Abstract In forming processes, friction is a local phenomenon influenced by the contact conditions at tool-sheet metal interface. A multi-scale model applicable for coated sheets developed boundary lubrication regime which accounts physical behavior of coating and measured surface topographies sheet tools. The patches therefore real area determined interface different loading conditions. single...

Oxide heterostructures have been shown to exhibit unusual physics and hold the promise of novel electronic applications. We present a set of criteria to select and design interfaces, particularly those that can sustain a high-density twodimensional electron gas (2DEG). We describe how first-principles calculations can contribute to a qualitative and quantitative understanding, illustrated with ...

Abstract: Elliptic interface problems arise in various areas of science and engineering. The steady state heat conduction in layered bodies is one of the largest areas of application of elliptic interface problems. In this paper, a mathematical model and solution of a one dimensional elliptic interface problem which represents a steady state heat conduction problem in composite medium have been...

Computer simulation of modern accelerator system is based on a number of specialized computer codes. Complexity of concerned processes and interpretation of simulation results requires comfortable and effective tools to design accelerator structure and beam characteristics, carry out computer experiments, process and visualize data. This paper proposes a prototype system with web-interface whic...

zinc coating is formed by the heterogeneous assembly of the γ, γ1, δ, ζ and η phases whose mechanicalproperties greatly differ from each other. thermal strains resulting from large differences betweenthermal expansion coefficients are partially relaxed by the formation of a crack network. in order tomodel this phenomenon, initial hardness, thermal expansion coefficient αi and toughness (kic) of...

In this work we provide a basic physical modeling of the spatiotemporal pattern of emulsification produced by chemical reaction-driven tip-streaming and observed by Fernandez and Homsy @Phys. Fluids 16, 2548 ~2004!#. Features of this phenomenon—nonlinear autooscillations, a conical drop shape, tip-streaming, and droplet trajectory splitting—are addressed in this paper. In particular, the experi...

backgroud: protein-protein interaction, plays a key role in signal transduction in signaling pathways. different approaches are used for prediction of these interactions including experimental and computational approaches. in conventional node-edge protein-protein interaction networks, we can only see which proteins interact but ‘structural networks’ show us how these proteins interact which ca...

in this paper, the interface crack of two non-homogenous functionally graded materials is studied. subsequently, with employing the displacement method for fracture of mixed-mode stress intensity factors, the continuous variation of material properties are calculated. in this investigation, the displacements are derived with employing of the functional graded material programming and analysis o...

A quantitative description of the dynamics of droplet motion has been a long-standing concern in electrowetting research. Although many static and dynamic models focusing on droplet motion induced by electrowetting-on-dielectric (EWOD) already exist, some dynamic features do not fit these models well, especially the dynamic saturation phenomenon. In this paper, a dynamic saturation model of dro...
