the state space. A design and analysis of computer experiments (DACE) approach for approximate DP uses experimental design and statistical modeling to approximate the value function in continuous-state problems. However, ideal experimental designs are orthogonal, and when the state variables …

Cnt Reinforced Epoxy Foamed And Electrospun Nano-Fiber Interlayer Systems For Manufacturing Lighter And Stronger Featherweight Composites, Vasileios M. Drakonakis

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive

Multiple works have been performed in improving carbon fiber reinforced polymer (CFRP) composites especially in terms of strength so delamination, which is the major defect in laminated composites, is prevented. Nevertheless, there is not much focus on improving conventional CFRP systems in terms of weight especially when these are used in primary structures. This work questions whether lighter and at the same time stronger CFRP composites can be manufactured in order to replace conventional CFRP systems in major applications. Under this perspective, this study demonstrates that inducing controlled porosity may offer a systemic approach for manufacturing light weight carbon fiber …

The Private Sectors Pivotal Role In Combating Human Trafficking, Jonathan Todres Jan 2012

The Private Sectors Pivotal Role In Combating Human Trafficking, Jonathan Todres

Faculty Publications By Year

Human trafficking is big business, with industry estimates running in the billions of dollars annually. Much of that profit accrues to traffickers, illegal profiteers, and organized crime groups. However, the private sector also reaps economic benefits, directly and indirectly, from human trafficking. Despite these economic realities, the dominant approach to combating human trafficking has been to rely almost exclusively on governments and social services organizations to do the job. Little has been asked of the private sector. Two important bills - one adopted by the State of California and the other introduced in the U.S. House of Representatives - might …
