Concerning measurements with dynamic pressure sensors, one of the most interesting aspects is the influence of a remoting system interposed between the sensor and the measurement point. This mounting system, once correctly characterized, allows one to use the same sensor for different measurement points, reducing the total number of sensors used. In addition, in all the applications involving high temperatures (e.g. combustion chamber), a remoting system allows the use of cheaper dynamic pressure sensors with lower operating temperature capability. A remoting system for dynamic pressure sensors made up by a remoting duct, between the sensor and the measurement point, followed by a damping duct has been characterized for different tube lengths. Tests were carried out with two kinds of sources: a diaphragm-less shock tube for the first set of tests and an acoustic speaker for the second. Results are here reported and commented.

AbstractElectromigration experiments have been carried out on simple Cu dual-damascene interconnect tree structures consisting of straight via-to-via (or contact-to-contact) lines with an extra via in the middle of the line. As with Al-based interconnects, the reliability of a segment in this tree strongly depends on the stress conditions of the connected segment. Beyond this, there are important differences in the results obtained under similar test conditions for Al-based and Cu-based interconnect trees. These differences are thought to be associated with variations in the architectural schemes of the two metallizations. The absence of a conducting electromigrationresistant overlayer in Cu technology, and the possibility of liner rupture at stressed vias lead to significant differences in tree reliabilities in Cu compared to Al.

Abstract Unidirectional cord-rubber specimens in the form of tensile coupons and sandwich beams were used. Using specimens with the cords oriented at 0°, 45°, and 90° to the loading direction and appropriate data reduction, we were able to obtain complete characterization for the in-plane stress-strain response of single-ply, unidirectional cord-rubber composites. All strains were measured by means of liquid mercury strain gages, for which the nonlinear strain response characteristic was obtained by calibration. Stress-strain data were obtained for the cases of both cord tension and cord compression. Materials investigated were aramid-rubber, polyester-rubber, and steel-rubber.
