Bio-Inspired, Varying Manifold Based Method With Enhanced Initial Guess Strategies For Single Vehicle's Optimal Trajectory Planning, Ni Li

Electronic Theses and Dissertations

Trajectory planning is important in many applications involving unmanned aerial vehicles, underwater vehicles, spacecraft, and industrial manipulators. It is still a challenging task to rapidly find an optimal trajectory while taking into account dynamic and environmental constraints. In this dissertation, a unified, varying manifold based optimal trajectory planning method inspired by several predator-prey relationships is investigated to tackle this challenging problem. Biological species, such as hoverflies, ants, and bats, have developed many efficient hunting strategies. It is hypothesized that these types of predators only move along paths in a carefully selected manifold based on the prey’s motion in some of …

Evaluation Of The Biodegradability And Toxicity Of Pca And Mpca, Juan Rueda

Electronic Theses and Dissertations

The main types of hypergolic propellants used at Kennedy Space Center (KSC) are hydrazine (HZ) and monomethylhydrazine (MMH). HZ and MMH are classified as hazardous materials and they are also known to be potentially carcinogenic to humans; therefore, handling these substances and their waste is strictly regulated. The wastes streams from HZ and MMH have been estimated to be the main hazardous wastes streams at KSC. Currently at KSC these wastes are first neutralized using citric acid and then they are transported on public roads for incineration as hazardous materials. A new method using alpha ketoglutaric acid (AKGA) was proposed …

Virtual Interactions With Real-Agents For Sustainable Natural Resource Management, Tyler Pierce

Electronic Theses and Dissertations

Common pool resource management systems are complex to manage due to the absence of a clear understanding of the effects of users’ behavioral characteristics. Non-cooperative decision making based on individual rationality (as opposed to group rationality) and a tendency to free ride due to lack of trust and information about other users’ behavior creates externalities and can lead to tragedy of the commons without intervention by a regulator. Nevertheless, even regulatory institutions often fail to sustain natural common pool resources in the absence of clear understanding of the responses of multiple heterogeneous decision makers to different regulation schemes. While modeling …

Near-Road Dispersion Modeling Of Mobile Source Air Toxics (Msats) In Florida, Kurt Westerlund

Electronic Theses and Dissertations

There is a growing public concern that emissions of mobile source air toxics (MSATs) from motor vehicles may pose a threat to human health. At present, no state or federal agencies require dispersion modeling of these compounds, but many agencies are concerned about potential future requirements. Current air pollution professionals are familiar with Federal Highway Administration (FHWA) and U.S. Environmental Protection Agency (EPA) requirements for dispersion modeling to produce predicted concentrations for comparison with appropriate standards. This research examined a method in which the potential near-road concentrations of MSATs were calculated. It was believed that by assessing MSATs in much …

Automatically Acquiring A Semantic Network Of Related Concepts, Sean Szumlanski

Electronic Theses and Dissertations

We describe the automatic acquisition of a semantic network in which over 7,500 of the most frequently occurring nouns in the English language are linked to their semantically related concepts in the WordNet noun ontology. Relatedness between nouns is discovered automatically from lexical co-occurrence in Wikipedia texts using a novel adaptation of an information theoretic inspired measure. Our algorithm then capitalizes on salient sense clustering among these semantic associates to automatically disambiguate them to their corresponding WordNet noun senses (i.e., concepts). The resultant concept-to-concept associations, stemming from 7,593 target nouns, with 17,104 distinct senses among them, constitute a large-scale semantic …

Recognition Of Complex Events In Open-Source Web-Scale Videos: Features, Intermediate Representations And Their Temporal Interactions, Subhabrata Bhattacharya

Electronic Theses and Dissertations

Recognition of complex events in consumer uploaded Internet videos, captured under realworld settings, has emerged as a challenging area of research across both computer vision and multimedia community. In this dissertation, we present a systematic decomposition of complex events into hierarchical components and make an in-depth analysis of how existing research are being used to cater to various levels of this hierarchy and identify three key stages where we make novel contributions, keeping complex events in focus. These are listed as follows: (a) Extraction of novel semi-global features – firstly, we introduce a Lie-algebra based representation of dominant camera motion …

Examining The Physical And Mental Health Effects Of An Obesity Prevention Program In High Risk Adolescent Females: A Pilot Study, Luann K. Foster

Doctor of Psychology (PsyD)

Obesity is a growing concern in the United States as two-thirds of the population is clinically overweight or obese, a condition that carries with it a myriad of physical and mental health concerns. To address these concerns, many programs have been designed to incorporate evidence-based obesity prevention; however, few have addressed the needs of high risk middle school rural children. The current study examined the effectiveness of a specific obesity prevention program designed to decrease risk of obesity by helping female students increase daily physical activity to recommended levels. This program is designed to provide daily and weekly motivational incentives …

Nano-Particles In Multi-Scale Composites And Ballistic Applications, Jason Gibson

