Daily Traffic Flow Forecasting Through a Contextual Convolutional Recurrent Neural Network Modeling Inter- and Intra-Day Traffic Patterns

IEEE transactions on intelligent transportation systems (Print), 2021
Traffic flow forecasting is an important problem for the successful deployment of intelligent transportation systems, which has been studied for more than two decades. In recent years, deep learning methods are emerging to serve as the benchmark tool for

Experimental investigation of flow patterns and external performance of a centrifugal pump that transports gas-liquid two-phase mixtures

International Journal of Heat and Fluid Flow, 2018
In order to reveal the mechanism of two-phase flow inside a centrifugal pump, visualization experiments were performed to investigate the gas-liquid two-phase flow patterns by using high-speed photography.

Flow Patterns, Transitions and Models for Specific Flow Patterns

2003
This chapter presents flow patterns, the configurations into which gas/liquid flows can arrange themselves in pipes and other geometries. Simple, mainly empirical, graphical methods for predicting the flow patterns occurring are then presented. The effect of flow patterns on heat transfer and of heat transfer on flow patterns are then considered ...

On Supersonic Flow Patterns

Journal of Applied Physics, 1949
For a definite Mach number, given by M2 = 4/(3−γ), all Mach lines in a steady plane two-dimensional potential flow of a perfect gas with expansion exponent γ have zero curvature. The use and significance of this relation are discussed, and the hypothetical expansion law consistent with straight Mach lines is deduced.

Adaptation to Incomplete Flow Patterns: No Evidence for ‘Filling-In’ the Perception of Flow Patterns

Perception, 1982
Inspecting a radial flow pattern reduced visual sensitivity to changes in the size of a test square of 0·5 deg side length when the square was accurately located at the point previously occupied by the focus of the adapting flow pattern. The effect was reduced by a third when there was a 1·0 deg diameter hole at the centre of the flow pattern, and ...

Inspiratory flow pattern in humans

Journal of Applied Physiology, 1984
The theoretical estimation of the mechanical work of breathing during inspiration at rest is based on the common assumption that the inspiratory airflow wave is a sine function of time. Different analytical studies have pointed out that from an energetic point of view a rectangular wave is more economical than a sine wave.

Pattern formation in flowing sand

Physical Review Letters, 1989
Using digital subtraction radiography, we study the basic modes of a granular material (here sand) flowing through a flat hopper. These modes take the form of density waves whose formation and propagation is controlled by several parameters, including the mass flow rate M and the hopper angle \ensuremath{\theta}.

Sensitivity to corners in flow patterns

Spatial Vision, 1987
Flow patterns are two-dimensional orientation structures that arise from the projection of certain kinds of surface coverings (such as fur) onto images. Detecting orientation changes within them is an important task, since the changes often correspond to significant events such as corners, occluding edges, or surface creases.

Two-Phase Flow Patterns and Flow Pattern Maps

1990
Abstract In gas-liquid flow the two phases can adopt various geometric configurations: these are known as flow patterns or flow regimes. Important physical parameters in determining the flow pattern are:
