    Profiles of inflated surfaces

    Get PDF
    We study the shape of inflated surfaces introduced in \cite{B1} and \cite{P1}. More precisely, we analyze profiles of surfaces obtained by inflating a convex polyhedron, or more generally an almost everywhere flat surface, with a symmetry plane. We show that such profiles are in a one-parameter family of curves which we describe explicitly as the solutions of a certain differential equation.Comment: 13 pages, 2 figure

    Translations and dynamics

    Full text link
    We analyze the role played by local translational symmetry in the context of gauge theories of fundamental interactions. Translational connections and fields are introduced, with special attention being paid to their universal coupling to other variables, as well as to their contributions to field equations and to conserved quantities.Comment: 22 Revtex pages, no figures.

    Options for Funding Local Library Operations (including Collections) in New Mexico

    Get PDF
    A study of operating funding options for the 93 local libraries within the New Mexico State Library system, which includes public libraries run by municipalities, counties, non-profit organizations, and Native American tribes. With many libraries having experienced decreasing operating funds since 2007, the authors review several options for funding local library operations, including increased State Library assistance; increased use of GO bonds; increased funding from counties and municipalities; establishing library districts; establishing Quality of Life districts; and collaboration between libraries and arts or cultural organizations. The report is illustrated with tables and graphs; appendices include information on the New Mexico anti-donation clause, a graph with a model for a library district in New York, and references

    South Valley Incorporation Feasibility Study (revised)

    Get PDF
    Determining the financial feasibility of a South Valley municipality requires developing estimates of the revenues that might be raised, and this in turn requires a careful reading of NM statutes to see what the city may be entitled to and what authority it has under state law, as well as estimating the tax bases and the levels of activity against which fees and charges for services will be assessed. It is also critical to determine how much it will cost to provide various municipal services to the South Valley. This study focuses on the costs and revenues associated with operating a municipal government and with identifying and estimating recurring revenues that may be used to meet on-going expenditures

    The Economic Importance of the Arts & Cultural Industries in Bernalillo County (Revised). Part I: Quantification of Economic Impacts

    Get PDF
    The purpose of this study is to measure the economic impact of arts and cultural industries in Albuquerque and Bernalillo County. This research draws upon data from secondary data sources, including a comprehensive set of records of individual employers, and information gathered from primary investigation of the cultural content and revenue sources of nearly 400 businesses and institutions. This study also provides data on the impact of art and cultural activities on public finances, including the city, county and state. All measurements are for calendar year 2004

    Economic Impacts of the Anticipated Non-Accreditation of Bernalillo County Levees

    Get PDF
    The Albuquerque Metropolitan Arroyo Flood Control Authority (AMAFCA) contracted the UNM Bureau of Business and Economic Research (BBER) to estimate the economic impact resulting from levees in Bernalillo County losing FEMA accreditation. The levees are not expected to meet FEMAs post Hurricane Katrina standards. BBER estimates the increased cost of flood insurance for parcels located in the floodplain will likely average about 5.5millioninthefirstyearand5.5 million in the first year and 6.2 million a year thereafter. Part 1 of the study describes the current floodplain in Bernalillo County, calculates the net new floodplain, and estimates the increase in flood insurance costs in the new floodplain. Part 2 examines the impacts of development of the net new floodplain. Illustrated with color maps and tables.\u2

    Preliminary Analysis: Impacts of the $8.50 Minimum Wage on Santa Fe Businesses, Workers and the Santa Fe Economy (Revised)

    Get PDF
    This is the preliminary analysis of data relating to the impacts of the $8.50 minimum wage mandated by the Living Wage Ordinance on Santa Fe workers, businesses and the Santa Fe economy. The final report will include a more complete analysis of data collected under this first phase of the research project and a statistical analysis of microdata available after the beginning of 2006

    On globally non-trivial almost-commutative manifolds

    Get PDF
    Within the framework of Connes' noncommutative geometry, we define and study globally non-trivial (or topologically non-trivial) almost-commutative manifolds. In particular, we focus on those almost-commutative manifolds that lead to a description of a (classical) gauge theory on the underlying base manifold. Such an almost-commutative manifold is described in terms of a 'principal module', which we build from a principal fibre bundle and a finite spectral triple. We also define the purely algebraic notion of 'gauge modules', and show that this yields a proper subclass of the principal modules. We describe how a principal module leads to the description of a gauge theory, and we provide two basic yet illustrative examples.Comment: 34 pages, minor revision