Electronic Theses and Dissertations

Carbon nanotubes, graphene and nano sized core shell rubber particles have all been extensively researched for their capability to improve mechanical properties of thermoset resins. However, there has been a lack of research on their evaluation for energy absorption in high velocity impact scenarios, and the fundamental mechanics of their failure mechanisms during highly dynamic stress transfer through the matrix. This fundamental research is essential for laying the foundation for improvement in ballistic performance in composite armor. In hard armor applications, energy absorption is largely accomplished through delamination between plies of the composite laminate. This energy absorption is accomplished through …

"Green" Product Procurement Policy In The European Union: Treatment Of Lifecycle Carbon Analysis And Environmental Ppm Restrictions, Shawna Ganley

Sabin Center for Climate Change Law

With approximately 19% of the EU’s GDP going to government purchases, “green procurement” policies could potentially have a sizable impact on carbon emissions, and moreover could bolster the larger consumer market for sustainable goods. This white paper reviews current EC policy in this area, focusing particularly on the way in which the EC treats lifecycle analysis and non-product related “process and production methods” (PPMs), criteria that relate to the way in which the product was produced rather than to the physical properties of the final product. The paper also addresses some of the factors that may have stymied better uptake …

Federalism, Liberty, And Risk In Nifb V. Sebelius, Aziz Huq

Public Law and Legal Theory Working Papers

This book chapter analyzes the Supreme Court’s decision in National Federation of Independent Business (NFIB) v. Sebelius. Contra conventional wisdom, it argues that the pivotal opinion of Chief Justice Roberts is not well explained in federalism terms. Rather, the decision is best understood in light of entrenched historical understandings of the federal government’s appropriate role in managing diverse species of risk.

Some Current Topics In Plant Domestication: An Overview With Particular Reference To Amazonia, Barbara Pickersgill

Tipití: Journal of the Society for the Anthropology of Lowland South America

Amazonia offers some striking contrasts to better-known regions of the world, notably the Middle East, in which plants were domesticated. These contrasts are pertinent to attempts to formulate general principles of evolution under domestication, particularly now that some of these are being critically reexamined. Topics covered in this paper include a generally applicable definition of plant domestication; how domestication may be recognised archaeobotanically; the relative roles of conscious and unconscious human selection; when and how rapidly domestication occurred; whether the same crop was domesticated more than once; and where a crop was domesticated. The archaeobotanical record for Amazonia and the …

Domestication Of Peach Palm In Southwestern Amazonia, Michelly De Cristo-Araújo, Vanessa Maciel Dos Reis, Doriane Picanço Rodrigues, Charles R. Clement

Tipití: Journal of the Society for the Anthropology of Lowland South America

The peach palm (Bactris gasipaes Kunth) is the only Neotropical palm domesticated by Native Americans. Its place of origin as a crop (B. gasipaes var. gasipaes) has been debated for more than a century, with three hypotheses currently in discussion: southwestern Amazonia; northwestern South America; or multiple origins in the distribution of the wild relatives (B. gasipaes var. chichagui). The small amount of archaeological data available supports the second hypothesis, but they contrast dramatically with the molecular-genetic analyses that support the first or the third, depending on how they are interpreted. On morphological grounds, two of the three types of …

The Social Production Of National Security, Aziz Huq

Public Law and Legal Theory Working Papers

This Article analyzes a recent policy innovation offered by governments on both sides of the Atlantic as a means of mitigating one form of national security risk: the idea that private individuals and voluntary associations have an untapped capacity for combating terrorism and in particular al Qaeda. Bold assertions in recent strategy statements mooting this possibility have wanted for any supporting account of how private behavior conduces to security. Even if the claimed social production of security against terrorism is causally well-founded, it is unclear how the state can elicit desirable private conduct. Consequently, the proposal’s legal and policy ramifications …

Forcings, Lee Anne Fennell

Public Law and Legal Theory Working Papers

Eminent domain receives enormous amounts of scholarly and popular attention, and for good reason—it is a powerful form of government coercion that cuts to the heart of ownership. But a mirror-image form of government coercion has been almost entirely ignored: forced ownership, or "forcings." While legal compulsion to begin or continue ownership is neither entirely unstudied as an academic matter nor entirely unprecedented as a doctrinal matter, the category lacks a unified treatment. Because coercively imposed ownership can substitute for other forms of government coercion, forcings deserve attention, even if they will rarely dominate other alternatives. Attending to forcings as …

Menthol Binding And Inhibition Of A7-Nicotinic Acetylcholine Receptors, Abrar Ashoor, Jacob C. Nordman, Daniel Veltri, Keun-Hang Susan Yang, Lina T. Al Kury, Yaroslav M. Shuba, Mohamed Magoub, Frank Christopher Howarth, Bassem Sadek, Amarda Shehu, Nadine Kabbani, Murat Oz

Menthol is a common compound in pharmaceutical and commercial products and a popular additive to cigarettes. The molecular targets of menthol remain poorly defined. In this study we show an effect of menthol on the α7 subunit of the nicotinic acetylcholine (nACh) receptor function. Using a two-electrode voltage-clamp technique, menthol was found to reversibly inhibit α7-nACh receptors heterologously expressed in Xenopus oocytes. Inhibition by menthol was not dependent on the membrane potential and did not involve endogenous Ca2+-dependent Cl− channels, since menthol inhibition remained unchanged by intracellular injection of the Ca2+ chelator BAPTA and perfusion with Ca2+-free bathing solution containing …

Critical Thinking: Primary Concepts, James Digiovanna

Open Educational Resources

I’ve been teaching critical thinking for many years, and I’ve developed a short, free, Creative Commons-licensed text that’s useful for a brief (maybe 3 week?) critical thinking section in any intro philosophy or composition course (or really, just about any course; it’s been used at my college by professors from a number of departments.)

