Data Routing In Multicore Processors Using Dimension Increment Method, Arpita H. Kadakia

UNLV Theses, Dissertations, Professional Papers, and Capstones

A Deadlock-free routing algorithm can be generated for arbitrary interconnection network using the concept of virtual channels but the virtual channels will lead to more complex algorithms and more demands of NOC resource.

In this thesis, we study a Torus topology for NOC application, design its structure and propose a routing algorithm exploiting the characteristics of NOC. We have chosen a typical 16 (4 by 4) routers Torus and propose the corresponding route algorithm. In our algorithm, all the channels are assigned 4 different dimensions (n0,n1,n2 & n3). By following the dimension increment method, we break the dependent route circles, …

The Interaction Of Rock And Water During Shock Decompression: A Hybrid Model For Fluidized Ejecta Formation, Audrey Hughes Rager

UNLV Theses, Dissertations, Professional Papers, and Capstones

Crater and ejecta morphology provide insight into the composition and structure of the target material. Martian rampart craters, with their unusual single-layered (SLE), double-layered (DLE), and multi-layered ejecta (MLE), are the subject of particular interest among planetary geologists because these morphologies are thought to result from the presence of water in the target. Also of interest are radial lines extending from the crater rim to the distal rampart of DLE craters. Exactly how these layered ejecta morphologies and radial lines form is not known, but they are generally thought to result from interaction of the ejecta with the atmosphere, subsurface …

Detention Basins For Phosphorus And Sediment Control In Clark County, Nevada, Amina Rashid Lodhi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Nonpoint source urban stormwater runoff degrades aquatic ecosystems, and causes flooding. To mitigate its effects on natural and human environments best management practices (BMPs) became popular strategies to protect the integrity of water quality. Similarly, to mitigate the effects of stormwater quantity, detention basins (DBs) were put into place as flood control structures. Water quality control remains an unexplored and important aspect of DB utility, particularly, in arid regions. Since DBs are depressions in the earth and retain water over the course of several hours to days after a rain event, they can potentially act as BMPs. A key pollutant …

Production, Purification And Crystallization Of Membrane Integrated Multimeric Bax, Adelbert Mark Villoso

UNLV Theses, Dissertations, Professional Papers, and Capstones

Apoptosis, or programmed cell death, is a vital process intimately involved in the embryonic development and homeostatic maintenance of all multicellular organisms. The committing step to apoptosis is regulated by a key protein, Bax, and its ability to integrate and form a pore structure at the outer mitochondrial membrane.

Unfortunately, the molecular details of apoptosis remain largely unclear due to the lack of structural data of integral membrane (IM) Bax. Experimental limitations of membrane protein production have slowed the pursuit of an IM-Bax structure simply because standard protocols for producing recombinant IM-Bax are inefficient in producing adequate quantities of IM-Bax …

History And Transnational Identities In Junot Díaz’S The Brief Wondrous Life Of Oscar Wao, Brian Joseph Flores

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of my thesis is to analyze Junot Díaz’s The Brief Wondrous Life of Oscar Wao and evaluate the role literature plays within the larger context of the relationship among the different countries and cultures in the Western Hemisphere, as well as the place historical events play within this understanding. In Díaz’s novel, there is an understanding of the presence of multiple cultural identities. This awareness of multiple cultural identities leads to the difficulty the characters encounter when trying understanding themselves as individuals. On a much larger scale, the characters also try to understand their cultural, social, and historical …

Dynamic Distributed Programming And Applications To Swap Edge Problem, Feven Z. Andemeskel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Link failure is a common reason for disruption in communication networks. If communication between processes of a weighted distributed network is maintained by a spanning tree T, and if one edge e of T fails, communication can be restored by finding a new spanning tree, T’. If the network is 2-edge connected, T’ can always be constructed by replacing e by a single edge, e’, of the network. We refer to e’ as a swap edge of e.

