(2011-08-08)A simple Richardson iteration procedure converges slowly when applied to thick, diffusive problems with scattering ratios near unity. The current state of the art for overcoming this is to use a Krylov method with a diffusion ...

(1978)This paper compares two methods of measuring the motion of a loudspeaker cone. An accelerometer device was built by designing and attaching a preamplifier to the piezoelectric crystal transducer assembly. This crystal has ...

(2019-01-10)Freeway loop ramps are the most restrictive common interchange ramp design, with sharp curves and low design speeds. Drivers utilizing these ramps can be forced to accelerate rapidly on entry ramps or decelerate rapidly ...

(2022-04-11)We develop, analyze, and test iterative methods for three kinds of multigroup transport problems: (1) k-eigenvalue neutronics, (2) thermal radiation transport, and (3) problems with “upscattering,” in which particles can ...

(2018-04-24)A nonlinear spatial multigrid algorithm was developed and explored as a technique to efficiently solve the nonlinear S2 acceleration equations for SN neutron transport calculations in 1-D slabs. Acceleration of the basic ...
