Within computational grids, some services (software components, linear algebra libraries, etc.) are made available by some servers to some clients. In spite of the growing popularity of such grids, the service discovery, although efficient in many cases, does not reach several requirements. Among them, the flexibility of the discovery and its efficiency on wide-area dynamic platforms are two major...
DIET (Distributed Interactive Engineering Toolbox) is a set of hierarchical components to design network enabled server (NES) systems. In these systems, clients ask to agents (discovery and scheduling components) to find servers able to solve their problem using some performance metrics and information about the location of data already on the network. Today's NES middleware, in which agents are statically...
We report the successful deposition of mono- and multilayers of azopoly-L-lysine (APLL), a synthetic polypeptide to which an azobenzene moiety has been added as a side chain. Such a molecule in solution shows phototropism, due to light-induced trans-cis isomerization. The Langmuir-Blodgett (LB) deposition was difficult due to the very high viscosity of the Langmuir monolayer; we were able however...
