Phenomena at hot-wire electrodes
Fresenius' Journal of Analytical Chemistry, 2000An overview is given describing phenomena at heated microelectrodes where matter and heat energy are simultaneously emitted into the solution. With controlled electric heating, virtual "quiescent" periods as well as ones with constant streaming conditions are found that depend on the heating time.

Hot Wire and Hot Film Anemometers
1980Hot wire and hot film sensors are used for measurements of fluctuations in the wind. Such anemometers are in competition with both mechanical and sonic anemometers. At least some of the mechanical sensors are more stable in calibration, and less expensive. The high frequency resolution of the hot wire/hot film sensors, however, cannot be matched by any

Journal of Scientific Instruments, 1929
Instruments based on the convective cooling of an electrically heated wire, for giving the distribution of velocity across a liquid (a) flowing in a cylindrical tube, (b) flowing in the annular space between two concentric cylinders, one rotating and the other at rest, are described.

Journal of Physics E: Scientific Instruments, 1982
The region of validity of conventional hot-wire signal analysis and the accuracy of the values of the flow parameters calculated using this analysis have been investigated and an alternative analysis of hot-wire signals is proposed. Furthermore, the loss of accuracy is determined in the values obtained for the flow parameters when the cooling ...

Bidirectional hot-wire anemometer
Review of Scientific Instruments, 1982A simple hot-wire anemometer based device has been designed and developed which is capable of measuring flow reversals. The instrument has a useful range of 0 to ±150 cm/s.

In response to the 'digital divide', national and local governments in the UK, the US and Australia have embarked on various initiatives designed to promote the use of computer networks in low-income communities. These initiatives involve common models of self-help and mutual obligation; the pattern is one where government provides seed funding to ...
