Robustness, Flexibility, And Sensitivity In A Multifunctional Motor Control Model, David N. Lyttle, Jeffrey P. Gill, Peter J. Thomas, Hillel J. Chiel Dec 2016

Robustness, Flexibility, And Sensitivity In A Multifunctional Motor Control Model, David N. Lyttle, Jeffrey P. Gill, Peter J. Thomas, Hillel J. Chiel

Faculty Scholarship

Motor systems must adapt to perturbations and changing conditions both within and outside the body. We refer to the ability of a system to maintain performance despite perturbations as “robustness,” and the ability of a system to deploy alternative strategies that improve fitness as “flexibility.” Different classes of pattern-generating circuits yield dynamics with differential sensitivities to perturbations and parameter variation. Depending on the task and the type of perturbation, high sensitivity can either facilitate or hinder robustness and flexibility. Here we explore the role of multiple coexisting oscillatory modes and sensory feedback in allowing multiphasic motor pattern generation to be …

Regulating Secrecy, W. Nicholson Price Ii Dec 2016

Regulating Secrecy, W. Nicholson Price Ii

Articles

Inventors face a stark choice between two intellectual property systems of protecting innovative ideas: patents and trade secrecy. But accounts of this choice underexplore the role of the regulators that dominate some areas of innovation. Regulation interacts with intellectual property exclusivity in socially problematic ways by encouraging secrecy at the expense of innovation, efficiency, and competition. This Article theorizes how regulation empowers intellectual property generally, explains why this strengthening is problematic for trade secrecy but not for patents, and offers the solution of regulator-enforced disclosure. When a regulator defines a product or a process, it becomes much harder to successfully …

Moudi Analysis Of Particle Size Distributions For Ultrasonic Spraying Of Salt Solutions From An Array Of Microscopic Orifices, Yichen Sun, J. Mark Meacham Dec 2016

Moudi Analysis Of Particle Size Distributions For Ultrasonic Spraying Of Salt Solutions From An Array Of Microscopic Orifices, Yichen Sun, J. Mark Meacham

Mechanical Engineering and Materials Science Independent Study

We report characterization of spray-based nanoporous particle synthesis for use in the cathode of lithium-ion batteries. Ultrasonic Microarray Spray Tuning (uMIST) was used to create microdroplets of salt solutions and battery material precursors, and the size distributions of produced microdroplets were investigated with a MicroOrifice Uniform Deposit Impactor (MOUDI). Experimental challenges associated with spray orientation, flow control and consistency of operation were addressed, and a promising solution for continuous droplet collection to obtain a statistically relevant droplet size distribution was proposed. Improved analysis capabilities will lead to a better understanding of the uMIST droplet formation mechanism.

Computational Fluid Dynamics Analysis Of An Idealized Modern Wingsuit, Maria E. Ferguson, Ramesh K. Agarwal Dec 2016

Computational Fluid Dynamics Analysis Of An Idealized Modern Wingsuit, Maria E. Ferguson, Ramesh K. Agarwal

Mechanical Engineering and Materials Science Independent Study

The modern wingsuit has been the subject of few scientific studies to date, and the prevailing design process remains the dangerous “guess-and-check” method. This study employed the commercial flow solver ANSYS Fluent to solve the steady Reynolds Averaged Navier-Stokes equations with turbulence models. The computational fluid dynamics (CFD) results provided information on the flow about a wingsuit designed with an airfoil cross section and large planform. The CFD simulation was performed using the Spalart-Allmaras turbulence model for the 3D wingsuit case and the k‑kl‑ω Transition model for the 2D airfoil case. Although the lack of experimental data available on wingsuit …

Electrodeposition Of Boron Fiber, Michelle Heredia, Parag Banerjee Dec 2016

Electrodeposition Of Boron Fiber, Michelle Heredia, Parag Banerjee

Mechanical Engineering and Materials Science Independent Study

From previous experiments, it was determined that nickel was able to coat boron fiber, however this was done unevenly, with cracks characterizing the coating. This was where it was hypothesized that the boron fiber crossed the interface of the nickel electrolyte solution during electrodeposition. This was different than the coating at the middle, which was all under the electrolyte solution, and was characterized by a smoother surface. This experiment sought to find a way to coat the nickel across the boron fiber wire evenly. SEM images were taken at the top and at the middle of the fiber. An overview …

A Business Entity By Any Other Name: Corporation, Community And Kinship, Christian G. Vazquez Dec 2016

A Business Entity By Any Other Name: Corporation, Community And Kinship, Christian G. Vazquez

Alaska Law Review

Forty-five years ago, the Alaska Native Claims Settlement Act resolved outstanding land claims between the federal and state government and Alaska Natives. The fund created by the settlement was used as seed money to establish the Alaska Native Corporations. The Native corporations have particular features which make them distinct from other business entities, these differences have been lauded by some shareholders but have simultaneously drawn ire from others. In 2015 the Alaska legislature introduced H.B. 49, a benefit corporation bill that would allow entrepreneurs to pursue both profits and social ends. This note traces the rise of the modern Alaska …

