Interaction potentialsof rare gases withmetal surfaces are calculated and compared with experimental data. A local dielectric function formalism and the density functional method are used in the calculation of the attractive and repulsive energies respectively. Depth and curvature variations of the potentials suggest a classification into light (He, Ne) and heavy rare gases. Sensitivity of the ...

Information about non-functional properties (NFPs) is rarely explicitly described in Service Oriented Architecture (SOA) services. In particular, there is still no standardized solution addressing what service providers should expose or advertise as NFPs in service descriptions to empower service consumers to decide whether a given service suits best their needs or not. Our goal is to define a ...
