It is vital to be able to rapidly assess damaged ship structures. This ensures the safety of personnel and facilitation of the most effective repair or recovery. Interframe progressive collapse analysis has been used as a method for rapid assessment for vessels but its suitability for application to damaged vessels has been questioned, due to the limited failure modes assessed and modelling assumptions...
Thermal voltage converters and transfer standards are critical components in AC electrical metrology. In order to improve the low-voltage (< 1 V) calibration of such transfer standards at NIST, we have developed an AC Josephson voltage standard (ACJVS) capable of an rms output of 200 mV from a single Josephson array. Such voltages are possible because the array operates in the n = 2 quantum voltage...
Acid oxidised multiwall carbon nanotubes (COOH-MWCNT) have been introduced as a hole injection buffer layer in an organic light emitting diodes (OLED). We show that the OLED with COOH-MWCNT as a buffer layer provides higher brightness with lower operating voltages. The addition of a COOH-MWCNT buffer layer has enabled a further increase in the brightness of our OLED devices operating in excess of...
