Explaining The Performance Of Bidirectional Dijkstra And A* On Road Networks, Sneha Sawlani Jan 2017

Explaining The Performance Of Bidirectional Dijkstra And A* On Road Networks, Sneha Sawlani

Electronic Theses and Dissertations

The heuristic search community traditionally uses A* as the baseline algorithm for their research methods. Research papers in the road networks community, however, often build upon Dijkstra's algorithm and use Bidirectional Dijkstra's algorithm as their baseline. This thesis investigates the performance of A* and Bidirectional Dijkstra in road networks to see how they compare and to see if there is a principled explanation for the different approaches. Our analysis reveals why Bidirectional Dijkstra can perform well in this domain, but also shows a simple mistake that can be made when building test problems that hurts the performance of A*.

The Ethics Of Representation: Muslim Women Reenacting And Resisting Whiteness, Haneen Al Ghabra Jan 2017

The Ethics Of Representation: Muslim Women Reenacting And Resisting Whiteness, Haneen Al Ghabra

Electronic Theses and Dissertations

This study examines Muslim women's performances and embodiment of White femininity. It addresses invisibility/visibility and problematic rhetorical constructs for re-securing and replicating White femininity, which in turn reasserts White masculinity as the dominant ideological structure in service of Whiteness. To be exact, the aim is to specifically focus on how Whiteness travels globally through Muslim bodies and subjects who speak the language of the imperialist and not the vernacular. This language of the imperialist is also the language of heteronormativity, class, and educational privilege. These intersections are not stand-alone categories but instead seep into one another in the service of …

Moral Psychology And Political Campaigns, Joel Andrew Hanel Jan 2017

Moral Psychology And Political Campaigns, Joel Andrew Hanel

Electronic Theses and Dissertations

Theories of moral psychology suggest that American partisans rely on different moral domains to inform their political decision making (Haidt 2012; Lakoff 1996). This project addresses the use of moral framing, language, and traits in American political campaigns. It first examines the language of campaigns to ascertain if Democratic and Republican candidates use moral language in line with moral theories and then attempts to understand if using this language can affect the public in a meaningful way. Overall, the research suggests that campaigns frequently use moral language, though it does not strictly conform to the predictions of existing moral theory …

Compact Objects In Relativistic Theories Of Gravity, Hector Okada Da Silva Jan 2017

Compact Objects In Relativistic Theories Of Gravity, Hector Okada Da Silva

Electronic Theses and Dissertations

In this dissertation we discuss several aspects of compact objects, i.e. neutron stars and black holes, in relativistic theories of gravity. We start by studying the role of nuclear physics (encoded in the so-called equation of state) in determining the properties of neutron stars in general relativity. We show that low-mass neutron stars are potentially useful astrophysical laboratories that can be used to constrain the properties of the equation of state. More specifically, we show that various bulk properties of these objects, such as their quadrupole moment and tidal deformability, are tightly correlated. Next, we develop a formalism that aims …

Noise Thinks The Anthropocene: An Experiment In Noise Poetics, Aaron Zwintscher Jan 2017

Noise Thinks The Anthropocene: An Experiment In Noise Poetics, Aaron Zwintscher

Electronic Theses and Dissertations

This dissertation is a textual experiment in noise poetics. It is an experiment in that it results from indeterminate means, alternative grammar, and experimental thinking. The outcome was not predetermined. Noise poetics is the use of noise to explain, elucidate, and evoke (akin to other poetic forms) within the textual milieu in a manner that seeks to be less determinate and more improvisational than conventional writing. This text argues that noise poetics is a necessary form for addressing political inequality, coexistence with the (nonhuman) other, the ecological crisis, and sustainability because it approaches these issues as system of interconnected fragments …
