An On-Chip Pvt Resilient Short Time Measurement Technique, Esrafil Jedari Sefidgari

Electronic Theses and Dissertations

As the CMOS technology nodes continue to shrink, the challenges of developing manufacturing tests for integrated circuits become more difficult to address. To detect parametric faults of new generation of integrated circuits such as 3D ICs, on-chip short-time intervals have to be accurately measured. The accuracy of an on-chip time measurement module is heavily affected by Process, supply Voltage, and Temperature (PVT) variations. This work presents a new on-chip time measurement scheme where the undesired effects of PVT variations are attenuated significantly. To overcome the effects of PVT variations on short-time measurement, phase locking methodology is utilized to implement a …

How Is Shame Resolved? An Experimental Study On The Roles Of Anger And Sadness, Tsubasa Sawashima

Electronic Theses and Dissertations

Introduction: The aim of the current study was to explore emotional sequences involved in resolving shame, with a primary focus on comparing the effects of facilitating anger vs. facilitating sadness in the context of shame activation. The main hypothesis posited that facilitating anger, as opposed to sadness, would better promote emotional recovery from shame. This was inspired by an emerging line of research suggesting that facilitating an emotion that is incongruent (e.g., anger), as opposed to congruent (e.g., sadness), in its action tendency with the emotional distress presenting (e.g., shame) might better promote emotional outcome. Method: A randomized experimental design …

Leveraging Relocations In Elf-Binaries For Linux Kernel Version Identification, Manish Bhatt

University of New Orleans Theses and Dissertations

In this paper, we present a working research prototype codeid-elf for ELF binaries based on its Windows counterpart codeid, which can identify kernels through relocation entries extracted from the binaries. We show that relocation-based signatures are unique and distinct and thus, can be used to accurately determine Linux kernel versions and derandomize the base address of the kernel in memory (when kernel Address Space Layout Randomization is enabled). We evaluate the effectiveness of codeid-elf on a subset of Linux kernels and find that the relocations in kernel code have nearly 100\% code coverage and low similarity (uniqueness) across various kernels. …

Subculture And Queer Subjectivity, Natalie Woodlock

University of New Orleans Theses and Dissertations

My work explores subculture as a form of cultural resistance to the dominant ideology. I'm concerned with the ambiguous relationship we occupy as subjects to the material produced by popular culture, and how this is digested and understood by female viewers and cultural outsiders. The specific temporality of the queer subject is a key theme in my work.

Understanding The Impacts Of Current And Future Environmental Variation On Central African Amphibian Biodiversity, Courtney A. Miller

University of New Orleans Theses and Dissertations

Global climate change is projected to impact multiple levels of biodiversity by imposing strong selection pressures on existing populations, triggering shifts in species distributions, and reorganizing entire communities. The Lower Guineo-Congolian region in central Africa, a reservoir for amphibian diversity, is predicted to be severely affected by future climate change through rising temperatures and greater variability in rainfall. Geospatial modelling can be used to assess how environmental variation shapes patterns of biological variation – from the genomic to the community level – and use these associations to predict patterns of biological change across space and time. The overall goal of …

A Change In Grain? Diet Induced Plasticity In The Generalist Grasshopper Melanoplus Differentialis, Austin M. Culotta

University of New Orleans Theses and Dissertations

Phenotypic plasticity is favored in heterogeneous environments in which alternative phenotypes can exploit alternative resources. However, it’s not clear whether phenotypic plasticity is useful in environments that become more homogenous over an organism’s life cycle. I studied a population of grasshopper Melanoplus differentialis that experiences high resource diversity as nymphs but low resource diversity as adults to determine if individuals can undergo diet-induced morphological plasticity in head shape to increase biting ability and ingestion of hard diets. Insects on a soft diet were larger and had greater bite force than those on a hard diet. Head structures related to chewing …

The Desire To Escape And The Inability To Follow Through In James Joyce’S Dubliners, Alyssa M. Wheatley

In my research, I will examine James Joyce’s Dubliners as a collection of stories that is unified by an ongoing theme; escape or the desire to escape. In the collection, the want or need to escape serves a major purpose throughout the characters and their lives. This thesis explores five stories that share this theme in particular: “The Sisters,” “Eveline,” “Araby,” “An Encounter,” and “The Dead.” Each story will be discussed in the context of how each story progresses from a want to an actual escape. In addition, the thesis also considers how these stories exhibit a progression towards isolation …

Shaking The Frame: Graduates' Perceptions Of A School Leadership Program With A Social Justice Focus, Cherie H. Goins

University of New Orleans Theses and Dissertations

Abstract

Educational leaders who have an awareness of social justice are those who advocate for and achieve more equitable schools. School leader preparation programs that focus on social justice may help to improve schools, systems, and society (Dentith & Peterlin, 2011; Boske, 2012; Marshall and Oliva, 2006; Shields, 2004, 2010, 2012). For the purpose of this study, social justice is defined as fairness in terms of distribution of wealth, social privileges and opportunities within society. Some school leaders experience transformative processes which increase their critical awareness or consciousness during their formal preparation.

