Autonomous Vehicle Technologies For Small Fixed-Wing Uavs, Randal Beard, Derek Kingston, Morgan Quigley, Deryl Snyder, Reed Christiansen, Walt Johnson, Timothy Mclain, Michael A. Goodrich Jan 2005

Autonomous Vehicle Technologies For Small Fixed-Wing Uavs, Randal Beard, Derek Kingston, Morgan Quigley, Deryl Snyder, Reed Christiansen, Walt Johnson, Timothy Mclain, Michael A. Goodrich

Faculty Publications

The objective of this paper is to describe the design and implementation of a small semi-autonomous fixed-wing unmanned air vehicle. In particular we describe the hardware and software architectures used in the design. We also describe a low weight, low cost autopilot developed at Brigham Young University and the algorithms associated with the autopilot. Novel PDA and voice interfaces to the UAV are described. In addition, we overview our approach to real-time path planning, trajectory generation, and trajectory tracking. The paper is augmented with movie files that demonstrate the functionality of the UAV and its control software.

Coordination Variables, Coordination Functions, And Cooperative Timing Missions, Randal Beard, Timothy W. Mclain Jan 2005

Coordination Variables, Coordination Functions, And Cooperative Timing Missions, Randal Beard, Timothy W. Mclain

Faculty Publications

Sponsorship: AFOSR, DARPA. This paper presents a solution strategy for achieving cooperative timing among teams of vehicles. Based on the notion of coordination variables and coordination functions, the strategy facilitates cooperative timing by requiring acceptably low levels of communication and computation. The application of the coordination variable/function approach to trajectory planning problems for teams of unmanned air vehicles with timing constraints is described. Three types of timing constraints are considered: simultaneous arrival, tight sequencing, and loose sequencing. Simulation results demonstrating the viability of the approach are presented.

Speech Interactions With Linguistic, Cognitive, And Visuomotor Tasks, Christopher Dromey, Emily Bates Jan 2005

Speech Interactions With Linguistic, Cognitive, And Visuomotor Tasks, Christopher Dromey, Emily Bates

Faculty Publications

Lip movements were examined across several repetitive speaking conditions (speech alone and speaking concurrently with a linguistic, cognitive, or visuomotor challenge task) in 20 young adults. Performance in these nonspeech activities was also compared between isolated tasks and concurrent speech conditions. Linguistic challenges resulted in increased spatiotemporal variability of lip displacement across repetitions. Motor challenges led to more rapid speech with smaller lip displacement. These qualitatively different changes suggest that different aspects of attention are required for linguistic versus manual visuomotor activity. Vocal intensity increased for all concurrent task conditions compared with speech alone, suggesting increased effort compared to the …

“Indian Participation In The Rocky Mountain Fur Trade.”, Jay H. Buckley Jan 2005

“Indian Participation In The Rocky Mountain Fur Trade.”, Jay H. Buckley

Faculty Publications

The Eastern Shoshones represent one of the most influential Indian groups in the histories of Wyoming and the Rocky Mountain fur trade. Before European contact their ancestral lands covered most of western Wyoming. After acquiring horses in the early eighteenth century, the eastern bands adopted the nomadic lifestyle and culture of the buffalo hunting Plains’ tribes. Leaving their lands between the Great Basin and Wind River Mountains, Shoshones ventured eastward via South Pass onto the plains to hunt bison. Th is expansion eastward brought contact with European traders offering horses, guns, and other manufactured goods that altered Shoshone life-ways and …

Dependability Auditing With Model Checking, Bonnie Anderson, James Hansen, Paul Benjamin Lowry Jan 2005

Dependability Auditing With Model Checking, Bonnie Anderson, James Hansen, Paul Benjamin Lowry

Faculty Publications

Model checking offers a methodology for determining whether a model satisfies a list of correctness requirements. We propose a theory of dependability auditing with model checking based on four principles: (1) The modeling process should be partitioned into computational components and behavioral components as an aid to system understanding; (2) The complex system will be abstracted to create a model; (3) A language must be available that can represent and evaluate states and processes that evolve over time; (4) Given an adequate model and temporal specifications, a model checker can verify whether or not the input model is a model …