The best swap edge problem is to find the best choice of e’, that is, that e which causes the new spanning …

Building Dupont: Capitalism, Manufactures, And Place In Early America, 1800-1820, Christopher Manning

UNLV Theses, Dissertations, Professional Papers, and Capstones

Though there is a rich literature dealing with the DuPont Company, the historiography remains dedicated to studies of the family’s life, corporate methods, working-class culture, and technological know-how. Rarely do studies engage the company’s wider economic position or regional influence in early America. This study analyzes the way early American culture guided and influenced DuPont’s growth and success. It also examines the company’s efforts to promote manufactures, create markets, and shape its surrounding landscape. As in other parts of the world, the development of industrial capitalism, and the wider acceptance of domestic manufacturers and large-scale industry in the United States …

Carbon Isotopic Fractionation Across A Late Cambrian Carbonate Platform: A Regional Response To The Spice Event As Recorded In The Great Basin, Jonathan Lloyd Baker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Geochemical models have suggested that the late Cambrian was characterized by a greenhouse climate with high pCO2. Furthermore, stableisotope analyses within the Great Basin have documented a large carbonate isotope (δ13Ccarb) excursion, known as the Steptoean Positive Carbon Isotope Excursion (SPICE). This event has been documented globally, and is interpreted as having resulted from enhanced organic carbon burial. Unless the size of carbon reservoirs in the Cambrian ocean was significantly different from those of the Cenozoic, this forcing should have resulted in a comparable carbon-isotope excursion in organic matter (δ13Corg). It is also predicted that increased organic carbon burial would …

Self-Stabilizing Leader Election In Dynamic Networks, Hema Piniganti

UNLV Theses, Dissertations, Professional Papers, and Capstones

The leader election problem is one of the fundamental problems in distributed computing. It has applications in almost every domain. In dynamic networks, topology is expected to change frequently. An algorithm A is self-stabilizing if, starting from a completely arbitrary configuration, the network will eventually reach a legitimate configuration.

Note that any self-stabilizing algorithm for the leader election problem is also an algorithm for the dynamic leader election problem, since when the topology of the network changes, we can consider that the algorithm is starting over again from an arbitrary state. There are a number of such algorithms in the …

Development Of Novel Biomarkers In Cancer: Detection Of Circulating Mir-141 As A Potential Prognostic Marker For Prostate Cancer, Jason Cadaoas Gonzales

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prostate cancer (CAP) is the most common epithelial malignancy and the second leading cause of cancer deaths in American men. The identification of predictive and prognostic biomarkers in CAP patients is critical for improving clinical outcomes. Although the measurement of prostate-specific antigen (PSA) and radiographic studies are clinically approved to predict response to therapy, these tests can oftentimes prove to be inadequate in certain patients. Thus, it is important to discover new biomarkers to improve chances of survivability. We and others have shown that longitudinal measurements of circulating tumor cells (CTC) and lactate dehydrogenase (LDH) may aid in predicting response …

The Crooked Median, Monica Zarazua

UNLV Theses, Dissertations, Professional Papers, and Capstones

Words search. There are specific points designated by written language, where one might stand for just a little while until the satisfaction of a pattern is revealed. In this collection of stories, one of the forces that serves as a catalyst for this search is the outside gaze. The gaze exerts itself onto characters. The characters may or may not be conscious of it, may or may not welcome it, but they must grapple with it. The gaze projects its needs and desires onto the characters. It seeks to control them, and it desires to be viewed with admiration, lowered …

Age And Petrogenesis Of The Roaring Mountain Rhyolites, Yellowstone Volcanic Field, Wyoming, Kathleen Marie Wooton

UNLV Theses, Dissertations, Professional Papers, and Capstones

Extracaldera rhyolites in the Norris-Mammoth Corridor of the Yellowstone Volcanic Field (YVF) appear to be unrelated to intracaldera volcanism, resulting instead from a new crustal magma source derived from northeastward propagation of the Yellowstone “melting anomaly.” The youngest extracaldera rhyolite unit, the Roaring Mountain Member (RM), is chemically distinct from the previous extracaldera lavas, reverting to more primitive compositions.

This study suggests that the majority of the RM rhyolites erupted from the same large-scale silicic magma system. Based on geochemistry and 40Ar/39Ar geochronology, the Crystal Spring mingled rhyolite and Obsidian Cliff rhyolite erupted concurrently at 59.1 ± 2.0 ka. The …

Self-Stabilizing Group Membership Protocol, Mahesh Subedi

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this thesis, we consider the problem of partitioning a network into groups of bounded diameter.

Given a network of processes X and a constant D, the group partition problem is the problem of finding a D-partition of X, that is, a partition of X into disjoint connected subgraphs, which we call groups, each of diameter no greater than D. The minimal group partition problem is to find a D-partition {G1, ... Gm} of X such that no two groups can be combined; that is, for any Gi and Gj, where i ≠ j, either Gi U Gj is disconnected …
