This paper describes a method for recognizing and measuring the motion of each individual leukocyte in microvessels from a sequence of images. A spatiotemporal image is generated whose spatial axes are parallel and vertical to vessel region contours. In order to enhance and extract only leukocyte traces with a tuned velocity range even under noisy background, we use a combination of a ltering p...

Infants develop phonetic categories by simply being exposed to adult speech. It remains unclear, however, how they handle the extensive variability inherent to speech, and how they process multiple linguistic functions that share the same acoustic parameters. Across four neural network simulations of lexical tone acquisition, self-organizing maps were trained with continuous speech input of inc...

This paper introduces ProsodyPro — A software tool for facilitating large-scale analysis of speech prosody, especially for experimental data. The program allows users to perform systematic analysis of large amounts of data and generates a rich set of output, including both continuous data like timenormalized F0 contours and F0 velocity profiles suitable for graphical analysis, and discrete meas...

We summarise recent results form direct numerical simulations of both non-rotating helically forced and rotating convection driven MHD equations in spherical wedge-shape domains. In the former, using perfect-conductor boundary conditions along the latitudinal boundaries we observe oscillations, polarity reversals and equatorward migration of the large-scale magnetic fields. In the latter we obt...

Vertical axis wind turbine (VAWT) blades undergo dynamic separation due to the large angle of attack variation they experience during a turbine rotation. The flow over a single blade was modeled using a sinusoidally pitching and surging airfoil in a constant free stream flow at a mean chord Reynolds number of 10. Two-dimensional, time resolved velocity fields were acquired using particle image ...

when flow passes over the tube bundles, energy of flow transfers to the tubes. the fluid induced vibrations (fiv) imposed on the tubes is one of the important problems in analyzing the tube bundles and causes several problems. in this work, first, laminar flow around circular cylinder asymmetrically in a channel is simulated. the reynolds number is 20 and 100. the lift forces to tube are not ze...

Note: the phenomena described in this chapter are very difficult to understand without viewing the moving stimuli. The reader is urged to view the demos when reading the chapter, at: 2 Like many aspects of vision, motion perception begins with a massive array of local measurements performed by neurons in area V1. Each receptive field covers a small piece of the visual world, and as a result suf...

We extend a family of high-resolution, semidiscrete central schemes for hyperbolic systems of conservation laws to three-space dimensions. Details of the schemes, their implementation, and properties are presented together with results from several prototypical applications of hyperbolic conservation laws including a nonlinear scalar equation, the Euler equations of gas dynamics, and the ideal ...
