When solid materials and devices scale down in size, heat transfer from the active region to the gas environment becomes increasingly significant. We show that the heat transfer coefficient across the solid-gas interface behaves very differently when the size of the solid is reduced to the nanoscale, such as that of a single nanowire. Unlike for macroscopic solids, the coefficient is strongly p...

The accumulation of contaminating materials on the rotor blades of a gas turbine flowmeter is a condition of concern to the manufacturers, since it can lead to loss of calibration. Over time, a deposit of tar and heavy oil mixed with sand and dust can build up on the rotor blades, which causes the meter factor to change from its original value of calibration. A novel neural-network technique is...

The customer information system (CIS) is a vital component of the meter-to-cash (M2C) value chain for electric utilities and other industries that provide metered delivery of commodities such as water and natural gas. It is the glue that binds the consumption and metering process to payments, collections and other downstream processes that affect a company’s top line. Yet CIS transformations ca...

SYMPOSIUM PROCEEDINGS I956 The bottleneck in the application of indirect calorimetry is still the need for laborious and skilful gas analysis. I t is this bottleneck that is now under attack in this laboratory. If the attack is successful, the results will be, first a robust oxygen analyser for laboratory use, with a very short response time and small dead space, and later an adaptation of it s...