Leadership, Collective Personality, And Performance, David A. Hofmann, Lisa Jones Christensen Jan 2005

Leadership, Collective Personality, And Performance, David A. Hofmann, Lisa Jones Christensen

Faculty Publications

By viewing behavior regularities at the individual and collective level as functionally isomorphic, a referent-shift compositional model for the Big 5 personality dimensions is developed. On the basis of this compositional model, a common measure of Big 5 personality at the individual level is applied to the collective as a whole. Within this framework, it is also hypothesized that leadership (i.e., transformational, transactional, and passive) would predict collective personality and that collective personality would be significantly related to collective performance. The results supported these hypotheses using a sample of franchised units. On the basis of recent research at the individual …

Beyond The 10/40 Window: When All You Thought You Had To Do Is Not Enough, Bruce Campbell Moyer Jan 2005

Beyond The 10/40 Window: When All You Thought You Had To Do Is Not Enough, Bruce Campbell Moyer

Faculty Publications

There is always a danger in being overly focused on a task. When this happens, we can fail to see other tasks or parallel tasks that are equally demanding. This paper focuses on some other “windows,” beyond the “10/40 Window,” that also call for serious attention, concerted prayer, specialized training, their own unique strategies, and a variety of personnel/gifts.

Dietary Isoflavones Alter Regulatory Behaviors, Metabolic Hormones And Neuroendocrine Function In Long-Evans Male Rats, Edwin D. Lephart, James P. Proter, Lihong H. Bu, Trent D. Lund, Kenneth Setchell, Gina Ramoz, William R. Crowley Dec 2004

Dietary Isoflavones Alter Regulatory Behaviors, Metabolic Hormones And Neuroendocrine Function In Long-Evans Male Rats, Edwin D. Lephart, James P. Proter, Lihong H. Bu, Trent D. Lund, Kenneth Setchell, Gina Ramoz, William R. Crowley

Faculty Publications

Phytoestrogens derived from soy foods (or isoflavones) have received prevalent usage due to their 'health benefits' of decreasing: a) age-related diseases, b) hormone-dependent cancers and c) postmenopausal symptoms. However, little is known about the influence of dietary phytoestrogens on regulatory behaviors, such as food and water intake, metabolic hormones and neuroendocrine parameters. This study examined important hormonal and metabolic health issues by testing the hypotheses that dietary soy-derived isoflavones influence: 1) body weight and adipose deposition, 2) food and water intake, 3) metabolic hormones (i.e., leptin, insulin, T3 and glucose levels), 4) brain neuropeptide Y (NPY) levels, 5) heat production …

The MEGA mission would enable a sensitive all-sky survey of the medium-energy γ-ray sky (0.3-50 MeV). This mission will bridge the huge sensitivity gap between the COMPTEL and OSSE experiments on the Compton Gamma Ray Observatory, the SPI and IBIS instruments on INTEGRAL and the visionary ACT mission. It will, among other things, serve to compile a much larger catalog of sources in this energy range, perform far deeper searches for supernovae, better measure the galactic continuum emission as well as identify the components of the cosmic diffuse emission. The large field of view will allow MEGA to continuously monitor …

Public Health Nursing Acceptance Of The 5 A’S Protocol For Prenatal Smoking Cessation, Jihong Liu Dec 2004

Public Health Nursing Acceptance Of The 5 A’S Protocol For Prenatal Smoking Cessation, Jihong Liu

Faculty Publications

Oregon’s efforts in tobacco cessation have historically focused on the general population and have depended on quit line services as the primary intervention. The Oregon Smoke Free Mothers and Babies Program (SFMB) was developed in 2002 to focus on public health nurses and prenatal care providers who work with high risk pregnant women. It seeks to increase smoking cessation among low income and other high risk pregnant women by disseminating the U.S. Public Health Service best practices, the 5 A’s (Ask, Advise, Assess, Assist, Arrange) tobacco brief intervention protocol, to public health nurses and prenatal care providers. Interventions included teaching …

