    • A fast MOSFET rf switch for low-field NMR and MRI 

      Nacher, Pierre-Jean; Kumaragamage, Sashika; Tastevin, Geneviève; Bidinosti, Christopher (Elsevier, 2019-11-02)
      TRansmit Array Spatial Encoding (TRASE) MRI uses trains of rf pulses alternately produced by distinct transmit coils. Commonly used coil switching involving PIN diodes is too slow for low- and ultra-lowfield MRI and would ...

    • Inside out: transforming images of lab-grown plants for machine learning applications in agriculture 

      Krosney, Alexander E.; Sotoodeh, Parsa; Henry, Christopher J.; Beck, Michael A.; Bidinosti, Christopher P. (Frontiers, 2023-07-06)
      Machine learning tasks often require a significant amount of training data for the resultant network to perform suitably for a given problem in any domain. In agriculture, dataset sizes are further limited by phenotypical ...

    • Leveraging Guided Backpropagation to Select Convolutional Neural Networks for Plant Classification 

      Mostafa, Sakib; Mondal, Debajyoti; Beck, Michael A.; Bidinosti, Christopher P.; Henry, Christopher J.; Stavness, Ian (2022-05-11)
      The development of state-of-the-art convolutional neural networks (CNN) has allowed researchers to perform plant classification tasks previously thought impossible and rely on human judgment. Researchers often develop ...

    • Magnetic diffusion, inductive shielding, and the Laplace transform 

      Krosney, Alexander E.; Lang, Michael; Weirathmueller, Jakob J.; Bidinosti, Christopher P. (American Institute of Physics (AIP) for the American Association of Physics Teachers, 2021-04-21)
      In the quasistatic limit, a time-varying magnetic field inside a conductor is governed by the diffusion equation. Despite the occurrence of this scenario in many popular physics demonstrations, the concept of magnetic ...

    • The metallic sphere in a uniform ac magnetic field: A simple and precise experiment for exploring eddy currents and non-destructive testing 

      Honke, Michael L.; Bidinosti, Christopher P. (American Association of Physics Teachers, 2018-06)
      We describe a very simple experiment that utilizes standard laboratory equipment to measure the electromagnetic response of a metallic sphere exposed to a uniform ac magnetic field. Measurements were made for a variety of ...

    • Passive magnetic shielding in static gradient fields 

      Bidinosti, C. P.; Martin, J. W. (American Institute of Physics, 2014)
      The effect of passive magnetic shielding on dc magnetic field gradients imposed by both external and internal sources is studied for two idealized shield models: concentric spherical and infinitely-long cylindrical shells ...
