From Engineering Electromagnetics To Electromagnetic Engineering: Using Computational Electromagnetics For Synthesis Problems, Anton G. Tijhuis, Martijn C. Van Beurden, Bastiaan P. De Hon, Hubregt J. Visser

Turkish Journal of Electrical Engineering and Computer Sciences

In this paper, a two-stage approach is proposed for using computational electromagnetics in antenna engineering. First, stochastic optimization techniques are used in combination with approximate models. Second, line-search techniques are combined with full-wave modeling. For the first stage, we show an illustrative example. The second stage is considered in detail; both the acceleration of the underlying field computations and the implementation of the optimization are discussed.

A Summary Of Recent Developments On Metamaterial-Based And Metamaterial-Inspired Efficient Electrically Small Antennas, Aycan Erentok, Richard W. Ziolkowski

Turkish Journal of Electrical Engineering and Computer Sciences

This paper summarizes our recent research efforts to realize efficient electrically small antenna (EESA) systems based on ideal analytical and numerical metamaterial-based antenna systems, and physically realized metamaterial-inspired antenna designs. Our theoretical and numerical studies of the radiation and resonance behaviors of the proposed metamaterial-based EESA systems, as well as our efforts to conceptualize structures which might be used to build them, have led to the discovery of several realizable metamaterial-inspired EESA systems. The measurement results confirm the numerical performance predictions.

When Is The Commutant Of A Bol Loop A Subloop?, J.D. Phillips

Journal Articles

A left Bol loop is a loop satisfying x(y(xz)) = (x(yx))z. The commutant of a loop is the set of all elements which commute with all elements of the loop. In a finite Bol loop of odd order or of order 2k, k odd, the commutant is a subloop. We investigate conditions under which the commutant of a Bol loop is not a subloop. In a finite Bol loop of order relatively prime to 3, the commutant generates an abelian group of order dividing the order of the loop. This generalizes a well-known result for Moufang loops. After describing all …

F-Quasigroups And Generalized Modules, J.D. Phillips

Journal Articles

In [3], we showed that every F-quasigroup is linear over a special kind of Moufang loop called an NK-loop. Here we extend this relationship by showing an equivalence between the class of (pointed) F-quasigroups and the class corresponding to a certain notion of generalized module (with noncommutative, nonassociative addition) for an associative ring.

Best P-Simultaneous Approximation In Some Metric Space, Mona Khandaqji, Wasfi Shatanawi

Turkish Journal of Mathematics

Let X be a Banach space, (I,\mu) be a finite measure space, and \Phi be an increasing subadditive continuous function on [0,+\infty) with \Phi(0)=0. In the present paper, we discuss the best p-simultaneous approximation of L^\Phi(I,G) in L^\Phi(I,X) where G is a closed subspace of X.

Some Characterizations Of Rectifying Curves In The Euclidean Space E^4, Kazim İlarslan, Emilija Nesovic

Turkish Journal of Mathematics

In this paper, we define a rectifying curve in the Euclidean 4-space as a curve whose position vector always lies in orthogonal complement N^{\perp} of its principal normal vector field N. In particular, we study the rectifying curves in E^4 and characterize such curves in terms of their curvature functions.

Nonexistence Of Stable Exponentially Harmonic Maps From Or Into Compact Convex Hypersurfaces In R^{M+1}, Jiancheng Liu

Turkish Journal of Mathematics

In this paper, we study the nonexistence problems for stable exponentially harmonic map into or from compact convex hypersurface M^m \subset R^{m+1}, and show that every nonconstant exponentially harmonic map f, between M^m and any compact Riemannian manifold, is unstable if (4) holds.

Primary Finitely Compactly Packed Modules And S-Avoidance Theorem For Modules, Arwa Eid Ashour

Turkish Journal of Mathematics

In this paper we introduce the concept of primary finitely compactly packed modules, which generalizes the concept of primary compactly packed modules. We first find the conditions that make the primary finitely compactly packed modules primary compactly packed. Also, several results on the primary finitely compactly packed modules are proved. In addition, the necessary and sufficient conditions for an R-module M to be primary finitely compactly packed are investigated. Finally, we introduce the S-Avoidance Theorem for modules.