Career Paths Of Eminent Researchers In Marriage And Family Therapy, Sarah R. Droubay, Thorana S. Nelson, Lee N. Johnson, Scott A. Ketring

Faculty Publications

The mental health field of marriage and family therapy (MFT) needs more MFT researchers and more research to validate and verify the effectiveness and efficacy of MFT for the treatment of various mental health and relational problems. Knowing more about how successful researchers have developed their careers would be useful in both inspiring and guiding young MFT researchers toward success. Three eminent researchers whose careers have focused on MFT (James Alexander, John Gottman, and Howard Liddle) and their publications served as the research sample. Research questions addressing types of research, research samples, research questions, therapy model development, funding, and paths …

Ultraviolet Extinction Properties In The Milky Way, Lynne A. Valencic, Geoffrey C. Clayton, Karl D. Gordon Dec 2004

Ultraviolet Extinction Properties In The Milky Way, Lynne A. Valencic, Geoffrey C. Clayton, Karl D. Gordon

Faculty Publications

We have assembled a homogeneous database of 417 ultraviolet (UV) extinction curves for reddened sight lines having International Ultraviolet Explorer spectra. We have combined these with optical and Two Micron All Sky Survey photometry, allowing estimates of the ratio of total-to-selective extinction, RV, for the entire sample. Fitzpatrick-Massa (FM) parameters have also been found for the entire sample. This is the largest study of parameterized UV extinction curves yet published, and it covers a wide range of environments, from dense molecular clouds to the diffuse interstellar medium, with extinctions AV ranging from 0.50 to 4.80. It is the first to …

'You'll Get Nothing Out Of It'? The Inquest, Police And Aboriginal Deaths In Colonial Queensland, Mark Finnane, Jonathan Richards Dec 2004

'You'll Get Nothing Out Of It'? The Inquest, Police And Aboriginal Deaths In Colonial Queensland, Mark Finnane, Jonathan Richards

Faculty Publications

Colonisation in Australia entailed the establishment of legal institutions, but very often lagging the extension of the boundaries of settlement. As a common-law institution of ancient lineage the inquest was an important means of exploring reasons for unexplained deaths, even leading to prosecutions. Yet the protections afforded by rule of law institutions were nugatory where they affected Aboriginal people in conflict with settler society, as shown in this study of the many inquiries in which deaths were attributed to the actions of the police in colonial Queensland.

On Shioda-Inose Structures Of One-Parameter Families Of K3 Surfaces, Ling Long Dec 2004

On Shioda-Inose Structures Of One-Parameter Families Of K3 Surfaces, Ling Long

Faculty Publications

We develop an algorithm to determine a one-parameter family of elliptic curves associated to a one-parameter family of K3 surfaces with generic Picard number 19 by a Shioda-Inose structure. The family of elliptic curves is determined up to an isomorphism and an isogeny. An application to a generalized congruence number problem is also discussed. © 2004 Elsevier Inc.

A resonance search has been made in the D*±p∓ invariant-mass spectrum with the ZEUS detector at HERA using an integrated luminosity of 126 pb-1. The decay channels D*+ -→ D0πs+ → (K -π+)πs+ and D*+ → D0πs+ → (K-π+π+π-) πs+ (and the corresponding antiparticle decays) were used to identify D*± mesons. No resonance structure was observed in the D*± p∓ mass spectrum from more than 60 000 reconstructed D*± mesons. The results are not compatible with a report of the H1 Collaboration of a charmed pentaquark, Θc0. © Springer-Verlag / Società Italiana di Fisica 2004.

Indirect Aggression On Screen: A Hidden Problem?, Sarah M. Coyne Dec 2004

Indirect Aggression On Screen: A Hidden Problem?, Sarah M. Coyne

Faculty Publications

Throughout history people have found violence and aggression entertaining. The Romans cheered in colossal arenas as gladiators were brutally murdered. In medieval England spectators applauded as knights fought each other in jousting tournaments. Shakespearean audiences were awed with bloody and violent conclusions of plays such as Macbeth, King Lear and Hamlet. Violence in entertainment today exists in a more accessible form, with over 60 per cent of television programs containing some form (Bushman & Anderson, 2001). Psychologists have studied the effects of viewing violence on television and in the movies for the last 50 years. Early studies were …

