Level set methods and fast marching methods : evolving interfaces in computational geometry, fluid mechanics, computer vision, and materials science by James Albert Sethian( Book )

54 editions published between 1996 and 2010 in English and held by 704 WorldCat member libraries worldwide

"This book is an introduction to level set methods and fast marching methods, which are powerful numerical techniques for analyzing and computing interface motion in a host of settings. They rely on a fundamental shift in how one views moving boundaries, rethinking the natural geometric Lagrangian perspective and exchanging it for an Eulerian, initial value partial differential equation perspective. The resulting numerical techniques can be used to track three dimensional complex fronts that can develop sharp corners and change topology as they evolve." "This new edition of Professor Sethian's successful text includes the latest advances in fast marching methods and extends the original volume to cover new areas of application." "This book will be a useful resource for mathematicians, applied scientists, practicing engineers, computer graphic artists, and anyone interested in the evolution of boundaries and interfaces."--Jacket
Vortex methods and vortex motion by Karl E Gustafson( Book )

15 editions published between 1990 and 2007 in English and held by 248 WorldCat member libraries worldwide

Vortex methods have emerged as a new class of powerful numerical techniques to analyze and compute vortex motion. This book addresses the theoretical, numerical, computational, and physical aspects of vortex methods and vortex motion. Vortex phenomena in fluid flows and the experimental, theoretical, and numerical methods used to characterize them are discussed in reviews by leading experts. Extensive photographs and sample computer graphics are provided. The development of large vortex structure in fluid flow is responsible for some of the most fascinating aspects of fluid dynamics, such as mixing, shearing, transport, and instability. Such issues arise in a variety of flow regimes, ranging from fundamental mathematical questions in laminar, transitional, and turbulent flow to sophisticated engineering settings and devices
Fronts propagating with curvature dependent speed : algorithms based on Hamilton-Jacobi formulations by Stanley Osher( Book )

An analysis of flame propagation by James Albert Sethian( Book )

4 editions published in 1982 in English and held by 7 WorldCat member libraries worldwide

We develop a mathematical theory of flame propagation and analyze the stability of a flame front. We consider a premixed, combustible fluid and model the front between the burnt and unburnt regions as an infinitely thin curve propagating in a direction normal to itself at a constant speed. We assume that the specific volume of a fluid particle increases by a fixed amount when it burns
Wave breaking over sloping beaches using a coupled boundary integral-level set method( )

1 edition published in 2003 in English and held by 5 WorldCat member libraries worldwide

We present a numerical method for tracking breaking waves over sloping beaches. We use a fully non-linear potential model for in-compressible, irrotational and inviscid flow, and consider the effects of beach topography on breaking waves. The algorithm uses a Boundary Element Method (BEM) to compute the velocity at the interface, coupled to a Narrow Band Level Set Method to track the evolving air/water interface, and an associated extension equation to update the velocity potential both on and off the interface. The formulation of the algorithm is applicable to two and three dimensional breaking waves; in this paper, we concentrate on two-dimensional results showing wave breaking and rollup, and perform numerical convergence studies and comparison with previous techniques
Programming direct N-body solvers on Connection Machines by Adam Greenberg( Book )

1 edition published in 1992 in English and held by 1 WorldCat member library worldwide

Abstract: "We analyze various ways to program a simple direct N- body solver on the Connection Machine CM-2 and CM-5, using both CM Fortran and CMMD Message Passion."
Two-dimensional, viscous, incompressible flow in complex geometries on a massively parallel processor( Book )

1 edition published in 1990 in English and held by 1 WorldCat member library worldwide

The efficient execution of this method on the Connection Machine results from a parallel N-body solver, parallel elliptic solvers, and a parallel data structure for the adaptive creation of computational elements on the boundary of the confining region. Using this method, we analyze the generation of large vortex structures, mixing, and shedding under various flow geometries and inlet/outlet profiles. The data from our simulations are visualized using the real-time flow visualization environment developed on the Connection Machine."

Nanosurveyor a framework for real-time data processing by Benedikt J Daurer( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Background: The ever improving brightness of accelerator based sources is enabling novel observations and discov-eries with faster frame rates, larger fields of view, higher resolution, and higher dimensionality. Results: Here we present an integrated software/algorithmic framework designed to capitalize on high-throughput experiments through efficient kernels, load-balanced workflows, which are scalable in design. We describe the streamlined processing pipeline of ptychography data analysis. Conclusions: The pipeline provides throughput, compression, and resolution as well as rapid feedback to the micro-scope operators
A unified approach to noise removal image enhancement, and shape recovery by Ravikanth Malladi( )

1 edition published in 1996 in English and held by 1 WorldCat member library worldwide

Fast Voronoi Diagrams and Offsets on Triangulated Surfaces( Book )

1 edition published in 2000 in English and held by 1 WorldCat member library worldwide

We apply the Fast Marching Method on triangulated domains to efficiently compute Voronoi diagrams and offset curves on triangulated manifolds. The computational complexity of the proposed algorithm is optimal, O(M log M), where M is the number of vertices. The algorithm also applies to weighted domains in which a different cost is assigned to each surface point
SHARP: a distributed GPU-based ptychographic solver( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Abstract : The SHARP framework provides fast images from high-throughput ptychographic datasets and a corner stone for demanding higher-dimensional analysis such as spectro-ptychography or tomo-ptychography. Abstract : Ever brighter light sources, fast parallel detectors and advances in phase retrieval methods have made ptychography a practical and popular imaging technique. Compared to previous techniques, ptychography provides superior robustness and resolution at the expense of more advanced and time-consuming data analysis. By taking advantage of massively parallel architectures, high-throughput processing can expedite this analysis and provide microscopists with immediate feedback. These advances allow real-time imaging at wavelength-limited resolution, coupled with a large field of view. This article describes a set of algorithmic and computational methodologies used at the Advanced Light Source and US Department of Energy light sources. These are packaged as a CUDA-based software environment named SHARP (http://camera.lbl.gov/sharp), aimed at providing state-of-the-art high-throughput ptychography reconstructions for the coming era of diffraction-limited light sources