Activity Preservation Of Plasmonic Biosensors With A Metal-Organic Framework, Lu Wang Dec 2016

Activity Preservation Of Plasmonic Biosensors With A Metal-Organic Framework, Lu Wang

McKelvey School of Engineering Graduate Student Theses & Dissertations

Antibody-antigen recognition enables antibody-conjugated nanostructures to serve as plasmonic biosensors with tunable specificity. However due to the instability of antibodies, these biosensors are susceptible to changes in the environment such as heat and aridity, leading to constraints on the transportation and handling of these sensors. Here we establish a method using a metal-organic framework crystal to preserve biosensor activity under severe environmental conditions, including exposure to high temperatures, an organic solvent and a proteolytic agent. After zeolitic imidazolate framework-8 (ZIF-8) crystals formed for 12 hours on a biosensor of gold nanorods conjugated with a model antibody, rabbit IgG, 80% of …

Undergraduate Sorority Students' Perceptions Of Current Body Size, Ideal Body Size, Eating Habits, And The Relation To Body Image Dissatisfaction, Julie Beiter Dec 2016

Undergraduate Sorority Students' Perceptions Of Current Body Size, Ideal Body Size, Eating Habits, And The Relation To Body Image Dissatisfaction, Julie Beiter

DNP and Student Works

Disordered eating patterns and body discontent are widespread in Western society, especially among young women. Many adopt the "thin ideal," a belief that women should have very slender bodies with small waists and minimal body fat. This body image is shaped by television, social media, and magazines. Research has shown that women who internalize the thin ideal are more likely to have concerns with body image dissatisfaction and disordered eating habits. The goal of the current descriptive correlational study was to examine relationships between perceived current body size, imagined ideal body size, actual body weight, eating patterns, and body satisfaction …

Materials Science and Engineering Faculty Research & Creative Works

GeSbS ridge waveguides have recently been demonstrated as a promising mid - infrared platform for integrated waveguide - based chemical sensing and photodetection. To date, their nonlinear optical properties remain relatively unexplored. In this paper, we characterize the nonlinear optical properties of GeSbS glasses, and show negligible nonlinear losses at 1.55 μm. Using self - phase modulation experiments, we characterize a waveguide nonlinear parameter of 7 W-1/m and nonlinear refractive index of 3.71 x 10-18 m2/W. GeSbS waveguides are used to generate supercontinuum from 1280 nm to 2120 nm at the -30 dB level. The spectrum expands along the red …

Chemical and Biochemical Engineering Faculty Research & Creative Works

Slight alterations in nanoparticles' surface properties can significantly influence the corona composition which may alter their interaction with the biological milieu. Size and porosity of silica nanoparticles (SNPs) are known to be predominant factors influencing their dose-dependent toxicity. Little is known however about the extent and type of protein adsorption on SNPs as a function of physicochemical properties and the role this might play on mechanisms of cellular uptake and toxicity. In this work we investigated the influence of size and porosity of SNPs on protein adsorption, cellular uptake, and toxicity in RAW 264.7 macrophages. Toxicity of the SNPs was …

Wave Motion Induced By Turbulent Shear Flows Over Growing Stokes Waves, Shahrdad Sajjadi, Serena Robertson, Rebecca Harvey, Mary Brown Dec 2016

Wave Motion Induced By Turbulent Shear Flows Over Growing Stokes Waves, Shahrdad Sajjadi, Serena Robertson, Rebecca Harvey, Mary Brown

Publications

The recent analytical of multi-layer analyses proposed by Sajjadi et al. (J Eng Math 84:73, 2014) (SHD14 therein) is solved numerically for atmospheric turbulent shear flows blowing over growing (or unsteady) Stokes (bimodal) water waves, of low-to-moderate steepness. For unsteady surface waves, the amplitude a(t)∝ekcita(t)∝ekcit, where kcikci is the wave growth factor, k is the wavenumber, and cici is the complex part of the wave phase speed, and thus, the waves begin to grow as more energy is transferred to them by the wind. This will then display the critical height to a point, where the thickness of the inner …

A Locomotion Control Algorithm For Robotic Linkage Systems, Jeffrey L. Dohner Dr. Dec 2016

A Locomotion Control Algorithm For Robotic Linkage Systems, Jeffrey L. Dohner Dr.

Electrical and Computer Engineering ETDs

This dissertation describes the development of a control algorithm that transitions a robotic linkage system between stabilized states producing responsive locomotion. The developed algorithm is demonstrated using a simple robotic construction consisting of a few links with actuation and sensing at each joint. Numerical and experimental validation is presented. In this algorithm, transitioning excitations, called rhythms, are formulated using terminal state control solutions. Rhythms are constrained to be low order parameterized functions allowing for the optimal control problem to be replaced by a parametric optimization problem with a limited set of easily solved unknowns. This algorithm is developed and demonstrated …

Evaluating Machine Learning Classifiers For Defensive Cyber Operations, Michael D. Rich, Robert F. Mills, Thomas E. Dube, Steven K. Rogers Dec 2016