True Will Vs. Conscious Will: An Exploration Of Aleister Crowley's Concepts Of True Will And Conscious Will And Its Possible Applications To A Midsummer Nights Dream, Marison, And Wicked, John Payne

Electronic Theses and Dissertations

In our lives we will have to make hundreds upon thousands of choices. The effects of these choices will follow us with varying intervals; some effects may be brief while others may literally last a lifetime. In these moments that we are forced to chose, it ultimately comes down to two options, what we should do, and what we want to do. Essentially, it is a choice between the head and the heart. Playwrights depend on these moments of choice, for it is the basis of almost all plays. At some point, the protagonist must make a choice, even if …

Emulating The Swedes: An Exploration Of The Developing Trends In Swedish Theatre For Young Audiences, Amanda Wolgast

Electronic Theses and Dissertations

As a practitioner in the field of Theatre for Young Audiences (TYA), I have always been drawn to looking at literature and productions that challenge my preconceptions of what constitutes good theatre for youth. I enjoy the bold and innovative, versus the cute and playful. My training and education in this developing branch of theatre has undoubtedly exposed me to the many accomplishments of the American TYA system, but quite often - through attending conferences, as well as participating in class discussions - I find that many debates/conversations center around what more we need to do in this field or …

The Identification Of Ignitable Liquids In The Presence Of Pyrolysis Products: Generation Of A Pyrolysis Product Database, Joseph Castelbuono

Electronic Theses and Dissertations

The fire debris analyst is often faced with the complex problem of identifying ignitable liquid residues in the presence of products produced from pyrolysis and incomplete combustion of common building and furnishing materials. The purpose of this research is to investigate a modified destructive distillation methodology provided by the Florida Bureau of Forensic Fire and Explosive Analysis to produce interfering product chromatographic patterns similar to those observed in fire debris case work. The volatile products generated during heating of substrate materials are extracted from the fire debris by passive headspace adsorption and subsequently analyzed by GC-MS. Low density polyethylene (LDPE) …

Multi-Material Contact For Computational Structural Mechanics, Kenneth Cline Walls

All ETDs from UAB

Multi-material Eulerian formulations in computational structural mechanics are traditionally approached using mixed-element thermodynamic or constitutive models. These traditional approaches replace contacting materials in an element with an equivalent, single material. However, this approximation often has little basis in the actual physics taking place at the contacting boundary. This work presents a significant departure from traditional Eulerian contact models by solving the conservation equations in each material separately and then imposing inequality constraints associated with contact to the solutions for each material with the appropriate traction integrals included. The advantages of this method are demonstrated with several computational examples. This work …

Controlled Deposition Of Magnetic Molecules And Nanoparticles On Atomically Flat Gold Surfaces, Md. Firoze Haque

Electronic Theses and Dissertations

In this thesis I am presenting a detailed study to optimize the deposition of magnetic molecules and gold nanoparticles in atomically flat surfaces by self-assembling them from solution. Epitaxially grown and atomically flat gold surface on mica is used as substrate for this study. These surfaces have roughness of the order one tenth of a nanometer and are perfect to image molecules and nanoparticles in the 1-10 nanometers range. The purpose of these studies is to find the suitable parameters and conditions necessary to deposit a monolayer of nano-substance on chips containing gold nanowires which will eventually be used to …

Searching For The Majority: Algorithms Of Voluntary Control, Jin Fan, Kevin G. Guise, Xun Liu, Hongbin Wang

Faculty, Staff and Student Publications

Voluntary control of information processing is crucial to allocate resources and prioritize the processes that are most important under a given situation; the algorithms underlying such control, however, are often not clear. We investigated possible algorithms of control for the performance of the majority function, in which participants searched for and identified one of two alternative categories (left or right pointing arrows) as composing the majority in each stimulus set. We manipulated the amount (set size of 1, 3, and 5) and content (ratio of left and right pointing arrows within a set) of the inputs to test competing hypotheses …

Security Design That Addresses Agency Conflicts And Information Asymmetry, Manish Tewari

