User Interface Patterns are not sufficiently explored at the Conceptual phase. Work in area of User Interface patterns is predominantly done at design phase but not enough work is dedicated to analysis patterns. This paper shows different examples of abstract user interface patterns and explores the impact of such patterns in the software lifecycle. Conceptual User Interface Patterns can be use...

Numerical simulation of two-phase flow with imbedded interface of discontinuity is challenging in two major aspects. First, the interface can undergo change, merge and breakup during the course of the simulation. Examples of current successful methods in modeling flow with interface are, among others, the volume-of-fluid method, fronttracking method, and level-set method. Second, flow variables...

Magnetic tunnel junctions with an Fe3O4 top electrode have been fabricated. High resolution transmission electron microscopy (HRTEM) shows that in as-deposited state, Fe and FeO phases exist at the interface. These two phases are believed to have formed as a result of the unstable plasma condition at the start of the Fe3O4 deposition. A relatively low magnetoresistance ratio (MR) (3.5%) and low...

This paper presents a comprehensive model coupling the effects of hydrostatic stress, surface/interface stress, phase transformation and the structure of electrodes. First, the governing equation of moving phase interface with hydrostatic stress is established. Under the effect of hydrostatic stress, phase transformation process is much faster, which means phase transformation time is overestim...

Adaptive interface-Mesh un-Refinement (AiMuR) based Sharp-Interface Level-Set-Method (SI-LSM) is proposed for both uniform and non-uniform Cartesian-Grid. The AiMuR involves interface location dynamic un-refinement (with merging of the four control volumes) Cartesian grid away from interface. solver only. A detailed numerical methodology presented ghost-fluid method SI-LSM. Advantage novel as c...

in this research, fabrication of an in-situ composite via aluminothermic combustion synthesis in al–v2o5 system has been investigated. for this purpose, the mixed powders of al and v2o5 with molar ratio of 28 to 3 were ball milled and then compressed. differential thermal analysis was used to evaluate the temperatures of phase transitions. using the peak temperature of the reactions, the sample...

In this thesis, computational interface capturing methods for mathematical models related to fluid phase change processes in porous media are studied. The mathematical models are often singular and degenerate, which contributes to the computational difficulty. An analysis of a smoothing method applied to a one dimensional free interface problem is presented. An asymptotic analysis shows the dep...

A multi-phase smoothed particle hydrodynamics (SPH) method for both macroscopic and mesoscopic flows is proposed. Since the particle-averaged spatial derivative approximations are derived from a particle smoothing function in which the neighboring particles only contribute to the specific volume, while maintaining mass conservation, the new method handles density discontinuities across phase in...

The wetting and contact angle hysteresis on chemically patterned surfaces in two dimensions are analyzed from a stationary phase-field model for immiscible two phase fluid. We first study the sharp interface limit of the model by the method of matched asymptotic expansions. We then justify the results rigorously by the Γ-convergence theory for the related variational problem and study the prope...
