Acceleration and motion-correction techniques for high-resolution intravascular MRI.

PURPOSE High-resolution intravascular (IV) MRI is susceptible to degradation from physiological motion and requires high frame-rates for true endoscopy. Traditional cardiac-gating techniques compromise efficiency by reducing the effective scan rate. Here we test whether compressed sensing (CS) reconstruction and ungated motion-compensation using projection shifting, could provide faster motion-...

Holkner. Acceleration Techniques for Busy Beaver Candidates ACCELERATION TECHNIQUES FOR BUSY BEAVER CANDIDATES

ABSTRACT: A busy beaver is a Turing machine of N states which, given a blank tape, halts with an equal or higher number of printed symbols than all other machines of N states. Candidates for this class of Turing machine cannot realistically be run on a traditional simulator due to their high demands on memory and time. This paper describes some techniques that can be used to run these machines ...

Acceleration Techniques for Newton's Non-linear Iterative Scheme Acceleration Techniques for Newton's Non-linear Iterative Scheme Acceleration Techniques for Newton's Non-linear Iterative Scheme

The solution of non-linear sets of algebraic equations is usually obtained by the Newton's method, exhibiting quadratic convergence. For practical simulations, a signiicant computational eeort consists in the evaluation of the Jacobian matrices. In this paper, we propose and experiment various methods to speed the convergence process either by re-using information from previous iterates or by b...

On Convergence Acceleration Techniques for Unstructured Meshes

A discussion of convergence acceleration techniques as they relate to computational fluid dynamics problems on unstructured meshes is given. Rather than providing a detailed description of particular methods, the various different building blocks of current solution techniques are discussed and examples of solution strategies using one or several of these ideas are given. Issues relating to uns...
