Breakup of electrified jets is important in applications as diverse as electrospraying, electroseparations and electrospray mass spectrometry. Breakup of a perfectly conducting, incompressible Newtonian liquid jet surrounded by a passive insulating gas that is stressed by a radial electric field is studied by a temporal analysis. An initially quiescent jet is subjected to axially periodic shape...

On wall-size displays with pen or touch input, users can have difficulties reaching display contents located too high, too low, or too far away. Drag-and-drop interactions can be further complicated by bezels separating individual display units. Researchers have proposed a variety of interaction techniques to address this issue, such as extending the user’s reach (e.g., push-andthrow) and bring...

3D Confocal Scanning Laser Microscopy to Quantify Contact Angles in Natural Oil-Water Mixtures — The contact angle of a liquid drop on a solid surface is one of the most simple, useful and sensitive parameters in the hydraulic sciences to quantify and to qualify the wettability and the surface energy of different materials. In this paper, a confocal scanning laser microscope (CSLM) has been use...

in the present study, the nonlinear model of non-newtonian blood flow in cosine-shape stenosed elastic artery is numerically examined. the model is carried out for axisymmetric, two-dimensional and fully developed blood flow. the vessel wall is assumed to be have time-dependent radius that is important factor for study of blood flow. the cosine-shape stenosis convert to rigid artery by using a ...

Results from numerical simulations and guidance from an approximated corrected-theory, developed by Oliveira and Pinho (1997), (Oliveira, P.J. and Pinho, F.T. 1997. Pressure drop coecient of laminar Newtonian ̄ow in axisymmetric sudden expansions. Int. J. Heat and Fluid ̄ow 18, 518±529) have been used to arrive at a correlation expressing the irreversible loss coecient for laminar Newtonian ̄...

This paper provides a review of shape analysis methods. Shape analysis methods play an important role in systems for object recognition, matching, registration, and analysis. Research in shape analysis has been motivated, in part, by studies of human visual form perception systems. Several theories of visual form perception are brie y mentioned. Shape analysis methods are classi ed into several...
