Compression and noise reduction of field maps

open access: yesPhysical Review Accelerators and Beams, 2018
Errors from discretization and large data volume of field maps is a concern for beam dynamics simulations with respect to achievable accuracy and to the required amount of time.

Uniformly continuous 1-1 functions on ordered fields not mapping interior to interior [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2008
In an earlier work we showed that for ordered fields F not isomorphic to the reals R, there are continuous 1-1 unctions on [0, 1]F which map some interior point to a boundary point of the image (and so are not open).

Plasma Equilibrium inside Various Cross-Section Capillary Discharges

open access: yes, 2017
Plasma properties inside a hydrogen-filled capillary discharge waveguide were modeled with dissipative magnetohydrodynamic simulations to enable analysis of capillaries of circular and square cross-sections implying that square capillaries can be used to

A Fast Map Merging Algorithm in the Field of Multirobot SLAM

open access: yesThe Scientific World Journal, 2013
In recent years, the research on single-robot simultaneous localization and mapping (SLAM) has made a great success. However, multirobot SLAM faces many challenging problems, including unknown robot poses, unshared map, and unstable communication.

Magnetic properties of materials for MR engineering, micro-MR and beyond

open access: yes, 2014
We present the results of a systematic measurement of the magnetic susceptibility of small material samples in a 9.4 T MRI scanner. We measured many of the most widely used materials in MR engineering and MR micro technology, including various polymers ...
