  1. A Flux-Focusing Cycloidal Magnetic Gearbox

    This paper investigates the performance of a -25:1 gear ratio cycloidal magnetic gearbox (CMG) with a flux-focusing rotor topology. The performance of the CMG is investigated by conducting an iterative...

  2. Using Landsat TM Imagery to Monitor Vegetation Change Following Flow Restoration to the Lower Owens River, California

    Rehabilitating river corridors to restore valuable riparian habitat consumes significant resources from both governments and private companies. Given these considerable expenditures, it is important to monitor...

  3. Frequency of Extra-Pair Paternity in Scissor-Tailed Flycatchers (Tyrannus forficatus) and Other Suboscines: Are Oscines and...

    Extra-pair paternity (EPP) appears to be widespread in passerine birds, but few studies have focused on suboscine species, and therefore it is unclear if this generalization can be extended to this group. In...

  4. Paternal Behaviour in a Socially Monogamous but Sexually Promiscuous Passerine Bird

    We documented parental behaviour and paternity of eastern kingbirds (Tyrannus tyrannus) to test the predictions that paternal care would decline with increasing loss of paternity, increasing nesting density (a...

  5. Demography of a Ground Nesting Bird in an Urban System: Are Populations Self-Sustaining?

    Urbanization poses threats to earth’s biota, and retention of remnant native habitat in protected areas within expanding urban boundaries may help alleviate threats to wildlife. However, it is unclear for...

  6. A Terrestrial-Aquatic Food Web Subsidy is Potentially Mediated by Multiple Predator Effects on an Arboreal Crab

    Terrestrial-aquatic food web subsidies are known to affect food web structure, ecosystem productivity, and stability of recipient habitats. This study describes a prey flux across the land–water interface...

  7. Spatial Patterns of Extra-pair Paternity for Spotted Towhees Pipilo Maculatus in Urban Parks

    The extra-pair (EP) mating system of birds may be influenced by food resources, such that nutritionally stressed females are unable to pursue EP fertilizations (constrained female hypothesis; CFH), or that...

  8. Improved Analytic Model for Eddy Current Force Considering Edge-effect of a Conductive Plate

    The eddy current induction in a conductive medium with finite width and thickness due to a moving magnetic rotor is studied. The presented formulation is based on the second order vector potential and the...

  9. A 3-D Analytic-Based Model of a Null-Flux Halbach Array Electrodynamic Suspension Device

    The purpose of this paper is to present the derivation of a 3-D analytical solution of a null-flux electrodynamic suspension device for a conductive plate. The device consists of a linear Halbach magnet array...

  10. A 3-D Analytical Model for a Double Halbach Linear Array Electrodynamic Suspension System

    By translationally moving a magnetic source above a conductive plate guideway both levitation and drag forces are created. Unfortunately, the electrodynamic drag force can be quite high [1]. Kratz studied a...
