This study is based on measurements of trapped and precipitated electrons of energy >30 keV and >100 keV observed by polar orbiting environmental satellites during overpasses of the imaging riometer at Kilpisjärvi, Finland. The satellites are in s

The effects of energetic electron precipitation into the auroral region at a time of enhanced solar wind have been investigated during a continuous period of 24 h, using the European Incoherent Scatter (EISCAT) radar, an imaging riometer, and part

Observations by incoherent-scatter radar have been applied to explore relationships between the fluxes of incident protons and the resulting D-region electron densities during a polar-cap radio-absorption event. Using proton flux data from a GOES

Heightened perception of gastrointestinal sensation is termed visceral hypersensitivity (VH) and is commonly observed in patients with gastrointestinal disorders. VH is thought to be a major contributory factor in oesophageal disease, particularly ga

Ferroelectric liquid crystal displays offer an attractive matrix addressed alternative for complex displays. However, their potential can only be realised by using novel addressing schemes suitable for the fast responding, DC sensitive, ferroelectric

Photonics in Switching.
The use of free-space optics to perform high bandwidth connections for computing applications has been widely discussed in the literature. In this paper we present the practical results of a free-space optical crossbar switch which uses a ferroelectr
