Analysis Of Supercomputers And Development Of A Novel Network, Reid Powell

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

As supercomputers have reached nearly 300,000 cores with 2 petaflops in Linpack performance in June 2010, energy consumption and temperature control are posing a developmental bottleneck. We retrospectively and comparatively examine all of the available data contained in the Green500 list that launched in November 2007, and the Top500 list, and propose a novel representation and analysis of the data, highlighting major evolutionary trends.With these new insights, we introduce a new technique for generating more efficient networks by systematically interlacing bypass rings to torus networks (iBT networks). The resulting network can improve the original torus network by reducing the network …

Shear-Induced Platelet Sensitization And The Development Of An Activation Model, Jawaad Sheriff

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Increased shear stresses are a hallmark of flow conditions in blood recirculating devices, and patients implanted with such devices require lifelong anticoagulation to counteract the high risk of thromboembolism. Despite this limitation, manufacturers only test for hemolysis in order to optimize device design. This is primarily due to the paucity of data regarding platelet damage, a major precursor of thromboembolism. Several studies have shown that platelets exposed to constant shear stress for a specified duration become activated. However, post high-shear stress activation behavior of platelets, which is critical to understanding increased thrombotic risk associated with blood recirculating devices, is poorly …

Reading Into Race: Unsettled Reading And The Performance Of"Race", Julie Burton Swift

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Reading, race, and the primary productive link between the two--performativity--are the subject of this dissertation. By reading the formative discourse of phrenology and Ethnology, as well as nineteenth-century textbooks which teach reading, I suggest a context in which reading operates as an expressive framework for the problematics of race. In considering selected works of Edgar Allan Poe, Frederick Douglass, Harriet Jacobs, and Herman Melville, I examine the uses to which reading is put, not only to elaborate, but to perform race. By looking at unsettled reading--breakdowns of reading, failures to read, readings that prove unaccountable to the text--I emphasize the …

Classification Problems For Mdps And Optimal Customer Admission To M/M/K/N Queues, Fenghsu Yang

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

My dissertation addresses the unichain classification problem for any finite Markov decision process (MDP) with a recurrent or stopping state and the optimal admission problem for an M/M/k/N controlled queue with holding costs. In the first chapter, we study the unichain classification problem for MDPs. The unichain classification problem is to detect whether an MDP with finite states and actions is unichain or not. This problem has been proven to be NP-hard. We study this problem while an MDP contains a state which is either recurrent under all deterministic policies or absorbing under some action. We introduce the definitions of …

Design And Optimization On Mobile Data Gathering In Wireless Sensor Networks, Miao Zhao

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Wireless sensor networks (WSNs) have emerged as a new information-gathering paradigm for taking spatial and temporal measurements of a given set of real-word parameters. In these applications, sensors monitor the environment and route their sensing data back to a static data sink. As the routing task depends purely on sensors themselves, the sensors near the sink need to relay much more packets than the sensors far away from the sink. As the result, it would incur substantial and non-uniform energy consumption among sensors. Therefore, how to efficiently aggregate the information from scattered sensors, generally referred to as data gathering, is …

The Specific Interactions Between Dendritic Cells And Porphyromonas Gingivalis, Amir Emanuel Zeituni

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The broad objective of this dissertation is to elucidate the specific interactions between Porphyromonas gingivalis (P. gingivalis) and dendritic cells (DCs). P. gingivalis is a black pigmented, anaerobic, Gram-negative bacterium that is associated with most cases of chronic periodontitis. P. gingivalis expresses a myriad of virulence factors, most notably, fimbrial adhesins that enable it to bind to and invade host epithelial cells, endothelial cells, macrophages and DCs. While much is known about the 41 kDa major fimbria adhesins of P. gingivalis, the minor fimbriae have received little attention. The results presented here suggest that the minor fimbriae may serve as …

Targeting And Roles Of Complexins In Zebrafish Ribbon-Containing Neurons, George Zanazzi

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The primary receptor cells of the visual, auditory, vestibular and lateral line systems encode a broad range of sensory information by modulating the tonic release of the neurotransmitter glutamate in response to graded changes in membrane potential. The output synapses of these neurons are marked by structures called synaptic ribbons, which tether a pool of releasable synaptic vesicles at the active zone. Despite the importance of the ribbon in synaptic transmission, the molecular mechanisms that govern the assembly and function of the exocytotic machinery in these terminals are poorly understood. We have identified a subfamily of SNARE complex regulators, composed …

Multi-Threshold Cmos Circuit Design Methodology From 2d To 3d, Ross Josiah Thian

Graduate Theses and Dissertations

A new and exciting approach in digital IC design in order to accommodate the Moore's law is 3D chip stacking. Chip stacking offers more transistors per chip, reduced wire lengths, and increased memory access bandwidths. This thesis demonstrates that traditional 2D design flow can be adapted for 3D chip stacking. 3D chip stacking has a serious drawback: heat generation. Die-on-die architecture reduces exposed surface area for heat dissipation. In order to reduce heat generation, a low power technique named Multi-Threshold CMOS (MTCMOS) was incorporated in this work. MTCMOS required designing a power management unit (to control when and which gates …