Neglected Taxonomy Of Rare Desert Fishes: Congruent Evidence For Two Species Of Leatherside Chub, Jerald B. Johnson, Thomas E. Dowling, Mark C. Belk Dec 2004

Neglected Taxonomy Of Rare Desert Fishes: Congruent Evidence For Two Species Of Leatherside Chub, Jerald B. Johnson, Thomas E. Dowling, Mark C. Belk

Faculty Publications

Conservation biologists rely heavily on taxonomy to set the scope for biological monitoring and recovery planning of rare or threatened species. Yet, taxonomic boundaries are seldom evaluated as falsifiable hypotheses that can be statistically tested. Here, we examine species boundaries in leatherside chub (Teleostei, Cyprinidae), an imperiled desert fish native to the Bonneville Basin and upper Snake River drainages of western North America. Recent molecular data hint that this fish could be composed of two distinct taxa that are geographically separated into northern and southern species. To formally test this hypothesis, we evaluated leatherside chub using several different categories of …

Kalman Consensus Strategies And Their Application To Cooperative Control, Randal Beard, Derek Kingston, Wei Ren Nov 2004

Kalman Consensus Strategies And Their Application To Cooperative Control, Randal Beard, Derek Kingston, Wei Ren

Faculty Publications

Sponsorship: AFOSR, NSF. In this paper, we propose discrete-time and continuous-time consensus update schemes motivated by the discrete-time and continuous-time Kalman filters. With certainty information encoded into each agent, the proposed consensus schemes explicitly account for relative confidence in the information that is communicated from each agent in the team. We show mild sufficient conditions under which consensus can be achieved using the proposed schemes in the presence of switching interaction topologies. The Kalman consensus scheme is shown to be input-to-state stable. We show how to exploit this fact in multi-agent cooperative control scenarios.

Coordination Variables And Consensus Building In Multiple Vehicle Systems, Tim Mclain Nov 2004

Coordination Variables And Consensus Building In Multiple Vehicle Systems, Tim Mclain

Faculty Publications

Much of the research focus in the cooperative control community has been on formation control problems. This focus may be due to the fact that the group control problem can be reduced to well-established single-agent control problems by employing a leader-follower type control strategy. For example, single-agent path planning and trajectory generation techniques can be employed for the leader, and conventional trajectory tracking strategies can be employed for the followers. Indeed, formation control problems are much like linear systems theory: we search where the light is the brightest. It can be argued that formation control problems are the simplest type …

The Decline Of Covenant In Early Christian Thought, Noel B. Reynolds Nov 2004

The Decline Of Covenant In Early Christian Thought, Noel B. Reynolds

Faculty Publications

While many LDS attempts to describe or explain the transformation of the Christian movement and its teachings in the early centuries in terms of an accommodation to Greek philosophy, this paper focuses on the first two Christian centuries and the early elimination of covenant thinking and practice that may have opened the door to Greek thought.

Stat 5 Activators Can Replace The Requirement Of Fbs In The Adipogenesis Of 3t3-L1 Cells, William C. Stewart, James E. Baugh, Z. Elizabeth Floyd, Jacqueline M. Stephens Nov 2004

Stat 5 Activators Can Replace The Requirement Of Fbs In The Adipogenesis Of 3t3-L1 Cells, William C. Stewart, James E. Baugh, Z. Elizabeth Floyd, Jacqueline M. Stephens

Faculty Publications

The 3T3-L1 cells differentiate into fat cells that have many properties of native adipocytes including: substantial lipid accumulation, insulin sensitivity, and the ability to secrete endocrine hormones. A substantial expense in using these cells is fetal bovine serum (FBS), a critical component of efficient adipogenesis. Our recent studies on STAT 5 proteins have revealed that these transcription factors are phosphorylated and translocate to the nucleus immediately after the initiation of differentiation. Studies by several other laboratories also suggest that STAT 5 proteins can have pro-adipogenic properties. Growth hormone (GH) and prolactin (PRL) are both potent activators of STAT 5A and …