A Philosophy Of Hope And A Landscape Of Principle: The Legacy Of David Getches's Federal Indian Law Scholarship, Rebecca Tsosie

University of Colorado Law Review

In this essay, Professor Tsosie documents two important aspects of David Getches's work in the field of federal Indian law. First, Professor Tsosie observes that David Getches was a strong proponent of guiding principles and a consistent structure in the law. Consequently, he was one of the first scholars to observe the ways in which the contemporary Supreme Court was "remapping" the field of federal Indian law, apparently in service of the Court's commitment to states' rights and the protection of mainstream values. David noted the dangers of this "subjectivist" approach and urged a return to the foundational principles of …

Jury Instructions As Constitutional Education, Andrew Guthrie Ferguson

University of Colorado Law Review

Juries are central to the constitutional structure of America. This Article articulates a theory of the jury as a "constitutional teaching moment," establishing a historical and theoretical basis for reclaiming the educative value of jury service. This Article addresses the fundamental question of why, despite an unquestioned acceptance of a constitutional role of the jury, our criminal justice system does not explain this role to jurors on jury duty. This Article seeks to answer the question of how we can educate jurors about the jury's constitutional role, while at the same time exploring the larger theoretical concerns with using the …

Renewable Energy Through Agency Action, Amy L. Stein

University of Colorado Law Review

Despite the many societal benefits associated with renewable energy, it is used to generate only about 5 percent of our nation's electricity needs. The bulk of governmental efforts to rectify this situation have disproportionately impacted private actors. This Article argues that the federal government should expand its efforts to more fully capture the gains that can be achieved by targeting both private and public actors, particularly federal agencies. Federal agencies have enormous purchasing power that can be channeled toward using electricity and fuels derived from renewable energy. Federal agencies are some of the largest consumers of electricity. Federal agencies manage …

I'Ll Huff And I'Ll Puff And I'Ll Blow Your House Down: The Argument For The Ability To Purchase Your Neighbor's Wind, Emily J. Wasserman

University of Colorado Law Review

Wind power capacity has increased substantially over the past decade. This growth in capacity is partially attributable to the policies that federal and state governments have enacted to help developers overcome the economic barriers to building commercial-scale wind facilities. However, the existing economic policies have a limited ability to continue to incentivize development of new wind power capacity. Therefore, if wind power capacity is going to continue to grow so that wind power eventually supplies enough electricity to meet a significant amount of the United States' energy needs, states need to supplement the economic policies with other, noneconomic policies. Specifically, …

Law Clinics And Lobbying Restrictions, Kevin Barry, Marcy Karin

University of Colorado Law Review

"Can law school clinics lobby?" This question has plagued professors for decades but has gone unanswered, until now. This Article situates law school clinics within the labyrinthine law of lobbying restrictions and concludes that clinics may indeed lobby. For ethical, pedagogical, and, ultimately, practical reasons, it is critical that professors who teach in clinics understand these restrictions. This Article offers advice to professors and students on safely navigating this complicated terrain.

Topical Gene Electrotransfer To The Epidermis Of Hairless Guinea Pig By Non-Invasive Multielectrode Array, Sigi Guo, Annelise L. Israel, Gaurav Basu, Amy Donate, Richard Heller

Bioelectrics Publications

Topical gene delivery to the epidermis has the potential to be an effective therapy for skin disorders, cutaneous cancers, vaccinations and systemic metabolic diseases. Previously, we reported on a non-invasive multielectrode array (MEA) that efficiently delivered plasmid DNA and enhanced expression to the skin of several animal models by in vivo gene electrotransfer. Here, we characterized plasmid DNA delivery with the MEA in a hairless guinea pig model, which has a similar histology and structure to human skin. Significant elevation of gene expression up to 4 logs was achieved with intradermal DNA administration followed by topical non-invasive skin gene electrotransfer. …

Bioelectrics In Basic Science And Medicine: Impact Of Electric Fields On Cellular Structures And Functions, Stephen J. Beebe

Bioelectrics Publications

Bioelectrics is a new interdisciplinary field that investigates electric field effects on cell membranes and other cellular components. It incorporates four main technologies, including electroporation, nanosecond pulsed electric fields, picosecond pulsed electric fields and cold plasmas. The parent technology in Bioelectrics is electroporation, which uses milli- and/or micro-second electric pulses to permeabilize cells and tissues, for delivery of membrane impermeable molecules. It is now being used for electro-gene delivery, with vascular endothelial growth factor, for revascularization in wound healing and cardiovascular and peripheral vascular disease. Plasmids expressing IL-12 are being delivered for immune system activation in melanoma treatment, now in …
