On Construction Of The Smallest One-Sided Confidence Interval For The Difference Of Two Proportions, 2010 Wright State University - Main Campus

#### On Construction Of The Smallest One-Sided Confidence Interval For The Difference Of Two Proportions, Weizhen Wang

*Mathematics and Statistics Faculty Publications*

For my class of one-sided 1 - α confidence intervals with a certain monotonicity ordering on the random confidence limit, the smallest interval, in the sense of the set inclusion for the difference of two proportions of two independent binomial random variables, is constructed based on a direct analysis of coverage probability function. A special ordering on the confidence limit is developed and the corresponding smallest confidence interval is derived. This interval is then applied to identify the minimum effective dose (MED) for binary data in dose-response studies, and a multiple test procedure that controls the familywise error rate at level ...

Applying Metric Regularity To Compute Condition Measure Of Smoothing Algorithm For Matrix Games, 2010 Wayne State University

#### Applying Metric Regularity To Compute Condition Measure Of Smoothing Algorithm For Matrix Games, Boris S. Mordukhovich, Javier Peña, Vera Roshchina

*Mathematics Research Reports*

Abstract. We develop an approach of variational analysis and generalized differentiation to conditioning issues for two-person zero-sum matrix games. Our major results establish precise relationships between a certain condition measure of the smoothing first-order algorithm proposed in (4] and the exact bound of metric regularity for an associated set-valued mapping. In this way we compute the aforementioned condition measure in terms of the initial matrix game data.

Measuring Balkanization In Wikipedia, 2010 Macalester College

#### Measuring Balkanization In Wikipedia, Colin Welch

*Mathematics, Statistics, and Computer Science Honors Projects*

Modern society has become increasingly balkanized, or ideologically polarized and socially fragmented. Political parties interact with each other over divisive issues by using polarizing rhetoric. Internet users create small, opinionated communities like dKosapedia and Conservapedia, Wikipedia-like websites written from positions of left-leaning and right-leaning bias. Even Wikipedia may not be immune to balkanization. As a free encyclopedia written by users from an unbiased point of view, it is in the interest of the general public to keep Wikipedia as free of balkanization and polarization as possible. If Wikipedia authors are free to express their conflicting points of view, the quality ...

High Order Finite Elements For Lagrangian Computational Fluid Dynamics, 2010 California Polytechnic State University - San Luis Obispo

#### High Order Finite Elements For Lagrangian Computational Fluid Dynamics, Truman Everett Ellis

*Master's Theses and Project Reports*

A general finite element method is presented to solve the Euler equations in a Lagrangian reference frame. This FEM framework allows for separate arbitrarily high order representation of kinematic and thermodynamic variables. An accompanying hydrodynamics code written in Matlab is presented as a test-bed to experiment with various basis function choices. A wide range of basis function pairs are postulated and a few choices are developed further, including the bi-quadratic Q2-Q1d and Q2-Q2d elements. These are compared with a corresponding pair of low order bi-linear elements, traditional Q1-Q0 and sub-zonal pressure Q1-Q1d. Several test problems are considered including static convergence ...

Parallel Efficiency-Based Adaptive Local Refinement, 2010 University of Colorado Boulder

#### Parallel Efficiency-Based Adaptive Local Refinement, Lei Tang

*Applied Mathematics Graduate Theses & Dissertations*

New adaptive local refinement (ALR) strategies are developed, the goal of which is to reach a given error tolerance with the least amount of computational cost. This strategy is especially attractive in the setting of a first-order system least-squares (FOSLS) finite element formulation in conjunction with algebraic multigrid (AMG) methods in the context of nested iteration (NI). To accomplish this, the refinement decisions are determined based on minimizing the predicted `accuracy-per-computational-cost' efficiency (ACE). The nested iteration approach produces a sequence of refinement levels in which the error is equally distributed across elements on a relatively coarse grid. Once the solution ...

#### Striving For The Edge In Investing: A Statistical Analysis On The Current Asset To Market Capitalization Ratio, Adrian Conley

*Mathematics, Engineering and Computer Science Undergraduate Theses*

A new ratio pertinent to the energy sector, as defined by Google Finance, the current asset to market capitalization ratio, was created and analyzed to determine its utility as an investment aid, using z statistics. Fifty-five companies with a current asset to market capitalization ratio of 0.3 or higher were chosen along with seventy-eight randomly selected companies within the same sector. The fifty-five companies had an average year-over-year return of 54.49% with a standard deviation of 106.72%, while the randomly selected companies returned a year-over-year 18.42% with a standard deviation of 65.2%. The null hypothesis ...

Verification Of A Support Vector Machine Model For Predicting Proteotypic Peptides, 2010 Carroll College, Helena, MT

#### Verification Of A Support Vector Machine Model For Predicting Proteotypic Peptides, Jessica Forbes

*Mathematics, Engineering and Computer Science Undergraduate Theses*

The current method to match mass spectra from tandem mass spectrometry (MS) to a peptide sequence requires searching a large database of all possible peptides encoded by an organism. However, only a subset of these possible peptides is consistently and repeatedly identified by MS (proteotypic peptides). Matching spectra to this smaller, proteotypic peptide search space increases computational efficiency and improves accuracy of the peptide identification, hence increasing the confidence that a protein has been accurately identified. Currently, it is labor-intensive to build a proteotypic peptide database of experimentally observed peptides! thus computationally deriving such a database is desirable. Webb-Robertson et ...

*Applied Mathematics Graduate Theses & Dissertations*

Digital microfluidics is a rapidly growing field wherein droplets are manipulated for use in small-scale applications such as variable focus lenses, display technology, fiber optics, and lab-on-a-chip devices. There has been considerable interest in digital microfluidics and the various methods for liquid actuation by thermal, chemical, and electrical means, where each of the actuation methods make use of the favorable scaling relationship of surface tension forces at the micro scale.

Another increasingly important field is addressing the ever growing need for improved heat transfer techniques in the next generation of electronic devices. As device size decreases and device efficiency increases ...

Parametric Lp Analysis, 2010 Rose-Hulman Institute of Technology

#### Parametric Lp Analysis, Allen Holder

*Mathematical Sciences Technical Reports (MSTR)*

Parametric linear programming is the study of how optimal properties depend on data parametrizations. The study is nearly as old as the field of linear programming itself, and it is important since it highlights how a problem changes as what is often estimated data varies. We present what is a modern perspective on the classical analysis of the objective value's response to parametrizations in the right-hand side and cost vector. We also mention a few applications and provide citations for further study

*Jonathan P. Sorenson*

We discuss a method for computing Σ �≤� 1/�, using time about �2/3 and space about �1/3. It is based on the Meissel-Lehmer algorithm for computing the prime-counting function �(�), which was adapted and improved by Lagarias, Miller, and Odlyzko. We used this algorithm to determine the first point at which the prime harmonic sum first crosses.
