Holocene Glacial Activity In Barilari Bay, West Antarctic Peninsula, Tracked By Magnetic Mineral Assemblages: Linking Ice, Ocean, And Atmosphere, Brendan Reilly, Carl Natter, Stefanie A. Brachfeld

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

We investigate the origin and fate of lithogenic sediments using magnetic mineral assemblages in Barilari Bay, west Antarctic Peninsula (AP) from sediment cores recovered during the Larsen Ice Shelf System, Antarctica (LARISSA) NBP10-01 cruise. To quantify and reconstruct Holocene changes in covarying magnetic mineral assemblages, we adopt an unsupervised mathematical unmixing strategy and apply it to measurements of magnetic susceptibility as a function of increasing temperature. Comparisons of the unmixed end-members with magnetic observations of northwestern AP bedrock and the spatial distribution of magnetic mineral assemblages within the fjord, allow us to identify source regions, including signatures for ‘‘inner bay,’’ …

The proposed models aim to improve the utilization of the demand side energy through load management programs including peak shaving, load shifting, and valley lling. First, a model is proposed to nd the optimal capacity of the battery energy storage system (BESS) to …

Towards Computational Human Behavior Modeling For Just-In-Time Adaptive Interventions, Tylar Murray

USF Tampa Graduate Theses and Dissertations

The advent of powerful wearable devices and smartphones has enabled a new generation of “in-the-wild” user studies, adaptive behavioral intervention strategies, and context measurement. Though numerous proof-of-concept studies continue to push the limitations of what a behavioral scientist can do with these technologies, there remains a major methodological roadblock separating behavioral theory and application. Avatar-user interaction theory, for example, is not well defined in its formulation, and thus guidelines for intervention designers depend on heuristic methods and designer intuition. Computational modeling has been slow to move into behavioral science in general, but a growing population of behavioral scientists recognize this …

Hospitable Climates: Representations Of The West Indies In Eighteenth-Century British Literature, Marisa Carmen Iglesias

USF Tampa Graduate Theses and Dissertations

British expansion to the West Indies in the eighteenth-century resulted in vast economic growth for the British Empire and a rise in literature set in the region. Examining the literature allows for an in-depth exploration of how the Caribbean has become associated as a place of relaxation and escape though its early history of colonialism is fraught with violence. My study builds on the understanding of the Caribbean region in the eighteenth-century and utilizes hospitality theory to articulate the role that cultural exchange and physical setting play in the texts and in the formation of national identity, both in the …

A Review Of Evolution, Behavior, And Vision With An Experimental Evolution Study On Color Vision In Drosophila Melanogaster, Mellissa Ann Marcus

Theses

The first chapter of this thesis is to take a piece by piece look at the factors that contributed to the experimental evolution study that will be discussed in Chapter 2. Behavior, how that can affect experimental studies, and how biases can affect sensory systems and preference in subject species. Specifically visual sensory systems are described in detail, from the possible evolutionary histories, to major components that contribute to eye structure, form, and/or abilities. We discuss how to define color vision, and what are the prerequisites for color vision in species.

Chemical processes such as reactivity and the change of properties after exposure to external agents (e.g. durability) can also be explored. The results of my investigations can contribute to speeding up, …

A Framework For Studying Meshfree Geometry And A Method For Explicit Boundary Determination, Joseph Bradley Alford

USF Tampa Graduate Theses and Dissertations

Patient-specific biomechanical analysis is an important tool used to understand the complex processes that occur in the body due to physical stimulation. Patient-specific models are generated by processing medical images; once an object from the image is identified via segmentation, a point cloud representation of the object is extracted. Generating an analysis suitable representation from the point cloud has traditionally required generating a finite element mesh, which often requires a well defined surface to accomplish. Point clouds lack a well defined geometry, meaning that the surface definition is incomplete at best. Point clouds that have been generated from images have …

Hydrolytic And Nonhydrolytic Sol-Gel Zirconia-, Titania-, And Niobia-Based Capillary Microextraction Coatings For The Preconcentration And Hplc Analysis Of Catecholamine Neurotransmitters And Phosphorylated Peptides, Abdullah Awadh Alhendal

USF Tampa Graduate Theses and Dissertations

Sample preparation is the most error-prone step in chemical analysis. A great deal of efforts has been made to develop efficient techniques and protocols for sample preparation to accomplish important goals such as miniaturization and implementation of green analytical methodologies. Solid-phase microextraction (SPME) has successfully eliminated the use of hazardous organic solvents in extraction sampling, sample preparation, preconcentration and sample introduction to the analytical instrument in an effective manner. Ensuring thermal- and solvent-instability of traditional SPME extraction phases represented one of their main drawbacks. This was solved by the introduction of sol-gel SPME phases characterized by enhanced thermal-, solvent-, and …

