Rheotaxis is a robust, multisensory behavior with many potential benefits for fish and other aquatic organisms. Visual (optic flow) cues appear to be sufficient for rheotaxis, but other sensory cues can clearly compensate for the loss of vision. Nevertheless, the nature of multisensory interactions and the relative contributions of different senses under varying conditions are poorly understood...

Abstract In recent years, fluidic oscillators have been actively applied as devices for flow control in the field of aero and hydrodynamics. This study aims to investigate structure a sweeping jet ejected from oscillator into confined area – slot channel. Dynamics are investigated using PIV method with high temporal resolution. The effect Re number on oscillation frequency was studied range 1 5...

We describe an approach to construct hexahedral solid NURBS (Non-Uniform Rational B-Splines) meshes for patient-specific vascular geometric models from imaging data for use in isogeometric analysis. First, image processing techniques, such as contrast enhancement, filtering, classification, and segmentation, are used to improve the quality of the input imaging data. Then, lumenal surfaces are e...

This experimental study investigates ten subjects playing the trombone in the lower and mid-high range of the instrument, B♭2 to F4. Several techniques are combined to show the pressures and the impedance spectra upstream and downstream of the lips, the acoustic and total flows into the instrument, the component of the acoustic flow due to the sweeping motion of the lips, and high speed video i...

The formation and evolution of volumetric flow structures from a rectangular orifice synthetic jet (AR=10, Re=550, Sr=0.0117, Lo=0.0855m) impinging on flat plate is investigated using phase-locked single-camera light-field particle image velocimetry (LF-PIV). An located 24 widths away the rectangle this data used to capture mechanisms involved in interaction. Flow statistics structure informati...

The Mine Sweeping System is being developed for the sole purpose of efficiently detecting mines within a user defined area .It comprises of a Java application from the user end and a robot grid system which work together to form a fully automated, optimized and efficient system. The Server (i.e. the application) and the Robots communicate with each other through wireless transmission and at no ...

unsteady flow through non - homogeneous and anisotropic porous media can be modeled by a partial differential equation.' this-equation cannot be solved analytically. hence, numerical methods. such as the finite element and the finite difference methods might be employed. in this study a mathematical model has been developed using the fully implicit finite difference method with control vol...
