A genetic algorithm for ground-state structure optimization of a Palladium atomic cluster has been developed and ported on a SIMDMIMD parallel platform. The SIMD part of the parallel platform is represented by a Quadrics/APE100 consisting of 512 floating point units while the MIMD part is formed by a cluster of workstations. The proposed algorithm contains a part where the genetic operators are applied...
In this work we present a multichannel chemical sensor based on Surface Plasmon Resonance (SPR) in a Plastic Optical Fiber (POF), for the detection of metal ions. The SPR sensing platform was realized removing the cladding of a plastic optical fiber along half circumference, spin coating on the exposed core a buffer of Microposit S1813 photoresist, and finally sputtering a thin gold film by using...
We report on an recent European Project aimed at assessment of suited Methodologies to measure interdependencies between the Electric and the ICT System. Based on best practices and available data, several different metrics have been defined. Depending on the methodology involved, three main types of metrics can be identified; namely “topological”; “system theory based” and “simulation based” metrics...
The three INMs involved in the JRP e-MASS project operate three different absolute gravimeters, which rely on three different measurement methods. METAS operates a commercial FG5 gravimeter, INRIM has been developing his own ballistic symmetrical rise-and-fall gravimeter IMGC-2 and LNE-SYRTE develops a cold atom gravimeter. These gravimeters are briefly described in this paper and their differences...
The e-MASS joint research project (JRP) supported by EURAMET gathers several European metrology institutes in the aim to improve existing watt balances and to contribute to a new definition of the mass unit. This paper describes the main technical tasks developed in the framework of the project.
During the last years man efforts have been devoted to inspect the inter-dependence among critical infrastructures. Even assuming that the asset owners are supposed to handle their own possible misbehaviours properly, critical events maybe triggered by infrastructure's interactions. Therefore the need to handle and possibly measure inter-dependencies. Within this perspective, the EU funded MIA project...
Absolute gravity measurements are based on the reconstruction of the free-falling motion of a test body in vacuum. In this paper, two large disturbing effects are studied, namely, the non- gravitational accelerations originated by rotation and translation of the flying body. Their contribution to the uncertainty of the free-fall acceleration is evaluated using the method proposed in Supplement 1 to...
Today's most accurate measurements of the gravitational acceleration are based on interferometric reconstruction of the vertical trajectory followed by a test body launched in a vacuum chamber. The gravity value g is one of the parameters of a model function derived from the law of motion of the body, and is estimated by a least squares adjustment. In this paper we present the regression analysis...