Electronic Theses and Dissertations

This study focuses on the role of structured derivative securities to meet diverse corporate financing objectives in the light of agency theory and asymmetric information. The focus is on the nonconvertible callable-puttable fixed-coupon bonds. The primary objective is to discern the marginal role of the put and put-deferred features in addressing the agency issues and asymmetric information. A sample of (159) securities issued over the period (1977-2005) are examined using Merton's (1974) structural contingent claims valuation model. The put option as well as the deferred put option incorporated in these securities is found to mitigate the asset substitution issue. It …

Spousal Support Advisory Guidelines, Rollie Thompson, Carol Rogerson

Reports & Public Policy Documents

In 2001 the federal Department of Justice identified the need for a project to explore the possibility of developing some form of advisory spousal support guidelines. The aim of the project was to bring more certainty and predictability to the determination of spousal support under the Divorce Act.1 The project was a response to growing concerns expressed by lawyers, judges, mediators and the public about the lack of certainty and predictability in the current law of spousal support, creating daily dilemmas in advising clients, and negotiating, litigating or—in the case of judges—deciding spousal support issues. We were retained to direct …

Testing Xuml: A Study Of Implementing And Testing Model Driven Architecture, Dylan O. Flaherty

Graduate Student Theses, Dissertations, & Professional Papers

Model Driven Architecture (MDA) is a relatively new and completely different approach to developing software in which diagrams and formal specifications are written and then translated into executable programs. Development using this approach takes longer than using traditional software engineering approaches, but results in products that more correctly meet user requirements and take less maintenance effort. While there is considerable information available regarding development using MDA, the implications for testing have not been fully explored or measured. In order to investigate this facet of MDA, a traditional C++ program which had previously been tested was rebuilt as an MDA model. …

The Contribution Of Spawning Pacific-Salmon To Nitrogen Fertility And Vegetation Nutrition During Riparian Primary Succession On An Expansive Floodplain Of A Large River, Michael Roger Morris

Graduate Student Theses, Dissertations, & Professional Papers

Floodplain vegetation communities are mosaics of succession stages caused by erosion/redeposition as river channels migrate throughout their floodplains. Typically, plants colonizing alluvial deposits are severely N-limited, but N accumulates during succession, and this process determines long term fertility. The Kol River (Kamchatka, RU), received large annual N-subsidies from salmon and we sought to determine how salmon-N contributed to fertility during succession.

We constructed a vegetation chronosequence model and made N-fertility measurements within replicate succession stages before, during and after salmon runs. Natural abundance of 15N was used as a tracer of salmon-N.

We found that new alluvial deposits were N-poor, …

Educating Citizens: Have We Kept The Founders’ Ideals For Higher Education?, Hans Zieger

Pepperdine Policy Review

Engraved above the colonnade of the Angell Building at the University of Michigan are the words of the Northwest Ordinance of 1787: “Religion, morality, and knowledge, being necessary to good government and the happiness of mankind, schools and the means of education shall forever be encouraged” (Northwest Ordinance). The irony of this inscription is that religion and traditional morality are not highly regarded at the University of Michigan. The University of Michigan was one of the major outposts in the campus wars of the 1960s, the legacy of which is a campus culture of multiculturalism, sexual obsession, and political correctness. …

On Communication, John Greenman

Michigan Law Review

Everybody knows that communication is important, but nobody knows how to define it. The best scholars refer to it. Free-speech law protects it. But no one-no scholar or judge-has successfully captured it. Few have even tried. This is the first article to define communication under the law. In it, I explain why some activities-music, abstract painting, and parading-are considered communicative under the First Amendment, while others-sex, drugs, and subliminal advertising-are not. I argue that the existing theories of communication, which hold that communicative behaviors are expressive or convey ideas, fail to explain what is going on in free-speech cases. Instead, …

Due Process Traditionalism, Cass R. Sunstein

Michigan Law Review

In important cases, the Supreme Court has limited the scope of "substantive due process" by reference to tradition, but it has yet to explain why it has done so. Due process traditionalism might be defended in several distinctive ways. The most ambitious defense draws on a set of ideas associated with Edmund Burke and Friedrich Hayek, who suggested that traditions have special credentials by virtue of their acceptance by many minds. But this defense runs into three problems. Those who have participated in a tradition may not have accepted any relevant proposition; they might suffer from a systematic bias; and …
