Visualizing vortex clusters in the wake of a high-speed train

2017 IEEE International Conference on Systems, Man, and Cybernetics (SMC), 2017
Visualization of fluid flows at a high-Reynoldsnumber (Re ~ 10 5 ) presents difficulties for user comprehensiondue to density and ambiguous interactions between vortices. Priorwork has used cluster-based reduced-order modelling (CROM) toanalyze the wake of a High-Speed Train (HST) with Re = 86,000.In this paper, we present a novel surface visualization

Visual machinery surveillance for high-speed periodic operations

2011 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2011
Abnormal behavior detection in periodic operations and high-frame-rate (HFR) video logging were realized by introducing a visual machinery surveillance algorithm, which includes a phase-encoding process for periodic operations to match input images with pre-stored reference images efficiently.

High Speed Recurrent Regression Network for Visual Tracking

2019 IEEE International Conference on Multimedia and Expo (ICME), 2019
For some recently released trackers, the spatial-temporal information of the target are processed separately, which is time consuming and inefficient for locating the target in the sequential data—videos. To solve this problem, we present a recurrent regression framework(RRNet), which leverages spatial and temporal information coherence on feature ...

High speed grasping using visual and force feedback

Proceedings 1999 IEEE International Conference on Robotics and Automation (Cat. No.99CH36288C), 2003
In most conventional manipulation systems, changes in the environment cannot be observed in real time because the vision sensor is too slow. As a result the system is powerless under dynamic changes or sudden accidents. To solve this problem we have developed a grasping system using high-speed visual and force feedback.

A Hierarchical Control Architecture for High-Speed Visual Servoing

The International Journal of Robotics Research, 2003
The efferent signal is the impulses from the brain to muscle or organ tissue. The afferent signal is the sensation that transmits the state of peripheral body parts to the brain. The motor control architectures of biological systems have hierarchical structures in which the efferent/afferent signals interact.

High-speed visual estimation using preattentive processing

ACM Transactions on Computer-Human Interaction, 1996
A new method is presented for performing rapid and accurate numerical estimation. The method is derived from an area of human cognitive psychology called preattentive processing. Preattentive processing refers to an initial organization of the visual field based on cognitive operations believed to be rapid, automatic, and spatially parallel.

High Speed Flow Visualization at HEG

2004
The High Enthalpy Shock Tunnel Gottingen (HEG) of the German Aerospace Center (DLR) is one of the largest free piston driven shock tunnels capable of simulating high temperature effects in re-entry flows. Full utilization of such a ground based high enthalpy impulse facility, with typical test times in the order of a few milliseconds, requires detailed

Visualization of high-speed interaction of bodies in water

AIP Conference Proceedings, 2016
The work presents opportunities of hydroballistic complex for studying the characteristics of movement super-cavitation model (SCM) on the length of waterway to 10 m. Gunfire of SCM implemented by this complex allows to study movement and collision of the different masses of SCM with underwater obstacles at subsonic, transonic and supersonic velocities

Computation and flow visualization in high-speed aerodynamics

Journal of Turbulence, 2005
This paper relates to numerical simulations and flow visualizations of internal and external high-speed aerodynamics. Fully compressible Navier–Stokes solvers using high-order shock-capturing schemes and turbulence models are developed for solving gas-dynamics problems.
