• A simplified model is developed for tunnel-soil-building interaction problems. The soil response represented by a nonlinear Winkler model. soil-foundation provides good match with 3D finite element analysis. Frictional sliding at the interface significant mechanism. Shallow tunnel construction inevitably causes local ground movements to occur. In an urban environment, these may cause damage e...

Systematic mapping of genetic-interaction networks will provide an essential foundation for understanding complex genetic disorders, mechanisms of genetic buffering and principles of robustness and evolvability. A recent study of signaling pathways in Caenorhabditis elegans lays the next row of bricks in this foundation.

The interaction paradigm is the foundation of many practical and theoretical computational issues. Roughly speaking, interaction involves communicating entities which evolve in parallel and may synchronize together. Communicating entities are usually viewed through public interfaces due to their black-box foundation. It is now widely accepted that such interfaces have to take into account behav...

We present a new abstract machine for interaction nets and demonstrate that an implementation based on the ideas is significantly more efficient than existing interaction net evaluators. The machine, which is founded on a chemical abstract machine formulation of interaction nets, is a simplification of a previous abstract machine for interaction nets. This machine, together with an implementati...

Abstract A novel numerical methodology is presented to solve the dynamic response of railway bridges under passage running trains, considering soil–structure interaction. It advantageous compared alternative approaches because it permits, (i) consideration complex geometries for bridge and foundations, (ii) simulation stratified soils, and, (iii) solving train-bridge problem at minimal computat...

In this paper, it is tried to find an approximate single layer equivalent for multi-layer graphene sheets based on third order non-local elasticity theory. The plates are embedded in two parameter Winkler-Pasternak elastic foundation, and also the thermal effects are considered. A uniform transverse load is imposed on the plates. Applying the non-local theory of Eringen based on third order she...

In present study, thermo-elastic buckling analysis of multi-layer orthotropic annular/circular graphene sheets is investigated based on Eringen’s theory. The moderately thick and also thick nano-plates are considered. Using the non-local first and third order shear deformation theories, the governing equations are derived. The van der Waals interaction between the layers is simulated for multi-...

Dynamic dam-foundation interaction is great important in the design and safety assessment of dam structures. Two classic boundary conditions, i.e., viscous-spring viscous boundary, are employed to consider radiation damping unbounded rock foundation. The input models seismic excitation derived. accuracy two conditions dynamic analysis foundation verified through using an impulsive load. influen...
