Influence Maximization On Families Of Graphs, Andrei Mouravski Jan 2011

Influence Maximization On Families Of Graphs, Andrei Mouravski

Theses

We examine computing the maximum expected influence on paths and trees using the independent cascade model. We designed a polynomial time method for determining the expected influence from any initial state on the independent cascade model on acyclic influence graphs in O(|V(G)|² · max {|V(G)|,|V(E)|}) time. We designed a polynomial time program that would computes the maximum expected influence and optimal initially selected nodes on arbitrary paths in O(|V(T)|⁶/[epsilon]) on approximating the maximum expected influence on arbitrary trees with absolute error of at most ([epsilon] · 2|V(T)|).

Mitigating The Risk Of Social Engineering Attacks, Matthew Spinapolice Jan 2011

Mitigating The Risk Of Social Engineering Attacks, Matthew Spinapolice

Theses

The topic of social engineering is only covered briefly in today's system administration and security coursework. This lack of coverage leaves many Administrators ill-equipped to administer the users of a computer network. In addition to their technical training, administrators need to comprehend the potential severity and likelihood of social engineering attacks. Teaching administrators only to minimize the risk of hacking attempts or computer virus infections does not fully equip them with the knowledge needed to defend their networks. To ensure the safety of their network from social engineering attacks, administrators need to be able to answer three primary questions: * …

Markov Chain Monte Carlo On The Gpu, Michael Dumont Jan 2011

Markov Chain Monte Carlo On The Gpu, Michael Dumont

Theses

Markov chains are a useful tool in statistics that allow us to sample and model a large population of individuals. We can extend this idea to the challenge of sampling solutions to problems. Using Markov chain Monte Carlo (MCMC) techniques we can also attempt to approximate the number of solutions with a certain confidence based on the number of samples we use to compute our estimate. Even though this approximation works very well for getting accurate results for very large problems, it is still computationally intensive. Many of the current algorithms use parallel implementations to improve their performance. Modern day …

Layout-Based Substitution Tree Indexing And Retrieval For Mathematical Expressions, Matthew Schellenberg Jan 2011

Layout-Based Substitution Tree Indexing And Retrieval For Mathematical Expressions, Matthew Schellenberg

Theses

We introduce a new system for layout-based indexing and retrieval of mathematical expressions using substitution trees. Substitution trees can efficiently store and find hierarchically-structured data based on similarity. Previously Kolhase and Sucan applied substitution trees to indexing mathematical expressions in operator tree representation (Content MathML) and query-by-expression retrieval. In this investigation, we use substitution trees to index mathematical expressions in symbol layout tree representation (LaTeX) to group expressions based on the similarity of their symbols, symbol layout, sub-expressions and size. We describe our novel substitution tree indexing and retrieval algorithms and our many significant contributions to the behavior of these …

Evanescent Wave Assist Features For Optical Projection Lithography, Neal Lafferty Jan 2011

Evanescent Wave Assist Features For Optical Projection Lithography, Neal Lafferty

Theses

Evanescent Wave Assist Features (EWAFs) are features that are sensitive to near-field radiation that modify diffracted order intensities from photomask patterns. In implementations studied in this thesis, the EWAFs increase a transmitting feature's image contrast and Normalized Image Log Slope (NILS). In this way, the EWAFs are a way to improve image fidelity for high-resolution features. The assist features consist of local, buried grooves located around transmitting mask regions. These grooves reside in otherwise unused areas, since they are located under or on top of opaque mask absorber regions. In these "buried" locations, they are not optically visible to the …
