This paper presents a methodology for the characterization and the industrial testing of a very complex Application-Specific Integrated Circuit (ASIC). The proposed test system is being installed at a company and it is very user friendly also for a non specialized operator. This framework has been developed within a collaboration by the Istituto Nazionale di Fisica Nucleare (INFN) and the Laboratoire de Physique Nucléaire et de Hautes Energies (LPNHE), and the same test setup is installed in the laboratories of INFN-Milan, INFNFrascati and LPNHE-Paris.

In this paper we propose a new method for the automatic design of classification systems for the visual inspection of metallic surfaces. Feature selection and selection of a suitable classifier as well as its optimization are done fully automatically on the base of a set of representative images for all quality respective defective classes to distinguish. Texture and colour features, which are most suitable for discrimination between different quality classes, are also explained. Furthermore, we present a flexible software architecture based on Windows Workflow Foundation and Windows...

Comprehensive analysis of the angular and linear accelerations of the moving elements (shafts, gears) allows to increase quality of the condition monitoring of the mechanisms. However, existing tools and methods measure either linear or angular acceleration with postprocessing. The research suggests a new construction design of the angular acceleration sensor for the moving elements. Besides, the authors introduce the method for the received information processing, that makes it possible to divide the measured acceleration into the angular and linear components. The study has shown that this...

The present paper proposes to investigate the effect of pulsed Program/Erase cycling on Flash memory devices. Usually, electrical operations related to said devices involve the application of single long pulses to various terminals of the memory transistor to induce various tunneling effects allowing the variation of the floating gate charge. According to the literature, the oxide degradation occuring in such cases can be reduced by replacing DC stress by AC stress of the MOS-based devices. After a brief presentation of the functioning of the Flash memory transistors tested in this work, the...

In the last two decades, the scientific community has become aware of the fact that the real climate signal in original series of meteorological data is generally hidden behind non-climatic noise caused by a number of factors. Time series of meteorological data can therefore not be used for climate research without facing this issue. In this context, we have recently set up a database of Italian sunshine duration and solar radiation daily records and we have subjected them to a detailed quality check and homogenization procedure. Moreover, as the records are rather sparse and a significant...

The article is devoted to the measurement challenge associated with thermal monitoring that occurs during the heat treatment of products. We propose a method for calculating temperature values at internal points of a cylindrical body based on measuring the temperature functions on the surface of the body. The method for calculating temperature values involves the solving an inverse problem for a nonlinear parabolic equation with unknown initial conditions. The computational scheme is based on the use of finite-difference equations and a regularization technique. The reliability and...

The segmental nature of the support system, the interaction mechanism between concretegrout-soil and the complex installation process a bored tunnel are the main factors influencing the lining structural behavior. The main purpose of this study is to provide a two dimensional numerical model of segmental lining which takes into account the first two factors for the preliminary interpretation of the experimental data obtained by long-term monitoring of the strains in the instrumented segments of a precast segmental ring of Naples Metro Line 6. This model can be extended to three dimensions...

Monitoring the displacements of the buildings during the execution of underground works is a very demanding activity in large urban areas contexts, due to the number of structures involved and to the duration of the measurements throughout the realization time. Therefore, the surface deformation detection cannot be based on direct measurements using ground-based sensors, only, and should include technologies that allow a systematic and comprehensive monitoring. The satellite DInSAR technique (Differential Interferometry Synthetic Aperture Radar) provides displacement time series of a large...

The paper reports some geotechnical aspects of the design and construction of the San Pasquale Station, intermediate along the stretch of Line 6, which walks across the coastline named Riviera di Chiaia. The station required an excavation deeper 27 m, almost entirely located in pyroclastic sand below the groundwater table. The main shaft is 85.5 m long and 24.1 m large, containing the whole length of the pedestrian platform while a single large section tunnel, built before the excavation of the station shaft, accommodates the two operating rail tracks. Monitoring data will be presented and...

An integrated marine geophysics and satellite remote sensing study of Naples Bay (Italy) has been carried out to evaluate the presence, magnitude, areal extent and activity of the Naples Active Deformation Line (NADEL), a structural bend affecting the post Last Glacial Maximum (LGM) sedimentary sequences. Sparker high-resolution mono-channel profiles and multibeam swath bathymetric data were acquired during the SAFE_2014 research cruise, carried out on board of the Urania R/V of CNR on August 2014. The marine geophysical study was integrated with the ground deformation field of the emerged...
