Introducing Flow Field Forecasting

2011 10th International Conference on Machine Learning and Applications and Workshops, 2011
A machine learning methodology, called flow field forecasting, is proposed for statistically predicting the future of a univariate time series. Flow field forecasting draws information from the interpolated flow field of an observed time series to build a forecast step-by-step.

Flow field-flow fractionation: Critical overview

Journal of Chromatography A, 2013
This overview regards some critical issues in performing flow field-flow fractionation (flow FFF, FlFFF, AF4, HF-FlFFF, HF5). It includes the channel thickness, void time, channel-flow parabolic profile, channel-flow velocity gradient, uniformity of the cross-flow, sample injection time, relaxation/focusing time, width of sample starting zone ...

NUMERICAL FLOW FIELD VISUALIZATION

Computers & Structures, 1988
The application of computer-generated imagery to analyze numerical solutions of fluid flow is presented. High-performance graphics workstations, their current capabilities, and their use in flow field analysis are discussed. Interactive flow field computations about complex three-dimensional bodies applying computer-generated imagery are projected for ...

The structure of the optic flow field

1998
The optic flow field is defined as preserving the intensity along flow-lines. Due to singularities in the image at fixed time, poles are created in the optic flow field. In this paper we describe the generic types of flow singularities and their generic interaction over time.

Flow Field of a Flame in a Channel

The Physics of Fluids, 1959
A stationary flame is stabilized in a two-dimensional channel in such a way that it closely corresponds to the case of a flame propagating in a channel. The entire flow field of unburned and burned gases is mapped by taking stroboscopic photographs of small particles suspended in the combustible gases.

Field-flow fractionation of macromolecules

Journal of Chromatography A, 1989
Field-flow fractionation (FFF) is a versatile family of techniques, applicable to macromolecules, colloids, and cell-sized particles. This paper focuses specifically on the applicability of FFF to macromolecules. Following a brief description of the principles of FFF, the characteristics of FFF that bear on its efficacy in separating macromolecules are

Lattice-based flow field modeling

IEEE Transactions on Visualization and Computer Graphics, 2004
We present an approach for simulating the natural dynamics that emerge from the interaction between a flow field and immersed objects. We model the flow field using the Lattice Boltzmann Model (LBM) with boundary conditions appropriate for moving objects and accelerate the computation on commodity graphics hardware (GPU) to achieve real-time ...

Voronoi Diagram in the Flow Field

2003
A new concept called a boat-sail distance is introduced on the surface of water with flow, and it is used to define a generalized Voronoi diagram, in such a way that the water surface is partitioned into regions belonging to the nearest harbors with respect to this distance.

Micro-Thermal Field-Flow Fractionation

Collection of Czechoslovak Chemical Communications, 2002
The effect of miniaturization of the separation channel on the performance of thermal field-flow fractionation (TFFF) is substantiated theoretically. The experiments carried out under carefully chosen experimental conditions proved the high performance of the separation of polymers within an extended range of molar masses from relatively low up to ...
