Behavior-Based Power Management In Autonomous Mobile Robots, Charles A. Fetzek

Theses and Dissertations

Current attempts to prolong the life of a robot on a single battery charge focus on lowering the operating frequency of the onboard hardware, or allowing devices to go to sleep during idle states. These techniques have much overhead and do not come built in to the underlying robotic architecture. In this thesis, battery life is greatly extended through development of a behavior-based power management system, including a Markov decision process power planner, thereby allowing future robots increased time to operate and loiter in their required domain. Behavior-based power management examines sensors needed by the currently active behavior set and …

Hesperiidae Of Rondônia, Brazil: Taxonomic Comments On ‘Night’ Skippers, With Descriptions Of New Genera And Species (Lepidoptera: Eudaminae), George T. Austin

Insecta Mundi

Nineteen species of crepuscular and perhaps nocturnal eudamine skippers (Lepidoptera: Hesperiidae) included in Evans’ (1952) group “D” genera Bungalotis Watson, Salatis Evans, Sarmientoia Berg, Dyscophellus Godman and Salvin, and Nascus Watson occur in the Cacaulândia area of central Rondônia, Brazil. Their relative abundance and phenology there are given. Taxonomic comments and comparisons with published information are made. Bungalotis lactos Evans, 1952, new status, is considered a species separate from Bungalotis borax Evans, 1952. New genera Nicephellus and Euriphellus are proposed for Eudamus nicephorus Hewitson, 1876, and Papilio euribates Stoll, 1782, respectively, removing both from Dyscophellus and creating new combinations. Discophellus …

Double-Stranded Rna-Activated Protein Kinase Pkr Of Fishes And Amphibians: Varying The Number Of Double-Stranded Rna Binding Domains And Lineage-Specific Duplications, Loubna Tazi, Stefan Rothenburg, Nikolaus Deigendesch, Madhusudan Dey, Thomas E. Dever

Faculty Publications

Double-stranded (ds) RNA, generated during viral infection, binds and activates the mammalian anti-viral protein kinase PKR, which phosphorylates the translation initiation factor eIF2alpha leading to the general inhibition of protein synthesis. Although PKR-like activity has been described in fish cells, the responsible enzymes eluded molecular characterization until the recent discovery of goldfish and zebrafish PKZ, which contain Z-DNA-binding domains instead of dsRNA-binding domains (dsRBDs). Fish and amphibian PKR genes have not been described so far. Results- Here we report the cloning and identification of 13 PKR genes from 8 teleost fish and amphibian species, including zebrafish, demonstrating the coexistence of …

The Murky Waters Of Non-Human Colonization: Carp, Bass And The Shifting Sands Of Lake Andes, South Dakota, David Nesheim

Department of History: Dissertations, Theses, and Student Research

In an effort to increase the food supply, the U.S. Fish Commission began shipping carp hatchlings in 1877 and within five years the number of requests grew to seven thousand. By 1896 the stocking program was discontinued when any further introductions were deemed unnecessary. It did not take long for the fish to overspread the continent, moving from the ranks of coveted transplant to invasive menace by the 1920s. From the first application in 1934, an active campaign of carp poisoning was underway in lakes and stream across the country by the 1950s. In 1958, the U.S. Fish and Wildlife …

Renin Inhibition Reduces Hypercholesterolemia-Induced Atherosclerosis In Mice, Hong Lu, Debra L. Rateri, David L. Feldman, Richard Charnigo, Akiyoshi Fukamizu, Junji Ishida, Elizabeth Grace Oesterling, Lisa A. Cassis, Alan Daugherty

Saha Cardiovascular Research Center Faculty Publications

The role of the renin angiotensin system (RAS) in atherosclerosis is complex because of the involvement of multiple peptides and receptors. Renin is the rate-limiting enzyme in the production of all angiotensin peptides. To determine the effects of renin inhibition on atherosclerosis, we administered the novel renin inhibitor aliskiren over a broad dose range to fat-fed LDL receptor-deficient (Ldlr^-/-) mice. Renin inhibition resulted in striking reductions of atherosclerotic lesion size in both the aortic arch and the root. Subsequent studies demonstrated that cultured macrophages expressed all components of the RAS. To determine the role of macrophage-derived angiotensin in …

