    4 Wynnes Boating Manufacturing Company: A Market Analysis and Business Plan for Northwest Arkansas

    Get PDF
    This thesis focuses on a business plan for the opening and developing of a boat manufacturing company in Northwest Arkansas and, specifically, manufacturing of duck hunting boats. South Arkansas and Eastern Arkansas have boat-manufacturing companies, but none exist in Northwest Arkansas. Having developed an interest in duck hunting over the years, I have discovered a tremendous need to bring the boats to where a large portion of Arkansas population exists. The objective of this business is to identify the Northwest Arkansas market viability for a customized duck boat manufacturing company. This analysis and evaluation is meant to provide a business prospectus for a successful and long-term company

    Time dependent spin-dressing using a 3^3He atomic beam

    Full text link
    We have performed high precision experimental measurements of spin precession using a dressed 3^3He atomic beam. Spin-dressing uses an oscillating magnetic field detuned to high frequency which is orthogonal to a static magnetic field to effectively change the gyromagnetic ratio of a spin. We verify the validity of the spin-dressing Hamiltonian in regions beyond the limiting solution in which the Larmor frequency is much smaller than the frequency of the dressing field. We also evaluate the effect of magnetic field misalignment, e.g. if the oscillating magnetic field is not orthogonal to the static magnetic field. Modulation of the dressing field parameters is also discussed, with a focus on whether such a modulation can be approximated merely as a time dependent, dressed gyromagnetic ratio. Furthermore, we discuss implications for a proposed search for the neutron electric dipole moment, which would employ spin-dressing to make the effective 3^3He and neutron magnetic moments equal.Comment: 10 pages, 7 figure

    Towards musical interaction : 'Schismatics' for e-violin and computer.

    This paper discusses the evolution of the Max/MSP patch used in schismatics (2007, rev. 2010) for electric violin (Violectra) and computer, by composer Sam Hayden in collaboration with violinist Mieko Kanno. schismatics involves a standard performance paradigm of a fixed notated part for the e-violin with sonically unfixed live computer processing. Hayden was unsatisfied with the early version of the piece: the use of attack detection on the live e-violin playing to trigger stochastic processes led to an essentially reactive behaviour in the computer, resulting in a somewhat predictable one-toone sonic relationship between them. It demonstrated little internal relationship between the two beyond an initial e-violin ‘action’ causing a computer ‘event’. The revisions in 2010, enabled by an AHRC Practice-Led research award, aimed to achieve 1) a more interactive performance situation and 2) a subtler and more ‘musical’ relationship between live and processed sounds. This was realised through the introduction of sound analysis objects, in particular machine listening and learning techniques developed by Nick Collins. One aspect of the programming was the mapping of analysis data to synthesis parameters, enabling the computer transformations of the e-violin to be directly related to Kanno’s interpretation of the piece in performance

    Geomorphological similarity and uniqueness

    Get PDF
    Remote sensing technology, particularly the development of satellite imagery, has given geomorphology a valuable tool for the study of large area, regional landscapes. The small scale large area format of LANDSAT and other satellite imagery reduces the amount of detailed information provided for a given region. This can be an advantage for regional study as much of the local information that is filtered out tends to be detail which, while significant in small area studies, could mask regional patterns

    The Superhorizon Test of Future B-mode Experiments

    Full text link
    Inflation predicts B-mode polarization with correlations that span superhorizon scales at recombination. In contrast, the correlations set up by causal sources, such as phase transitions or defects, necessarily vanish on superhorizon scales. Motivated by BICEP2's B-mode detection, we consider the prospects for measuring the inflationary superhorizon signature in future observations. We explain that the finite resolution of an experiment and the filtering of the raw data induces a transfer of spurious subhorizon power to superhorizon scales, and describe ways to correct for it. We also provide a detailed treatment of possible sources of noise in the measurement. Finally, we present forecasts for the detectability of the signal with future CMB polarization experiments.Comment: 16 pages, 9 figures, 2 table

    Prediction techniques which can be or have been applied to subsonic rotors, and methods for designing helicopter rotors for reduced broadband noise generation are summarized. It is shown how detailed physical models of the noise source can be used to identify approaches to noise control

    Space processing of crystals for opto-electronic devices: The case for solution growth

    Get PDF
    The results obtained during a six month program aimed at determining the viability of space processing in the 1980's of dielectric-elastic-magnetic single crystals were described. The results of this program included: identification of some important emerging technologies dependent on dielectric-elastic-magnetic crystals, identification of the impact of intrinsic properties and defects in the single crystals on system performance, determination of a sensible common basis for the many crystals of this class, and identification of the benefits of micro-gravity and some initial experimental evidence that these benefits can be realized in space. It is concluded that advanced computers and optical communications are at a development stage for high demand of dielectric-elastic-magnetic single crystals in the mid-1980's. Their high unit cost and promise for significantly increased perfection by growth in space justified pursuit of space processing