Legacy Habitat Suitability Of Eastern Oysters (Crassostrea Virginica) In Louisiana: A Prelude To Mississippi River Delta Freshwater Diversions, Tasia Mv Denapolis

University of New Orleans Theses and Dissertations

The Louisiana oyster industry is greatly impacted by freshwater and sediment diversions that are part of the effort to restore the state’s coastline. A habitat suitability index (HSI) proposes species-habitat relationships that can be instrumental in creating impact assessments and suitability predictions for management as new diversions are implemented. An oyster (Crassostrea virginica) HSI was developed using three variables crucial to oyster sustainability: average annual salinity, minimum monthly salinity, and average salinity during the spawning season. These Legacy HSI visualizations show annual fluctuations in the distribution of zones suitable for oyster cultivation prior to proposed diversions in Pontchartrain …

Automating The Detection Of Precipitation And Wind Characteristics In Navy Ocean Acoustic Data, Joseph T. Kuhner

University of New Orleans Theses and Dissertations

A challenge in Underwater Acoustics is identifying the independent variables associated with an environment’s ambient noise. A strict definition of ambient noise would focus on non-transient signatures and exclude transient impacts from marine mammals, pelagic fish species, man-made sources, or weather events such as precipitation or wind speeds. Recognizing transient signatures in acoustic spectra is an essential element for providing environmental intelligence to the U.S. Navy, specifically the acoustic signatures from meteorological events. While weather event detection in acoustic spectra has been shown in previous studies, leveraging these concepts via U.S. Navy assets is largely an unknown. Environmental intelligence collection …

The Effects Of Sediment Properties On Barrier Island Morphology And Processes: A Numerical Modeling Experiment, Brittany Kime

University of New Orleans Theses and Dissertations

Barrier island restoration and nourishment is necessary for sustaining coastal systems worldwide. In the Mississippi River Delta Plain, the lack of sediment supply, relative sea level rise, and reworking of abandoned delta lobes promote rapid disintegration of barriers, which can contribute to mainland storm impacts. Barrier island restorations that utilize higher quality sediments (Outer Continental Shelf- OCS) are expected to exhibit higher resiliency, withstanding coastal erosion, event-induced erosion, and ongoing transgression when compared to barriers nourished using lower quality nearshore (NS) sands. Additionally, use of OCS sediments increases sediment supply by adding material to the system supporting increased barrier longevity …

Predicting Software Fault Proneness Using Machine Learning, Sanjay Ghanathey

Electronic Thesis and Dissertation Repository

Context: Continuous Integration (CI) is a DevOps technique which is widely used in practice. Studies show that its adoption rates will increase even further. At the same time, it is argued that maintaining product quality requires extensive and time consuming, testing and code reviews. In this context, if not done properly, shorter sprint cycles and agile practices entail higher risk for the quality of the product. It has been reported in literature [68], that lack of proper test strategies, poor test quality and team dependencies are some of the major challenges encountered in continuous integration and deployment.

Romance, Politics And Minor Art: A Nomadology Of Inamoramento De Orlando And Star Wars, Andrea Privitera

Electronic Thesis and Dissertation Repository

While existing theories of romance (in particular, those formulated by Northrop Frye and Fredric Jameson) accurately characterize this literary mode as a highly politicized example of art, this thesis contends that the political nature of romance is broader and more complex than discussed so far. In order to offer a new and comprehensive political theory of romance, this work proposes a comparison between two historically and culturally diverse examples of romance, that is Matteo Maria Boiardo’s chivalric poem Inamoramento de Orlando and George Lucas’ space opera film Star Wars. By reading Boiardo and Lucas’ texts via Gilles Deleuze and …

A Simulated Learning Experience In Advanced Care Planning Conversations, Brandy Ellis

Doctor of Nursing Practice (DNP) Translational and Clinical Research Projects

Background: The CDC (2012) reports that 1/3 of Americans have no advance care planning (ACP), which is essential for maintaining autonomy when people are no longer able to communicate wishes directly. IOM (2014) reports that providers have limited training in communication techniques and low confidence in holding advanced care planning conversations. Nursing simulation is an effective method of teaching clinical skills in a safe environment. The development of a high fidelity (HF) standardized patient simulation, using the Jeffries Simulation Framework, combined with evidence-based practice classroom curriculum, may increase knowledge and confidence in holding ACP conversations for nurse practitioner students.

An Application Of Deep-Learning To Understand Human Perception Of Art, Sanjana Kapisthalam

Theses

Eye movement patterns are known to differ when looking at stimuli given a different task, but less is known about how these patterns change as a function of expertise. When a particular visual pattern is viewed, a particular sequence of eye movements are executed and this sequence is defined as scanpath. In this work we made an attempt to answer the question, “Do art novices and experts look at paintings differently?” If they do, we should be able to discriminate between the two groups using machine learning applied to their scanpaths. This can be done using algorithms for Multi-Fixation Pattern …