Exploitation Of Self Organization In Uav Swarms For Optimization In Combat Environments, Dustin J. Nowak

Theses and Dissertations

This investigation focuses primarily on the development of effective target engagement for unmanned aerial vehicle (UAV) swarms using autonomous self-organized cooperative control. This development required the design of a new abstract UAV swarm control model which flows from an abstract Markov structure, a Partially Observable Markov Decision Process. Self-organization features, bio-inspired attack concepts, evolutionary computation (multi-objective genetic algorithms, differential evolution), and feedback from environmental awareness are instantiated within this model. The associated decomposition technique focuses on the iterative deconstruction of the problem domain state and dynamically building-up of self organizational rules as related to the problem domain environment. Resulting emergent …

Collision Avoidance For Uavs Using Optic Flow Measurement With Line Of Sight Rate Equalization And Looming, Paul J. Shelnutt

Theses and Dissertations

A series of simplified scenarios is investigated whereby an optical flow balancing guidance law is used to avoid obstacles by steering an air vehicle between fixed objects/obstacles. These obstacles are registered as specific points that can be representative of features in a scene. The obstacles appear in the field of view of a single forward looking camera. First a 2-D analysis is presented where the rate of the line of sight from the vehicle to each of the obstacles to be avoided is measured. The analysis proceeds by initially using no field of view (FOV) limitations, then applying FOV restrictions, …

Functions, Structure, And Read-Through Alternative Splicing Of Feline Apobec3 Genes, Carsten Munk, Thomas W. Beck, Jorg Zielonka, Agnes Hotz-Wagenblatt, Sarah Chareza, Marion Battenberg, Jens Thielebein, Klaus Cichutek, Ignacio G. Bravo, Stephen J. O'Brien, Martin Lochelt, Naoya Yuhki

Biology Faculty Articles

Background:

Over the past years a variety of host restriction genes have been identified in human and mammals that modulate retrovirus infectivity, replication, assembly, and/or cross-species transmission. Among these host-encoded restriction factors, the APOBEC3 (A3; apolipoprotein B mRNA-editing catalytic polypeptide 3) proteins are potent inhibitors of retroviruses and retrotransposons. While primates encode seven of these genes (A3A to A3H), rodents carry only a single A3 gene.

Results:

Here we identified and characterized several A3 genes in the genome of domestic cat (Felis catus) by analyzing the genomic A3 locus. The cat genome presents one A3H gene and three …

Opportunities For Spiritual Awakening And Growth In Mothering, Melissa J. Albee

USF Tampa Graduate Theses and Dissertations

My experiences as a mother have been enhanced by spirituality and my spirituality has been transformed through the practice of mothering. I will argue that part of the transformation available in mothering is that one can go from thinking of oneself as an individual with free will, self autonomy, and independence to believing maybe we are all more connected and dependent upon each other than we thought. I intend to explore my personal spiritual journey from an academic perspective in order to gain and share knowledge. Intense emotional experiences such as childbirth, learning how to take care of a person …

Conceptual Study Of Rotary-Wing Microrobotics, Kelson D. Chabak

Theses and Dissertations

This thesis presents a novel rotary-wing micro-electro-mechanical systems (MEMS) robot design. Two MEMS wing designs were designed, fabricated and tested including one that possesses features conducive to insect level aerodynamics. Two methods for fabricating an angled wing were also attempted with photoresist and CrystalBond™ to create an angle of attack. One particular design consisted of the wing designs mounted on a gear which are driven by MEMS actuators. MEMS comb drive actuators were analyzed, simulated and tested as a feasible drive system. The comb drive resonators were also designed orthogonally which successfully rotated a gear without wings. With wings attached …

A Potential Field Based Formation Control Methodology For Robot Swarms, Laura E. Barnes

USF Tampa Graduate Theses and Dissertations

A novel methodology is presented for organizing swarms of robots into a formation utilizing artificial potential fields generated from normal and sigmoid functions. These functions construct the surface which swarm members travel on, controlling the overall swarm geometry and the individual member spacing. Nonlinear limiting functions are defined to provide tighter swarm control by modifying and adjusting a set of control variables forcing the swarm to behave according to set constraints, formation and member spacing. The swarm function and limiting functions are combined to control swarm formation, orientation, and swarm movement as a whole. Parameters are chosen based on desired …
