A Note On The Orientation Of Symmetric Rigid Bodies Sedimenting In A Power-Law Fluid, Ashuwin Vaidya Dec 2005

A Note On The Orientation Of Symmetric Rigid Bodies Sedimenting In A Power-Law Fluid, Ashuwin Vaidya

Department of Mathematics Faculty Scholarship and Creative Works

We study the terminal orientation of symmetric bodies translating in a quiescent liquid modeled by the power-law fluid. We are able to show by invoking the symmetries of the sedimenting body and the Stokes flow field that at small Reynolds numbers, the competition of inertial and shear-thinning (or shear-thickening) contributions to the torque does not cause the tilt angle that is observed in experiments performed on viscoelastic liquids with shear-thinning properties.

Who Is Listening To Local Communities? Connections Between Chicago Region Community-Based Organizations And Regional, State, And National Policy Initiatives, Center For Urban Research And Learning, Philip Nyden, Nathan Benefield, Maureen Hellwig

Center for Urban Research and Learning: Publications and Other Works

As the Chicago metropolitan area continues to grow, a number of plans have been authored by a variety of regional civic organizations. “Regional equity” and “smart growth” have been suggested as organizing principles in some, while economic growth and public revenues have been the focus of others. However, the ongoing role of local community voices in past, present, and future plans is a critical matter. The extent to which future direction of our city and suburbs is informed by local needs partially hinges on the integration of local communities in regional policy debates on both comprehensive plans and specific policy …

A Proposed Design For The Broadband Microwave Distributed Amplifiers, Ali A. Ali, M. S. Abdulwahaab, Azad Raheem Kareem Dec 2005

A Proposed Design For The Broadband Microwave Distributed Amplifiers, Ali A. Ali, M. S. Abdulwahaab, Azad Raheem Kareem

Iraqi Journal of Computers, Communications, Control and Systems Engineering

In this paper, a new method for the design of the broadband RF/microwave amplifiers employing distributed amplification is presented. It proposes to use stages with asymmetric lumped elements (inductances and capacitances) in the gate and drain circuits of the amplifier instead of symmetric elements in order to control the frequency response and to achieve a flat gain over a large bandwidth. The need for impedance matching problems is also solved. Simulation result obtained demonstrates that the new design gives better frequency response as compared to the conventional distributed amplifiers even without optimization

Properties Of Chain Programs Over Difference Constraints, John E. Argentieri Dec 2005

Properties Of Chain Programs Over Difference Constraints, John E. Argentieri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Chain Programming is a restricted form of linear programming in which there exists a total ordering over the program variables. In other words, the constraints x1 ≤ x 2 ≤ ... ≤ xn are either implicitly or explicitly part of the constraint system. At the present juncture, it is not clear whether an arbitrary Chain Program is easier to solve than a linear program, either asymptotically or computationally. This thesis presents a variety of interesting properties pertaining to the case in which a Chain Program is constituted entirely of difference constraints. Deciding the feasibility of a system of difference constraints …

An Ontological View Of The Kingdom Of God In Gutierrez, Segundo, Boff, And Sobrino, Hugo Monroy

Electronic Theses and Dissertations

The great majority of the four hundred and fifty million people in Latin America are poor and oppressed. Presenting the gospel to them as good news is a challenge for any theologian. Theologians' lives are at risk in most places regardless of the ideology they endorse. Jon Sobrino escaped death because he was lecturing out of the country when a military squad came into his home and killed his six companions and the two women who helped them. To serve in a context of poverty and death, theologians need more than church doctrines, creeds, and traditions to sustain them in …

The Application Of Category Theory And Analysis Of Receiver Operating Characteristics To Information Fusion, Steven N. Thorsen

Theses and Dissertations

Multisensor data fusion is presented in a rigorous mathematical format, with definitions consistent with the desires of the data fusion community. A model of event-state fusion is developed and described. Definitions of fusion rules and fusors are introduced, along with the functor categories of which they are objects. Defining fusors and competing fusion rules involves the use of an objective function of the researcher's choice. One such objective function, a functional on families of classification systems, and in particular, receiver operating characteristics (ROCs), is introduced. Its use as an objective function is demonstrated in that the argument that minimizes it …
