A quantitative model describing the nucleation, energy, and diffusion restraints in reshaping of Ni nanoparticles as a catalyst of carbon nanotubes is developed by introducing the size-dependent thermodynamic quantities in the classical nucleation theory and the diffusion laws. The result from our model calculations is in good agreement with that of the latest time-resolved, high-resolution in ...

A combined BEM-FEM model has been developed to simulate the dynamic interaction between non-linear waves and an impermeable seawall with a submerged rubble toe over a sand seabed. A poro-elastic finite element model has been developed and used under the surface pressure computed by the BEM-FEM model. Modified Navier-Stokes equations are used to solve the flow inside the porous media and Biot's ...

In planning the construction of a seawall, it is necessary to consider several things, such as incoming waves, types defensive units, and economic factors. So for type size armor unit used, expected that structure will only experience minimal damage. addition, there are other considerations, wave reflection by structure. port area, with low needed keep anchored pool calm. this study, experiment...

The Integrated Care Network (ICN) provides information and support to frontline NHS and Local Government organisations seeking to improve the quality of provision to users, patients and carers by integrating the planning and delivery of services. Key to the role of the ICN is the facilitation of communication between frontline organisations and central government, so that policy and practice in...

This paper addresses the effect of probabilistic selling on inventory decisions and the expected profit through demand reshaping and demand substitution. By considering a scenario with two higher-priced specific products and one lower-priced probabilistic product, we construct a new newsboy-type inventory model with demand reshaping and substitution. A simulation study is implemented to explore...

The manufacturing of the non-circular pipes made by reshaping process is becoming more and more important because of their utilizations as in different industries. In this work, a reshaping process is presented with cold rolling of a circular thick tube into a square cross section between four flat rolls in different passes. The influence of the amount of roll gap reduction in each pass on the ...
