Visual bridgingof empty gaps in the optic flow [PDF]
Perception & Psychophysics, 1998 This is a study of perception of bending motion and jointed rigid motions over large invisible segments of a bending line. In this project, we investigated the visual perception of changing form of lines, built up by a series of dots and presented under highly reduced pictorial conditions.

A Numerical study for the efficacy of flow injection on the diminution of rudder cavitation
International Journal of Naval Architecture and Ocean Engineering, 2010 The complete avoidance of cavitation, as a result of gap flow between the fixed and movable portion of a horn type rudder system, is difficult. To reduce gap flow, it is a common practice to attach a half round prismatic bar that protrudes beyond the ...

SurVAE Flows: Surjections to Bridge the Gap between VAEs and Flows
CoRR, 2020 Normalizing flows and variational autoencoders are powerful generative models that can represent complicated density functions. However, they both impose constraints on the models: Normalizing flows use bijective transformations to model densities whereas VAEs learn stochastic transformations that are non-invertible and thus typically do not provide ...

Gas Flow across Gaps in Protoplanetary Disks [PDF]
The Astrophysical Journal, 2006 We analyze the gas accretion flow through a planet-produced gap in a protoplanetary disk. We adopt the alpha disk model and ignore effects of planetary migration. We develop a semi-analytic, one-dimensional model that accounts for the effects of the planet as a mass sink and also carry out two-dimensional hydrodynamical simulations of a planet embedded

Research on Taylor Vortex and Heat Transfer in AxialRadial Cooling Motor
Journal of Harbin University of Science and Technology, 2019 The analysis of flow and transfer of heat in the air gap of synchronous motor associated with axial-radial ventilation system is important due to the complexity of flow of cooling air in the air gap between rotor and stator.

Design of Thin‐Gap Channel Flow Cells [PDF]
Journal of The Electrochemical Society, 1987 A model for predicting the current, concentration, and potential distributions in a thin-gap channel flow is presented. The model does not invoke the thin diffusion layer assumption or the assumption of straight current lines, and it allows for multiple reactions.

Fractal and Fractional, 2023 Axial-flow turbomachinery is widely used in low head water transfer and electricity generation projects. As there is a gap between the impeller and casing of the tubular flow unit, the fluid will cross the gap to form tip leakage flow, which may induce ...

Analytical Calculation of Annular Gap Throttling of Damping Valve [PDF]
MATEC Web of Conferences, 2020 For the throttling characteristics of the suspension system damping valve, an analytical method for gap throttling based on turbulent flow state was proposed for the first time. The boundary layer theory was used to give the expression of the three-layer