Memory For Emotionally Provocative Words In Alexithymia: A Role For Stimulus Relevance, Mitchell Meltzer, Kristy A. Nielson

Psychology Faculty Research and Publications

Alexithymia is associated with emotion processing deficits, particularly for negative emotional information. However, also common are a high prevalence of somatic symptoms and the perception of somatic sensations as distressing. Although little research has yet been conducted on memory in alexithymia, we hypothesized a paradoxical effect of alexithymia on memory. Specifically, recall of negative emotional words was expected to be reduced in alexithymia, while memory for illness words was expected to be enhanced in alexithymia.

Eighty-five high or low alexithymia participants viewed and rated arousing illness-related ("pain"), emotionally positive ("thrill"), negative ("hatred"), and neutral words ("horse"). Recall was assessed 45 …

Ftp-Like Streams For The 9p File Protocol, John Floren

Theses

The Plan 9 operating system from Bell Labs has broken a great deal of new ground in the realm of operating systems, providing a lightweight, network-centric OS with private namespaces and other important concepts. In Plan 9, all file operations, whether local or over the network, take place through the 9P file protocol. Although 9P is both simple and powerful, developments in computer and network hardware have over time outstripped the performance of 9P. Today, file operations, especially copying files over a network, are much slower with 9P than with protocols such as HTTP or FTP. 9P operates in terms …

Our Country Right Or Wrong: A Pragmatic Response To Anti-Democratic Cultural Nationalism In China, Sor-Hoon Tan

Research Collection School of Social Sciences

Since Deng Xiaoping came into power, China has been described as pragmatic in its approach to politics and development, and in the nineties there has been a revival of interest in Chinese cultural tradition. What is the relation between these two phenomena? Do they coexist, separately in mutual indifference, or in tension? Has there been constructive engagement, or at the very least does the potential for such engagement exist? More specifically, what roles, if any, do they play in China's quest for democracy? Does Dewey's pragmatism have any relevance to China in the twenty-first century? The issue of cultural tradition …

Operation Opera: An Ambiguous Success, Joshua Kirschenbaum

Journal of Strategic Security

To assess the efficacy of Israel's strike on Osirak, one must determine Israel's strategic objectives and their material effects on Iraqi capabilities. The capacity of the facilities to produce fissionable material without detection remains in dispute. So, too, does the timeline—and therefore the imminence—of Iraqi acquisition of a nuclear option. The political cost-benefit equation in this case requires a fair dose of subjective judgment. How much did the Israelis delay the program? How much did Iraqi motivation increase post facto? Is military counter-proliferation a viable strategy? Was the potential Iraqi bomb worth risking a bold, unprovoked attack that inevitably drew …

Devolving Jihadism, Aaron Rosler

Journal of Strategic Security

The danger and effectiveness of religiously motivated terrorist organizations is undeniable. However, a different type of threat is on the rise on the global playing field as a result of the ongoing operations against these organizations. "Devolved" jihadism, Islamist terrorism conducted by native, amateur, untrained and unfunded individuals, or small ad hoc groups, has recently garnered headlines and the attention of terrorists and counterterrorists alike. These devolved jihadist operations are planned and carried out by native members of a country's populace, radicalized in their home country, resulting in the interchangeable monikers of "homegrown" or "grassroots" jihadism.

Tidal Current Energy Resource Assessment In Ireland: Current Status And Future Update, Fergal O'Rourke, Fergal Boyle, Anthony Reynolds

Articles

Interest in renewable energy in Ireland has increased continually over the past decade. This interest is due primarily to security of supply issues and the effects of climate change. Ireland imports over 90% of its primary energy consumption, mostly in the form of fossil fuels. The exploitation of Ireland’s vast indigenous renewable energy resources is required in order to reduce this over dependence on fossil fuel imports to meet energy demand. Various targets have been set by the Irish government to incorporate renewable energy technologies into Ireland’s energy market. As a result of these targets, the development in wind energy …

Recasting Genre In Tennessee Williams's Apprentice Plays, Christina Ilona Hunter

Dissertations

This dissertation investigates Tennessee Williams’s earliest full-length plays, also known as the apprentice plays—Candles to the Sun, Fugitive Kind, Not About Nightingales, Spring Storm, and Stairs to the Roof—by comparing, contrasting and contextualizing them in relation to Daniel Chandler’s generic criteria of drama; namely, narrative, characterization, setting, topics, iconography, and staging techniques. The present study also draws upon an extensive body of scholarship pertaining to genre theory, Williams’s cultural contemporaries, and the historical and psychological backdrop of Depression-era America. In these early plays, Williams diverged sharply from the dramatic generic conventions of his day, manipulating them in new …
