  1. 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...

  2. The Effect of Artificial Light on Wildlife Use of a Passage Structure

    Barriers to animal movement can isolate populations, impacting their genetic diversity, susceptibility to disease, and access to resources. Barriers to movement may be caused by artificial light, which is known...

  3. Arabic Diglossia Within Palestinian-Arab Folk Narratives

    The preservation of Palestinian folktales is a way to restore and preserve Palestinian culture in result to the declining state and displacement of Palestinian populations into other regions of the Arabic World...

  4. 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...

  5. 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...

  6. 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...

  7. A 3-D Analytical Model of a Halbach Axial Magnetic Coupling

    A 3-D analytical model is presented for a Halbach axial magnetic coupling. The field and torque are determined by first solving a 2-D field problem at the radial location in which the radial flux density is...

  8. Electrodynamic Wheel Magnetic Rolling Resistance

    In this paper the concept of magnetic rolling resistance (MRR) is introduced. The MRR is particularly useful when trying to characterize maglev devices that operate with a slip. Approaches to minimize the MRR...

  9. Designing a Continuously Variable Magnetic Gear

    This paper investigates the performance capabilities of a continuously variable magnetic gearbox that utilizes a flux focusing rotor structure. A fractional slot stator winding is designed to couple to the...

  10. Ideal Radial Permanent Magnet Coupling Torque Density Analysis

    This paper derives the closed form 3-D analytical torque equations for an ideal radial Halbach rotor magnetic coupling. The performance of the radial Halbach coupling is then compared with an ideal axial...
