Very high transformation strainsweremeasured during isobaric experiments at temperatures up to Af= 420 °C. For the [111]B2 orientation in tens...

A system for measuring the absolute spectral responsivity of solar cells is described. The system uses higher-powered LED arrays that are coupled to an optical light guide that together provide large area illumination. Two different measurement methods were developed and tested using this measurement apparatus. The first method is an individual LED lock-in technique that can be performed over a...

High-pulse-energy supercontinuum radiation with a width exceeding 900 nm in the near-infrared spectral region has been generated in conventional single-mode fibre. The fibre was pumped at 1064 nm which is in the normal dispersion regime, resulting in predominantly red-shifted spectral broadening. Supercontinuum pulse energies exceeding 450 nJ were obtained. The use of conventional fibre allows ...

A critical task in network processing is packet analysis that includes operations like packet classification, filtering, and inspection. These operations are commonly based on matching headers and/or data within packets to rules inside a rule-set database. Consequently, the matching procedure determines how packets are classified. When matched, the same database contains the actions to be taken...

Abstract: Horizontal continuous casting is widely used to produce semi-finished and finished metallic products. Homogeneity in metallurgical characteristics and mechanical properties in such products is of importance. In the present work microstructure and mechanical properties of a horizontal continuous cast pipe have been studied. Microstructural features were investigated by an optical mi...

Mass spectrometry-based proteomics has greatly benefitted from enormous advances in high resolution instrumentation in recent years. In particular, the combination of a linear ion trap with the Orbitrap analyzer has proven to be a popular instrument configuration. Complementing this hybrid trap-trap instrument, as well as the standalone Orbitrap analyzer termed Exactive, we here present couplin...

In the present work, the behavior of Cu-Cr powder mixtures during mechanical alloying has been studied. The powder mixtures with 1, 3 and 6 weight percents of Cr in Cu were treated. They were milled in a ball mill with two different speeds of 250 and 500 rpm using equal numbers of 1 and 2 centimeters balls. The weight ratio of balls to powders was 10 to 1 under argon atmosphere. Ethanol was use...