Hygrothermal Risk Evaluation For The Retrofit Of A Typical Solid-Walled Dwelling, Benat Arregi, Joseph Little

SDAR* Journal of Sustainable Design & Applied Research

There is increasing evidence that current mainstream guidance for assessing moisture risk of insulation retrofits in Ireland and the UK is unsuitable for traditional solidwalled buildings. This guidance is still based on simplified hygrothermal risk assessment methods, despite the availability of more advanced numerical software for two decades and a relevant standard in place since 2007, EN 15026. Two-dimensional versions of these software applications can extend simulation beyond one-dimensional assemblies to more complex junctions. This exploratory study makes use of one of these advanced simulation tools, aided by physical measurement, to explore hygrothermal risks of solid wall retrofits at the …

Minimum Number Of Distinct Eigenvalues Of Graphs, Shahla Nasserasr

Mathematics Colloquium Series

For a simple graph G on n vertices, a real symmetric nxn matrix A is said to be compatible with G, if for different i and j, the (i; j) entry of A is nonzero whenever there is an edge between the vertices i and j, it is zero otherwise. The minimum number of distinct eigenvalues, when minimum is taken over all compatible matrices with G, is denoted by q(G). In this talk, a survey of some known and new results about q(G) is presented.

Germination And Growth Of Native And Invasive Plants On Soil Associated With Biological Control Of Tamarisk (Tamarix Spp.), Rebecca A. Sherry, Patrick B. Shafroth, Jayne Belnap, Steven Ostoja, Sasha C. Reed

United States Geological Survey: Staff Publications

Introductions of biocontrol beetles (tamarisk beetles) are causing dieback of exotic tamarisk in riparian zones across the western United States, yet factors that determine plant communities that follow tamarisk dieback are poorly understood. Tamarisk-dominated soils are generally higher in nutrients, organic matter, and salts than nearby soils, and these soil attributes might influence the trajectory of community change. To assess physical and chemical drivers of plant colonization after beetle-induced tamarisk dieback, we conducted separate germination and growth experiments using soil and litter collected beneath defoliated tamarisk trees. Focal species were two common native (red threeawn, sand dropseed) and two common …

Variability Of Particle Size Distributions In The Bohai Sea And The Yellow Sea, Zhongfeng Qui, Deyong Sun, Chuanmin Hu, Sengquiang Wang, Lufei Zheng, Yu Huang, Tian Peng

Marine Science Faculty Publications

Particle size distribution (PSD) is an important parameter that is relevant to many aspects of marine ecosystems, such as phytoplankton functional types, optical absorption and scattering from particulates, sediment fluxes, and carbon export. However, only a handful of studies have documented the PSD variability in different regions. Here, we investigate the PSD properties and variability in two shallow and semi-enclosed seas (the Bohai Sea (BS) and Yellow Sea (YS)), using in situ laser diffraction measurements (LISST-100X Type C) and other measurements at 79 stations in November 2013. The results show large variability in particle concentrations (in both volume and number …

Probing A Panoply Of Curvaton-Decay Scenarios Using Cmb Data, Tristan L. Smith, D. Grin

Physics & Astronomy Faculty Works

In the curvaton scenario, primordial curvature perturbations are produced by a second field that is subdominant during inflation. Depending on how the curvaton decays [possibly producing baryon number, lepton number, or cold dark matter (CDM)], mixtures of correlated isocurvature perturbations are produced, allowing the curvaton scenario to be tested using cosmic microwave background (CMB) data. Here, a full range of 27 curvaton-decay scenarios is compared with CMB data, placing limits on the curvaton fraction at decay, rD, and the lepton asymmetry, ξlep. If baryon number is generated by curvaton decay and CDM before (or vice versa), these limits imply specific …

Faculty Publications

We present results from a search for gravitational-wave bursts coincident with two core-collapse supernovae observed optically in 2007 and 2011. We employ data from the Laser Interferometer Gravitational-wave Observatory (LIGO), the Virgo gravitational-wave observatory, and the GEO 600 gravitational-wave observatory. The targeted core-collapse supernovae were selected on the basis of (1) proximity (within approximately 15 Mpc), (2) tightness of observational constraints on the time of core collapse that defines the gravitational-wave search window, and (3) coincident operation of at least two interferometers at the time of core collapse. We find no plausible gravitational-wave candidates. We present the probability of detecting …
