Fixed Points Of Abelian Actions On S2, John Franks, Michael Handel, Kamlesh Parwani Oct 2007

Fixed Points Of Abelian Actions On S2, John Franks, Michael Handel, Kamlesh Parwani

Kamlesh Parwani

We prove that if $F$ is a finitely generated abelian group of orientation preserving $C^1$ diffeomorphisms of $R^2$ which leaves invariant a compact set then there is a common fixed point for all elements of $F.$ We also show that if $F$ is any abelian subgroup of orientation preserving $C^1$ diffeomorphisms of $S^2$ then there is a common fixed point for all elements of a subgroup of $F$ with index at most two.

We prove that if $\F$ is an abelian group of $C^1$ diffeomorphisms isotopic to the identity of a closed surface $S$ of genus at least two then there is a common fixed point for all elements of $\F.$

Graphics With Pgf And Tikz, Andrew Mertz, William Slough Jan 2007

Graphics With Pgf And Tikz, Andrew Mertz, William Slough

Faculty Research and Creative Activity

Beautiful and expressive documents often require beautiful and expressive graphics. PGF and its front-end TikZ walk a fine line between power, portability and usability, giving a TEX-like approach to graphics. While PGF and TikZ are extensively documented, first-time users may prefer learning about these packages using a collection of graduated examples. The examples presented here cover a wide spectrum of use and provide a starting point for exploration.

Beautiful and expressive documents often require beautiful and expressive graphics. PGF and its front-end TikZ walk a thin line between power, portability and usability, giving a TEX-like approach to graphics. While PGF and TikZ are extensively documented, first-time users may prefer learning about these packages using a collection of graduated examples. The examples presented here cover a wide spectrum of use and provide a starting point for exploration.


Programming With Perltex, Andrew Mertz, William Slough Jan 2007

Programming With Perltex, Andrew Mertz, William Slough

Andrew Mertz

PerlTEX couples two well-known worlds—the Perl programming language and the LATEX typesetting system. The resulting system provides users with a way to augment LATEX macros with Perl code, thereby adding programming capabilities to LATEX that would otherwise be difficult to express. In this paper, we illus- trate the use of PerlTEX with a variety of examples and explain the associated Perl code. Although Perl may perhaps be best known for its string manipula- tion capabilities, we demonstrate how PerlTEX indirectly provides support for “programming” graphics through the use of additional packages such as TikZ.


Performance Analysis Of Security Aspects In Uml Models, Dorin Bogdan Petriu, Dorina C. Petriu, C Murray Woodside, Jing Xiu, Toqeer A. Israr, Geri Georg, Robert B. France, James M. Bieman, Siv Holde Houmb, Jan Jurjens Jan 2007

Performance Analysis Of Security Aspects In Uml Models, Dorin Bogdan Petriu, Dorina C. Petriu, C Murray Woodside, Jing Xiu, Toqeer A. Israr, Geri Georg, Robert B. France, James M. Bieman, Siv Holde Houmb, Jan Jurjens

Faculty Research & Creative Activity

The focus of the paper is on the analysis of performance effects of different security solutions modeled as aspects in UML. Aspect oriented modeling (AOM) allows software designers to isolate and separately address solutions for crosscutting concerns, which are defined as distinct UML aspect models, then are composed with the primary UML model of the system under development. For performance analysis we use techniques developed previously in the PUMA project, which take as input UML models annotated with the standard UML Profile for Schedulability, Performance and Time (SPT), and transform them first into Core Scenario Model (CSM) and then into …

2-Aminopyrimidine-3,3,3-Triphenyl- Propanoic Acid (1/1), Mateusz F. Serafin, Kraig A. Wheeler

Faculty Research and Creative Activity

The title bimolecular compound, C4H5N3·C21H18O2, constructed from 2-aminopyrimidine and 3,3,3-triphenylpropanoic acid, forms a tetramolecular hydrogen-bonded motif via O—H...N, N—H...O and N—H...N contacts. This aggregate organizes to give crystal-packing motifs with hydrophilic and hydrophobic regions.