Evaluating Machine Learning Classifiers For Defensive Cyber Operations, Michael D. Rich, Robert F. Mills, Thomas E. Dube, Steven K. Rogers

Military Cyber Affairs

Today’s defensive cyber sensors are dominated by signature-based analytical methods that require continuous maintenance and lack the ability to detect unknown threats. Anomaly detection offers the ability to detect unknown threats, but despite over 15 years of active research, the operationalization of anomaly detection and machine learning for Defensive Cyber Operations (DCO) is lagging. This article provides an introduction to machine learning concepts with a focus on the unique challenges to using machine learning for DCO. Traditional machine learning evaluation methods are challenged in favor of a value-focused evaluation method that incorporates evaluator-specific weights for classifier and sensitivity threshold selection …

A Case For Deception In The Defense, Spencer R. Calder Dec 2016

A Case For Deception In The Defense, Spencer R. Calder

Military Cyber Affairs

Cyber deception may be used fairly easily in a contested cyberspace to impose disproportionate operational cost to adversarial actors. Concepts of what comprise a legitimate defensive effort in cyberspace are changing. The concept of a rigid perimeter defense as a panacea are increasingly viewed as a fallacy. “Sovereign” cyberspaces are increasingly contested. Concurrently to these trends, the Department of Defense is moving toward standardization and homogenization of cyberspace that may facilitate enemy operation in our spaces. Military deception doctrine has been used successfully in conflict through the history of warfare in contested spaces and may provide a useful taxonomy to …

Leveraging Lexical Link Analysis (Lla) To Discover New Knowledge, Ying Zhao, Douglas J. Mackinnon, Shelley P. Gallup, Joseph L. Billingsley Dec 2016

Leveraging Lexical Link Analysis (Lla) To Discover New Knowledge, Ying Zhao, Douglas J. Mackinnon, Shelley P. Gallup, Joseph L. Billingsley

Military Cyber Affairs

Lexical Link Analysis (LLA) is a form of text mining in which word meanings represented in lexical terms (e.g., word pairs) are treated as if they are in a community of a word network. LLA can provide automated awareness for analyzing text data and reveal previously unknown, data-driven themed connections. We applied LLA to develop authentic archetypes and conversely determine potential imposters of that same archetype. We use publically available social media data to develop a cyber professional as an example. This paper reports the development of the algorithm, the collection and labeling of data, as well as the results …

Military Cyber Professionals Have An Important Part To Play In The Obama-Trump Transition, Michael V. Hayden Dec 2016

Military Cyber Professionals Have An Important Part To Play In The Obama-Trump Transition, Michael V. Hayden

Military Cyber Affairs

Over the course of decades in service, I have experienced multiple presidential transitions. Each new Commander in Chief updates policies, personnel, and priorities…especially when the transition involves a new political party. In this respect, the current transition from the Obama to the Trump administration is no different. While this periodic exercise of our democracy may seem disruptive to some, it is a true opportunity for military cyber professionals to help shape our future national security posture.

The Heart Of Vincentian Higher Education, Dennis H. Holtschneider Cm. Dec 2016

The Heart Of Vincentian Higher Education, Dennis H. Holtschneider Cm.

Journal of Vincentian Social Action

It means a great deal to me to be here at St. John’s University, where I began my university service twenty-seven years ago. It has been my own great joy to spend my life in Vincentian education. Working in Vincentian Universities combines my love for the intellectual life with a desire to serve the poor that I myself received because I attended a Vincentian university in my youth. And it’s the great heart of a Vincentian university to see possibility in ALL the young. I doubt that Bishop Loughlin, whose idea that there should be a university for immigrants led …

In English You Read With A Stopwatch: A Journey Towards Biliteracy In Two Older Adopted Salvadoran Children, Mary A. Petron, Barbara J. Greybeck

TAPESTRY

This longitudinal case study provides an in-depth exploration of the journey toward bilingualism and biliteracy of two older adopted Salvadoran siblings in U.S. schools. Data sources include observations in the home and school, interviews, written artifacts, field notes, and various reading test scores. Analysis suggests that literacy instruction in English tended to focus more on phonics and fluency than comprehension and vocabulary, and it assumed a level of oral proficiency in English that neither of the children had. Spanish literacy instruction was aimed toward children of Mexican origin that was neither culturally relevant nor geared toward their specific language needs. …

Security-Autonomy-Mobility Roadmaps: Passports To Security For Youth, Jeremy Schulz, Laura Robinson Dec 2016

Security-Autonomy-Mobility Roadmaps: Passports To Security For Youth, Jeremy Schulz, Laura Robinson

Sociology

Taking the highway along the California coast and swinging inland into one of the state's agricultural belts, the hills appear golden in the distance, spotted with gnarled oak trees. Vineyards rise up on either side of the highway, and occasionally cowboys may be seen in the distance herding grazing cattle. Yet as clouds of dust rise from the fields in this agricultural community, the idyllic scene fades dramatically in the town of Rancho Benito, a community wearing the signs of the hard economic times. This once relatively prosperous community is now a place in which many families sit down to …
