Power-Weighted Lpc Formant Estimation, Ruairí De Fréin

Conference papers

A power-weighted formant frequency estimation procedure based on Linear Predictive Coding (LPC) is presented. It works by pre-emphasizing the dominant spectral components of an input signal, which allows a subsequent estimation step to extract formant frequencies with greater accuracy. The accuracy of traditional LPC formant estimation is improved by this new power-weighted formant estimator for different classes of synthetic signals and for speech. Power-weighted LPC significantly and reliably outperforms LPC and variants of LPC at the task of formant estimation using the VTR formants dataset, a database consisting of the Vocal Tract Resonance (VTR) frequency trajectories obtained by human experts …

Predictive Model For Overall Network Security Risk, Nawa Raj Pokhrel, Chris P. Tsokos

USF Patents

A stochastic model is described for cybersecurity using a host access attack graph to determine network security risk. The model uses Markov chains in conjunction with vulnerability metrics to analyze risks associated with a number of different types of computing devices in various types of networks. The model can be used to identify critical nodes in a host access attack graph where attackers may be most likely to focus. Based on that information, a network administrator can make appropriate, prioritized decisions for system patching. Further, a flexible risk ranking technique is described, where the decisions made by an attacker can …

Advancing Functional Scientific Literacy To Socioscientific Literacy As A Cross Disciplinary Educational Goal: A Philosophical Analysis, Kory Bennett

USF Tampa Graduate Theses and Dissertations

Educational experiences built upon the Socioscientific Issues (SSI) framework provide opportunities for teachers and students to reflectively and reflexively address ill-defined complex scientific issues that affect human beings around the planet. Through the practice of Socioscientific Reasoning (SSR), while grappling with SSI, students have the potential to develop a SSI functional perspective of scientific literacy (SL); functional scientific literacy (FSL). Due to the multidimensional complexity of many human issues in and out of the science classroom, students are required to develop various skills, dispositions, and problem-solving strategies that expand from and connect with a SSI functional perspective of SL. The …

Wave Energy Extraction By Flexible Floaters, Simone Michele, Federica Buriani, Emiliano Renzi, Rooij M Van, Bayu Jayawardhana, Antonis I. Vakis

School of Engineering, Computing and Mathematics

We present a novel mathematical model to investigate the extraction of wave power by flexible floaters. The model is based on the method of dry modes, coupled with a matched eigenfunction expansion. Our model results compare satisfactorily with preliminary data obtained from a demonstrator device, developed at the University of Groningen. We show that the role of elasticity is to increase the number of resonant frequencies with respect to a rigid body, which has a positive effect on wave power output. The mathematical model is then extended to irregular incident waves, described by a JONSWAP spectrum. Our results show that …

Race And Ethnic Variation In College Students’ Allostatic Regulation Of Racism-Related Stress, Jacob E. Cheadle, Bridget J. Goosby, Joseph C. Jochman, Cara Tomaso, Chelsea B. Kozikowski Yancey, Timothy D. Nelson

Department of Sociology: Faculty Publications

Racism-related stress is thought to contribute to widespread race/ ethnic health inequities via negative emotion and allostatic stress process up-regulation. Although prior studies document racerelated stress and health correlations, due to methodological and technical limitations, they have been unable to directly test the stress-reactivity hypothesis in situ. Guided by theories of constructed emotion and allostasis, we developed a protocol using wearable sensors and daily surveys that allowed us to operationalize and time-couple self-reported racism-related experiences, negative emotions, and an independent biosignal of emotional arousal. We used data from 100 diverse young adults at a predominantly White college campus to assess …

Department of Mechanical and Materials Engineering: Faculty Publications

Non-healing wounds have placed an enormous stress on both patients and healthcare systems worldwide. Severe complications induced by these wounds can lead to limb amputation or even death and urgently require more effective treatments. Electrospun scaffolds have great potential for improving wound healing treatments by providing controlled drug delivery. Previously, we developed fibrous scaffolds from complex carbohydrate polymers [i.e. chitin-lignin (CL) gels]. However, their application was limited by solubility and undesirable burst drug release. Here, a coaxial electrospinning is applied to encapsulate the CL gels with polycaprolactone (PCL). Presence of a PCL shell layer thus provides longer shelf-life for the …

Modeling Biotic & Abiotic Drivers Affecting Biogeomorphic Coastal Foredunes, Bianca Charbonneau

Sustainability Seminar Series

Coastal dunes are exceptionally dynamic terrestrial habitats that will only grow increasingly vulnerable with climate change. A structured approach to protect and restore these and other coastal biogeomorphic interface habitats is needed to maintain their invaluable ecosystem services. Vegetation in these habitats acts as ecosystem engineers such that, to achieve this, one must understand and accurately forecast vegetation dynamics at the nexus of shifting abiotic conditions and drivers of change. We developed a process-based model for coastal dune vegetation ecology, specifically, growth, density, and colonization as it affects and is affected by shifting habitat topography and storm event impact. The …

Student Publications

Multi-layered metamaterial structures show promise in a wide variety of optical applications such as superlenses, electromagnetic cloaking, tunable filters, sensors, and spatial light modulators. Optical transmission analysis of multilayer metallo-dielectric stacks with overall thickness less than the wavelength of light can be modeled using effective medium theory and the Berreman matrix method. For multilayer anisotropic stacks of arbitrary thickness, a rigorous 4 × 4 transfer matrix embodiment is typically used. In this work, a 2 × 2 anisotropic transfer matrix method is developed to analyze optical propagation through multilayer uniaxial stacks of arbitrary thicknesses. Optical transmission of a multilayer silver–zinc …
