Image blending is very important for image stitching with visible seams. An effective blending method for panoramic images in image-based virtual reality is proposed in this paper. The proposed blending method is a two-phase scheme. The histogram-based blending is first applied in the first phase scheme; and then in the second phase scheme, the weighted blending is used under the result of the ...

We present a sharp interface method for computing incompressible immiscible two-phase flows. It couples the Level-Set and Volume-of-Fluid techniques and retains their advantages while overcoming their weaknesses. It is stable and robust even for large density and viscosity ratios on the order of 1000 to 1. The numerical method is an extension of the second-order method presented by Sussman (200...

The problem of determining exact expressions for the effective stiffness tensor macroscopically anisotropic, two-phase composite media of arbitrary microstructure in arbitrary space dimension d is considered. We depart from previous treatments by introducing an integral equation for the “cavity” strain field. This leads to new, exact series expansions for the effective stiffness tensor of macro...

This research proposal presents a novel study that aims to contribute to the understanding of factors that impact on the performance of Australian university business school websites. The proposed study addresses the current limitations of website performance measurement and incorporates a multilevel perspective that accounts for user and organisational perspectives on website performance. This...

We introduce a robust method for computing viscous and viscoelastic two-phase bubble and drop motions. Our method utilizes a coupled level-set and volume-of-fluid technique for updating and representing the air-water interface. Our method introduces a novel approach for treating the viscous coupling terms at the air-water interface; these improvements result in improved stability for computing ...

Hydrodynamics of multiple rising bubbles as a fundamental two-phase phenomenon is studied numerically by lattice Boltzmann method and using Lee two-phase model. Lee model based on Cahn-Hilliard diffuse interface approach uses potential form of intermolecular forces and isotropic finite difference discretization. This approach is able to avoid parasitic currents and leads to a stable procedure t...

With the exponential growth of both the amount and diversity of the information that the web encompasses, automatic classification of topic-specific web sites is highly desirable. In this paper we propose a novel approach for web site classification based on the content, structure and context information of web sites. In our approach, the site structure is represented as a twolayered tree in wh...

In this paper we consider a nonlinear two-phase Stefan problem in one-dimensional space. The problem is mapped into a nonlinear Volterra integral equation for the free boundary.

In a recent article [1], the authors report evidence for an intriguing two-phase behavior of financial markets when studying the distribution of volume imbalance (Ω) conditional to the local intensity of its fluctuations (Σ). We show here that this apparent phase transition is a generic consequence of the conditioning and exists even in the absence of any non trivial collective phenomenon. More...

in this present study, volume of fluid method in openfoam open source cfd package will be extended to consider phase change phenomena with modified model due to condensation and boiling processes. this model is suitable for the case in which both unsaturated phase and saturated phase are present and for beginning boiling and condensation process needn't initial interface. both phases (liqu...
