  1. Modeling reactive rarefied systems using a novel quasi-particle Boltzmann solver

    … Quasi-Particle Simulation (QuiPS), a novel flow solver, such that it can adequately model the rarefied portion of an atmospheric reentry trajectory. Direct Simulation Monte Carlo (DSMC) is the conventional solver for such conditions, but struggles to resolve transient flows, trace species, and …

  2. Voxel-Level Absorbed Dose Calculations With A Deterministic Grid-Based Boltzmann Solver For Nuclear Medicine and The Clinical Value of Voxel-Level Calculations

    … acceptable time. The deterministic grid-based Boltzmann solver (GBBS) was recently applied to radiation oncology where it was reported as fast and accurate for both megavoltage photons and high dose rate nuclide-based photon brachytherapy.</p> <p>This dissertation had two goals. The first was …

  3. Hybrid-PIC modeling and electrostatic probe survey of Hall thrusters

    … are used for electrons, and a particle-tracking Boltzmann solver is used for the heavy species. The two solutions are linked by charge neutrality. A novel statistical approach to particle creation and tracking is employed which reduces computational time. To provide boundary conditions for the …

  4. The power spectrum and bispectrum of inflation and cosmic defects

    … spectra they produce with a modified Einstein-Boltzmann solver sourced by unequal time correlators from components of the energy-momentum tensor of the defects. We use these spectra together with CMB likelihoods to obtain constraints on the energy scales of formation of the cosmic defects, …

  6. The Major Histocompatibility Complex in Rabbits

    … maps were generated using the Adaptive Poisson-Boltzmann Solver (APBS), visualising charge distribution differences in the peptide binding clefts among species. Polymorphisms were traced in the peptide binding regions of classical MHC-II molecules (DP, DQ, DR) and non-classical MHC-II molecules …
